Rear axles for two-wheel drive vehicles with dependant
rear suspensions are adopted, mainly composed of final
drive, differential and axle housing, which are the final
stage transmission mechanism in vehicle power train.
The final drive, consisting of driving gear and driven
gear, functions for changing driving direction, reducing
speed and increasing torque. Driving gear is connected
with universal joint assembly of propeller shaft through
driving gear flange at one end of spline, with its middle
part supported by two conical bearings installed
reversely for bearing axial force and tangential force and
the small end face journal of driving gear installed on
cylinder roller bearing for bearing radial force only. The
driven gear is fixed on the differential left housing by
using a set of bolts.
Differential, for realizing different rotation speed of left
and right wheels, is mainly composed of left and right
housings of differential, spider, four planetary gears and
two differential gears.
One end of rear axle shaft is connected with differential
gear with spline and the flange at the other end is
connected with wheel hub assembly with brake drum by
using bolt.
