[0049] Example 1

[0050] like Figures 1 to 4 As shown, this embodiment provides a front axle assembly having X-direction, Y-direction and Z-direction intersecting with each other.

[0051] In some embodiments, the X direction, the Y direction, and the Z direction intersect each other perpendicularly.

[0052] In some embodiments, the front axle assembly includes a main beam 10, a beam mounting bracket 20 and a control arm mounting bracket 30, wherein the beam mounting bracket 20 is used to connect to the vehicle body, the control arm mounting bracket 30 is used to connect to the control arm, the beam mounting bracket 20 is relatively arranged at two ends of the main beam 10 along the Y direction, and the control arm mounting bracket 30 is arranged on the side of the beam mounting bracket 20 away from the main beam 10.

[0053] In a specific embodiment, the main beam 10 includes a straight portion 11 and a bent portion 12, the straight portion 11 extends along the Y direction, and the bent portion 12 is arranged at opposite ends of the straight portion 11 along the Y direction; the beam mounting bracket 20 is arranged at one end of the bent portion 12 away from the straight portion 11; the control arm mounting bracket 30 is connected to the side of the beam mounting bracket 20 away from the main beam 10; in this way, by connecting the control arm mounting bracket 30 with the beam mounting bracket 20 and then integrating it into the bent portion 12 of the main beam 10, when the beam mounting bracket 20 is assembled and connected to the vehicle body, most of the vibration of the road surface, the vibration of the air-conditioning compressor or the vibration of the powertrain is transmitted to the vehicle body through the beam mounting bracket 20, and a small part is transmitted through the main beam 10, thereby changing the decoupling mode of the force in the X direction, Y direction and Z direction, so that the transmission of force is no longer concentrated on the main beam 10, thereby reducing the manufacturing requirements for the main beam 10, and at the same time, the control arm mounting bracket 30 and the beam mounting bracket 20 are connected. The connection is then connected to the main beam 10. On the one hand, the welding deformation of the main beam 10 and the beam mounting bracket 20 and the control arm mounting bracket 30 is reduced, and the quality stability is improved. On the other hand, the control arm can also transmit most of the vibration to the vehicle body through the control arm mounting bracket and the beam mounting bracket, further improving the force decoupling method and reducing the manufacturing requirements for the main beam. In order to further reduce the manufacturing requirements of the main beam 10, the angle formed by the axis of the straight portion 11 and the bent portion 12 is θ; and the angle θ is limited to satisfy: 10°≤θ≤40°; thereby, the bending degree of the bent portion 12 can be reduced, and the force transmission can be more easily achieved. After the main beam 10 is connected to the vehicle body through the beam mounting bracket 20, the force can be transmitted to the vehicle body through the beam mounting bracket 20, which improves the force decoupling method in the X, Y and Z directions, and at the same time reduces the stiffness and strength manufacturing requirements of the main beam 10 under large bending, thereby reducing the manufacturing cost.

[0054] It should be noted that when the angle θ is less than 10°, the bending amplitude of the straight portion 11 and the bent portion 12 is too small. At this time, most of the Y-direction force is concentrated on the main beam 10, and the decoupling of the Y-direction force is small, and the decoupling of the force in the Y-direction cannot be improved; when the angle θ is greater than 40°, the bending amplitude of the straight portion 11 and the bent portion 12 is too large. At this time, the Y-direction force is concentrated on the bent portion 12. Although the decoupling of the Y-direction force can be improved, the excessive force on the bent portion 12 also increases the stiffness and strength manufacturing requirements of the main beam 10, and the manufacturing cost cannot be reduced.

[0055] In some embodiments, in order to further achieve force decoupling and reduce the manufacturing requirements of the main beam 10, the front axle assembly also includes a first reinforcement 40, which is respectively connected to the bending portion 12 and the beam mounting bracket 20; thereby, the overall stiffness of the main beam 10 can be improved to meet the stiffness requirements of the main beam 10 under the action of Y-direction force, while reducing the manufacturing requirements of the main beam 10 itself to balance the lightweight and dynamic performance of the front axle assembly.

[0056] In some embodiments, the angle θ is preferably 25°.

