an axially adjacent reaction plate 113 on either side thereof the reaction plates 113 and the friction plates 112 are coaxial about a center axis 126 shown in fig4 the friction plates 112 each have a splined inner circumference 128 at which they may be operatively connected with an outwardly splined shaft or hub the reaction plates 113 have a splined outer circumference 132 at which they may be connected to an inwardly splined component which may be a hub or housing the shaft connected with the friction plates 112 may rotate in which case the friction plates 112 rotate commonly with the shaft if the component is a rotatable hub the reaction plates 113 rotate with the component splined thereto in which case the disc clutch 110 is a rotating type clutch if the component is a stationary housing the reaction plates 113 are stationary with the component splined thereto in which case the disc clutch 110 is a stationary type clutch i e a brake type clutch referring to fig4 5 separating devices in the form of annular wave springs 140 are sized to contact the radially inner portion 120 of a respective one of the friction plates 112 and an adjacent respective one of the reaction plates 113 the.
