What is the principle of a CVT transmission?
1 Answers
The principle of a CVT transmission: In its transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the smaller pulley, which drives the larger pulley via the steel belt. A CVT mainly consists of two sets of pulleys (drive pulley and driven pulley), a transmission belt (steel belt), an oil pump, a torque converter, actuators (valve body, oil circuit), sensors, a computer, and other components. CVT directly translates to "continuously variable transmission," commonly known as a stepless transmission. It does not have specific fixed gear ratios, and its operation is similar to an automatic transmission. However, the variation in speed ratios differs from the gear-shifting process of an automatic transmission—it is continuous, ensuring smooth and uninterrupted power delivery.
