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

Abstract

The invention discloses a commercial vehicle disc brake caliper body assembly with a ventilation self-adjusting structure, which includes a support sleeve, a short bush, a short pin, a skeleton oil seal and a plastic dust cover. The brake caliper body A brake bracket is installed on the outer side of the brake caliper body, and a pin shaft is installed on the middle side of the brake caliper body; the invention facilitates increasing the sliding stroke of the short pin, increasing the wear resistance of the short bushing and better guiding , easy to install, improved waterproof and dustproof function, the bottom of the gasket and the body of the brake caliper are more closely and reliably matched, the sealing effect is improved, and the problem of water leakage and water seepage is completely solved; the working performance of the adjustment mechanism is improved, and the cooperation and coordination of internal parts are strengthened. Working stability overcomes many problems such as uneven braking force, clearance adjustment failure, adjustment mechanism deformation, braking failure and many other problems that may occur during the braking process, and can well play the self-locking function of the threaded adjustment sleeve.

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...

[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.
