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

[0021] Reference attached figure 1 , an embodiment of the present invention will be described in detail.

[0022] Such as figure 1 As shown, a self-energizing wire-controlled brake includes a brake caliper body 1, a brake disc 16 is arranged in the jaw of the brake caliper body 1, and there are friction plates 15 on both sides of the brake disc 16, one of which is mounted on the brake On the caliper body 1, one is installed on the large piston 4, and the large piston 4 is mounted on the brake caliper body 1 through the large sealing ring 13. There is a relatively large friction force between the large sealing ring 13 and the contact surface of the large piston 4. When the displacement of the large piston 4 is within the elastic deformation range of the large sealing ring 13 , there is no relative movement between the contact surfaces of the large sealing ring 13 and the large piston 4 . The other end of the large piston 4 has an inclined surface, which is installed in cooper...

Abstract

The invention relates to a self-energizing effort drive-by-wire brake. The self-energizing effort drive-by-wire brake comprises a motor, a transmission mechanism, a one-way clutch, a rotary rod, a connecting rod, a large piston, a small piston, an elastic locating device and the like. The one-way clutch is driven to rotate by a motor through the transmission mechanism, the one-way clutch is combined with and drives the rotary rod to move, the connecting rod is driven to move through motion of the rotary rod, the large piston and brake calipers are driven to move toward the opposite direction,a friction plate is tightly pressed with the same force from the two sides of a brake disc, the efficient self-energizing effort braking effect is achieved, and meanwhile false autonomous braking caused by other factors is avoided. According to the self-energizing effort drive-by-wire brake, the structure is simple, working is reliable, the braking efficiency is high, the brake clearance can be automatically adjusted, the influence caused by friction plate abrasion is compensated, design of a control system is simplified, and the self-energizing effort drive-by-wire brake can be used for service 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...
