ABSTRACT:
A reduction gearset for use on an electric vehicle having a motor. The reduction gearset has an input shaft, a reduction mechanism equipped with an input pinion, and a selector device for connecting the input shaft to, or disconnecting the input shaft from, the input pinion. The motor power is transmitted to the input shaft. The input pinion is rotatable relative to the input shaft. The selector device consists of a sleeve spline fit to both input shaft and input pinion. The sleeve can slide axially of the input shaft. A slidable shift shaft is mounted parallel to the input shaft. A shift fork is fixedly mounted to the shift shaft. The sleeve is made to engage the shift fork. The sleeve is moved forward or rearward by moving the shift shaft forward or rearward. Thus, the input pinion is coupled to, or uncoupled from, the input shaft.
