Abstract
Official abstract text for this publication.
A steering system is provided with an uninterruptible mechanical positive coupling between a steering wheel and a pinion in the form of a steering shaft and with an electrical auxiliary power assistance, in which an electric motor introduces its assistance power into the steering system via a reduction gear mechanism. A switchable magnetic brake is provided, which in a closed switching state blocks the motor shaft of the electric motor frictionally in relation to a motor housing fixed to the vehicle body, and which in an open switching state releases the motor shaft so that this can rotate in a fixed transmission ratio with the steering shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A steering system including: an uninterruptible mechanical positive coupling between a steering wheel and a pinion in the form of a steering shaft; an auxiliary shaft, which is coupled in a torque-resistant manner via a reduction gear mechanism to the steering shaft; and a switchable magnetic brake, which in an open switching state is configured to release the auxiliary shaft so that the auxiliary shaft can rotate in a fixed transmission ratio with the s…
