Abstract

The invention relates to a speed adjusting device for front and rear wheels of an intelligent automobile, the speed adjusting device comprises a driving motor and a reduction gear box, the reduction gear box comprises an input gear and an output gear which are connected with each other, and the speed adjusting device for the front and rear wheels further comprises a position sensor arranged on a transmission shaft of the output gear; an output shaft of the driving motor is connected with the input gear; the output gear is provided with a spline groove connected with a connecting shaft of an automobile differential mechanism. Wherein the position sensor is used for detecting the running state of the output gear and feeding back the collected speed information of the front wheel and the rear wheel to an automobile central control system, and the automobile central control system judges whether a normally-driven engine is switched to the speed adjusting device for the front wheel and the rear wheel or not. The driving motor adjusts the speed of the front and rear wheels through the reduction gear box so as to ensure that the speed of the front and rear wheels of the automobile is the same.

Description

technical field [0001] The invention relates to the technical field of wheel speed adjustment of an intelligent automobile, in particular to a front and rear wheel speed adjustment device of an intelligent automobile. Background technique [0002] As society pays more and more attention to energy and the environment, the traditional automobile industry is developing towards green and environmentally friendly new energy vehicles. Compared with the motors of traditional automobiles, the stepper motors of new energy vehicles have the advantages of compact structure, small size, independent controllable driving mode, and high power density. The stepper motor of the new energy vehicle can simplify the chassis structure of the new energy vehicle, and at the same time increase the flexibility of the power switching of the new energy vehicle. [0003] The gear type transfer motor has been widely used in all kinds of all-wheel drive vehicles, but it cannot guarantee that the speeds ...
