Description

Technical Field

[0001] The invention belongs to the technical field of brake disc jump detection, and in particular relates to a brake disc jump detection device. Background Art

[0002] Brake discs (also called brake discs) are important parts in cars, motorcycles and other mechanical equipment, used to reduce the speed of the vehicle or stop it through friction. Brake discs usually work together with brake calipers, brake pads and other components to form part of the braking system. The function of the brake disc is to transfer the braking force from the braking system to the wheels, generating enough friction to slow down or stop the movement of the vehicle. In addition to the size, there is another indicator that needs to be focused on when using a car brake disc: the amount of brake disc runout. This indicator directly affects the driving maneuverability. If this indicator does not meet the requirements, the steering wheel will shake or even the entire vehicle body will shake during the braking process of the driving vehicle.

[0003] The existing devices for detecting the end runout of the brake disc often use a micrometer as a measuring instrument, and the measured value is read by touching the surface of the brake disc and manually rotating the brake disc. However, this detection method easily leads to large measurement errors and low efficiency, which ultimately affects the detection accuracy of the brake disc and causes the detection data value to fail to meet the requirements. Therefore, we propose a brake disc runout detection device. Summary of the invention
