Chapter 4 Suspension driving and axles

Section 1 Front suspension

I.

Construction features

Front suspension adopts Macphersan absolute suspension, which consists of stabilizer bar, spiral spring and

telescopic type absorber.

Shape of Macphersan suspension construction: Macphersan suspension is aggregation of spiral spring and

absorber, in which lower terminal of front strut connect with knuckle directly so that the strut rotates along with

knuckle while wheel is rotating. The upper terminal connects with vehicle body directly via rubber vibration

Isolator, which could isolate some noise, and buffer vibration from grounding. As a result, upper terminal of strut

is fixed on vehicle body, which moves slightly along with movement of vehicle body, while lower terminal

jumps upwards and downwards along with rotation of wheel, so that strut is impacted by lateral force during

operation of it. Middle part of strut connects in series with spiral spring and parts of buffer block and bearing that

are used for position limiting. Such kind of construction will save more cost, provide more space for collocation

of engine, as well as offer a simple and compact institution.

II. Disassembly and assembly of front absorber

1.

Disassembling step

1.1

absorber and steering knuckle with 19 #socket

wrench and box wrench.

Moment of force: 70±3N.m

1.3

Take down cover on absorber.

48

1.4

Lay down vehicle and open front cover,

disassemble nuts from upper terminal of absorber

with 22# torque wrench, and then take down

absorber.

Moment of force: 60±10Nm

2.

Assembling step

2.1
