<p>A steering unit (5) for a steer-by-wire steering system is provided, said steering unit (5) comprising a steering shaft (6) having a connecting position (13) for a connection to a steering element, a sensor arrangement (8) connected to said steering shaft (6), and force feedback means (9) acting on the steering shaft (6) and return spring means (26) acting on the steering shaft (6). It is intended to provide an almost realistic feedback behaviour. To this end said steering shaft (6) comprises a first section (11) and a second section (12), said first section (11) comprising said connecting position (13), said return spring means (26) acting on said second section (12), wherein the first section (11) and the second section (12) are coupled by coupling moment means (19), said coupling moment means (19) allowing a rotation of the to sections (11, 12) relative to each other over a limited angle.</p> |
