  • Patent number: 8109491
    Abstract: A vibration damper, comprising a damping medium-filled cylinder, in which a piston rod is guided with freedom of axial movement, where, inside a working space in the cylinder, a stop spring in the form of a circular ring is located, which, after the piston rod has reached a defined stroke position, is compressed between a stop surface on the piston rod side and an end surface forming an axial boundary of the working space, and where the stop spring also forms a boundary of a radially inner space, which is connected to the working space outside the stop spring by means of at least one radial channel. The stop surface on the piston rod side and/or the axially limiting end surface is formed by a rigid body and is provided with at least one radial channel, which extends from the radially inner space to the radially outer working space, “inner” and “outer” being defined with respect to the stop spring.

  • Patent number: 7077248
    Abstract: Suspension strut unit comprising a connector bearing for piston rod of the suspension strut unit, a spring plate for a vehicle spring, and a first has a bearing with a bearing input part on the spring plate side and a bearing output part on the connector bearing side, which bearing allows relative rotational movement between the vehicle spring and the connector bearing of the piston rod. After the piston rod has traveled inward a certain distance, the cylinder is supported against the connector bearing by way of a stop buffer. A second bearing allows relative rotational movement between the connector bearing and the cylinder when the stop buffer is active; the second bearing is located functionally between the stop buffer and the connector bearing, and a functional separation is present between the bearing input part for the spring plate and the second bearing.
