Problems solved by technology
[0002] At present, the automatic transmission that is used more in automobiles is the automatic transmission that combines the hydraulic torque converter and the planetary gear system, but it has obvious disadvantages: the mechanical structure and the control system are complex, the transmission ratio is discontinuous, and the power Large loss, low efficiency, high maintenance and repair costs
Another continuously variable transmission (CVT), which uses a metal transmission belt and changes the matching diameter of the driving and driven wheels to achieve speed change and power transmission, but the weakness of CVT is that the metal belt has a small carrying capacity, limited transmission power, and high cost. short life
In addition, due to its rather complex control system, the auxiliary cost increases
Therefore, the continuously variable transmission (CVT) is currently only available in low-emission vehicles
