Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to a tie rod bracket, a frame assembly, and a vehicle. Background Technology

[0002] Currently, due to space constraints, the front of the chassis assembly is usually matched with a double wishbone or MacPherson strut suspension. Because of the use of a double wishbone or MacPherson strut suspension, the suspension travel is short after the front axle is fixed to the chassis, which affects the overall passability and off-road performance of the vehicle.

[0003] In related technologies, the front tie rod bracket is limited by the space in the front section of the vehicle frame assembly, which makes it impossible to guarantee the structural strength of the front tie rod. This can easily lead to problems such as cracking or deformation, affecting the installation reliability of the tie rod. Utility Model Content

[0004] In view of this, this application aims to provide a horizontal tie rod bracket with high structural strength, which can improve the installation reliability of the horizontal tie rod.

[0011] According to some embodiments of this application, the rear plate of the horizontal tie rod bracket is provided with a bracket rear plate connecting plate segment extending to the rear side. The bracket rear plate connecting plate segment is connected and engaged with the lower wall surface of the longitudinal beam. The bracket rear plate connecting plate segment is vertically overlapped and connected to the connecting flange of the second reinforcing plate.

[0012] According to some embodiments of this application, the inner plate segment of the front plate of the horizontal tie rod bracket is connected to the inner side wall of the longitudinal beam, and the inner plate segment of the rear plate of the horizontal tie rod bracket is connected to the inner side wall of the longitudinal beam, and the inner plate segment of the front plate of the horizontal tie rod bracket and the inner plate segment of the rear plate of the horizontal tie rod bracket are connected and cooperated.

[0013] According to some embodiments of this application, one of the inner plate section of the front plate of the horizontal tie rod bracket and the inner plate section of the rear plate of the horizontal tie rod bracket is provided with a third filling port, which is used to weld the inner plate section of the front plate of the horizontal tie rod bracket and the inner plate section of the rear plate of the horizontal tie rod bracket together.

[0014] According to some embodiments of this application, at least one of the inner plate section of the front plate of the horizontal tie rod bracket and the inner plate section of the rear plate of the horizontal tie rod bracket is provided with a mounting hole, the mounting hole being disposed opposite to the inner sidewall of the longitudinal beam and used for the installation structure to pass through.

Detailed Implementation

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0037] The following will refer to the appendix. Figure 1 -7 The cross brace bracket 5 of this application will be described in detail with reference to the embodiments.

[0038] According to an embodiment of this application, the tie rod bracket 5 is used in the frame assembly 100, and the tie rod bracket 5 is connected and cooperates with the longitudinal beam 1 of the frame assembly 100 so as to form a tie rod mounting part 502 on the longitudinal beam 1 for mounting one end of the tie rod.

[0039] According to the vehicle frame assembly 100 of the present application embodiment, the vehicle frame assembly 100 is provided with a front axle, two sets of long longitudinal tie rod mounting brackets, two sets of short longitudinal tie rod mounting brackets and a set of transverse tie rod brackets 5, and the front axle and the above-mentioned bracket structures are all mounted on the longitudinal beam 1 and provide mounting points for the connecting rod assembly.

[0040] Furthermore, the frame assembly 100 also 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, and each short longitudinal tie rod is connected to the front axle and a set of short longitudinal tie rod mounting brackets. The lateral tie rod is arranged laterally and connected to the lateral tie rod bracket 5 and the front axle. Thus, a five-bar linkage is formed in the front section of the frame assembly 100, which helps to improve the vehicle's passability and off-road performance.

[0041] According to an embodiment of this application, the horizontal tie rod bracket 5 includes a front plate 51, a rear plate 52, and a reinforcing plate 53.

