Abstract
A hybrid transaxle permits location of a traction motor in a more favorable location, decreasing the risk of occupant injury in a vehicle collision. Axis transfer gearing moves the generator off the engine axis. This permits placing the traction motor further forward without interference with the generator.
Claims10
A hybrid transaxle comprising:
- first and second electric machines arranged on first and second axes respectively;
- a countershaft supported for rotation about a third axis and driveably connected to the first electric machine;
- and
- a planetary gear set arranged on a fourth axis and having a sun gear driveably connected to the second electric machine, a carrier fixedly coupled to an input shaft, and a ring gear driveably connected to the countershaft;
- and wherein:
- the third axis is vertically above and horizontally aft of the fourth axis;
- the first axis is vertically above and horizontally forward of the third axis;
- and
- the second axis is horizontally forward of the fourth axis.
