Automobile single-wheel device with independent steering and wheel-side drive and control method

Abstract

The invention relates to an automobile single-wheel device with independent steering and wheel-side drive and a control method. The car single wheel device includes steering motor, bogie, wheel drive motor and car single wheel, the steering motor is installed on the chassis of the car frame, the bogie is set under the chassis of the car frame, and the outer end of the bogie is provided with a flange , the output shaft of the steering motor is connected to the flange, the wheel drive motor is installed under the inner end of the bogie, and a transmission mechanism is connected between the output shaft of the wheel drive motor and the single wheel of the automobile. The control method is as follows: the driving of each single wheel of a car is independently controlled by its own wheel drive motor, and the steering of each single wheel of a car is independently controlled by its own steering motor, so that the car can realize crab driving, spot steering and oblique driving. The invention can accurately control the driving force of each wheel, flexibly adjust the steering angle of each wheel, greatly improve the steering stability and steering flexibility of the car, and has various driving modes, which is beneficial to alleviating traffic congestion.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile single-wheel device with independent steering and wheel-side drive and a control method. Background technique [0002] With the continuous development of the automobile industry, the number of vehicles continues to increase, and road resources are limited, so traffic congestion is becoming more and more serious. Improving the flexibility of vehicle operation is an effective way to alleviate traffic congestion. [0003] In the prior art, the vehicle drive method still uses a single engine or a single motor to provide a power source, which is transmitted to each drive wheel of the vehicle through a mechanical transmission system. Because there is only a single power source, the power distribution basically depends on the mechanical transmission mechanism, so it is impossible to accurately control the driving force of each wheel. In addition, the steering mode...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly solves the problem that the original steering mode of the automobile adopts the deflection of two front wheels in the same direction and the passive steering of the two rear wheels. Very low, it is easy to cause traffic accidents, and the power distribution basically depends on the mechanical transmission mechanism, so the technical problem of accurately controlling the driving force of each wheel cannot be achieved; provide an automobile single-wheel device with independent steering and wheel drive and control method, which can realize the independent driving and independent steering of each wheel of the automobile, so it can accurately control the driving force of each wheel, greatly improve the steering stability and steering flexibility of the automobile, and reduce the occurrence of traffic accidents

[0005] The present invention simultaneously solves the technical problems that the original driving mode of the automobile has always followed the traditional way and cannot be broken through, resulting in insufficient flexibility and limitations of the automobile driving, which is not conducive to alleviating traffic jams; it provides a vehicle with independent steering and wheel drive The single-wheel device and control method can realize the driving modes that cannot be realized by traditional cars, and the driving modes are diverse, flexible and less limited by space, which is conducive to alleviating traffic jams
