Abstract: A voltage converter of a high voltage driver generates a high voltage applied to an electrorheological damper. The voltage converter and the electrorheological damper are electrically connected together through a connecting portion. The connecting portion comprises an electrode pin that connects the voltage converter and an electrode cylinder of the electrorheological damper; a ground pin that connects an external cylinder of the electrorheological damper and ground, and a ground detection pin disposed separately from the ground pin and connected to the ground through the external cylinder and the ground pin. When the ground detection pin and the ground are disconnected, the voltage converter discontinues the voltage generation with or without a command (control signal) of a sub-controller.

Abstract: A high-voltage connection device for use with an electrorheological device having a high-voltage connector with an insulating upper part, an insulating lower part, a connector socket, and a central metallic contact pin, wherein the connector socket is fixed to a grounded portion of the electrorheological device and the upper part contains ground terminal elements and is axially connected to the lower part. Additionally, the upper part has a pot-like design and coaxially surrounds both the lower part and the connector socket in the connected state.

Abstract: A high-voltage connection device for an electrorheological device (3), which comprises a high-voltage connector (1) with an insulating upper part (4), an insulating lower part (5) and a central metallic contact pin (7), wherein the lower part can be fixed in a grounded part of the electrorheological device (3) and the upper part (4) contains ground terminal elements (10) and can be axially connected to the lower part (5). The invention is characterized in that, additionally, a metal connector socket (2) is fixed on the grounded part of the electrorheological device, and in that the upper part (4) has a pot-like design and coaxially surrounds both the lower part (5) and the connector socket (2), in the inserted state.

Abstract: A vibration damper for damping spring retraction and extension forces on vehicles includes an inner pressure medium cylinder, in which a piston with a piston rod is axially slidably arranged to divide the inner cylinder into a retraction chamber and an extension chamber in which an electrorheological fluid is contained as a pressure medium. The two chambers are connected through at least one throttle gap between the inner cylinder and an electrode tube arranged coaxially thereto. The electrode tube is surrounded coaxially by an outer tube which forms a gas pressure chamber connected with the retraction chamber through a bottom valve. Axially linear or helical seals are arranged between the inner cylinder and the electrode tube, and divide the throttle gap into at least two valve partial gaps. A throttled non-return valve opens toward the gas pressure chamber between the extension chamber and the gas pressure chamber.
