[0015] Compared to existing technologies, the chassis assembly described in this application has the following advantages:

[0016] 1) The long longitudinal tie rod mounting bracket includes a crossbeam connecting bracket and a long longitudinal bracket. The crossbeam connecting bracket and the long longitudinal bracket together form a long longitudinal tie rod mounting cavity to improve the strength and rigidity of the long longitudinal tie rod mounting bracket, which helps to reduce the probability of cracking and damage of the long longitudinal tie rod mounting bracket.

[0018] (3) The upper end of the crossbeam connecting outer plate forms an S-shaped connecting edge line that is close to the longitudinal beam, which helps to reduce stress concentration at the connection between the extension section of the connecting outer plate and the longitudinal beam, and helps to reduce the risk of local cracking of the frame assembly.

[0019] (4) The upper end of the crossbeam connecting bracket forms a connecting opening with the opening size gradually increasing from front to back, which is conducive to increasing the contact area between the crossbeam connecting bracket and the longitudinal beam, improving the integrity of the crossbeam connecting bracket and the longitudinal beam, further improving the connection strength between the crossbeam connecting bracket and the longitudinal beam, and also improving the connection strength between the long longitudinal tie rod mounting bracket and the longitudinal beam.

Detailed Implementation

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0039] The following will refer to the appendix. Figure 1 - Appendix Figure 6 The frame assembly 100 of this application will be described in detail with reference to embodiments. The frame assembly 100 can be installed on a vehicle.

[0040] The frame assembly 100 may include:

[0041] The front axle is connected to longitudinal beam 1 via a five-bar linkage.

[0042] Two sets of long longitudinal tie rod mounting brackets 3 are provided, each set of long longitudinal tie rod mounting brackets 3 is provided on the longitudinal beam 1, and the third cross beam 23 connects the two sets of long longitudinal tie rod mounting brackets 3;

[0043] Two sets of short longitudinal tie rod mounting brackets 4 are provided on the longitudinal beam 1;

[0044] Front cross brace support, the front cross brace support is set on a longitudinal beam 1;

[0045] The linkage assembly includes a lateral tie rod, two long longitudinal tie rods, and two short longitudinal tie rods. Each long longitudinal tie rod is connected to the front axle and a set of long longitudinal tie rod mounting brackets 3, and each short longitudinal tie rod is connected to the front axle and a set of short longitudinal tie rod mounting brackets 4. The lateral tie rod is laterally positioned and connected to the front lateral tie rod bracket and the front axle. By setting up two long longitudinal tie rods, two short longitudinal tie rods, and a lateral tie rod, the frame assembly 100 can form a five-link mechanism. The five-link mechanism on the frame assembly 100 helps to improve the stability and off-road performance of the entire vehicle.

[0046] In this application, the crossbeam connecting bracket 31 and the long longitudinal bracket 32 ​​cooperate to form the long longitudinal tie rod mounting bracket 3. The long longitudinal tie rod mounting bracket 3 is used to install the long longitudinal tie rod, and the other end of the long longitudinal tie rod is connected to the front axle. The short longitudinal tie rod mounting bracket 4 is used to install the short longitudinal tie rod, and the other end of the short longitudinal tie rod is connected to the front axle.

[0047] According to the first aspect of the present invention, the frame assembly 100, such as Figure 1 - Figure 6 As shown, the frame assembly 100 may include a longitudinal beam 1 and a long longitudinal tie rod mounting bracket 3. The long longitudinal tie rod mounting bracket 3 includes a crossbeam connecting bracket 31 and a long longitudinal bracket 32. The crossbeam connecting bracket 31 is connected to the lower part of the longitudinal beam 1 and is used to connect and cooperate with the third crossbeam 23. The crossbeam connecting bracket 31 includes a crossbeam connecting inner plate 311 and a crossbeam connecting outer plate 312 that are fastened together along the Y direction. The long longitudinal bracket 32 ​​is connected to the crossbeam connecting outer plate 312 and together with the crossbeam connecting outer plate 312 to form a long longitudinal tie rod mounting cavity 301. One end of the long longitudinal tie rod is connected to the long longitudinal bracket 32 ​​and the crossbeam connecting outer plate 312.

