  • Driving pulley for scooters and other vehicles
    Patent number: 6520878
    Abstract: The driving pulley (12) is used in a continuously variable transmission (CVT) and comprises two flanges (22,24) around which a drivebelt (20) is partially wound. The first flange (22) is fixed in translation with reference to the drive shaft (16) while the second flange (24) is movable, with reference to the first flange (22), between a distal position and a proximal position. The driving pulley (12) is provided with an arrangement which allows the return force on the second flange (24) to be maximum when the second flange (24) is at the distal position, and minimum when the second flange (24) is at the proximal position. The driving pulley (12) is also capable of being disengaged from the drivebelt (20) at a low rotation speed. This driving pulley (12) is particularly well adapted for use on a scooter.
