Abstract

The invention relates to a spring-and-damper unit with an external storage device for installation between a vehicle body and a wheel guidance part. To create the greatest possible supporting length for the piston rod in a given installation space, the storage device is preferably connected to a spring plate, on which rests a carrying spring embodied as a coil spring, while the spring plate is arranged in a pressure-tight fashion on the cylinder or a container surrounding the cylinder. The interior of the cylinder or the container is hydraulically connected to the storage device via a connecting channel in the spring plate.
