[0055] In other embodiments, at least another two steering mounting members 122 may be respectively disposed in corresponding steering mounting boxes 13 , etc., which is not limited herein.

[0056] Specifically, the steering gear 12 includes four steering mounting members 122. Two steering mounting members 122 are symmetrically arranged at one end of the steering gear body 121 in the axial direction, which can improve the stability and connection strength of one end of the steering gear body 121 installed on the first longitudinal beam 111. The other two steering mounting members 122 are symmetrically arranged at the other side of the steering gear body 121 in the axial direction, which can improve the stability and connection strength of the other end of the steering gear body 121 installed on the second longitudinal beam 112. The above-mentioned axial direction can be, but is not limited to, the axial centerline direction of the steering gear 12.

[0057] Further, when the steering mounting bracket 1221 includes the above-mentioned first steering bracket 12211, the second steering bracket 12212 and the third steering bracket 12213, the two first steering brackets 12211, the two second steering brackets 12212 and the two third steering brackets 12213 are all symmetrically arranged in the axial direction of the steering gear body 121.

[0058] Furthermore, when the two third steering brackets 12213 are tilted relative to the steering gear body 121, and the two third steering brackets 12213 are symmetrically arranged in the axial direction of the steering gear body 121, the two second steering brackets 12212 are arranged in an eight-shaped shape. When the two first steering brackets 12211 are tilted relative to the steering gear body 121, and the two first reversing brackets are symmetrically arranged in the axial direction of the steering gear body 121, the two first steering brackets 12211 are arranged in an eight-shaped shape.

[0059] When the two third steering brackets 12213 are symmetrically arranged in the axial direction of the steering gear body 121, the mounting groove 131, the first guide groove 1311 and / or the second guide groove 1312 are inclined; or, the first guide groove 1311 and / or the second guide groove 1312 are inclined.

[0060] When the second steering bracket 12212 and the third steering bracket 12213 are arranged vertically, an avoidance groove 12214 is formed between the second steering bracket 12212 and the third steering bracket 12213. The avoidance groove 12214 can avoid at least a part of the first longitudinal beam 111 and / or the second longitudinal beam 112. The specific process of installing the steering gear 12 on the sub-frame structure 11 is as follows. First, at least one steering mounting component 122 in the steering gear body 121 is embedded to the left in a steering mounting box 13, and the avoidance groove 12214 allows the steering mounting component 122 to be more embedded in the first longitudinal beam 111. Secondly, at least another steering mounting component 122 in the steering gear body 121 is embedded in another steering mounting box 13. Then, the steering gear body 121 moves a certain distance to the right, so that the steering mounting hole 12221 in the steering mounting member 122, the guide mounting hole 132 in the steering mounting box 13 and the first longitudinal beam hole 1112 of the first longitudinal beam 111 correspond to each other; and the steering mounting hole 12221 in the steering mounting member 122, the guide mounting hole 132 in the steering mounting box 13 and the second longitudinal beam hole 1122 of the second longitudinal beam 112 correspond to each other.
