[0020] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 4As shown, this embodiment provides an intelligently adjustable motorcycle shock absorber, including a spring system 1, a damping system 2, a nitrogen tank system 3 and a thermal control system 4, the spring system 1 includes a spring upper seat device 11, a spring body 12 and a spring lower seat device 13 installed in sequence, the spring body 12 is deformed between the spring upper seat device 11 and the spring lower seat device 13 to absorb vibration energy, the damping system 2 includes a damping tube 21, a damping rod 22 and an upper mounting seat 23, the upper mounting seat 23 is installed at the upper end of the damping tube 21, the damping rod 22 is slidably installed in the damping tube 21, the lower end of the damping rod 22 is installed on the spring lower seat device 13, the damping tube 21 is divided into an upper chamber 211 and a lower chamber 212 by the damping rod 22, and a damping flow channel 221 connecting the upper chamber 211 and the lower chamber 212 is opened on the damping rod 22, and the damping rod 22 slides in the damping tube 21 following the movement of the spring lower seat device 13, thereby making the shock absorber The oil flows in the damping flow channel 221 to produce a damping effect. The thermal control system 4 is installed on the upper mounting seat 23, and the nitrogen tank system 3 is installed on the thermal control system 4. The nitrogen tank system 3 is divided into an oil chamber 311 and an air chamber 312. The air chamber 312 is used to push the shock-absorbing oil back to the upper chamber 211. The thermal control system 4 is connected to the oil chamber 311 and the upper chamber 211 respectively. The thermal control system 4 includes a thermal control mounting block 41, a thermal control airbag 42 and a thermal control piston 43. The thermal control mounting block 41 is provided with a thermal control channel 411. The thermal control airbag 42 is installed on the thermal control mounting block 41. The thermal control piston 43 is slidably installed on the thermal control mounting block 41. The thermal control piston 43 points to the thermal control channel 411. The thermal control piston 43 is transmission-connected with the thermal control airbag 42. After the shock-absorbing oil becomes hot, the thermal control airbag 42 expands and then pushes the thermal control piston 43 to reduce the diameter of the thermal control channel 411, thereby increasing the damping after the viscosity of the shock-absorbing oil is reduced.
[0021] Specifically, the spring upper seat device 11 is installed on the damping tube 21 through a threaded pair, so that the preload of the spring body 12 can be adjusted. The specific adjustment method is that when the spring upper seat device 11 is adjusted in a direction away from the upper mounting seat 23, the preload of the spring body 12 increases, thereby increasing the preload of the entire motorcycle shock absorber. On the contrary, when the spring upper seat device 11 is adjusted in a direction close to the upper mounting seat 23, the preload of the spring body 12 decreases, thereby reducing the preload of the entire motorcycle shock absorber.
[0022] Specifically, the nitrogen tank system 3 includes a nitrogen tank body 31 and a nitrogen tank piston 32. The nitrogen tank piston 32 is slidably installed in the nitrogen tank body 31. The nitrogen tank piston 32 divides the nitrogen tank body 31 into an oil chamber 311 and an air chamber 312. The nitrogen tank body 31 is provided with a gas filling hole at the bottom of the air chamber 312. The gas filling hole can also adjust the preload by adjusting the air pressure in the air chamber 312. The gas in the air chamber 312 pushes the nitrogen tank piston 32 to slide upward and then pushes the damping oil into the upper chamber 211. When the air chamber 312 is pressurized through the gas filling hole, the preload of the entire motorcycle shock absorber increases. When the air is exhausted from the air chamber 312 through the gas filling hole, the preload of the entire motorcycle shock absorber decreases.
[0023] Specifically, an oil seal and a dust cover are sequentially arranged at the bottom of the damping tube 21 from the inside to the outside, thereby preventing the shock absorbing oil from leaking.
[0024] Specifically, a main piston 222 is installed on the damping rod 22, and both ends of the damping channel 221 are respectively connected to the upper and lower ends of the main piston 222 of the damping rod 22. The damping channel 221 increases the flow resistance of the shock absorbing oil and consumes the elastic potential energy.
[0025] Specifically, both ends of the thermal control mounting block 41 are respectively mounted on the upper mounting seat 23 and the nitrogen tank system 3 through threaded pairs, so as to facilitate the fixation of the thermal control mounting block 41 .
[0026] Specifically, an airbag mounting cavity is provided on the thermal control mounting block 41, and the thermal control airbag 42 is installed in the airbag mounting cavity. The width of the airbag mounting cavity is greater than the thermal control airbag 42, thereby providing a stroke for the movement of the thermal control piston 43. It is worth noting that in order to facilitate the installation of the thermal control airbag 42, a mounting cavity forming block 45 is installed on the thermal control mounting block 41 through a threaded pair, and an airbag mounting cavity is formed between the thermal control mounting block 41 and the mounting cavity forming block 45.
[0027] Specifically, the thermal control airbag 42 is hollow in design, and a temperature sensing channel 412 is also provided on the thermal control mounting block 41. The temperature sensing channel 412 is respectively connected to the oil chamber 311 and the upper chamber 211, and the temperature sensing channel 412 extends into the middle of the thermal control airbag 42. The shock absorber oil flowing in the temperature sensing channel 412 is transmitted to the thermal control airbag 42, so that the thermal control airbag 42 pushes the thermal control piston 43 to slide according to the temperature change, and quickly responds to the temperature change of the shock absorber oil. In order to facilitate the docking of the thermal control airbag 42 and the temperature sensing channel 412, conical coupling rings 421 adapted to the corresponding temperature sensing channel 412 are provided at both ends of the thermal control airbag 42. When the thermal control airbag 42 is installed, the conical coupling rings 421 at both ends of the thermal control airbag 42 are embedded in the corresponding temperature sensing channel 412, indicating that it is installed in place.
[0028] Specifically, when the temperature of the shock absorber oil passing through the temperature sensing channel 412 increases, the thermal control airbag 42 expands and then pushes the thermal control piston 43 to reduce the diameter of the thermal control channel 411, thereby adaptively increasing the damping when the shock absorber oil temperature increases, so as to achieve the effect of adaptively controlling the shock absorber damping of the motorcycle shock absorber.
