Description

The utility model also relates to a vehicle provided with the above-mentioned cross member assembly for an electric wide-body vehicle. Background Art
[0002] At present, in the field of mining engineering vehicles, electric wide-body vehicles are gradually favored because of their low use cost and less environmental pollution. In an electric wide-body vehicle, the bracket of the motor and the cross member adopt a split design scheme, and the two are independent of each other and are respectively firmly installed on the vehicle frame through a series of bolt connectors. Although this design method meets the basic assembly and function requirements to a certain extent, it also brings structural problems that cannot be ignored.
[0003] Specifically, since the motor bracket and the cross member, as two independent components, both need to occupy the installation space and fastening points on the vehicle frame, the force on a local area of the vehicle frame becomes more complex and concentrated. Excessive bolt connections not only increase the complexity of the assembly process, but also inevitably weaken the original structural strength of the vehicle frame in this connection area, resulting in a decrease in the bearing capacity of the overall vehicle frame when facing bumpy road conditions or collision impacts.
[0004] In addition, the split setting may also cause an increase in the gap between components, thereby affecting the driving smoothness and noise control of the vehicle. Considering the above factors, it is not conducive to improving the overall use quality of the vehicle. Summary of the Utility Model

[0051] This embodiment relates to a crossbeam assembly for an electric wide-body vehicle, aiming to improve the use quality of the electric wide-body vehicle by optimizing the structure of the crossbeam and the installation structure of the motor 4.
[0052] In terms of the overall structure, as Figure 1 shown, the crossbeam assembly in this embodiment includes a beam main body 1, a mounting bracket 2, and a motor mounting part 3.
[0053] Among them, the beam main body 1 is assembled on the vehicle frame 5 through the mounting bracket 2, the motor mounting part 3 is assembled on the mounting bracket 2, and can serve as the mounting base for the motor 4. The motor mounting part 3 includes a connecting part 302 and a bearing part 301. The connecting part 302 is connected to the mounting bracket 2 to constrain the bearing part 301 on the mounting bracket 2. An installation cavity is formed on the bearing part 301, and the motor 4 is assembled in the installation cavity.
[0054] With the above settings, the crossbeam assembly in this embodiment integrates the motor 4 bracket on the mounting bracket 2, reduces the mounting holes required for mounting the motor 4 bracket on the vehicle frame 5, improves the structural strength of the vehicle frame 5, and can provide a mounting base for the motor 4 while ensuring the functions of the crossbeam. The structure is simple, the structural strength of the vehicle frame 5 is improved, and the effect of improving the use quality of the electric wide-body vehicle is achieved.

The support portion 202 includes a support plate 2021 extending from the mounting bracket 2 towards the vehicle frame 5, and a reinforcing plate 2022 provided below the support plate 2021.

Matching mounting holes are provided on the connecting ear 3021 and the mounting bracket 2. Through the setting form of the connecting ear 3021 cooperating with the connecting piece 3022, it is convenient for the assembly of the motor mounting part 3 on the mounting bracket 2. The structure is simple, easy to assemble, and beneficial to the design and implementation.

The second plate body 3012 extends obliquely from the end of the first plate body 3011 towards the bottom of the motor 4, and the fourth plate body 3014 extends obliquely from the end of the third plate body 3013 towards the bottom of the motor 4. One side of the first plate body 3011 and the third plate body 3013 bears the motor 4, and the other side of the second plate body 3012 and the fourth plate body 3014 bears the motor 4. The two sides cooperate with each other to disperse the force, improving the structural stability of the motor 4 after assembly.
[0061] Specifically, the shapes of the first plate body 3011, the second plate body 3012, the third plate body 3013, and the fourth plate body 3014 can be the same or different.
