Abstract
A device for fixing a hub on a shaft, especially for fixing a steering wheel hub on a steering column, using a fastening screw. The screw extends crosswise to the shaft, is guided in the hub and has a cone-shaped section for engaging in a channel or groove is the shaft. When the hub is laid axially on a stop of the shaft, the axis of the screw is situated higher up than the center of the channel or groove of the shaft while the hub rests on the shaft above and below the channel or groove, with a positive fit.

A device for fastening a steering wheel hub on a steering column, comprising:
- a steering column with a stop and a channel with a center;
- a steering wheel hub that bears axially against the stop of the steering column;
- and
- a fastening screw having an axis which runs transversely to the steering column guided in the steering wheel hub, the fastening screw having a conical section for engagement in the channel of the steering column, the conical section having an angle of taper of less than 12 degrees;
- wherein the hub bears in a positive-locking manner against the steering column and below the channel;
- wherein when the hub bears axially against the stop of the steering column, the axis of the screw is situated higher than the center of the channel of the steering column, and
- further comprising toothing between the steering column and the hub above and below the channel.
A steering wheel assembly, comprising:
- a steering column with a stop and a channel with a center;
- a steering wheel hub that bears axially against the stop of the steering column;
- and
- a fastening screw having an axis which runs transversely to the steering column guided in the steering wheel hub, the fastening screw having a conical section for engagement in the channel of the steering column, the conical section having an angle of taper of less than 12 degrees;
- wherein the hub bears in a positive-locking manner against the steering column above and below the channel;
- wherein when the hub bears axially against the stop of the steering column, the axis of the screw is situated higher than the center of the channel of the steering column.
The device for fastening a steering wheel hub on a steering column, comprising:
- a steering column with a stop and a channel with a center;
- a steering wheel hub that bears axially against the stop of the steering column;
- and
- a fastening screw having an axis which runs transversely to the steering column guided in the steering wheel hub, the fastening screw having a conical section for engagement in the channel of the steering column, the conical section having an angle of taper of less than 12 degrees;
- wherein the hub bears in a positive-locking manner against the steering column and below the channel;
- wherein when the hub bears axially against the stop of the steering column, the axis of the screw is situated higher than the center of the channel of the steering column, and
- wherein the channel is formed in the external periphery of the steering column and the fastening screw extends tangentially with respect to the steering column.
