Abstract
Fastening device on the outer tube of a shock absorber, comprising a receptacle for the connection to a vehicle axle and, optionally or in combination, additional mountings for a roll stabilizer and for brake hoses, whereby the connection and the additional mountings are at a distance from one another, characterized by the fact that the receptacle and the mountings are components of a one-piece fastening device, whereby the distance between the receptacle and the additional mountings is bridged by a connecting web.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a fastening device on the outer tube of a shock absorber, comprising a receptacle for connection to a vehicle axle and, optionally or in combination, additional mountings for a roll stabilizer and for brake hoses, whereby the connection and the additional mountings are at a distance from one another.
2. Background Information
On known shock absorbers, the receptacles or mountings for the steering stub axle, the brake hoses and the roll stabilizer are each usually formed by an individual part. That tends to result in positioning problems during the welding process. Generally, at least the roll stabilizer mounting and the receptacle for the steering stub axle must be at a certain distance from one another, because this distance tends to indirectly influence the prestress of the roll stabilizer. In known shock absorbers, the add-on parts were usually welded in complicated devices, which would limit the amount of automation which could be effectively used in the manufacturing process.
An additional disadvantage, for the roll stabilizer mounting in particular, resides in the fact that a weld seam must be laid down in the circumferential direction of the roll stabilizer mounting. To prevent the distortion of the outer tube, the weld seam is usually extended to run all the way around the outer tube, although that does not tend to increase the strength of the roll stabilizer mounting.
OBJECT OF THE INVENTION
The object of the present invention is to significantly reduce the time, effort and expense required to fabricate the above-mentioned add-on parts, to guarantee compliance with the specified tolerances or remain well within them, and to improve the utilization of the weld seams to increase strength.
SUMMARY OF THE INVENTION
The invention teaches that the above object is achieved by the fact that, preferably, the receptacle and the mountings are components of a one-piece fastening device, whereby the distance between the receptacle and the additional mountings is bridged by a connecting web.
The one-piece design of the fastening device significantly simplifies the construction of the necessary welding apparatus, since essentially all the angular measurements, in particular in the circumferential direction, have been taken into consideration as a result of the one-piece design of the part. The same is true for the distance between the receptacle for the steering stub axle and the roll stabilizer mounting. The achievable tolerance is determined exclusively by the blanking or stamping die. Tests have shown that the tolerance range can be reduced to as little as one-fifth of what it was previously, in known devices.
On the fastening device, moreover, the width of the connecting web essentially represents a ring-shaped section, whereby the inside diameter is preferably adapted to the outside diameter of the outer tube. The connecting web can advantageously be used for welding connections to the outer tube. Since the connecting web runs essentially in the direction of the principal axis of the outer tube, distortion is essentially impossible.
In particular for shock absorbers for front axles, it can be advantageous in terms of the utilization of material if the dimensions of the stamping blank for the fastening device are determined essentially by the distance between the two locator holes for the stabilizer and by the distance between the receptacle and the horizontal center line of the locator holes.
As a rule, motor vehicles do not tend to have a roll stabilizer on the rear axle. The dimensions of a stamping blank for the fastening device are correspondingly determined essentially by the distance between the two mountings for a brake hose, and by the distance between the receptacle and the connecting arms of the brake hose mounting.
In summary, one aspect of the invention resides in a shock absorber comprising: a sealed cylinder defining a chamber therein; the cylinder containing a damping fluid; a piston rod sealingly projecting into the cylinder and being axially displaceable with respect to the cylinder; a piston attached to the piston rod, the piston rod being disposed with the cylinder to sealingly divide the chamber into first and second chambers; means for permitting flow of damping fluid between the first and second chambers; a longitudinal axis; an outer tube being oriented along the longitudinal axis, the outer tube having an external surface; the piston rod and the chamber being disposed radially inwardly of the external surface of the outer tube; singular fastening means comprising: first means for fastening to a first external object; second means for fastening to a second external object; the singular fastening means being a single, integral unit comprising the first fastening means and the second fastening means; the singular fastening means being positioned on the external surface of the outer tube at a predetermined location on the external surface of the outer tube and being aligned along the longitudinal axis of the shock absorber in a predetermined position; and the singular fastening means being fixedly attached, as a single, integral unit, to the external surface of the outer tube of the shock absorber at the predetermined location and the predetermined position.
