Embodiment 1
[0035] Embodiment one, see figure 1 , a front axle of an electric vehicle provided with a steering link, comprising a main girder 1 and a steering link 5. The main beam 1 is a square tubular structure (of course, the circular tube structure is also possible, but the circular tube structure is not as convenient as the square tube structure for installing other components). The main beam 1 extends in the left-right direction of the vehicle. A mounting seat 3 is respectively connected to the left and right ends of the main beam 1 . The mounting base 3 is connected with a claw shaft 4 . Claw shaft 4 is fixedly connected with steering arm 41 . The steering link 5 includes a middle section 51 and two side sections 52 . Both ends of the middle section 51 are provided with screw heads 53 . The thread directions of the thread heads 51 at both ends of the middle section 51 are opposite. One ends of the two side sections 52 are hinged together with the two steering arms 41 in one-t...
Embodiment 2
[0046] Embodiment two, the difference with embodiment one is:
[0047] see image 3 , The main beam 1 is pierced with a circular energy-absorbing inner tube 11 . The inner surface of the main beam 1 is provided with an inner friction layer 12 . The energy-absorbing inner tube 11 includes a left tube body 111 and a right tube body 112 . The outer peripheral surfaces of the left pipe body 111 and the right pipe body 112 are provided with an outer friction layer 113 . The outer friction layer 113 covers the energy-absorbing inner tube 11 along the circumferential direction of the energy-absorbing inner tube 11 . The left end of the left pipe body 111 is connected with the main beam 1 through the left energy-absorbing spring 13 . The right end surface of the left tubular body 111 is provided with a plurality of first reversing teeth 114 distributed along the circumferential direction of the left tubular body. The right end of the right pipe body 112 is connected with the main...
Embodiment 3
[0049] Embodiment three, the difference with embodiment two is:
[0050] see Figure 4 , The left and right ends of the main beam 1 are respectively provided with a spring steel plate mounting plate 2 . The spring steel plate mounting plate 2 is connected with the main beam 1 by welding.
[0051] see Figure 5 , the spring steel plate mounting plate 2 is only supported on the main beam 1 by two suspension mechanisms 9 . Each suspension mechanism 9 is connected with a coating type heat preservation mechanism 8 . The two suspension mechanisms 9 are located on the front and rear sides of the main beam 1, and there are correspondingly two coating-type thermal insulation mechanisms 8 (only one coating-type thermal insulation mechanism 8 can be seen in the figure, and the other is blocked by the main beam 1 to see not see).
[0052] The suspension mechanism 9 includes a connecting rod 91 and five shock absorbing rods 92 . The connecting rod 91 is an arc-shaped structure that a...
