Abstract: Suspension strut unit comprising a connector bearing for piston rod of the suspension strut unit, a spring plate for a vehicle spring, and a first has a bearing with a bearing input part on the spring plate side and a bearing output part on the connector bearing side, which bearing allows relative rotational movement between the vehicle spring and the connector bearing of the piston rod. After the piston rod has traveled inward a certain distance, the cylinder is supported against the connector bearing by way of a stop buffer. A second bearing allows relative rotational movement between the connector bearing and the cylinder when the stop buffer is active; the second bearing is located functionally between the stop buffer and the connector bearing, and a functional separation is present between the bearing input part for the spring plate and the second bearing.

Abstract: A retaining cap includes a sleeve-shaped basic body which has at least one protective bellows retaining segment on which a protective bellows can be supported. A component which is movable with respect to the retaining cap can penetrate into the installation space of the retaining cap, the retaining cap having a plurality of deformation regions which are arranged in the circumferential direction. When in contact with the movable component, these regions make possible a free passage for the movable component.

Abstract: Suspension strut unit comprising a connector bearing for a piston rod of the suspension strut unit, where a spring plate for a vehicle spring has a bearing with a connector bearing-side bearing part and a spring plate-side bearing part, which bearing allows relative rotational movement between the vehicle spring and the connector bearing of the piston rod, where, after the piston rod has traveled inward a certain distance, a stop buffer rests against a cylinder; where a second bearing allows relative movement between the connector bearing and the cylinder after the stop buffer has become active; and where the second bearing allows the stop buffer to move relative to the spring plate at an angle to the longitudinal axis of the suspension strut unit.
