Abstract
A transmission includes a primary drive gear fixed to an input shaft and an idler gear meshing with the primary drive gear. A transmission pump is arranged to receive power from the idler gear. A power take-off unit is mounted to a case of the transmission and includes an input shaft having a first gear meshing with the idler gear and a second gear. An output shaft has a third gear meshing with the second gear.
Claims18
A transmission comprising:
- a case;
- an input shaft;
- a primary drive gear fixed to the input shaft and having a first set of gear teeth;
- an idler gear having a second set of gear teeth in meshing engagement with the first set of gear teeth;
- a transmission-pump drive gear having a third set of gear teeth in meshing engagement with the second set of gear teeth to transmit power from the idler gear to a transmission pump;
- and
- a power take-off unit (PTU) mounted to the case and including:
- a PTU input shaft,
- a PTU output shaft,
- a first unit gear disposed on the PTU input shaft and having a fourth set of gear teeth in meshing engagement with the second set of teeth to transmit power from the idler gear to the PTU input shaft,
- a second unit gear disposed on the PTU input shaft and having a fifth set of gear teeth, and
- a third unit gear disposed on the PTU output shaft and having a sixth set of gear teeth in meshing engagement with the fifth set of gear teeth to transmit power from the PTU input shaft to the PTU output shaft.