Another aspect of the invention resides broadly in a method of making a shock absorber, the shock absorber having a longitudinal axis, the method comprising the steps of: providing a sealed cylinder, the sealed cylinder defining a chamber therein, the cylinder containing a damping fluid; providing a piston rod, the piston rod sealingly projecting into the cylinder and being axially displaceable with respect to the cylinder; providing a piston, the piston being attached to the piston rod, the piston rod being disposed with the cylinder to sealingly divide the chamber into first and second chambers; providing means for permitting flow of damping fluid between the first and second chambers; providing an outer tube, the outer tube being oriented along the longitudinal axis, the outer tube having an external surface, the piston rod and the chamber being disposed radially inwardly of the external surface of the outer tube; the method further comprising the additional steps of: providing singular fastening means, the singular fastening means comprising: first means for fastening to a first external object; second means for fastening to a second external object; the singular fastening means being a single, integral unit comprising the first fastening means and the second fastening means; positioning the singular fastening means on the external surface of the outer tube at a predetermined location on the external surface of the outer tube and aligning the singular fastening means in a predetermined position along the longitudinal axis of the shock absorber; and fixedly attaching the singular fastening means, as a single, integral unit, to the external surface of the outer tube of the shock absorber at the predetermined location and the predetermined position.
Yet another aspect of the invention resides broadly in a shock absorber having a longitudinal axis, the shock absorber being made by a method comprising the steps of: providing a sealed cylinder, the sealed cylinder defining a chamber therein, the cylinder containing a damping fluid; providing a piston rod, the piston rod sealingly projecting into the cylinder and being axially displaceable with respect to the cylinder; providing a piston, the piston being attached to the piston rod, the piston rod being disposed with the cylinder to sealingly divide the chamber into first and second chambers; providing means for permitting flow of damping fluid between the first and second chambers; providing an outer tube, the outer tube being oriented along the longitudinal axis, the outer tube having an external surface, the piston rod and the chamber being disposed radially inwardly of the external surface of the outer tube; the method further comprising the additional steps of: providing singular fastening means, the singular fastening means comprising: first means for fastening to a first external object; second means for fastening to a second external object; the singular fastening means being a single, integral unit comprising the first fastening means and the second fastening means; positioning the singular fastening means on the external surface of the outer tube at a predetermined location on the external surface of the outer tube and aligning the singular fastening means in a predetermined position along the longitudinal axis of the shock absorber; and fixedly attaching the singular fastening means, as a single, integral unit, to the external surface of the outer tube of the shock absorber at the predetermined location and the predetermined position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1a and 1b illustrate an outer tube 1 for a shock absorber 3, which in this case is illustrated as a telescoping strut. A fastening device 5 is welded to its lower end. The fastening device 5 comprises, among other things, a receptacle 7 for a steering stub axle (not shown) of a motor vehicle. In the vicinity of the receptacle 7, the fastening device is preferably designed as a flat body. The receptacle 7 is connected to a connecting web 9. The width of this connecting web 9 preferably represents an essentially ring-shaped section 11, the inside diameter of which is preferably adapted to the outside diameter of the outer tube 1. The upper end of the fastening device 5 is preferably formed by a roll stabilizer mounting 13.
The one-piece design of the fastening device 5 makes it possible to achieve substantially exact dimensions and to observe tolerances for the distance between the receptacle 7 and the holes 15 of the roll stabilizer 13 much more closely than in other known devices.
There are also advantages in terms of the usable length of the weld seams. The connecting web 9, which runs essentially in the axial direction, offers many possible applications without any risk of distortion. The connecting web 9 can also permanently increase the rigidity of the fastening device 5.
In the illustrated configuration, the size of the stamping blank used for producing the fastening device can be determined essentially by the distance between the holes 15 of the roll stabilizer mounting 13 and the receptacle 7.
