Abstract
A rotary damper for a motor vehicle includes at least one damper element for damping the relative movement of a first mass located on the wheel-suspension side and of a second mass located on the vehicle-body side, with at least one vibration absorber (8) being arranged on the rotary damper (1).
Claims14
A rotary damper for a motor vehicle, comprising:
- at least one damper element configured to dampen a relative movement between a first mass arranged on a wheel-suspension side of the motor vehicle and a second mass arranged on a vehicle-body side;
- and
- at least one vibration absorber arranged on the rotary damper,
- wherein the damper element has a fixed first damper part and a second damper part which is radially inwardly spaced from the first damper part so as to form a radially inner space between them, is coaxial with the first damper part, and is rotatably movable relative to the first damper part so as to apply a damping force, and
- wherein said vibration absorber is arranged coaxially with the first and second damper parts of the damper element outside of the radially inner space between the first and second damper parts of the damper element and forms an autonomous vibration system which acts in opposition to a vibration system of the damper element,
- wherein said vibration absorber is arranged radially outwardly of the first and second damper parts of the damper element.

- wherein said vibration absorber is arranged coaxially with a continuation of an axis of the first and second damper parts of the damper element outside of the radially inner space between the first and second damper parts of the damper element and forms an autonomous vibration system which acts in opposition to a vibration system of the damper element,
- wherein said vibration absorber is arranged outwardly of the first and second damper parts of the damper element as considered in an axial direction.
