Abstract: The invention relates to an oil scoop assembly (2) for using in a stationary housing with machine parts, rotatable therein around a rotational axis. The oil scoop assembly comprises an oil return element (3), which can be connected to the housing and has a wiper (10) for abutting an outer face (21) of a machine part, at least one channel (6), which is supplied by the wiper (10) with oil and which ends in an annular channel (7), extending coaxially to the rotational axis A; and an oil scoop wheel (4), connectable to one of the machine parts, with a plurality of blades (24), distributed around the rotational axis A and which extend into the annular channel (7) and, when the oil scoop wheel (4) rotates relative to the oil return element (3), delivers oil from the annular channel (7). The invention relates further to a clutch arrangement (32) with such an oil scoop assembly (2).

Abstract: The invention relates to an axially adjusting device for actuating a multiple disk clutch in the drive train of a motor vehicle. Said adjusting device comprises a housing (4) with a longitudinal axis (A) and a ball ramp arrangement (1) having a support disk (17) that is axially and radially supported in the housing (4) and an axially displaceable adjusting disk (16). The supporting disk (17) is secured against rotation in the housing (4) and, in a first lateral face (23), has first ball tracks (24) of varying depth in the peripheral direction. The adjusting disk (16) can be rotatingly driven and, in a second lateral face (25) opposite the first lateral face (23), has second ball tracks (26) of varying depth in the peripheral direction. The ball tracks (24, 26) define one pair each with opposed slopes and receive one ball (27) each. The adjusting disk (16) is axially supported on the multiple disk clutch (2) and axially and radially mounted by means of the balls (27) retained in the ball tracks (24, 26).
