DESCRIPTION AND OPERATION
Differential assembly
Item Description
I 1 1 Bearing I
1 2 1 Crown wheel I
1 3 1 Differential assembly I
4 Sender wheel - Vehicle Speed Sensor
I I (VSS)
The differential assembly is built into the
transmission housing.
The drive torque is transmitted to the differential
by the crown wheel which is bolted to it. The differential
assembly contains differential
pinion gears mounted on a spindle and the axle
halfshaft pinion gears which connect to the front
wheel axle halfshafts through helical gearing.
The axle halfshaft pinion gears can revolve around
the differential pinion gears when the road wheel
speeds are different
(e.g when cornering).
On vehicles without Anti-lock Brake System (ABS)
a VSS detects the speed of the differential
assembly at the VSS sender wheel.
On vehicles with ABS the VSS sender wheel is
also installed. The VSS is however not installed in
this case. A plug with an O-ring closes the
corresponding bore instead.
