Description

Technical Field

[0001] This application belongs to the field of transmission technology and relates to a transmission and a vehicle. Background Technology

[0002] During vehicle operation, the transmission, as a critical power transmission component, directly affects the overall operating condition and service life of the vehicle. With the widespread application of heavy-duty vehicles in engineering construction, logistics transportation, and other fields, and with the continuous development of technology, most heavy-duty vehicles on the market have increasingly higher requirements for the cleanliness of the transmission lubricating oil and the oil change interval.

[0003] Currently, in order to ensure the cleanliness of transmission lubricating oil, a filter is usually installed on the transmission housing. The lubricating oil inside the housing is transported to the filter for filtration and then returned to the housing, thus achieving the effect of cleaning the lubricating oil through circulation.

[0004] However, for vehicles with a large transmission cavity volume, there is a lot of lubricating oil that needs to be filtered inside, so multiple filters are required. Multiple filters mean that multiple inlet and outlet pipes need to be installed. These pipes are usually installed directly on the cavity wall, which has poor fixing effect and is prone to falling off after long-term use. Utility Model Content

[0005] This application provides a transmission and a vehicle, which uses two support components to fix the inlet and outlet components inside the transmission, making the fixation of the inlet and outlet components more stable.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The terms "first," "second," "third," "fourth," etc. (if applicable) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. In embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0040] Heavy-duty vehicles play a vital role in modern transportation and engineering construction, and are widely used in many scenarios such as engineering construction and logistics transportation. The operating conditions of heavy-duty vehicles are often complex and harsh, requiring long-term, high-intensity continuous operation, which places stringent requirements on the performance and reliability of the vehicle's key components.

[0041] Among them, the transmission, as a key power transmission component of a vehicle, occupies a central position in the entire vehicle power transmission chain. Its performance stability is directly related to the overall operating status and service life of the vehicle. During the operation of heavy-duty vehicles, numerous transmission parts inside the transmission work together, and lubricating oil plays an indispensable role in lubrication, heat dissipation, and cleaning, ensuring the normal operation of each component.

[0042] However, most heavy-duty transmission assemblies on the market currently have certain limitations in their design, generally employing a design with only one filter. In the actual application scenarios of heavy-duty vehicles, the internal volume of the transmission cavity is usually large, designed to hold more lubricating oil to meet the heat dissipation and lubrication requirements under complex operating conditions. However, the filtration capacity of a single filter is relatively limited, making it difficult to fully and efficiently filter the lubricating oil in the transmission, given the large amount of lubricating oil and the impurities continuously generated during long-term operation.

[0043] This inadequate filtration means that impurities remaining in the lubricating oil cannot be effectively removed. These impurities circulate within the transmission along with the lubricating oil, continuously causing wear, corrosion, and other damage to various transmission components. Over time, this significantly increases the failure rate of transmission components within the transmission, affecting not only the normal operation of the transmission itself but also potentially leading to unstable power transmission, reduced work efficiency, and even impacting the normal use of heavy vehicles in critical business operations such as engineering construction and logistics transportation due to frequent breakdowns and repairs, thus increasing operating and time costs.

[0044] In summary, the transmission provided in this application embodiment, by incorporating two filter components, can significantly improve the filtration capacity and efficiency of the liquid to be filtered within the housing, thereby extending the service life of the transmission. The embodiment will now be further described in conjunction with the accompanying drawings.

Figure 3 for Figure 2 Sectional view at point AA. Figure 4 for Figure 1 Rear view of the transmission. Figure 5 for Figure 1 A schematic diagram of the supporting components.

[0046] like Figures 1-5 As shown in the illustration, an embodiment of this application provides a transmission including a housing 100, at least two filter assemblies 200, a liquid inlet assembly 300, and a liquid outlet assembly 400. The filter assemblies 200 are disposed on the housing 100. The liquid inlet assembly 300 is disposed within the housing 100 and connected to the two filter assemblies 200, and is used to supply the liquid to be filtered from within the housing 100 to the filter assemblies 200. The liquid outlet assembly 400 is disposed within the housing 100 and connected to the two filter assemblies 200, and is used to supply the filtered liquid from the filter assemblies 200 into the housing 100.

