Cement mixer engine power through the clutch, transmission, drive shaft, and finally transferred to the drive axle and then assigned to the left and right axle drive wheels, power transmission in this way, is the last drive axle assembly, its main component is a deceleration and differential. Action is decelerating torque-reducer, this feature relies entirely between the gear and the gear is completed, it is easier to understand. The differential is more difficult to understand, what is differential, why should "differential"?

Concrete mixer differential is driven car of the main pieces. Its role is to transfer power to the axle on both sides at the same time, allowing both sides of the axle to rotate at different speeds, as much as possible to satisfy both sides of the wheel does not scroll equidistant with pure form, reducing tire friction with the ground.

Cement mixer when turning the wheel-rail line is an arc, if concrete mixer truck to turn left, the center point of the arc on the left, at the same time, the right side of the wheel to go longer than the left wheel arc, to balance this difference, it is necessary to slow down the left wheels and right wheels a little faster, with a different speed to compensate for the difference in the distances.
