Automobile air spring type double wishbone independent suspension device

Abstract

The invention discloses an automobile air spring type independent suspension device with double cross arms. The suspension device comprises four control arms, two air springs, two vibration absorbers, two steering knuckle arms, two steering knuckles, a gear and rack steering device, two steering and limiting devices, two height control valves, four control arm spherical pins and two steering spherical pins. The four control arms respectively comprise a first upper control arm, a first lower control arm, a second upper control arm and a second lower control arm; the first upper control arm and the first lower control arm are arranged on one side of a frame; and the second upper control arm and the second lower control arm are arranged on the other side of the frame. According to the independent suspension device, the smoothness of vehicle driving and the stability of the operation can be improved; and meanwhile, the damages of a heavy-duty vehicle to a road surface are reduced, the service life of the air springs is prolonged and the space for distributing a suspension is reduced.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an independent suspension device, in particular to an air spring type double-wishbone independent suspension device for automobiles. Background technique [0002] At present, the front suspension used in 7m-8m buses is torsion bar spring-type double wishbone independent suspension. The width of the frame and the wheel base are limited. [0003] In addition, the current common arrangement of air springs is that the piston and the bladder are coaxial, and both are perpendicular to the ground. This arrangement is not conducive to the effectiveness of the air spring and affects the service life of the air spring. At present, no one has adopted an air spring type double wishbone independent suspension in the front suspension form of a 7-8 meter bus. [0004] In view of this, there is an urgent need to design a new double-wishbone independent suspension device for automobiles now, s...
