Abstract
A receiving arrangement may be utilized by a lower end of a carrier spring on a damper tube of a shock absorber of a suspension strut, in particular for a vehicle. 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.

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.
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.
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.
The receiving arrangement of 16 wherein the upper bearing ring seals in slip fashion against an outside of the damper tube.
