Abstract

The invention relates to a no-shift unidirectional transmission with expansion radius, which can accelerate equally and has not the phenomena generated by former shift transmission in changing shift that former shift transmission accelerates unevenly in changing shift and residual tail gas is generated in increasing throttle. The no-shift unidirectional transmission is divided into two parts. One is the expansion machine of radius and the other is unidirectional rotating machine. By two wheels, which are rotating in opposite directions and are not rotating in the same direction permanently, the third wheel is driven to rotate in clockwise or counterclockwise single direction. The expansion machine of radius is matched with the unidirectional rotating machine to achieve the variable speed in common. The invention can be applied in traffic tools such as bicycle, vehicle and so on as the transmission system.
