Description

Technical Field

[0001] This utility model relates to the technical field of automotive suspension systems, specifically to an automotive suspension equalization beam. Background Technology

[0002] The vehicle suspension equalizer beam connects the left and right wheel suspension systems or wheel assemblies, distributing the vehicle's weight and dynamic loads generated during driving evenly to each wheel. This improves the vehicle's driving stability and handling. At the same time, it can disperse concentrated stress and reduce local deformation, reduce the risk of wear on key components (such as springs and suspensions), and prevent safety hazards caused by cracks or structural failures. It is an important safety structural component of automobiles.

[0003] The existing automotive suspension balance beam has an unreasonable overall structural layout. For example, the connection parts on both sides of the axle mounting section are modeled with an I-beam-like structure. Although it has strong bending resistance, it has weak torsional resistance. Moreover, in actual use, there have been cases where the two connection parts have deformed significantly due to excessive instantaneous torsional impact, which has endangered the driving safety of the vehicle. At the same time, the existing structure also has the problem of the axle mounting section being too large and thick, which does not meet the requirements of lightweight design and has room for further optimization.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 only for explaining this utility model and are not intended to limit this utility model.

[0026] like Figures 1 to 6As shown, an embodiment of the present invention for an automotive suspension equalization beam is disclosed. The automotive suspension equalization beam includes a front airbag mounting part 1, a first connecting part 2, an axle mounting part 3, a second connecting part 4, and a rear airbag mounting part 5 connected in sequence. The first connecting part 2 and the second connecting part 4 are both U-shaped. The bottom sides of the first connecting part 2 are respectively provided with a first flange 21, and the bottom of the first connecting part 2 is provided with a first weight-reducing groove 22, and a first reinforcing rib 23 is provided in the first weight-reducing groove 22. The bottom sides of the second connecting part 4 are respectively provided with a second flange 41, and the bottom of the second connecting part 4 is provided with a second weight-reducing groove 42, and a second reinforcing rib 43 is provided in the second weight-reducing groove 42. The top of the second connecting part 4 is provided with a third reinforcing rib 44, which extends to the axle mounting part 3. The bottom of the axle mounting part 3 is provided with a third weight-reducing groove 31, and a central reinforcing rib 32 is provided in the third weight-reducing groove 31.

[0027] The automotive suspension balance beam fully considers the stress type and distribution when bearing the main load. By designing the first connecting part 2 and the second connecting part 4 into a U-shape, the bending and torsional resistance of the first connecting part 2 and the second connecting part 4 are effectively improved. By setting the first flange 21 on both sides of the bottom of the first connecting part 2 and the second flange 41 on both sides of the bottom of the second connecting part 4, the load-bearing capacity of the first connecting part 2 and the second connecting part 4 is effectively improved. By opening the first weight-reducing groove 22 at the bottom of the first connecting part 2 and setting the first reinforcing rib 23 in the first weight-reducing groove 22, opening the second weight-reducing groove 42 at the bottom of the second connecting part 4 and setting the second reinforcing rib 43 in the second weight-reducing groove 42, opening the third weight-reducing groove 31 at the bottom of the axle mounting part 3 and setting the central reinforcing rib 32 in the third weight-reducing groove 31, and setting the third reinforcing rib 44 between the top of the second connecting part 4 and the axle mounting part 3, the weight reduction purpose is achieved, meeting the requirements of lightweight design, while strengthening the structural strength of the corresponding parts and ensuring the load-bearing capacity of the automotive suspension balance beam.

[0028] For ease of description and understanding, the XYZ spatial rectangular coordinate system is defined as follows: Figure 1 As shown, in this embodiment, the first reinforcing rib 23 preferably extends along the X direction, the second reinforcing rib 43 extends along the Y direction and its two ends extend to the two side walls of the second weight-reducing groove 42 respectively, the third reinforcing rib 44 extends along the X direction and protrudes from the upper surface of the second connecting part 4 in the Z direction, and the central reinforcing rib 32 is disposed between the side wall and the top wall of the third weight-reducing groove 31.

[0029] To facilitate the installation of the front airbag, the front airbag mounting part 1 in this embodiment has a first mounting surface 11 at its top, a first nut mounting surface 12 at its bottom, and a first bolt hole 13 penetrating the first mounting surface 11 and the first nut mounting surface 12. The end of the front airbag mounting part 1 near the first mounting surface 11 is trapezoidal. By providing the first mounting surface 11 and the first nut mounting surface 12, the contact area is increased, which can effectively disperse the contact pressure, thereby reducing the impact of stress concentration at this location and improving the structural strength.

[0030] As shown in the figure, in this embodiment, the end of the front airbag mounting part 1 near the first mounting surface 11 is designed as a trapezoid. This design takes into account both dispersing contact pressure and achieving lightweight design. It can also be seen from the figure that the first bolt hole 13 is opened at one end of the first nut mounting surface 12, while the other end of the first nut mounting surface 12 is reserved with a larger contact area. This design takes into account that the opening position of the first bolt hole 13 is slightly different for different car models. Designers can flexibly open the first bolt hole 13 according to actual needs, thereby improving the applicability of the car suspension balance beam and achieving multiple uses with one piece.

[0031] To facilitate the installation of the rear airbag, the rear airbag mounting part 5 in this embodiment has a second mounting surface 51 at its top, a second nut mounting surface 52 at its bottom, and a second bolt hole 53 penetrating the second mounting surface 51 and the second nut mounting surface 52. The end of the rear airbag mounting part 5 near the second mounting surface 51 is trapezoidal. By providing the second mounting surface 51 and the second nut mounting surface 52, the contact area is increased, which can effectively disperse the contact pressure, thereby reducing the impact of stress concentration at this location and improving the structural strength.

