Description

[0002] The rear suspension tie rod is installed on the rear subframe. When the vehicle is driving on a bumpy or curved road, it will produce roll and torsion. At this time, the rear suspension tie rod intervenes to generate anti-roll resistance and suppress the body roll.

[0003] The strength of the rear suspension tie rod mounting point directly affects the connection strength of the rear suspension tie rod, and further affects the overall strength of the rear subframe.

[0064] Please also read Figure 1 , Figure 2 , Fig.10 and Fig.12 Now, the vehicle rear suspension tie rod installation assembly provided by the present invention is described. The vehicle rear suspension tie rod installation assembly comprises a front cross beam 1, a rear cross beam 2, two sets of longitudinal beams 3, two sets of longitudinal connection structures 4, two sets of longitudinal tie rod installation brackets 5 and a transverse tie rod installation bracket 6. The rear cross beam 2 is located behind the front cross beam 1; the two sets of longitudinal beams 3 are spaced apart along the left and right directions of the vehicle body; one set of longitudinal beams 3 is connected to the left end of the front cross beam 1 and the left end of the rear cross beam 2, and the other set of longitudinal beams 3 is connected to the right end of the front cross beam 1 and the right end of the rear cross beam 2; the front cross beam 1, the rear cross beam 2 and the two sets of longitudinal beams 3 form a rectangular frame.

[0065] The two groups of longitudinal connecting structures 4 are spaced apart along the left-right direction of the vehicle body, and are respectively located between the front cross beam 1, the rear cross beam 2 and the two groups of longitudinal beams 3; the two groups of longitudinal connecting structures 4 correspond to the two groups of longitudinal beams 3 one by one, and the outer edges of the longitudinal connecting structures 4 are connected to the inner sides of the longitudinal beams 3, the front ends of the longitudinal connecting structures 4 are connected to the front cross beam 1, and the rear ends of the longitudinal connecting structures 4 are connected to the rear cross beam 2.

[0066] The longitudinal tie rod mounting bracket 5 is used to install the rear suspension longitudinal tie rod 100. Two groups of longitudinal tie rod mounting brackets 5 are respectively arranged on the front cross beam 1, and correspond to the two groups of longitudinal connection structures 4 one by one; the longitudinal tie rod mounting bracket 5 is located below the front end of the corresponding longitudinal connection 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 arranged on the rear cross beam 2, and is located below the rear end of one group of longitudinal connection structures 4.

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

[0068] It should be noted that the rear frame of the vehicle generally includes a front cross beam 1, a rear cross beam 2 and two left and right longitudinal beams 3. This embodiment uses a rectangular frame formed by the front cross beam 1, the rear cross beam 2 and the two longitudinal beams 3, and adds two sets of longitudinal connection structures 4 in the rectangular frame, and the longitudinal connection structures 4 are respectively connected to the rectangular frame along the front-rear direction of the vehicle body and the left-right direction of the vehicle body 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 installation assembly provided by the present invention has a transverse tie rod installation bracket 6 and a longitudinal tie rod installation bracket 5 respectively arranged at the corner points of the rectangular frame, and respectively corresponding to the longitudinal connecting structure 4 up and down. The rectangular frame and the two groups of longitudinal connecting structures 4 can improve the overall strength and rigidity of the rear suspension tie rod fixation, thereby improving the safety performance of vehicle driving.

[0070] In some embodiments, the vehicle rear suspension tie rod installation assembly can be used as follows: Figure 3 , Figure 4 and Figure 5 The structure shown, see Figure 3 , Figure 4 and Figure 5 The front cross beam 1 has a front cross beam cavity 14 that penetrates along the left-right direction of the vehicle body; the rear cross beam 2 has a rear cross beam cavity 25 that penetrates along the left-right direction of the vehicle body; a front reinforcement cavity 44 is formed between the front end of the longitudinal connection structure 4 and the front cross beam 1, and a rear reinforcement cavity 45 is formed between the rear end of the longitudinal connection structure 4 and the rear cross beam 2; a transverse tie rod installation cavity 63 is formed between the transverse tie rod installation bracket 6 and the rear cross beam 2. Among them, the rear reinforcement cavity 45, the rear cross beam cavity 25 and the transverse tie rod installation cavity 63 are distributed in sequence from top to bottom; the front reinforcement cavity 44 is located at the rear and upper part of the front cross beam cavity 14.

