[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] Reference below Figure 1-Figure 3 The vehicle bridge 100 according to an embodiment of the present invention is described, and the vehicle bridge 100 is applied to a vehicle, for example, a vehicle with a large wheelbase.

[0030] like Figure 1 and Figure 2 As shown, the bridge 100 according to the present invention includes: an upper beam body 10, a lower beam body 20 and a middle beam body 30, the upper beam body 10 is provided with at least one leaf spring mounting seat 11, the lower beam body 20 is spaced below the upper beam body 10, the middle beam body 30 is vertically arranged between the upper beam body 10 and the lower beam body 20, and a reinforcing rib 40 is provided on at least one side of the middle beam body 30, and the reinforcing rib 40 is correspondingly located below the leaf spring mounting seat 11; wherein, the thickness of the middle beam body 30 is a, and a satisfies the relationship: 12mm≤a≤20mm.

[0031] It can be understood that the upper beam 10, the lower beam 20 and the middle beam 30 constitute the main structure of the vehicle bridge 100. The upper beam 10 and the lower beam 20 are spaced apart in the up and down directions. The upper end of the middle beam 30 is connected to the upper beam 10, and the lower end of the middle beam 30 is connected to the lower beam 20. This arrangement can make the middle beam 30 vertically connected between the upper beam 10 and the lower beam 20, so that the cross-section of the upper beam 10, the lower beam 20 and the middle beam 30 can form an "I" shape, thereby ensuring the structural performance of the vehicle bridge 100.

[0032] The upper beam 10 is provided with two leaf spring mounting seats 11, which are arranged transversely and spaced apart, facilitating the installation of the leaf springs on the axle bridge 100 via the leaf spring mounting seats 11. A reinforcing rib 40 is provided on at least one side of the center beam 30. This reduces the thickness of the center beam 30 while ensuring the overall structural strength and rigidity of the axle bridge 100. This optimizes the structure of the axle bridge 100 and reduces its weight, thereby achieving a lightweight design and ensuring vehicle safety. For example, the weight of the axle bridge 100 can be reduced by approximately 5.3 kg, and the cost can be reduced by approximately 68.9 yuan.

[0033] Optionally, the thickness of the center beam 30 should be moderate. If it is less than 12 mm, the reinforcing effect of the ribs 40 will be insufficient, resulting in insufficient strength and rigidity of the center beam 30, thereby affecting the overall structural strength and rigidity of the bridge 100 and, in turn, the safety performance of the vehicle. For example, to ensure the overall structural strength and rigidity of the bridge 100, a is 12 mm, 13 mm, or 14 mm. An appropriate parameter should be considered during the specific design.

[0034] The thickness of the center beam 30 should not be too large. If it exceeds 20 mm, this will increase the weight of the center beam 30 and the overall weight of the bridge 100, preventing the lightweight design of the bridge 100 and further affecting the vehicle's power consumption. For example, to achieve a lightweight design of the bridge 100, a is 20 mm, 19 mm, or 18 mm. An appropriate parameter should be considered during the specific design.

[0035] The thickness of the center beam 30 must be within a reasonable range. If the center beam 30 is too thin, the strength and rigidity of the center beam 30 will be insufficient. If the center beam 30 is too thick, the overall weight of the bridge 100 will increase. A reasonable thickness of the center beam 30 ensures the overall structural strength and rigidity of the bridge 100 and achieves a lightweight design. For example, a is 15 mm, 16 mm, or 17 mm. An appropriate parameter should be considered during the specific design.

[0036] Therefore, by setting a middle beam body 30 between the upper beam body 10 and the lower beam body 20, setting a reinforcing rib 40 on at least one side of the middle beam body 30, and setting the reinforcing rib 40 and the leaf spring mounting seat 11 correspondingly, not only the overall structural strength and rigidity of the vehicle bridge 100 can be improved, but also the thickness of the middle beam body 30 can be reduced, thereby optimizing the structure of the vehicle bridge 100 and reducing the weight of the vehicle bridge 100, thereby realizing a lightweight design of the vehicle bridge 100 and ensuring the safety performance of the vehicle.

