However, pure electric motor-driven motorcycles have the disadvantages of short cruising range, frequent charging, and long charging time; short battery life and high replacement cost; and limited by battery technology, the existing defects have not been effectively overcome. Pure fuel-powered continuously variable transmission has the disadvantages of low transmission efficiency, high fuel consumption, and weak power performance; currently, various OEMs have upgraded the power performance of fuel-powered continuously variable motorcycles, improved clutch transmission accuracy, and controlled thermal management effectiveness. Although the overall emissions, fuel consumption, power, etc. have been improved, the improvement is very limited, and the defects such as low transmission efficiency, high fuel consumption, and low power due to mechanical structure cannot be effectively solved.

[0003] Hybrid systems have been widely used in automobiles, but due to the limited space in motorcycles, hybrid systems used in automobiles cannot be used in motorcycles. In existing hybrid motorcycles, the clutches mostly use traditional mechanical clutches. Limited by the structural characteristics of the mechanical clutch, there have always been problems such as the friction plate needing to be regularly inspected and replaced due to wear, slipping due to overload resulting in reduced transmission efficiency, and complex structure with high maintenance costs. In addition, the existing clutch shaft requires an independent shaft due to the dog claw assembly structure, and the connection with the motorcycle crankshaft adopts an end face internal and external spline connection, which has low reliability. Therefore, the existing motorcycle clutch connection structure needs to be further improved. Summary of the invention

[0022] The driving plate 22 is connected to the clutch mounting shaft 11 through internal and external splines.

[0023] In the present invention, the electromagnetic clutch 2 is coaxially arranged with the engine crankshaft, and has a compact structure. The clutch mounting shaft 11 and the engine crankshaft 1 are an integral structure formed in one piece, eliminating the connection structure between the two, which can greatly improve the connection reliability between the electromagnetic clutch 2 and the engine crankshaft 1, improve the response speed, and increase the service life of the equipment; in addition, the driving sprocket 25 and the driven disc 23 are an integral structure formed in one piece, which has strong structural reliability and more stable power transmission.

[0024] The first transmission teeth 22a are evenly arranged on the end surface of the active disk 22 close to the driven disk 23, and a first snap-in groove 22b is formed between adjacent first transmission teeth 22a; the second transmission teeth 23a that are matched with the first snap-in groove 22b are evenly arranged on the driven disk 23, and a second snap-in groove 23b that is matched with the first transmission teeth 22a is formed between adjacent second transmission teeth 23a.

[0025] Specifically, first transmission teeth 22a are evenly and spaced apart on the circumferential surface of the active disk 22, and first snap-fit ​​grooves 22b are formed between adjacent first transmission teeth 22a, that is, the first snap-fit ​​grooves 22b are also evenly and spaced apart. Similarly, second transmission teeth 23a are evenly and spaced apart on the circumferential surface of the driven disk 23, and second snap-fit ​​grooves 23b are formed between adjacent second transmission teeth 23a, and the second snap-fit ​​grooves 23b are also evenly and spaced apart. When the active disk 22 is connected and coupled with the driven disk 23, the first transmission teeth 22a are embedded in the corresponding second snap-fit ​​grooves 23b, and the second transmission teeth 23a are embedded in the corresponding first snap-fit ​​grooves 22b, so that the active disk 22 and the driven disk 23 are firmly combined together, thereby realizing the transmission of force.

The elastic member 24 is preferably a spring, and the provision of the retaining ring 26 facilitates the installation of the spring.

[0027] A push ring assembly is arranged inside the coil disk assembly 21, and the push ring assembly includes an inner push ring 27 made of non-magnetic material and an outer push ring 28 made of magnetic material, and the outer push ring 28 is arranged on the outer side of the inner push ring 27.

[0028] The inner push ring 27 is provided with a step surface 27 a , and one end surface of the outer push ring 28 abuts against the step surface 27 a .

The flange bearing 4 provides radial support force to the driven disk 23, and axially limits the driven disk 23, which can improve the reliability of operation.

[0036] Working principle of electromagnetic clutch 2: When the coil disk assembly 21 is powered on, the electromagnetic housing fixing seat 21a and the push ring assembly form a closed magnetic field, generating electromagnetic force under the action of the magnetic field, and using the conical surface 28a of the front part of the outer push ring 28 to generate axial thrust, pushing the push ring assembly to overcome the elastic force of the elastic member 24 (spring) to move axially, so that the active disk 22 and the driven disk 23 are engaged through teeth, and the clutch is engaged. When the coil disk assembly 21 is powered off, the electromagnetic force disappears, and under the elastic force of the spring, the active disk 22 is reset, and the active disk 22 is separated from the driven disk 23.

[0037] The electromagnetic clutch connection structure of the present invention is suitable for hybrid motorcycles. By controlling the clutch of the electromagnetic clutch 2, various power modes of the hybrid motorcycle can be realized.
