Description

Technical Field

[0001] The present application relates to the technical field of brake calipers, and in particular to a wire-controlled brake caliper structure. Background Art

[0002] The brake caliper is a component that applies force to the protruding part of the brake disc on the outside of the brake pad. The hydraulic pressure generated by the master brake cylinder on the piston inside the caliper will push the brake pad toward the brake disc after the piston expands, which can enhance the braking performance.

[0003] At present, when the brake caliper is working, hydraulic oil is needed as the braking force transmission medium, and the brake pipeline needs to be configured to transport the hydraulic oil, which easily leads to leakage of the hydraulic oil and is not convenient for inspection and maintenance. Therefore, in order to solve the above problems, we provide a wire-controlled brake caliper structure. Utility Model Content
