Problems solved by technology

The free gap of the disc brake is very small, when the contact between the friction plate and the brake disc occurs due to impurities, unevenness and other reasons, due to the self-energizing characteristics of the wedge mechanism, it is easy to cause wrong braking

Embodiment Construction

[0026] Reference attached figure 1 And attached figure 2 , an embodiment of the present invention will be described in detail.

[0027] Such as figure 1 As shown, a self-energizing brake-by-wire includes a brake caliper body 3 that can move on a guide pin 2 , and the guide pin 2 is fixed on a brake caliper bracket 1 . There is a brake disc 13 in the jaw of the brake caliper body 3, and there are friction plates 12 on both sides of the brake disc 13, one is installed on the brake caliper body 3, and the other is installed on the large piston 29, and the large piston 29 passes through the cone The snap ring 28 is installed on the brake caliper body 3 , and the truncated cone snap ring 28 is pushed to the side away from the brake disc 13 by the oblique spring 27 , and the oblique spring 27 is installed on the brake caliper body 3 . There is a relatively large frictional force between the contact surface of the truncated cone snap ring 28 and the large piston 29. When the disp...

Abstract

The invention relates to a self-energizing wire-controlled brake, which includes a motor, a transmission mechanism, a one-way clutch, a screw mechanism, a large piston, a small piston, an elastic positioning device and the like. The motor drives the one-way clutch to rotate through the transmission mechanism, and the one-way clutch drives the threaded mechanism, which drives the large piston and the brake caliper body to move in opposite directions respectively, and presses the friction plate with the same force from both sides of the brake disc. To achieve efficient self-boosting braking effect, while avoiding erroneous autonomous braking caused by other factors. The invention has the advantages of simple structure, reliable operation, high braking efficiency, automatic adjustment of the braking gap, compensation for the influence caused by friction plate wear, simplified design of the control system, and can be used for driving 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...
