The invention indicates a device for damping vibrations in the drive train of a motor vehicle by means of a vibration absorber which, in coaxial arrangement with the propeller shaft of the motor vehicle, comprises an annular oscillatory mass, a supporting flange which can be fixed on the propeller shaft, and a spring body composed of an elastomer which provides the vibrational coupling of the osci...

The object of the invention is to provide waterproof sheeting made from ethylene copolymer bitumen (ECB) and polyethylene (PE) by mixing the ECB raw material with the PE raw material before extrusion. The amount of PE raw material added to the ECB raw material is between 5 and 50%, preferably between 30 and 40%. Carbon black, for UV stabilisation, can be added before extrusion.

A drive system for motor vehicles which contains a controllable freewheel element in the drive is proposed. In order to prevent the jerk which can occur when the freewheel element is switched off again, it is proposed to reduce the engine torque by way of an engine engagement control unit (23). This is preferably done shortly before reaching the synchronisation point of the drive and the output sp...

A disc brake having a brake shoe wear compensating mechanism in which the sealing gaskets for the operating chamber formed between a pair of spreading members are arranged to be elastically deformable during a brake application, so as to exert a return force during a brake release. A joining element is provided between the spreading members, which utilizes a spring and the friction connection betw...

The clutch device is suitable for intermittent or freewheeling operation of a vehicle and is particularly intended to prevent operating errors and lapses on the part of a driver when switching off freewheel operation. In this arrangement, a clutch lever (4) can be operated with the aid of a clutch pedal (18) and a controllable piston (6). A hand switch (21) for switching off the automatic freewhee...
