ABSTRACT:
The crown wheel of a planetary gear is connected to an input shaft while the planet carrier is connected to the output shaft. The sun wheel is locked by means of a free wheel when the clutch is released. The device then operates as a reduction gear. The sun wheel rotates with the crown wheel and the planer carrier when the clutch is engaged. The axial forces (F.sub.AP, F.sub.AC), sustained by the sun wheel and the crown wheel when in gear-reduction mode, and resulting from the helical tooth configuration, tend through the stop to compress a spring and release the clutch. When in direct drive and beyond a certain torque, the clutch slips, thereby generating the above-mentioned axial forces which compress the spring and accelerate disengaging. The device operates as a reduction gear until the torque on the shaft is reduced, thereby, enabling the spring to re-engage the clutch. For use on the input side of a gear box in order to automatically reduce speed ratios during acceleration, the gear box being itself preferably automatically controlled, especially under the effect of axial forces generated by other planetary gears.
