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： An automatic dual-clutch transmission is able to establish a parking lock by bringing one of a first input shaft and a second input shaft into engagements with a low speed stage gear train as well as with a reverse stage gear train in performing a parking. Gears of an engaging member and a mating sleeve in at least one of a low speed stage shift clutch and a reverse stage shift clutch which are simultaneously brought into engagements to establish the parking lock are able to mesh with each other at axially extending side surfaces thereof which are formed to extend linearly in parallel to an axial direction thereof.
