The front axle of the 4WD is constructed as shown above. Power is transmitted from the transmission case
through the propeller shaft(17) to the spiral bevel pinion shaft(18), then to the spiral bevel gear(11) and to
the differential side gear(19).
The power through the differential side gear is transmitted to the differential yoke shaft(7), (14), and to the
bevel gear shaft(20) through the bevel gears(4), (6) in the bevel gear case(5).
The revolution is greatly reduced by the bevel gears(21), (3), then the power is transmitted to the axle(1).
The differential system allows each wheel to rotate at a different speed to make turning easier.
