Abstract

The present invention is one electric stopping brake assistor for hand stopping brake system of automobile with braking handle. The electric stopping brake assistor consists of an assisting motor, a clutch, a planetary speed reducing mechanism, an angle sensor, and an electronic control unit with built-in first set angle and second set angle. The assisting motor has its output shaft connected through the clutch to the planetary speed reducing mechanism; the planetary speed reducing mechanism has its output shaft connected through a coupling to the rotation shaft of the braking handle in the hand stopping brake system and one angle sensor connected for detecting the rotation angle of the handle, and the assisting motor and the angle sensor are connected electrically to the electronic control unit. The electric stopping brake assistor has simple structure and capacity of assisting the driver's stopping.

Description

technical field [0001] The invention relates to an automobile parking brake device, in particular to an automobile parking brake electric booster device which has a simple structure and can provide power assistance for the driver's parking brake. Background technique [0002] At present, what the parking brake system of existing car adopted is manual parking brake joystick. When parking brake, pull up the joystick, the joystick drives the cable system, and the cable system makes the disc (or drum) brake of the rear wheel lock the tire, thereby realizing the parking brake function. Specifically, please refer to the CN89216395 patent of China. However, the joystick of this structure has certain requirements on the driver's hand strength. If the driver's strength is relatively small (such as a female driver), it is possible that the joystick cannot be pulled in place due to insufficient strength, resulting in failure to effectively reach the parking position. The braking effe...
