Example embodiments generally relate to brake lines and, more particularly, relate to a structure for securing the brake lines to a vehicle with a more simple installation procedure.
Vehicles may employ a variety of different systems for braking the vehicle, but in many cases these systems may have some similarities. For instance, many vehicles employ hydraulic brakes that use a hydraulic brake fluid to transmit a force applied to the brake pedal to brake calipers disposed at the wheels of the vehicle. Vehicles that use hydraulic brakes may include a brake booster to amplify the force applied to the brake pedal of the vehicle before transferring the force to a master cylinder and eventually to the brake calipers via brake lines. Thus, the brake lines may transmit the hydraulic brake fluid from the master cylinder to the brake calipers in order to engage the brakes and stop the vehicle. In this regard, the brake lines may include tubes or hoses that contain the hydraulic fluid therein, and may essentially operably couple the brake pedal to the brake calipers, allowing the operator of the vehicle to control the braking of the vehicle.
These brake lines, and many other components of the vehicle, are typically secured to the vehicle using various brackets and fasteners that all tend to lengthen the assembly process. Accordingly, there is a need to provide an upgraded attachment assembly for securing brake lines or similar components to the vehicle, which allows for simpler installation.
In accordance with an example embodiment, an attachment assembly for a fluid line on a vehicle of an example embodiment may be provided. The attachment assembly may include a spigot operably coupled to the fluid line such that automotive fluid may flow from the fluid line through the spigot, a coupling member which may operably couple the fluid line to the spigot, and a locking member which may be operably coupled to the coupling member to secure the fluid line to a chassis of the vehicle via insertion of the locking member into a bore disposed at the chassis of the vehicle. The locking member may be installed on the vehicle by hand without the use of tools.
In another example embodiment, a vehicle brake system may be provided. The vehicle brake system may include a wheel of a vehicle, a chassis of the vehicle to which the wheel may be operably coupled, a brake caliper which may be disposed at the wheel and may be operably coupled to the chassis, a brake line which may be operably coupled to the chassis via an attachment assembly, and may provide hydraulic force to operate the brake caliper accordingly, and a brake pedal which may be operably coupled to the brake line. The attachment assembly may include a spigot operably coupled to the fluid line such that automotive fluid may flow from the fluid line through the spigot, a coupling member which may operably couple the fluid line to the spigot, and a locking member which may be operably coupled to the coupling member to secure the fluid line to a chassis of the vehicle via insertion of the locking member into a bore disposed at the chassis of the vehicle.
In yet another example embodiment, a method of installing a brake line in a vehicle may be provided. The method may include connecting a spigot to a brake caliper to permit fluid flow between the brake line and the brake caliper via inserting a locking member, operably coupled to the brake line via a coupling member, into a bore that may be disposed at a chassis of the vehicle, and rotating the locking member relative to the bore until the locking member may enter a locked position responsive to the locking member being rotated to an end of a first thread assembly and a second thread assembly.
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Some example embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and pictured herein should not be construed as being limiting as to the scope, applicability or configuration of the present disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable requirements. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term “or” is to be interpreted as a logical operator that results in true whenever one or more of its operands are true. As used herein, operable coupling should be understood to relate to direct or indirect connection that, in either case, enables functional interconnection of components that are operably coupled to each other.
Some example embodiments described herein may address the problems described above. In this regard, for example, some embodiments may provide an attachment assembly for automotive fluid lines such as brake lines that may make the lines easy to install. Some embodiments may provide for the attachment assembly to be installed by hand without requiring the use of tools. As a result, installation of the brake line or other automotive fluid line may require little effort, and the brake line may be secured in the proper location.
In an example embodiment, the mounting bracket 140 may be operably coupled to the spigot 130, and may also extend around and away from the spigot 130. In some cases, the mounting bracket 140 may be an example of a coupling member 145 that may operably couple the fluid line 110 to the spigot 130. In an example embodiment, the spigot 130 may extend through the mounting bracket 140, and the mounting bracket 140 may include an ear 142 that may extend away from the spigot 130 and may include an orifice 144. In this regard, the mounting bracket 140 and the spigot 130 may be fixedly operably coupled so that the spigot 130 and the mounting bracket 140 may move and be oriented as one structure. In some cases, the spigot 130 and the mounting bracket 140 may even be integrated in with each other, and may be formed from a same material. In an example embodiment, the mounting bracket 140 may be made out of a steel or other metal and may be brazed onto a crimp of the fluid line 110, proximate to the spigot 130. The ear 142 may extend away from the spigot 130 so as to allow room for the insertion of the locking member 150 through the orifice 144 without the locking member 150 interfering with the functionality of the spigot 130. In an example embodiment, the ear 142 of the mounting bracket 140 may extend in a direction substantially perpendicular to the direction of extension of the spigot 130. In this regard, the locking member 150 may be inserted through the orifice 144, into the bore 160 within the chassis 120, and accordingly extend parallel to the spigot 130.
