Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, and more specifically, relates to a rear suspension tie rod mounting assembly and a vehicle. Background Technology

[0002] The rear suspension tie rod is mounted on the rear subframe. When the vehicle is traveling on severely bumpy roads or cornering, it will experience body roll and torsion. At this time, the rear suspension tie rod intervenes to generate anti-roll drag and suppress body roll.

[0003] The strength of the rear suspension tie rod mounting points directly affects the connection strength of the rear suspension tie rod, and consequently, the overall strength of the rear subframe. In existing technologies, the mounting structure of the rear suspension tie rod is relatively weak. Taking the longitudinal tie rod mounting structure as an example, it consists of a longitudinal beam assembly and a tie rod mounting plate. The tie rod mounting plate is welded to the longitudinal beam assembly, resulting in weak connection strength and rigidity. Under severe bumpy road conditions or sharp turns, the tie rod mounting structure is prone to structural deformation after being subjected to impact, leading to low vehicle driving safety.

[0061] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0062] It should be noted that in this embodiment, the terms "front", "rear", "inner", "outer", "upper", and "lower" indicate the orientation or positional relationship based on the vehicle's own orientation. Specifically, the front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "upper", the bottom of the vehicle represents "lower", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the outside of the driver's cab.

[0063] In addition, the front-rear direction of the vehicle body defined in the embodiments of the present invention refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body defined refers to the up-down direction of the vehicle's forward direction during driving.

[0064] Please refer to the following: Figure 1 , Figure 2 , Figure 10 and Figure 12 The present invention will now describe the vehicle rear suspension tie rod mounting assembly. The vehicle rear suspension tie rod mounting assembly includes a front crossbeam 1, a rear crossbeam 2, two sets of longitudinal beams 3, two sets of longitudinal connecting structures 4, two sets of longitudinal tie rod mounting brackets 5, and a transverse tie rod mounting bracket 6. The rear crossbeam 2 is located behind the front crossbeam 1; the two sets of longitudinal beams 3 are spaced apart along the left-right direction of the vehicle body; one set of longitudinal beams 3 connects to the left end of the front crossbeam 1 and the left end of the rear crossbeam 2, and the other set of longitudinal beams 3 connects to the right end of the front crossbeam 1 and the right end of the rear crossbeam 2; the front crossbeam 1, the rear crossbeam 2, and the two sets of longitudinal beams 3 form a rectangular frame.

[0065] Two sets of longitudinal connecting structures 4 are distributed at intervals along the left and right direction of the vehicle body, and are located between the front crossbeam 1, the rear crossbeam 2 and the two sets of longitudinal beams 3 respectively; the two sets of longitudinal connecting structures 4 correspond one-to-one with the two sets of longitudinal beams 3, and the outer edge of the longitudinal connecting structure 4 is connected to the inner side of the longitudinal beam 3, the front end of the longitudinal connecting structure 4 is connected to the front crossbeam 1, and the rear end of the longitudinal connecting structure 4 is connected to the rear crossbeam 2.

[0066] The longitudinal tie rod mounting bracket 5 is used to install the rear suspension longitudinal tie rod 100. Two sets of longitudinal tie rod mounting brackets 5 are respectively installed on the front crossbeam 1, and correspond one-to-one with the two sets of longitudinal connecting structures 4; the longitudinal tie rod mounting bracket 5 is located below the front end of the corresponding longitudinal connecting structure 4. The transverse tie rod mounting bracket 6 is used to install the rear suspension transverse tie rod 200. The transverse tie rod mounting bracket 6 is installed on the rear crossbeam 2, and is located below the rear end of one set of longitudinal connecting structures 4.

[0067] There are two rear suspension longitudinal tie rods 100, with one end of each tie rod mounted on the rear axle assembly and the other end hinged to the longitudinal tie rod mounting bracket 5. There is one rear suspension transverse tie rod 200, with one end also fixed to the rear axle assembly and the other end hinged to the transverse tie rod mounting bracket 6.

[0068] It should be noted that the rear frame of a vehicle generally includes a front crossbeam 1, a rear crossbeam 2, and two longitudinal beams 3 on the left and right. In this embodiment, a rectangular frame is formed by the front crossbeam 1, the rear crossbeam 2, and the two longitudinal beams 3. Two sets of longitudinal connecting structures 4 are added within the rectangular frame. The longitudinal connecting structures 4 are connected to the rectangular frame along the front-rear direction and the left-right direction of the vehicle body, respectively, to improve the overall strength of the rectangular frame and prevent its deformation.

