Description

Technical Field

[0001] The utility model relates to the technical field related to double-airbag air suspension, in particular to a double-airbag air suspension assembly for a new energy heavy truck. Background Art

[0002] New energy heavy-duty trucks adopt a four-airbag suspension structure, and the four airbags are responsible for load-bearing and vibration reduction in the up and down directions; the front and rear forces (vehicle driving force and braking force) are supported by two I-shaped thrust rods at the bottom and a V-shaped thrust rod at the top; the lateral forces (turning) are supported by a V-shaped thrust rod at the top, which can decompose the two components of force in the front and rear and left and right directions; because the air suspension has poorer anti-roll ability than leaf springs, it must be matched with a lateral stabilizer bar.

[0003] When the existing dual-airbag air suspension airbags are not inflated, the gravity of the cargo on the new energy heavy-duty truck will damage the dual-airbag air suspension, reducing the vibration damping and rigidity of the dual-airbag air suspension. The dual airbags will shrink and wear during each take-off and landing, causing creases on the bottom of the dual airbags, reducing the service life of the dual airbags. Utility Model Content

[0004] The purpose of the utility model is to provide a double-airbag air suspension assembly for a new energy heavy truck to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double airbag air suspension assembly for a new energy heavy truck includes a new energy heavy truck crossbeam, a double airbag fixing frame, a heavy truck frame, and an anti-damage fixing component. The new energy heavy truck crossbeam is threadedly fixed with a double airbag fixing frame around the periphery, the heavy truck frame is fixedly installed inside the double airbag fixing frame, the airbag fixing position on the anti-damage fixing component is provided with a double airbag fixing frame, and also includes,

[0007] A folding assembly, mounted on the dual airbag fixing frame;

[0008] A compression-resistant component, arranged on the dual airbag fixing frame;

[0009] Among them, a support frame is fixed to the bottom end of the dual airbag fixing frame, a dual airbag mounting frame is fixedly connected to the bottom end of the support frame, a dual airbag is fixedly installed on the bottom end of the dual airbag mounting frame, the external movable installation of the dual airbag is wrapped with a soft connection cover, a dual airbag base is fixed to the bottom end of the dual airbag, a lower support frame is welded to the bottom end of the dual airbag base, two lower support frames are provided, and the four dual airbags are fixedly installed on the two lower support frames respectively.

[0010] As described above, in the dual-airbag air suspension assembly for new energy heavy-duty trucks, the soft connection cover is fixedly mounted on the outside of the four dual airbags via a dual airbag mounting frame, and the soft connection cover is folded and wrapped around the outside of the dual airbags.

[0011] The dual-airbag air suspension assembly for a new energy heavy-duty truck as described above: the new energy heavy-duty truck crossbeam is fixedly connected to the four dual airbags via a dual-airbag fixing frame.

[0012] As described above, the dual-airbag air suspension assembly for new energy heavy trucks: the folding component includes a mounting hole opened inside the dual-airbag fixing frame, and a built-in spring cover is movably installed inside the soft connection cover.

[0013] The dual-airbag air suspension assembly for new energy heavy trucks as described above: the soft connection cover is deployed outside the dual airbags by reciprocating rebound through the built-in spring cover.

[0014] As described above, the dual-airbag air suspension assembly for new energy heavy trucks: the pressure-resistant component includes a fixing plate fixedly connected around the dual-airbag base, an inflatable airbag is fixedly installed on the top of the fixing plate, and an upper airbag is arranged on the top of the inflatable airbag.

[0015] The dual-airbag air suspension assembly for a new energy heavy truck as described above: after the upper airbag and the inflatable airbag are inflated, the upper airbag is supported on the bottom end of the dual airbag.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the soft connection cover is wrapped around the outside of the four dual airbags, and the soft connection cover is folded and raised and lowered along with the four dual airbags. When the dual airbag air suspension airbags are not inflated, the built-in spring cover inside the soft connection cover rebounds and unfolds inside the soft connection cover. The soft connection cover can elastically unfold outside the four dual airbags to isolate the outside from the outside, preventing dust and aqueous solutions from entering the outside of the four dual airbags, and having an external anti-corrosion effect on the four dual airbags. The soft connection cover is sandwiched at the folding point of the four dual airbags to prevent the new energy heavy truck's own cargo gravity from damaging the dual airbag air suspension, which is beneficial to maintaining the vibration damping and rigidity of the dual airbag air suspension.

[0017] Each time the four double airbags move back and forth, the upper airbag and the inflatable airbag can be elastically supported at their bottom. The softness of the upper airbag and the inflatable airbag themselves can prevent the double airbag base from directly colliding with the outside of the four double airbags, reducing the folding creases of the four double airbags, and preventing the double airbags from shrinking and wearing during each take-off and landing. The upper airbag and the inflatable airbag avoid shrinkage creases at the bottom of the double airbags and extend the service life of the four double airbags. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment, four support frames 4 are distributed and fixedly connected to the bottom end of the dual airbag fixing frame 2, so that four dual airbags 7 are distributedly installed on the four support frames 4 through the dual airbag mounting frame 5, and then the soft connection cover 6 is wrapped around the outside of the four dual airbags 7 for dust and fire prevention installation. The four dual airbags 7 are fixedly connected to the lower support frame 9 through the dual airbag base 8. The lower support frame 9, the new energy heavy truck crossbeam 1 and the dual airbag fixing frame 2 are installed on the bottom end of the new energy heavy truck with a threaded structure. The four dual airbags 7 are inflated by the new energy heavy truck for take-off and landing.

