[0018] Specifically, the side of the motorcycle engine 13 is fixed to the I-shaped rotating frame 6, and the side of the I-shaped rotating frame 6 is connected to the damper 7 through the connecting column 8. In view of the vibration characteristics of the large-displacement engine, the cooperation of the damper 7 effectively improves the stability of the operation of the large-displacement engine, makes the fuel burn more smoothly, reduces the vibration of the whole vehicle, and improves the driving smoothness and driving comfort.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a large-displacement pedal motorcycle engine suspension system, two connecting ear blocks 10 are fixedly provided on the side of the motorcycle engine 13, a fixed shaft 9 is fixedly installed between the two connecting ear blocks 10, and the fixed shaft 9 is fixedly connected to the other end of the I-shaped rotating frame 6;

[0020] Specifically, the suspension system can be connected to the motorcycle engine 13 through the cooperation between the fixed shaft 9 and the connecting ear block 10 .

[0021] A plurality of shear holes 11 are equidistantly formed on the surface of the I-shaped rotating frame 6 .

[0022] Specifically, by opening the shear holes 11 on the surface of the I-shaped rotating frame 6 , the weight of the I-shaped rotating frame 6 is reduced without changing the structural strength, thereby reducing the weight of the entire motorcycle.

[0023] An auxiliary connecting piece 12 is fixedly mounted on one end of the fixed shaft 9. A through hole matching the size of the end of the connecting shaft 5 is opened at one end of the auxiliary connecting piece 12. The connecting shaft 5 is sleeved and connected to the through hole.

[0031] When the motorcycle engine 13 vibrates during operation, the vibration of the motorcycle engine 13 will cause the connected I-shaped rotating frame 6 to shake, and the shaking of the I-shaped rotating frame 6 will drive the connecting column 8 connected to the side of the I-shaped rotating frame 6 to vibrate. The connecting column 8 is connected to the damper 7, and the vibration of the connecting column 8 is reduced by the damper 7, thereby reducing the vibration of the I-shaped rotating frame 6. The stability of the I-shaped rotating frame 6 reduces the vibration of the motorcycle engine 13, making the fuel combustion of the motorcycle engine 13 smoother, reducing the vibration of the entire vehicle, and improving the driving smoothness and riding comfort.