FIGS. 2a-c show a fastening device in isolation, like the one illustrated in FIGS. 1a and 1b. An additional component in FIG. 2 is a brake hose holder 17, which can alternatively be used to hold a brake wear indicator. In the circumferential direction, brake hose holder 17 encloses, that is, surrounds, the connecting web 9, whereby the length is selected so that in its development, it does not increase the width of the stamping blank.
FIGS. 3a-d show a fastening device 5, in particular as used for a shock absorber on a rear axle.
The receptacle 7 for the steering stub axle is essentially identical to those in the embodiments illustrated in FIGS. 1a, 1b, and 2a-2c. A brake hose mounting 17 is preferably used, which in turn is preferably coupled to the receptacle 7 by means of a connecting web 9. The connecting web 9 preferably includes a flat section which makes the transition into a ring-shaped section, to which are attached the mountings 17 for the brake hoses or ABS.
FIG. 3d shows very clearly the dimensions for a stamping blank. Essentially, the most important dimension is essentially the distance between the receptacle 7 and the brake house mounting 17 and the notches 19 of the brake hose mounting 17.
The disclosure now turns to a more detailed discussion of the preferred embodiments of the present invention.
In accordance with a preferred embodiment of the present invention, as shown in FIGS. 1a, 1b, 4a and 4b, fastening device 5 may preferably include a receptacle 7 for a steering stub axle of a motor vehicle and a roll stabilizer mounting 13. Receptacle 7 and roll stabilizer mounting 13 are preferably rigidly connected to one another via connecting web 9. A longitudinal axis 20 is preferably defined through the shock absorber in question and therefore through outer tube 1.
As shown in FIGS. 4a and 4b, roll stabilizer mounting 13 may preferably be embodied by two flat and coplanar sections 21 and a semiannular section 23 interconnecting the flat sections 21. A hole 15 is preferably disposed through each of the flat sections 21. Semiannular section 23 is preferably configured to interface in close contact with the external cylindrical surface of outer tube 1 of shock absorber 3, over about half of the circumferential extent of the external cylindrical surface of outer tube 1. Thus, the inner diameter of semiannular section 23 preferably essentially corresponds to the outer diameter of outer tube 1.
As shown, receptacle 7 is preferably indented into a longitudinal extension 25 of fastening device 5. Longitudinal extension 25 is preferably configured for being oriented longitudinally along the longitudinal extent of outer tube 1. Longitudinal extension 25 itself preferably lies in a plane which is parallel to the longitudinal axis 20 of outer tube 1 and shock absorber 3 and perpendicular to the plane in which flat sections 21 of roll stabilizer mounting 13 lie.
Preferably, in accordance with a preferred embodiment of the present invention, receptacle 7 may be indented into a lower portion 27 of longitudinal extension 25 of fastening device 5. Preferably, as shown, a major portion of longitudinal extension 25 of fastening device 5, and, accordingly, of connecting web 9, can be welded onto outer tube 1 by way of a longitudinal weld 29 whereas the aforementioned lower portion 27 is not. Thus, lower portion 27 of longitudinal extension 25 of fastening device 5 is preferably not in contact with the external surface of outer tube 1 and can preferably be slightly spaced apart therefrom. Receptacle 7 may preferably be embodied by a generally semi-circular slot, wherein the open portion of the slot faces outer tube 1 and opens into the space between lower portion 27 of lower portion 27 of fastening device 5 and the external cylindrical surface of outer tube 1. Roll stabilizer mounting 13 can preferably be welded onto outer tube 1 by way of longitudinal welds 30, one of which is shown in FIG. 4a.
Connecting web 9 is preferably configured to run longitudinally along outer tube 1 to connect roll stabilizer mounting 13 and longitudinal extension 25. As such, connecting web 9 is preferably embodied by a transition portion 31, an elongated neck portion 33 and a terminal portion 35. Neck portion 33 is preferably of a reduced circumferential extent, such as about 30 to 60 degrees, while transition portion 31 preferably rigidly connects semiannular portion 23 with neck portion 33 while making a smooth, curved transition between semiannular portion 23 and neck portion 33. A major portion of neck portion 33 is preferably welded to outer tube 1 by a second longitudinal weld 37, as shown. Terminal portion 35 preferably has a circumferential extent of about between 30 and 90 degrees, preferably greater than that of neck portion 33, and is preferably welded to outer tube 1 by way of a third longitudinal weld 39. Preferably, as shown, longitudinal extension 25, especially lower portion 27 thereof, extends a significant distance longitudinally beyond terminal portion 35 of connecting web 9.
