Abstract

The invention relates to a sliding pin combination structure for a disk type brake. The sliding pin combination structure for the disk type brake comprises a bracket and a caliper body. The bracket is fixed to an axle and provided with a long sliding pin and a short sliding pin. The long sliding pin is fixed to the bracket through a long bolt, and the short sliding pin is fixed to the bracket through a short bolt. The long sliding pin is located in front of the driving direction of a car, and the short sliding pin is located at the back of the driving direction of the car. A long sliding pin lining is arranged outside the long sliding pin, and a short sliding pin lining is arranged outside the short sliding pin. The long sliding pin lining and the short sliding pin lining are arranged inside the caliper body. Sliding pin covers are arranged at the bottom of the long sliding pin and the bottom of the short sliding pin. The fit clearance between the short sliding pin and the short sliding pin lining is not smaller than that between the long sliding pin and the long sliding pin lining. Clamping stagnation faults of the brake are reduced through the short sliding pin, and it is ensured that guiding of the brake is more smooth and reliable through the long sliding pin. The axial movement of the caliper body is limited through the fit between the long sliding pin, the short sliding pin and the sliding pin covers, so that the situation that normal operating of the disk type brake is affected by excessive axial movement amount of the caliper body is prevented, and meanwhile collision between the disk type brake and the axle is avoided.

Description

technical field [0001] The invention belongs to the field of automobile braking equipment, and relates to an automobile brake sliding pin structure, in particular to a disc brake sliding pin combined structure, which can improve the braking effect of the brake on the automobile and prolong the service life of the brake. Background technique [0002] At present, domestic high-end passenger cars and heavy-duty commercial vehicles have begun to match pneumatic disc brakes, and with the improvement of the production technology of pneumatic disc brakes, their application in the transportation field is becoming more and more common. [0003] Floating caliper pneumatic disc brake is a kind of pneumatic disc brake. The sliding pin of the floating caliper pneumatic disc brake is fixed on the bracket, and the caliper body slides on the sliding pin. The sliding pin is a floating caliper pneumatic disc brake. It not only has the supporting function, but also plays a guiding role; and th...
