[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 5 A vehicle frame cross member 100 according to an embodiment of the present invention is described. The present invention also provides a vehicle frame, and further provides a vehicle.

[0032] Reference Figure 1-Figure 4 As shown, the frame beam 100 of the embodiment of the utility model includes: a main beam 10 and a suspension bracket 20. The main beam 10 is provided with a mounting portion 11 protruding outward on one side in the front-rear direction of the vehicle, and the cross-sectional area of ​​the mounting portion 11 gradually decreases in the direction away from the main beam 10.

[0033] The frame crossbeam 100 may be the fourth crossbeam of the frame described below. The fourth crossbeam is generally arranged in the middle front part of the frame and together with other crossbeams constitutes the main load-bearing part of the frame. The fourth crossbeam is mainly used to increase the stability and lateral torsion resistance of the frame and provide support when the vehicle is hit from the side. It can also provide a fixing point for the transmission, transfer case, etc. The fourth crossbeam of the frame is crucial to ensure the structural integrity, safety performance and driving stability of the vehicle.

[0034] The suspension bracket 20 is welded to the mounting portion 11, and the suspension bracket 20 is used to fix the transmission suspension. Thus, firstly, the mounting portion 11 is made into a duckbill shape and the cross section in the height direction and the width direction of the vehicle is gradually reduced, which provides a more convenient and strong lap environment for the suspension bracket 20, and can increase the weld bead, thereby improving the connection strength between the suspension bracket 20 and the main cross beam 10.

[0035] The suspension bracket 20 and the mounting portion 11 can be connected by welding. That is, the suspension bracket 20 is welded to the main cross beam 10 to form a whole, which solves the problem of insufficient installation point dynamic stiffness and sheet metal strength caused by the long cantilever of the suspension bracket 20.

[0036] Therefore, by providing a mounting portion 11 protruding outward on one side in the front-rear direction of the vehicle and welding the suspension bracket 20 to the mounting portion 11, this can not only play a role of avoidance, but also improve the connection strength between the suspension bracket 20 and the main beam 10.

[0037] Reference Figure 2 and Figure 4 As shown, the upper surface of the mounting portion 11 is recessed downward to form a mounting groove 12, and the upper wall of the suspension bracket 20 is fixed in the mounting groove 12. That is, the mounting groove 12 is provided on the upper surface of the mounting portion 11, so that the upper wall of the suspension bracket 20 can be installed and matched in the mounting groove 12, thereby increasing the matching area between the suspension bracket 20 and the mounting portion 11, that is, in this way, the connection area between the suspension bracket 20 and the mounting portion 11 can be increased, and then the connection strength between the suspension bracket 20 and the mounting portion 11 can be increased.

[0038] The upper surface of the suspension bracket 20 is lower than the upper surface of the main beam 10. That is, the upper surface of the suspension bracket 20 is set to be lower than the upper surface of the main beam 10, so that the flatness of the upper surface of the main beam 10 can be improved.

[0039] Furthermore, the lower surface of the suspension bracket 20 is flush with the lower surface of the main beam 10 , which can improve the flatness of the lower surface of the suspension bracket 20 .

[0040] Reference Figure 4As shown, a matching inclined surface 13 is provided on one side of the mounting portion 11 facing the suspension bracket 20, and the matching inclined surface 13 is spaced from the inner wall of the suspension bracket 20. That is to say, except for the welding position between the suspension bracket 20 and the mounting portion 11, which is in contact with the mounting portion 11, the rest of the positions make the mounting portion 11 and the suspension bracket 20 form a hollow structure, which is conducive to increasing the cross-section of the suspension bracket 20 that is actually subjected to force, thereby improving the load-bearing range of the suspension bracket 20.

[0041] Furthermore, a groove 14 is provided on the matching inclined surface 13, and a hollow structure is formed between the groove 14 and the upper surface of the suspension bracket 20. Similarly, by providing the groove 14 on the matching inclined surface 13, a hollow structure is formed between the main crossbeam 10 and the suspension bracket 20, and this hollow structure is conducive to increasing the actual force-bearing cross-section of the suspension bracket 20, thereby improving the load-bearing range of the suspension bracket 20. In addition, providing the groove 14 on the matching inclined surface 13 can improve the structural strength of the matching inclined surface 13.

By dividing the suspension bracket 20 into the first upper plate 21 and the first lower plate 22, and openings 23 are provided on the first upper plate 21 and the first lower plate 22, the mounting portion 11 can extend into the opening 23, so that the connection area between the mounting portion 11 and the suspension bracket 20 can be increased, and further the connection strength between the suspension bracket 20 and the mounting portion 11 can be increased.

[0043] Reference Figure 4 and Figure 5 As shown, the suspension bracket 20 further includes: a first reinforcing plate 25, a first cavity 24 is defined between the first upper plate 21 and the first lower plate 22, and the first reinforcing plate 25 is disposed in the first cavity 24 and fixedly connected to the first upper plate 21. That is, since the contact surface between the suspension bracket 20 and the transmission suspension is small, in order to enhance the sheet metal strength of the first upper plate 21, the first reinforcing plate 25 is welded on the first upper plate 21 to partially reinforce the first upper plate 21, that is, the structural strength of the first upper plate 21 can be improved by providing the first reinforcing plate 25.

[0044] Furthermore, the transmission suspension may also be fixedly connected to the first reinforcing plate 25 , so that the connection strength between the transmission and the suspension bracket 20 can be improved.

[0046] Furthermore, there may be a plurality of the first mounting hole 26 and the second mounting hole 27 , which can improve the fixing strength of the transmission and the suspension bracket 20 .

[0047] The transmission is fixedly connected to the first upper plate 21 and the first reinforcing plate 25 via fasteners, so that the connection strength between the transmission and the suspension bracket 20 can be improved.

[0048] Furthermore, a third avoidance groove 28 is provided on the first lower plate 22, and the third avoidance groove 28 is connected to the first cavity 24. The third avoidance groove 28 and the first reinforcing plate 25 are arranged opposite to each other, so that the third avoidance groove 28 can facilitate the fixed connection between the transmission suspension and the suspension bracket 20.

The second reinforcing plate 17 is disposed in the second cavity and is fixedly connected to the second upper plate 15. In other words, the main cross beam 10 is composed of the second upper plate 15 and the second lower plate 16 that are interlocked, so that the stability and lateral torsion resistance of the frame can be increased by the second upper plate 15 and the second lower plate 16, and support can be provided when the vehicle is hit from the side.

[0051] Furthermore, a second reinforcing plate 17 is disposed in a second cavity defined between the second upper plate 15 and the second lower plate 16 , and the structural strength of the main cross beam 10 can be improved by the second reinforcing plate 17 .
