Rotative gearbox for driving secondary assemblies in vehicles

摘要

The gearbox has an annulus (3) with a resistive element (6). A free wheeling diode (7) is located between a sun gear and the annulus or resistive element respectively. The drive is carried out across the planet wheel support (2) and the sun gear is rotationally fixed against the motor housing (9) via a brake (10). The diode holds the annulus in the drive direction in the case when the brake is released (direct drive). The annulus or resistive element causes a transmission increase (high speed drive) when the brakes are set.
