Braking device of unmanned vehicle

Abstract

The invention relates to a braking device of an unmanned vehicle. The device comprises a motor, a reducer, a coder and a sensing mechanism, wherein the reducer is a worm gear reducer, the input end of the reducer is connected with the motor, and an output shaft at the back end of the motor is connected with the coder; one end of the output shaft of the reducer is connected with the contacts of sensors, the other end of the output shaft of the reducer is connected with a torque sensor, and the other end of the torque sensor is connected with a wire wheel wound with steel wires; and both sides of the upper part of a sensor fixing mount connected with the shell of the reducer are respectively provided with a zero-position sensor and a pole-position sensor, and the contacts of the two sensors are respectively positioned at the inner side of the circular motion trajectory of sensor contacts. In the invention, the worm gear mechanism can effectively keep a vehicle in the braking state; the spacing sensor and the torque limiter realize the effective braking and ensure the safety of the vehicle; and the steel wires avoid the interaction between the unmanned driving mode and the manual driving mode. The invention has the advantages of simple and compact structure, low cost and strong universality, and does not destruct the structure of the original vehicle.
