Abstract

Disclosed is an anti-lock braking system which mainly comprises a driving unit and a hydraulic unit, the driving unit is in transmission connection with the hydraulic unit through a screw, the hydraulic unit comprises a piston and a piston cylinder, the piston cylinder is provided with at least three connectors in the moving direction of the head of the piston, and the connectors are not located on the same radial section of the piston cylinder. The driving unit comprises a motor and a planetary gear mechanism, the planetary gear mechanism comprises a planet carrier, a sun gear and an inner gear, the outer side of the planet carrier is connected with a screw in the axis direction of the planet carrier, the planet carrier is in threaded connection with the skirt portion of the piston through the screw, the motor drives the screw to rotate, and the piston in threaded connection with the outer side of the screw moves. The space of the piston and the space of the inner cavity of the piston cylinder are changed, the pressure intensity in the cavity is changed, and the flowing direction of brake fluid is changed, so that the storage amount of the brake fluid at the brake wheel is reduced, the brake pressure of the wheel cylinder is reduced, and anti-lock at the brake wheel is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile braking devices, and in particular relates to an anti-lock braking system. Background technique [0002] With the continuous development of new energy technologies, new energy motorcycles and new energy electric bicycles have developed rapidly. The wide application of new energy electric bicycles can largely alleviate environmental pollution and energy crises. [0003] The vehicle safety control system represented by the anti-lock brake control system has been widely used in automobiles. In recent years, with the continuous improvement of living conditions and the continuous improvement of the traffic operating environment, the sales volume of new energy electric bicycles and new energy motorcycles has increased significantly. The number of holdings is getting higher and higher, and the corresponding call for improving the safety performance of new energy electric bicycles and new energy motorc...
