POWER NORMAL/REVERSE ROTATION CONVERTER, HUMAN POWER MOVEMENT DEVICE EQUIPPED WITH IT, OR UNIDIRECTIONAL CLUTCH ELEMENT EQUIPPED WITH UNLOCKING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a power normal/reverse rotation converter capable of very efficiently converting power generated by rotating/rocking a pedal crank or the like to continuous rotative power; and a human power movement device equipped with it.;SOLUTION: This power normal/reverse rotation converter is composed of: a rotative power input shaft; a unidirectional clutch element A connected to the rotative power input shaft and capable of transmitting power only in a rotation direction A; a unidirectional clutch element B connected to the rotative power input shaft and capable of transmitting power only in a rotation direction B; and a planet gear mechanism composed of a ring gear connected to the unidirectional clutch element A with power transmitted only in the rotation direction A, a sun gear connected to the unidirectional clutch element B with power transmitted only in the rotation direction B, a planetary carrier with rotation braked in an optional time, and a planetary gear journaled to the planetary carrier.;COPYRIGHT: (C)2009,JPO&INPIT
