Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to an integrated shock-absorbing housing for a three-wheeled vehicle gearbox. Background Technology

[0002] Three-wheeled vehicles are an important means of transportation for short-distance freight transport and daily commuting in urban and rural areas. They are widely used in agricultural product transportation, small commodity delivery, and rural travel scenarios. Their operating environment often involves unpaved roads such as gravel roads and rural dirt roads in urban-rural fringe areas. The road surface is bumpy and impacted frequently, and they often need to switch between empty and fully loaded, which places high demands on the shock absorption performance of the gearbox.

[0003] Currently, most tricycle gearbox housings use rigid casting structures. Although some have added shock-absorbing components, there are still obvious defects: First, the existing buffer structures are mostly added later and are not integrally formed with the housing. After long-term vibration, they are prone to loosening and falling off. Moreover, relying on a single buffer element cannot effectively dissipate high-frequency transmission vibrations, such as gear meshing vibrations and low-frequency road impacts, leading to accelerated wear of bearings and gears inside the gearbox, shortening its service life. At the same time, the vibration transmitted to the vehicle body will also exacerbate the driving bumps. Second, the buffer parameters are fixed and cannot be adjusted, making it impossible to adapt to different working conditions. When the vehicle is empty, the buffer stiffness is too high, and even slight road bumps are transmitted to the housing, resulting in poor comfort. When fully loaded, the buffer stiffness is insufficient and cannot withstand the instantaneous impact of heavy loads, which can easily cause the shock-absorbing components to overload and fail, thus limiting adaptability and practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing buffer structures are mostly added later and are not integrally formed with the shell. After long-term vibration, they are prone to loosening and falling off, and the buffer parameters are fixed and cannot be adjusted, making them unsuitable for different working conditions.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an integrated shock-absorbing housing for a three-wheeled vehicle gearbox: comprising a gearbox body and a housing body, and further comprising: A buffer assembly is disposed inside the outer shell body and includes a mounting groove formed on the outer surface of the outer shell body, wherein a support plate is embedded inside the mounting groove. The adjustment component is located inside the support plate.

[0006] In a preferred embodiment, the buffer component further includes: A buffer chamber is formed on the inner wall of the mounting slot; The spring clip is fixed to one side surface of the buffer chamber.

[0007] In a preferred embodiment, the buffer component further includes: The damper is installed on one side surface of the support plate; A spring is fitted onto one side of the damper surface.

[0008] In a preferred embodiment, the buffer component further includes: The support component is fixed to one end of the damper; One side of the support component is attached to one side of the spring sheet.

[0009] In a preferred embodiment, the buffer component further includes: Four limiting grooves are provided and are formed on the inner wall surface of the buffer chamber; Four limit sliders are provided and fixed to the outer surface of the support member; The outer surfaces of the four limit sliders are embedded inside the limit grooves.

[0010] In a preferred embodiment, the adjustment component includes: The adjusting column is rotatably connected to one side of the support plate via a bearing; The guide groove is located on one side of the support plate; The push ring is embedded inside the guide groove and threaded to the outer surface of the adjusting column; The guide block is fixed to the outer surface of the push ring; The outer surface of the guide block is embedded inside the guide groove.

[0011] In a preferred embodiment, the inner diameter of the push ring is greater than or equal to the diameter of the damper.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, the vibration of the gearbox body is transmitted to the outer shell body, compressing the spring sheet to absorb energy and then transmitting the force to the damper and spring. The spring is compressed and converts kinetic energy into elastic potential energy. The damper dissipates the vibration energy in a multi-stage buffering manner, ensuring the integrity of the structure and the shock absorption effect, while avoiding the offset of the support components and enhancing the reliability of the support.

[0013] This invention utilizes a rotating adjusting column with a slot at one end to drive a push ring via a thread. Guided by a guide block and guide groove, the push ring moves smoothly along the damper, pushing a spring to adjust its pre-compression. When the gearbox transmits vibrations, the support component stably transmits force, while the spring, damper, and spring plate provide graded buffering. The adjusting assembly can flexibly adapt to different vibration scenarios, adding adjustable buffering parameters and improving the housing's adaptability to different road conditions and load scenarios.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] Please see Figures 1-5 This embodiment provides an integrated shock absorber housing for a three-wheeled vehicle gearbox, the specific concept of which is as follows: In one specific implementation, the gearbox body 1 and the housing body 2 further include: A buffer assembly is disposed inside the outer shell 2, including a mounting groove 3, which is opened on the outer surface of the outer shell 2, and a support plate 4 is embedded inside the mounting groove 3. The adjustment component is located inside the support plate 4.

[0018] As one specific implementation, the buffer component also includes: The buffer chamber 10 is formed on the inner wall of the mounting groove 3; The spring clip 9 is fixed to one side surface of the buffer chamber 10.

[0019] As one specific implementation, the buffer component also includes: The damper 12 is disposed on one side surface of the support plate 4; Spring 11 is fitted onto one side surface of damper 12.

[0020] As one specific implementation, the buffer component also includes: Support 13 is fixed to one end of damper 12; One side surface of the support member 13 is attached to one side of the spring piece 9.

[0021] As one specific implementation, the buffer component also includes: Four limiting grooves 15 are provided and are formed on the inner wall surface of the buffer chamber 10; Four limit sliders 14 are provided and fixed to the outer surface of the support member 13; The outer surfaces of the four limiting sliders 14 are embedded inside the limiting grooves 15.

