[0033] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0034] The front axle beam 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 3 As shown, the front axle beam 1 according to the embodiment of the present utility model includes a middle section 100 , a first kingpin mounting section 200 and a second kingpin mounting section 300 .

[0036] The middle section 100 spans between the left longitudinal beam and the right longitudinal beam. The first kingpin mounting section 200 is mounted on one end of the middle section 100, the first kingpin mounting section 200 extends in a direction away from the middle section 100, and a first kingpin mounting hole 201 is configured at the end of the first kingpin mounting section 200. The second kingpin mounting section 300 is mounted on the other end of the middle section 100, the second kingpin mounting section 300 extends in a direction away from the middle section 100, and a second kingpin mounting hole 301 is configured at the end of the second kingpin mounting section 300.

[0037] According to the front axle beam 1 of the embodiment of the utility model, the first kingpin mounting section 200 and the second kingpin mounting section 300 are respectively mounted at the two ends of the middle section 100, and the first kingpin mounting section 200 and the second kingpin mounting section 300 are both configured with a first kingpin mounting hole 201 and a second kingpin mounting hole 301, and the kingpin can be connected to the front axle beam 1 through the first kingpin mounting hole 201 and the second kingpin mounting hole 301. The first kingpin mounting section 200 and the second kingpin mounting section 300 at the two ends can be selected with different lengths according to different vehicle models, so as to adapt to different kingpin center distances, thereby improving the versatility of the front axle beam 1.

[0038] In addition, the front axle beam 1 structure adopts a segmented structural design of the middle section 100, the first kingpin mounting section 200 and the second kingpin mounting section 300. The middle section 100, the first kingpin mounting section 200 and the second kingpin mounting section 300 can be separately molded and manufactured in segments, which reduces the mold volume and molding difficulty, and also has a replaceable function, which is convenient for maintenance and replacement. Through segmented molding production, manufacturing costs are also reduced and product quality is improved.

[0039] Therefore, the front axle beam 1 according to the embodiment of the utility model has the advantages of high versatility, low molding difficulty, and low cost.

[0040] In some specific embodiments of the present invention, Figure 1 As shown, the first kingpin mounting section 200 and the second kingpin mounting section 300 are symmetrically mounted at both ends of the middle section 100. Through symmetrical mounting, the first kingpin mounting section 200 and the second kingpin mounting section 300 are evenly distributed at both ends of the middle section 100, which can effectively balance the bearing capacity, avoid the situation of local overload, improve the overall force balance, and improve the stability and reliability of the front axle beam 1 structure. In addition, due to the structure of the first kingpin mounting section 200 and the second kingpin mounting section 300 being formed separately, the complexity of the mold is relatively low, which reduces the mold manufacturing cost, reduces the production investment, and improves the economic efficiency of production.

[0041] In some specific embodiments of the present invention, Figure 2 As shown, the middle section 100 is constructed as an I-beam. The I-beam can provide good bending rigidity, can effectively resist the bending force applied from the outside, and ensure the structural strength of the front axle beam 1. At the same time, the I-beam structure can effectively share the force, so that the lateral force, longitudinal force and torque are evenly transmitted to various parts of the middle section 100, thereby improving the bearing capacity of the overall structure of the front axle beam 1.

[0042] In some specific embodiments of the present invention, Figure 1As shown, one side of the first kingpin mounting section 200 adjacent to the middle section 100 is configured as a first I-beam connecting section 210 matching the cross-sectional shape of one end of the middle section 100, and one side of the second kingpin mounting section 300 adjacent to the middle section 100 is configured as a second I-beam connecting section 310 matching the cross-sectional shape of the other end of the middle section 100.

[0043] The cross-sections of the first I-beam connecting section 210 and the second I-beam connecting section 310 form an I-beam structure with a shape matching the middle section 100, and the structural integrity is stronger. The first I-beam connecting section 210 and the second I-beam connecting section 310 connect the first kingpin mounting section 200 and the second kingpin mounting section 300 with the middle section 100, so that the entire front axle beam 1 structure forms a complete whole, and the stability and strength of the structure are enhanced. Moreover, the first I-beam connecting section 210 and the second I-beam connecting section 310 are both I-beam structures, which have good torsion resistance and can better withstand the force and torque at the connection, ensuring that the front axle beam 1 can work normally without being excessively damaged and deformed. At the same time, the I-beam structure can increase the structural strength and stability of the first I-beam connecting section 210 and the second I-beam connecting section 310, thereby improving the bearing capacity and safety of the front axle beam 1.

