Commercial vehicle disc brake caliper assembly with ventilation and self-adjusting structure

Abstract

The invention discloses a commercial vehicle disc brake caliper assembly with a ventilation and self-adjusting structure. The commercial vehicle disc brake caliper assembly comprises a supporting sleeve, a short bushing, a short pin, a skeleton oil seal and a plastic dust cover; a brake support is mounted on the outer side of a brake caliper body; and a pin shaft is mounted on the middle side inside the brake caliper body. Increasing of the sliding stroke of the short pin is facilitated, the abrasion resistance and better guidance performance of the short bushing can be improved easily, mounting is easy, and the waterproof and dustproof functions are promoted; the bottom of a sealing cushion and the brake caliper body are matched more tightly and more reliably, the sealing effect is promoted, and the water leakage and water seepage problems are solved thoroughly; and the working performance of an adjusting mechanism is promoted, matching and working stability of internal parts are strengthened, the multiple problems such as nonuniform braking force, failure in clearance adjustment, deformation of the adjusting mechanism and braking failure in the braking process are solved, and thefunction of self-locking of a thread adjusting sleeve can be well achieved.

Description

technical field [0001] The invention relates to the technical field of a commercial vehicle disc brake caliper body assembly, in particular to a commercial vehicle disc brake caliper body assembly with a ventilation self-adjusting structure. Background technique [0002] The existing commercial vehicle disc brake caliper body assembly has the following disadvantages: the dustproof plate is a stamping part, because this position is a stressed part, repeated braking impacts, it is easy to deform it, resulting in seal failure In serious cases, the stamping dustproof plate breaks, etc., and there are hidden dangers of braking. The original support seat dustproof cover only has a dustproof effect, and the spring structure is complex from the adjustment structure. Long-term work will make the spring prone to fatigue and affect the service life. One-way bearings The main adjustment of the structure has a short service life, prone to functional failure and difficult parts processing...

Problems solved by technology

[0002] The existing commercial vehicle disc brake caliper body assembly has the following disadvantages: the dustproof plate is a stamping part, because this position is a stressed part, repeated braking impacts, it is easy to deform it, resulting in seal failure In serious cases, the stamping dustproof plate breaks, etc., and there are hidden dangers of braking. The original support seat dustproof cover only has a dustproof effect, and the spring structure is complex from the adjustment structure. Long-term work will make the spring prone to fatigue and affect the service life. One-way bearings The service life of the main adjustment of the structure is short, it is prone to function failure and the processing of parts is difficult, uneven braking force, clearance adjustment failure, adjustment mechanism deformation, braking failure and many other problems will occur during the braking process.