[0030] Preferably, the soft connection cover 6 is fixedly mounted on the outside of the four dual airbags 7 through the dual airbag mounting frame 5, and the soft connection cover 6 is folded and wrapped around the outside of the dual airbags 7. The soft connection cover 6 is threadedly fastened to the four support frames 4 through the dual airbag mounting frame 5, so that the soft connection cover 6 is wrapped around the outside of the four dual airbags 7, and the soft connection cover 6 is folded and raised along with the four dual airbags 7, so as to provide an isolation and protection effect on the four dual airbags 7.

[0031] Preferably, the new energy heavy-duty truck crossbeam 1 is fixedly connected to four dual airbags 7 through a dual airbag fixing frame 2, and the four dual airbags 7 are fixedly installed through the dual airbag fixing frame 2 and the new energy heavy-duty truck crossbeam 1. When the four dual airbags 7 are inflated by the new energy heavy-duty truck for take-off and landing, the dual airbag fixing frame 2 and the new energy heavy-duty truck crossbeam 1 can be lifted by air for take-off and landing.

[0032] Please refer to Figure 1 and Figure 2 In this embodiment, the folding assembly includes a mounting hole 10 opened inside the dual airbag fixing frame 2, and a built-in spring cover 11 is movably installed inside the soft connection cover 6.

[0033] The mounting hole 10 inside the dual airbag fixing frame 2 can be threaded with a bolt to reinforce the dual airbag air suspension assembly. The built-in spring cover 11 on the soft connection cover 6 is unfolded as the four dual airbags 7 are inflated and lifted.

The soft connection cover 6 can be elastically unfolded outside the four dual airbags 7 to isolate the outside from the outside, prevent dust and aqueous solutions from entering the outside of the four dual airbags 7, and have an external anti-corrosion effect on the four dual airbags 7.

[0035] Please refer to Figure 1 and Figure 3 In this embodiment, the pressure-resistant component includes a fixing plate 12 fixedly connected to the four sides of the dual airbag base 8, an inflatable airbag 13 is fixedly installed on the top of the fixing plate 12, and an upper airbag 14 is arranged on the top of the inflatable airbag 13.

[0036] The four dual airbags 7 are fixedly connected to the lower support frame 9 through the dual airbag base 8. The fixing plate 12 on the dual airbag base 8 is provided with an inflatable airbag 13 and an upper airbag 14. When the new energy heavy truck is started, the inflatable airbag 13 and the upper airbag 14 can be inflated, so that the inflated inflatable airbag 13 and the upper airbag 14 can be supported on all sides of the dual airbag base 8 and positioned and installed through the fixing plate 12. When the four dual airbags 7 are not started, they can be retracted to the dual airbag base 8, so that the inflated inflatable airbag 13 and the upper airbag 14 are supported on the bottom ends of the four dual airbags 7, and the four dual airbags 7 can be elastically supported to prevent the four dual airbags 7 from being damaged and shrinking on the dual airbag base 8.

[0037] Preferably, after the upper airbag 14 and the inflatable airbag 13 are inflated, the upper airbag 14 is supported at the bottom of the dual airbag 7. When the four dual airbags 7 are driven by a new energy heavy truck, air suspension support can be performed. After the upper airbag 14 and the inflatable airbag 13 are inflated, they can be expanded and supported at the bottom of the four dual airbags 7. Each time the four dual airbags 7 reciprocate, the upper airbag 14 and the inflatable airbag 13 can be elastically supported at their bottoms. The softness of the upper airbag 14 and the inflatable airbag 13 prevents the dual airbag base 8 from directly colliding with the outside of the four dual airbags 7, reduces the folding creases of the four dual airbags 7, and prolongs the service life of the four dual airbags 7.

[0038] As can be seen from the above, the dual airbag mounting frame 5 is distributed and installed on four support frames 4, and then the soft connection cover 6 is wrapped around the outside of the four dual airbags 7 for dust and fire proof installation.

The soft connection cover 6 can be elastically unfolded outside the four dual airbags 7 for external isolation.

[0039] When starting a new energy heavy-duty truck, the inflatable airbag 13 and the upper airbag 14 can be inflated, so that the inflated inflatable airbag 13 and the upper airbag 14 can be supported on all sides of the dual airbag base 8, and positioned and installed through the fixing plate 12. When the four dual airbags 7 are not started, they can be retracted to the dual airbag base 8, so that the inflated inflatable airbag 13 and the upper airbag 14 are supported on the bottom ends of the four dual airbags 7, and the four dual airbags 7 can be elastically supported.
