1. GENERAL

1.1 DESCRIPTION OF 09N075/09N220 TRAILING AXLE

Vehicles with a trailing axle are typically equipped

with a driven axle followed by a non-driven axle,

i.e. the trailing axle. If the axle load is so low that

this load can be carried by the driven axle only,

the trailing axle can be lifted.

The advantage of this is that tyres, brakes and

fuel are saved.

09N075 trailing axle
The 09N075 trailing axle is an air-suspended rigid

axle with a pneumatic lifting gear.

09N220 trailing axle
The 09N220 trailing axle can be either air-

suspended or leaf-sprung.

The air-suspended trailing axle is a rigid axle with

a pneumatic lifting gear.

With a leaf-sprung trailing axle, the driven rear

axle is suspended by spring assemblies which

are connected (hinged) at the front. On the other

side the spring assemblies are connected to the

trailing-axle wheel yoke using shackles. The lever

effect of the wheel yoke makes sure that the

trailing axle is also suspended. The trailing axle

may or may not be equipped with a hydraulic

lifting gear.

Wheel hub
The wheel hub, wheel bearings and hub oil seal

form a unit, also called the wheel hub unit (3). The

wheel bearings are a compact version.

The thrust washer (2) installed between the hub

nut (1) and wheel bearing, is fitted with two

straight surfaces on the inside to prevent the

washer from turning. This is to prevent the hub

nut (1) from loosening in case of wheel bearing

problems. The hub nut (1) is of the self-locking

type. The nut is locked by bending the lips on the

hub nut outward.

The wheel bearings of the wheel hub unit are

greased and are maintenance free.

The correct wheel bearing pre-load is achieved

by installing the hub nut as specified.
