Chapter 5 Front Suspension System

Description on front suspension structure
This model uses strut swing arm independent suspension with stabilizer bar.
The shock absorber upper end is flexibly connected to the body through the shock absorber mounting seat,
the lower end is rigidly connected to the steering knuckle. The coil spring encloses the shock absorber (coil
spring geometrical axial line does not coincide with that of the shock absorber piston rod), and is supported
between the upper and lower spring seats.
Both ends of the stabilizer bar are connected to the shock absorber through the strut bar ball pin and the
intermediate part is supported on the lower front body by the rubber bushing and support frame.
The front cushion sleeves the shock absorber piston rod head to restrict the wheel jump limit position and
plays the role of buffer.
The thrust ball bearing, installed between the spring upper seat and the shock absorber mount, is used for the
relative rotation upon steering of the shock absorber rigidly connected to the steering knuckle to the shock
absorber mount flexibly connected to the body.
"L" type lower swing arm is secured to the lower engine compartment with the press plate through elastic
rubber bushing and hinge, and its outer end is connected to the steering knuckle through the ball stud pin
which is attached to the lower swing arm by 3 high intension bolts. The ball stud pin can be removed and
replaced when it is worn.
The ball seat material is saturated polyester containing oil, featured in comparatively high intensity and
wearability and good self-lubrication performance. Proper amount of grease has been added during the
assembly and there is no need for additional filling during the normal operation.
