The present invention relates to press tools, systems, and methods and, more specifically, to press tools, systems, and methods that are adapted to remove a torque rod end from a structural support of a vehicle.
Torque rods are often used as part of the suspension system of modern vehicles such as trucks. The disassembly of a torque rod for repair and/or replacement typically requires that an end of the torque rod be detached from a structural support of the vehicle. Access to the torque rod end and the structural support may be limited, so removal of the torque rod end from the structural support using conventional tools can be difficult.
The need thus exists for improved tools, systems, and methods for facilitating the removal of a torque rod end from the flange of a vehicle, and that application of the present invention will be described herein.
The present invention may be embodied as a press tool for disconnecting a torque rod assembly from a structural support comprising an anchor plate, a brace plate, a drive rod supported by the brace plate, and a plurality of spacing members operatively connected to the anchor plate and the brace plate such that the press tool defines a tool opening. At least a portion of the torque rod end and the structural support are passed through the tool opening such that the anchor plate engages at least a portion of the structural member. The drive rod is axially rotated relative to the brace plate such that the drive rod engages at least a portion of the torque rod assembly and displaces the torque rod assembly relative to the structural support.
The present invention may also be embodied as a method of disconnecting a torque rod assembly from a structural support comprising the following steps. An anchor plate is provided. A brace plate is provided. A drive rod is supported on the brace plate. A plurality of spacing members is operatively connected to the anchor plate and the brace plate such that the press tool defines a tool opening. At least a portion of the torque rod end and the structural support is passed through the tool opening such that the anchor plate engages at least a portion of the structural member. The drive rod is axially rotated relative to the brace plate such that the drive rod engages at least a portion of the torque rod assembly and displaces the torque rod assembly relative to the structural support.
The present invention may also be embodied as a press tool for disconnecting a torque rod assembly from a structural support comprising an anchor plate, a brace plate, a securing plate, a drive rod supported by the brace plate, and a plurality of spacing members operatively connected to the anchor plate and the brace plate such that the press tool defines a tool opening. A plurality of securing members engaged with the plurality of securing members such that the securing plate is operatively connected to the brace plate. At least a portion of the torque rod end and the structural support are passed through the tool opening such that the anchor plate engages at least a portion of the structural member. The drive rod is axially rotated relative to the brace plate such that the drive rod engages at least a portion of the torque rod assembly and displaces the torque rod assembly relative to the structural support.

As illustrated in
With the first example press tool 20 in the desired configuration, the example press tool 20 is arranged such that at least a portion of the torque rod assembly 22 and at least a portion of the structural support 24 enters the tool opening 38 such that the brace plate 32 engages the structural support 24. The drive rod 34 is then axially rotated to cause the drive rod 34 to engage and displace at least a portion of the torque rod assembly 22 relative to the structural support 24 to disassemble the torque rod assembly 22 from the structural support 24.
With the foregoing general understanding of the construction and operation of the present invention in mind, the first example torque rod press tool 20, the example torque rod assembly 22, and the example structural support 24 will now be described in further detail.

The shape of the example brace inner edge 142 defines a brace plate configuration as depicted in
As perhaps best shown in
The exact brace plate configuration and the brace bore pattern are not critical so long as the press tool 20 of the present invention defines the tool opening 38 such that the press tool 20 may be arranged relative to the torque rod assembly 22 and structural support 24 as will be described in further detail below. The example brace plate configuration is generally round or semi-circular to facilitate manufacturing of the brace plate 32.
The example drive rod 34 defines a drive rod shaft 160, a drive rod head 162, and a drive rod end surface 164, as depicted in
Each of the first spacing members 36 defines a spacing member shaft 170, a spacing member head 172, and a spacing member anchor portion 174, as shown in
To assemble the example press tool 20, the anchor plate 30 and brace plate 32 are arranged such that the anchor bores 126 are aligned with the brace bores 148. The first spacing members 36 are then inserted through the brace bores 148 and axially rotated such that the spacing member anchor portions 174 threadingly engage the anchor bores 128. The brace plate 32 is then displaced relative to the anchor plate 30 such that the spacing member heads 172 engage the anchor bore engaging surfaces 154. At that point, the example press tool 20 is in its desired configuration. The brace plate 32 is configured to be easily removable and/or interchangeable if the example press tool 20 needs to be serviced, without taking the entire press tool 20 apart.
The brace retaining clips 158 may be inserted into the anchor bore clip recesses 156 to maintain the example press tool 20 in the desired configuration. The drive rod 34 is then inserted into the drive bore 146 and axially rotated in a first direction relative to the brace plate 32 such that the drive rod 34 threadingly engages brace plate 32. Further axial rotation of the drive rod 34 in the first direction relative to the brace plate 32 displaces the drive rod 34 relative to the brace plate 32 such that the drive rod end surface 164 is displaced towards the anchor plate 30 such that drive rod end surface 164 is arranged between the anchor inner surface 124 and the brace inner surface 142.

