Is provided herein a torque-limiting electronically controlled CVT comprising a drive portion having a drive pulley including two opposed sheaves adapted to be actuated with an electric motor to set a transmission ratio between an engine and a ground contacting rotating member of a vehicle, an input module adapted to receive a signal indicative of whether a ground-contacting rotating member is airborne, a processing module adapted to determine a desired CVT ratio, and an output module adapted to actuate the electric motor to obtain the desired CVT ratio to match the circumferential velocity of the vehicle's airborne ground-contacting rotating member with the speed of the vehicle in order to limit a mechanical peak torque sustained by a drive system of the vehicle. Also provided hereby is a vehicle equipped with the CVT, a kit including such a CVT and a method of managing the CVT to limit the mechanical peak torque sustained by a drive train of a vehicle.

摘要:
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.
