The invention provides a CVT hybrid power transmission structure, and belongs to the technical field of automobile hybrid power transmission. The technical problems that an existing hybrid transmission system is few in driving mode and large in size and weight are solved. The CVT hybrid power transmission structure comprises a shell and an engine, wherein a motor, an inner gear ring and a CVT driving belt wheel are arranged in the shell; a transmission shaft for transmitting power of the engine is arranged outside the engine; the inner gear ring is in transmission connection with the CVT driving belt wheel; a sun gear is fixedly arranged at the output end of the motor; the sun gear and the inner gear ring are coaxially arranged; a frame body is arranged on the transmission shaft; a planetary gear is rotationally connected to the frame body and meshed with the inner gear ring and the sun gear at the same time; the inner gear ring is coaxially and fixedly connected with the CVT driving belt wheel; a brake capable of fixedly connecting the transmission shaft with the shell in a joint mode is arranged on the shell; and a clutch used for fixed connection is arranged between any two of the frame body, the inner gear ring and the sun gear. Three driving modes can be achieved through the single motor, and the structure is compact.

    本发明提供了一种CVT混合动力传动结构,属于汽车混动传动技术领域。它解决了现有混动传动系统驱动模式少且体积和重量大的技术问题。本CVT混合动力传动结构包括壳体和发动机,壳体内设有电机、内齿圈和CVT主动带轮,发动机外设有用于传递发动机的动力的传动轴,内齿圈与CVT主动带轮传动连接,电机的输出端固设有太阳齿轮,太阳齿轮与内齿圈同轴布置,传动轴上具有框架体,框架体上转动连接有行星齿轮,行星齿轮同时与内齿圈和太阳齿轮啮合,内齿圈与CVT主动带轮同轴固连,壳体上设有能将传动轴与壳体接合固连的制动器,框架体、内齿圈和太阳齿轮中任意两个之间设有用于接合固连的离合器。本发明通过单电机可实现三种驱动模式且结构紧凑。
