ANTRIEBSANORDNUNG VON HILFSEINRICHTUNGEN FUER EINE BRENNKRAFTMASCHINE.

摘要

A device which drives accessories such as an alternator or a cooling water pump utilizing output of an automobile engine, includes an input shaft installed to an output shaft of the engine, a continuously variable transmission with differential planetary mechanism of the frictional transmission type installed between the shaft and a pulley connected to the accessories, and a pressure adjusting device for adjusting the pressure of the frictional transmission oil retained in an annular chamber enclosing the continuously variable transmission. The pressure adjusting device is connected in communication with the annular chamber and includes bleed holes for providing a free liquid surface of the frictional transmission oil so that variation in pressure of the frictional transmission oil is absorbed by the vertical movement of the free liquid surface.
