It is understandable that the main body 100 may be a long beam-like structure or a rectangular plate-like structure, as long as the sliding assembly 200, the jaw assembly 300 and the traction module 400 can be provided with installation positions. In this embodiment, the main body 100 is a long beam-shaped structure.

The sliding assembly 200 is mounted on the main body 100. The sliding assembly 200 can move relative to the main body 100 along the length of the main body 100, and is used to guide the sliding direction of the jaw assembly, such as The two ends, or other directions relative to the main body, are mainly used to guide the jaw assembly to move to the position on the hub for installing the jaw assembly.

Wherein, the length direction of the main body refers to the direction pointed by the longer side of the main body, as shown in FIG. 1 where the center line P of the main body 100 is located. It is understandable that the sliding rail 210 can be integrally arranged on the main body, and its length is approximately the same as the length of the main body, or the sliding rail 210 can be arranged on the main body in sections. On both sides of the, the respective lengths of the two sections of sliding rails 210 satisfy the requirements of the jaw assembly being suitable for different wheel hub sizes.

In some embodiments, the sliding assembly may be a combination of a guide shaft (not shown) and a sleeve (not shown) in addition to the combination of the sliding rail and the slider. In this case, the guide The shaft is fixedly installed on the main body, and the central axis of the guide shaft is separated from the main body by a predetermined distance. The sleeve is sleeved on the guide shaft and can slide along the central axis of the guide shaft. At least one sleeve is installed in the jaw assembly. It is understandable that the center axis of the guide shaft is parallel to the length direction of the main body (ie, the center line P in FIG. 1) and is separated by a predetermined distance, so that there is sufficient space between the guide shaft and the main body. There is a space for the sleeve to move, and it is also convenient for the claw assembly 300 not to interfere with the main body during the movement.

As shown in Figures 4-5, the claw assembly 300 includes a support base 310, an extension arm 320, and a claw 330.

In this embodiment, there are two sets of the claw assemblies 300, and the two sets of the claw assemblies 300 are located on both sides of the traction module 400, respectively. A set of the claw assembly 300 is installed on one of the sliding blocks 220. In this way, the two sets of claw assemblies 300 can be adjusted in position on the main body 100 to adapt to hubs of different diameters.

Specifically, during installation, the jaw assembly 300 is first fixedly installed with the sliding block 220, and then the two sliding blocks 220 are respectively installed into the sliding rail 210 from both ends of the sliding rail 210. Finally, the sliding rail 210 is installed in the receiving groove 110 of the main body 100, and the traction module 400 is located between the two sets of claw assemblies 300 at this time. With the above structure, the two sets of claw assemblies 300 can directly slide on the sliding rail 210 through the slider 220, so that the claws 330 can be clamped to hubs of different diameters.

In some embodiments, the claw assembly 300 may also adopt another installation method. The specific structure is: a set of the sliding assembly 200 is installed on opposite sides of the main body 100, and the first extension block 312 and the second extension block 313 extend and protrude from both sides of the main body 100. The first extension block 312 and the second extension block 313 are respectively mounted with a sliding block 220.

One end of the traction member 430 It is fixedly installed on the rotating wheel 410, the other end of the traction member 430 passes through the opening 4117 and is fixed to the fixing block 340, and the resetting member 430 is installed on the rotating wheel 410. Wherein, the traction member 430 connects the pawl assembly 300 and the runner 420, the runner 420 is installed in the middle of the main body 100, the runner 420 can rotate relative to the main body 100, so The runner 420 is used to accommodate the traction member 430 so that the traction member 430 adapts to the movement of the claw assembly 300. When an external force acts on the claw assembly 300 to cause the claw assembly 300 to move the traction module 400 in the reverse direction, The resetting member 440 is used to generate a pulling force on the pawl assembly 300 through the traction member 430, so that after the external force is removed, the pawl assembly 300 moves in the direction of the traction module 400 under the pulling force, and can be reset to no external force. The position when it exists, facilitates the disassembly and installation of the hub device on the hub. In this embodiment, the central axis of the positioning hole 120 coincides with the central axis of the traction module 400. Here, the coincidence of the two central axes means that the traction module is aligned with the center of the hub to ensure that the positioning hole is aligned with the center of the hub. , That is, the central axis of the positioning hole 120, the central axis of the traction module 400 and the central axis of the hub coincide. It is understandable that the above-mentioned three central axes, or the superposition of two of the three centers described in this application does not require strict coincidence, and a certain error is allowed, that is, each central axis can be deviated by a certain angle, As long as it does not affect the calculation and calibration accuracy of the vehicle calibration equipment. Alternatively, the three central axes can be deviated by a certain angle, which can be compensated for by other methods, such as calibration calculation algorithms. Here, the coincidence of the central axes described in this application includes the above-mentioned various situations. The storage box 410 includes a box body 411 and a box cover 412, the box body 411 is installed on the main body 100, and the box cover 412 is closed on the box body 411. The box body 411 is provided with the receiving cavity 4111, and the bottom of the box body 411 extends toward one side of the box cover 412 to form a mounting shaft 4112, a positioning protrusion 4113, and a boss 4114. The bottom of the box body 411 is provided with a through hole 4115, and a mounting block 4116 is fixedly installed on the side of the box body 411 away from the box cover 412. The box cover 412 is provided with a mounting seat 4121 on a side away from the box body 411, and the box cover 412 is also provided with the through hole 4115.

