3.1 General description
The drive axle mainly consists of the housing, the wheel hub, the half shaft and the
brake unit. (See Fig3.1) The housing is an integral casting body. The tyre with the rim is
fixed to the hub with studs and nuts. The power is transmitted to the half shaft through the
differential and drives the front wheels through the hubs. Each hub is fixed on the axle
housing with two tapered roller bearings, so that the half shafts bear only torque
transmitted to the hubs. There are oil seals to prevent water and dust from entering and
oil leakage inside the hub.
3.2 Assembly of wheel hub
(1) Fill the chamber of wheel hub with lithium base grease about 100 cc, then fit the
hub on the shaft. (Fig3.2)
(2) Screw down the adjusting nut with a torque for about 1kg.m and then loosen it for
1/2 turn.
(3) Put the spring balance up on the bolt to measure the hubs’ starting torque. When
the starting torque arrives to the specified value, lock the nuts slowly.
Starting torque
:
5 to 15 kg.m (Fig3.3)
(4) Install the lock plates and lock nuts, after that pull the lock plates up to lock the
bolts.
