[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The mining vehicle in this embodiment uses an independent suspension, such as Figure 1-Figure 2 As shown, it includes a slewing bearing 1, an upper suspension 4, a lower suspension 5, a guide column 6 and an oil-gas spring 7; the fixed end of the slewing bearing 1 is fixed to the vehicle, the rotating end of the slewing bearing 1 is connected to the upper suspension 4, the lower suspension 5 is connected to the tire 9 of the vehicle, the upper suspension 4 is slidably connected to the lower suspension 5 through the guide column 6, and an oil-gas spring 7 is also connected between the upper suspension 4 and the lower suspension 5, and the two ends of the oil-gas spring 7 are respectively hinged to the upper suspension 4 and the lower suspension 5.

[0024] In this embodiment, the rotating end of the slewing bearing 1 is connected to a guide sleeve 2, which is internally connected to a guide rod 3. The bottom end of the guide sleeve 2 is connected to the top of the upper suspension 4. During movement, the guide rod 3 drives the guide sleeve 2, which in turn drives the suspension assembly to rotate.

[0025] In this specific embodiment, the guide connecting rod 3 is connected to the guide connecting sleeve 2 through bolts, and the guide connecting sleeve 2 is connected to the upper suspension 4 through bolts.

[0026] In this specific embodiment, the fixed end of the slewing bearing 1 is connected to the vehicle via bolts.

[0027] In this embodiment, two guide posts 6 are symmetrically provided on both sides of the upper suspension 4, and two guide sleeves 8 are symmetrically provided on both sides of the lower suspension 5. The two guide posts 6 are slidably connected to the two guide sleeves 8. The arrangement of the guide posts 6 and the guide sleeves 8 enables the lower suspension 5 to slide on the guide posts 6, thereby realizing the separate structure and movement relationship of the upper and lower suspensions 5.
