Patent ID: 8747266

Claim:
A device for a transmission, comprising: a summing planetary gear set ( 17 ) and a variator system ( 13 ) and components which bring them into operative connection with one another and with an input shaft ( 1 ) and an output shaft ( 3 , 8 ) so as to influence an output speed thereof in a continuously variable manner at constant input speed, wherein the device is configured to be installed as a prefabricated module between the input shaft ( 1 ) of an internal combustion engine that applies drive power thereto and the output shaft ( 3 ) to a vehicle transmission and/or the output shaft to a power take-off ( 8 ), and wherein the device comprises means for splitting the drive power of the internal combustion engine among a vehicle drive and the power take-off, 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, wherein the angular momentum of the input shaft ( 1 ) is transmitted via a spur-gear stage to a ring gear ( 18 ) of the summing planetary gear set ( 17 ) and from said ring gear ( 18 ) via plane wheels ( 20 ) to a planet carrier ( 21 ) which is in operative connection with the output shaft or the power take-off ( 8 ), and the speed of the output shaft ( 3 ) or the power take-off ( 8 ) is adjustable in a continuously variable manner and independent of the speed of the input shaft ( 1 ) via the variator system ( 13 ) with hydrostatic-mechanical or electric-mechanical power splitting which is in operative connection with a sun wheel ( 19 ) of the summing planetary gear set ( 17 ).
