Wherein, the locking module 300 can lock or release the synchronization assembly 200, and the claw assembly 400 is used for being clamped to the wheel hub, so that the wheel hub clamping device 900 is attached to the wheel hub.

When the locking module 300 is in the released state, move one of the claw assemblies 400 close to the locking module 300, and the synchronizing assembly 200 drives the other claw assembly 400 to approach the locking module synchronously 300, so that the locking module 300 is always in the middle of the two claw assemblies 400; when the locking module 300 is in the locked state, the two claw assemblies 400 are relative to the locking module 300 is fixed, and the central axis of the locking module 300 coincides with the central axis of the wheel hub. Therefore, when the wheel hub clamping device 900 is applied to the four-wheel alignment of the wheel, it can be installed on the wheel hub through the two jaw assemblies 400, and the synchronizing assembly 200 can drive the two The jaw assemblies 400 move the same distance to ensure that the locking module 300 is always in the middle of the two jaw assemblies 400, thereby ensuring that the central axis of the locking module 300 can coincide with the central axis of the hub or approximately coincident.

It can be understood that the above-mentioned two central axes described in this application do not require strict coincidence, and certain errors are allowed, that is, each central axis may deviate by a certain angle, as long as the calculation and calibration accuracy of the vehicle calibration equipment is not affected. Can. Alternatively, the two central axes may deviate by a certain angle, which can be compensated for by other means, such as a calibration calculation algorithm, etc. Here, the coincidence of the central axes described in this application includes the above-mentioned situations.

As shown in FIG. 3 , the main body 100 includes a first substrate 110 , a second substrate 120 and a connecting column 130 . The first substrate 110 and the second substrate 120 are arranged at a predetermined distance. The connection The pillars 130 are connected to the first substrate 110 and the second substrate 120 . Wherein, the first substrate 110 is provided with two first protruding portions 111 with a certain distance between the two first protruding portions 111 , and the second substrate is provided with two second protruding portions 121 . The second protrusions 121 also have a certain distance.

It is understandable that the connecting posts 130 may be connected to the first substrate 110 and the second substrate 120 by connecting components such as screws, or may be connected by welding. Preferably, the connecting column 130 is connected with the first substrate 110 and the second substrate 120 by connecting parts such as screws, so as to facilitate the replacement of connecting columns 130 of different lengths to adapt to different sizes of hubs. Understandably, the length of the connecting column 130 can be adjusted according to the user's needs, and it is only necessary to ensure that the two jaw assemblies 400 can be connected to the wheel hub. It should be understood that the connecting column 130 is only for connecting the first substrate 110 and the second substrate 120 , and the shape of the connecting column 130 is not limited to a column shape, for example, it may be a rectangular parallelepiped or a cube.

The synchronizing assembly 200 includes a first runner 210 , a second runner 220 and a timing belt 230 , the first runner 210 and the second runner 220 are respectively installed on both sides of the main body 100 , and the first runner 210 and the second runner 220 can rotate relative to the main body 100 , and the synchronous belt 230 is sleeved on the first runner 210 and the second runner 220 .

A convex part 111 is connected, and the first runner 210 can rotate around the central axis of the rotating shaft. Similarly, the second runner 220 is mounted on two places of the second base plate 120 through another rotating shaft. between the second protrusions 121, and the second wheel 220 rotates around the other shaft. Therefore, when the timing belt 230 rotates, the first runner 210 and/or the second runner 220 rotate synchronously.

Of course, in some embodiments, the rotating shaft may be omitted. In this case, the opposite sides of the two first convex portions 111 extend outward to form two oppositely disposed convex blocks (not shown). The first runner 210 is installed between two oppositely arranged projections, and the first runner 210 rotates around the center line of the two projections. Similarly, the two second projections 121 The same settings can also be made.
