A vibration damper with a damper piston which is arranged in a main tube with hydraulic medium and can be moved to and fro in an axial direction relative to the main tube. The main tube is arranged in a container tube, wherein an intermediate tube is arranged between the main tube and the container tube. The main tube, the intermediate tube and the container tube are arranged coaxially in a three-tube damper. The damper piston is attached at one end of a piston rod. The three-tube damper is equipped with a hydraulic end-position damping and at its end opposite the piston rod, has a central valve block with two damper valve devices. The central valve block is partially fitted with an air spring resting on an axial support ring which is connected by a single main weld seam to the container tube and central valve block by substance bonding.

Vibration damper and motor vehicle with active suspension

An apparatus for thermal insulation on an actuating apparatus, which can be loaded with a pressure medium, of a disk brake having a piston which slides in a cylinder for the axial displacement of the brake linings against a brake disk, in particular a partially lined disk brake having an insulation body made from non-thermally conducting/poorly thermally conducting material for the insulation of the components of the actuating apparatus with respect to a brake lining. It is possible for a substantially circularly annular, metallic brake lining to be inserted into an insulation body which is made from ceramic material and separates the piston from the brake lining in a thermally insulating manner. The insulation body is configured with side faces which adjoin the circularly annular brake contact face so as to run toward the annular circumferential face in a convexly rounded manner in the direction of the piston.

Wheel for motor vehicle

To achieve a low wheel spring rate at low wheel loads and a higher wheel spring rate at higher wheel loads, each wheel of a rear-wheel suspension is equipped with a torsion bar spring which cooperates by way of a pressure rod connected with the wheel carrier. An adjusting device is connected with the torsion bar spring to act upon an additional spring element which can take up a controlled elastic position or a blocked position.

Wheel suspension

A wheel suspension system for motor vehicles has a horizontally positioned spring-and-damper unit which, by way of levers and links, interacts with wheel carriers of opposite wheels. In order to design the wheel suspension system in a favorable manner with respect to space requirements while ensuring proper functioning of its components, a horizontally positioned spring-and-damper unit and a lever, which can be swivelled about an axis which is upright or relatively slightly inclined, are provided for each side of the wheel. The lever is applied by way of a first lever section to the spring-and-damper unit and is connected, by way of a second lever section as well as a first link to one of the wheel carriers. The lever is connected to a stabilizer by way of a third lever section as well as a second link.
