DETAILED DESCRIPTION OF THE INVENTION

[0032] FIG. 1a shows a partial view of a chassis 2 according to aspects of the invention for use in a motor vehicle 80 with variably adjustable drive height H according to a first exemplary embodiment.

[0033] As can be seen according to FIG. 1a, the chassis 2 according to aspects of the invention comprises a subframe assembly 4 for fastening wheel suspensions 6 of a motor vehicle 80, a plurality of control arms 8 for guiding a wheel carrier 10, wherein the control arms 8 are fastened to the subframe assembly 4 via control arm attachment points 12. The chassis 2 according to aspects of the invention furthermore comprises a plurality of eccentric adjustment devices 14 for adjusting the toe-in V and the basic camber G of the motor vehicle 80 as well as an insert element 16 (not visible here) for receiving an eccentric adjustment device 14, wherein the insert element 16 is designed and can be arranged within the chassis 2 in such a way that the position of at least one eccentric adjustment device 14 can be varied by varying the arrangement of the insert element 16 within the chassis 2.

[0034] FIG. 1b shows a further partial view of the chassis 2 according to aspects of the invention of FIG. 1a, in which a further eccentric adjustment device 14 is arranged at the U3 control arm attachment point 12′.

[0035] FIG. 2 shows a further partial view of the chassis 2 according to aspects of the invention of FIG. 1a in a first position P1 (left) and a second position P2 (right).

[0036] As can be seen according to FIG. 2, the insert element 16 is in the present case arranged on the subframe assembly 4 in an opening 20 (not visible now) of the subframe assembly 4.

[0037] The insert element 16 is designed here in such a way that when increasing the drive height H in the Z-direction, the position of the eccentric adjustment device 14 arranged within the insert element 16 can be varied by varying the positioning of the insert element 16 on the subframe assembly 4.

[0038] Here, the insert element 16 is designed in the present case in such a way that it can be arranged in two different positions P1, P2 on the subframe assembly 4, wherein the different positions P1, P2 provide two different Z-locations for the at least one eccentric adjustment device 14.

[0039] FIG. 3 shows the profile of the change in toe-in V for a motor vehicle 80 according to aspects of the invention in the first position P1 at a lower drive height H and in the second position P2 at an increased drive height H.

[0040] As can be seen according to FIG. 3, the changes in toe-in in the first position P1 and in the second position P2 show the same profile.

[0041] FIG. 4a shows an insert element 16 according to aspects of the invention for receiving an eccentric adjustment device 14.

[0042] As can be seen according to FIG. 4a, the insert element 16 has an opening 22 for inserting an eccentric adjustment device 14, wherein the opening 22 in the present case is arranged asymmetrically, in particular decentrally, within the surface of the insert element 16.

[0043] The insert element 16 furthermore comprises fastening means 26 for the form-locking fastening to a connecting element 24, wherein the insert element in the present case has four fastening means 26.

[0044] FIG. 4b shows a connecting element 24 according to aspects of the invention for the form-locking and/or friction-locked fastening of the insert element in an inserted state.

[0045] As can be seen according to FIG. 4b, the connecting element 24 is provided in the present case for the form-locking fastening of the insert element 16 to the subframe assembly 4 and has an opening 28.
