2.2 Reducer and differential (Fig2.2)
The reducer located in the front of the transmission is used to reduce the speed and
increase the torque from the output shaft of the transmission and transfer them to the
differential. It consists primarily of a small spiral bevel gear assembled on the output shaft
and a pinion shaft splinted with a big spiral bevel gear. Both ends of the pinion shaft are
supported by tapered roller bearing. Several shims are installed between the case and
bearing covers to adjust the clearances between them.
The differential is housed in the front portion of the differential the front end of which
is connected with the axle housing. The differential case is bilateral symmetry. The
differential includes two halfshaft gears and four planet gears. The thrust washers are
installed between the differential case and each gear, which make the clearance among
gear pairs is proper. The planet gears are supported by gear shaft
Ⅰ
and
Ⅱ
. The gear
shaft
Ⅰ
and gear ring 1 are fixed to the differential case respectively with column pin and
hinged bolt.
The power from the transmission is transmitted through the reduction gear,
differential, halfshaft gear and halfshaft to driving wheels.
