Problems solved by technology

[0002] In narrow road conditions, the in-situ steering function of the vehicle can improve the passability of the vehicle. In the related technology, the four-wheel steering of the vehicle is mainly to set a hydraulic system on each of the four wheels, and drive each wheel through the hydraulic system. This method involves more oil circuits and takes up a lot of space in the vehicle. The steering fluid is twice as much as that of ordinary hydraulic steering vehicles, which is easy to pollute the environment, and the hysteresis time of hydraulic drive is long, and the operating experience is poor. There is room for improvement.

Abstract

The invention discloses a steering system and a vehicle. The steering system comprises a front transverse pull rod connected with a front wheel, a front steering gear connected with the front transverse pull rod, a front assistance module, a rear transverse pull rod connected with a rear wheel, a rear steering gear connected with the rear transverse pull rod and a rear assistance module, wherein the front assistance module is installed on the front transverse pull rod and arranged to selectively provide transverse assistance and longitudinal assistance, and the rear assistance module is installed on the rear steering gear and arranged to selectively provide transverse assistance and longitudinal assistance. According to the steering system, the two-degree-of-freedom assistance modules areintegrated on the front steering gear and the rear steering gear respectively, various steering modes including steering in place and four-wheel steering can be achieved, the distance between the front assistance module and the wheels and the distance between the rear assistance module and the wheels are small, and a control instruction is rapidly and accurately controlled to make response, and the operability is higher.
