  • Patent number: 9222524
    Abstract: A drive force transmission device includes a clutch operatively interposed between a hub member and a drum member to selectively transmit drive power therebetween. A first rotating shaft member is coupled to the hub member to rotate with the hub member. A second rotating shaft member is coupled to a separating wall part of the drum member to rotate with the drum member. A support member rotatably supports the second rotating shaft member via a bearing. The support member includes a restriction part that restricts axial movement of an outer race of the bearing. A bottom portion of the separating wall part is a radially offset towards the bearing space with respect to a top portion of the separating wall so that the bottom portion radial overlaps with the restriction part as viewed perpendicular to a rotational axis of the drum member.

  • Patent number: 9182012
    Abstract: A power transfer unit for transferring a torque comprising a first shaft configured to receive the torque from a first device, a second shaft configured to output the torque to a second device, and an activating assembly for selectively transferring the torque from the first shaft to the second shaft. The activating assembly includes a sliding cam, a rotating cam, an actuator configured to selectively rotate the rotating cam relative to the sliding cam, and an engaging gear. The gear is configured to be moved by the sliding cam between a first engaged position where the torque is transferred from the first shaft to the second shaft through the gear and a second disengaged position where no torque is transferred to the second shaft. Relative rotation between the rotating earn and the sliding cam moves the sliding earn thereby moving the gear between the first engaged and second disengaged position.
