Description

Technical Field

[0001] The utility model relates to the technical field of brake disc performance detection, in particular to a brake disc performance detection device. Background Technique

[0002] Simply speaking, a brake disc is a circular plate that rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force. When stepping on the brake, it clamps the brake disc to play a role in decelerating or stopping. The brake disc has good braking effect and is easier to maintain than the drum brake. After long-term use, the thickness of the brake disc will be reduced by the friction of the brake pads, resulting in an uneven friction surface of the brake disc. Therefore, it is necessary to regularly detect the performance of the brake disc to ensure that the brake disc can be used normally.

[0003] The patent with the publication number of CN208313182U discloses a brake disc standard surface detection device, including a detection device and a brake disc. The detection device is used to detect the surface flatness and thickness of the brake disc. The detection device includes a connecting rod, a fixed rod and a dial indicator. The connecting rod includes connecting rod A, connecting rod B and connecting rod C. The fixed rod includes fixed rod A, fixed rod B and fixed rod C. The dial indicator includes dial indicator A, dial indicator B and dial indicator C. The dial indicator A, dial indicator B and dial indicator C all include a meter body, a sleeve and a measuring head; the brake disc includes an inner brake disc and an outer brake disc. The beneficial effect of the utility model is that it can simultaneously measure the surface flatness of the inner brake disc and the outer brake disc and the thickness of the outer brake disc, with high working efficiency, high measurement accuracy, convenient measurement and low price;

[0004] However, the existing device still has the following problems: The dial indicator in this device measures the surface flatness and thickness of the brake disc. However, since there is no rotation assembly under the brake disc and it cannot drive the brake disc to rotate, when it is necessary to measure different positions on the surface of the brake disc, it is necessary to manually rotate the position of the dial indicator or manually rotate the brake disc, which is likely to lead to a reduction in the detection efficiency of the brake disc, and the brake disc or the dial indicator is likely to shift during the adjustment process, resulting in a reduction in the detection accuracy of the brake disc.

[0005] Therefore, a brake disc performance detection device is proposed. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides a brake disc performance detection device, which solves the problem that a dial indicator is used to measure the flatness and thickness of the surface of the brake disc. However, since no rotating component is provided under the brake disc, the brake disc cannot be driven to rotate. When it is necessary to measure different positions on the surface of the brake disc, it is necessary to manually rotate the position of the dial indicator or manually rotate the brake disc, which easily leads to a decrease in the detection efficiency of the brake disc, and the brake disc or the dial indicator is prone to deviation during the adjustment process, resulting in a decrease in the detection accuracy of the brake disc.

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions: A brake disc performance detection device includes a brake disc main body.
