A power divider for motor vehicles includes a housing, a primary shaft and a secondary shaft, wherein a friction clutch having an outer part that is rigidly connected to the primary shaft, and an inner part, derives torque from the primary shaft and delivers the torque to the secondary shaft by means of the inner part and a displacement drive. To ensure a sufficient supply of lubrication oil under all conditions, an oil reservoir, which at least partially surrounds the ramp ring, is fixed in the housing between the coupling and the displacement drive. The base of the oil reservoir comprises at least one opening, which is adjacent to the upper part of the periphery of the ramp ring, and the oil reservoir has at least one guiding device that extends into the centrifugal area of the displacement drive, through which the centrifuged lubrication oil is received in the reservoir.