[0057] In some embodiments, in order to improve the structural rigidity and strength of the beam mounting bracket 20, a first flange 21 is provided at the side edge of the beam mounting bracket 20, and the first flange 21 extends toward the side facing away from the main beam 10. This design makes it difficult for the beam mounting bracket 20 to deform when subjected to force, thereby improving the quality of the front axle assembly.

[0058] In some embodiments, the beam mounting bracket 20 is an L-shaped structure, which includes a first panel 20a and a second panel 20b, wherein the first panel 20a is provided with an opening 22, and the function of the opening 22 is to connect the first panel 20a to the vehicle body, and the second panel 20b is welded to the main beam 10, and the control arm mounting bracket 30 is welded to the end of the second panel 20b facing away from the main beam 10, and the control arm mounting bracket 30 is welded to the first panel 20a, thereby integrating the existing split arrangement structure into one, which can effectively realize force transmission and decoupling, thereby reducing the manufacturing requirements for the main beam 10, while reducing the number of brackets and simplifying the subsequent process flow.

[0059] In some embodiments, the front axle assembly also includes a steering gear mounting bracket 50, which is used for installing the automobile steering gear, wherein the steering gear mounting bracket 50 is arranged relative to the outer peripheral wall of the main beam 10 in the Y direction, and the steering gear mounting bracket 50 is located at the connection between the straight portion 11 and the bent portion 12, so that the strength and rigidity of the connection between the straight portion 11 and the bent portion 12 can be enhanced to meet the performance requirements of the main beam 10 while reducing the manufacturing requirements of the main beam 10.

[0060] In some embodiments, the steering gear mounting bracket 50 includes a first rib portion 51 and a first mounting portion 52. The first rib portion 51 is connected to the main beam 10, and the first mounting portion 52 is connected to the first rib portion 51. By setting the first rib portion 51, the stiffness of the steering gear mounting bracket 50 in the X direction can be improved to avoid deformation of the steering gear mounting bracket 50 when subjected to force.

[0061] In some embodiments, in order to further improve the stiffness of the steering gear mounting bracket 50, the steering gear mounting bracket 50 also includes a second reinforcement 54, and the second reinforcement 54 is connected to the first rib portion 51 and the main beam 10 to further improve the stiffness of the steering gear mounting bracket 50 in the Z direction and improve the load-bearing performance.

[0062] In some embodiments, the first rib portion 51 and the second reinforcement member 54 are both provided with positioning holes 55 for positioning the steering gear. By providing the positioning holes 55, the steering gear can be quickly positioned and installed to improve assembly efficiency.

[0063] In some embodiments, the width of the first rib portion 51 in the Y direction gradually increases from one end close to the first mounting portion 52 to the end away from the first mounting portion 52, so that the first rib portion 51 has an outward-facing structure in the Y direction, thereby increasing the contact area between the first rib portion 51 and the main beam 10 in the Y direction, so as to improve the stiffness of the steering gear mounting bracket 50 in the Y direction.

[0064] In some embodiments, in order to further improve the stiffness of the steering gear mounting bracket 50 in the Y direction, a second flange 53 is provided at the side edge of the steering gear mounting bracket 50, and the second flange 53 is connected to the main beam 10, so as to improve the stiffness of the steering gear mounting bracket 50. At the same time, the second flange 53 can increase the contact area with the main beam 10, thereby improving the connection strength between the steering gear mounting bracket 50 and the main beam 10, thereby ensuring the stability of the steering gear after installation.

[0065] In some embodiments, the front axle assembly also includes an air-conditioning compressor mounting bracket 60, and the air-conditioning compressor mounting bracket 60 includes a first bracket 61 and a second bracket 62 that are relatively arranged on both sides of the main beam 10 along the X-direction. By relatively arranging the first bracket 61 and the second bracket 62, the material utilization rate can be improved while ensuring the stability of the installation of the air-conditioning compressor, thereby reducing the manufacturing cost.

[0066] In the above embodiment, the first bracket 61 is provided with a third reinforcement member 63, and the third reinforcement member 63 is connected to the main beam 10 to improve the rigidity of the first bracket 61 in the Z direction, thereby ensuring the installation stability of the air-conditioning compressor.

[0067] In other embodiments, the second bracket 62 may also be provided with a third reinforcement member 63 to improve the rigidity of the second bracket 62 in the Z direction.

