Description

Technical Field

[0001] The utility model relates to the technical field of balance shaft crossbeam assemblies, and particularly relates to a balance shaft crossbeam assembly. Background Art

[0002] There is a prior application No. CN202120920806.8 which discloses a balance shaft crossbeam assembly, relating to the technical field of commercial vehicle parts. It includes a crossbeam assembly, a thrust rod bracket and a connecting plate. The crossbeam assembly includes an upper crossbeam and a lower crossbeam. The upper crossbeam is a semi-surrounding structure formed in one piece. The cross-section of the semi-surrounding upper crossbeam is in a "Ji" shape. The two ends of the semi-surrounding upper crossbeam open outwards respectively in a "V" shape. The edges of the two ends of the upper crossbeam extend outwards respectively to form mounting plates. The upper crossbeam and the lower crossbeam have the same structure. The upper crossbeam and the lower crossbeam with the same structure are snap-connected. At both ends of the docking surface where the upper crossbeam and the lower crossbeam are docked, there are respectively mounting grooves. The thrust rod bracket is clamped between the upper crossbeam and the lower crossbeam through the mounting grooves. The mounting plates at both ends of the crossbeam assembly are connected with the connecting plate. The utility model optimizes the crossbeam assembly so that the crossbeam assembly can achieve the purpose of weight reduction and fuel consumption reduction on the premise of having stability and without reducing stress and stiffness.

[0003] The prior art has the following deficiencies: Although the above-mentioned balance shaft crossbeam assembly can optimize the crossbeam assembly to achieve the purpose of weight reduction and fuel consumption reduction on the premise of having stability and without reducing stress and stiffness, when the upper crossbeam and the lower crossbeam in the above balance shaft crossbeam assembly are combined, the center of the crossbeam assembly is hollow. In this way, when stressed, the middle position of the crossbeam assembly cannot provide support to the upper crossbeam and the lower crossbeam. At the same time, there is no thrust rod bracket arranged on the lower crossbeam. In this way, after long-term stress, the lower crossbeam is prone to deformation.

[0004] Therefore, it is very necessary to invent a balance shaft crossbeam assembly. Summary of the Invention

[0005] For this reason, the utility model provides a balance shaft crossbeam assembly to solve the problems in the background art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution: A balance shaft crossbeam assembly includes a crossbeam assembly. On the front and rear sides of the left and right sides of the crossbeam assembly, connecting brackets are fixedly installed. On the side of the connecting bracket away from the crossbeam assembly, there is a fixedly connected connecting long plate. A first connecting hole is opened on the outer wall of the connecting long plate;

[0007] On the outer wall of the side of the connecting bracket away from the crossbeam assembly, a second connecting hole is provided. Bolts are slidably connected to the inner walls of both the second connecting hole and the first connecting hole. A supporting device is connected to the inner wall of the crossbeam assembly, which can provide a supporting force for the entire crossbeam assembly.

[0010] Preferably, support long plates are fixedly installed at both the upper and lower ends of the inner wall of the crossbeam assembly. The two support long plates are symmetric with each other, and the opposite surfaces of the two support long plates are in contact with the opposite surfaces of the two support plates.

[0011] Preferably, a diamond-shaped through hole is provided on the outer wall of the fixing plate. The four support frames are divided into two groups, with two support frames in one group. Connecting blocks are fixedly installed on the upper, lower, left, and right sides of one group of support frames.

[0017] At the same time, the overall crossbeam assembly is integrally arranged. The support of the thrust rod bracket can prevent the overall crossbeam assembly from bending and deforming due to force. At the same time, a support frame, a connecting block, a support plate and a fixing plate are arranged in the crossbeam assembly. These components provide support for each area of the crossbeam assembly. At the same time, the shape of the support frame is "X"-shaped, with less structure and light materials, and will not add too much gravity to the crossbeam assembly.

It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0025] Refer to the attached Figures 1-5, a balance shaft crossbeam assembly provided by the present utility model. To achieve the above object, the present utility model provides the following technical solutions: It includes a crossbeam assembly 1. Connecting brackets 3 are fixedly installed on the front and rear sides of both the left and right sides of the crossbeam assembly 1. A connecting long plate 2 is fixedly connected to the side of the connecting bracket 3 away from the crossbeam assembly 1. A first connecting hole 4 is provided on the outer wall of the connecting long plate 2. A second connecting hole 5 is provided on the outer wall of the connecting bracket 3 away from the crossbeam assembly 1. Bolts 6 are slidably connected to the inner walls of both the second connecting hole 5 and the first connecting hole 4. When installing the crossbeam assembly 1, align the second connecting hole 5 on the connecting bracket 3 with the first connecting hole 4 on the connecting long plate 2, and then connect the second connecting hole 5 and the first connecting hole 4 through the thread 6, thereby installing the crossbeam assembly 1 on the connecting long plate 2 connected to the balance shaft.

