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.
