Motor vehicle epicyclic gearbox - has planetary pinion on eccentric meshing with driven sun wheel by internal teeth

摘要

The epicyclic gearbox has an eccentric on the driving shaft, on which a planetary pinion with two rows of gear teeth is mounted in bearings. One row of teeth meshes with an annulus fixed to the housing and the other with a sun wheel fixed to the driven shaft. The second row of teeth (109) is internal, meshing with the sun wheel (111) on the driven shaft, and the two rows of teeth are in a common radial plane. The eccentric (102) can be engaged with the driving shaft (101) by a clutch, typically of centrifugal type and incorporating a housing (11), an annular spring with balls (122), intermediate discs (120,121,123) and a clutch disc (118).PS.
