Manual and automatic transmissions have several fixed transmission ratios, while the advantage of a continuously variable transmission is that the transmission ratio varies continuously within a certain range. The maintenance of the infinitely variable transmission adopts a transmission belt and a variable working diameter driving and driven wheel to transmit power in combination. Due to the continuous change of transmission ratio achieved by CVT, the optimal matching between the transmission system and engine operating conditions can be achieved, thereby improving the fuel economy and power performance of the car, as well as improving the driver's handling convenience and riding comfort.
 

自动变速系统主要由主动轮组、从动轮组、金属传动带和液压控制系统及电子控制系统等组成。主动轮组和从动轮组都由固定盘和可动盘组成，固定盘在轴上固定不动，而可动盘在液压控制系统的控制下可以沿轴向移动。可动盘与固定盘都是锥面结构，他们各自的锥面共同形成V型槽来与V型金属传动带啮合。

The automatic transmission system mainly consists of an active wheel group, a driven wheel group, a metal transmission belt, a hydraulic control system, and an electronic control system. The driving wheel group and the driven wheel group are both composed of a fixed disc and a movable disc. The fixed disc is fixed on the shaft and cannot move, while the movable disc can move axially under the control of the hydraulic control system. Both movable and fixed discs have a conical structure, and their respective conical surfaces together form a V-shaped groove to mesh with the V-shaped metal transmission belt.

The metal transmission belt for maintenance of a continuously variable transmission is composed of two bundles of metal rings and hundreds of metal plates.

发动机输出动力传递到CVT的主动轮，然后通过V型金属传动带传递到从动轮，经减速器、差速器传递给汽车驱动轮。CVT变速是由液压控制系统控制主动轮与从动轮的可动盘作轴向移动来改变主动轮、从动轮锥面与V型传动带啮合的工作半径，从而改变传动比，从而实现了无级变速。

The engine output power is first transmitted to the driving wheel of the CVT, then to the driven wheel through a V-shaped metal transmission belt, and finally to the driving wheel of the car through a reducer and differential. CVT transmission is a hydraulic control system that controls the axial movement of the movable discs of the driving and driven wheels to change the working radius of the engagement between the cone surface of the driving and driven wheels and the V-shaped transmission belt, thereby changing the transmission ratio and achieving stepless transmission.

在金属带式无级变速器的液压系统中，从动油缸的作用是控制金属带的张紧力，以保证来自发动机的动力、可靠的传递。主动油缸控制主动锥轮的位置沿轴向移动，在主动轮组金属带沿V型槽移动，由于金属带的长度不变，在从动轮组上金属带沿V型槽向相反的方向变化。金属带在主动轮组和从动轮组上的回转半径发生变化，实现速比的连续变化。

In the hydraulic system of a metal belt continuously variable transmission, the function of the slave cylinder is to control the tension of the metal belt to ensure efficient and reliable transmission of power from the engine. The active oil cylinder controls the position of the active cone wheel to move axially, and the metal belt in the driving wheel group moves along the V-shaped groove. Due to the constant length of the metal belt, the metal belt on the driven wheel group changes in the opposite direction along the V-shaped groove. The turning radius of the metal belt on the driving wheel group and the driven wheel group changes, achieving continuous changes in speed ratio.

汽车开始起步时，主动轮的工作半径较小，变速器可以获得较大的传动比，变速器获得较大的减速。随着车速的增加，主动轮的工作半径逐渐减小，从动轮的工作半径相应增大，CVT的传动比下降，变速器输出转速升高，使得汽车能够以更高的速度行驶。

When the car starts to start, the working radius of the driving wheel is small, and the transmission can achieve a larger transmission ratio, resulting in a greater deceleration. As the speed increases, the working radius of the driving wheel gradually decreases, and the working radius of the driven wheel correspondingly increases. The transmission ratio of the CVT decreases, and the output speed of the transmission increases, allowing the car to travel at higher speeds.
