Abstract
A vibration damper for a chassis of a vehicle including a damper tube which is filled at least partially with damping liquid and in which a piston rod can be moved to and fro. A working piston is movable with the piston rod, by way of which working piston the interior space of the damper tube is divided into a piston rod-side working space and a working space which is remote from the piston rod. At least one additional attachment unit is connected to the damper tube in a fluid-tight manner by way of a throughflow element. The throughflow element is arranged on the damper tube in a direction which differs from the radial direction of the damper tube.
Claims20
A vibration damper for a chassis of a vehicle, the vibration damper comprising:
- a damper tube defining an interior space which is filled at least partially with damping liquid and having a damper tube axis;
- a piston rod movably disposed in the damper tube;
- a working piston connected to the piston rod, the working piston movably disposed in the damper tube and dividing the interior space of the damper tube into a piston rod-side working space and a working space which is remote from the piston rod;
- an attachment unit connected to the damper tube, the attachment unit having an attachment unit axis;
- and
- a connecting element disposed between the damper tube and the attachment unit, the connecting element including a first outlet side with a first rectangular concave surface in contact with the damper tube, and a second outlet side with a second rectangular concave surface configured to contact the attachment unit and position the attachment unit spaced apart from the damper tube and position the attachment unit axis normal to the damper tube axis,
- wherein the connecting element includes throughflow conduits extending from the first rectangular concave surface to the second rectangular concave surface and configured to permit fluid flow to and from the interior space and the attachment unit, the throughflow conduits having an orientation non-aligned with a radial direction of the damper tube, a first one of the throughflow conduits being disposed at a different longitudinal position along the damper tube axis relative to a second one of the throughflow conduits.
A connecting element for connecting a damper tube in a fluid-tight manner to an attachment unit, the connecting element comprising a first outlet side with a first rectangular concave surface configured to sealingly contact the damper tube, and a second outlet side with a second rectangular concave surface configured to sealingly contact the attachment unit and position the attachment unit spaced apart from the damper tube and position an attachment unit axis normal to a damper tube axis, and
- throughflow conduits extending from the first rectangular concave surface to the second rectangular surface and configured to permit fluid flow to and from the damper tube and the attachment unit, the throughflow conduits having an orientation non-aligned with a radial direction of the damper tube, a first one of the throughflow conduits being disposed at a different longitudinal position along the damper tube axis relative to a second one of the throughflow conduits.
