Steering system

Abstract

The invention discloses a steering system. The invention belongs to the technical field of automobile steering. The steering system comprises a first transmission device connected with a first steering wheel, a first driving motor connected with the first transmission device, a second transmission device connected with a second steering wheel, a second driving motor connected with the second transmission device, and a control unit electrically connected with the first driving motor and the second driving motor and used for controlling the steering of the first steering wheel and the second steering wheel by controlling the rotation of the first driving motor and the second driving motor. The steering system has the advantages that the two steering wheels are independently controlled, eachsteering wheel is controlled to deflect according to the optimal deflection angle, it is guaranteed that the instantaneous speed center of the rear wheels intersects with the instantaneous speed center of the two front wheels in the automobile steering process, relative sliding between tires and the ground is reduced or even eliminated, and the steering precision and safety of an automobile are improved.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a steering system. Background technique [0002] In the process of driving, the car needs to change the direction frequently. The change of the driving direction of the car is realized by changing the deflection angle of the steering wheel. A complete set of parts and control devices that control the deflection angle of the steering wheel is called the automobile steering system. The safety and reliability of the automobile steering system is the key to realizing intelligence. In addition to achieving precise steering, a high-precision steering system can also input path data into the control system in advance to effectively reduce the amount of environmental data collected. Shorten the time for data processing, and finally achieve the goal of stable, fast and accurate control system. [0003] The steering gear used in the automobile steering system in the prior art ...

AI Technical Summary

Problems solved by technology

[0004] However, due to the constraints of the link mechanism between the two steering wheels, it is difficult for the instantaneous velocity centers of the two steering wheels to meet at point A, as in figure 1 As shown by the middle line b, under normal circumstances, the instantaneous velocity center of the rear wheel does not meet the instantaneous velocity center of the two front wheels, which will cause relative slippage between the tire and the ground, which will lead to a decrease in the steering accuracy and safety of the car , in the prior art, optimization of the geometric dimensions of the linkage mechanism is usually used to improve the steering accuracy. However, due to the limitation of the objective conditions of the linkage mechanism, the effect of optimization is limited.
