Embodiment Construction

[0066] exist Figures 1 to 4 A damper 10 according to the invention is shown schematically in each case, which is embodied, for example, to adjust the damper 10 and thereby enable adjustment of the damping characteristic. For regulation, a control unit 50 can be provided, which has controllable valves for this purpose.

[0067] The damper 10 includes a cylinder tube 20 as a first tube and an outer tube 40 as a second tube. Furthermore, a third tube can be attached to the damper 10 , which serves as an intermediate tube 30 for forming the intermediate interstitial space 24 . exist figure 1 It is shown that the intermediate tube 30 has approximately the same extension as the cylinder tube 20 and / or the outer tube 40 in the longitudinal direction L of the damper 10 . However, it is also possible for the central tube 30 to only partially have the length of the cylinder tube 20 and / or the outer tube 40 (the length here corresponds to the extension in the longitudinal direction L...

Abstract

The invention relates to a damper (10) for a vehicle, comprising: a cylinder tube (20) which forms an interior space (65) for movably receiving a piston (62), an outer tube (40) which surrounds the cylinder tube (20), a central tube (30) which is arranged between the cylinder tube (20) and the outer tube (40), a control unit (50) with a controllable valve, and a middle gap space (24) between the cylinder tube (20) and the central tube (30) for providing fluid flow between the inner space (65) and the control unit (50), wherein the control unit (50) forms a passage (51) for the fluid at the central gap space (24) to provide a damping property to adjust the damper (10).

Description

technical field [0001] The invention relates to a damper (Dämpfer, sometimes also called shock absorber or muffler) according to the preamble of claim 1 of a more specifically defined type. Background technique [0002] Vehicle dampers are known from the prior art which can be adjusted actively or semi-actively with regard to their damping properties. For this purpose, the fluid flow between the various spaces of the damper, such as the working chamber and the balancing space, can be controlled. In this context, it is also mentioned that instead of a fixed characteristic curve (Kennlinie), a composite characteristic curve (Kennfeld) is used. The overall characteristic curve thus defines a region in which adjustments can be made, for example by selection by the driver of the vehicle. Such a function is used, for example, in the case of suitable undercarriages (Fahrwerk, also sometimes referred to as mobile gear or vehicle bed). For adjustment a controllable valve assembly ...
