Independent front suspension system of adjiustable front wheel positioning parameter

Abstract

The present invention belongs to the field of mechanical engineering technology. The independent front suspension system with adjustable front wheel positioning parameters includes six rod end bearings, lining sleeves, locking nuts, upper cantilever, the lower cantilever, steering knuckles, and connecting screws and nuts. The locking nuts are set on the screw rods of the rod end bearings; the six rod end bearings and the locking nuts are set separately inside the screw holes of ends of the upper cantilever and the lower cantilever; each of the rod end bearings of the upper cantilever and the lower cantilever in the vehicle body side is connected to the screw and nut of the fixed suspension; and the rod end bearings of the upper cantilever and the lower cantilever in the steering knuckle side have lining sleeves set on two sides of the ball rollers and are connected to the steering knuckles. The present invention can trim the front wheel positioning parameters in relatively great ranges.

Description

technical field [0001] The invention relates to equipment in the technical field of mechanical engineering, in particular to an independent front suspension system with adjustable front wheel alignment parameters. Background technique [0002] The traditional independent front suspension for vehicle is composed of upper cantilever, lower cantilever and steering knuckle. The upper cantilever and the lower cantilever are connected with the vehicle body through bolts, and the steering knuckle is connected with the upper and lower cantilever through a pair of fixed ball joints. This type of suspension structure is simple and strong, and is suitable for vehicles that have been finalized and mass-produced. The disadvantage is that the adjustment range of the geometric parameters of this suspension is quite limited or cannot be changed, so the adjustment of the steering wheel positioning parameters, including the kingpin caster angle, the kingpin inclination angle, and the left an...

Problems solved by technology

The disadvantage is that the adjustment range of the geometric parameters of this suspension is quite limited or cannot be changed, so the adjustment of the steering wheel positioning parameters, including the kingpin caster angle, kingpin inclination angle, and left and right wheelbase, has considerable limitations.

This kind of suspension generally cannot be adjusted in a large range to make up for errors caused by processing and assembly. At the same time, according to specific driving conditions and situations, the ability to change the driving characteristics of the vehicle by adjusting these positioning parameters is also extremely limited.

[0003] After searching the prior art documents, it was found that Wang Liliang, Zhang Dianlong and Song Chuanping wrote in "Modern Automobile Wheel Alignment Parameter Adjustment Method" (magazine name: Automobile Repair and Maintenance, p23-25 ​​(2003.12 issue); p22-25 (2004.2 issue)) In it, it is mentioned that the suspension system structures of different models are different, and the suspension and steering systems are very different, so the positioning parameters and adjustment methods that can be adjusted are also different, which brings difficulties to the maintenance and adjustment of automobiles. great difficulty

At the same time, the adjustment function of all positioning parameters provided by these suspension systems is often limited, and it is impossible to fine-tune each front wheel positioning parameter