[0022] In this embodiment, the specific type of the buffer assembly can be various, and this application does not limit it. In an optional embodiment, as an example of a buffer assembly, the buffer assembly includes: a mounting groove 3, a support plate 4, a spring 9, a buffer chamber 10, a spring 11, a damper 12, a support member 13, a limiting slider 14, and a limiting groove 15. The specific quantity of each component is as follows: Figures 2-5 As shown, the settings are as follows: In this embodiment, an installation groove 3 is provided, which is integrally formed with the support plate 4 through a mold.

[0023] The support plate 4, which provides support force, is fixed inside the mounting groove 3 by multiple cross bolts; The energy-absorbing spring 9 is integrally formed with the buffer chamber 10; The buffer chamber 10, which provides space, is integrally formed with the mounting groove 3 by a mold; The spring 11, which absorbs kinetic energy, is fixed to one side of the support 13. When subjected to force, it compresses and converts the pressure into elastic potential energy. The damper 12 for cushioning is fixed to one side of the support 13; The support member 13 for guiding force is embedded inside the buffer chamber 10. When the spring 9 is deformed by force, the force is transmitted through the support member 13, and the support member 13 transmits the force to the spring 11 and the damper 12. The limiting slider 14, which provides support, is welded to the outer surface of the support member 13; A limiting groove 15 for providing a displacement trajectory is formed on the inner wall surface of the buffer chamber 10.

[0024] In this embodiment, during use, the mounting groove 3 and the buffer chamber 10 are integrally formed by a mold and the outer shell body 2. The support plate 4 in the mounting groove 3 is fixed by multiple cross bolts. The spring piece 9 is integrally formed with the buffer chamber 10. The support member 13 is embedded in the buffer chamber 10, and the limiting slider 14 on its outer surface is embedded in the limiting groove 15 on the inner wall of the buffer chamber 10. The damper 12 is fixed on one side of the support member 13, and the spring 11 is sleeved on the outside of the damper 12. At the same time, the spring piece 9 is attached to the other side of the support member 13. During use, the vibration of the gearbox body 1 is transmitted to the outer shell body 2, which drives the buffer chamber 10. The support member 13 is subjected to vibration. Under force, the device moves stably along the limiting slide groove 15 guided by the limiting slider 14. On the one hand, it compresses the spring 9 to deform and absorb energy, and on the other hand, it transmits the force to the damper 12 and the spring 11. The spring 11 is compressed to convert kinetic energy into elastic potential energy, and the damper 12 dissipates vibration energy simultaneously, achieving multi-level buffering. The integral molding of multiple components ensures the integrity of the structure. The synergy of the spring 9, spring 11 and damper 12 achieves efficient vibration reduction. The limiting structure prevents the support 13 from shifting, and the bolt-fixed support plate 4 enhances the reliability of the support, effectively protecting the internal parts of the gearbox and improving driving stability, while also taking into account the ease of assembly and structural durability. Example 2

[0025] like Figures 1-5 As shown, based on Embodiment 1, this embodiment also provides an adjustment component, which is disposed inside the support plate 4 and includes an adjustment column 5, which is rotatably connected to one side of the support plate 4 via a bearing; The guide groove 6 is located on one side of the support plate 4; The push ring 8 is embedded inside the guide groove 6 and threadedly connected to the outer surface of the adjusting column 5; Guide block 7 is fixed to the outer surface of push ring 8; The outer surface of the guide block 7 is embedded inside the guide groove 6.

[0026] In one specific implementation, the inner diameter of the thrust ring 8 is greater than or equal to the diameter of the damper 12.

[0027] In this embodiment, during use, the adjusting column 5 is rotated by rotating the slot at one end of the adjusting column 5, which drives the push ring 8 to move through the thread. Under the guidance of the guide block 7 and the guide groove 6, the push ring 8 moves smoothly along the damper 12, pushing the spring 11 and adjusting the pre-compression of the spring 11. When the gearbox vibrates, the support member 13 transmits force stably, and the spring 9, spring 11 and damper 12 provide graded buffering. The adjusting component can flexibly adapt to different vibration scenarios. This setting not only ensures the stability of the adjustment process through the guiding structure, but also ensures compatibility with the buffer component through the adaptability of the push ring 8. While retaining the integrity of the original one-piece molded structure and the efficient shock absorption capability, it adds the function of adjustable buffer parameters, improving the adaptability of the housing to different road conditions and load scenarios.

[0028] Working principle: The vibration of the oil inside the gearbox body 1 is transmitted to the outer shell body 2. The spring 9, which is integrally formed with itself in the buffer chamber 10, deforms under the force of vibration. The force generated by the deformation is transmitted to the attached support member 13. The support member 13 moves in a direction along the limiting slide groove 15 opened in the inner wall of the buffer chamber 10 through the limiting slider 14 welded to the outer surface. At the same time, it transmits the force to the damper 12 fixed on one side and the spring 11 sleeved on the outside of the damper 12. The spring 11 is compressed by pressure, converting kinetic energy into elastic potential energy. The damper 12 works synchronously to dissipate vibration energy, realizing multi-stage buffering of vibration. The support plate 4, which is fixed in the mounting groove 3 by cross bolts, provides stable support for the damper 12.

[0029] During adjustment, the adjusting column 5 is rotated through the slot at one end. The adjusting column 5 rotates on one side of the support plate 4 via the bearing. Since the push ring 8 is threadedly connected to the adjusting column 5, and the guide block 7 fixed on the outer surface of the push ring 8 is embedded in the guide groove 6 opened on one side of the support plate 4, the rotation of the adjusting column 5 drives the push ring 8 to move smoothly along the guide groove 6. During the movement of the push ring 8, it pushes the spring 11 and changes the pre-compression of the spring 11. The inner diameter of the push ring 8 is greater than or equal to the diameter of the damper 12 to ensure that the push ring 8 does not interfere with the damper 12 when it moves.
