Motorcycle including centrifugal clutch

摘要

A centrifugal clutch is disclosed. The centrifugal clutch has a first plate provided in a clutch housing, a second plate provided in a clutch boss, a pressure plate capable of being moved close to and away from the first and second plates, and a centrifugal weight arranged to push the pressure plate toward the first and second plates by receiving centrifugal force. The centrifugal clutch is arranged so that torque T transmitted between the first and second plates is temporarily reduced and then increased as an engine rotational speed is increased from a time when an engine is stopped.

主权项

1. A motorcycle comprising:
an engine; a driving wheel; a first power transmission mechanism connected to the engine; a second power transmission mechanism connected to the driving wheel; and a centrifugal clutch connected to the first and second power transmission mechanisms, the centrifugal clutch including
a first rotator connected to the first power transmission mechanism;a second rotator connected to the second power transmission mechanism;a first plate that is provided in the first rotator and that rotates together with the first rotator;a second plate that is provided in the second rotator, the second plate facing the first plate and rotating together with the second rotator;a pressure plate facing one of the first plate and the second plate, the pressure plate being movable both toward and away from the first and second plates; anda centrifugal weight disposed opposite to locations of the first and second plates with respect to the pressure plate, the centrifugal weight pushing the pressure plate toward the first and second plates by receiving centrifugal force; wherein the torque transmitted between the first and second plates is temporarily reduced and then increased when an engine rotational speed is increased during an engine operation period following a time period during which the engine is stopped.
