Abstract: The present invention relates to a power transmission device including two or more pistons. The power transmission device may include: a housing arranged to form a mounting space by connecting a clutch housing, a clutch connecting portion, a clutch hub and a disk housing to each other; a power transmission hub selectively and operably connected to the housing; a plurality of first friction disks splined to an interior circumference of the disk housing; a plurality of second friction disks splined to an exterior circumference of the power transmission hub and disposed alternately with the first friction disks; a piston module including two or more pistons, each of which has a corresponding piston chamber, and selectively and frictionally coupling the first friction disks with the second friction disks by an operating hydraulic pressure supplied to the piston chambers; and at least one return spring or at least one separating spring supplying a spring load counteracting against an axial force generated by the operating hydraulic pressure, and disposed at an inside or an outside of the piston module, wherein friction material is attached to any one surface or both surfaces of each first friction disk or each second friction disk.

Abstract: The present invention relates to a drive axle assembly for an industrial vehicle comprising a support structure containing a differential. The unit comprises a first axle shaft (10') connected to a first driven shaft (9') of the differential by means of a reduction gear (20') and a axle shaft (10') connected to a second driven shaft (9'') of the differential by means of a second reduction gear (20' ' ). Such reduction gears (20', 20'') are configured in order to take at least a first operating condition and a second operating condition wherein they respectively actuate or do not actuate a speed reduction.

Abstract: The invention relates to a device for disengaging a clutch, in particular a clutch in the drive train of a motor vehicle, comprising a housing that is arranged concentrically about an axis and forms a pressure chamber in which an axially movable annular piston is arranged and a disengagement bearing that is designed for abutment on a disc spring of the clutch and is fastened to the annular piston, the housing being supported via a cover bearing on a cover of the clutch, wherein the cover bearing has a stationary inner ring, a rotating outer ring, and rolling elements arranged therebetween. The invention is characterised in that the disengagement bearing is arranged substantially within the inner ring of the cover bearing at least during part of an actuating stroke of the annular piston.
