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

[0028] Reference attached figure 1 , an embodiment of the present invention is described in detail.

[0029] like figure 1 As shown, an electromechanical wire-controlled brake with more stable transmission characteristics includes a brake caliper body (3) that can move on a guide pin (2), which is fixed on a brake caliper bracket (1) . There are brake discs (16) in the jaws of the brake caliper body (3), friction plates (15) are arranged on both sides of the brake disc (16), one is mounted on the brake caliper body (3), the other is mounted on the piston (14), the piston (14) is mounted on the brake caliper body (3) through the sealing ring (13), and there is a large frictional force between the contact surface of the sealing ring (13) and the piston (14). When the displacement of 14) is within the elastic deformation range of the sealing ring (13), there is no relative movement between the contact surfaces of the sealing ring (13) and the piston (14). The other side of th...

Abstract

The invention relates to an electronic mechanical drive-by-wire brake with more stable transmission characteristics. The electronic mechanical drive-by-wire brake comprises a motor, a transmission mechanism, a bidirectional nut, a left-handed screw, a right-handed screw, a piston, a connecting rod with a wedge-shaped adjusting mechanism, a friction limiting device and the like. The motor drives the two-way nut to rotate through the transmission mechanism, the connecting rod is driven to move through the two-way nut screw transmission mechanism, the piston and the brake caliper body are driven to move in the opposite directions, the friction plate is pressed tightly from the two sides of the brake disc with the same force, and the efficient brake effect is achieved. The brake device is simple in structure, reliable in work, high in brake efficiency and capable of automatically adjusting the brake clearance, compensating influences caused by friction plate abrasion and simplifying the design of a control system, and can be used for traveling brake and parking brake.

Description

[0001] This application is a divisional application, the application number of the original invention application on which it is based is: 201810024791X, the application date is: January 3, 2018, and the original application name: an electronic mechanical wire controller. technical field [0002] The invention relates to the field of brakes, in particular, it can replace the existing floating caliper disc hydraulic brake, realizes that the friction plate clamps the brake disc with the same pressure from both sides in an electronically controlled mechanical manner, and can realize adjustable braking clearance at the same time , a wire-controlled mechanical brake with adjustable braking strength, especially an electronic mechanical wire-controlled brake. Background technique [0003] Brake-by-wire technology is a new type of braking technology that has appeared in recent years. It does not rely on mechanical or hydraulic connection between the brake and the brake pedal. stable...
