Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/001859
Kind Code:
A1
Abstract:
Provided is a power transmission device capable of reaching a target point when changing gears, more rapidly than conventionally possible. The power transmission device comprises an input unit, an output shaft, a lever crank mechanism, a one-way rotation-prevention mechanism, and a control unit. The lever crank mechanism comprises a rotation radius adjustment mechanism capable of freely adjusting the rotation radius. The control unit comprises a gear shift method determination unit that determines either: fixed range gear shifting whereby gear shift occurs within a fixed range; or idle range gear shifting whereby gear shift occurs within the idle range, approaching a target point. The gear shift method determination unit selects fixed range gear shifting if a determination has been made that a force has been applied to the rotation radius adjustment mechanism, said force being in the reduced diameter direction in which the rotation radius is reduced by the reduced radius force determination unit.
