TRANSMISSION
Interaxle differential:
If an axle of the vehicle is showing slip, a rigid connection between the vehicle axles can be
created by the differential lock.
In this condition, a torque output of 1 : 1 is realized.
The differential, installed in the output, has the task to transmit different torques on the vehicle axles and to
function as intermediate compensation in the driving direction (longitudinal direction of the vehicle).
Due to the existing differential lock, both functions can be put out of service and a rigid con-nection
between the axles can be created.
Function:
The planetary drive (differential) is designed in such a way that the external internal gear will
be driven.
The output is realized via the planet carrier (4) – great lever arm – and via the internal sun
gear (6) – small lever arm.
Due to these different lever arms (diameters), a torque splitting of 1 : 2 is given in the actual
case as follows:
− Front axle 1/3
− Rear axle 2/3
Due to the special arrangement of the planetary gears (2 and 3) - Ravignaux-System – the required
inversion takes place within the planetary drive, so that both outputs (planet carrier and
sun gear) are running in the same direction of rotation.
VA = Output Front axle
HA = Output Rear axle
