Abstract
Gearbox comprising a first clutch-hub having gear-teeth and a coaxial hollow wheel also with gear-teeth, connected to, but not rotating upon, a second clutch hub, and also having a planetary gear in part engagement with the gear-teeth and an adjustable transmission-shaft. The latter is adapted to be adjusted, by means of an adjusting device, in such a manner that the clutch-hub and the hollow wheel rotate selectively, either at rotational speeds between which there is a predetermined difference, or in synchronism. In a known gearbox of this kind, the planetary gear is arranged eccentrically upon the transmission-shaft, causing relatively considerable imbalance and relatively high bearing loads at high rotational speeds. In order to overcome this problem, and to achieve a simple design, especially of the transmission shaft, the invention proposes that the first clutch-hub comprise a radially spaced, internally toothed ring, creating an annular space. Arranged at least partly in this annular space is the transmission-shaft and the internally-hollow, coaxially arranged planetary gear.
