In some examples, a cone clutch assembly includes an inner cone member rotationally coupled to a first shaft, the inner cone member defining a first friction surface, and an outer cone member rotationally coupled to a second shaft, the outer cone member defining a second friction surface opposing the first friction surface. The inner cone member and outer cone member are configured to be selectively engage and disengaged from each other. When the inner cone member is engaged with the outer cone member, the first friction surface of the inner cone member frictionally engages the second friction surface of the outer cone member such that rotational motion is transferred between the inner cone member and the outer cone member. The inner surface of the inner cone member opposing the first friction surface includes at least one groove configured to receive a cooling fluid during operation of the cone clutch assembly.
