Abstract (en)

[origin: DE19639376C1] Disclosed is an automatic clutch intended for an engine-transmission unit in a vehicle. When in the closing stage, the clutch works under contact overpressure conditions, so that the torque transmitted by the clutch is higher by a set quantity than the engine generated torque. At low external temperature, the contact overpressure is reduced, resulting in a shorter clutch adjustment path and in less energy being required for clutching, thereby compensating for the greater stiffness of the clutch control element.
