Problems solved by technology

[0002] The transmission ratio of the steering system in the related art is a certain value, which poses a challenge to the car designers: if the steering transmission ratio is selected to be small, the steering of the vehicle will be more direct at low speeds, but the subtle movements of the steering wheel will be lost when driving at high speeds. It will appear too sensitive, which will affect driving stability and safety; on the contrary, if the steering transmission ratio is selected larger, the steering of the vehicle will appear stable and safe at high speeds, but at low speeds, it will cause the driver to be in a hurry when steering the vehicle

Abstract

The invention provides a steering gear with a variable transmission ratio for a vehicle, and a vehicle having the steering gear. The steering gear with a variable transmission ratio comprises a steering gear body, an output shaft, an input shaft, an upper intermediate shaft and a lower intermediate shaft, wherein the output shaft is connected with the steering gear body; the input shaft is connected with a steering wheel of the vehicle; the upper intermediate shaft is connected with the input shaft; the lower intermediate shaft is connected with the output shaft in a transmission manner; an upper eccentric structure is arranged on the upper intermediate shaft; a lower eccentric structure is arranged on the lower intermediate shaft; and the upper eccentric structure is linked with the lower eccentric structure. According to the steering gear with a variable transmission ratio for a vehicle disclosed by the invention, the upper eccentric structure is arranged on the upper intermediate shaft, and the lower eccentric structure is arranged on the lower intermediate shaft, so that the transmission ratio of the steering gear is variable, and further the steering requirements of the vehicle at a high speed and a low speed are met at the same time.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a variable transmission ratio steering system for vehicles and a vehicle with the same. Background technique [0002] The transmission ratio of the steering system in the related art is a certain value, which poses a challenge to car designers: if the steering transmission ratio is selected to be small, the vehicle will turn more directly at low speeds, but at high speeds, subtle movements of the steering wheel will It will be too sensitive, which will affect the driving stability and safety; on the contrary, if the steering transmission ratio is selected larger, the steering of the vehicle will appear stable and safe at high speeds, but at low speeds, it will cause the driver to be in a hurry when steering the vehicle. Therefore, the traditional steering system must make a trade-off between safety and comfort. Contents of the invention [0003] In order to achieve the above ...
