Abstract

An impact damper includes two tubes which are slidable one in the other for braking a vehicle impact against an obstacle by hydraulic damping forces and pneumatic spring forces. The inner tube is closed off by a bottom. A gas chamber containing a high pressure gas cushion is arranged adjacent to the bottom and bounded by a separating piston that is guided sealingly and displaceably in the inner tube. A first fluid chamber is arranged between the separating piston and a partition fixed in the inner tube and provided with choke openings. A second fluid chamber is formed by the outer tube and connected to the first fluid chamber via the partition. The outer tube has a tapering region directed away from the partition, and a deformation element dividing the second fluid chamber into two part chambers.
