Abstract
The present invention relates to a device for a transmission, comprising a summing planetary gear set () and a variator unit () and components that bring them into operative connection with each other and with an input shaft () and output shaft () 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.
