Disc brake with floating calipers

Abstract

The invention discloses a disc brake with floating calipers, which comprises brake calipers and a brake disc, wherein a fixed brake block is arranged on the brake calipers; a first groove and an air inlet hole are formed in the surface, opposite to the fixed brake block, of the brake calipers; the air inlet hole is communicated with the first groove; the brake disc is located between the fixed brake block and the first groove; an air cylinder is arranged in the first groove; a piston which can stretch when the air cylinder is charged with air is arranged at the air cylinder; and the piston is in threaded connection with a movable brake block. The scheme has the beneficial effects as follows: the scheme adopts the air cylinder to replace a hydraulic system in a traditional brake, and at the time of braking, braking can be realized just by charging air into the air cylinder, so that the problems of sealing and brake fluid leakage of the traditional brake do not exist. Therefore, the brake adopting the scheme is simple in structure and high in reliability.

Description

technical field [0001] The invention relates to a disc brake, in particular to a floating caliper disc brake. Background technique [0002] Caliper disc brakes are a type of disc brakes. Its rotating element is a metal disc that works on the end face, called a brake disc, and the fixed element is a brake block composed of a friction block with a small working area and its metal back plate. These brake blocks and their actuating devices are installed In the clamp-shaped bracket spanning both sides of the brake disc, collectively called the brake caliper, the brake disc and the brake caliper together constitute the caliper disc brake. [0003] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. When the traditional floating caliper disc brake brakes, it relies on high-pressure brake fluid to push the piston, and the piston pushes the braking force. The moving block is pressed against ...

AI Technical Summary

Problems solved by technology

[0003] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. When the traditional floating caliper disc brake brakes, it relies on high-pressure brake fluid to push the piston, and the piston pushes the braking force. The moving block is pressed against the brake disc to achieve the braking effect. This hydraulic braking method requires a large amount of liquid, so a separate sealing structure needs to be designed during use. At the same time, if the sealing structure is not well done, it will Problems such as leakage of brake fluid occur, so that the structure of the brake becomes complicated and the reliability of the work is reduced
