Floating caliper disc type brake

Abstract

The invention discloses a disc brake with floating caliper. The brake caliper is connected with the axle through a guide rod, and the brake caliper can slide on the guide rod relative to the brake disc; the brake caliper is erected on the brake disc in a C shape. On both sides; located on both sides of the disc body of the brake disc, two sets of brake friction plates are symmetrically installed on the brake caliper, one set of friction plates is connected to the piston; the caliper body of the brake caliper is provided with an oil chamber One end of the oil chamber is connected to the external oil input mechanism through the oil inlet; the piston is located at the other end of the oil chamber for hydraulic power output, and an inflatable air bag is also provided on the direct action surface between the piston and the oil. The inflatable air bag is filled with gas; there is also a return mechanism between the piston and the brake caliper; through the structural improvement of the existing floating caliper disc brake, it can have a fast braking response and can guarantee this The invented brake has good braking efficiency, simple structure and good performance, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of brakes, in particular to a floating caliper disc brake. Background technique [0002] A brake is a device that has the functions of slowing down, stopping or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or slows down moving parts in machinery, commonly known as brakes and brakes. The brake is mainly composed of frame, brake parts and operating device. Some brakes are also equipped with an automatic adjustment device for the clearance of the brake parts. In order to reduce the braking torque and structural size, the brakes are usually installed on the high-speed shaft of the equipment, but large equipment with higher safety requirements should be installed near the equipment. On the low-speed shaft of the working part. [0003] At present, friction brakes are mostly used in automobiles, which use the friction between the fixed element and the working surface...

AI Technical Summary

Problems solved by technology

[0004] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. The brake caliper of the floating caliper disc brake is floating and can move axially relative to the brake disc. During the braking process, the oil just needs to drive the entire brake caliper to move, which consumes a large amount of hydraulic pressure, the structure of the brake caliper is complex, the braking response is slow, and the braking efficiency is low. The floating caliper disc brake is difficult to adapt to modern vehicles. requirements for use
