CRANKING DEVICE FOR INTERNAL COMBUSTION ENGINES

摘要

A cranking device for internal combustion engines has a permanent excitation cranking motor and an electrical coasting brake provided with a switch (25) which mutually connects during the coasting phase of the cranking device the connecting lines of the brushes (4, 4') of the cranking motor (1) by means of a resistance (24). In particular, an additional winding of the clutching relay (15) of the cranking device is used as a resistance. The cranking device is characterized by the fact that the cranking motor quickly stops without mechanical braking devices after a starting procedure. In this way, the pinion (10) can disconnect from the corresponding toothed wheel (11) of the internal combustion engine, come quickly to a stop then engage once again the toothed wheel without problems even in the case of starting procedures that quickly follow each other.
