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.

High-voltage connection device for an electrorheological device

The invention relates to a vibration damper arrangement, in particular for damping compression and rebound forces on motor vehicles, which comprises a pressure medium cylinder (), in which a piston () with a piston rod () is guided axially displaceably, which piston () divides the pressure medium cylinder () into a compression chamber () and a rebound chamber (), a gas pressure accumulator () also being provided for volume compensation of the piston rod (), which gas pressure accumulator () is connected to the compression chamber () by way of at least one first check valve () which can open toward the compression chamber (), and a second check valve () which can open toward the rebound chamber () and, parallel thereto, at least one first controllable operating valve () being provided between the compression chamber () and the rebound chamber ().

Vibration damper arrangement

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.

A system and method for an electromechanically actuable parking brake for motor vehicles, which is embodied as a drum brake of the 'duo-servo' type. The parking brake has a brake actuating device which can be actuated by an electromechanical actuator, is designed as an expander element and acts on two brake shoes, the expander element being supported via a spring energy storage device, may be designed as a diaphragm spring assembly, and being spreadable by a predetermined length of travel, when the parking brake is actuated, to apply an application force. In order to provide a sufficiently large hot parking travel, the length of travel travelled by the expander element to apply the application force when the parking brake is actuated can be moved as a function of at least one motor vehicle state parameter.
