Electric drives with high reduction transmissions

A vehicle being moveable by power provided by at least one electric motor having a drive shaft, said vehicle having a pair of rotatable wheels being rotatable via power provided by said at least one electric motor, said pair of rotatable wheels being located spaced apart in a widthwise direction of said vehicle along a common axis (AW), said vehicle further comprising a transmission, said transmission providing drive reduction with defined back driving ability and 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 being located centered between the pair of wheels or at a distance (d) from the centered location, said distance (d) being equal to or lower than 50 percent of the distance from the centered location to each individual wheel of the pair and said transmission further comprising at least one output with said at least one output having an output axis of rotation and being rotatably connected to each of the pair of wheels by a respective axle, wherein said transmission has a reduction ratio in the range of 7.86 to 15, characterized in that the back driving ability, expressed as Back Driving Coefficient CBD being the ratio of back driving opposing force to back driving force, is given by CBD being lower than 0.336 while said offset pinion comprises only 2 to 5 teeth.