[0048] It should be noted that in front solid axle models, the long longitudinal tie rod mounting bracket is relatively weak, and the overall frame torsional stiffness is low. During heavy off-road driving, problems such as cracking of the long longitudinal tie rod mounting bracket and severe frame deformation leading to abnormal noises may occur.

[0049] Based on this, this application provides a vehicle frame assembly 100, which may include a longitudinal beam 1 and a long longitudinal tie rod mounting bracket 3. The longitudinal beam 1 can extend along the longitudinal direction of the vehicle, and the long longitudinal tie rod mounting bracket 3 can be used to mount long longitudinal tie rods. When the vehicle frame assembly 100 is as follows... Figure 1When setting the direction, the vehicle's forward and backward directions can be... Figure 1 The longitudinal tie rod mounting bracket 3 may include a crossbeam connecting bracket 31 and a long longitudinal bracket 32. The crossbeam connecting bracket 31 may be located below the longitudinal beam 1 and may be welded to the longitudinal beam 1. The crossbeam connecting bracket 31 may be used to connect and cooperate with the third crossbeam 23. The crossbeam connecting bracket 31 may be bolted to the third crossbeam 23 and may be located on the outer side of the third crossbeam 23. It should be noted that "outer side of the third crossbeam 23" refers to the side of the third crossbeam 23 away from the centerline of the frame assembly 100 in the Y direction (i.e., the left-right direction of the frame assembly 100).

[0050] The crossbeam connecting bracket 31 may include a crossbeam connecting inner plate 311 and a crossbeam connecting outer plate 312. The crossbeam connecting inner plate 311 and the crossbeam connecting outer plate 312 can be fastened together along the Y direction. When the frame assembly is 100 Figure 1 When setting the direction, the Y direction can be... Figure 1 The Y-axis in the equation can be parallel to the left and right directions of the vehicle. For example... Figure 2 As shown, the inner crossbeam connecting plate 311 and the outer crossbeam connecting plate 312 can be arranged along the Y direction, with the outer crossbeam connecting plate 312 located outside the inner crossbeam connecting plate 311. The inner crossbeam connecting plate 311 and the outer crossbeam connecting plate 312 can be fitted together along the Y direction to jointly define the first cavity 313. The first cavity 313 can be open towards the longitudinal beam 1. By providing the crossbeam connecting bracket 31 to form the first cavity 313, the rigidity of the crossbeam connecting bracket 31 can be improved. It should be noted that "outer side of the inner crossbeam connecting plate 311" refers to the side of the inner crossbeam connecting plate 311 in the Y direction away from the centerline of the frame assembly 100.

[0051] like Figure 2 and Figure 5As shown, the longitudinal support 32 can be connected to the outer plate 312 of the crossbeam connection. The longitudinal support 32 can be welded to the outer plate 312 of the crossbeam connection. The longitudinal support 32 can be located on the side of the outer plate 312 of the crossbeam connection away from the inner plate 311 of the crossbeam connection. The outer plate 312 of the crossbeam connection can support the longitudinal support 32. The crossbeam connection bracket 31 can cooperate with the longitudinal support 32 to form the longitudinal tie rod mounting bracket 3. At least a part of the longitudinal support 32 can be spaced apart from the outer plate 312 of the crossbeam connection. The longitudinal support 32 and the outer plate 312 of the crossbeam connection can enclose the longitudinal tie rod mounting cavity 301. One end of the longitudinal tie rod can be installed in the longitudinal tie rod mounting cavity 301. Part of the longitudinal tie rod mounting cavity 301 can be open to the front, so that the longitudinal tie rod can be arranged in the front-rear direction. One end of the longitudinal tie rod can be connected to the longitudinal support 32 and the outer plate 312 of the crossbeam connection respectively, and the other end of the longitudinal tie rod can be connected to the front axle. It should be noted that the "front side" in the phrase "the part of the longitudinal tie rod mounting cavity 301 can be opened to the front" refers to the side of the longitudinal tie rod mounting cavity 301 closer to the front of the vehicle along the longitudinal direction of the vehicle.