[0069] Compared with the prior art, the vehicle rear suspension tie rod mounting assembly provided by the present invention has the lateral tie rod mounting bracket 6 and the longitudinal tie rod mounting bracket 5 respectively set at the corner positions of the rectangular frame and respectively corresponding to the longitudinal connecting structure 4 vertically. The rectangular frame and the two sets of longitudinal connecting structures 4 can improve the overall strength and rigidity of the rear suspension tie rod fixation, thereby improving the vehicle driving safety performance.

[0070] In some embodiments, the aforementioned vehicle rear suspension tie rod mounting assembly can be adopted as follows: Figure 3 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 3 , Figure 4 and Figure 5 The front crossbeam 1 has a front crossbeam cavity 14 extending along the left-right direction of the vehicle body; the rear crossbeam 2 has a rear crossbeam cavity 25 extending along the left-right direction of the vehicle body; a front reinforcing cavity 44 is formed between the front end of the longitudinal connecting structure 4 and the front crossbeam 1, and a rear reinforcing cavity 45 is formed between the rear end of the longitudinal connecting structure 4 and the rear crossbeam 2; a transverse tie rod mounting bracket 6 is formed between the transverse tie rod mounting cavity 63 and the rear crossbeam 2. The rear reinforcing cavity 45, the rear crossbeam cavity 25, and the transverse tie rod mounting cavity 63 are distributed sequentially from top to bottom; the front reinforcing cavity 44 is located above and behind the front crossbeam cavity 14.

[0071] It should be noted that both the front crossbeam 1 and the rear crossbeam 2 are tubular beams. Specifically, the front crossbeam 1 includes an upper front crossbeam plate 11 and a lower front crossbeam plate 12. The two side plates of the upper front crossbeam plate 11 are folded downwards, and the two side plates of the lower front crossbeam plate 12 are flipped upwards. The two side plates of the upper front crossbeam plate 11 and the two side plates of the lower front crossbeam plate 12 are welded to each other to form a rectangular front crossbeam cavity 14.

[0072] Specifically, the rear crossbeam 2 includes an upper rear crossbeam plate 23 and a lower rear crossbeam plate 24. The two side plates of the upper rear crossbeam plate 23 are folded downwards, and the two side plates of the lower rear crossbeam plate 24 are flipped upwards. The two side plates of the upper rear crossbeam plate 23 and the two side plates of the lower rear crossbeam plate 24 are welded to each other to form a rectangular rear crossbeam cavity 25.

[0073] A front reinforcing cavity 44 is formed between the front end of the longitudinal connecting structure 4 and the front crossbeam 1. Specifically, the longitudinal section of the front reinforcing cavity 44 is triangular. The front crossbeam 1 is inclined relative to the front-rear direction of the vehicle body and is inclined upward from front to rear. The front reinforcing cavity 44 is located above and behind the front crossbeam cavity 14, and the two are in a structure that is obliquely superimposed from front to rear.

[0074] A rear reinforcing cavity 45 is formed between the rear end of the longitudinal connecting structure 4 and the rear crossbeam 2. Specifically, the rear reinforcing cavity 45 is a rectangular cavity. The rear reinforcing cavity 45, the rear crossbeam cavity 25, and the transverse tie rod mounting cavity 63 form an upper and lower superimposed structure.

[0075] Since the rear suspension longitudinal tie rod 100 mainly bears forces from the front-to-back direction of the vehicle body, the front reinforcing cavity 44 and the front crossbeam cavity 14 are stacked at an angle from front to back, which can increase the force transmission path in the front-to-back direction of the vehicle body, thereby improving the fixing strength of the longitudinal tie rod mounting bracket 5 in the front-to-back direction of the vehicle body. The rear suspension longitudinal tie rod 100 mainly bears forces from the left-to-right direction of the vehicle body, so the rear reinforcing cavity 45 and the rear crossbeam cavity 25 do not need to be stacked in the front-to-back direction of the vehicle body.

[0076] In addition, cavity structures are set at the front and rear ends of the longitudinal connection structure 4, which can absorb vibration and deformation energy and increase the overall strength, achieving a high-strength load-bearing effect.

[0077] In some embodiments, the longitudinal connection structure 4 described above can be as follows: Figure 3 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 3 , Figure 4 and Figure 5 The longitudinal connection structure 4 includes a longitudinal connection plate 41, a longitudinal front reinforcing plate 42, and a longitudinal rear reinforcing plate 43.

[0078] The front end of the longitudinal connecting plate 41 is connected to the upper side of the front crossbeam 1, and the rear end is connected to the front side of the rear crossbeam 2; the longitudinal front reinforcing plate 42 is located below the longitudinal connecting plate 41, with its front end connected to the rear side of the front crossbeam 1 and its rear end connected to the longitudinal connecting plate 41; the longitudinal rear reinforcing plate 43 is located above the longitudinal connecting plate 41, with its front end connected to the longitudinal connecting plate 41 and its rear end connected to the upper side of the rear crossbeam 2.

