Abstract

The invention discloses a rear wheel steering driving mechanism for an electric racing car and the electric racing car. A motor of the rear wheel steering driving mechanism is arranged at one end of amotor supporting seat, and a second gear is arranged on a rotating shaft of the motor; an encoder is arranged at one end of an encoder supporting seat, and an encoder synchronous pulley is arranged on an output shaft of the encoder; a first gear is connected with a lead screw in a threaded mode, and a lead screw synchronous pulley and the first gear are fixed; the two ends of the lead screw are rotatably connected with the two supporting seats; and the first gear meshes with the second gear, and the lead screw synchronous pulley is connected with the encoder synchronous pulley through a conveyor belt. The rotating shaft of the motor sequentially drives the second gear, the first gear, the lead screw, the lead screw synchronous pulley, the encoder synchronous pulley, and the output shaft of the encoder to rotate, data acquisition of the encoder is realized, rotating angle data of the first gear can be calculated according to the collected data, accurate control over the rear wheel steering is realized, the dynamic response is realized, and the problem that in the prior art, a rear wheel driving mechanism cannot realize the dynamic response is solved.

Description

technical field [0001] The present application relates to the technical field of electric racing cars, in particular to a rear wheel steering drive mechanism for electric racing cars and the electric racing cars. Background technique [0002] With the increasingly complex modern traffic system and the continuous development of automobile technology, the active safety of automobiles has been paid more and more attention, especially the advanced active chassis control technology is an important direction of automobile development. [0003] Front-wheel steering has been the primary way cars have been turned since the invention of the car. However, front-wheel steering vehicles have inherent defects: slow steering response at low speeds, large turning radius, and heavy steering; poor steering stability at high speeds, and difficulty in overtaking and changing lanes. Especially with the increase of cars, the parking space in the community is becoming more and more crowded, and t...
