Floating caliper disc type brake

Abstract

The invention discloses a floating caliper disc type brake. A brake caliper is connected with an axle through a guide rod, and the brake caliper can slide on the guide rod relative to a brake disc. The brake caliper is erected at the two sides of the brake disc in a C form. At the two sides of the disc body of the brake disc, two groups of brake friction pads are separately symmetrically mounted on the brake caliper, and one group of friction pads is connected to a piston. An oil cavity is arranged in the caliper body of the brake caliper, and one end of the oil cavity is connected with an outer oil input mechanism through an oil inlet. The piston is located at the other end of the oil cavity and used for hydraulic power output. An inflatable air bag is further arranged on the direct acting surface of the piston with oil, and the inflatable air bag is filled with air. A resetting return mechanism is further arranged between the piston and the brake caliper. Through the structural improvement of the existing floating caliper disc type brake, the floating caliper disc type brake can have rapid brake reaction, and the brake of the invention is simple in structure, great in use performance and suitable for popularization and application under the condition of having great brake efficiency.

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
