Abstract
Vibration damper with amplitude-dependent damping force includes a cylinder, in which a piston rod, carrying a piston, is guided with freedom of axial movement, where the piston divides the cylinder into a working space on the piston rod side and a working space on the side away from the piston rod. The piston rod carries at least part of a housing, which is mounted in the direction of the piston rod-side working space, and where a separating body is supported inside the housing with freedom to slide. The separating body divides the housing into first and second working chambers, where the first working chamber is connected by at least one radial connecting opening to the piston rod-side working space and the second working chamber is connected by a connecting channel to the working space on the side away from the piston rod. At least a part of the housing is connected to the piston rod by a weld.
