Rear stabilizer rod components The rear axle of the suspension is a trailing axle, functioning as:
(1) Bearing all force and torque, such as weight, payload, traction, brake force, inertia force, centrifugal force, lateral force and fatigue stress under alternating impact, etc. (2) Reducing vibration and impact, and improving the vehicle comfort and driving stability. The rear axle assembly of LF620 sedan is shown in Fig. 2-2. The rear axle assembly is composed of rear axle welding component 13, left rear shock damper 1, right rear shock damper 6, rear stabilizer bar component 14 and the left and right bushes of rear axle. The rear suspension is a trailing arm suspension with a torsion bar.
The main axis of the body is directly connected with the body and then with the suspension system; then the component is installed on the body. And the spring and shock damper are installed near the vehicle axis. The supporting arm moves around the axis of the center line of the vehicle body, namely parallel to the vehicle axle which moves up and down, parallel to the vehicle body and no camber angle. The 105