[0044] In some specific embodiments of the present invention, Figure 1 As shown, the middle section 100 is constructed with an upper wing plate portion 110, a lower wing plate portion 120 and a connecting portion 130 connecting the upper wing plate portion 110 and the lower wing plate portion 120. Leaf spring mounting platforms 111 are constructed on both sides of the upper wing plate portion 110. The leaf spring mounting platforms 111 are constructed with leaf spring mounting holes 101, and the lower wing plate portion 120 is constructed with a width reduction at the bottom of the leaf spring mounting holes 101. The leaf spring mounting holes 101 are evenly arranged around the leaf spring mounting platforms 111. The leaf springs are firmly mounted on the leaf spring mounting platforms 111 by fasteners to ensure their correct position and fixity, thereby achieving the support function for the suspension system. In addition, the leaf spring mounting platforms 111 are respectively located on the symmetrical sides of the upper wing plate portion 110, which can evenly share the force on the upper wing plate portion 110, help balance the force, reduce structural fatigue and damage of the middle section 100, and extend the service life.

[0045] In addition, the width of the lower wing plate portion 120 gradually decreases at the bottom of the leaf spring mounting platform 111, which can avoid U-bolts for installing leaf springs, and can reduce the amount of material used without affecting the structural strength, reduce the weight of the front axle beam 1 itself, and help reduce the load on the entire structure.

[0046] In some specific embodiments of the present invention, Figure 1 and Figure 3As shown, both ends of the middle section 100, the first kingpin mounting section 200 and the second kingpin mounting section 300 are constructed with flange plates 10. The flange plate 10 of the first kingpin mounting section 200 is installed through a fastener 11 and the flange plate 10 at one end of the middle section 100, and the flange plate 10 of the second kingpin mounting section 300 is installed through a fastener 11 and the flange plate 10 at the other end of the middle section 200.

[0047] By arranging flange plates 10 at different parts of the front axle beam and connecting them with fasteners 11, it is possible to ensure that the connection between the components is tight and stable, avoid loosening or falling off during driving, and improve the stability and safety of the overall structure. Moreover, the flange plate 10 connected to the front axle beam 1 structure can play a role in reinforcing and strengthening the connecting components, which helps to improve the strength and stability of the overall structure, reduce deformation, and extend the service life.

[0048] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the flange plate 10 of the middle section 100 , the flange plate 10 of the first kingpin mounting section 200 , and the flange plate 10 of the second kingpin mounting section 200 are all constructed in a circular shape, and the fasteners 11 are evenly arranged along the circumference of the flange plate 10 .

[0049] The uniform arrangement of the fasteners 11 along the circumference of the flange plate 10 can achieve uniform force distribution, ensure balanced force at the connection, reduce stress concentration caused by excessive local force, and help improve the bearing capacity and stability of the connection. The uniform arrangement of the fasteners 11 can effectively share the force of the connection, and at the same time prevent the fasteners 11 from loosening or falling off due to uneven force during vibration or movement, thereby ensuring the safety and reliability of the connection. In addition, the uniform arrangement of the fasteners 11 can reduce stress concentration at the connection, reduce the possibility of fatigue damage, extend the service life of the connection, and improve the reliability and stability of the overall structure.

[0050] In some specific embodiments of the present invention, Figure 1 As shown, the two ends of the middle section 100 extend upward at an angle, and the flange plate 10 is perpendicular to the extension direction of the two ends of the middle section 100. The flange plate 10 is perpendicular to the extension direction of the two ends of the middle section 100, which can make the connection more stable, ensure the verticality and parallelism of the connecting parts, improve the overall stability of the front axle beam 1 structure, and make the vehicle more stable during driving. In addition, the structure of the middle section 100 extending upward at an angle can optimize the geometric shape of the front axle beam 1, which is conducive to lowering the center of gravity, improving the handling performance of the vehicle, making the vehicle more stable during cornering and rapid acceleration, and improving the driving experience.

[0051] In some specific embodiments of the present invention, Figure 1 and Figure 3As shown, the first kingpin mounting section 200 and the second kingpin mounting section 300 both penetrate the limiting hole 12 of the first kingpin mounting hole 201 in the front-to-back direction. The limiting hole 12 of the first kingpin mounting section 200 is suitable for penetrating a limiting member to limit the pin shaft in the first kingpin mounting hole 201, and the limiting hole 12 of the second kingpin mounting section 300 is suitable for penetrating a limiting member to limit the pin shaft in the second kingpin mounting hole 301.

[0052] A limiting member is passed through the limiting hole 12 to fix the pins in the first kingpin mounting hole 201 and the second kingpin mounting hole 300. The limiting member is kept fixed with the first kingpin mounting section 200 and the second kingpin mounting section 300, and cooperates with the pins in the first kingpin mounting hole 201 and the second kingpin mounting hole 301 to limit the relative position between the limiting member and the pin, thereby ensuring the fixation of the first pin mounting section 200, the second pin mounting section 200 and the pin.
