Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, in particular to a disc brake with high stability. Background Art

[0002] Scooters, bicycles, electric bikes, and motorcycles are used worldwide as a means of transportation, mobility, and fitness. Brakes are essential components for regulating speed and braking. Currently, the most common brakes on scooters, bicycles, and electric bikes use mechanical cable-operated disc brakes. These disc brakes typically require adjusting the brake handle to control the movement of the brake pads, clamping the brake disc, and applying the brakes.

[0003] The brake pads in existing disc brakes are mostly round in shape. During use, the plate drives the brake pad to move and contact the brake disc. The contact area between the brake pad and the brake disc is small, which easily leads to insufficient friction. When using quadrilateral brake pads for work, long-term use and multiple friction of the brake pads can easily cause position offset or shifting, affecting subsequent braking work and making it difficult to guarantee the service life.

Moreover, the movement of multiple pressure balls has rolling contact and shifting on the positioning plate at multiple positions, keeping the overall balance of the positioning plate and ensuring that friction is reduced during the rolling process, thereby ensuring the service life.
