Conventional rear axles have a V section which
is open facing forward. In this configuration, the
shear centre of the axle is located behind the V
section.
The centre of rotation is an imaginary axis about
which the axle rotates when the suspension
experiences a bump on one side.
If the shear centre is behind the V section, then
diagonally aligned track-correcting mountings
have to be used to achieve a self-steering effect.
The new torsion beam rear axle has a V
section which is open downwards. The shear
centre is located above the V section.
The axle has different rotational characteristics
as a result.

Running Gear
When cornering, the inside and outside cornering
wheels go through rebound and bump respec-
tively, because the car body tilts to the outside.
The axle is twisted in itself. The bumped wheel
adopts the toe-in position, while the rebound
wheel adopts the toe-out position.