[0052] By setting one end of the long longitudinal tie rod to be connected to the long longitudinal support 32 and the crossbeam connecting outer plate 312 respectively, it is beneficial to enhance the ability of the long longitudinal tie rod mounting bracket 3 to support the long longitudinal tie rod. The force on the long longitudinal tie rod can be evenly transmitted to the long longitudinal support 32 and the crossbeam connecting outer plate 312, which can reduce the stress concentration phenomenon on the long longitudinal tie rod mounting bracket 3, improve the strength and rigidity of the long longitudinal tie rod mounting bracket 3, and reduce the probability of cracking and damage of the long longitudinal tie rod mounting bracket 3.

[0053] like Figure 1 As shown, the crossbeam connecting bracket 31 can be connected to the longitudinal beam 1, and the long longitudinal tie rod mounting bracket 3 can be connected to the longitudinal beam 1 through the crossbeam connecting bracket 31. The crossbeam connecting bracket 31 can also be connected and cooperate with the third crossbeam 23. The third crossbeam 23 can be provided with crossbeam connecting brackets 31 at both ends along the left and right directions of the vehicle. The third crossbeam 23 can be connected between the two sets of long longitudinal tie rod mounting brackets 3. The two sets of long longitudinal tie rod mounting brackets 3 can be connected through the third crossbeam 23, and the two sets of long longitudinal tie rod mounting brackets 3 can also be connected to the longitudinal beam 1 respectively. This is beneficial for optimizing the force transmission path of the frame assembly 100, improving the overall torsional stiffness of the frame assembly 100, providing good rigidity for the frame assembly 100 under strong off-road conditions, and reducing the deformation of the frame assembly 100.

[0054] In this embodiment, the crossbeam connecting bracket 31 and the long longitudinal bracket 32 ​​together constitute the long longitudinal tie rod mounting bracket 3, which is beneficial to improving the strength and rigidity of the long longitudinal tie rod mounting bracket 3 and reducing the probability of cracking or damage to the long longitudinal tie rod mounting bracket 3.

[0055] In some embodiments of this application, the longitudinal support 32 is formed with a groove structure that opens to the side of the crossbeam connecting support 31, and part of the crossbeam connecting outer plate 312 is disposed in the groove structure and is fitted to the inner surface of the longitudinal support 32.

[0056] The longitudinal support 32 can form a grooved structure. When the longitudinal support 32 is assembled with the crossbeam connecting support 31, the grooved structure can be open towards the side of the longitudinal support 32 facing the crossbeam connecting support 31. Part of the structure of the crossbeam connecting outer plate 312 can be set inside the grooved structure. The crossbeam connecting outer plate 312 set inside the grooved structure can be fitted to the inner surface of the longitudinal support 32. The crossbeam connecting outer plate 312 set inside the grooved structure can be welded to the longitudinal support 32. This is beneficial to increasing the contact area between the longitudinal support 32 and the crossbeam connecting outer plate 312, enhancing the connection strength between the longitudinal support 32 and the crossbeam connecting outer plate 312, and further improving the strength and rigidity of the longitudinal tie rod mounting bracket 3.

[0057] At least part of the trough structure can be constructed as a long longitudinal tie rod mounting cavity 301. The long longitudinal support 32 can be together with the outer plate 312 of the crossbeam connection located in the trough structure to form the long longitudinal tie rod mounting cavity 301. The long longitudinal tie rod can be connected to the long longitudinal support 32 and the outer plate 312 of the crossbeam connection located in the trough structure by bolts.

[0058] In some embodiments of this application, such as Figure 2 and Figure 5 As shown, the long longitudinal support 32 is provided with a second opening 321. The second opening 321 is provided through the long longitudinal support 32 along the thickness direction and is used to fill the welding material so as to weld the long longitudinal support 32 to the crossbeam connecting outer plate 312.

