Abstract:
1. A power transmitting device comprising: a first clutch member that is rotatable about an axis, the first clutch member having a set of first spline teeth that extend longitudinally along the axis; a second clutch member that is rotatable about an axis, the second clutch member having a set of second spline teeth that extend longitudinally along the axis, the second spline teeth being arranged concentric with the first spline teeth; and a clutch pack having a set of first clutch plates and a set of second clutch plates, the set of second clutch plates being interleaved with the set of first clutch plates, each of the first clutch plates having an annular body and a set of first plate teeth that are coupled to the annular body, the first plate teeth being meshingly engaged with the set of first spline teeth, each of the second clutch plates having a set of second plate teeth that are meshingly engaged to the set of second spline teeth; wherein the set of first plate teeth comprise a plurality of spring teeth and at least one locating tooth, the spring teeth on each of the first clutch plates being configured to provide a biasing force that urges a neighboring pair of the first clutch plates away from one another in an axial direction along the axis, the at least one locating tooth being configured differently from the spring teeth such that the at least one locating tooth orients its first clutch plate to the first clutch member in a manner where the spring teeth of each of the first clutch plates are disposed in rows that are disposed concentrically about the axis, wherein a quantity of the rows is equal to a quantity of spring teeth on one of the first clutch plates.
