The gear 5 56 drives the gear 4 54 to rotate to rotate the reciprocating threaded rod 1 53, so that the moving plate 2 52 drives the double-headed elastic expansion plate 51 to squeeze the spring 3 66 to move back and forth, and the double-headed elastic expansion plate 51 drives the square rod 413 to move back and forth in the square tube 412. The square rod 413 drives the rotating shaft 2 414 and the wheel hub 415 to be tested to move back and forth, so that the tire 416 in contact with the drum 21 shakes back and forth, simulating the influence of the vehicle shaking during normal driving on the wheel hub 415 to be tested;

[0093] The operation of the vibration simulation mechanism 5 drives the operation of the multi-road simulation mechanism 2, and drives the tire 416 and the wheel hub 415 in contact with it to rotate through friction, simulating the impact of the car running on different roads on the wheel hub. The steps are as follows:

[0094] The rotation of the third shaft 55 drives the sixth gear 510 to rotate, and the sixth gear 510 drives the second gear 26 in contact with it to rotate, and the second gear 26 drives the roller 21 to rotate through the fixed ring 25, and the rotation of the roller 21 drives the two wheel hubs 415 in contact with it to rotate, so as to simulate the wheel hubs running on the road surface 1 22, the road surface 23 and the road surface 3 24, and obtain the influence of the wheel hubs 415 to be tested on the extreme road surface;

[0095] The operation of the multi-road simulation mechanism 2 drives the gravity simulation mechanism 4 to operate synchronously, simulating the impact of uneven force on the wheel hub of the vehicle and the different weights of passengers on the rear wheel hub during the vehicle's driving. The steps are as follows:

[0096] The rotation of gear 26 synchronously drives gear 3 47, shaft 1 45 and bevel gear 2 46 to rotate. The rotation of bevel gear 2 46 drives bevel gear 1 43 and double-section reciprocating threaded rod 42 to rotate, so that two movable plates 1 49 drive telescopic rod 410 and spring 1 411 to move, pull square cylinder 412, square rod 413, shaft 2 414, wheel hub 415 to be tested and tire 416 to move toward roller 21, squeeze roller 21, increase the force on wheel hub 415 to be tested, so as to simulate the influence of different weights of vehicles on wheel hub 415 to be tested on extreme road surface. When movable plate 1 49 moves to the wire tail, it moves back to the wire tail and then turns off motor 71. At this time, tire 416 is at a certain distance from roller 21, and then road surface switching is performed.

[0097] Then, the motor 71 is started to drive the gear 1 72 to rotate in reverse. The reverse rotation of the gear 1 72 satisfies the one-way gear 2 63 to drive the reciprocating threaded rod 2 61 to rotate, so that the movable plate 3 64 drives the spring 3 66, the double-headed elastic telescopic plate 51, the square rod 413, the rotating shaft 2 414, the wheel hub 415 to be tested and the tire 416 to move, so that the tire 416 and the wheel hub 415 to be tested are switched to the road surface 2 23 or the road surface 3 24, and different obstacle road surface tests are performed. When moving, the gear 4 54 drives the gear 5 56 to slide on the rotating shaft 3 55 through the limit ring 57, so that the gear 4 54 is always meshed with the gear 5 56;

[0098] The industrial camera 32 transmits the image of the wheel hub 415 to be tested to the controller 8 , and the controller 8 compares the two wheel hubs 415 to be tested, and then analyzes the difference between different tires 416 of the same wheel hub 415 to be tested under the same road environment.

[0099] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