[0042] The front plate 51 and rear plate 52 of the tie rod bracket are fastened together in the front-rear direction, and are respectively connected to the longitudinal beam 1. The tie rod bracket reinforcing plate 53 is connected to the longitudinal beam 1, and is fastened to the front plate 51 and rear plate 52 from the outside to the inside, forming a cavity structure through the tie rod bracket reinforcing plate 53, the front plate 51, and the rear plate 52, thereby improving the structural strength and load-bearing capacity of the tie rod bracket 5. The "front-rear direction" mentioned above refers to the front-rear direction of the frame assembly 100.

[0043] It should be noted that the tie rod bracket reinforcing plate 53 is fastened from the outside to the inside along the Y-direction. The "Y-direction" refers to the width direction of the frame assembly 100, and the inside of the Y-direction refers to the side of the frame assembly 100 closer to the central axis, while the outside of the Y-direction refers to the side of the frame assembly 100 away from the central axis. In other words, in the tie rod bracket 5, the tie rod bracket reinforcing plate 53 is fastened from the outside to the inside in the Y-direction and connected to the tie rod bracket front plate 51 and tie rod bracket rear plate 52.

[0044] Currently, due to space constraints, the front of the chassis assembly 100 is typically fitted with a double wishbone or MacPherson strut suspension. Because the vehicle uses a double wishbone or MacPherson strut suspension, the suspension's travel is short after the front axle is fixed to the chassis, thus affecting the vehicle's passability and off-road performance. In other words, existing technical solutions do not include a design for placing the front tie rod in the front section of the chassis assembly 100.

[0045] In related technologies, the tie rod bracket 5 is limited by the arrangement space in the front section of the frame assembly 100, which cannot guarantee the structural strength of the front tie rod and is prone to cracking or deformation, affecting the installation reliability of the tie rod.

[0046] The horizontal tie rod bracket 5 in this embodiment is composed of a front plate 51, a rear plate 52, and a reinforcing plate 53. The front plate 51 and the rear plate 52 are fastened together in the front-back direction, and the reinforcing plate 53 is further fastened to the front plate 51 and the rear plate 52 from the outside to the inside to form a cavity structure. This can improve the load-bearing performance of the horizontal tie rod bracket 5 in the front-back and inside-out directions, and improve the installation reliability of the horizontal tie rod at the horizontal tie rod bracket 5.

[0047] Understandably, by fastening the front plate 51 and the rear plate 52 of the tie rod bracket together in the front-rear direction, the load-bearing capacity of the tie rod bracket 5 in the front-rear direction can be improved. Furthermore, the reinforcing plate 53 of the tie rod bracket is further fastened to the front plate 51 and the rear plate 52 of the tie rod bracket in the Y direction to improve the load-bearing capacity of the tie rod bracket 5 in the inner and outer directions. This can improve the stiffness of the tie rod bracket 5 in the lateral direction, so that the durability and lateral stiffness of the tie rod bracket 5 can meet the installation requirements of the tie rod.

[0048] Meanwhile, the tie rod mounting portion 502 in the tie rod bracket 5 is formed on the front plate 51 and the rear plate 52 of the tie rod bracket, so that one end of the tie rod is connected to the longitudinal beam 1 through the tie rod mounting portion 502 and the tie rod mounting engagement. The tie rod is arranged in the transverse direction in the frame assembly 100, and the other end of the tie rod is connected to the front axle. That is to say, an opening structure suitable for avoiding the inner tie rod can be formed in the area where the tie rod mounting portion 502 is formed on the front plate 51 and the rear plate 52 of the tie rod bracket, so as to prevent interference between the tie rod bracket 5 and the tie rod.

[0049] In this application, the cross tie rod bracket reinforcing plate 53 is fastened to the front plate 51 and the rear plate 52 of the cross tie rod bracket from the outside to the inside along the Y direction, so that the cross tie rod bracket reinforcing plate 53 can fully avoid the cross tie rod and further improve the rigidity of the cross tie rod bracket 5 in the lateral direction.

