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.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The vibration damper according to the invention will be described using the drawings, in which:

[0033] FIG. 1 diagrammatically shows a three-dimensional oblique view of a vibration damper in accordance with one embodiment of the invention,

[0034] FIG. 2 diagrammatically shows a longitudinal section of the vibration damper according to FIG. 1 in accordance with one embodiment of the invention,

[0035] FIG. 3 diagrammatically shows a side view of the vibration damper according to FIG. 1 in accordance with one embodiment of the invention,

[0036] FIG. 4 diagrammatically shows a view of the connecting element of the vibration damper according to FIG. 1 in accordance with one embodiment of the invention, and

[0037] FIG. 5 diagrammatically shows a view of connecting elements in accordance with one embodiment of the invention.

[0038] FIG. 1 diagrammatically shows a three-dimensional oblique view of a vibration damper 1 comprising a damper tube 2, a piston rod 3, a connecting rod 9 and an attachment unit 7. Throughflow elements 8, 8 (shown using dashed lines) are arranged in the connecting element 9, the damper tube 2 being connected in a fluid-tight manner to the attachment unit 7 by way of the throughflow elements 8, 8. The throughflow elements 8, 8 which are shown are arranged diagonally. The attachment unit 7 is shown at an angle of 90 in relation to the damper tube longitudinal direction.

[0039] FIG. 2 shows by way of example a diagrammatic longitudinal section of the vibration damper 1 according to FIG. 1. At that end of the piston rod 3 which protrudes into the damper tube 2, a working piston 4 which is arranged thereon is shown. The working piston 4 divides the interior space of the damper tube 2 into a piston rod-side working space 5 and a working space 6 which is remote from the piston rod. The throughflow elements 8, 8 which are shown in a dashed manner are arranged diagonally and have the same length. The attachment unit 7 is shown at an angle of 90 in relation to the longitudinal direction of the damper tube 2.

[0040] FIG. 3 diagrammatically shows a side view of the vibration damper 1 according to FIG. 1. The piston rod 3 is shown such that it protrudes into the damper tube 2 of the vibration damper 1. The throughflow elements 8, 8 which are shown in a dashed manner and connect the attachment unit 7 in a fluid-tight manner to the damper tube 2 are arranged on the damper tube 2. The throughflow elements 8, 8 are shown in a manner which is arranged at a 90 angle with respect to the longitudinal axis of the damper tube 2. The connecting element 9 which is shown comprises the throughflow elements 8, 8 and reaches, for example, from the damper tube 2 to the attachment unit 7.

[0041] FIG. 4 diagrammatically shows a view of the connecting element 9 of the vibration damper 1 according to FIG. 1. As shown, the throughflow elements 8, 8 run through the connecting element 9. The respective ends of the connecting element 9 for attaching the damper tube 2 on one side and the attachment unit 7 on the other side to the connecting element 9 are shown in each case as concave recesses. As results from the concave recesses which are shown, the attachment unit 7 can be arranged at an angle of 90 in relation to the damper tube 2.

[0042] FIG. 5 diagrammatically shows a view of connecting elements 9, 9. Each of the connecting elements 9, 9 has a throughflow element 8, 8. The connecting elements 9, 9 are of modular construction and are shown arranged above one another.
