Speed reducer for placing between rotating shaft of electric machine and drive shaft of drive wheel of hybrid vehicle, has gear formed by pinion of idler wheel, and pinion engaged with another pinion integrated with drive shaft of wheel

摘要

The reducer has a gear integrated with a rotating shaft of an electric machine (1). A first pinion (31) is engaged with a second pinion (51) of an idler wheel (5) mounted coaxially on a drive shaft of a drive wheel. A second gear is formed by a third pinion of the idler wheel. The third pinion is engaged with a fourth pinion (61) of another idler wheel (6) mounted coaxially on the rotating shaft of the electric machine. A third gear is formed by a fifth pinion (62) of the idler wheel. The fifth pinion is engaged with a sixth pinion (22) integrated with the drive shaft of the wheel. An independent claim is also included for a hybrid vehicle comprising an electric machine.
