Embodiment 1
[0028] Embodiment one, see figure 1 , a car front axle with a tubular structure, including a cross bar 5. The cross bar 5 is a circular steel pipe structure. The cross bar 5 is a straight bar structure. Two ends of the cross bar 5 are respectively provided with a vehicle frame supporting portion 1 . The frame supporting part 1 is a supporting block. The vehicle frame supporting part 1 is welded together with the cross bar 5 . Two ends of the cross bar 5 are respectively connected with a cantilever 2 . The cantilever 2 is a forged or cast structure. Cantilever 2 is welded together with cross bar 5. The front and rear surfaces of the cantilever 2 are respectively provided with a turning protection block 21 . The cantilever 2 is provided with a main pin hole 22 . The axis L3 of the kingpin hole is inclined toward the middle of the crossbar 5 . The inclination angle A1 of the kingpin hole axis is 3°~7.5°.

Embodiment 2
[0031] Embodiment two, the difference with embodiment one is:
[0032] see Figure 4, There are two bearings 23 inside the kingpin hole 22 . A first gear 24 and a second gear 25 meshed together are arranged between the two bearings 23 . The first gear 24 is coaxial with the bearing 23 . The second gear 25 is rotatably connected with the cantilever 2 through the short shaft 251 .
[0033] see Figure 5 , the first gear 24 is provided with a refueling mechanism 8 . The number of refueling mechanisms 8 is equal to the number of teeth of the first gear 24 .
[0034] see Figure 6 , The refueling mechanism 8 includes an oil outlet 81 , an air supply port 82 , a sealing head 83 , a first spring 84 , a cylinder 85 and a piston 86 . The oil outlet 81 and the air supply port 82 of the same fueling mechanism are arranged on the tooth top 241 of the same tooth of the first gear 24, and the tooth top of the same tooth is only provided with an oil outlet and an air supply port of th...
Embodiment 3
[0039] Embodiment three, the difference with embodiment two is:
[0040] see Figure 8 , two ends of the cross bar 5 are respectively provided with an installation cavity 55 (only the installation cavity at the left end is shown in the figure). The installation cavity 55 is located between the frame support part 1 and the suspension arm 2 . The upper and lower walls of the installation cavity 55 are provided with shock absorbing structures 3 .
[0041] see Figure 9 The damping structure includes a lock nut 35 , an adjusting nut 34 , a core sleeve 33 , a butterfly spring 32 with a small end facing the core sleeve, and a mounting plate 31 that are sequentially abutted together in the vertical direction. An adjusting screw 36 is fixedly connected to the mounting plate 31 . The adjusting screw rod 36 is screwed together with the adjusting nut 34 and the locking nut 35 after passing through the butterfly spring 32 and the core sleeve 33 . The core sleeve 33 is provided with a...
