Abstract:
1. A superposition transmission for use in vehicles and work machines having wheels and an internal combustion engine, the superposition transmission comprising: a control device comprising a variator, with which direction of rotation of an output shaft driving the wheels can be changed and with which speed of the output shaft can be influenced in an infinitely variable manner; an input shaft driven by the internal combustion engine and connected via a spur-gear stage with an input shaft of the variator, said variator comprising an adjusting device having a variator output shaft; wherein the variator output shaft is connected with sun gears of mutually parallel arranged summing planetary gears either via a spur-gear stage or directly; wherein the superposition transmission outputs via a carrier arranged as a planet carrier for all planetary wheels in all driving speeds and all driving ranges; and wherein said carrier is rigidly connected with the output shaft.
