As pivot arm 301 rotates about an axis passing through its center, the ends of pivot arm 301 rotate in different directions, since the pivot arm 301 has both ends connected to the first link 302 and the second link 303, and the first link 302 is connected to the wheel set positioning member 201 of one wheel alignment assembly 20 by a first push-pull rod 304, the second link 303 is connected to the wheel set positioning member 201 of another wheel alignment assembly 20 by a second push-pull rod 305, therefore, the two ends of the pivoting arm 301 can drive the first link 302 and the second link 303 to move, the first link 302 drives the first push-pull rod 304 to move along the transverse direction of the vehicle, the second link 303 drives the second push-pull rod 305 to move along the transverse direction of the vehicle, and finally, the wheel surface positioning members 201 of the two wheel alignment assemblies 20 are driven by the first push-pull rod 304 and the second push-pull rod 305 to slide towards each other or in opposite directions, respectively, so that the two wheel alignment assemblies 20 synchronously move towards each other or in opposite directions. In a specific positioning process, when one of the wheel alignment assemblies 20 is adjusted, the wheel alignment assembly 20 drives the other wheel alignment assembly 20 to move synchronously through the synchronization mechanism 30.

In the embodiment, the synchronization mechanism 30 with the above structure can ensure a higher synchronization degree between the two wheel alignment assemblies 20 by using the pivot arm 301, the first link 302, the second link 303, the first push-pull rod 304 and the second push-pull rod 305 to form a synchronous linkage relationship.

In another embodiment of the present invention, the synchronizing mechanism 30 comprises a central gear, a first rack and a second rack (not shown), wherein the central gear is pivotally disposed on the base 10.

The first rack is slidably arranged on the base 10 along the second direction and is meshed with one side of the central gear; the second rack is slidably disposed on the base 10 along the second direction and engaged with the other side of the sun gear.

One of the two wheel alignment assemblies 20 is connected to the first rack and the other of the two gear alignment members is connected to the second rack.

When the central gear rotates, the first rack and the second rack can move in opposite directions, and one of the two wheel alignment assemblies 20 is connected to the first rack, and the other of the two gear alignment members is connected to the second rack, so that the first rack and the second rack can drive the two wheel alignment assemblies 20 to move synchronously.

In this embodiment, by using the gear-rack synchronizing mechanism 30, the first rack and the second rack form a synchronous motion relationship under the driving of the central gear, and it is also possible to ensure that the two wheel positioning elements have a higher degree of synchronization.

It is understood that the synchronizing mechanism 30 may also adopt other implementation manners known in the art, such as a positive and negative lead screw mechanism, etc., as long as the two wheel alignment assemblies 20 can synchronously move towards each other or towards each other, and the implementation manner of the synchronizing mechanism 30 is not limited in this application.

Referring to fig. 3 to 6, in an embodiment of the present invention, the hub center calibration apparatus further includes a second locking member 40, and the second locking member 40 is disposed on the tread positioning member 201 and is switchable between a locking state and an unlocking state.

When the second locking member 40 is in the locked state, the wheel alignment assembly 20 is locked to the base 10, and when the second locking member 40 is in the unlocked state, the wheel alignment assembly 20 is slidable relative to the base 10 in the second direction.

That is to say, the second locking member 40 can be switched between the locking state and the unlocking state through operation, for example, when the wheel face positioning member 201 needs to be adjusted in a sliding manner, the second locking member 40 can be switched to the unlocking state, and in the unlocking state, the wheel face positioning member 201 can slide relative to the base 10, and at this time, the wheel face positioning member 201 can be slid to a required position along the lateral direction of the vehicle as required. After the wheel-side positioning member 201 slides to the desired position, the wheel-side positioning member 202 abuts against the wheel side of the wheel 70, and the second locking member 40 is switched to the locking state, in which the wheel-side positioning member 201 and the base 10 are relatively fixed, so that the wheel-side positioning member 202 and the wheel side of the wheel 70 can be kept abutting against each other.

In this embodiment, the second locking member 40 is used to lock or unlock the wheel surface positioning member 201, so as to facilitate the operation of the positioning process of the wheel 70 and ensure reliable positioning.

Referring to fig. 5 and 6, in an embodiment of the present invention, a threaded hole 1011 is formed on the base 10, and a sliding hole 2011 is formed on the wheel alignment assembly 20, wherein the sliding hole 2011 extends along the second direction.

