  • Patent number: 11773941
    Abstract: A hydraulic vibration damper may include inner and outer tubes filled with damping liquid, a piston rod projecting axially out of the inner tube and movable in rebound and compression directions, a sealing and guide pack that sealingly closes an end of the outer tube and guides piston rod movement, a working piston for producing damping forces that is fastened to the piston rod and is guided on an inner lateral surface of the inner tube and subdivides the interior of the inner tube into a piston rod-side and piston rod-remote working spaces. The vibration damper has rebound and compression stops. In the piston rod-remote working space, a compression stop, starting from a predetermined retraction travel of the piston rod, may produce a travel- and speed-dependent compression stop force.

  • Patent number: 11511584
    Abstract: A decoupling bearing for a suspension strut or a pneumatic suspension strut may include a suspension strut cup and a connecting element that can be connected to a vehicle body. A damping element may be arranged between the suspension strut cup and the connecting element. The suspension strut cup may be connected to the connecting element by the damping element. Further, the damping element may be adhesively bonded to the connecting element and the suspension strut cup in a force-transmitting manner, and/or the damping element may be adhesively bonded to the connecting element and an intermediate element in a force-transmitting manner. The intermediate element may be connected to the suspension strut cup.