[0037] Alternatively, as Figure 2As shown, the thickness of the center beam 30 is a, where a satisfies the relationship: a ≥ 15 mm. The thickness of the center beam 30 cannot be too small. If it is less than 15 mm, the reinforcing effect of the ribs 40 will be insufficient, resulting in insufficient strength and rigidity of the center beam 30, thereby affecting the overall structural strength and rigidity of the bridge 100 and, in turn, the safety performance of the vehicle. For example, to ensure the overall structural strength and rigidity of the bridge 100, a is 15 mm or 16 mm. Selecting an appropriate parameter should be considered during the specific design.

[0038] The thickness of the center beam 30 is a, which satisfies the relationship: a ≤ 18 mm. The thickness of the center beam 30 cannot be too large. If it exceeds 18 mm, this will increase the weight of the center beam 30 and the overall weight of the axle bridge 100, preventing the lightweight design of the axle bridge 100 and further affecting the vehicle's power consumption. For example, to achieve a lightweight design of the axle bridge 100, a is 17 mm or 18 mm. Selecting an appropriate parameter is a consideration during the specific design.

[0039] The thickness of the center beam 30 is a, where a satisfies the relationship: 15 mm ≤ a ≤ 18 mm. The thickness of the center beam 30 must be within a reasonable range. If the thickness of the center beam 30 is too small, the strength and rigidity of the center beam 30 will be insufficient. If the thickness of the center beam 30 is too large, the overall weight of the axle bridge 100 will increase. If the thickness of the center beam 30 is within a reasonable range, the overall structural strength and rigidity of the axle bridge 100 can be maintained, and a lightweight design of the axle bridge 100 can be achieved.

[0040] In addition, if Figure 1 As shown, the reinforcement rib 40 extends in the up-down direction, the upper end of the reinforcement rib 40 is connected to the upper beam body 10 , and the lower end of the reinforcement rib 40 is connected to the lower beam body 20 .

[0041] It is understood that the reinforcing ribs 40 are arranged parallel to the center beam 30, that is, the reinforcing ribs 40 extend in the vertical direction, with the upper ends of the reinforcing ribs 40 connected to the upper beam 10 and the lower ends of the reinforcing ribs 40 connected to the lower beam 20. This arrangement allows the reinforcing ribs 40 to be connected to the upper beam 10, the lower beam 20, and the center beam 30. This not only improves the overall structural strength and rigidity of the vehicle bridge 100, but also reduces the thickness of the center beam 30, thereby optimizing the structure of the vehicle bridge 100 and reducing the weight of the vehicle bridge 100, thereby achieving a lightweight design of the vehicle bridge 100 and ensuring the safety performance of the vehicle. For example, the upper beam 10, the lower beam 20, the center beam 30, and the reinforcing ribs 40 are integrally formed, thereby improving the overall structural strength and rigidity of the vehicle bridge 100.

[0042] In particular, if Figure 1As shown, in the left-right direction, the middle portion of the leaf spring mounting seat 11 corresponds to the reinforcing rib 40 in a vertically aligned manner, and the center beam 30 and the reinforcing rib 40 are integrally formed. In other words, the reinforcing rib 40 is disposed below the leaf spring mounting seat 11. This arrangement enhances the structural strength between the leaf spring mounting seat 11 and the upper beam 10, while also reducing the thickness of the center beam 30. This ensures the overall structural strength and rigidity of the vehicle bridge 100, optimizes the structure of the vehicle bridge 100, and further reduces the weight of the vehicle bridge 100, achieving a lightweight design for the vehicle bridge 100. The center beam 30 and the reinforcing rib 40 are integrally formed, facilitating their manufacture and ensuring the overall structural strength and rigidity of the vehicle bridge 100. Of course, the present invention is not limited to this embodiment; the center beam 30 and the reinforcing rib 40 may also be welded together, which also ensures the overall structural strength and rigidity of the vehicle bridge 100.

