Abstract
A wet disc clutch is force cooled by feeding a cooling liquid under pressure from locations adjacent the axis of rotation of the clutch into the region between the friction surfaces of the clutch discs through a pattern of grooves formed in at least one of the disc surfaces and comprising a plurality of radially extending distribution grooves which communicate with a helical array of cooling grooves which in turn communicate with a plurality of radially extending conveying grooves, located between the distribution grooves, and communicating with constricted outlets disposed adjacent the outer edges of the discs.
