A plurality of automatic sprinklers 7 are installed at the bottom of the water outlet tank 6. A limiting mechanism for limiting the position of a friction block 9 is provided inside the outer box 1.

[0021] refer to Figure 2-Figure 5 The limiting mechanism includes a fixed plate 10, a limiting plate 11, a movable frame 12 and an electric slide rail 13. The fixed plate 10 is fixedly connected to the right side of the inner part of the outer box 1, and the movable frame 12 is slidably connected to the right side of the inner part of the outer box 1. The upper part of the movable frame 12 is fixedly connected to the limiting plate 11. The right part of the outer box 1 is installed with an electric slide rail 13 for driving the movable frame 12 to move left and right, and the movable frame 12 is installed on the electric slide rail 13.

[0022] Initially, the automobile brake to be tested includes a brake disc 8 and two friction blocks 9. The brake disc 8 is splined on the rotating shaft 2, the fixed plate 10 contacts the left side of the friction block 9 on the left, and the limit plate 11 contacts the right side of the friction block 9 on the right, thereby fixing the positions of the two friction blocks 9 by the fixed plate 10 and the limit plate 11.

[0023] The control motor 3 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the brake disc 8 to rotate together. The torque sensor 4 detects the stability and reliability of the torque performance of the automobile brake after multiple different braking times, and the fatigue of the automobile brake can be detected to ensure the driving safety and reliability of the automobile.

[0024] Cooling water is added to the water storage tank 5 through the water inlet pipe 51, and the cooling water enters the water outlet tank 6. After the automobile brake detection is completed, the automatic nozzle 7 is controlled to spray water onto the automobile brake, which can automatically and quickly cool the automobile brake and reduce the degree of damage to the automobile brake.