The second locking member 40 includes a screw 401, a pressing operation member 402 and a pressing pad 403, wherein one end of the screw 401 passes through the sliding hole 2011 and is in threaded connection with the threaded hole 1011.

The pressing operation member 402 has an operation end D40 and a connection end D41, the operation end D40 is suitable for being held and operated by a user, the connection end D41 has an eccentric portion 4021, and the eccentric portion 4021 is pivoted with the other end of the screw 401.

A pressure pad 403 is slidably inserted into the screw 401 and located between the wheel alignment assembly 20 and the eccentric portion 4021; when the operating end D40 is pressed, the eccentric portion 4021 presses the pressure pad 403, so that the pressure pad 403 presses and fixes the wheel alignment assembly 20 to the base 10.

In the example of fig. 5 to 6, the lower end of the screw 401 passes downward through the sliding hole 2011 of the wheel surface positioning piece 201 and is screwed with the threaded hole 1011 of the base 10, the upper end of the screw 401 is pivoted with the eccentric portion 4021 of the pressing operation piece 402, the pressure pad 403 is arranged on the screw 401 and located above the wheel surface positioning piece 201, and the eccentric portion 4021 is located above and in contact with the pressure pad 403.

When the locking state needs to be switched, the operating end D40 of the pressing operating element 402 can be rotated in one direction, so that the high point on the eccentric portion 4021 is rotated to be opposite to the pressure pad 403, and thus, the high point on the eccentric portion 4021 applies a downward pressure to the pressure pad 403, the pressure pad 403 presses the wheel surface positioning element 201 downward, and meanwhile, the screw 401 drives the base 10 to press the wheel surface positioning element 201 upward, so that the wheel surface positioning element 201 and the base 10 are pressed and fixed relatively, which is the locking state.

When the wheel surface positioning piece needs to be switched to the unlocking state, the operating end D40 of the pressing piece can be operated to rotate in the other direction, so that the low point on the eccentric portion 4021 rotates to be opposite to the pressure pad 403, and thus, because the distance from the low point on the eccentric portion 4021 to the rotation center on the eccentric portion 4021 is small, the pressure of the low point on the eccentric portion 4021 to the pressure pad 403 is small or no pressure, the pressing state between the wheel surface positioning piece 201 and the base 10 is released, and the wheel surface positioning piece 201 and the base 10 can slide relatively, which is the unlocking state.

In this embodiment, the second locking member 40 with the above structure can be switched between the locking state and the unlocking state quickly by the rotation operation of the pressing operation member 402, the operation is very convenient, and the wheel surface positioning member 201 and the base 10 can be reliably locked and fixed by applying the pressing pressure by the eccentric portion 4021.

Referring to fig. 5, in one embodiment of the present invention, the base 10 includes a carriage and moving wheels 103, and the moving wheels 103 are provided at the bottom of the carriage so that the base 10 can move.

In the example shown in fig. 5, the bearing frame includes a transverse carrier plate 101 and a longitudinal supporting rod 102, two wheel surface positioning elements 201 are slidably disposed at two ends of the transverse carrier plate 101, respectively, and one end of the longitudinal supporting rod 102 is vertically connected to the transverse carrier plate 101, so that the base 10 is conveniently moved by the moving wheels 103, and further, the wheel surface positioning elements 201 are conveniently adjusted to abut against the wheel surfaces of the wheels 70 during the positioning process.

Preferably, the base 10 is further provided with a shielding cover 104, and the shielding cover 104 covers the synchronization mechanism 30, so that the synchronization mechanism 30 can be hidden in the shielding cover 104, and thus, the synchronization mechanism 30 acts more reliably and safely, and can play a dustproof role in the synchronization mechanism 30, and the appearance of the hub center calibration device can be more concise and beautiful.

Advantageously, the base 10 is provided with a guide rail 11 extending along the second direction, the wheel surface positioning member 201 is provided with a sliding block 12, and the sliding block 12 is in sliding fit with the guide rail 11, so that the wheel surface positioning member 201 can reliably slide along the transverse direction of the vehicle through the sliding fit between the sliding block 12 and the guide rail 11 between the wheel surface positioning member 201 and the base 10.
