Abstract
A powertrain of a vehicle comprising an electric motor (16) having a drive shaft (11) wherein the drive shaft is oriented preferably perpendicular to the common axis (Aw) of the wheels (18) which the powertrain is intended to drive (i.e. rotate). The drive shaft of the electric motor is mechanically connected to the axles (20, 22) of the wheels, which are aligned with the common axis, via a transmission (10) having at least one pair of mating gears (12, 14), preferably with one of the pair of mating gears being an offset pinion (14), and with the reduction ratio of the transmission being in the range of about 6 to about 15 with the pinion having 2 to 6 teeth.
Claims15
A vehicle transmission comprising an input having an input axis of rotation and at least one pair of mating gears with one of the pair of mating gears being an offset pinion having an axis of rotation (AP) defining said input axis of rotation, said transmission having a reduction ratio in the range of about 6 to about 15 and wherein said offset pinion comprises 2 to 6 teeth, said transmission further comprising at least one output with said at least one output having an output axis of rotation.
