[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0020] As Figures 1 to 6 shown, this embodiment provides a multi-axis steering chassis toe adjustment tooling, including a positioning disc 1, a positioning rod 4, and a wire reel with a plumb bob 5. The positioning disc 1 is installed on the hub bolts of each steering wheel of the chassis and fastened with nuts. The positioning rod 4 is assembled on the positioning disc 1, and the wire reel with a plumb bob 5 is hung at the same position on the outer positioning rod 4 of the first axle 100 and the last axle 200.

[0021] In this embodiment, the positioning disc 1 includes an arc-shaped plate 11 and flat plates 12 on both sides. The arc-shaped plate 11 is provided with mounting holes 13 and is installed on the hub bolts of each steering wheel of the chassis through the mounting holes 13. The flat plates 12 on both sides are symmetrically provided with positioning rod assembly holes 14.

[0022] In this embodiment, the two positioning rods 4 on all the positioning discs 1 are in a horizontal state.

[0023] In this embodiment, the positioning rod 4 is assembled on the positioning disc 1 through a positioning nut 2 and a washer 3.

[0024] In this embodiment, the positioning rod 4 is provided with scale lines.

[0025] In this embodiment, the wire reel with a plumb bob 5 is hung at the same scale line on the outer positioning rod 4 of the first axle and the last axle.

[0026] In this embodiment, the wire reel with plumb bob 5 includes a wire reel 51 and a plumb bob 52. The wire reel 51 is hung on the positioning rod 4, and the plumb bob 52 is installed at the end of the wire reel 51.

[0027] The working principle of the above structure:

[0028] First, install the front alignment adjustment tooling positioning plate 1 on the hub bolts of each steering wheel of the chassis and fasten it with nuts. Then, assemble the positioning rod 4 on the positioning plate 1 with the positioning nut 2 and washer 3, so that the two positioning rods 4 on all the positioning plates 1 are in a horizontal state. Hang the wire reel with plumb bob 5 on the same scale line of the outer positioning rods 4 on the first axle 100 and the last axle 200. By adjusting the chassis steering system device, make the difference between the readings of the plumb lines of the wire reel with plumb bob 5 on the left and right sides of the same axle equal to the difference between the readings of the two positioning rods 4. Multiply the difference in readings by 2 to obtain the front alignment value of the steering system axle.

[0029] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
