Caliper body for pneumatic disc brake

Abstract

The invention relates to a caliper body for a pneumatic disc brake. The caliper body comprises a caliper main body formed by jointly connecting a box body section and a bridge frame section. A first mounting cavity is formed in the box body section, and a first bulge, a driving connecting plate, a second bulge and a connecting hole group are arranged on the box body section. The bridge frame section is provided with the second bulge, a third bulge, a first groove, a second groove and a fourth bulge. The box body section and the bridge frame section are connected in an arc-shaped transition mode. The caliper body structure has the advantages that a traditional caliper body structure is improved, and on the basis that the overall structural strength of the caliper body is met, the overall size of the caliper body is reduced as much as possible through mutual cooperation of different structures such as the bulge structures, the arc-shaped section structure, the groove structures and the arc-shaped transition connecting structure. Installation of the caliper body is facilitated, and the caliper body is prevented from interfering with installation of other parts of an automobile.

Description

technical field [0001] The invention relates to an automobile brake, in particular to a caliper body for an air pressure disc brake. Background technique [0002] Disc brakes have been widely used in cars, passenger cars and dangerous goods vehicles. Now most cars are used for all wheels, and a few cars are only used as front wheel brakes, which cooperate with rear wheel drum brakes to make the car have a higher braking force. Directional stability when moving. In commercial vehicles, disc brakes are now gradually being adopted in new and high-end models. [0003] There are air pressure disc brakes, which are controlled by air pressure. The main components include brake discs, air chambers, brake calipers, brackets, etc. The disc brake has fast heat dissipation, light weight, simple structure and convenient adjustment. Especially when the load is high, the high temperature resistance is good, the braking effect is stable, and it is not afraid of muddy water invasion. When...

AI Technical Summary

Problems solved by technology

[0006] The above two kinds of disc brakes all have certain defects: for the structure of the brake calipers, the outer surface of the brake calipers all adopts a single arc surface, which leads to the appearance of the entire brake calipers It will be relatively large, and the weight of the corresponding brake caliper will be relatively heavy. In addition, when the shape of the brake caliper is relatively large, the corresponding installation space will be relatively large, and in the actual installation During the process, the brake caliper will be affected by factors such as the installation space inside the car and the structure of adjacent components, resulting in a relatively small installation space for the brake caliper. In such a case, the brake caliper cannot be installed.
