Abstract
A suspension strut used in a wheel suspension of an automotive vehicle, includes a shock absorber, a suspension strut bearing, and a coil spring at least partially coaxially surrounding the shock absorber and having one spring end supported by the shock absorber. The suspension strut bearing includes two plastic carrier elements, and a roller bearing positioned between the carrier elements. One carrier element is a guide ring connected to a vehicle body of the vehicle, and the other carrier element is a single-piece housing having incorporated therein plural hollow chambers in partial concentric surrounding relationship to the shock absorber and formed with a guide collar and a support surface for supporting the other end of the coil spring. The guide ring has a radially inner collar and a radially outer collar which together receive the roller bearing and extend at least beyond a midsection of the roller bearing.
