suspension arm

Abstract

The invention relates to a suspension swing arm, which comprises a first arm part, wherein one end of the first arm part is connected with a base plate component, and the other end of the first arm part is provided with a first axle shaft sleeve; the first arm part comprises an upper wing plate, a lower wing plate and a web plate which is connected between the upper wing plate and the lower wing plate; and a cavity is formed on a downward sunken part of the upper wing plate for accommodating a damper. The suspension swing arm is provided with the first arm part which has a goblet-shaped section with a U-shaped top and an I-shaped bottom, so that the suspension swing arm is uniformly stressed, has low probability of bending and twisting deformation, and is simple in a casting process and convenient in processing, and the problem of high probability of bending and twisting deformation under the action of external force in a vehicle running process existing in the suspension swing arm of the prior art is solved; in addition, since the cavity is formed on the downward sunken part of the upper wing plate of the suspension swing arm for accommodating the damper, space for accommodating the damper is provided; and thus, an entire suspension component has a compact structure, and the problem of high probability of damage caused to the damper arranged outside the suspension swing arm existing in the prior art is effectively solved.

Description

technical field [0001] The present invention relates to a vehicle suspension system, in particular to a suspension assembly of the vehicle suspension system, and more particularly to a suspension swing arm of the vehicle suspension system. Background technique [0002] Comfort is one of the most important performances of a vehicle. Comfort is related to the inherent vibration characteristics of the vehicle body, which in turn is related to the characteristics of the suspension system. Therefore, the vehicle suspension system is an important component to ensure vehicle comfort. At the same time, the vehicle suspension system, as a force transmission device connected between the frame (or body) and the axle (or wheel), is also an important part to ensure the safety of the car. [0003] Each suspension system of existing vehicles includes a pair of laterally spaced suspension assemblies, each suspension assembly including a suspension swing arm and chassis components and air s...
