Rear independent suspension assembly

Abstract

The invention discloses a rear independent suspension assembly. The rear independent suspension assembly comprises a sub-frame assembly, a lower control arm assembly, a spiral spring, a hub bracket assembly, an upper control arm assembly, a rear shock absorber assembly, a cross arm assembly, a rear stabilizer bar assembly and a rear stabilizer bar connecting bar assembly, wherein both ends of thelower part of the lower control arm assembly are fixed to the hub bracket assembly, both ends of the upper part of the lower control arm assembly are fixed to the sub-frame assembly, the spiral springis fixed to the lower control arm assembly, the hub bracket assembly is respectively connected to the lower control arm assembly and the upper control arm assembly, the upper control arm assembly isconnected to the sub-frame assembly, the rear shock absorber assembly is connected to the hub bracket assembly, the cross arm assembly is connected to the sub-frame assembly and the hub bracket assembly, and the rear stabilizer bar connecting bar assembly is connected to the rear stabilizer bar assembly and the lower control arm assembly. The rear independent suspension assembly can improve the handling stability performance and the smooth performance, and at the same time, has the advantages of compact structure, strong bearing capacity, stable and reliable performance and the like.

Description

Technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a rear independent suspension assembly. Background technique [0002] Rear multi-link independent suspension refers to a suspension structure that is composed of three or more connecting rods and can provide control forces in multiple directions, so that the tires have a more reliable driving track. [0003] However, nowadays, because the three-link structure can no longer meet people's higher pursuit of chassis control performance, only four-link and five-link suspensions with more precise structure and more accurate positioning can be regarded as truly multi-link suspensions. Link type, these two suspension structures are usually applied to the front and rear wheels respectively. [0004] Five link type suspensions refer to the main control arm, front positioning arm, rear positioning arm, upper arm and lower arm respectively. Among them, the main control arm can adjust the ...

Problems solved by technology

figure 1 The shown independent suspension has the following advantages: limited unsprung mass, mutual independence of the wheels on both sides for relatively large load changes, relatively large kinematic and elastokinematic design freedom, vibration and noise of the road surface Can be easily isolated; at the same time, the independent suspension also has the following disadvantages: poor off-road performance, only relying on the anti-stabilizer bar to achieve load balance when driving in curves, and less rigid than the integral axle
