X-shaped arm for vehicle air suspension and air suspension assembly based on X-shaped arm

Abstract

The invention relates to an X-shaped arm for a vehicle air suspension, and further relates to an air suspension assembly adopting the X-shaped arm. The X-shaped arm is characterized by comprising a body; the body is integrally formed with a pair of axle connecting arms and a pair of cross beam connecting arms, wherein the axle connecting arms are extended outwards from the body and are symmetrically arranged, the cross beam connecting arms are extended outwards from the body and are symmetrically arranged, and the two axle connecting arms and the two cross beam connecting arms are oppositely arranged relative to the symmetry axes to form an X or H shape; and the cross sections of the cross beam connecting arms and the cross sections of the axle connecting arms are gradually reduced in theextending direction from the body to the outside. The X-shaped arm has the advantages that the stress effect is good, the structure is stable, the structural strength and the stability of the X-shapedarm can be greatly improved after the axle connecting arms and the cross beam connecting arms are subjected to optimized design in molded lines and cross sections, and weight reduction optimization can be carried out on the premise that the structural strength and the stability are greatly improved.

Description

technical field [0001] The invention relates to an X-shaped arm for vehicle air suspension, and also relates to an air suspension assembly based on the X-shaped arm. Background technique [0002] In the context of energy saving and environmental protection, lightweighting of automobile chassis and energy saving and emission reduction are the main development directions of various manufacturers. As an important part of the chassis system of heavy-duty trucks, thrust rods also need to be lightweight. [0003] At present, the rear suspension systems of mainstream heavy trucks mainly include air suspension systems and balanced suspension systems, both of which are matched with thrust rods, and the upper thrust rods generally use V-shaped thrust rods or I-shaped straight thrust rods. [0004] The air suspension system has gradually become one of the mainstream configurations of heavy-duty truck chassis due to its light weight and good comfort. The upper thrust rod of this air sus...

AI Technical Summary

Problems solved by technology

The I-shaped straight thrust rod can only transmit the longitudinal force such as the driving force and braking force between the frame and the axle, but cannot bear the lateral force and has no anti-rolling ability. It must be equipped with a lateral stabilizer bar, but its anti-rolling ability still poor
