Integrated brake caliper

Abstract

The invention provides an integrated brake caliper, and belongs to the technical field of vehicle braking. The integrated brake caliper comprises a brake support assembly provided with a friction plate structure and a brake shell connected with the brake support assembly; and a thrust assembly, an adjusting assembly and a piston are arranged in the brake shell. According to the integrated brake caliper, a limiting convex point and a limiting groove are arranged between the thrust assembly and the brake shell, and a connecting convex point and a connecting concave point are embedded and connected between the thrust assembly and the adjusting assembly, so that the layout space is reduced, the fit clearance is small, the parking endurance abrasion is small, the durability is better; meanwhile, a ball ramp structure and a multiple thread structure are adopted, so that the ejection effect of the piston is further improved, the mechanical transmission gap is shortened, and the braking performance is improved; the brake shell is a cast aluminum piece with reinforcing ribs, so that the weight is lighter; and the surface material of a silencing piece with a friction plate structure adoptsa rubber cloth ripple silencing piece so that the friction coefficient can be increased, the piston can be prevented from rotating, the parking performance is further improved, and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to an integrated brake caliper. Background technique [0002] The integrated brake calipers can brake the vehicle during driving and parking, and most of the rear brakes of passenger cars currently use integrated brake calipers, which are widely used in the market. [0003] The one-piece brake caliper is a disc brake. During the service braking, the hydraulic brake input is provided to the brake by stepping on the pedal. At this time, the brake and the brake disc are clamped, forcing the brake disc to stop rotating, thereby realizing the service braking function; When the parking brake is applied, the mechanical brake is used, the hand brake is pulled up and the cable is mechanically transmitted to the cable to tighten the cable, and then the cable drives the pull rod of the integrated brake caliper to rotate, and the interior of the integrated brake caliper makes the piston...

AI Technical Summary

Problems solved by technology

[0004] At present, due to the unreasonable structural design of the integrated brake calipers on the market, the mechanical transmission gap of the parts, the rigidity of the parts, the friction coefficient, etc. will cause serious loss during the mechanical transmission process inside the caliper, thereby reducing the At the same time, because the limit groove of the current integrated brake caliper is set on the cylinder wall of the housing, it takes up a lot of space and high production cost, and the structure adopts an integral cast iron structure, and the parts are heavy

These problems have led to the low market competitiveness of the existing one-piece brake calipers, which is not conducive to the development of the industry
