Embodiment 1

[0036] Embodiment one, see figure 1 , a front axle assembly of an electric vehicle, comprising a main girder 1 and a steering link 5 .

[0037] 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. 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. A spring steel mounting plate reinforcing plate 21 is also provided between the spring steel plate mounting plate 2 and the main beam 1 .

[0038] A mounting seat 3 is respectively connected to the left and right ends of the main beam 1 . The mounting base 3 includes a top wall 31 , a vertical wall 32 and a bottom wall 33 . The upper end of the vertica...

Embodiment 2

[0053] Embodiment two, the difference with embodiment one is:

[0054] 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

[0056] Embodiment three, see Figure 4 , the difference with the second embodiment is:

[0057] The spring steel 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).

[0058] The suspension structure 9 includes a connecting rod 91 and five shock absorbing rods 92 . The connecting rod 91 is an arc-shaped structure that arches downward (certainly upward is also possible). The five damping rods 92 are a horizontal damping rod 921 , two longitudinal damping rods 922 and two vertical damping rods 923 . One end of the connecting rod 91 is connect...

Abstract

The invention relates to an electromobile. An electromobile front axle assembly comprises a main beam, two ends of the main beam are each provided with a claw shaft, the claw shafts are connected with wheel hubs and steering arms, the steering arms arranged on the two ends of the main beam are connected through a steering linkage, the two ends of the main beam are provided with a steel spring plate mounting plate and a mounting seat, the mounting seat comprises a top wall, a vertical wall and a bottom wall, the upper end of the vertical wall is connected to one end, close to the main beam, of the top wall, the lower end of the vertical wall is connected to one end, close to the main beam, of the bottom wall, a U-shaped groove is enclosed by the top wall, the vertical wall and the bottom wall, the claw shaft is connected into the U-shaped groove, and the middle portion of the main beam is provided with a steering machine mounting support. The electromobile front axle assembly and a machining method thereof are provided, wherein the installation of the steel spring plate is convenient, and the joint of the claw shaft and the main beam is not prone deforming, and the problems that in an existing front axle the installation of the steel spring plate is inconvenient, and the joint of the claw shaft and the main beam is prone deforming are solved.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an electric vehicle front axle assembly and a processing method. Background technique [0002] The electric vehicle front axle is a component used to connect a pair of front wheels and support the front end of the frame. A kind of electric vehicle front axle is disclosed in the Chinese patent No. 2011201458076, the authorized announcement date is November 2, 2011, and the patent document titled "Installation structure of electric vehicle front axle for fireworks factory". The front axle of the electric vehicle includes a main beam and a claw shaft, and the claw shaft is rotatably connected to two ends of the main shaft. The existing electric vehicle front axle has the following disadvantages: the main girder is heavy, and it is easy to twist and deform when it is hit by a collision; the joint between the horn shaft and the main girder is easily deformed, resulting in changes in the inclina...
