STRUCTURE AND FUNCTION

FUNCTION The clutch is a device which automatically disengages the drive between the large diplacement (Rear) travel motor and the transmission. This occurs when the machine is accelerating and the disengagement occurs at 11 Kph. The transmission system becomes more efficient (by reducing losses caused by the unnecessary rotation of the rear travel motor) providing better acceleration and enabling a maximum speed of 30 Kph. When the machine decelerates from a high speed the clutch will re-engage automatically at 9 Kph and will remain engaged until the speed is increased above 11 Kpm again.

STRUCTURE AND FUNCTION

AXLE

AXLE OUTLINE • Each axle consists of an axle housing supporting the chassis weight, a differential set in the axle housing, a final drive, and a brake provided at each end.

•

A trunnion-type axle shaft with a king pin at the final drive end is used to enable the direction of travel of the machine to be changed.