[0050] According to the embodiments of this application, the horizontal tie rod bracket 5 is connected and cooperated with the front plate 51 and the rear plate 52 of the horizontal tie rod bracket by the reinforcing plate of the horizontal tie rod bracket 5, which can fully improve the stiffness of the horizontal tie rod bracket 5 in the lateral direction, as well as the overall durability, fatigue resistance and strength of the horizontal tie rod bracket 5, and ensure the installation reliability of the horizontal tie rod.

[0051] In a further embodiment of this application, the cross brace support reinforcement plate 53 includes: a main reinforcement plate section 531 of the cross brace support, a front reinforcement plate section 532 of the cross brace support, and a rear reinforcement plate section 533 of the cross brace support.

[0052] The main reinforcing plate segment 531 of the horizontal tie rod bracket is located on the outer side of the longitudinal beam 1 in the Y direction and is connected to the longitudinal beam 1. The front reinforcing plate segment 532 of the horizontal tie rod bracket is connected to the front side of the main reinforcing plate segment 531 and is connected to the front plate 51 of the horizontal tie rod bracket. The rear reinforcing plate segment 533 of the horizontal tie rod bracket is arranged opposite to the front reinforcing plate segment 532 in the X direction and is connected to the rear side of the main reinforcing plate segment 531 and is connected to the rear plate 52 of the horizontal tie rod bracket.

[0053] Therefore, the reinforcing plate 53 of the horizontal tie rod bracket can be arranged and fixed in the front and rear directions respectively with the front plate 51 and the rear plate 52 of the horizontal tie rod bracket, thereby improving the connection effect of the reinforcing plate 53 at the front plate 51 and the rear plate 52 of the horizontal tie rod bracket. This allows the reinforcing plate 53 to form a cavity structure with the front plate 51 and the rear plate 52 of the horizontal tie rod bracket, thereby improving the lateral stiffness of the horizontal tie rod bracket 5.

[0054] Combination Figure 4 and Figure 7 As shown, the front reinforcing plate segment 532 and the rear reinforcing plate segment 533 of the horizontal tie rod bracket are arranged opposite each other in the front-rear direction, and the front reinforcing plate segment 532 and the rear reinforcing plate segment 533 of the horizontal tie rod bracket are connected by the main reinforcing plate segment 531 of the horizontal tie rod bracket, so that the reinforcing plate 53 of the horizontal tie rod bracket is constructed as a U-shaped plate structure that is open to the inside in the Y direction, which helps to improve the enclosure effect of the cavity structure of the horizontal tie rod bracket 5, thereby improving the lateral stiffness of the horizontal tie rod bracket 5.

[0055] In some embodiments of this application, the cross brace support reinforcing plate 53 is provided with a first reinforcing plate connecting flange 5341 that folds forward and extends to the side. The first reinforcing plate connecting flange 5341 is connected to the main reinforcing plate section 531 of the cross brace support and the front reinforcing plate section 532 of the cross brace support, and is respectively connected to the longitudinal beam 1 and the front plate 51 of the cross brace support.

[0056] Specifically, the first reinforcing plate connecting flange 5341 extends forward on the horizontal tie rod bracket reinforcing plate 53 to increase the corresponding area of ​​the horizontal tie rod bracket reinforcing plate 53 with the longitudinal beam 1 and the front plate 51 of the horizontal tie rod bracket, thereby ensuring the reliability of the connection between the horizontal tie rod bracket reinforcing plate 53 and the longitudinal beam 1 and the front plate 51 of the horizontal tie rod bracket.

[0057] Among them, some of the main reinforcing plate sections 531 of the horizontal tie rod bracket protrude upward from the front reinforcing plate section 532 of the horizontal tie rod bracket, so that the main reinforcing plate sections 531 of the horizontal tie rod bracket can correspond to the outer side wall of the longitudinal beam 1 in the inward and outward directions. Furthermore, the part of the first reinforcing plate connecting flange 5341 connected to the main reinforcing plate section 531 of the horizontal tie rod bracket is connected and cooperates with the longitudinal beam 1, and the part of the first reinforcing plate connecting flange 5341 connected to the front reinforcing plate section 532 of the horizontal tie rod bracket is connected and cooperates with the front plate 51 of the horizontal tie rod bracket.

