Driving mechanism for driving e.g. vacuum pump shaft of internal combustion engine of motor vehicle, has driving unit and pinion to drive respective driven shafts, where driving unit has bell fixing pinion on drive shaft

摘要

The mechanism has a driving unit to drive a driven shaft and comprising a bell (3) and a constant velocity joint, and a pinion (7) to drive another driven shaft. The pinion is arranged between a drive shaft (1) and the bell (3) which fixes the pinion on the drive shaft. The pinion is drilled for permitting the passage of a threaded end (3a) of the bell, where the end is housed in a coaxial thread of the drive shaft.