In the pre-operational configuration, the anchor plate 30 is arranged to engage the structural support 24, the drive rod 34 is substantially axially aligned with the torque rod pin 70, and the drive rod end surface 164 faces but is spaced from the torque rod pin 70. Axial rotation of the drive rod 34 in the first direction causes the drive rod end surface 164 to engage the torque rod pin 70. Because the anchor plate 30 is in contact with the structural support 24, a distance between the anchor plate 30 and the brace plate 32 is fixed by the first spacing members 36, and the drive rod 34 is supported by the drive bore 146 in the brace plate 32, continued axial rotation of the drive rod 34 in the first direction displaces the torque rod pin assembly 56, bushing 54, and torque rod end 52 relative to the structural support 24. Axial rotation of the drive rod 34 in the first direction eventually forces the torque rod pin 70 entirely out of the structure bore 60 as shown in
The example press tool 20 may also be used to facilitate removal of the bushing 54 from the torque rod end bore 64 to facilitate repair of the torque rod assembly 22. As shown in
In the pre-operational configuration, the anchor plate 30 is arranged to engage the torque rod end 52, the drive rod 34 is substantially axially aligned with the bushing bore 64 defined by the bushing 54, and bushing plate 180 on the drive rod end surface 164 faces but is spaced from the bushing 54. Axial rotation of the drive rod 34 in the first direction causes the bushing plate 180 to engage the bushing 54. Because the anchor plate 30 is in contact with the torque rod end 52, a distance between the anchor plate 30 and the brace plate 32 is fixed by the first spacing members 36, and the drive rod 34 is supported by the drive bore 146 in the brace plate 32, continued axial rotation of the drive rod 34 in the first direction displaces the bushing 54 relative to the torque rod end 52. Axial rotation of the drive rod 34 in the first direction eventually forces the bushing 54 entirely out of the torque rod end bore 62 as shown in
The drive rod 34 may be axially rotated by rotating the drive rod head 162 using a manual tool such as a wrench (not shown) sized and dimensioned to engage the drive rod head 162 or a power tool such as an impact driver (not shown) and a socket drive (not shown) configured to engage the drive rod head 162.
The example press tool 20 may also be used with additional brace plates, drive rods, and sets of spacing members (not shown). In particular, different brace plates with different configurations of tool opening 38 and brace inner surfaces 154 may be provided for different torque rod assemblies and structural supports. For example, a particular make and model of vehicle may employ a brace plate 32 having a given configuration, drive rod 34, and a set of spacing members 36 defining a given configuration and effective length based on the size, dimensions, and configuration of the torque rod assembly 22 and structural support 24 of that particular make and model of vehicle. The additional spacing members, if used, are or may be the same as the first example spacing members 36 except that an effective length of the spacing members in each additional set is different from an effective length of the first example spacing members 36. The use of one or more additional brace plates, drive rods, and sets of spacing members thus facilitates the reconfiguration of the example press tool 20 between two or more desired configurations selected based on the characteristics of the torque rod assembly 22 and structural support 24 on which the example press tool 20 will be used. The example press tool 20 can thus easily be reconfigured to accommodate different configurations of the torque rod assembly 22 and structural support 24 as determined by different environments in which the torque rod assembly 22 and structural support 24 are used.

The second example press tool 220 comprises an anchor plate 230, a brace plate 232, a plurality of spacing members 226, a securing plate 284, and a plurality of securing members 286. As described above, the size and configuration of the torque rod assembly 222 and the structural assembly 224, and the plurality of spacing members 226 is arranged to fix a distance between the anchor plate 230 and the brace plate 232.
The example anchor plate 230 and the brace plate 232 are or may be the same as the example anchor plate 230 and brace plate 232 described above and will not be described herein again in detail.
The anchor plate 230 defines a drive bore 346. In one embodiment, the drive bore may be threaded and configured to receive a drive rod 234 (not shown). The drive rod 234 may be the same or similar to the example drive rod 34, described above. In one embodiment, the drive rod 234 of the second example press tool 220 may use axial rotation to displace the torque rod assembly 222 from the structural assembly 224. In another embodiment, as shown in
Referring again to
The example securing members 300 defines a securing member shaft 302, and a securing member head 304, as shown in
Each of the plurality of spacing members 236 defines a spacing member shaft 370, a spacing member head 372, and a spacing member anchor portion 374, as shown in
The spacing member head portions 372 define an inner engaging surface 306 that is sized and dimensioned to receive at least a portion of an anchor portion of the securing members 300. The inner engaging surface 306 is threaded. The securing member shaft 302 of the securing members 300 is threaded to engage the threaded inner engaging surface 306 of the spacing members 236. The spacing members 300 are axially rotated such that the securing member shafts 302 are threadingly engaged to the spacing members 236 to prevent the securing members 300 from passing entirely through the securing plate 284. The length of the securing member shaft 302 determines a distance between the securing plate 284 and the brace plate 230.
The example brace rod 240 and brace nut 244 are or may be the same as the example brace rod 240 and brace nut 244 described above and will not be described herein again in detail.
To assemble the second example press tool 220, the anchor plate 230 and brace plate 232 are arranged such that the anchor bores 326 are aligned with the brace bores 348. The first spacing members 236 are then inserted through the brace bores 348 and axially rotated such that the spacing member anchor portions 374 threadingly engage the anchor bores 328. The brace plate 232 is then displaced relative to the anchor plate 230 such that the spacing member heads 372 engage the brace bore engaging surfaces 354. At that point, the second example press tool 220 is in its desired configuration. The securing plate 284 may be placed on top of the first spacing members 236 and secured by inserting the securing member shaft 302 through the securing bore 326 and threadingly engaging the securing member shaft 302 with the inner engaging surface 306 of the spacing members 236. The securing plate 300 and the anchor plate 232 may be easily removed and replaced if necessary.
The second example press tool system 220 is otherwise used in a manner similar to that of the first example bushing assembly insertion system 20 described above.
