Gear change box arrangement for an internal combustion engine comprises a third gear element of a pick-off gear brought in the driving region for reverse travel by a switch element

摘要

Gear change box arrangement comprises an infinitely variable toroidal gear (12), a planet wheel pick-off gear (13) and a planet wheel reverse gear (14) arranged between a central input shaft (10) and a coaxial output shaft (11). In the driving region for reverse travel the third gear element (21) of the pick-off gear is brought by an associated additional switch element (KR) into a drive connection with the second gear element (24) of the reverse gear rotating in the opposite direction to the output shaft. An Independent claim is also included for an alternative gear change box arrangement.