[0068] In some embodiments, the first bracket 61 and the second bracket 62 both include a second rib portion 601 and a second mounting portion 602; wherein, the second rib portion 601 is connected to the main beam 10, and the second mounting portion 602 is arranged at an end of the second rib portion 601 away from the main beam 10; by setting the second rib portion 601, the rigidity of the air-conditioning compressor mounting bracket 60 in the X direction can be improved to avoid deformation of the air-conditioning compressor mounting bracket 50 when subjected to force; further, in order to ensure stability after installation, the first bracket 61 and the second bracket 62 both include two second mounting portions 602, and the two second mounting portions 602 are arranged opposite to each other in the Y direction, thereby providing support stability for the air-conditioning compressor mounting bracket 60.

[0069] In some embodiments, in order to improve the installation efficiency, the first bracket 61 and the second bracket 62 are further provided with a positioning portion 603, which is provided at an end of the second rib portion 601 away from the main beam 10, and the positioning portion 603 is connected to the second mounting portion 602 in the Y direction. Specifically, the positioning portion 603 is placed between the two second mounting portions 602 and forms an integral structure with the second mounting portion 602, thereby improving the installation efficiency while ensuring the rigidity of the first bracket 61 and the second bracket 62.

[0070] In some embodiments, the width of the second rib portion 601 in the Y direction gradually increases from one end close to the second mounting portion 602 to one end away from the second mounting portion 602, so that the second rib portion 601 has an outward-facing structure in the Y direction, thereby increasing the contact area between the second rib portion 601 and the main beam 10 in the Y direction, so as to improve the stiffness of the first bracket 61 and the second bracket 62 in the Y direction.

[0071] In some embodiments, a third flange 604 is provided on the side edge of the air-conditioning compressor mounting bracket 60, and the third flange 604 is connected to the main beam 10; thereby, the stiffness of the air-conditioning compressor mounting bracket 60 in the Y direction can be further improved. At the same time, the third flange 604 can increase the contact area between the air-conditioning compressor mounting bracket 60 and the main beam 10, thereby improving the connection strength between the air-conditioning compressor mounting bracket 60 and the main beam 10, thereby ensuring the stability of the air-conditioning compressor after installation.

The vehicle body is provided with a beam, a beam mounting bracket 20 is connected to the beam, and the control arm is connected to the control arm mounting bracket 30.

[0074] In summary, the present invention provides a front axle assembly and a vehicle, which are connected to the control arm mounting bracket 30 and the beam mounting bracket 20 and then integrated into the bending portion 12 of the main beam 10. Therefore, when the beam mounting bracket 20 is assembled and connected to the vehicle body, most of the vibration of the road surface, the vibration of the air-conditioning compressor or the vibration of the powertrain is transmitted to the vehicle body through the beam mounting bracket 20, and a small part is transmitted through the main beam 10, thereby changing the decoupling mode of the force in the X direction, the Y direction and the Z direction, so that the transmission of force is no longer concentrated on the main beam 10, thereby reducing the manufacturing requirements for the main beam 10. At the same time, the control arm mounting bracket 30 is connected to the beam mounting bracket 20 and then to the main beam. On the one hand, the welding deformation of the main beam 10 and the beam mounting bracket 20 and the control arm mounting bracket 30 is reduced, and the quality stability is improved. On the other hand, the control arm is connected to the beam mounting bracket 20 and the control arm mounting bracket 30. The arm mounting bracket 30 and the beam mounting bracket 20 can also transmit most of the vibration to the vehicle body, further improving the force decoupling method and reducing the manufacturing requirements for the main beam; secondly, the straight portion 11 and the bent portion 12 of the main beam 10 form an angle θ, and the angle of the angle θ is limited, so that the bending degree of the bent portion 12 relative to the straight portion 11 can be reduced, which can make it easier to achieve force transmission, improve the force decoupling method, and at the same time reduce the stiffness and strength manufacturing requirements of the main beam 10 under large bending, thereby reducing the manufacturing cost; in addition, by adding a first reinforcement 40 between the beam mounting bracket 20 and the main beam 10, the overall stiffness of the main beam 10 can be improved to meet the stiffness requirements of the main beam 10 under the action of Y-direction force, while reducing the manufacturing requirements of the main beam 10 itself to balance the lightweight and dynamic performance of the front axle assembly.
