Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbing devices, in particular to a shock absorbing device for motorcycles. Background Art

[0002] As a common means of transportation, motorcycles must face the impact of uneven roads when driving on various road conditions, which not only affects the driver's comfort but may also cause damage to the vehicle structure. Therefore, the shock absorption system of motorcycles is one of the key components to ensure driving safety and comfort.

[0003] Traditional motorcycle shock absorbers are usually composed of a sleeve, a slide bar, and an external buffer spring. The sleeve is fixed on the motorcycle frame, the slide bar can move up and down along the slide hole in the sleeve, and the external buffer spring is sleeved between the sleeve and the slide bar to absorb and alleviate the impact force of the road surface (for example, an independent suspension shock absorber for an electric motorcycle disclosed in application No. 2024202949138). However, the shock absorption effect of this structure is still poor and needs further improvement. Utility Model Content

[0004] In view of the deficiencies in the background technology, the utility model provides a shock absorbing device for a motorcycle.

[0005] The technical scheme adopted by the utility model is: a motorcycle shock absorbing device, including a sleeve, a sliding rod, an outer buffer spring and an inner buffer spring, the top of the sleeve is provided with an upper limit ring, the bottom of the sliding rod is provided with a lower limit ring, the sliding rod is slidably arranged in the sliding hole of the sleeve, and also includes a collar and an elastic rubber ring, the elastic rubber ring is fixedly sleeved on the sleeve below the upper limit ring, the collar is slidably sleeved on the sleeve below the elastic rubber ring, and the collar is provided with an engaging groove for embedding the elastic rubber ring, the outer buffer spring is sleeved outside the sleeve and the sliding rod, and one end of the buffer spring is connected to the lower limit ring, and the other end is connected to the collar.

[0006] Furthermore, the elastic rubber ring is provided with a magnetic rubber layer which is magnetically attracted to the sleeve ring.

[0007] Furthermore, the upper limit ring is provided with a mounting seat, and the mounting seat is provided with a mounting hole.

[0008] Furthermore, a spring seat is provided at the top of the sliding hole, one end of the internal buffer spring is connected to the spring seat, and the other end is connected to the top of the sliding rod.

[0009] Furthermore, an upper step ring is provided at the top of the slide rod, and a lower step ring is provided at the opening of the slide hole. The upper step ring and the lower step ring limit each other to prevent the slide rod from sliding out of the slide hole.

[0010] Furthermore, a piston ring is welded to the outer ring of the upper step ring, and a plurality of ventilation grooves are evenly distributed on the outer ring of the piston ring.

[0011] The beneficial effect of the utility model is that the application forms a double buffer mechanism between the elastic rubber ring and the outer buffer spring by arranging an elastic rubber ring and a sleeve ring below the upper limit ring. The elastic rubber ring can initially absorb and disperse the impact force, while the outer buffer spring further alleviates the remaining vibration, thereby significantly improving the overall shock absorption effect and ensuring the comfort and safety of the driver under complex road conditions.

[0012] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

An upper limit ring 5 is provided on the top of the sleeve, a lower limit ring 6 is provided on the bottom of the slide bar, and the slide bar is slidably arranged in a sliding hole 7 of the sleeve. The device also includes a collar 8 and an elastic rubber ring 9. The elastic rubber ring is fixedly sleeved on the sleeve below the upper limit ring, the collar is slidably sleeved on the sleeve below the elastic rubber ring, and the collar is provided with an engaging groove 10 for embedding the elastic rubber ring. The outer buffer spring is sleeved outside the sleeve and the slide bar, and one end of the buffer spring is connected to the lower limit ring, and the other end is connected to the collar.

[0022] In the above technical solution, by arranging an elastic rubber ring and a collar below the upper limit ring, a double buffer mechanism is formed between the elastic rubber ring and the outer buffer spring. The elastic rubber ring can initially absorb and disperse the impact force, while the outer buffer spring further alleviates the remaining vibration, thereby significantly improving the overall shock absorption effect and ensuring the comfort and safety of the driver under complex road conditions.
