Description
Technical Field
The utility model relates to the field of motorcycle brake calipers, in particular to an integrated motorcycle brake caliper.
Background
The braking principle of a caliper brake, namely a brake caliper, for a motorcycle is as follows: the friction resistance among the inner brake shoe, the outer brake shoe and the brake disc is offset with the rotating force generated by the brake disc driven by the wheel of the motorcycle, so that the rotating speed of the wheel of the motorcycle is slowed down or stopped to realize the speed reduction or parking of the motorcycle. The degree of the braking effect (i.e. the reduction or stop of the rotation speed of the wheel of the motorcycle) is mainly represented by the control of the hydraulic pressure generated by the brake fluid stored in the caliper body under the operation of the external mechanism, i.e. the hydraulic pressure generated by the brake fluid stored in the caliper body under the operation of the external mechanism pushes the piston to move, the acting force applied to the inner brake shoe in a mechanical transmission manner and the opposite acting force generated by the fixed outer brake shoe are simultaneously applied to the brake disc, and when the wheel of the motorcycle drives the brake disc to rotate, a friction force is generated to counteract the rotating force generated by the wheel of the motorcycle driving the brake disc, so that the rotation speed of the wheel of the motorcycle is reduced or stopped. The compensation of the abrasion clearance of the inner brake shoe and the outer brake shoe is mainly realized in a floating mode among the brake shoes, the bracket component and the caliper body component. After the brake shoe is worn, the relative position of the brake shoe is controlled through the sliding between the bracket component and the caliper body component, so that the brake shoe wear clearance compensation is carried out.
