<p>A drive train of a motor vehicle including an internal combustion engine, a transmission which is connected to an axle drive and has a variable transmission ratio, and an automatic engine clutch located in the flow of power between the engine and transmission, is designed as an actively engagable friction clutch and transmits torque which can be controlled by a pressure medium. To improve control and a faster response the engine clutch does not include a pressing spring but has a pressing apparatus actuated by a pressure medium. The pressing apparatus is connected to a pressure medium source such that the engine clutch is engaged when in a non-actuated state by applying maximum pressure to the pressing apparatus and is disengaged, at least partially, in an actuated state, to lower clutch torque transmission or for disengaging the engine clutch by applying a reduced active pressure to the pressing apparatus.</p> |
