ABSTRACT:
A driving pulley used in a variable speed transmission is adapted to receive a trapezoidal belt by which power is transmitted from the driving pulley to a driven pulley. The driving pulley is provided with radial pins connected to the shaft and movable inside respective apertures delimited by ramps for limiting sliding and rotating movements of the movable flange within predetermined limits with respect to the shaft and for imposing a specific mechanical behavior to the movable flange. It allows additional control of the engine speed under full throttle, reducing the overrun and helping the transmission return to its smallest ratio during a quick vehicle slowdown.
