1.3 Gearbox & axle assembly
The gearbox & axle assembly mainly consists of the housing, differential, half shaft,
wheel hubs, brake and the wheels. It is installed in the front of the frame.
The housing of 1-2.5t truck is a fission cast. The housing of 3-3.5t truck is of wholly
casted structure. The tyre with the rim is fixed to the hub with bolts and nuts. The power
is transmitted to the half-shafts through the differential and drives the front wheels
through the hubs. Each hub is fixed on the housing with two tapered roll bearings, so that
the half-shafts bear only the torque transmitted to the hubs. In the inside of the hub are oil
seals to prevent water and dust from entering or oil leakage. (See Fig. 1-2)
The tyre, rim and the pressure of the front wheel are followed. (See Table 1-1)
