Self-boosting wire-controlled brake

Abstract

The invention discloses a self-boosting wire-controlled brake. The self-boosting wire-controlled brake comprises a motor, a transmission mechanism, a one-way clutch, a cam, a large piston, a small piston, an elastic positioning device and the like, wherein the motor drives the one-way clutch to rotate through the transmission mechanism, the one-way clutch is engaged to drive the cam to move, the large piston and a brake caliper body are driven to move in opposite directions, and friction plates are tightly pressed by the same force from the two sides of a brake disc, so that the high-efficiency self-boosting brake effect is achieved, and wrong autonomous braking caused by other factors is avoided at the same time. According to the self-boosting wire-controlled brake, the structure is simple, the work is reliable, the braking efficiency is high, the brake clearance can be automatically adjusted, the influence caused by abrasion of the friction plates can be compensated, the design of the control system is simplified, and the self-boosting wire-controlled brake can be applied to driving braking and parking braking.

Description

technical field [0001] The invention relates to the field of brakes, in particular, it can replace the existing floating caliper disc hydraulic brakes, realize friction discs clamping the brake discs from both sides with the same pressure in an electronically controlled manner, and at the same time realize adjustable brake clearances , a wire-controlled mechanical brake with adjustable braking strength, in particular a self-energizing wire-controlled brake. Background technique [0002] Brake-by-wire technology is a new type of braking technology that has emerged in recent years. It does not rely on mechanical or hydraulic connections between the brake and the brake pedal. The control system receives the information from the sensor to control the motor to work. Stable and reliable brake control. At present, there are mainly two types of electronic hydraulic braking system (EHB) and electromechanical braking system (EMB). The brake-by-wire system is conducive to the optimiz...
