Continuously Variable Transmission in Automotive Systems

The power is transmitted through a transmission belt to a ratchet wheel that can change the width of the groove teeth, achieving the goal of variable speed. A company has proposed improvements to the CVT, using a chain as the transmission method to achieve greater torque but with higher noise. The larger the range of transmission ratio, the more advantageous it is for improving fuel economy. Therefore, the maximum transmission ratio of CVT is 7.7, indicating relatively good fuel economy performance.
