Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/085185
Kind Code:
A1
Abstract:
A power transmission device K comprises: a clutch member 4 that retains a plurality of driven-side clutch plates 7 which are disposed alternatingly with driving-side clutch plates 6; a centrifugal clutch means 9 that can press the driving-side clutch plates 6 and the driven-side clutch plates 7 to each other, when a weight member 10 is at an outer diameter-side position, to create a state in which a driving power of an engine E can be transmitted to a drive wheel W, and that can release the pressing force between the driving-side clutch plates 6 and the driven-side clutch plates 7, when the weight member 10 is at an inner diameter-side position, to interrupt the transmission of the driving power of the engine E to the drive wheel W; a pressing force amplification mechanism 20 that generates a second pressing force which amplifies the pressing force between the driving-side clutch plates 6 and the driven-side clutch plates 7 in a state in which a rotation force input to an input gear 1 can be transmitted to an output shaft 3; and a suppression member D that suppresses the generation of the second pressing force when a rotation number of the engine E is no more than a prescribed rotation number.
