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

[0025] Reference attached figure 1 And attached figure 2 , an embodiment of the present invention is described in detail.

[0026] Such as figure 1As shown, an electromechanical 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 discs (12) on both sides of the brake disc (13), one is mounted on the brake caliper body (3), and the other is mounted on the piston (11), the piston (11) is installed on the brake caliper body (3) through the sealing ring (9), and there is a relatively large friction force between the contact surface of the sealing ring (9) and the piston (11), when the piston ( 11) When the displacement is within the elastic deformation range of the sealing ring (9), there is no relative movement between the contact surfaces of the sealing ring (9) and the piston (11). The other...

Abstract

The invention relates to an electronic machinery wire control brake which comprises a motor, a transmission mechanism, a screw rod with a wedge-shaped adjusting mechanism, a nut, a piston, a friction limiting device and the like. The screw rod is matched with the nut; a motor drives a screw rod nut component to rotate through a transmission mechanism; a piston and a brake caliper body are driven to move oppositely through a screw rod nut transmission pair; a friction plate is compressed with the same force and from the two sides of a brake disc to realize an efficient brake effect. The electronic machinery wire control brake provided by the invention has the advantages of simple structure, reliable work and high brake efficiency, and can automatically adjust the brake clearance and compensate for the influence caused by the wear of the friction plate; the design of the control system is simplified, and the electronic machinery wire control brake can be applied to service brake and parking brake.

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...
