Abstract:
1. A multidisk oil-bath clutch comprising: a housing mounted to rotate about a longitudinal axis of rotation; at least one hub mounted to rotate about the longitudinal axis of rotation and housed inside and coaxially with the housing; a number of drive disks housed inside the housing and angularly integral with one of the housing or the hub; a number of driven disks housed inside the housing, alternating with the drive disks, and angularly integral with the other one of the hub or the housing; at least one main oil inlet into the housing located axially at a first end of the housing; at least one main oil outlet from the housing; a number of secondary oil inlets, which are formed radially through a lateral surface of the hub, and are fed by a feed conduit formed axially through the hub; a number of secondary oil outlets formed radially through a lateral shell of the housing; and an on-off valve which is connected to the secondary oil outlets, prevents oil flow through the secondary oil outlets when the clutch is activated to transmit torque between the drive disks and the driven disks, and permits oil flow through the secondary oil outlets when the clutch is released and no torque is transmitted between the drive disks and the driven disks.
