Abstract:
A straddle-type vehicle is disclosed. The straddle-type vehicle has a planetary gear mechanism having a ring gear rotatable with a crankshaft, a sun gear, and at least two planetary gears. The straddle-type vehicle also has a planetary carrier, a rotary shaft rotating with the sun gear, an output shaft rotating with the planetary carrier, and a CVT having a primary shaft rotatable with the rotary shaft. The straddle-type vehicle further has a primary pulley, a secondary shaft rotatable with the crankshaft, a secondary pulley, and a belt. The straddle-type vehicle additionally has an actuator configured to change a transmission gear ratio of the CVT. The crankshaft, the planetary gear mechanism, the rotary shaft, and the belt-type continuously variable transmission form a cyclic power transmission passage. A centrifugal clutch is disposed within the passage.
