Abstract
A powertrain system is provided that includes a first prime mover and change-gear transmission having a first input shaft and a second input shaft. A twin clutch is disposed between the first prime mover and the transmission. The twin clutch includes a first main clutch positioned between the first prime mover and the first input shaft and a second main clutch positioned between the first prime mover and the second input shaft. The powertrain system also includes a second prime mover operably connected to one of the first and second input shafts.
Claims10
A powertrain system, comprising:
- a change-gear transmission having a first input shaft and a second input shaft;
- a first prime mover;
- a twin clutch that includes a first main clutch positioned between the first prime mover and the first input shaft and a second main clutch positioned between the first prime mover and the second input shaft;
- a second input shaft clutch positioned between the first input shaft and the second input shaft to selectively fix rotation of the first and second input shafts;
- and
- a second prime mover operably connected to one of the first and second input shafts.
A powertrain system, comprising:
- a change-gear transmission having a first input shaft, a second input shaft and a rotational output member, the change-gear transmission also including a first input shaft clutch positioned between the first input shaft and the rotational output member to selectively fix rotation of the first input shaft with the rotational output member and a second input shaft clutch positioned between the first input shaft and the second input shaft to selectively fix rotation of the first and second input shafts;
- a first prime mover operably connected to one of the first and second input shafts;
- a twin clutch that includes a first main clutch positioned between the first prime mover and the first input shaft and a second main clutch positioned been the first prime mover and the second input shaft;
- and
- a second prime mover operably connected to the other of the first and second input shafts.
A transmission and clutch arrangement for a dual prime mover powertrain system, comprising;
- a change-gear transmission having a first input shaft, a second input shaft and a rotational output member, the charge-gear transmission also including a first input shaft clutch positioned between the first input shaft and the rotational output member to selectively fix rotation of the first input it with the rotational output member and a second input shaft clutch positioned between the first input shaft and the second input shaft to selectively fix rotation of the first and second input shafts;
- a twin clutch that includes a first main clutch configured to selectively transfer power between a first prime mover and the first input shaft and a second main clutch configured to selectively transfer power between the first prime mover and the second input shaft;
- and
- wherein at least one of the first and second input shaft is configured for connection to a second prime mover.
