Positive Center Feel Torsion Bar





Torsion Bar Components

When the steering wheel motion commences, the spring force of the torsion bar must be overcome.
- The torsion bar is positively connected to the two end pieces.
- The metal bellows spring is arranged co-axially with the torsion bar.
- One end of the metal bellows spring is fastened to one of the end pieces.
- The opposite end is connected to a centering piece.

The prism centering device consists of:
- Two centering pieces each of which has a prism shaped recess at its front end.
- Caged guided balls are arranged between these two recesses.

The zero torsion position of the axially pre-loaded metal bellows spring is determined by the prism centering device.

At the start of the torsional motion, the metal bellows spring produces a substantial additional torsional resistance.

As soon as the prisms of the two centering pieces start being displaced to one another from a torsion bar angle of approximately 0.2 degrees, the torsional rigidity will decrease and become comparable to a conventional torsion bar.
