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

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

[0022] 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 piston (14) has rotating rod (2), and connecting rod (6) hinge connects one end of rotating rod (2) and piston (14) and the...

Abstract

The invention relates to an electronic mechanical wire control brake which comprises a motor, a transmission mechanism, a connecting rod, a rotating rod, a piston, a friction limiting device and the like. The connecting rod is provided with a wedge-shaped adjusting mechanism. The motor drives the rotating rod to move through the transmission mechanism. The rotating rod moves to drive the connecting rod provided with the wedge-shaped adjusting mechanism to move, the piston and brake calipers are driven to move to the opposite direction, friction pads are pressed with the same force from the twosides of a braking disc, and the efficient braking effect is achieved. The brake is simple in structure, reliable in work and high in braking efficiency, the braking gap can be adjusted automatically, the influence caused by abrasion of the friction pads is compensated, the design of a control system is simplified, and the brake can be used for traveling 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...