[0059] The longitudinal support 32 may have a second opening 321, which extends through the longitudinal support 32 along its thickness. The second opening 321 can be used to fill with solder, which can then contact and engage with the outer plate 312 connecting the crossbeam, thereby achieving the effect of welding the longitudinal support 32 to the outer plate 312 at the second opening 321. By providing the second opening 321, the connection strength between the longitudinal support 32 and the outer plate 312 connecting the crossbeam can be further improved, which is beneficial for further improving the strength and rigidity of the longitudinal tie rod mounting bracket 3.

[0060] Part of the structure of the crossbeam connecting outer plate 312 is located within the groove structure of the longitudinal support 32. The longitudinal support 32 and the crossbeam connecting outer plate 312 can be arranged opposite each other along the Y direction. When the longitudinal support 32 and the crossbeam connecting outer plate 312 need to be welded together, if the welding operation is performed from the inside of the groove structure, the welding equipment needs to be extended into the groove structure. The operating space inside the groove structure is small, which can easily lead to interference between the welding equipment and the longitudinal support 32, thus making the welding of the longitudinal support 32 and the crossbeam connecting outer plate 312 difficult. Therefore, a second opening 321 is provided so that the welding process can be carried out on the side of the longitudinal support 32 away from the crossbeam connecting outer plate 312, which helps to reduce the connection difficulty of the longitudinal support 32 and the crossbeam connecting outer plate 312 and facilitates operation. The specific location of the second opening 321 can be set according to the specific structure of the longitudinal support 32 and the crossbeam connecting outer plate 312 and the connection requirements. The location of the second opening 321 can be set in an area on the longitudinal support 32 that is easy to operate. As an example, the chamfer of the long longitudinal support 32 is subjected to greater stress, making welding difficult.

[0061] In some embodiments of this application, such as Figure 2 As shown, the crossbeam connecting outer plate 312 includes a connecting outer plate extension section 3121 extending forward and upward. The connecting outer plate extension section 3121 is connected to the outer side wall and bottom wall of the longitudinal beam 1. The upper end of the crossbeam connecting outer plate 312 forms a connecting edge line that is attached to the longitudinal beam 1 and forms an S-shape.

[0062] The crossbeam connecting outer plate 312 may include a connecting outer plate extension 3121, which extends forward and upward. The connecting outer plate extension 3121 can be located at the upper end of the crossbeam connecting outer plate 312. The connecting outer plate extension 3121 increases the contact area between the crossbeam connecting outer plate 312 and the longitudinal beam 1, which is beneficial for improving the connection strength between the crossbeam connecting outer plate 312 and the longitudinal beam 1. The connecting outer plate extension 3121 can be connected to both the outer wall and the bottom wall of the longitudinal beam 1 by welding, thereby forming a connecting edge line at the upper end of the crossbeam connecting outer plate 312 that fits snugly against the longitudinal beam 1. The connecting edge line can be S-shaped, and the connection edge line can be the welding mating position between the connecting outer plate extension 3121 and the longitudinal beam 1; that is, the weld bead at the connection between the connecting outer plate extension 3121 and the longitudinal beam 1 can extend in an S-shape. By setting the connection edge structure to an S-shape, the stress at the connection edge can be optimized, which helps to reduce stress concentration at the connection between the outer plate extension section 3121 and the longitudinal beam 1, and helps to reduce the risk of local cracking of the frame assembly 100.

[0063] In some embodiments of this application, such as Figure 2 As shown, the upper end of the crossbeam connecting bracket 31 forms a connecting opening with a gradually increasing opening size from front to back, and the connecting opening is used to connect and cooperate with the longitudinal beam 1.

[0064] The upper end of the crossbeam connecting bracket 31 can be open towards the longitudinal beam 1, and a connection opening can be formed at the upper end of the crossbeam connecting bracket 31. The crossbeam connecting bracket 31 located at the connection opening can be connected and fitted with the longitudinal beam 1, and the crossbeam connecting bracket 31 located at the connection opening can be welded to the longitudinal beam 1. The opening size of the connection opening can gradually increase from front to back along the front-rear direction of the vehicle, that is, the connection opening can be gradually widened to the rear. Along the front-rear direction of the vehicle, the width dimension of the longitudinal beam 1 in the Y direction gradually increases from front to back, and the opening size of the connection opening can be adapted to the width dimension of the longitudinal beam 1, so that the crossbeam connecting bracket 31 can better fit and assemble with the longitudinal beam 1, which is conducive to further increasing the contact area between the crossbeam connecting bracket 31 and the longitudinal beam 1, which is conducive to improving the overall integrity of the crossbeam connecting bracket 31 and the longitudinal beam 1, which is conducive to further improving the connection strength between the crossbeam connecting bracket 31 and the longitudinal beam 1, and can also improve the connection strength between the long longitudinal tie rod mounting bracket 3 and the longitudinal beam 1.

