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.
一种车辆的动力系统,所述动力系统包括具有驱动轴(11)的电动机(16),其中所述驱动轴优选地被定向成垂直于所述动力系统旨在驱动(即旋转)的车轮(18)的公共轴线(AW)。所述电动机的驱动轴通过具有至少一对配合齿轮(12、14)的变速器(10)机械连接到与所述公共轴线对齐的车轮的轴(20、22),优选地,一对配合齿轮中的一个是偏置小齿轮(14),并且变速器的减速比在约6至约15的范围内,小齿轮具有2至6个齿。
