Abstract

A relative guide device ( 1 ) for a steering arrangement ( 31 ) is arranged on the wheel-carrier side for the spatial guidance and maintenance of the relative spatial orientation of the steering arrangement ( 31 ) with respect to a vehicle body ( 40 ). At least one telescopic movement apparatus ( 2 ) for movably connecting the steering arrangement ( 31 ) is arranged on the wheel-carrier side to the vehicle body ( 40 ). A steering force transmission device ( 30 ) transmits a steering force to a wheel (R) of a vehicle having a relative guide device ( 1 ), and to a wheel suspension ( 50 ) for a vehicle.

First claim

The invention claimed is:

1. A relative guide device for a steering arrangement arranged on a wheel-carrier side and for spatial guidance and maintenance of a relative spatial orientation of the steering arrangement with respect to a vehicle body, the relative guide device comprising:
a guide apparatus configured to move a first connecting element relative to the vehicle body, wherein the guide apparatus is a parallelogram guide; and
a telescopic movement apparatus configured to movably connect the steering arrangement arranged on the wheel-carrier side to the first connecting element.

2. The relative guide device according to claim 1 , wherein the telescopic movement apparatus comprises at least one extendable element and at least one slide bearing apparatus, wherein the at least one extendable element is guided in the at least one slide bearing apparatus so as to be linearly movable.

3. The relative guide device according to claim 1 ,
wherein the guide apparatus comprises two guide elements,
wherein each of the two guide elements is connectable to the vehicle body by a first joint and connected to the first connecting element by a second joint, and
wherein one of the first and second joints is a ball joint and another of the first and second joints is a swivel joint.

4. The relative guide device according to claim 1 ,
wherein the guide apparatus comprises two guide elements, the first connecting element, and a second connecting element,
wherein a ball joint is arranged at a first end of each of the guide elements and a swivel joint is arranged at a second end of each of the guide elements, and
wherein the connecting elements connect the two guide elements to one another at the second end thereof in such a way that the connecting elements are rotatable relative to the guide elements by means of the swivel joints.

5. A steering force transmission device for transmitting a steering force to a wheel of a vehicle, the steering force transmission device comprising:
a steering arrangement which is arranged on a wheel-carrier side and which moves with a steering axis of a vehicle wheel relative to a vehicle body,
a steering force transmission shaft for transmitting the steering force from a steering force apparatus arranged on the vehicle body to the steering arrangement, and
a relative guide device according to claim 1 ,
wherein the steering force transmission shaft is designed to be telescopic in order to continuously ensure a transmission of the steering force when a position of the steering axis and thus the steering arrangement changes relative to the vehicle body,
wherein the steering force transmission shaft is designed as a Cardan shaft,
wherein two Cardan joints of the Cardan shaft have a same bending angle, and
wherein a housing part of the steering arrangement is connected to the relative guide device by a cylinder joint.

6. The steering force transmission device of claim 5 :
wherein the steering force transmission shaft comprises two joint forks, one of which is arranged on the steering arrangement and the other on the steering force apparatus, and
wherein the joint forks are positioned in a plane.

7. The steering force transmission device of claim 5 :
wherein the steering arrangement is a steering gear, and
wherein the steering gear is a bevel gear.

8. The steering force transmission device of claim 7 , further comprising a sensor for detecting a wheel rotation arranged on a bevel gear wheel, an axis of rotation of which forms an axis of rotation of the vehicle wheel.
