Abstract
A clutch apparatus includes a clutch pack having a plurality of friction disks. The clutch pack will selectively transfer torque from a torque supplying member to a first torque receiving member. The apparatus also includes a first cooling fluid inlet. At least a portion of the fluid is supplied through the first cooling inlet to a first friction surface. The apparatus further includes a second cooling inlet. The fluid is supplied through the second cooling inlet to a second friction surface. The first cooling fluid inlet will selectively supply a greater volumetric flow of the fluid than the volumetric flow of the second cooling inlet.
