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 And attached figure 2 , 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 (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...

Abstract

The invention relates to an electromechanical brake by wire. The electromechanical brake by wire comprises a motor, a transmission mechanism, a one-way clutch, a threaded rod, a nut, 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 drives the nut to rotate in a combined mode, the piston and a brake caliper body are driven to move in the opposite directions through a thread transmission mechanism, friction plates are compressed with identical force from both sides of a brake disc, and an efficient braking effect is achieved. According to the electromechanical brake by wire, the structure is simple, work is reliable, the braking efficiency is high, brake clearance can be automatically adjusted, the influence caused by abrasion of the friction plates is compensated for, the design of a control system is simplified, and the electromechanical brake by wire 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 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...
