Continuously variable transmission

A powertrain assembly, comprising:

• a prime mover, comprising a crankshaft and a crankcase;
• and
• a clutch, comprising:
• a housing coupled to the crankcase and including an opening defined about an axis of rotation of the crankshaft, a first bearing positioned within the housing;
• an input subassembly coupled to a flange of the crankshaft, wherein a second bearing is disposed within the input subassembly about the axis of rotation;
• and
• an output subassembly comprising an output shaft that extends through the opening, wherein the output subassembly is supported by the first bearing of the housing and the second bearing of the input subassembly, and each of the first bearing and the second bearing are positioned radially outwardly of the output subassembly.

A powertrain assembly, comprising:

• a prime mover, comprising a crankshaft and a crankcase defining an outer profile, and wherein a flange of the crankshaft is positioned within the outer profile;
• and
• a clutch, comprising:
• a housing coupled to the crankcase and including an opening defined about an axis of rotation of the crankshaft, a first bearing positioned within the housing;
• an input subassembly coupled to the flange of the crankshaft within the outer profile, wherein a second bearing is disposed within the input subassembly about the axis of rotation;
• and
• an output subassembly comprising an output shaft that extends through the opening, wherein the output subassembly is supported by the first bearing of the housing and the second bearing of the input subassembly.

A vehicle, comprising:

• a frame;
• a plurality of ground-engaging members supporting the frame;
• and
• a powertrain supported by the frame and operably coupled to the plurality of ground-engaging members, the powertrain comprising:
• a prime mover including a crankcase and a crankshaft positioned entirely within the crankcase, the crankshaft extending along a rotational axis and defining a crankshaft oil passageway;
• a clutch operably coupled to the crankshaft of the prime mover, the clutch including an input shaft coupled to the crankshaft and an output shaft selectively coupled to the input shaft, and wherein the clutch is supported by at least a first bearing, the clutch defining a clutch oil passageway fluidly coupled to the crankshaft oil passageway and operable to direct fluid over a second bearing disposed between the input shaft and the output shaft and toward the first bearing;
• and
• a continuously variable transmission operably coupled to the clutch, the continuously variable transmission including a continuously variable transmission housing, a drive clutch positioned within the continuously variable transmission housing and a driven clutch positioned within the continuously variable transmission housing, and the drive clutch is supported independent of the continuously variable transmission housing.
