Definitions

  • the swing unit-type power unit further comprising: a cylinder block combined to the crankcase to be positioned ahead of the crankcase, the cylinder block guiding a linear reciprocation motion of a piston coupled to the crankshaft with a connecting rod in a vehicle front-rear direction; and a rear wheel disposed at a rear of the crankcase and including an axle in parallel with the rotation axis of the crankshaft.
  • the crank in the crankshaft 45 includes a circular-plate shaped crank web 97, a circular-plate shaped crank web 98, and a crank pin 99.
  • the crank web 97 is continuous with a crank journal 97a coupled to the first case half body 28a with the bearing 46a.
  • the crank web 98 is continuous with a crank journal 98a coupled to the second case half body 28b with the bearing 46b.
  • the crank pin 99 is held by the crank webs 97, 98 at a position that deviates from an axial center of the crank journals 97a, 98a, and coupled to a large end portion of the connecting rod 48 in a relatively rotatable manner about an axis parallel to the rotation axis Rx.
  • the individual crank webs 97, 98 include balance weights 101 projecting from the inward surfaces at positions that deviates from the crank pin 99 about the axial center of the crank journals 97a, 98a.
  • the rotation of the crankshaft 45 is transmitted to the camshaft 87 by the action of the cam chain 91.
  • the water pump 88 discharges the cooling water in conjunction with the rotation of the camshaft 87.
  • the cooling water circulates inside the passage, deprives heat energy from the cylinder block 29 and the cylinder head 31, and radiates the heat from the radiator 85.
  • the internal combustion engine 26 is cooled.
  • the cylinder block 29 is combined to the crankcase 28 to be positioned ahead of the crankcase 28 so as to guide the linear reciprocation motion of the piston 49 in the vehicle front-rear direction. Since the rear wheel WR is positioned at the rear of the crankcase 28, even though the pulsar sensor 113 is disposed to have the layout in which the pulsar sensor 113 intersects with the cylinder axis C at the crossing angle as close to 90 degrees as possible about the crankshaft 45, the interference between the pulsar sensor 113 and the rear wheel WR is avoided.
  • the crankcase 28 can approach the rear wheel WR as close as possible.
  • the power unit 25 can be compactly configured.