[0047] The housing 100 serves as the basic support structure for the transmission. Its interior forms a space to accommodate the various functional components of the transmission and the fluid, while its exterior provides protection and fixation. Meanwhile, two filter components 200 are mounted on the housing 100, providing a mounting base and a relatively stable working environment for the filter components 200.

[0048] Two filter components 200 are symmetrically arranged on opposite sides of the housing 100, or can be rationally arranged on the housing 100 according to the internal space layout. They are mainly used for effective impurity separation of the incoming liquid to be filtered. The filter components 200 internally employ a combination of multiple layers of filter screens with different precision. The outer filter screen intercepts larger particles, while the inner filter screen further filters finer particles, ensuring that the filtered liquid meets a high cleanliness standard and satisfies the cleanliness requirements of various components within the transmission.

[0049] The liquid inlet assembly 300 is disposed inside the housing 100 and is connected to the two filter assemblies 200. It has a power component (such as a small hydraulic pump) or makes reasonable use of the pressure transmission mechanism of the liquid inside the housing 100 to deliver the liquid to be filtered inside the housing 100 to the filter assembly 200.

[0050] The liquid outlet assembly 400 is also located within the housing 100 and is connected to the two filter assemblies 200. After the filter assemblies 200 complete the filtration of the liquid to be filtered, the liquid outlet assembly 400 is responsible for transporting the filtered liquid back into the housing 100 so that the clean liquid can continue to participate in the lubrication, hydraulic transmission and other related work inside the transmission.

[0051] When the transmission starts operating, the liquid to be filtered within the housing 100 flows to the two filter assemblies 200 according to a set flow rate and path under the action of the inlet assembly 300 or the pressure within the housing 100. After entering the filter assembly 200, impurities are intercepted by the filter screen and other filtration structures, while the clean liquid flows through the filter assembly 200 to the outlet assembly 400. The outlet assembly 400 then returns the filtered liquid to the housing 100, where it re-enters the transmission's operation, such as providing lubrication for gears, shafts, and other components, or serving as a transmission medium for the hydraulic control system. This entire process is continuously cyclical, ensuring that the liquid within the housing 100 remains in a relatively clean state that meets operational requirements.

[0052] By setting two filter components 200, parallel filtration channels are increased, which can process more liquid to be filtered per unit time compared with traditional single filter devices, greatly improving filtration efficiency and effectively reducing the accumulation rate of impurities in the housing 100.

[0053] In this embodiment of the application, a support component 500 is also included. The support component 500 is disposed inside the housing 100. The liquid inlet component 300 and the liquid outlet component 400 are both disposed on the support component 500. The support component 500 is used to fix the liquid inlet component 300 and the liquid outlet component 400.

[0054] The support assembly 500 is disposed within the housing 100 and is used to fix the liquid inlet assembly 300 and the liquid outlet assembly 400. The liquid inlet assembly 300 and the liquid outlet assembly 400 can be disposed outside the support assembly 500 or inside the support assembly 500. The implementation method of being disposed inside the support assembly 500 will be further described below.

[0055] In this embodiment of the application, a recirculation component 700 is also included, and the support component 500 includes a support plate 510.

[0056] The support plate 510 is disposed inside the housing 100 and divides the inner cavity of the housing 100 into a first cavity 110 and a second cavity 120. The support plate 510 has a liquid inlet hole 511 on the side wall facing the first cavity 110 and a liquid outlet hole 512 on the side wall facing the second cavity 120.

[0057] Both the liquid inlet assembly 300 and the liquid outlet assembly 400 are mounted on the support plate 510. The liquid inlet assembly 300 is connected to the liquid inlet hole 511. The liquid to be filtered in the first cavity 110 enters the liquid inlet assembly 300 through the liquid inlet hole 511 and is then transported to the filter assembly 200 through the liquid inlet assembly 300.

[0058] The liquid outlet assembly 400 is connected to the liquid outlet hole 512, and the liquid outlet assembly 400 delivers the filtered liquid flowing out of the filter assembly 200 to the second cavity 120 through the liquid outlet hole 512.

