3.Transmission, Reduction Gear and Differential
3.1General Description
The drive unit of clutch type truck is a one-body construction consisting of the
transmission, reduction gear and differential (Fig.3-1). The transmission is provided
with a synchromesh mechanism that synchronizes the rotation of gears which are
about to be meshed, ensuring smooth gear shifting. The transmission of this type
avoids clashing gears and reduces noise arising when shifting, especially shifting from
forward to reverse or vice versa.
3.2 Transmission
The transmission consists mainly of a driving shaft, an output shaft, a main shaft
and an idler shaft, each having gear(s) of different sizes on it. The gear(s) can be
shifted with the aid of the synchromesh mechanism installed on the main shaft by
operation of the shift handle. The power from the output shaft is transmitted through
the reduction gear differential and half shafts to the drive shaft.
