Abstract

A suspension strut including a piston rod extending from a cylinder, a connection bearing for connecting the piston rod to a vehicle body, a spring loading the cylinder away from the connection bearing, and a spring plate supporting the spring axially with respect to the connection bearing. A first bearing enables relative rotational movement between the spring plate and the connection bearing, and a second bearing enables relative rotational movement between the connection bearing and a stop buffer arranged between the connection bearing and the cylinder.
