Abstract:
A transmission for a motor vehicle, comprising:a drive shaft, an output shaft arranged coaxially with the drive shaft with a continuously adjustable variator which has two drive toroidal disks rotating together and two output toroidal disks rotating together, and a drivetrain with an epicycloidal gear train having at least two gears, one being at least one first sun gear and another being at least one planet gear supported by at least one planet carrier, the drive toroidal disks or the output toroidal disks being torsionally fixed or connectable to the first sun gear of the epicycloidal gear train, and the disks that are unconnected to the first sun gear being torsionally fixed or connected by the at least one planet carrier of the epicycloidal gear train, wherein a second of the at least one planet gear moved by or with a first of the at least one planet gear has a diameter such that for a transmission ratio of the variator at an operating point thereof the contact point of the second planet gear with an output element of the epicycloidal gear train corresponds to the instantaneous center of the second planet gear.
