A vehicle powertrain includes a first power-source configured to generate a first power-source torque and a multiple speed-ratio transmission configured to transmit the first power-source torque to power the vehicle. The powertrain also includes a fluid coupling having a fluid pump shaft operatively connected to the first power-source and a turbine shaft operatively connected to the multi-speed transmission. The fluid coupling is configured to multiply the first power-source torque, and transfer the multiplied first power-source torque to the multiple speed-ratio transmission. The powertrain additionally includes a second power-source configured to generate a second power-source torque and a first torque transfer system configured to connect the second power-source to the first power-source. The powertrain further includes a second torque transfer system configured to connect the second power-source to the multi-speed transmission. A motor vehicle having such a powertrain is also envisioned.
车辆动力系包括:第一功率源,其构造成生成第一功率源扭矩;和多速比变速器,其构造成传送第一功率源扭矩,以向车辆提供动力。动力系还包括流体联接,其具有操作地连接至第一功率源的流体泵轴和操作地连接至多速变速器的涡轮机轴。流体联接构造成成倍增大第一功率源扭矩,并将倍增的第一功率源扭矩传输至多速比变速器。动力系另外包括:第二功率源,其构造成生成第二功率源扭矩;和第一扭矩传输系统,其构造成将第二功率源连接至第一功率源。动力系还包括第二扭矩传输系统,其构造成将第二功率源连接至多速比变速器。还设想了具有这样的动力系的机动车辆。
