The system has a conical disk on a power input side and a pair of conical disks on an output side, each disk pair has an axially fixed disk and an axially movable disk. The disks are carried on shafts on respective shafts on the power input side and on the output side. An endless torque-transmitter extends between and passes around each disk pair for transmitting torque between them. The axially movable disk has a slide seat positioned inwardly and adjacent to its associated shaft, and an axially movable disk has a slide seat positioned radially outwardly of an inner slide seat, for minimizing axially movable disk tilting relative to its associated shaft when the transmission is under load. The axially movable pulley includes three slide seats and the radially outwardly positioned slide seat forms part of a centrifugal oil cover. The slide seats are provided on a conical disk pair on the power input side and the conical disk pair on the output side. An independent claim is included for a method for production, and a vehicle comprising such a gear system. Die Erfindung betrifft ein Automatgetriebe in Form eines Kegelscheibenumschlingungsgetriebes mit antriebsseitigen und abtriebsseitigen Kegelscheibenpaaren und einem Umschlingungsmittel zur Drehmomentübertragung, wobei der Variator steifigkeitsoptimiert ausgeführt ist.
