Wedge-shaped self-power-increasing disc brake

Abstract

The invention discloses a wedge-shaped self-power-increasing disc brake which comprises a brake caliper body, a wedge-shaped brake block, friction linings, a fixed brake block, 4-6 rollers, a seal ring, a wheel cylinder piston, a wheel cylinder, two baffle plates and a brake caliper guide frame, wherein the upper end of the brake caliper body and an upper brake caliper opening in the brake caliper guide frame are assembled; the inner side surfaces of the brake caliper openings in the brake caliper body are connected with the 4-6 rollers in a contacted mode; the 4-6 rollers and the large right-angle side surface of the wedge-shaped brake block positioned below are connected in a contacted mode; the friction lining is pasted on the beveled edge surface of the wedge-shaped brake block; and the small right-angle side surface of the wedge-shaped brake block is connected with the extending end of the wheel cylinder piston; the seal ring is installed between the wheel cylinder piston and thewheel cylinder; the fixed brake block is fixed on a lower brake caliper opening in the brake caliper guide frame; the second friction lining is pasted on the fixed brake block; the two baffle plates are installed on two end surfaces of the brake caliper openings in the brake caliper body through a bolt; and inner end surfaces of the two baffle plates and two end surfaces of the wedge-shaped brakeblock are in clearance fit.

Description

technical field [0001] The present invention relates to a braking device for automobiles, more precisely, the present invention relates to a new wedge-shaped self-energizing disc brake based on a conventional hydraulic actuation system. Background technique [0002] The brake is a component in the braking system that decelerates the car to a safe speed with an appropriate deceleration or until it stops, or keeps the car at an appropriate and stable speed when driving downhill, or makes the car reliably stop at the original position. At present, brakes are mainly divided into drum brakes and disc brakes structurally. Self-energizing brakes are generally drum brakes, while disc brakes are almost non-existent at present. Because there is no self-energizing effect, the braking efficiency of the disc brake is low. Therefore, the hydraulic disc brake currently used must be equipped with a booster in the system, and when the hydraulic actuating device is used to provide the actuat...

Problems solved by technology

However, the complexity of the structure, high requirements for control, high cost, and the dynamic response of the motor are issues that need to be considered for this type of electromechanical brake. In addition, the motor is directly installed on the brake, and the motor caused by the working environment and vibration Reliability issues also need to be considered in engineering design
