Description

Technical Field

[0001] The utility model relates to the technical field of caliper disc brakes, and more specifically to a caliper disc brake. Background Art

[0002] Caliper disc brake is a common braking system. Caliper disc brake has the advantages of strong braking force, fast heat dissipation and long service life. Therefore, it is widely used in modern vehicles. At the same time, the design of caliper disc brake is also constantly improving to improve braking efficiency, reduce wear and noise and other performance.

[0003] The prior art discloses a utility model patent named "a hydraulic caliper disc brake" with application number CN202222424226.7. When the disc brake is used for braking, the position of the friction plate is adjusted according to the wear of the friction plate. First, the bolt is turned outwardly and the fixing nut is turned outwardly so that the fixing nut and the lower surface of the fixed caliper disc are no longer in contact. According to the compensation amount required, the screw head is rotated to drive the screw rod, so that the screw rod drives the support plate and the friction plate to move upward. The limit plates fixed on both sides of the fixed caliper disc can effectively limit the friction plate to avoid excessive compensation, thereby solving the problem that the wear of the friction plate cannot be compensated when the disc brake is used for braking.

[0004] However, when it is used, the compensation amount of the friction plate still needs to be adjusted manually, and the wear amount of the friction plate needs to be judged manually to determine the compensation amount, so there is a problem of inconvenience in adjustment when it is used.
