Embodiment Construction

[0027] Figures 1 to 3 The shock absorber 1 shown is a fluid shock absorber. The design and function of such a fluid shock absorber is known from DE 10 2010 029180 A1 referenced here.

[0028] The shock absorber 1 includes a housing 4 having a first housing end 2 and a second housing end 16 . The housing 4 is closed at the first housing end 2 by the guiding and sealing unit 3 . At the second housing end 16 the housing 4 comprises a second fastening element 15 . The housing 4 encloses a working space 5 and an equalization space 6 . The housing 4 has a longitudinal axis 7 . In particular, it is constructed at least partially rotationally symmetrically about the central axis 7 . The housing 4 can be of double-wall design. In particular, it comprises an inner housing 8 and an outer housing 9 . The outer housing 9 surrounds the inner housing 8 . In particular, the outer housing 9 can be arranged concentrically with the inner housing 8 . Therefore, the equalization space 6 ...

Abstract

A shock absorber comprises a housing having a work space, damping fluid present in the work space, a piston unit arranged in the work space with a piston rod having a longitudinal axis, a piston secured to the piston rod, dividing the work space into a first partial work space and a second partial work space, a flow channel connecting the first partial work space and the second partial work space, an adjustment unit for adjusting the damping force of the shock absorber with an adjustment element for adjusting the effective flow cross section area of the flow channel, an adjustment actuator for the automated adjusting of an arrangement of the adjustment element and the piston rod, wherein the adjustment unit is arranged inside the shock absorber.

Description

[0001] The content of German patent application DE 10 2016 209 824.1 is hereby incorporated by reference. technical field [0002] The present invention relates to a shock absorber. Background technique [0003] An impact absorber is known from DE 10 2010 029 180 A1. Contents of the invention [0004] The problem that the present invention proposes to solve is that of improving a shock absorber such that its damping action can be adjusted in an uncomplicated, especially automated and robust manner. [0005] According to the invention, this problem is solved by a shock absorber comprising: a housing with a working space; a buffer fluid present in the working space; a piston unit arranged in the working space, the piston unit has a piston rod comprising a longitudinal axis, a piston fixed to the piston rod, the piston dividing the working space into a first working space part and a second working space part, the communication channel separating the first working space part ...