[0032] As shown in the figure, in this embodiment, the end of the rear airbag mounting part 5 near the second assembly surface 51 is designed as a trapezoid. This design takes into account both dispersing contact pressure and achieving lightweight design. It can also be seen from the figure that the second bolt hole 53 is opened at one end of the second nut mounting surface 52, while the other end of the second nut mounting surface 52 is reserved with a larger contact area. This design takes into account that the opening position of the second bolt hole 53 is slightly different for different car models. Designers can flexibly open the second bolt hole 53 according to actual needs, thereby improving the applicability of the car suspension balance beam and achieving multiple uses with one piece.

[0033] To facilitate assembly with the vehicle axle, the axle mounting part 3 in this embodiment has a third mounting surface 33 on its top, two axle side baffles 34 spaced apart on the third mounting surface 33, a fourth mounting surface 35 on one of the axle side baffles 34, a third nut mounting surface 36 at the bottom of the axle mounting part 3, a first weight reduction hole 37, and two sets of third bolt holes 38. One set of third bolt holes 38 penetrates the third mounting surface 33 and the third nut mounting surface 36, and the other set of third bolt holes 38 penetrates the fourth mounting surface 35 and the third nut mounting surface 36. The first weight reduction hole 37 is located between the two axle side baffles 34 and connects to the third weight reduction groove 31 after penetrating the third mounting surface 33. The function of the third mounting surface 33 is to limit the position of the axle in the Z direction; the function of the axle side baffle 34 is to prevent the axle from sliding in the X direction; the fourth mounting surface 35, the third nut mounting surface 36 and the third bolt hole 38 can realize the installation of U bolts. The third mounting surface 33, the axle side baffle 34 and the U bolts cooperate to realize the fixed connection between the axle and the vehicle suspension balance beam; the design of the first weight reduction hole 37 is to reduce weight so that the vehicle suspension balance beam can further meet the requirements of lightweight design.

[0034] To facilitate the installation of the shock absorber, in this embodiment, a fourth bolt hole 24 is provided on the first connecting part 2. The first connecting part 2 near the axle mounting part 3 has a fifth mounting surface 25 and a fourth nut mounting surface 26 on its two sides respectively. The fourth bolt hole 24 penetrates the fifth mounting surface 25 and the fourth nut mounting surface 26, thereby jointly serving to connect and fix one end of the shock absorber.

[0035] The vehicle suspension equalizer beam in this embodiment also includes a thrust rod bracket mounting part 6, a jack lifting contact part 7, and a stabilizer bar mounting part 8. The thrust rod bracket mounting part 6 and the jack lifting contact part 7 are arranged side by side at the bottom of the axle mounting part 3, and the stabilizer bar mounting part 8 is located at the bottom of the second connecting part 4. By integrating the thrust rod bracket mounting part 6, the jack lifting contact part 7, and the stabilizer bar mounting part 8, the installation of the thrust rod bracket and the stabilizer bar, as well as the jacking operation, are facilitated.

[0036] The thrust rod bracket mounting part 6 in this embodiment includes two spaced mounting heads 61. The mounting head 61 has a sixth assembly surface 610 and a fifth nut mounting surface 611, as well as a fifth bolt hole 612 that passes through the sixth assembly surface 610 and the fifth nut mounting surface 611.

[0037] Specifically, one of the mounting heads 61 is connected to the axle mounting part 3 via a transition structure 62. The transition structure 62 is provided with a second weight-reducing hole 620 that communicates with the third weight-reducing groove 31. This arrangement further embodies the lightweight design concept. The other mounting head 61 is connected to the axle mounting part 3 via a connecting plate 63. The edge of the connecting plate 63 is provided with a fourth reinforcing rib 64. This arrangement ensures the support strength and structural stability of the mounting head 61.

[0038] In this embodiment, the jack lifting contact part 7 extends out of the side of the axle mounting part 3. A lifting contact plane 71 is provided at the bottom of the jack lifting contact part 7, and a fifth reinforcing rib 72 is provided between the top of the jack lifting contact part 7 and the side of the axle mounting part 3. By providing the lifting contact plane 71, the jack can easily lift the axle at this location, while the fifth reinforcing rib 72 improves the load-bearing capacity at this point, preventing parts from breaking or deforming significantly during the lifting process.

[0039] In this embodiment, the stabilizer bar mounting part 8 has a seventh mounting surface 81, two sets of sixth bolt holes 82 penetrating the seventh mounting surface 81, and a stabilizer bar mounting groove 83. The stabilizer bar mounting groove 83 is located between the two sets of sixth bolt holes 82. The stabilizer bar mounting part 8 extends out of the side of the second connecting part 4, and a sixth reinforcing rib 84 is provided between the top of the stabilizer bar mounting part 8 and the side of the second connecting part 4. It should be noted that the stabilizer bar is a component that connects the two ends of the axle and reduces the lateral roll of the vehicle. The fixation of the stabilizer bar also requires a bearing structure component (not shown in the figure). This bearing structure component and the vehicle suspension balance beam are fixedly installed with the stabilizer bar through the sixth bolt holes 82.

[0040] In this embodiment, both the assembly surface and the nut mounting surface are planar. This design increases the contact area, further eliminates stress concentration problems, and improves connection strength and structural stability.

[0041] The above describes in detail one embodiment of the automotive suspension equalizer beam of this utility model. There are many other embodiments, which will not be elaborated here. Compared with most automotive suspension equalizer beams currently on the market, the automotive suspension equalizer beam provided by this utility model has an optimized structure. It not only integrates more peripheral functional components to meet the requirements of integrated design, but also improves the bending and torsional resistance, reduces weight, and meets the requirements of lightweight design.

[0042] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
