Mcpherson suspension connecting structure

Abstract

The invention relates to a Mcpherson suspension connecting structure which comprises a damper, an upper transverse arm, a steering knuckle, a lower control arm lever and a damper mounting bracket, wherein the lower control arm lever further comprises a front control arm lever and a rear control arm lever, the lower end of the steering knuckle is in mounting connection with the front control arm lever and the rear control arm lever by a ball pin connecting way, and a connecting ball pin can slide at the connected parts of the steering knuckle as well as the front control arm lever and the front control arm lever. Based on the traditional Mcpherson suspension structure form, the Mcpherson suspension connecting structure realizes the kingpin inclination angle to be adjustable by changing the connection mode between the steering knuckle and the lower control arm lever, ensures that a suspension platform has stronger adaptability, is convenient for the chassis adjustment at the later stage, has the positioning precision under the control of assembly, is more guaranteed than the current unadjustable Mcpherson suspension, and can balance the steering force and the steering according to actual situations.

Description

Technical field [0001] The invention relates to a vehicle Macpherson suspension structure, in particular to a Macpherson suspension connection structure with an adjustable kingpin angle. Background technique [0002] There are many different types of independent suspensions commonly used in automobiles. Most independent suspensions are derived from the earliest single-wishbone independent suspensions, and the basic principles are basically the same. Automobile independent suspensions are mainly divided into three categories according to the form of wheel movement: 1) Wishbone independent suspension with wheels swinging in the transverse plane of the car; 2) Trailing arm independent suspension with wheels swinging in the longitudinal plane of the car; 3 ) Macpherson independent suspension and candle independent suspension with wheels moving along the kingpin. [0003] Among them, the MacPherson suspension usually consists of two basic parts: strut-type shock absorber and A-shaped s...

Problems solved by technology

Therefore, the kingpin inclination through this point cannot be adjusted

The designer reported that when designing different vehicles on the same platform, due to the different tire sizes, the offset distance of the kingpin is very different, and some of them cannot meet the requirements of use. It is necessary to redevelop components such as control arms

In addition, due to the increase of the wheelbase, the offset distance of the wheel will also change, which will also lead to a corresponding change in the offset distance of the kingpin. If the offset distance cannot be adjusted, there will be adverse conditions such as tire wear and excessive steering force.
