Power-train in motor vehicle, has torque transmitting mechanisms which is configured as launch clutch engaged during first gear and reverse gear, and slipped during launch of motor vehicle from stop

摘要

The power-train has an engine (6), an electric machine, and a disconnect clutch (9) connected between engine and electric machine. A transmission device (10) includes an input element (12), an output element (22), and several planetary gear sets (14,16,18,20) connected between the elements. Several torque transmitting mechanisms (24,26,28,230,32,34,63) are connected between elements and gear sets. The torque transmitting mechanisms is a launch clutch engaged during a first gear and a reverse gear and slipped during launch of the motor vehicle from a stop.
