Electro-mechanical hydraulic line control brake

Abstract

The invention relates to an electro-mechanical hydraulic line control brake which comprises a motor, a transmission mechanism, a gear, racks, a piston, a hydraulic system and other parts. The motor drives the gear to rotate through the transmission mechanism; a rack and pinion mechanism and the hydraulic system respectively drive the piston and a brake caliper body to move in opposite directions,and friction plates are pressed from two sides of a brake disc with the same force, thereby avoiding hydraulic system failure and possible effects caused by prolonged braking operation. The electro-mechanical hydraulic line control brake provided by the invention is simple in structure, reliable to work and high in braking efficiency, is capable of automatically adjusting the brake clearance, compensating for the influence caused by wear of the friction plates and simplifying the design of a control system, and 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 plates clamping the brake discs from both sides with the same pressure in an electro-mechanical hydraulic manner, and at the same time realize adjustable brake clearances. Adjustable, brake-by-wire brake with adjustable braking strength, especially an electromechanical hydraulic brake-by-wire. 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 optim...

AI Technical Summary

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. Brakin...
