Abstract

The invention relates to the technical field of brake calipers of automobiles, in particular to a brake caliper leaf spring and a brake caliper assembly. The brake caliper leaf spring comprises a leaf spring body; friction plate mounting parts are arranged on the leaf spring body; and a return drag hook is arranged in each friction plate mounting part. The brake caliper assembly comprises a brake caliper body, a piston, a support, two friction plates and a brake disc; the piston is arranged in the brake caliper body; the brake caliper body is connected with the support; the two friction plates are mounted on the support through the leaf spring body; the brake disc is arranged between the two friction plates; and after brake of an automobile is finished, the return drag hooks corresponding to the friction plates have the elastic force of which the direction is opposite to that of the clamping force of the friction plates when the friction plates clamp the brake disc. By the brake caliper leaf spring and the brake caliper assembly in the technical scheme of the invention, the inner friction plate and the outer friction plate can actively return well, so that dragging moment between the brake disc and the friction plates is reduced, oil consumption and CO2 emission of the whole automobile are reduced, and atmospheric contamination is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile brake caliper, in particular to a brake caliper spring plate and a brake caliper assembly. Background technique [0002] At present, regulations on vehicle fuel consumption and CO 2 Emission requirements are becoming more and more stringent, and the drag force of the brake caliper assembly directly affects its fuel consumption and CO 2 emissions, so low-drag torque calipers have become the research direction of major brake companies. [0003] The brake caliper assembly of the prior art includes a bracket and a brake disc. The bracket is connected with a caliper body. A piston is arranged in the cylinder hole of the caliper body. A spring leaf is arranged on the bracket. Both sides are provided with protrusions, and the protrusions of the friction plate are clamped in the spring plate, and the friction plate slides under the support of the spring plate, and forms a match with the brake disc. ...
