- a tracking of the propeller shaft 8 in a compression or rebound, or in a vertical movement of the wheel is not necessarily a full height adjustment of the plate 19 and thereby brought about horizontal alignment of the second shaft portion 16 ahead, but can also by pivoting the second shaft portion 16 in
- the plate 19 is displaceable on a linear guide 21 parallel to the longitudinal axis of the vehicle 4.
- the linear guide 21 and thus the plate 19 are mounted vertically adjustable via a lifting device 22.
- the linear guide 21 can be operated controlled by a linear motor 24 and thus the
