Problems solved by technology

In order to ensure ride comfort, ordinary double-wishbone suspension not only reduces the longitudinal stiffness of the suspension, but also reduces the stiffness of the caster drag moment, which will have an adverse effect on the straight-line braking stability and cornering braking safety.
like Image 6 As shown, the ordinary double wishbone suspension is equivalent to the lack of linkage components 4

Abstract

The invention relates to the technical field of automobile suspensions, and discloses a double-fork-arm suspension which comprises a steering knuckle, a first fork arm, a second fork arm and a linkage assembly. The first fork arm comprises a first fork arm body and a first connecting part arranged on the first fork arm body, and one end of the first fork arm body is connected with the upper end of the steering knuckle; the second fork arm comprises a second fork arm body and a second connecting part arranged on the second fork arm body, the second connecting part corresponds to the first connecting part, and one end of the second fork arm body is connected with the lower end of the steering knuckle; one end of the linkage assembly is connected with the first connecting part, and the other end of the linkage assembly is connected with the second connecting part. According to the invention, the rigidity of the suspension in the X-axis direction is reduced without reducing or even improving the backward tilting towing torque rigidity, so that the performance of the whole vehicle is improved, and the linear braking stability and the curve braking safety are ensured.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to a double wishbone suspension. Background technique [0002] In the automotive field, in order to improve the ride comfort of the whole vehicle, the suspension is generally provided with a small stiffness in the driving direction. When the wheel is impacted by the road surface, reducing the stiffness can significantly reduce the impact strength. In order to achieve the purpose of reducing the stiffness of the suspension in the traveling direction, the upper and lower wishbone rear bushings in the double wishbone suspension are set to a smaller stiffness, which reduces the stiffness, and also reduces the rear inclination angle and rear inclination. Drag moment stiffness, resulting in a significant reduction in caster angle and caster drag moment under braking. The caster angle is the angle at which the steering axis is inclined to the rear side of the vehicle relativ...
