Problems solved by technology

However, the existing electromechanical braking system often lacks the function of automatic adjustment of the brake gap in the brake part, which causes the problem that the efficiency of the brake actuator changes indeterminately when the external environment changes and the friction lining is worn. Braking efficiency control brings certain difficulties
At the same time, most brakes have problems such as complex structure and large installation size.

Embodiment Construction

[0018] Reference attached figure 1 , an embodiment of the present invention will be described in detail.

[0019] Such as figure 1 As shown, an electromechanical brake by wire includes a brake caliper body (1), a brake disc (16) is arranged in the jaw of the brake caliper body (1), and friction plates are arranged on both sides of the brake disc (16). (15), one is mounted on the brake caliper body (1), the other is mounted on the piston (14), the piston (14) is mounted on the brake caliper body (1) through the sealing ring (13), and the sealing ring (13 ) and the contact surface of the piston (14) has a large friction force, when the displacement of the piston (14) is within the elastic deformation range of the sealing ring (13), the contact surface of the sealing ring (13) and the piston (14) There is no relative motion between them. The other side of the piston (14) is in direct contact with the cam (2), and the brake caliper body (1) is in direct contact with the cam (2)...

Abstract

The invention relates to an electronic and mechanical drive-by-wire brake. The electronic and mechanical drive-by-wire brake comprises a motor, a transmission mechanism, a one-way clutch, a cam, a piston, a friction limiting device and the like. The motor drives the one-way clutch to rotate through the transmission mechanism, the one-way clutch is united to drive the cam to move, the piston and a brake caliper body are driven to move in the opposite direction, friction plates are compressed with the same force from the two sides of a brake disc, and an efficient braking effect is achieved. The electronic and mechanical drive-by-wire brake is simple in structure, reliable in work and high in braking efficiency, and can automatically adjust the brake clearance, compensate the influence caused by friction plate wear, simplify the design of a control system and 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 an electromechanical 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 opti...
