Operation:
Front Suspension
The front suspension is a double wishbone independent suspension type. The front suspension is composed of a front subframe assembly, front strut assemblies (including damping and springs), upper control arms, lower control arms, tension struts, front knuckles, stabilizer bar, stabilizer links and other accessories. The upper control arm connects to the chassis (with 2 bushings) and to the front knuckle through a ball joint.
The lower control arm and the tension strut are connected to the subframe on one end via bushing, and to the front knuckle via ball joints.
The strut assembly is supported at the upper installation point by the upper strut mounting assembly installed on the strut tower. The lower end is connected to the lower control arm. The coil spring is installed between the two spring seats of the strut assembly.
The damper is equipped with a dirt cover to prevent dirt or water from entering.
The front subframe assembly is welded by several stamped steel plates. It connects to the car body through bolts.
The front stabilizer bar connects to the subframe through mounting clamps, bushings and four bolts. The end links at both ends connect to the strut assembly. The jolting and rebound movement that affects one wheel is partially transmitted to the other wheel of the vehicle to stabilize the body rotation.
Level Sensor System
Through the connection to the chassis, the sensor detects a difference in level between the front axle and rear axle, by means of which the headlamp levelling is automatically adjusted.
