Embodiment 1
[0026] Embodiment one, see figure 1 , a side impact energy-absorbing automobile bridge assembly, including a vehicle frame 1, an axle housing 2, a front axle 3 and two side impact protection mechanisms 4.
[0027] Vehicle frame 1 is connected on axle housing 2 and front axle 3 by suspension mechanism.
[0028] The axle housing 2 is provided with a reducer installation section 21 and two axle shaft installation sections 22 located on both sides of the reducer installation section. The free end of the axle shaft mounting section 22 is provided with a wheel joint 23 . The wheel joint 23 is connected with the rear wheel 11 .
[0029] The front axle 3 includes a cross bar 31 and two suspension arms 32 located at both ends of the cross bar. The suspension arm 32 is connected to the front wheel 12 .
[0030] Two side impact protection mechanisms 4 are distributed on the left and right sides of the vehicle frame 1 . The side impact protection mechanism 4 includes a side protectio...
Embodiment 2
[0047] Embodiment two, the difference with embodiment one is:
[0048] see Figure 5 , the inner peripheral surface of the inner circular tube 5161 is provided with a vane 5168 for guiding the rotation of the seal head 516 of the axle housing portion when the fluid flows through the inner circular tube. The half shaft installation section 22 is also provided with a support frame 518 . The supporting frame 518 is rotatably connected with a connecting sleeve 519 through a plane bearing 5181 . The connecting sleeve 519 is connected with an annular blade 5191 . A limiting portion 5192 is formed between the annular blade 5191 and the connecting sleeve 519 . The blade 5191 is provided with an annular cutting edge 5193 . The annular cutting edge 5193 is aligned with the bottom wall 5163 . The outer diameter of the blade 5191 is equal to the inner diameter of the inner circular tube 5161.
[0049] During use, if the seal head 516 of the axle housing is sprayed out, before the an...