[0059] The reflux assembly 700 is disposed on the housing 100 and is used to transport the filtered liquid in the second chamber 120 to the first chamber 110.

[0060] Both the liquid inlet assembly 300 and the liquid outlet assembly 400 are installed inside the support plate 510. The liquid inlet assembly 300 is connected to the liquid inlet hole, and the liquid outlet assembly 400 is connected to the liquid outlet hole.

[0061] Both the liquid inlet assembly 300 and the liquid outlet assembly 400 are arranged inside the support plate 510 and are connected to the liquid inlet hole 511 and the liquid outlet hole 512 respectively. The reflux assembly 700 is arranged on the outside of the housing 100 and its function is to realize the circulation of liquid between the second cavity 120 and the first cavity 110.

[0062] The liquid to be filtered is stored in the first chamber 110. Under pressure, the liquid enters the inlet assembly 300 through the inlet port 511 and is then transported to the filter assembly 200 for filtration. The filtered liquid flows out of the filter assembly 200, enters the outlet assembly 400, and is then transported to the second chamber 120 through the outlet port 512. The reflux assembly 700 returns a portion of the filtered liquid in the second chamber 120 back to the first chamber 110, forming a circulating filtration process to improve the filtration effect.

[0063] The filter component 200 adopts a multi-layer filter structure, which can effectively remove impurities, particulate matter and microorganisms from the liquid, thereby obtaining a purified liquid.

[0064] Both the first and second chambers are used to house transmission components. The first chamber is under high pressure, which forces the filtered liquid through the inlet port into the inlet assembly 300, and then into the filter assembly 200. The filtered liquid passes through the outlet assembly 400 and is finally delivered to the second chamber through the outlet port.

[0065] In this embodiment of the application, the liquid inlet assembly 300 includes a liquid inlet pipe 310 and at least two first connecting pipes 320 connected to both ends of the liquid inlet pipe 310.

[0066] Both the liquid inlet pipe 310 and the first connecting pipe 320 are installed inside the support plate 510. The first connecting pipe 320 is connected to the corresponding filter component 200, and the liquid inlet pipe 310 is connected to the liquid inlet hole 511.

[0067] The inlet pipe 310 and the first connecting pipe 320 can be separate pipes or pipes installed within the support plate 510. The two first connecting pipes 320 are positioned opposite each other at the ends of the inlet pipe 310. Each first connecting pipe 320 is connected to a corresponding filter assembly 200, evenly distributing the liquid to be filtered flowing from the inlet pipe 310 into the two filter assemblies 200. The first connecting pipes 320 are connected using joints with good sealing performance to prevent liquid leakage.

[0068] In this embodiment, the liquid outlet assembly 400 includes two liquid outlet pipes 410 and at least two second connecting pipes 420. Both the liquid outlet pipes 410 and the second connecting pipes 420 are disposed within the support plate 510. The liquid outlet pipes 410 are connected to corresponding liquid outlet holes 512, and the two ends of the second connecting pipes 420 are respectively connected to the corresponding liquid outlet pipe 410 and the filter assembly 200.

[0069] The second connecting pipe 420 introduces the filtered clean liquid from the filter assembly 200 into the outlet pipe 410, and then delivers it back to the various working parts of the transmission through the outlet hole to complete the circulation of the liquid.

[0070] When the transmission starts operating, the liquid to be filtered inside the housing 100 enters the inlet pipe 310 through the inlet port. Since the inlet pipe 310 is connected to two first connecting pipes 320, the liquid to be filtered is evenly distributed into the two first connecting pipes 320, and then flows through the first connecting pipes 320 into the corresponding filter assembly 200 for filtration. In the filter assembly 200, impurities are intercepted by multiple layers of filter screens, and the clean liquid enters the second chamber. Next, the clean liquid flows through the second connecting pipe 420 into the outlet pipe 410, and then through the outlet port back to the various working parts of the transmission, such as gears and bearings, providing lubrication and cooling, forming a complete and efficient liquid circulation system.

