Problems solved by technology

[0004] However, due to the non-adjustability of the caster angle of the front suspension kingpin of the general car during driving, the only driving characteristics of the car are determined, either the low-speed steering is flexible, the high-speed driving is ethereal, or the low-speed steering is heavy, and the high-speed driving is stable, or both. All take the mean, can't have both

Abstract

A vehicle front suspension device comprises a subframe assembly, a lower swing arm connected with the subframe assembly, and a damper assembly connected with the lower swing arm. The vehicle front suspension device also comprises a kingpin caster angle adjusting mechanism which is connected with one end of the damper assembly, the other end of the damper assembly is hinged to the lower swing arm, and the kingpin caster angle adjusting mechanism can drive the damper assembly to swing relative to the lower swing arm according to the change of the vehicle speed. The vehicle front suspension device can automatically adjust the kingpin caster angle to achieve the aim of low-speed steering flexibility and high-speed driving stability of a vehicle and further achieve a good effect of good matching of the driving properties and the speed of the vehicle.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a front suspension device for a vehicle. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, more and more cars are used in people's daily life. In the continuous development of the automobile industry, people pay more and more attention to the stability, safety and comfort of the car in addition to the quality and function of the car. [0003] Generally, the four-wheel alignment of a car is a set of key parameters that determine its driving characteristics, and the caster angle of the front suspension kingpin is one of the key parameters in this set of key parameters that is related to the stability of the car when driving in a straight line and the automatic return of the front wheels after turning. a key item. The larger the caster angle, the better the directional stability, but the heavier the stee...
