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

[0019] Reference attached figure 1 And attached figure 2 , an embodiment of the present invention will be described in detail.

[0020] Such as figure 1 and figure 2 As shown, a floating caliper disc 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 guide flat key (10) and the sealing ring (9), and the guide flat key (10) makes the piston (11) only move along the axial direction , cannot rotate, there is a relatively large friction force between the contact surface of the sealing ring (9) and the piston (11), when the displacement of the piston (11) is within the elastic deformati...

Abstract

The invention relates to a floating clamp disc drive-by-wire brake comprising a motor, a transmission mechanism, a one-way clutch, a bi-directional nut, a left-handed screw, a right-handled screw, a piston, a friction limiting device and the like. The motor drives the outer circle of the one-way clutch to rotate through the transmission mechanism, the one-way clutch drives the bi-directional nut to rotate, and through a bi-directional thread mechanism, the piston and a braking clamp body are driven to move in the opposite directions correspondingly. A friction piece is tightly pressed from the two sides of a braking disc through the same force, and thus the efficient braking effect is achieved. According to the floating clamp disc drive-by-wire brake, the structure is simple, work is reliable, the braking efficiency is high, the braking gap can be automatically adjusted, the influence caused by friction piece abrasion is compensated, the design of a control system is simplified, and the floating clamp disc drive-by-wire brake can be used for travelling 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 a floating caliper disc type 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 ...