[0026] A support device is connected to the inner wall of the crossbeam assembly 1. The support device includes: a support frame 13, a support plate 15, and a fixing plate 16, which can provide a supporting force for the entire crossbeam assembly 1. An anti-deformation device is installed on the outer wall of the crossbeam assembly 1. The anti-deformation device includes: a fixed short plate 7, a conical connecting block 8, and a thrust rod bracket 10, which can prevent the crossbeam assembly 1 from deforming due to force.

[0027] There are four support frames 13 and two support plates 15. The four support frames 13 are respectively installed on the inner walls of the front and rear sides of the crossbeam assembly 1. The two support plates 15 are symmetrical to each other. The opposite surfaces of the two support plates 15 are fixedly connected to the upper and lower sides of the fixing plate 16. Support long plates 12 are fixedly installed at both the upper and lower ends of the inner wall of the crossbeam assembly 1. The two support long plates 12 are symmetrical to each other. The opposite surfaces of the two support long plates 12 are in contact with the opposite surfaces of the two support plates 15. A rhombic through-hole 17 is provided on the outer wall of the fixing plate 16. The four support frames 13 are divided into two groups, with two support frames 13 in one group. Connecting blocks 14 are fixedly installed on the upper, lower, left, and right sides of one group of support frames 13. The support plate 15 inside the crossbeam assembly 1 can provide support for the outer walls on both the upper and lower sides of the crossbeam assembly 1. At the same time, for the support frame 13 inside the crossbeam assembly 1, its single overall shape is in the shape of "X", and it can support the four corners of the crossbeam assembly 1, thereby providing more support for the crossbeam assembly 1. At the same time, it has few structures, and its material is made of super-hard aluminum alloy. This material is light in weight and high in strength, and is often used in the components of aircraft. The shape formed by the combination of the support plate 15 and the fixing plate 16 is in the shape of "I", which can support the main part of the crossbeam assembly 1 and provide strong support for the crossbeam assembly 1. And the rhombic through-hole 17 provided on the fixing plate 16 makes the fixing plate 16 like a net-like structure, which is to reduce the gravity of the overall fixing plate 16. At the same time, the materials of the support plate 15 and the fixing plate 16 are also made of super-hard aluminum alloy.

[0028] There are four fixed short plates 7, and the four fixed short plates 7 are respectively distributed on the front and rear sides of the left and right sides of the crossbeam assembly 1. There are eight conical connection blocks 8. The front and rear ends of the side of the four fixed short plates 7 away from the crossbeam assembly 1 are respectively fixedly connected to the outer walls of the eight conical connection blocks 8. Connecting holes III 9 are provided on the sides of the eight conical connection blocks 8 away from the fixed short plates 7. There are four thrust rod brackets 10. The front and rear ends of the two sides of the four thrust rod brackets 10 are respectively fixedly connected to the inner walls of the connecting holes III 9. When installing the crossbeam assembly 1, to prevent the crossbeam assembly 1 from deforming, the thrust rod brackets 10 connected to the connecting holes III 9 in the conical connection blocks 8 can be integrally semi-elliptical, and can provide support forces for the front and rear sides of the crossbeam assembly 1 when the crossbeam assembly 1 is stressed. Long strip through holes 11 are symmetrically provided on the left and right sides of the crossbeam assembly 1. To reduce the overall weight of the crossbeam assembly 1, long strip through holes 11 are provided on the left and right sides of the crossbeam assembly 1, thereby reducing the weight of the overall crossbeam assembly 1.

[0029] The use process of the present utility model is as follows: When installing the crossbeam assembly 1, align the connecting holes II 5 on the connecting bracket 3 with the connecting holes I 4 on the connecting long plate 2, and then connect the connecting holes II 5 and the connecting holes I 4 through the threads 6, thereby installing the crossbeam assembly 1 on the connecting long plate 2 connected to the balance shaft. When the crossbeam assembly 1 is stressed, the support frames 13 can support the four corners of the crossbeam assembly 1, and the support plates 15 can provide support for the outer walls on the upper and lower sides of the crossbeam assembly 1, and can also support the main body part of the crossbeam assembly 1. In this way, the crossbeam assembly 1 can bear more gravity, and at the same time prevent the crossbeam assembly 1 from being too heavy for the connecting long plate 2 to bear. Long strip through holes 11 are provided on the left and right sides of the crossbeam assembly 1, thereby reducing the weight of the overall crossbeam assembly 1. The diamond-shaped through holes 17 provided on the fixing plate 16 make the fixing plate 16 like a net-like structure, thereby reducing the overall volume and area of the fixing plate 16, thereby reducing the gravity of the overall fixing plate 16, and thus reducing the weight of the overall crossbeam assembly 1.

[0030] The above is only a preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