The runner 420 includes an inner tube 421, an outer tube 422, and a connecting plate 423. Two ends of the connecting plate 423 are connected to the outer wall of the inner tube 421 and the inner wall of the outer tube 422, respectively. The inner cylinder 421 is sleeved on the mounting shaft 4112 so that the rotating wheel 420 can rotate around the mounting shaft 4112. Wherein, both ends of the inner cylinder 421 respectively extend outward to form protrusions 4211. One side of the runner 420 abuts against the boss 4114 to support the runner 420, while reducing the contact area between the runner 420 and the box body 411, so as to reduce the box The friction between the body 411 and the runner 420. The central through hole of the runner 420 refers to the central through hole 4212 of the inner cylinder 421.

It is understandable that the shape of the runner 420 can be in addition to a cylindrical shape, but also other shapes, such as an elliptical cylindrical shape. Preferably, the runner 420 is cylindrical.

For the traction member 430, one end is fixedly installed on the runner 420, and the other end is wrapped around the outer wall of the outer cylinder 422 and extends into and is fixed in the groove 341 of the fixing block 340. It is understandable that the traction member 430 may be a cloth belt or a steel wire rope, of course, it may also be other solid wires that can be wound around the outer cylinder 422, and the traction member 430 may be elastic or inelastic. The length of the traction element can be adapted to the maximum hub radius, or the length of the traction element can be determined on demand. In this embodiment, the traction member 430 is a cloth tape, one end of the cloth tape is fixed and tied to the outer wall of the outer tube 422, and the other end is wrapped around the outer wall of the outer tube 422 and fixed to the fixing block 340 .

As for the restoring member 440, it is installed on the rotating wheel 420. The restoring member 440 may be a torsion spring 441, a spring, or even others. In this embodiment, the restoring member 440 is a torsion spring 441, the torsion spring 441 is sleeved on the protrusion 4211, and one end of the torsion spring 441 is inserted into the through hole 4115, and the torsion spring 441 is inserted into the through hole 4115. The other end of the spring 441 extends into the space between the inner tube 421 and the outer tube 422, and this end abuts the connecting plate 423.

It is understandable that when a force is applied to the pawl assembly 300 and moves in a direction away from the rotating wheel 420, the rotating wheel 420 rotates around the mounting shaft 4112 to release the traction member 430 At the same time, the reset member 440 is compressed. When the pawl assembly 300 is not subjected to external force, the restoring member 440 will resume deformation, the runner 420 will rotate in the opposite direction, and the runner 420 will wind up the traction member 430 to pull the pawl The assembly 300 moves in a direction close to the traction module 400.

It should be noted here that when there are two sets of the jaw assembly 300, the traction member 430 has two pieces, namely a first traction member and a second traction member, and the first traction member and the second traction member are mutually Independently and wound around the rotating wheel 420. That is, one ends of the first traction member and the second traction member are first fixed to the runner 420, and the other ends of the first traction member and the second traction member are wound around the runner 420 several times at intervals And the other end of the first traction member is fixed to a fixing block, and the other end of the second traction member is fixed to the other fixing block. When the runner 420 rotates in the first direction, the runner 420 synchronously rewinds the first traction member and the second traction member, so that the traction module 400 simultaneously draws the two jaw assemblies 300 toward the traction module 400. When the runner 420 When rotating in the second direction, the second direction is opposite to the first direction, for example: the first direction is clockwise and the second direction is counterclockwise, or the first direction is counterclockwise and the second direction is clockwise , The traction module 400 synchronously releases the first traction member and the second traction member, and the two pawl assemblies 300 can move synchronously away from the traction module 400, so that the movement of the two pawl assemblies 300 relative to the traction module 400 is synchronized. Further, the shape of the runner 420 is circular, so that when the runner 420 is rotating, the length of the runner 420 for rewinding or releasing the first traction member and the second traction member is the same, which improves the two jaws. The symmetry and balance of the position of the assembly 300 relative to the traction module 400.
