The mechanical drive is for the pressure-charging fan (1) of an ic engine, and incorporates a steplessly-adjustable drive unit (4) from the crankshaft. From the secondary pulley (5) of the latter the input shaft (9) of a speed-increasing gear is driven via a solenoid-operated clutch (6), its output shaft being coupled t the shaft (2) of a rotor (3). The gear is epicyclic (7), with an externally-cylindrical housing (13). Its input shaft works in bearings in an axial boss (16) on the housing enclosed by the clutch in the radial direction. A clutch plate (15) and the annulus (18) of the ger train are fixed to the input shaft in addition to the bearing (17). The radial dimensions of the drive assembly (5,6,7) and fan are essentially the same. |
