DUAL MODE ELECTRIC STARTER

This article overviews existing designs of electric starters, their advantages and disadvantages. Possibility to improve specifications of on land vehicles due to increase in reliability and operation lifetime as well as prevention of vehicle startup before oil supply to friction units is considered. The essence of the proposed device is that the electric starter is comprised of DC motor with drive shaft, simple three-link planetary gearing, freewheel clutch, flywheel driving gear, solenoid switch connected to freewheel clutch, herewith, the carrier and the epi cyclic wheel body of simple three-link planetary gearing are equipped with gear rings and gear clutch. Operation of the proposed simple three-link planetary gearing in two modes is described. Technical and economical evaluation of the proposed dual mode electric starter with simple three-link planetary gearing is provided.
