Problems solved by technology

[0009] 1. At present, the selection of front wheel alignment parameters mainly obtains data through experience, semi-empirical, statistics and experiments, and relies on a large amount of experimental work, which consumes manpower and material resources, and the product design cycle is long
[0010] 2. EPS technology is limited by the torque provided by the motor, so it can only be applied to small-tonnage vehicles at present

Abstract

The invention relates to a steering column assembly and a vehicle. The steering column assembly comprises a transmission shaft, a first housing, and an aligning mechanism. The first housing locks on the periphery and surrounds on an upper transmission shaft in an axial moveable manner. The aligning mechanism is connected between the transmission shaft and the first housing, and an elastic piece isarranged between the first housing and the aligning mechanism. The first housing is connected with the transmission shaft in a transmission manner, so that when the transmission shaft rotates relative to the circumferential direction of the first housing, the first housing can move axially relative to the transmission shaft. The aligning mechanism can store energy just in an initial stage when the transmission shaft starts to rotate forward, and subsequent free rotation is not influenced. In alignment, through release of elastic potential energy of the elastic piece which rotates in an opposite direction with the transmission shaft and is on a tail section, a steering wheel is assisted to align, so as to improve returnability performance of vehicle steering, and normal rotation of the transmission shaft is not influenced.

Description

technical field [0001] The present disclosure relates to the field of steering column, in particular, to a steering column assembly and a vehicle using the steering column assembly. Background technique [0002] In the field of automobile technology, the steering wheel return performance of a mechanically steered automobile is more important. The alignment of the current steering can be optimized by: [0003] (1) Improving the steering return performance can optimize the layout of the vehicle, try to use front-wheel drive, and increase the layout of the front axle load as much as possible. [0004] (2) To improve low-speed steering performance, you can choose steel radial tires, choose tires with small aspect ratios, and increase tire pressure appropriately. [0005] (3) To improve the low-speed steering back-to-alignment performance, the caster angle and inclination angle of the kingpin can be appropriately increased without affecting other performances of the vehicle. ...
