An infinite variable speed drive is a mechanical device capable of continuously adjusting the output speed. It achieves this through special mechanisms and transmission technologies, all without altering the input power.
The stepless variable speed drive can be categorized into various types based on different working principles, such as hydraulic transducers, CVT (Continuously Variable Transmission) units, and friction drives, among others. Among them, the CVT unit is widely applied in the automotive field.
Stepless variable speed drive, also known asTypes and Structures
Inverter drives can be categorized into various types based on different working principles, such as hydraulic gearboxes, CVT (Continuously Variable Transmission) systems, and friction drives, etc. Among them, CVT systems are widely used in the automotive industry.
Hydraulic TransmissionAdjusts speed through fluid flow and control. It utilizes a hydraulic pump and liquid as a variable speed drive (CVT).Continuously Variable Transmission (CVT), its basic principle is to achieve the conversion of input power and the adjustment of output speed by continuously varying the gear ratio or drive ratio between the input and output shafts. Compared to traditional fixed gear ratio transmission, the CVT offers greater flexibility and adaptability.

Pressurized motor, controlling the rotational speed of the output shaft by varying the supply of fluid. Hydraulic variable speed transmissions are characterized by their simple structure and high reliability, widely used in the construction and engineering machinery field.
CVT Transmission: Utilizes steel belts or chains as the transmission medium, adjusting the tension and position of the belt or chain to change the gear ratio. The CVT transmission offers smooth and continuous adjustment capabilities, allowing for stepless variable speed within a continuous range of engine speeds. It is primarily composed of basic components such as the driving wheel assembly, driven wheel assembly, metal belt, and hydraulic pump.
Friction DriveTransmits power through the contact force between frictional pairs and varies the gear ratio by altering the pressure and contact area between the friction plates. It features a simple structure and high efficiency, commonly found in small vehicles like bicycles and motorcycles.
