Abstract

A drive arrangement is provided for a motor vehicle in which a hydrodynamic torque converter is installed in the transmission between an engine and a handshift gear box. The hydrodynamic torque converter is equipped with a stop clutch which is responsive to the rotational velocity of the torque converter. The stop clutch engages when the engine and the torque converter are stopped. After the engine is started, the stop clutch automatically unlocks the component parts of the torque converter, thereby allowing relative rotational movement of the engine crankshaft and the vehicle gearshaft. This arrangement provides a parking brake effect when the gearbox is shifted into a gear.
