The receiving arrangement may include a bearing unit by way of which the damper tube can twist relative to the carrier spring about a longitudinal axis of the suspension strut. The bearing unit may include an upper bearing ring and a lower bearing ring, which bearing rings may be configured so they can slide on each other to form an axial bearing and a radial bearing between the carrier spring and the damper tube. ## Claims ### Claim 1 A receiving arrangement of a lower end of a carrier spring on a damper tube of a shock absorber of a suspension strut, the receiving arrangement comprising a bearing unit by way of which the damper tube twists relative to the carrier spring about a longitudinal axis of the suspension strut, the bearing unit comprising an upper bearing ring and a lower bearing ring that are configured to slide on each other to form an axial bearing and a radial bearing between the carrier spring and the damper tube, wherein the lower bearing ring is configured as a shoulder plain bearing and has an L-shaped cross-sectional profile, wherein a horizontal base leg of the L-shaped cross-sectional profile forms the axial bearing, wherein an upright leg of the L-shaped cross-section profile forms the radial bearing. ### Claim 2 (depends on 1) The receiving arrangement of claim 1 comprising a spring seat on which the lower end of the carrier spring sits, wherein the upper bearing ring is disposed twist-resistantly on the spring seat. ### Claim 3 (depends on 2) The receiving arrangement of claim 2 comprising a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring. ### Claim 4 (depends on 2) The receiving arrangement of claim 2 wherein the spring seat is configured as a soft component with elastic yielding properties that reduce noise. ### Claim 5 (depends on 1) The receiving arrangement of claim 1 wherein the upper bearing ring seals in slip fashion against an outside of the damper tube. ### Claim 6 (depends on 1) The receiving arrangement of claim 1 comprising a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring. ### Claim 7 (depends on 6) The receiving arrangement of claim 6 wherein a labyrinth seal is formed between the upper bearing ring and the supporting ring on an outside for arrangement of the lower bearing ring. ### Claim 8 A suspension strut for a vehicle with a receiving arrangement of a lower end of a carrier spring on a damper tube of the suspension strut, the receiving arrangement comprising a bearing unit by way of which the damper tube twists relative to the carrier spring about a longitudinal axis of the suspension strut, wherein the bearing unit comprises an upper bearing ring and a lower bearing ring that are configured to slide on each other to form an axial bearing and a radial bearing between the carrier spring and the damper tube, wherein the receiving arrangement comprises a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring, wherein the supporting ring has a radial carrier portion that extends to between the upper bearing ring and the damper tube, wherein an upright leg of a cross-sectional profile of the lower bearing ring rests radially inwardly on the radial carrier portion to form the radial bearing. ### Claim 9 (depends on 8) The suspension strut of claim 8 wherein the receiving arrangement comprises a spring seat on which the lower end of the carrier spring sits, wherein the upper bearing ring is disposed twist-resistantly on the spring seat. ### Claim 10 (depends on 9) The suspension strut of claim 9 wherein the receiving arrangement comprises a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring. ### Claim 11 (depends on 9) The suspension strut of claim 9 wherein the spring seat is configured as a soft component with elastic yielding properties that reduce noise. ### Claim 12 (depends on 8) The suspension strut of claim 8 wherein the lower bearing ring is configured as a shoulder plain bearing and has an L-shaped cross-sectional profile, wherein a horizontal base leg of the L-shaped cross-sectional profile forms the axial bearing, wherein an upright leg of the L-shaped cross-section profile forms the radial bearing. ### Claim 13 (depends on 8) The suspension strut of claim 8 wherein the upper bearing ring seals in slip fashion against an outside of the damper tube. ### Claim 14 (depends on 8) The suspension strut of claim 8 wherein a labyrinth seal is formed between the upper bearing ring and the supporting ring on an outside for arrangement of the lower bearing ring. ### Claim 15 A receiving arrangement of a lower end of a carrier spring on a damper tube of a shock absorber of a suspension strut, the receiving arrangement comprising a bearing unit by way of which the damper tube twists relative to the carrier spring about a longitudinal axis of the suspension strut, the bearing unit comprising an upper bearing ring and a lower bearing ring that are configured to slide on each other to form an axial bearing and a radial bearing between the carrier spring and the damper tube, wherein the receiving arrangement comprises a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring, wherein the supporting ring has a radial carrier portion that extends to between the upper bearing ring and the damper tube, wherein an upright leg of a cross-sectional profile of the lower bearing ring rests radially inwardly on the radial carrier portion to form the radial bearing. ### Claim 16 (depends on 15) The receiving arrangement of claim 15 wherein a labyrinth seal is formed between the upper bearing ring and the supporting ring on an outside for arrangement of the lower bearing ring. ### Claim 17 The receiving arrangement of 16 wherein the upper bearing ring seals in slip fashion against an outside of the damper tube. ### Claim 18 (depends on 15) The receiving arrangement of claim 15 comprising a spring seat on which the lower end of the carrier spring sits, wherein the upper bearing ring is disposed twist-resistantly on the spring seat. ### Claim 19 (depends on 18) The receiving arrangement of claim 18 comprising a supporting ring that sits on the damper tube, wherein the lower bearing ring is disposed twist-resistantly on the supporting ring. ### Claim 20 (depends on 18) The receiving arrangement of claim 18 wherein the spring seat is configured as a soft component with elastic yielding properties that reduce noise.
