The side part of the input gear is hinged with a plurality of swing rods, the swing rods drive the rollers to move inwards under the action of centrifugal force and cling to the surface of the movable half shaft, so that power transmission of the input gear and the movable half shaft is realized; when the electric power system is used as main power, the torque given to the input gear by the gasoline power system is weaker or the torque is not directly input, the rotating speed of the movable half shaft is higher than that of the input gear, so that the roller is separated from the movable half shaft, the electric power system completely acts on the rear wheel hub, the load of the electric power system is minimized and only used for the rear wheel to run, and therefore the electric efficiency of the hybrid motorcycle is improved, and the endurance is stronger;

when a gasoline power system is used as power, the input gear rotates at high speed, the swinging rod locks the output gear and the movable half shaft mutually through the roller under the action of centrifugal force, the input gear and the movable half shaft cannot or cannot easily move relatively, and power transmission is realized.

The inner diameter e of the roller is larger than the outer diameter f of the pin shaft, the actual movement space of the roller is reduced due to the design, and the depth of the wedge-shaped groove can be correspondingly reduced.

When the design enables the rotating speed of the input gear to be fast, the pressing effect of the roller and the movable half shaft can be achieved without the oscillating rod, and at the moment, the main function of the oscillating rod is to forcibly move the roller under some special conditions, so that the double-insurance effect is achieved.

The spoke is arranged in the middle of the rear wheel hub, a motor housing is fixedly arranged on one side of the spoke facing a fixed half shaft, an electric energy driving cavity is formed between the motor housing and the spoke, and the outer rotor and the stator are arranged in the electric energy driving cavity; a speed reducing mechanism is arranged between the gasoline power system and the input gear, and the speed reducing mechanism and the electric power system play a role in balancing the center of gravity in the whole framework; the speed reducing mechanism is arranged in the hollow cavity of the rear rocker arm, so that the speed reducing mechanism is independently packaged to avoid interference.

At the end of the reducer, the conventional centrifugal clutch is not able to work normally (typically the lowest speed of rotation is 1000 rpm for a typical fit) due to the low speed; the swing rod has low requirement on the rotating speed, and can well achieve the effect of pressing the roller at the speed of 100 revolutions per minute (the rated rotating speed of the hub of a common electric vehicle is 250-350 revolutions per minute); moreover, the design is light in weight and has little additional burden.
