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 of the brakes have problems such as complex structure and large installation size.

Embodiment Construction

[0020] Reference attached figure 1 And attached figure 2 , an embodiment of the present invention will be described in detail.

[0021] 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 the 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 deforma...

Abstract

The invention relates to a floating caliper disc type line control brake and a control method. The floating caliper disc type line control brake comprises a motor, a transmission mechanism, a one-way clutch, a nut, a threaded rod, a piston, a friction limiting device and the like. The motor drives an outer ring of the one-way clutch to rotate through the transmission mechanism. The one-way clutch drives the nut to rotate. The piston and a pair of brake calipers are driven to move in the opposite direction through a thread transmission mechanism correspondingly. Friction pieces are pressed by the same force from the two sides of a braking disc, and the efficient braking effect is achieved. The floating caliper disc type line control brake is simple in structure, reliable in working and high in braking efficiency, braking gaps can be automatically adjusted, the influence caused by abrasion of the friction pieces is compensated, the design of a control system is simplified, and the floating caliper disc type line control brake 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 The invention relates to a wire-controlled mechanical brake with adjustable braking strength, in particular to a floating caliper disc type wire-controlled brake and a control method. 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 (E...