It will be appreciated that the distance between holes 15 of roll stabilizer mounting 13, as well as the longitudinal distance between holes 15 and receptacle 7, can essentially serve as parameters for determining the size of the stamping blank for forming the fastening device 5 according to the present invention.
FIGS. 2a-2c and 5a-5c illustrate, in isolation, the fastening device 5 shown in FIGS. 1a, 1b, 4a and 4b. As shown, in accordance with another preferred embodiment of the present invention, a brake hose holder 17 may be included as part of fastening device 5. As shown, brake hose holder 17 may preferably be located between roll stabilizer mounting 13 and lower portion 25 of fastening device 5. Preferably, the length of the brake hose holder 17 can be chosen such that the width of the stamping blank used to form the fastening device is not increased.
FIGS. 3a-3d and 6a-6d illustrate a fastening device 5 which may preferably be utilized on a rear axle. Particularly, the fastening device 5 illustrated in FIGS. 3a-3d and 6a-6d does not have a roll stabilizer mounting.
Preferably, in the embodiment illustrated in FIGS. 3a-3d and 6a-6d, the receptacle 7 for the steering stub axle is essentially identical to that illustrated for the embodiment of FIGS. 1a, 1b, 4a and 4b, and that of FIGS. 2a-2c and 5a-5c. As shown, a brake hose holder, or mounting, 17 may preferably be included. Thus, in accordance with a preferred embodiment of the present invention, brake hose mounting 17 is preferably connected to receptacle 7 by means of connecting web 9.
As illustrated in FIGS. 6a-6c, connecting web 9 may preferably be embodied by a longitudinal extension 25, an arcuate portion 41 extending from longitudinal extension 25, and a lower, semiannular portion 43. Longitudinal extension 25, with receptacle 7 indented therein, may preferably be configured similarly to the longitudinal extension 25 of the embodiment of FIGS. 1a, 1b, 4a and 4b. Accordingly, longitudinal extension 25 can preferably be configured so as to be oriented along a radius of the shock absorber in question when placed on the shock absorber. Arcuate portion 41 preferably extends from a base of longitudinal extension 25, that is, from that portion of longitudinal extension 25 which will be adjacent outer tube 1 (not shown), and preferably describes an arc of about 90.degree. . When mounted on outer tube 1 (not shown), arcuate portion 41 will preferably interface in close contact with outer tube 1. Accordingly, the arc described by arcuate portion 41 preferably has a diameter roughly corresponding to that of the outer tube 1 on which the fastening device 5 is to be mounted.
Brake hose mounting 17 can preferably be embodied by two mounting portions 45, each of which preferably extends from semiannular portion 43. Each mounting portion preferably includes a base portion 47, wherein each base portion 47 is preferably configured to generally lie in a plane perpendicular to the longitudinal axis of outer tube 1 and perpendicular to the plane defined by longitudinal extension 25. Notches 19 are preferably embodied by generally circular holes, with a notch-like indentation opening into the circular hole. Notches 19 are preferably indented into base portions 47.
Preferably extending from each base portion 47, in a direction parallel to the longitudinal axis of the outer tube, are flange portions 49. Each mounting portion 45 preferably includes two such flange portions 49, and each flange portion 49 preferably extends towards receptacle 7.
As shown in FIG. 6b, the centers of the circular portions of notches 19 are preferably not aligned along a common axis, but are preferably aligned along axes which form a shallow acute angle, such as an angle of between about 3.degree. and about 15.degree., with respect to each other. In an alternative embodiment of the present invention, the centers of the circular portions of notches 19 may be aligned along a common axis.
