Abstract: The present invention relates to a device for a transmission, comprising a summing planetary gear set (17) and a variator unit (13) and components that bring them into operative connection with each other and with an input shaft (1) and output shaft (3, 8) for influencing the output speed in a continuously variable manner at constant input speed. The device can be installed as a prefabricated module between an internal combustion engine and a conventional transmission of any configuration and is also suitable for splitting the drive power of an internal combustion engine among a vehicle drive and one or several power take-offs, with the speed of the vehicle drive and/or the speed of the power take-off being adjustable in a continuously variable manner by the device. The device is also suitable for retrofitting existing motor vehicles.

Abstract: A superposition transmission in several variants and embodiments has hydrostatic-mechanical or electric-mechanical power splitting for the use in vehicles and work machines such as municipal vehicles, handling devices such as telehandlers or forklifts, wheel loaders, tractors and comparable apparatuses, in which an infinitely variable adjustment of the gear ratio is desired independent of the speed of the drive engine. The input shaft (1) is connected with a variator which is in operative connection with two summing planetary gears (12) and (13) arranged parallel with respect to each other. The output occurs in all driving speeds and all driving ranges via the planet carrier arranged as carrier (18).