[0065] In some embodiments of this application, such as Figure 1 - Figure 4 As shown, the frame assembly 100 also includes a short longitudinal tie rod mounting bracket 4. The short longitudinal tie rod mounting bracket 4 is located on the front side of the long longitudinal bracket 32 ​​and the crossbeam connecting bracket 31, and is connected to the crossbeam connecting bracket 31, the long longitudinal bracket 32 ​​and the longitudinal beam 1. The short longitudinal tie rod mounting bracket 4 forms a short longitudinal tie rod mounting cavity 401, and one end of the short longitudinal tie rod is connected to the short longitudinal tie rod mounting bracket 4.

[0066] The short longitudinal tie rod mounting bracket 4 can be located in front of the long longitudinal bracket 32 ​​and the crossbeam connecting bracket 31, and can be positioned below the longitudinal beam 1. The short longitudinal tie rod mounting bracket 4 can be connected to the crossbeam connecting bracket 31, the long longitudinal bracket 32, and the longitudinal beam 1 respectively. The short longitudinal tie rod mounting bracket 4 can be welded to the crossbeam connecting bracket 31, the long longitudinal bracket 32, and the longitudinal beam 1. The short longitudinal tie rod mounting bracket 4 can form a short longitudinal tie rod mounting cavity 401. One end of the short longitudinal tie rod can be installed inside the short longitudinal tie rod mounting cavity 401. A portion of the short longitudinal tie rod mounting cavity 401 can be open to the front, allowing the short longitudinal tie rod to be arranged in the front-rear direction. One end of the short longitudinal tie rod can be connected to the short longitudinal tie rod mounting bracket 4, and the other end can be connected to the front axle.

[0067] It should be noted that the front side of the longitudinal support 32 and the crossbeam connecting support 31 refers to the side of the longitudinal support 32 and the crossbeam connecting support 31 that is closer to the front of the vehicle along the longitudinal direction of the vehicle.

[0068] The short longitudinal tie rod mounting bracket 4 can be used to install short longitudinal tie rods, and the long longitudinal tie rod mounting bracket 3 can be used to install long longitudinal tie rods. By setting the short longitudinal tie rod mounting bracket 4, it can be connected to the crossbeam connecting bracket 31 and the long longitudinal bracket 32 ​​respectively, so that the short longitudinal tie rod mounting bracket 4 and the long longitudinal tie rod mounting bracket 3 can be constructed as a whole, which is conducive to strengthening the overall structural strength of the short longitudinal tie rod mounting bracket 4 and the long longitudinal tie rod mounting bracket 3, and is conducive to strengthening the structural strength of the frame assembly 100.

[0069] like Figure 1 As shown, the crossbeam connecting bracket 31 can be connected to the longitudinal beam 1, and the short longitudinal tie rod mounting bracket 4 can be connected to the crossbeam connecting bracket 31, the long longitudinal bracket 32, and the longitudinal beam 1. The two sets of short longitudinal tie rod mounting brackets 4 can be connected through the third crossbeam 23, and the two sets of short longitudinal tie rod mounting brackets 4 can also be connected to the longitudinal beam 1 respectively. This is beneficial for further optimizing the force transmission path of the frame assembly 100, further improving the overall torsional stiffness of the frame assembly 100, providing good rigidity for the vehicle body under strong off-road conditions, and further reducing the deformation of the frame assembly 100.

