Document Type and Number:
WIPO Patent Application WO/2013/154153
Kind Code:
A1
Abstract:
A rotation transmission element (111) capable of providing such effects as high precision, high transmission efficiency, simple configuration, ease of fabrication, low part count, reduced weight, lower cost, continuous variability of gear ratios, and mitigation of shock during turning on/off or gear shifting, wherein, when a transfer area part (142) on either the inner circumference of a transmission ring (121) or the outer circumference of a transmission shaft (141) and an overrunning clutch (131) on the other of the inner circumference of the transmission ring (121) or the outer circumference of the transmission shaft (141) coincide with each other, the transmission ring (121) and the transmission shaft (141) are in a state of clutch engagement via the overrunning clutch (131), and when the transfer area part (142) and the overrunning clutch (131) do not coincide, clutch engagement between the transmission ring (121) and the transmission shaft (141) by the overrunning clutch (131) is released.
