Abstract

An automatic transmission (1) is described, having a variator (5) that comprises at least two conical disk sets (2, 3), such that a wrap-around element (4) is guided via the conical disk sets (2, 3) for torque transmission with continuous variation of the transmission ratio. In this, the arrangement of the rotation axes of two conical disks of at least one conical disk set relative to one another can be varied.