[0079] Among them, a front reinforcing cavity 44 is formed between the longitudinal connecting plate 41, the longitudinal front reinforcing plate 42 and the rear side of the front crossbeam 1; a rear reinforcing cavity 45 is formed between the longitudinal connecting plate 41, the longitudinal rear reinforcing plate 43 and the upper side of the rear crossbeam 2.

[0080] It should be noted that the longitudinal connecting plate 41, the longitudinal front reinforcing plate 42, and the longitudinal rear reinforcing plate 43 are all roughly L-shaped plate structures. The front end of the horizontal plate surface of the longitudinal connecting plate 41 is welded to the upper side of the front crossbeam 1, and the rear end of the longitudinal connecting plate 41 is folded downward and connected to the front side of the rear crossbeam 2. The rear half of the longitudinal front reinforcing plate 42 is welded to the longitudinal connecting plate 41, and the front half is folded downward at an angle and welded to the rear side of the front crossbeam 1. The front half of the longitudinal rear reinforcing plate 43 is welded to the longitudinal connecting plate 41, and the rear half is folded downward and backward and welded to the upper side of the rear crossbeam 2.

[0081] Preferably, in order to reduce the overall weight of the longitudinal connecting structure 4, the rear end edge of the longitudinal front reinforcing plate 42 is located in front of the front end edge of the longitudinal rear reinforcing plate 43, that is, the longitudinal front reinforcing plate 42 and the longitudinal rear reinforcing plate 43 do not overlap.

[0082] The longitudinal connection structure 4 includes a longitudinal connection plate 41, a longitudinal front reinforcing plate 42, and a longitudinal rear reinforcing plate 43. It can not only ensure that a front reinforcing cavity 44 is formed between the longitudinal connection structure 41 and the front crossbeam 1, and a rear reinforcing cavity 45 is formed between the longitudinal connection structure 4 and the rear crossbeam 2, but also improve the overall strength of the longitudinal connection structure 4 and facilitate the fabrication and assembly of the longitudinal front reinforcing plate 42 and the longitudinal rear reinforcing plate 43.

[0083] In some embodiments, the longitudinal beam 3 can be adopted as follows: Figure 1 The structure shown is described in the following document. Figure 1 The longitudinal beam 3 is an arched structure with the middle part arching upwards; the front crossbeam 1 is located at the front end of the arched part of the longitudinal beam 3, and the rear crossbeam 2 is located at the rear end of the arched part of the longitudinal beam 3.

[0084] As the main longitudinal force transmission channel of the rear suspension tie rod mounting assembly of the vehicle, the structural strength of the longitudinal beam 3 has a critical impact on the overall structure. By designing the longitudinal beam 3 as an arched structure, and relying on the high strength and load-bearing characteristics of the arched structure, the strength and stiffness of the rear suspension tie rod mounting assembly of the vehicle are further increased, thereby improving the installation stability of the rear suspension tie rod.

[0085] Specifically, longitudinal beam 3 is also a tubular beam, including an inner longitudinal beam plate 31 and an outer longitudinal beam plate 32, such as... Figure 11 and Figure 13 As shown. The upper and lower side plates of the inner plate 31 of the longitudinal beam are folded backward, and the upper and lower side plates of the outer plate 32 of the longitudinal beam are folded forward. The upper and lower side plates of the inner plate 31 and the upper and lower side plates of the outer plate 32 of the longitudinal beam are welded to each other to form the longitudinal beam cavity 34.

[0086] In some embodiments, the aforementioned transverse tie rod mounting bracket 6 can be adopted as follows: Figure 9 The structure shown is described in the following document. Figure 9 The transverse tie rod mounting bracket 6 is located at one end of the rear crossbeam 2 and extends outward to connect with one of the longitudinal beams 3.

[0087] The transverse tie rod mounting bracket 6 is not only connected to the rear crossbeam 2, but also to one of the longitudinal beams 3. With the help of the longitudinal beams 3, the fixing strength of the transverse tie rod mounting bracket 6 can be increased, thereby improving the installation strength of the rear suspended transverse tie rod 200.

[0088] Preferably, please refer to Figure 7 , Figure 8 and Figure 9 Based on the above embodiments, the transverse tie rod mounting bracket 6 includes a transverse tie rod mounting front plate 61 and a transverse tie rod mounting rear plate 62. The upper edge of the transverse tie rod mounting front plate 61 is connected to the front side of the rear crossbeam 2; the upper edge of the transverse tie rod mounting rear plate 62 is connected to the rear side of the rear crossbeam 2; wherein, a transverse tie rod mounting cavity 63 is formed between the transverse tie rod mounting front plate 61, the transverse tie rod mounting rear plate 62 and the lower side of the rear crossbeam 2.

