A clutch hub for a motor vehicle transmission is used for transferring torque to a driven shaft rigidly and detachably connected thereto. The hub body comprises inclined tunnels with slanted corridors providing additional rotational effect and more even fluid distribution through intake ports. The hub also comprises a frusto-conical protuberance base blocking the fluid flow from a fluid intake chamber into a clutch hub chamber.

In a motor vehicle transmission, a clutch hub having an essentially cylinder-shaped body and a wall comprising: an outer wall portion including means for releasable connection with and carrying friction disks thereon; an annular inner wall portion forming a hub center opening extending through said hub body; said annular inner wall portion having means for mounting on and transferring torque to an associated driven shaft projecting through said center opening; a plurality of circumferentially and equidistantly spaced tunnels perforating said hub body wall along and between said inner and outer wall portions without intersecting thereof; said clutch hub comprising a protuberance on one side thereof blocking an admission of hydraulic fluid flow from an intake chamber into a clutch chamber, thereby forcing said fluid to move into said tunnels; said tunnels being angled relative to longitudinal and vertical center planes of said hub body wall in order to provide a propeller-like effect increasing the fluid rotational impetus on said clutch hub body wall.
