Abstract

The invention discloses a brake-by-wire device for a driverless racing car. The brake-by-wire device for the driverless racing car comprises a brake motor, a reducer, a driving rocker arm, a right angle pulling rod and a driving pilling plate lifting lug, wherein the reducer is fixedly connected with an output shaft of the brake motor, and two baffles are arranged near the circumference of an output shaft of the reducer in an opposite mode; one end of the driving rocker arm is fixedly connected with the output shaft of the reducer, a circular through hole is formed in the upper end of the driving rocker arm, and two grooves are formed in the inner wall of the through hole along the circumference in an opposite mode; the baffles are matched with the grooves in an opposite mode; one end of the right angle pulling rod is hinged to the other end of the driving rocker arm; and one end of the driving pulling plate lifting lug is hinged to the other end of the right angle pulling rod, and theother end of the driving pilling plate lifting lug is hinged to the upper end of a brake pedal. According to the brake-by-wire device for the driverless racing car, under the premise of braking reliability, the brake and the unmanned brake do not interfere with each other.

Description

technical field [0001] The invention relates to the technical field of an unmanned racing car, in particular to a braking system for an unmanned racing car. Background technique [0002] Unmanned driving has emerged under the development of intelligent technology and interconnection technology. In order to promote the cultivation of talents in my country's automobile industry, college students have modified the original electric racing car to study the technology of unmanned racing car. The competition requires that the driver can drive. Realize unmanned driving and participate in the student formula competition. The wire-control modification of the braking system is an important part of it. The existing unmanned racing car braking mainly adopts adding a cable in front of the brake pedal. The cable is wound around the output shaft of the motor, and the motor rotates to drive the pull The cable pulls the brake pedal to rotate for braking. However, this braking mode has poor ...
