FRONT AXLE

N6-M1

1. STRUCTURE

The front axle of the 4WD is constructed as shown above. Power is transmitted from the transmission through the

propeller shaft (16) and to the bevel pinion shaft (15), then to the bevel gear (18) after that to the differential gear.

The power through the differential is transmitted to the differential yoke shaft (12), and to the bevel gear shaft (8)

in the front axle case (7).

The revolution is greatly reduced by the bevel gears (6), (3), then the power is transmitted to the axle (4).
The differential system allows each wheel to rotate at a different speed to make turning easier.
