ELECTRONICALLY CONTROLLED CONTINUOUSLY VARIABLE TRANSMISSION WITH TORQUE LIMITING SYSTEM AND METHOD THEREOF
摘要:
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.
