摘要： A hybrid power transmission mechanism includes an engine; a motor/generator having a rotor and a stator; a driven machine; a planetary gear mechanism having a sun gear, an internal gear drivingly connected to the rotor, a planetary gear, and a planetary carrier shaft including first and second extension shaft parts extending from the planetary gear in opposite directions; a first clutch switchable between a state of allowing transmission of power between the first shaft and the internal gear and a state of not allowing transmission of power therebetween; and a second clutch switchable between a state of allowing rotation of the sun gear and a state of not allowing rotation thereof. A first shaft that outputs power of the engine and a second shaft that inputs power to the driven machine are drivingly connected to the first and second extension shaft parts of the planetary carrier shaft, respectively.

摘要： An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a first gear train that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a second carrier and a clutch engagement member. The electric powertrain further includes a sun gear in the form of a ring gear and planet gears in the form of a first output shaft. To provide a compact configuration, the first electric motor and the first gear train are sandwiched between the sun gear and the planet gears.

摘要： A transmission (2) of a motor vehicle includes a first input shaft (7) for a first prime mover (3), a second input shaft (8) for a second prime mover (4), and an output shaft (9). A first sub-transmission (5) includes the first input shaft and a countershaft (11) coupled to the first input shaft (7) via a constant ratio. Gearwheels (16, 17, 18) are arranged on the countershaft, which mesh exclusively into gearwheels (12, 13, 15) arranged coaxially to the first input shaft (7). At least some of these gearwheels mesh into gearwheels (20, 21) arranged on the output shaft (9). Shift elements (A, B, C, D) are associated with the first input shaft (7) as well as with the countershaft (11), which provide either a gear with a first number of instances of gearwheel meshing or a winding-path gear with a second number of instances of gearwheel meshing. A second sub-transmission (6) includes the second input shaft (8), which is designed as a planetary transmission. A ring gear (22) forms the second input shaft (8), and a carrier (23) is coupled to the output shaft (9) via a gearwheel (14) arranged coaxially to the first input shaft (7). Shift elements (F, E) are associated with the planetary transmission, via which a sun gear (24) is fixedly connectable to the housing or the planetary transmission is bringable into direct drive. A sub-transmission coupling of the sub-transmissions is providable via one of the shift elements (A) associated with the countershaft.

摘要： The variable-speed accelerator includes an electric device, a transmission device, and a power supply portion that supplies electric power of a constant rated frequency supplied from a power supply to the electric device when the electric device is started. The electric device includes a constant-speed electric motor that rotates a constant-speed input shaft of the transmission device, and a variable-speed electric motor that functions as a generator in a generator mode and also functions as an electric motor in an electric motor mode. When starting the electric device, the power supply portion supplies the electric power generated by the variable-speed electric motor in the generator mode to the constant-speed electric motor after supplying starting power to the constant-speed electric motor and the variable-speed electric motor.