[0071] It should be noted that the front cross beam 1 and the rear cross beam 2 are both tubular beams. Specifically, the front cross beam 1 includes a front cross beam upper plate 11 and a front cross beam lower plate 12, the two side plate surfaces of the front cross beam upper plate 11 are folded downward, and the two side plate surfaces of the front cross beam lower plate 12 are turned upward, and the two side plate surfaces of the front cross beam upper plate 11 and the two side plate surfaces of the front cross beam lower plate 12 are respectively welded to form a rectangular front cross beam cavity 14.

[0072] Specifically, the rear cross beam 2 includes a rear cross beam upper plate 23 and a rear cross beam lower plate 24. The two side plate surfaces of the rear cross beam upper plate 23 are folded downward, and the two side plate surfaces of the rear cross beam lower plate 24 are flipped upward. The two side plate surfaces of the rear cross beam upper plate 23 and the two side plate surfaces of the rear cross beam lower plate 24 are respectively welded correspondingly, thereby forming a rectangular rear cross beam cavity 25.

[0073] A front reinforcement cavity 44 is formed between the front end of the longitudinal connection structure 4 and the front cross beam 1. Specifically, the longitudinal section of the front reinforcement cavity 44 is triangular. The front cross beam 1 is inclined relative to the front and rear directions of the vehicle body and is inclined upward from front to rear. The front reinforcement cavity 44 is located above and behind the front cross beam cavity 14, and the two are in a structure of oblique superposition from front to rear.

[0074] A rear reinforcement cavity 45 is formed between the rear end of the longitudinal connection structure 4 and the rear cross beam 2. Specifically, the rear reinforcement cavity 45 is a rectangular cavity. The rear reinforcement cavity 45, the rear cross beam cavity 25 and the transverse tie rod installation cavity 63 form a structure stacked up and down.

[0075] Since the rear suspension longitudinal tie rod 100 mainly bears the force from the front-to-back direction of the vehicle body, the front reinforcement cavity 44 and the front cross beam cavity 14 are superimposed obliquely from front to back, which can also increase the force transmission path along the front-to-back direction of the vehicle body, thereby improving the fixing strength of the longitudinal tie rod mounting bracket 5 along the front-to-back direction of the vehicle body. The rear suspension longitudinal tie rod 100 mainly bears the force from the left-to-right direction of the vehicle body, so the rear reinforcement cavity 45 and the rear cross beam cavity 25 do not need to be superimposed along the front-to-back direction of the vehicle body.

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

[0077] In some embodiments, the longitudinal connection structure 4 may be formed as follows: Figure 3 , Figure 4 and Figure 5 The structure shown, see Figure 3 , Figure 4 and Figure 5 The longitudinal connection structure 4 includes a longitudinal connection plate 41 , a longitudinal front reinforcement plate 42 and a longitudinal rear reinforcement plate 43 .

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

[0079] A front reinforcement cavity 44 is formed between the longitudinal connecting plate 41 , the longitudinal front reinforcing plate 42 and the rear side surface of the front cross beam 1 ; a rear reinforcement cavity 45 is formed between the longitudinal connecting plate 41 , the longitudinal rear reinforcing plate 43 and the upper side surface of the rear cross beam 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 cross beam 1, and the rear end of the longitudinal connecting plate 41 is folded downward and connected to the front side of the rear cross beam 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 cross beam 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 cross beam 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 connecting structure 4 includes a longitudinal connecting plate 41, a longitudinal front reinforcing plate 42 and a longitudinal rear reinforcing plate 43, which can not only ensure the formation of a front reinforcing cavity 44 between the front cross beam 1 and a rear reinforcing cavity 45 between the rear cross beam 2, but also improve the overall strength of the longitudinal connecting structure 4, and facilitate the manufacture and assembly of the longitudinal front reinforcing plate 42 and the longitudinal rear reinforcing plate 43.

[0083] In some embodiments, the longitudinal beam 3 may be Figure 1 The structure shown, see Figure 1 The longitudinal beam 3 is an arched structure with an upward arched middle portion; the front cross beam 1 is arranged at the front end of the arched portion of the longitudinal beam 3, and the rear cross beam 2 is arranged at the rear end of the arched portion of the longitudinal beam 3.