[0058] In a further embodiment of this application, the front plate 51 of the horizontal tie rod bracket is provided with a front plate connecting plate segment 513 extending forward. The front plate connecting plate segment 513 is connected and engaged with the lower wall surface of the longitudinal beam 1. The front plate connecting plate segment 513 is vertically overlapped and connected to the first reinforcing plate connecting flange 5341, thereby forming a multi-layer structure at the front plate connecting plate segment 513, which helps to improve the local strength at the joint between the horizontal tie rod bracket 5 and the longitudinal beam 1 and reduce the risk of cracking at the joint between the horizontal tie rod bracket 5 and the longitudinal beam 1.

[0059] The front plate connecting segment 513 of the bracket is vertically aligned with the bottom wall of the longitudinal beam 1, and its upper surface is connected to the bottom wall of the longitudinal beam 1. (Refer to...) Figure 4 The front plate connecting plate segment 513 of the bracket can overlap the first reinforcing plate connecting flange 5341 to increase the contact area between the front plate 51 of the horizontal tie rod bracket and the reinforcing plate 53 of the horizontal tie rod bracket, thereby improving the structural strength of the horizontal tie rod bracket 5 in the front area.

[0060] In some embodiments of this application, the cross brace support reinforcing plate 53 is provided with a second reinforcing plate connecting flange 5342 that extends rearward and is connected to the main reinforcing plate section 531 and the rear reinforcing plate section 533 of the cross brace support. The second reinforcing plate connecting flange 5342 is connected to the longitudinal beam 1 and the rear plate 52 of the cross brace support, respectively.

[0061] Specifically, the second reinforcing plate connecting flange 5342 extends rearward on the horizontal tie rod bracket reinforcing plate 53 to increase the corresponding area of ​​the horizontal tie rod bracket reinforcing plate 53 with the longitudinal beam 1 and the horizontal tie rod bracket rear plate 52, thereby ensuring the reliability of the connection between the horizontal tie rod bracket reinforcing plate 53 and the longitudinal beam 1 and the horizontal tie rod bracket rear plate 52.

[0062] Among them, some of the main reinforcing plate sections 531 of the horizontal tie rod bracket protrude upward from the rear reinforcing plate section 533 of the horizontal tie rod bracket, so that the main reinforcing plate sections 531 of the horizontal tie rod bracket can correspond to the outer side wall of the longitudinal beam 1 in the inward and outward directions. Furthermore, the part of the second reinforcing plate connecting flange 5342 connected to the main reinforcing plate section 531 of the horizontal tie rod bracket is intercepted and cooperated with the longitudinal beam 1, and the part of the second reinforcing plate connecting flange 5342 connected to the rear reinforcing plate section 533 of the horizontal tie rod bracket is connected and cooperated with the rear plate 52 of the horizontal tie rod bracket.

[0063] In a further embodiment of this application, the rear plate 52 of the horizontal tie rod bracket is provided with a rearwardly extending bracket rear plate connecting plate segment 523. The bracket rear plate connecting plate segment 523 is connected and engaged with the lower wall surface of the longitudinal beam 1. The bracket rear plate connecting plate segment 523 is vertically overlapped and connected to the second reinforcing plate connecting flange 5342, thereby forming a multi-layer structure at the bracket rear plate connecting plate segment 523, which helps to improve the local strength at the joint between the horizontal tie rod bracket 5 and the longitudinal beam 1 and reduce the risk of cracking at the joint between the horizontal tie rod bracket 5 and the longitudinal beam 1.

