  • Patent number: 8091451
    Abstract: The invention relates to a power divider for motor vehicles, comprising a housing (1), a primary shaft (2) having a drive connection to a first driven axis, a controlled friction coupling (4) and a displacement drive (6, 7, 8) for the drive of a second driven axis. The friction coupling (4) can be actuated by means of two ramp rings (1, 16) which can rotate counter to each other and which comprise articulated jacks (19, 20). In order to use the toothed wheels as a displacement drive and to provide a compact and economical actuator, the control curves are embodied on a control cam (25) which comprises two control sliding tracks (35, 36) which are offset in relation to each other and can be rotated about a parallel axis in relation to the axis of primary shaft (2). The control cam (25) is rotationally mounted on the second toothed wheel (7) or the shaft thereof (9).
