0 a device fitted to the axle of a vehicle that allows the wheels to turn at different rates when going around a corner
As can be remarked, the propagation of external and inertial forces acting on the second link is twofold: through the internal transmission (differential gear) and via the manipulator links.
It is like the differential gear on the back axle of a car: it allows the vehicle to manoeuvre without tearing itself apart on the back axle.
Lacking this extra gear meant that reverse was done with a differential gear.
This design would have been simpler than using a differential gear.
They steered through an unusual wet band brake system through a differential gear system.
The rear differential gear ratio was changed to 3.31:1 for both transmissions.
The explanation was that the differential gear in the rear axle had been fitted incorrectly.
On the ground the engine drove the main wheels through a differential gear, as normal, and the car was steered by its nosewheel.
