VEHICLE POWER TRANSMISSION

摘要

Power transmission apparatus (46) for mechanically transmitting motive power from a rotatable input shaft (21) to a rotatable output shaft (38), the apparatus comprising a linkage (28) connecting the input shaft to the output shaft such that rotation of the input shaft can cause rotation of the output shaft, the linkage being adjustable so that the transmission ratio can be continuously varied between a forward value and a reverse value.