[0043] In addition, if Figure 2 As shown, a mounting groove 50 is formed between the upper beam 10, the lower beam 20, and the center beam 30, and the center beam 30 forms the bottom of the mounting groove 50. It is understandable that the width of the upper beam 10 is greater than the width of the lower beam 20, and the thickness of the center beam 30 is less than the width of the lower beam 20. In this way, the mounting groove 50 is formed between the upper beam 10, the lower beam 20, and the center beam 30, that is, the center beam 30 serves as the bottom of the mounting groove 50, and the upper beam 10 and the lower beam 20 serve as the edges of the mounting groove 50. This arrangement can form the cross-section of the upper beam 10, the lower beam 20, and the center beam 30 into an "I" shape, thereby ensuring the structural performance of the vehicle bridge 100 and achieving a lightweight design of the vehicle bridge 100.

[0044] In addition, if Figure 3 As shown, the lower beam 20 is provided with a clearance portion 21 for clearing the tie-rod arm 200. Specifically, the clearance portion 21 is provided on one side of the lower beam 20. The tie-rod arm 200 is positioned at one end of the vehicle bridge 100. When the vehicle turns, the tie-rod arm 200 rotates relative to the vehicle bridge 100, and the clearance portion 21 allows the tie-rod arm 200 to clear the vehicle. This arrangement increases the limit of the tie-rod arm 200's movement, thereby increasing the vehicle's steering angle and reducing the vehicle's turning radius, thereby improving vehicle performance. For example, the vehicle's turning radius can be reduced by 3 meters, thereby improving the vehicle's passability.

[0045] Among them, such as Figure 3As shown, the avoidance portion 21 is constructed as an arcuate avoidance groove that is recessed from one side to the other side in the front-to-rear direction of the lower beam body 20. It is understood that the avoidance portion 21 is an arcuate avoidance groove, with the arcuate section near the middle of the lower beam body 20 and the parallel section near the edge of the lower beam body 20. When the vehicle turns, the tie rod arm 200 rotates relative to the bridge 100, and the avoidance portion 21 can avoid the tie rod arm 200. This configuration can increase the extreme position of the tie rod arm 200's movement, thereby increasing the vehicle's steering angle and reducing the vehicle's turning radius, thereby improving vehicle performance.

[0046] In addition, Figure 1 As shown, the lower beam body 20 includes: a middle beam section 22 and a side beam section 23. The side beam sections 23 are respectively connected to the left and right sides of the middle beam section 22. The side beam sections 23 are inclined upward relative to the middle beam section 22. Among them, the avoidance portion 21 is set on the side beam section 23.

[0047] That is to say, the center beam section 22 and the side beam section 23 constitute the main structure of the lower beam body 20, and the side beam section 23 is connected to the left and right ends of the center beam section 22. The center beam section 22 is horizontally arranged, and the side beam section 23 is inclined relative to the center beam section 22. Moreover, the end of the side beam section 23 away from the center beam section 22 is higher than the end close to the center beam section 22. The end of the side beam section 23 away from the center beam section 22 is connected to the transverse tie rod arm 200. This arrangement facilitates the rotation of the transverse tie rod arm 200 relative to the vehicle bridge 100, thereby increasing the steering angle of the vehicle and reducing the turning radius of the vehicle, thereby improving the performance of the vehicle.

[0048] The vehicle axle according to the present invention includes the vehicle axle bridge 100 of the above embodiment. By disposing a center beam 30 between an upper beam 10 and a lower beam 20, and providing reinforcing ribs 40 on at least one side of the center beam 30, and correspondingly disposing the reinforcing ribs 40 and the leaf spring mounting seats 11, the overall structural strength and rigidity of the vehicle axle bridge 100 can be improved, while the thickness of the center beam 30 can also be reduced, thereby optimizing the structure of the vehicle axle bridge 100 and reducing its weight, thereby achieving a lightweight design of the vehicle axle bridge 100 and ensuring vehicle safety performance.

[0049] The vehicle according to the present invention includes the axle of the above embodiment. Such a configuration can achieve a lightweight design of the axle bridge 100, increase the steering angle of the vehicle and reduce the turning radius of the vehicle, thereby improving the performance of the vehicle.
