Abstract
Abstract A reverse drive for small vehicles in which an output shaft of a starter motor disposed independently of a driving internal combustion engine can be coupled to a power transmission system between the internal combustion engine and a rear wheel in such a way that the rear wheel is driven in the reverse direction. The starter motor may be capable of normal and reverse rotations, the normal rotation of the starter motor being transmitted to the internal combustion engine through a starting clutch, and the reverse rotation of said starter motor being transmitted to the power transmission system through a reverse clutch. Otherwise, the starter motor may be capable of rotating only in one direction. In this case, the output of the starter motor is transmitted to the output side of the power transmission system through a reverse transmission line while the power transmission system is interrupted.
