Disc brake structure

Abstract

The utility model discloses a disc brake structure, which belongs to the technical field of disc brakes. A releasing cylinder and a spring chamber are respectively arranged at two ends of a cylinder body; a braking cylinder is arranged on the end surface of the cylinder body at one end where the spring chamber is also arranged; a piston is installed in the releasing cylinder; a guide rod penetrates through middle holes of the spring chamber and the releasing cylinder; one end of the guide rod is connected with the piston; a fastening bolt penetrates through the piston and the guide rod in sequence and then is connected and fixed with a brake body into a whole body; a spring seat is installed in the spring chamber; a belleville spring is installed on the spring seat; the belleville spring compresses the brake body; an annular piston is installed in the braking cylinder; a friction disk is fixed at the outer end of the brake body; a fixing bracket is installed at the end part of the cylinder body; and a magnetic induction type sensor is installed at the center of the bracket. The disc brake structure has the advantages of simple structure, reliability in operation and intellectualization.

Description

technical field [0001] The invention relates to a disc brake structure, belonging to the technical field of disc brake structures. Background technique [0002] Disc brakes are widely used in deceleration braking and parking of mine hoists, large traction winches, and hoisting and transporting machinery; and emergency braking under safety conditions. At present, disc brakes used in the above fields have a structural There are relatively complex and high failure rate defects. At the same time, due to structural reasons, the braking force of this type of brake is provided by the brake spring. During the process of releasing the brake, the hydraulic cylinder pushes the piston. , Compress the brake spring to achieve the purpose of releasing the brake. Because the brake spring is used for a long time, it is prone to fatigue and damage; therefore, it is easy to reduce the braking effect, and even brake failure will occur, resulting in safety accidents In addition, this kind of br...

[0002] Disc brakes are widely used in deceleration braking and parking of mine hoists, large traction winches, and hoisting and transporting machinery; and emergency braking under safety conditions. At present, disc brakes used in the above fields have a structural There are relatively complex and high failure rate defects. At the same time, due to structural reasons, the braking force of this type of brake is provided by the brake spring. During the process of releasing the brake, the hydraulic cylinder pushes the piston. , Compress the brake spring to achieve the purpose of releasing the brake. Because the brake spring is used for a long time, it is prone to fatigue and damage; therefore, it is easy to reduce the braking effect, and even brake failure will occur, resulting in safety accidents In addition, this kind of brake has the defect of poor intelligence because it cannot monitor the braking and release status
