Definitions
- the present invention relates to a steering column for a steer-by-wire steering system for a motor vehicle.
- the desired steering angle is transmitted from the steering wheel to the two front wheels via a mechanical connection.
- the steering torque is amplified by a servo gear so that easy steering is possible.
- the steering shaft and steering wheel hub are fixed in this invention, meaning they cannot rotate.
- the steering column feedback actuator consists of a primary feedback unit and a secondary feedback unit.
- the secondary feedback unit includes a small motor which acts on the primary feedback unit via a gearbox. Higher moments can be generated by the gearbox.
- FIG. 1 shows the steering column according to the invention in a cross section
- the steering column according to the invention can be seen in a cross section in FIG.
- the steering wheel 1 consists of a steering wheel rim 7 and a steering wheel hub 2, which is fixed.
- the steering wheel hub 2 is attached to the end of the steering shaft 6, which also cannot rotate.
- the steering column feedback actuator consists of a primary feedback unit and a secondary feedback unit.
- the primary feedback unit comprises a motor 3 which is arranged inside the steering wheel 1.
- the motor 3 has an inner part 5 which is fixedly arranged on the steering shaft 6 and therefore cannot rotate either.
- An outer part 4 of the motor 3 can rotate and is connected to the housing 8 of the primary feedback unit.
- the housing 8 of the primary feedback unit also carries the steering wheel rim 7. The motor 3 thus acts directly on the steering wheel 1.
- a gear 15 is fixed on the housing 8 of the primary feedback unit by an interference fit.
- the electric motor 12 carries the gear wheel 14 and thus drives the gear wheel 15 .
- a corresponding form of toothing can be selected, for example a helical toothing, in order to enable low-noise operation.
