Automobile disc brake with extrusion shifting type auxiliary braking structure

Abstract

The invention provides an automobile disc brake with an extrusion shifting type auxiliary braking structure, and relates to the technical field of disc brakes. The automobile disc brake solves the problems that when an existing disc brake is applied to braking, hydraulic driving is mostly adopted for achieving braking limiting of a friction gasket and a braking disc, however, the braking time is too long due to the fact that braking limiting is not stable only through friction limiting between the unidirectional friction gasket and the braking disc. The automobile disc brake with the extrusion shifting type auxiliary braking structure comprises a disc brake body and an extrusion driving mechanism, and the extrusion driving mechanism is connected with the disc brake body in a sliding mode. According to the disc brake, through cooperation of the extrusion driving mechanism, an extrusion shifting piece and an extrusion braking mechanism, the extrusion shifting piece is meshed to shift the extrusion braking mechanism to move in the opposite direction, so that a friction gasket B and a friction gasket A jointly extrude and limit the braking disc, the auxiliary braking effect is achieved, and it is guaranteed that the braking effect of the disc brake is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of disc brakes, and more specifically relates to an automobile disc brake with a squeezing and toggle auxiliary braking structure. Background technique [0002] Disc brakes are brake systems that use metal blocks (discs) instead of drums. Disc brakes have a flat brake shoe on both sides of the brake disc. When the oil pressure of the brake master cylinder is sent to the sub-cylinder, the brake shoe is clamped to the brake disc to achieve the effect of braking. [0003] For example, application number: CN201110228459.3 The present invention discloses an electromagnetic disc brake with an anti-friction device, including a stator housing, a coil, an armature, a fixed pin shaft, and two sets of friction plate assemblies; the present invention also includes a friction plate and a fixed The bracket, the friction plate is connected with the stator housing through the friction plate connecting screw and the bushing...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an automobile disc brake with a squeeze-and-dial auxiliary braking structure to solve the problem that the existing disc brakes mostly use hydraulic drive to realize friction pads when braking. The braking limit with the brake disc, but only through the friction limit between the friction pad and the brake disc in one direction, the braking limit is not stable, and there is a problem that the braking time is too long
