    摘要: Crank drive belt systems feature a triple pulley tensioner which may be applied in various ways to provide proper tensioning on belt spans adjacent a motor generator for both starting and generating functions of the system. The tensioner provides adequate belt wrap and damping functions for the systems. In a simplified embodiment, the belt system connects a crankshaft or crank pulley with a motor generator pulley and at least one accessory drive pulley, such as an air conditioner compressor. The triple pulley tensioner includes a fixed tensioner housing mounting a fixed rotatable pulley and two tensioner arms carrying pulleys for tensioning the belt spans on either side of the motor generator. The fixed pulley is positioned on a third belt span between the accessory and the crank and combines with the tensioner pulleys to maximize belt wrap around the MG pulley, the crank pulley, and the accessory pulley, if needed. Numerous alternative arrangements may be provided.

    摘要: Multi-mode operation is provided for an electrically variable transmission for a motor vehicle. The multi-mode electrically variable transmission provides for multiple gear ratios and power flow configurations including fixed gear operation. An improved input-split planetary gear set configuration is provided for the multi-mode electrically variable transmission. The multi-mode electrically variable transmission may be operated in its desired efficiency and/or performance range more frequently. Further, the transmission reduces clutch torques and provides improved functionality in range-extended electric vehicles and battery electric vehicles. The multi-mode electrically variable transmission is provided with a fixed gear operating capability for improved highway cruising and incorporates a reverse gear for reverse operation.
