A friction roller planetary gearing includes a first and a second sun which are axially displaceable with respect to one another and at least one of the suns is connected for conjoint rotation to a sun shaft. Stepped planets roll on the suns, on a first annulus and on a second annulus. The suns, the annuluses and the stepped planets are configured as friction rings. The second annulus is axially displaceable relative to the first annulus. A first torque-dependent axial displacement device controls a contact pressure between the suns and contact surfaces of the planets by using a torque-dependent axial displacement of at least one of the suns. A second torque-dependent axial displacement device controls a contact pressure between the annuluses and contact surfaces of the planets by using a torque-dependent axial displacement of at least one of the annuluses.