The locking member 150 may operably couple the coupling member 145, and thus the fluid line 110, to the chassis 120 of the vehicle. In some embodiments, the locking member 150 may resemble a pin or a plug, and the locking member 150 may be inserted into the bore 160 in the chassis 120 via the orifice 144. In other words, a body 152 of the locking member 150 may be substantially cylindrical in shape and may have an outer diameter not larger than a diameter of the orifice 144 so that the body 152 may be inserted through the orifice 144 with ease, and into the bore 160. The locking member 150 may also include a flanged end 154 at a first end of the body 152 of the locking member 150, and a handle 156 disposed on an opposite side of the flanged end 154 from the body 152. In some cases, the locking member 150 may be 3D printed or otherwise formed from a plastic (e.g. ABS plastic) or a similar material. The flanged end 154 may have an outer diameter greater than the diameter of the orifice 144 so that the locking member 150 does not extend through the orifice 144 beyond the flanged end 154 when operably coupling the mounting bracket 140 to the chassis 120. The handle 156 disposed on the flanged end 154 may resemble a protrusion that may help a person installing or tightening the locking member 150 to rotate the locking member 150 by hand relative to the orifice 144 when entering the bore 160. In other words, the mounting bracket 140 and the bore 160 may not rotate responsive to the locking member 150 being rotated. In this regard, the locking member 150 may be a cam lock that may effectively lock the mounting bracket 140 to the chassis 120 via the bore. In other words, the locking member 150 rotates to either secure or release the mounting bracket 140 from the chassis 120, and as the locking member 150 rotates to secure the mounting bracket 140 to the chassis 120, the locking member 150 may move the mounting bracket 140 and the spigot 130 into more secure contact with the chassis 120 via the flanged end 154. Thus, the locking member 150 may be classified as a cam lock due to functioning as a locking mechanism to move the mounting bracket 140 and spigot 130 into a secure position relative to the chassis 120. Accordingly, the locking member 150 may thus allow the fluid line 110 and the attachment assembly 100 to be installed (e.g. tightened) on to the vehicle without requiring the use of tools.

In this regard, the compressible member 158 may bias the first and second complimentary thread members (172, 182) into contact with the retention tabs 159 at the end of the first and second thread assemblies (170, 180), respectively, responsive to the locking member 150 being rotated into the locked position. In some cases, the compressible member 158 may be a rubber gasket or o-ring disposed around the body 152 of the locking member 150 proximate to the flanged end 154. In another example embodiment, the compressible member 158 may include a tab operably coupled to a spring that may be depressed responsive to the locking member 150 entering the locked position. By design, a number of rotations of the locking member 150 to secure the locking member 150 into the bore 160 in the locked position may be a direct result of the pitch of the first and second thread assemblies (170, 180). According to an example embodiment, the locking member 150 may enter the locked position responsive to being rotated 180° (i.e. one half turn) within the bore 160. In some other cases, the locking member 150 may enter the locked position responsive to completing one or more full rotations within the bore 160.
An attachment assembly for a fluid line on a vehicle of an example embodiment may therefore be provided. The attachment assembly may include a spigot operably coupled to the fluid line such that automotive fluid may flow from the fluid line through the spigot, a coupling member which may operably couple the fluid line to the spigot, and a locking member which may be operably coupled to the coupling member to secure the fluid line to a chassis of the vehicle via insertion of the locking member into a bore disposed at the chassis of the vehicle. The locking member may be installed on the vehicle by hand without the use of tools.
The attachment assembly of some embodiments may include additional features, modifications, augmentations and/or the like to achieve further objectives or enhance performance of the attachment assembly. The additional features, modifications, augmentations and/or the like may be added in any combination with each other. Below is a list of various additional features, modifications, and augmentations that can each be added individually or in any combination with each other. For example, the locking member may include a first thread assembly and a second thread assembly which may each be disposed to curve radially while extending axially along the locking member and may be 180° apart from each other on the outer surface of the locking member. In an example embodiment, the first thread assembly and the second thread assembly may be disposed 180° apart from each other on the outer surface of the locking member. In some cases, the bore may include a first complimentary thread member and a second complimentary thread member which may each be disposed on an inner surface of the bore. In an example embodiment, the first complimentary thread member and the second complimentary thread member may be disposed 180° apart from each other on the inner surface of the bore. In some cases, the first complimentary thread member may align with, and may enter, the first thread assembly on the locking member and the second complimentary thread member may align with, and may enter, the second thread assembly on the locking member, responsive to the locking member being inserted into the bore in a proper orientation. In an example embodiment, the first thread assembly may be sized to only allow the first complimentary thread member to enter the first thread assembly. In some cases, the locking member may include a retention tab at respective ends of each of the first and second thread assemblies which may retain each of the first and second complimentary thread members to secure the locking member in place responsive to the locking member being rotated to the end of the first and second thread assemblies. In an example embodiment, the locking member may further include a compressible member. In some cases, the compressible member may bias the locking member away from the bore and may bias the first and second complimentary thread members into contact with the retention tabs at the end of the first and second thread assemblies, respectively, responsive to the locking member being rotated to the end of the first and second thread assemblies. In an example embodiment, a number of rotations to secure the locking member to the bore in a locked position may be a direct result of a pitch of the first and second thread assemblies. In some cases, the locking member may enter the locked position responsive to being rotated 180° within the bore. In an example embodiment, the fluid line on the vehicle may be a brake line.
A vehicle brake system of an example embodiment may therefore be provided. The vehicle brake system may include a wheel of a vehicle, a chassis of the vehicle to which the wheel may be operably coupled, a brake caliper which may be disposed at the wheel and may be operably coupled to the chassis, a brake line which may be operably coupled to the chassis via an attachment assembly, and may provide hydraulic force to operate the brake caliper accordingly, and a brake pedal which may be operably coupled to the brake line. The attachment assembly may include a spigot operably coupled to the fluid line such that automotive fluid may flow from the fluid line through the spigot, a coupling member which may operably couple the fluid line to the spigot, and a locking member which may be operably coupled to the coupling member to secure the fluid line to a chassis of the vehicle via insertion of the locking member into a bore disposed at the chassis of the vehicle.
A method of installing a brake line in a vehicle may therefore be provided. The method may include connecting a spigot to a brake caliper to permit fluid flow between the brake line and the brake caliper via inserting a locking member, operably coupled to the brake line via a coupling member, into a bore that may be disposed at a chassis of the vehicle, and rotating the locking member relative to the bore until the locking member may enter a locked position responsive to the locking member being rotated to an end of a first thread assembly and a second thread assembly.