[0070] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 6 As shown, the short longitudinal tie rod mounting bracket 4 includes: a short longitudinal bracket inner plate 41 and a short longitudinal bracket outer plate 42. The short longitudinal bracket inner plate 41 is connected to the crossbeam connecting inner plate 311 and the longitudinal beam 1 respectively. The short longitudinal bracket outer plate 42 is connected to the long longitudinal bracket 32 ​​and the longitudinal beam 1 respectively. The short longitudinal bracket outer plate 42 and the short longitudinal bracket inner plate 41 are fastened together along the Y direction and enclosed to form a short longitudinal tie rod mounting cavity 401.

[0071] The inner plate 41 and outer plate 42 of the short longitudinal support can be arranged along the Y-direction, with the outer plate 42 located outside the inner plate 41. It should be noted that "outer side of the inner plate 41" refers to the side of the inner plate 41 away from the centerline of the frame assembly 100 in the Y-direction. The inner plate 41 can be connected to both the crossbeam connecting inner plate 311 and the longitudinal beam 1, and can be welded to both. The outer plate 42 of the short longitudinal support can be connected to both the long longitudinal support 32 and the longitudinal beam 1, and can be welded to both. The long longitudinal support 32 can be located between the outer plate 312 and the outer plate 42. By setting the short longitudinal support outer plate 42, it can be connected to the long longitudinal support 32 and the longitudinal beam 1 respectively, which can effectively transfer the force of the long longitudinal support 32 on the crossbeam connecting outer plate 312 to the longitudinal beam 1.

[0072] At least a portion of the outer plate 42 of the short longitudinal support can be spaced apart from at least a portion of the inner plate 41 of the short longitudinal support along the Y direction. The outer plate 42 and the inner plate 41 of the short longitudinal support can be fastened together along the Y direction. The outer plate 42 and the inner plate 41 of the short longitudinal support can enclose to form a short longitudinal tie rod mounting cavity 401. One end of the short longitudinal tie rod can be installed in the short longitudinal tie rod mounting cavity 401. One end of the short longitudinal tie rod can be connected to both the outer plate 42 and the inner plate 41 of the short longitudinal support. The short longitudinal tie rod can be bolted to the outer plate 42 and to the inner plate 41 of the short longitudinal support. By setting one end of the short longitudinal tie rod to be connected to the outer plate 42 and the inner plate 41 of the short longitudinal support respectively, it is beneficial to enhance the ability of the short longitudinal tie rod mounting bracket 4 to support the short longitudinal tie rod. The force on the short longitudinal tie rod can be evenly transmitted to the outer plate 42 and the inner plate 41 of the short longitudinal support, which can reduce the stress concentration phenomenon on the short longitudinal tie rod mounting bracket 4, improve the strength and rigidity of the short longitudinal tie rod mounting bracket 4, and reduce the probability of cracking and damage of the short longitudinal tie rod mounting bracket 4.

[0073] In some embodiments of this application, such as Figure 2 As shown, the rear end of the short longitudinal support outer plate 42 is provided with an outwardly folded short longitudinal support outer plate flange 421, which is connected and cooperates with the front side wall of the long longitudinal support 32.

[0074] The rear end of the short longitudinal support outer plate 42 can be provided with an outwardly folded-out flange 421.

The short longitudinal support outer plate flange 421 can be connected and fitted to the front side wall of the long longitudinal support 32. The short longitudinal support outer plate flange 421 can be arranged to fit against the front side wall of the long longitudinal support 32 by overlapping from front to back. As an example, the short longitudinal support outer plate flange 421 and the front side wall of the long longitudinal support 32 can preferably fit conformally, and the shape of the short longitudinal support outer plate flange 421 can be adapted to the front side wall of the long longitudinal support 32.

[0075] By setting the flange 421 on the outer plate of the short longitudinal support, the contact area between the outer plate 42 of the short longitudinal support and the long longitudinal support 32 can be increased. A local double-layer plate structure can be formed between the outer plate 42 of the short longitudinal support and the long longitudinal support 32, which is conducive to improving the connection strength between the outer plate 42 of the short longitudinal support and the long longitudinal support 32, and is conducive to further strengthening the overall structural strength of the short longitudinal tie rod mounting bracket 4 and the long longitudinal tie rod mounting bracket 3, and is conducive to further enhancing the structural strength of the frame assembly 100.