[0089] The front mounting plate 61 and the rear mounting plate 62 of the transverse tie rod can be flat or L-shaped (i.e., the lower end of the front mounting plate 61 folds backward and the lower end of the rear mounting plate 62 folds forward, with the folded lower ends of the two plates meeting). Figure 5 (As shown).

[0090] The transverse tie rod mounting bracket 6 consists of a front transverse tie rod mounting plate 61 and a rear transverse tie rod mounting plate 62. Its structure is simple, easy to manufacture, and facilitates welding and assembly with the front and rear sides of the rear crossbeam 2.

[0091] Preferably, in order to avoid the rear suspension transverse tie rod 200, an avoidance hole 65 is also provided on the lower side of the transverse tie rod mounting bracket 6.

[0092] Preferably, please refer to Figure 7 and Figure 9Based on the above embodiment, the upper edge of the front plate 61 for mounting the transverse tie rod and the upper edge of the rear plate 62 for mounting the transverse tie rod are respectively provided with clearance notches 64. The clearance notches 64 include a first vertical connecting edge 641, a transverse connecting edge 642, and a second vertical connecting edge 643 connected sequentially from the inside to the outside. The first vertical connecting edge 641 is connected to the inner side of the longitudinal beam 3, the transverse connecting edge 642 is connected to the lower side of the longitudinal beam 3, and the second vertical connecting edge 643 is connected to the outer side of the longitudinal beam 3. In addition, the upper edge of the end of the rear crossbeam 2 is connected to the upper side of the longitudinal beam 3.

[0093] A clearance notch 64 is provided on the upper edge of the front plate 61 and the upper edge of the rear plate 62 of the transverse tie rod installation. Through the three sides of the clearance notch 64 and the upper edge of the end of the rear crossbeam 2, a four-sided covering structure is formed with the longitudinal beam 3, which further enhances the fixing strength of the transverse tie rod installation bracket 6 and improves the safety performance.

[0094] In some embodiments, the aforementioned rear crossbeam 2 can be adopted as follows: Figure 6 The structure shown is described in the following document. Figure 6 The rear crossbeam 2 includes a main body 21 and a raised portion 22. One end of the main body 21 is connected to the inner side of one of the longitudinal beams 3; the raised portion 22 is formed at the other end of the main body 21 and protrudes upward from the main body 21; the end of the raised portion 22 is connected to the inner side of another set of longitudinal beams 3; a weight-reducing hole 221 is provided on the lower side of the raised portion 22; wherein, the transverse tie rod mounting bracket 6 is connected to the lower part of the raised portion 22.

[0095] The rear crossbeam 2 includes a main body 21 and an upwardly protruding upturned part 22. In other words, the rear crossbeam 2 has a stepped, gradually rising structure. The transverse tie rod mounting bracket 6 is connected to the lower part of the upturned part 22 to raise the fixed position of the transverse tie rod mounting bracket 6 and avoid interference between the transverse tie rod mounting bracket 6 and the rear suspended transverse tie rod 200.

[0096] In addition, a weight-reducing hole 221 is provided on the lower side of the raised part 22 to realize the open structure of the cavity at the docking position, which achieves overall weight reduction while meeting the requirements of high-strength structural connection.

[0097] Preferably, the upper edge of the transverse tie rod mounting bracket 6 is also a stepped, gradually ascending structure, for good welding with the rear crossbeam 2.

[0098] In some embodiments, the aforementioned vehicle rear suspension tie rod mounting assembly may also employ, for example... Figures 10 to 13 The structure shown is described in the following document. Figures 10 to 13 The lower side of the front crossbeam 1 is provided with a longitudinal tie rod reinforcing plate 51 (e.g., Figure 13As shown), the longitudinal tie rod reinforcing plate 51 is also connected to the longitudinal tie rod mounting bracket 5; in addition, the lower cavity wall of the front crossbeam cavity 14 is provided with a front crossbeam reinforcing plate 13 (as shown). Figure 13 As shown, the front crossbeam reinforcing plate 13 and the longitudinal tie rod reinforcing plate 51 are vertically aligned.

[0099] The longitudinal tie rod reinforcing plate 51 and the front crossbeam reinforcing plate 13 are used to increase the fixing strength between the longitudinal tie rod mounting bracket 5 and the front crossbeam 1, thereby improving the installation stability of the longitudinal tie rod mounting bracket 5.
