Technical Field

[0001] The utility model relates to the field of continuously variable speed change, in particular to a transmission device integrating continuously variable speed change and an RV reducer. Background Art

[0002] A continuously variable transmission (CVT) is a transmission system that can continuously achieve any gear ratio within the speed range. This allows for optimal matching of the drivetrain with the engine's operating conditions. Common CVTs include hydromechanical, metal belt, and variable ramp CVTs.

[0003] RV reducer is one of the more common reducers in the worm gear reducer family. It consists of a worm and a worm wheel. It has a compact structure, a large transmission ratio, and a transmission mechanism with a self-locking function under certain conditions. It is one of the most commonly used reducers with low vibration, low noise and low energy consumption.

[0004] At present, there are many combinations of continuously variable transmissions and RV reducers, most of which are directly connected. However, there will be greater wear and tear in the process of continuously variable transmission to increase the speed, and there will be some energy loss in the process of increasing the speed, which is inconvenient to improve the transmission power. The combination of the two is not tight enough, so a transmission device integrating continuously variable transmission and RV reducer was invented to solve the problem of combining continuously variable transmission and reducer.
