The output shaft of the electric cylinder 12 drives the wedge plate 13 to move in a direction away from or toward the electric cylinder 12. Since the thickness of the wedge plate 13 decreases in the direction away from the electric cylinder 12, when the total thickness of the wedge plate 13 and the simulation block 14 needs to be increased, the wedge plate 13 can be moved in a direction away from the electric cylinder 12, so that the total thickness of the wedge plate 13 and the simulation block 14 increases, which is used to simulate the change in the total thickness of the brake disc and friction pad.

[0027] Furthermore, the mechanism for verifying the durability of the compensation function also includes: a bracket 15, a guide column A16, a limit plate 17 and a deep groove bearing 18. The bracket 15 is fixed in the support seat 11; two parallel fixing plates 19 are protruding from the bracket 15, and the wedge plate 13 is arranged between the two limit plates 17. The electric cylinder 12 is fixed on the bracket 15, and the output shaft of the electric cylinder 12 passes through the bracket 15 and is connected to the wedge plate 13; the guide column A16 is passed through the bracket 15, and one end is connected to the wedge plate 13; the limit plate 17 is fixed on the support seat 11, and the guide column A16 is passed through the limit hole of the limit plate 17; the bracket 15 is fixed in the support seat 11 through the deep groove bearing 18.

[0033] Furthermore, the mechanism for verifying the durability of the compensation function further includes a limit block 54 , which is fixed on the platform 51 and located on one side of the support plate 41 .

[0034] Working principle: fix the brake on the sample tooling 61 and position it on the platform 51 by the positioning block 62; move the support plate 41 along the length direction of the slide 52, move the support seat 11 along the length direction of the support shaft 43, and then move the experimental support seat 11 left and right, front and back in the horizontal direction, so that the structure composed of the wedge plate 13 and the simulation block 14 (used to replace the change in the total thickness of the brake disc and the friction pad) is placed in the brake, and the wedge plate 13 is controlled by the electric cylinder 12 to move toward or away from the brake. Since the thickness of the wedge plate 13 decreases in the direction away from the electric cylinder 12, the more the fixed wedge plate 13 moves toward the brake, the thickness of the wedge plate 13 and the simulation block 14 increases, thereby simulating the change in the total thickness of the brake disc and the friction pad, which is used to verify the durability of the compensation function.
