Abstract
A motor vehicle having an active damping control, which includes at least one vibration damper having a damper piston, which can be moved back and forth in a main pipe with hydraulic medium in an axial direction relative to the main pipe. The main pipe is arranged in a container pipe. An intermediate pipe is arranged between the main pipe and the container pipe. The main pipe, the intermediate pipe and the container pipe are arranged coaxially in a three-pipe damper. The damper piston is attached to an end of a piston rod.
Claims8
A motor vehicle having an active damping control, said motor vehicle comprising:
- a container pipe;
- a main pipe arranged in the container pipe;
- an intermediate pipe arranged between the main pipe and the container pipe, wherein the main pipe, the intermediate pipe and the container pipe are arranged coaxially and constitute a three-pipe damper;
- at least one vibration damper having (i) a damper piston, which is configured to be moved back and forth in the main pipe in an axial direction relative to the main pipe, and (ii) a piston rod having an end that is attached to the damper piston;
- a hydraulic end position damper;
- a central valve block disposed at an end of the three-pipe damper that faces away from the piston rod, wherein the central valve block has two damper valve devices and a connection valve block, which is configured as a separate component and comprises at least two hydraulic connections, wherein the connection valve block with the at least two hydraulic connections is arranged and aligned independently of two damper valve blocks on a base block in a package-dependent manner such that a connection of hydraulic lines is provided when the vibration damper is mounted with further components on the motor vehicle;
- a gas balance volume disposed in an annular space between the intermediate pipe and the container pipe;
- and
- an air spring housing surrounding the base block.
