Mechanical drive for a supercharger of an internal combustion engine

摘要

In a mechanical drive for a supercharger of an internal combustion engine a rotor (3) fixed on a rotor shaft (2) is driven by the crankshaft of the internal combustion engine by way of a variable speed gear (4), a solenoid-operated separable coupling (6) and a transmission. In order to create favourable overall dimensions for the supercharger drive in its axial and radial extent and a good bearing for an input shaft (9) of the transmission, the transmission is designed as planetary gearing (7), the input shaft (9) being supported in an axially projecting flange (16) of the transmission housing (13) and the solenoid-operated separable coupling (6) being arranged on the circumference of the said flange (16). It is proposed that a coupling plate (15) be arranged on one side of the said bearing (17) and on the other side an internal gear (18) on the input shaft (9).