[0064] The rear plate connecting segment 523 of the support frame is vertically aligned with the bottom wall of the longitudinal beam 1, and its upper surface is connected to the bottom wall of the longitudinal beam 1. (Refer to...) Figure 4 The connecting plate segment 523 of the rear plate of the bracket can overlap the connecting flange 5342 of the second reinforcing plate to increase the contact area between the rear plate 52 of the horizontal tie rod bracket and the reinforcing plate 53 of the horizontal tie rod bracket, thereby improving the structural strength of the horizontal tie rod bracket 5 in the rear region.

[0065] Therefore, in the horizontal tie rod bracket 5 of this application embodiment, the front part of the horizontal tie rod bracket 5 can be connected to the first reinforcing plate connecting flange 5341 through the bracket front plate connecting plate segment 513, thereby improving the structural strength of the horizontal tie rod bracket 5 in the front region; the rear part of the horizontal tie rod bracket 5 can be connected to the second reinforcing plate connecting flange 5342 through the bracket rear plate connecting plate segment 523, thereby improving the structural strength of the horizontal tie rod bracket 5 in the rear region. At the same time, it can also increase the contact area between the horizontal tie rod bracket 5 and the longitudinal beam 1, thereby improving the connection strength between the horizontal tie rod bracket 5 and the longitudinal beam 1.

[0066] Combination Figure 2 , Figure 5 as well as Figure 7 As shown, in some embodiments of this application, the inner plate segment 511 of the front plate of the horizontal tie rod bracket 51 is connected to the inner sidewall of the longitudinal beam 1 to increase the connection area between the front plate of the horizontal tie rod bracket 51 and the longitudinal beam 1; the inner plate segment 521 of the rear plate of the horizontal tie rod bracket 52 is connected to the inner sidewall of the longitudinal beam 1 to increase the connection area between the rear plate of the horizontal tie rod bracket 52 and the longitudinal beam 1. This further increases the connection area between the horizontal tie rod bracket 5 and the longitudinal beam 1, improving the reliability of the connection between the horizontal tie rod bracket 5 and the longitudinal beam 1.

[0067] Furthermore, the inner plate segment 511 of the front plate of the horizontal tie rod bracket and the inner plate segment 521 of the rear plate of the horizontal tie rod bracket are connected and fitted together, so that the front plate 51 and the rear plate 52 of the horizontal tie rod bracket are connected and fitted together on the inner side of the longitudinal beam 1, ensuring the enclosure effect of the front plate 51 and the rear plate 52 of the horizontal tie rod bracket on the inner side of the longitudinal beam 1 and improving the connection reliability of the front plate 51 and the rear plate 52 of the horizontal tie rod bracket.

[0068] It is understood that at least a portion of the inner plate segment 511 of the front plate of the horizontal tie rod bracket and at least a portion of the inner plate segment 521 of the rear plate of the horizontal tie rod bracket are arranged correspondingly and fitted together in the inward and outward directions to ensure the connection effect between the inner plate segment 511 of the front plate of the horizontal tie rod bracket and the inner plate segment 521 of the rear plate of the horizontal tie rod bracket. For example, an overlapping flange is formed on the inner plate segment 521 of the rear plate of the horizontal tie rod bracket, which can overlap the inner plate segment 511 of the front plate of the horizontal tie rod bracket, thereby increasing the connection and mating area between the inner plate segment 521 of the rear plate of the horizontal tie rod bracket and the inner plate segment 511 of the front plate of the horizontal tie rod bracket, which is beneficial to improving the connection strength between the front plate 51 and the rear plate 52 of the horizontal tie rod bracket.

[0069] like Figure 5 As shown, in some embodiments of this application, one of the inner plate segment 511 of the front plate of the tie rod bracket and the inner plate segment 521 of the rear plate of the tie rod bracket is provided with a third opening 55. The third opening 55 is used to fill the solder to weld the inner plate segment 511 of the front plate of the tie rod bracket and the inner plate segment 521 of the rear plate of the tie rod bracket together. Thus, the inner plate segment of the front plate of the tie rod bracket 5 and the inner plate segment 521 of the rear plate of the tie rod bracket are connected and fixed by filler welding, thereby improving the local connection strength between the inner plate segment 511 of the front plate of the tie rod bracket and the inner plate segment 521 of the rear plate of the tie rod bracket. This helps to improve the durability and fatigue performance of the tie rod bracket 5, and the operation is simple and the connection reliability is high.

