Embodiment Construction

[0018] figure 1 A vibration damper 1 with at least one cylinder 2 , piston rod 3 and piston 4 is shown. The piston 4 divides the working chamber of the cylinder 2 into a first working chamber 5 and a second working chamber 6 . The vibration damper 1 can also be designed differently, in particular the vibration damper 1 can be embodied as a double-tube damper with an intermediate tube, so that the first working chamber 5 and the second working chamber 6 can be connected via the hydraulic motor 7 . Depending on the pulling or pushing movement, the movement of the piston 4 in the cylinder 2 then brings about a flow of fluid from the first working chamber 5 via the hydraulic motor 7 to the second working chamber 6 or vice versa. The generator 8 is connected to the hydraulic motor 7 , and the damping force of the vibration damper 1 can also be adjusted via the generator 8 . An energizable component 9 is also located on the generator 8 . If the energizable component 9 is energize...

Abstract

A vibration damper with a piston, a piston rod fastened to the piston, a working chamber divided by the piston into a first working chamber and second working chamber, and a generator drivable by movement of the piston rod. The damping force of the vibration damper can be influenced by energization of the generator. An energizable component part is provided that short-circuits the windings of the generator when unenergized and cancels the short circuit when energized.

Description

technical field [0001] The invention relates to a vibration damper, which has a piston, a piston rod fastened to the piston, a working chamber and a generator, the working chamber is divided into a first working chamber and a second working chamber by the piston, and the generator can The drive is driven by the movement of the rod, wherein the damping force of the vibration damper can be influenced by energizing the generator. Background technique [0002] Such a vibration damper is known, for example, from US 8 392 030 B2. In a vibration damper according to US 8 392 030 B2, a generator is connected to a pump driving the generator. By energizing the generator and the pump connected to the generator, the resistance of the flowing fluid and thus the damping force of the vibration damper can also be adjusted. [0003] It is desirable that the system works without interference. In the event of disturbances in the current circuit, at least in the event of disturbances in energ...
