Abstract
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 may be selectively engaged and disengaged from another. The inner cone member and/or the outer cone member may include a first metallic layer and a second metallic layer separated by an open structure core. The open structure core is configured to allow flow of a fluid between the first metallic layer and the second metallic layer to remove heat from the at least one of the inner cone member or the outer cone member.
Claims20
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;
- and
- 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,
- wherein the inner cone member and outer cone member are configured to be selectively engaged 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 at least one of the inner cone member or the outer cone member include a first metallic layer and a second metallic layer separated by an open structure core, wherein the open structure core is configured to allow flow of a fluid between the first metallic layer and the second metallic layer to remove heat from the at least one of the inner cone member or the outer cone member, and
- wherein the assembly is configured such that the fluid enters the open structure core via one or more inlet ports in at least one of the first metallic layer or the second metallic layer to flow between the first metallic layer and the second metallic layer.

A method of operating a cone clutch assembly, the method comprising:
- engaging an inner cone member with an outer cone member, wherein the inner cone member is rotationally coupled to a first shaft and defines a first friction surface, wherein the outer cone member is rotationally coupled to a second shaft and defines a second friction surface opposing the first friction surface,
- 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 at least one of the inner cone member or the outer cone member include a first metallic layer and a second metallic layer separated by an open structure core, wherein the open structure core is configured to allow flow of a fluid between the first metallic layer and the second metallic layer to remove heat from the at least one of the inner cone member or the outer cone member, and
- wherein the assembly is configured such that the fluid enters the open structure core via one or more inlet ports in at least one of the first metallic layer or the second metallic layer to flow between the first metallic layer and the second metallic layer.