[0070] Understandably, the third opening 55 is located in the Y-direction opposite section of the inner plate segment 511 of the front plate of the cross brace bracket and the inner plate segment 521 of the rear plate of the cross brace bracket, and the third opening 55 is formed on the inner section structure. That is, when part of the inner plate segment 511 of the front plate of the cross brace bracket overlaps the inner side of the inner plate segment 521 of the rear plate of the cross brace bracket, the third opening 55 is located on the inner plate segment 511 of the front plate of the cross brace bracket; when part of the inner plate segment 521 of the rear plate of the cross brace bracket overlaps the inner side of the inner plate segment 511 of the front plate of the cross brace bracket, the third opening 55 is located on the inner plate segment 521 of the rear plate of the cross brace bracket. This allows the third opening 55 to be fully exposed inwards, reserving sufficient operating space inside the cross brace bracket 5 to facilitate welding operations by the operator.

[0071] In some embodiments of this application, at least one of the inner plate segment 511 of the front plate of the cross tie rod bracket and the inner plate segment 521 of the rear plate of the cross tie rod bracket is provided with a mounting hole 56, and the mounting hole 56 is disposed opposite to the inner sidewall of the longitudinal beam 1 and is used for the installation structure to pass through.

[0072] The mounting structure can be configured as a mounting sleeve, which can be used for devices near the tie rod bracket 5 in the frame assembly 100, such as steering gear, steering rocker arm, etc.

[0073] Specifically, the inner plate section 511 of the front plate of the horizontal tie rod bracket and the inner plate section 521 of the rear plate of the horizontal tie rod bracket can be arranged at a position opposite to the inner side wall of the longitudinal beam 1, so as to increase the connection and mating area between the inner plate section 511 of the front plate of the horizontal tie rod bracket, the inner plate section 521 of the rear plate of the horizontal tie rod bracket and the longitudinal beam 1, thereby further improving the connection strength between the horizontal tie rod bracket 5 and the longitudinal beam 1.

[0074] It is understandable that, taking the inner plate section 521 of the rear plate of the horizontal tie rod bracket as an example, when there is a risk of interference between the inner plate section 521 of the rear plate of the horizontal tie rod bracket and the installation structure set at the longitudinal beam 1, the installation structure can be avoided by opening the installation hole 56 on the inner plate section 521 of the rear plate of the horizontal tie rod bracket, so that the installation structure (such as: installation sleeve) can pass through the installation hole 56 and connect and cooperate with the longitudinal beam 1.

[0075] Reference Figure 4 and Figure 5 As shown, in some embodiments of this application, a portion of the main reinforcing plate segment 531 of the cross tie rod bracket is disposed opposite to the outer side wall of the longitudinal beam 1 and is provided with a clearance hole 5311. The clearance hole 5311 is used to avoid the mounting structure provided on the longitudinal beam 1. The mounting structure can be constructed as the aforementioned mounting sleeve, so as to connect the steering gear to the longitudinal beam 1 through the mounting sleeve.

[0076] It is understandable that the clearance hole 5311 is set on the plate section area corresponding to the outer side wall of the main reinforcing plate section 531 of the horizontal tie rod bracket and the longitudinal beam 1, so as to prevent interference between the main reinforcing plate section 531 of the horizontal tie rod bracket and the installation structure. The clearance hole 5311 exposes the position where the installation structure and the longitudinal beam 1 meet, and can avoid the need for the installation sleeve to pass through multiple layers of plates, thus reducing the installation difficulty of the installation sleeve.

