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.

Claim (Index 19):
The power transmission device of  claim 10 , wherein friction material is attached to any one surface or both surfaces of each first friction disk or each second friction disk, and\n wherein a ratio (k) of an outer radius (RFo) of the friction material to an inner radius (RFi) of the friction material is within a range of 1.30<k<2.20.
