摘要： A cooling structure of a clutch apparatus for a transmission includes a housing, a partition wall provided inside the housing, first and second chambers respectively formed inside the housing at first and second sides of the partition wall, a clutch mechanism provided inside the first chamber. A cylindrical clutch case including an opening is provided at an outer circumference of the clutch mechanism. The cooling structure further includes a first communication passage communicating with the first and second sides of the partition wall, at least one helical protrusion provided at an outer cylindrical surface of the clutch case, and a guiding cylinder provided at an outer circumference of the clutch case with a space between the helical protrusion and the guiding cylinder. The helical protrusion guides the coolant existing between the clutch case and the guiding cylinder to the first chamber from an axial end portion of the guiding cylinder.

摘要： A lubricant discharging mechanism of a clutch apparatus for a transmission, which includes the clutch apparatus having at least one clutch mechanism provided in a clutch housing defined in a transmission case and a gear train provided in a gear train housing defined in the transmission case adjacent to the clutch housing, includes a retainer, a bore, and a guide member. The retainer is provided inside the clutch housing to surround the clutch mechanism for retaining therein a lubricant for lubricating and cooling the clutch mechanism. The bore is formed at an outer circumferential portion of the retainer for discharging therethrough the lubricant lifted radially outwardly by a centrifugal force generated by a rotation of the clutch mechanism to an outside of the retainer. The guide member is connected to the retainer for guiding the lubricant discharged from the retainer towards the gear train.