[0084] The longitudinal beam 3 is the main longitudinal force transmission channel of the rear suspension tie rod installation assembly of the vehicle, and its structural strength has a key impact on the overall structure. The longitudinal beam 3 is designed as an arch structure, relying on the high-strength load-bearing characteristics of the arch structure, to further increase the strength and rigidity of the rear suspension tie rod installation assembly of the vehicle, and improve the installation stability of the rear suspension tie rod.

[0085] Specifically, the longitudinal beam 3 is also a tubular beam, including a longitudinal beam inner plate 31 and a longitudinal beam outer plate 32. Fig.11 and Fig.13 The upper and lower side panels of the longitudinal beam inner panel 31 are folded backward, and the upper and lower side panels of the longitudinal beam outer panel 32 are folded forward. The upper and lower side panels of the longitudinal beam inner panel 31 and the upper and lower side panels of the longitudinal beam outer panel 32 are welded respectively to form a longitudinal beam cavity 34.

[0086] In some embodiments, the lateral tie rod mounting bracket 6 may be configured as follows: Fig. 9 The structure shown, see Fig. 9 The transverse tie rod mounting bracket 6 is arranged at one end of the rear cross beam 2 and extends outward to be connected with one set of longitudinal beams 3 .

[0087] The transverse tie rod mounting bracket 6 is not only connected to the rear cross beam 2, but also connected to one set of longitudinal beams 3. The longitudinal beams 3 can be used to increase the fixing strength of the transverse tie rod mounting bracket 6, thereby improving the installation strength of the rear suspension transverse tie rod 200.

[0088] Preferably, see Figure 7 , Figure 8 and Fig. 9 On the basis of the above embodiment, the transverse tie rod mounting bracket 6 comprises 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 cross beam 2; the upper edge of the transverse tie rod mounting rear plate 62 is connected to the rear side of the rear cross beam 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 cross beam 2.

[0089] The transverse tie rod installation front plate 61 and the transverse tie rod installation rear plate 62 can be a flat plate structure or an L-shaped plate structure (i.e., the lower end of the transverse tie rod installation front plate 61 is folded backward, and the lower end of the transverse tie rod installation rear plate 62 is folded forward, and the folded parts of the lower ends of the two plates are connected, such as Figure 5 shown).

[0090] The transverse tie rod mounting bracket 6 is composed of a transverse tie rod mounting front plate 61 and a transverse tie rod mounting rear plate 62, and has a simple structure, is easy to manufacture, and is convenient to be welded and assembled with the front side and the rear side of the rear cross beam 2.

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

[0092] Preferably, see Figure 7 and Fig. 9On the basis of the above embodiment, the upper edge of the transverse tie rod installation front plate 61 and the upper edge of the transverse tie rod installation rear plate 62 are respectively provided with an avoidance notch 64, and the avoidance notch 64 includes a first vertical connection edge 641, a transverse connection edge 642, and a second vertical connection edge 643 which are sequentially connected from the inside to the outside; the first vertical connection edge 641 is connected to the inner side surface of the longitudinal beam 3, the transverse connection edge 642 is connected to the lower side surface of the longitudinal beam 3, and the second vertical connection edge 643 is connected to the outer side surface of the longitudinal beam 3. In addition, the upper edge of the end of the rear cross beam 2 is connected to the upper side surface of the longitudinal beam 3.

[0093] An avoidance gap 64 is opened at the upper edge of the transverse tie rod installation front plate 61 and the upper edge of the transverse tie rod installation rear plate 62. The three side edges of the avoidance gap 64 and the upper edge of the end of the rear cross beam 2 form a four-way covering structure with the longitudinal beam 3, further enhancing the fixing strength of the transverse tie rod installation bracket 6 and improving the safety performance.

[0094] In some embodiments, the rear cross beam 2 may be Figure 6 The structure shown, see Figure 6 The rear cross beam 2 includes a main body 21 and a raised portion 22. One end of the main body 21 is connected to the inner side surface of one set of 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 surface of the other set of longitudinal beams 3; a weight-reducing hole 221 is provided on the lower side surface of the raised portion 22; wherein the transverse tie rod mounting bracket 6 is connected to the lower part of the raised portion 22.

[0096] In addition, a weight-reducing hole 221 is provided on the lower side of the raised portion 22 to realize an open cavity structure at the docking position, thereby achieving overall weight reduction while satisfying high-strength structural connection.

[0097] Preferably, the upper edge of the transverse tie rod mounting bracket 6 is also a step-type gradually rising structure for good welding with the rear cross beam 2 .
