EF-CVB innovation four properties reached the worlds top in the CVT technology: 1.Variable speed pitch control(unlimited multi-segment) 2.Maximum torsional torque output 3.All action points in bearing operation structure(100% bearing) 4.Fully automatic and easy to operate(100% automatic) Product Features 1.EF-CVB,a new invention system provided full automation variable pitch control functionality. 2.EF-CVB, a special designed variable pitch structure improved start-up power efficiency instead of high power consumptions in conventional mechanical gear control devices. 3.EF-CVB is capable of changing the vehicle speed ratio to zero that no longer requiring conventional clutch gears. 4.EF-CVB can maximize output torque value while the rpm is nearly zero. 5.EF-CVB transmission efficiency test result showed +/- 90% when the output torque is greater than 5 KgM. 6.EF-CVB vehicle can automatically control its start-up drive from zero to maximum speed while the engine (or motor) is at the constant speed. 7.EF-CVB is suitable for all types of vehicles especially for those requiring a high transmission torque with heavy loadings and/or while climbing slop hills. 8.EF-CVB is an innovative eco- efficiency new product. 9.EF-CVB is possible for DIY and very easy to assemble for bikes. Product Application: Suitable for all types of vehicles or heavy machinery trucks such as farming, mining, or industrial type vehicles. Especially suitable for application to those need large transmission torsional torque. In condition of EF-CVB installed in electrical vehicles: 1.Can fully supply vehicle maximum torsional torque in starting or climbing condition without concerning overheating issue. 2.After simple assembly, EF-CVB turns the most efficient, energy saving and valuable automatic vehicle.
