1.1 DESCRIPTION OF 1355T, GENERAL

The 1355T tandem gear is a double-drive tandem

gear with hub reduction. The rear-axle housing is

of a very light but rigid construction. Due to this

construction the banjo-housing cover is not

welded to the axle housing but attached using

bolts. These bolts, which run right through the

axle housing, also attach the differential to the

axle housing.

In the first axle the torque is divided over the first

and second axle. To enable speed differences

between the two axles, a so-called third

differential is installed. If required, the differential

can be locked. Via the axle shafts the torque is

transferred to the wheel hubs, where, using a

second reduction, the torque is used to drive the

wheels.
