Cone clutch system

A cone clutch assembly comprising:

• an inner cone member configured to be rotationally coupled to a first shaft, the inner cone member defining a first friction surface;
• an outer cone member configured to be rotationally coupled to a second shaft, the outer cone member defining a second friction surface opposing the first friction surface;
• and
• wherein the inner cone member and outer cone member are configured to be selectively engage and disengaged from each other,
• wherein, 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, and
• wherein an 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, wherein the cone clutch assembly is configured such that the inner surface of the inner cone member defines a non-friction surface when the inner cone member is engaged with the outer cone member to transfer rotational motion between the inner cone member and the outer cone member, and wherein the non-friction surface does not frictionally engage an opposing surface when the inner cone member is engaged with the outer cone member to transfer rotational motion between the inner cone member and the outer cone member.
