Electronic mechanical hydraulic wire control brake

Abstract

The invention relates to an electronic mechanical hydraulic wire control brake. The electronic mechanical hydraulic wire control brake comprises a motor, a transmission mechanism, a threaded mechanism, a large piston, a small piston, a hydraulic system and the like; the motor drives the threaded mechanism through the transmission mechanism, the hydraulic system is driven by the threaded mechanism,the large piston and a brake caliper body are driven to move in opposite directions through the hydraulic system, a friction plate is pressed by the same force from the two sides of a brake disc, andthe influence of hydraulic system failure and long-time continuous braking work can be avoided. The brake is simple in structure, reliable in work and high in braking efficiency, the braking clearance can be automatically adjusted, the influence caused by abrasion of the friction plate is compensated, the design of a control system is simplified, and the brake can be used for driving braking andparking 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. A wire-controlled mechanical brake with adjustable braking strength, especially an electro-mechanical hydraulic 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 ...

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. Braking efficiency control brings certain difficulties

At the same time, because the mechanical transmission parts need to achieve a large transmission ratio, they often have large dimensions and high space requirements, so most brakes have problems such as relatively complex structures and large installation dimensions.