FIG. 6d illustrates a stamping blank 5a which may preferably be utilized to form, i.e. by bending, the fastening blank 5 shown in FIGS. 6a-6c. Portions 25a, 41a, 43a and 45a for forming, respectively, longitudinal extension 25, arcuate portion 41, semiannular portion 43 and mounting portions 45, are illustrated. Portion 25a preferably includes receptacle 7a, as shown. It will be appreciated that the longitudinal distance between receptacle 7a and brake hose mountings 45a, as well as the distance between notches 19a, can preferably serve as important parameters for determining the size of stamping blank 5a.
FIG. 7 illustrates a shock absorber 100, having an outer tube 101, which may be utilized in accordance with the embodiments of the present invention. As illustrated in FIG. 6, an adjustable two-tube shock absorber can generally include a cylinder 1', which sealingly contains a hydraulic fluid, a piston rod 2', which piston rod 2' can sealingly project into cylinder 1' and which piston rod 2' can be axially displaceable with respect thereto, and a damping piston 3', which damping piston 3' can be sealingly disposed within cylinder 1' and can be connected to piston rod 2'. Piston rod 2' can be attached to a structure portion, e.g., of a vehicle, which is not shown. Piston 3' can divide cylinder 1' into upper and lower working chambers 4' and 5', respectively, and can be provided with axially throughgoing passages and associated bottle valves 8' of conventional design and well known in the art, which can provide a substantially constant and non-variable resistance to the axial displacement of piston 3' and piston rod 2'.
Two additional cylinders of progressively greater diameter, including a cylinder 22' and outer tube 101, can be disposed coaxially with cylinder 1', so as to surround cylinder 1', thereby providing two additional annular chambers, a bypass chamber 9' and an equalization chamber 21'. Bypass chamber 9' can preferably interconnect with the working chambers via orifices 23', and a valve 20', located at the bottom of cylinder 1'. The bypass chamber 9' can preferably provide a means by which the damping medium contained therein can reach equalization chamber 21'.
A damping force control unit 24', which can act hydraulically in parallel with throttle valves 8' to modify the substantially constant damping force which throttle valves 8' can provide, can be mounted as a separate component attached to the shock absorber, and can be in fluid communication with bypass 9' and equalization chamber 21'.
It should be understood that the shock absorber illustrated in FIG. 7 is provided as an example of a type of shock absorber on which the fastening device according to the present invention may be utilized, and that the fastening device according to the present invention may essentially be utilized on any appropriate shock absorber.
Based on the disclosure hereinabove, the advantages of a fastening device according to the present invention should generally be clear to a routineer in the field of the invention. It should also be appreciated that, according to another, alternative, embodiment of the present invention, a fastening device according to the present invention provides advantages during an automatic welding process. Particularly, whereas, in the case of prior known fastening devices, it would usually be necessary for two parts of a welding jig to hold separate corresponding fastening elements on the outer tube of a shock absorber during automatic welding, the single fastening element of the present invention would essentially only require that one part of a welding jig hold essentially the entire fastening element on the outer tube of a shock absorber during automatic welding. This would essentially provide advantages in terms of handling and precision.
One feature of the invention resides broadly in the fastening device on the outer tube of a shock absorber, comprising a receptacle for the connection to a vehicle axle and, optionally or in combination, additional mountings for a roll stabilizer and for brake hoses, whereby the connection and the additional mountings are at a distance from one another, characterized by the fact that the receptacle 7 and the mountings 13, 17 are components of a one-piece fastening device 5, whereby the distance between the receptacle 7 and the additional mountings is bridged by a connecting web.
Another feature of the invention resides broadly in the fastening device, characterized by the fact that the width of the connecting web 9 represents a ring-shaped section 11, whereby the inside diameter is adapted to the outside diameter of the outer tube 1.
Yet another feature of the invention resides broadly in the fastening device, characterized by the fact that the dimensions of a stamping blank for the fastening device 5 are determined essentially by the distance between the two locator holes 15 for the stabilizer and by the distance between the receptacle 7 and the horizontal center axis of the locator holes 15.
Still another feature of the invention resides broadly in the fastening device, characterized by the fact that the dimensions of a stamping blank for the fastening device 5 are determined essentially by the distance between the two mountings 17 for a brake hose and by the distance between the receptacle 7 and the connecting web 9 of the brake hose holder 17.