[0077] Meanwhile, the area of ​​the plate segment that corresponds to the outer side wall of the longitudinal beam 1 in the main reinforcing plate segment 531 of the horizontal tie rod bracket is relatively large, which can further improve the connection strength between the reinforcing plate 53 of the horizontal tie rod bracket and the longitudinal beam 1.

[0078] In a further embodiment of this application, the aperture of the clearance hole 5311 is larger than the outer diameter of the mounting sleeve, so that the clearance hole 5311 can form a clearance area of ​​a certain size on the circumferential outer side of the mounting sleeve, so as to avoid the longitudinal beam 1 at the mating point between the outer wall and the mounting sleeve. In addition, the clearance hole 5311 can also reserve space for the clearance weld on the circumferential outer side of the sleeve.

[0079] Understandably, when welding equipment needs to perform welding operations from the outside of the cross tie rod bracket reinforcing plate 53, the clearance hole 5311 can also allow the welding equipment to pass through, so as to reserve operating space and allow the welding equipment to connect and fix the mounting sleeve to the longitudinal beam 1.

[0080] In some embodiments of this application, the main reinforcing plate segment 531 of the horizontal tie rod support protrudes towards the outer side of the longitudinal beam 1, thereby creating a clearance space between the main reinforcing plate segment 531 and the outer side of the longitudinal beam 1. This facilitates the welding and fixing of the mounting sleeve to the longitudinal beam 1 and avoids the need for the mounting sleeve to pass through multiple layers of plates during installation with the longitudinal beam 1, reducing the difficulty of connecting the mounting sleeve to the longitudinal beam 1. Simultaneously, the protruding structure further enhances the structural strength of the main reinforcing plate segment 531 of the horizontal tie rod support.

[0081] It should be noted that in the cross brace 5 of this application embodiment, weight reduction holes can be provided in the front plate 51, the rear plate 52, and the reinforcing plate 53 of the cross brace to achieve a lightweight design. The preferred location for the weight reduction holes is in the area where the load is relatively small.

[0082] The tie rod bracket 5 according to the embodiments of this application has at least the following advantages over the prior art:

[0083] (1) The horizontal tie rod bracket 5 has high structural strength, which enables it to meet the requirements of durability and lateral stiffness. Furthermore, the durability and fatigue performance of the horizontal tie rod bracket 5 can be further improved by the connection method of local plug welding.

[0084] (2) The tie rod bracket 5 can be connected and cooperated with the wall of the longitudinal beam 1 from multiple directions (such as: inside and outside direction, up and down direction), thereby improving the connection reliability between the tie rod bracket 5 and the longitudinal beam 1, thus dispersing the load generated by the road excitation to one side of the longitudinal beam 1 through the tie rod bracket 5, which helps to improve the driving comfort of the whole vehicle.

[0085] (3) The cross tie rod support reinforcement plate 53 has a structure that protrudes on the outer side of the side away from the longitudinal beam 1, so as to reserve space for welding the installation sleeve, making it easy to weld the installation sleeve to the longitudinal beam 1, and avoiding the problem of needing to pass through multiple layers of plates for the installation sleeve in terms of process.

[0086] The frame assembly 100 according to the embodiment of this application includes the aforementioned tie rod bracket 5. The tie rod bracket 5 has good fatigue durability and lateral stiffness, which can ensure the safety and comfort of the whole vehicle.

[0087] It should be noted that the chassis assembly 100 also includes a front axle, steering gear, steering rocker arm, and a second crossbeam 22 located in front of the tie rod bracket 5, which limits the space available for the tie rod bracket 5. In this application, the tie rod bracket 5 can be arranged within a limited space and has good durability and lateral stiffness, thus meeting the design requirement of the chassis assembly 100 to install a tie rod in the front section of the longitudinal beam 1.

[0088] According to an embodiment of this application, the vehicle includes the aforementioned frame assembly 100.

[0089] The advantages of the vehicle compared to the prior art are the same as those of the frame assembly 100 with the aforementioned tie rod bracket 5, and will not be repeated here.

[0090] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
