摘要： A clutch plate includes first and second axially offset annular surfaces, a first angled surface extending at an acute angle from the first annular surface in a first axial direction, and a second angled surface extending at an acute angle from the first annular surface in a second axial direction, opposite the first axial direction. In some example embodiments, the clutch plate has a wet friction material fixed to the first and second annular surfaces and at least one of the first and second angled surfaces. In an example aspect, the clutch plate has a low friction wet friction material fixed to the wet friction material of the at least one of the first and second angled surfaces. The low friction wet friction material may be fixed to the wet friction material by infusion or bonding.