[0071] The two first connecting pipes 320 are connected by a liquid inlet pipe 310, allowing liquid to enter the filter components 200 at both ends simultaneously. The two second connecting pipes 420 are each connected to a separate liquid outlet pipe 410 to prevent the liquid in the two second connecting pipes 420 from squeezing each other during the liquid outlet process, which would cause the liquid to flow back into the filter component 200.

[0072] The unique design of the inlet component 300 and the outlet component 400 allows the liquid to be filtered to be evenly distributed to the two filter components 200 for filtration. At the same time, the filtered clean liquid can flow smoothly back to the working parts of the transmission, greatly improving the efficiency of liquid circulation and filtration effect.

[0073] In this embodiment of the application, the filter assembly 200 includes a connecting plate 210, a filter pipe 220, and a filter 230;

[0074] The connecting plate 210 is detachably connected to the housing 100. The filter pipe 220 and the filter 230 are both mounted on the connecting plate 210. One end of the filter pipe 220 is connected to the first connecting pipe 320 and the second connecting pipe 420 respectively, and the other end of the filter pipe 220 is connected to the inlet and outlet of the filter 230 respectively.

[0075] The connecting plate 210 is detachably connected to the housing 100, for example, by bolts or a snap-fit ​​mechanism. This design makes the installation and removal of the filter assembly 200 very convenient, facilitating regular maintenance and replacement of the filter 230. A sealing ring is also provided on the connecting plate 210 to ensure a tight seal when connected to the housing 100, preventing liquid leakage.

[0076] One end of the filter pipe 220 is connected to the first connecting pipe 320 and the second connecting pipe 420 respectively, using a joint with good sealing performance to ensure no leakage of liquid during transportation. The other end of the filter pipe 220 is connected to the inlet and outlet of the filter 230 respectively, providing a flow channel for liquid from the inlet assembly 300 to the filter 230 and then to the outlet assembly 400.

[0077] Filter 230 is the core component of filter assembly 200. It uses multiple layers of filter materials of different precision, such as filter paper and filter screen, to effectively intercept impurities in the liquid to be filtered, including metal particles, dirt, oxides, etc. The inlet and outlet of filter 230 are tightly connected to filter pipe 220 to ensure that the liquid can be fully filtered through the filter materials.

[0078] The connecting plate 210 of the filter assembly 200 is detachably connected to the housing 100, which makes the replacement and maintenance of the filter 230 simple and quick, reduces downtime and improves work efficiency.

[0079] It should be noted that all of the above-mentioned pipeline connections are sealed connections, and all connections can be sealed with sealing rings. Since sealed connections are existing technology, they will not be described in detail in this embodiment.

[0080] In this embodiment of the application, at least one filter component 200 is at least partially disposed above the housing 100.

[0081] For example, the filter 230 is disposed on the side of the connecting plate 210 near the housing 100.

[0082] By placing the filter 230 on the side of the connecting plate 210 close to the housing 100, the space between the housing 100 and the connecting plate 210 is fully utilized, making the structure of the entire filter assembly 200 more compact.

[0083] In this embodiment, a cover plate 600 is also included. The cover plate 600 is detachably connected to the housing 100. The cover plate 600 is used to block the first connecting pipe 320 and the second connecting pipe 420 that are exposed when the connecting plate 210 is disassembled.

[0084] The cover plate 600 and the housing 100 are detachably connected, for example by snap-fit ​​or screw fixing, to facilitate installation and disassembly. Its main function is to seal the first connecting pipe 320 and the second connecting pipe 420 exposed when the filter assembly 200 is disassembled due to the removal of the connecting plate 210, to prevent external impurities from entering the pipes and to prevent the pipes from being damaged by accidental collisions.

[0085] The size and shape of the cover plate 600 are adapted to the area that needs to be sealed, and a sealing structure (such as a rubber sealing strip) is provided on the edge of the cover plate that contacts the housing 100 and at the corresponding part of the sealed pipeline to ensure the sealing performance and prevent dust, debris and other objects from entering the pipeline through gaps.

[0086] When the transmission only requires one filter 230 for filtration, one of the filters 230 can be removed using a cover plate 600 and then sealed using the cover plate 600.

[0087] For example, the housing 100 is provided with a filter 230 with a connecting plate 210 and a filter 230 without a connecting plate 210 at both ends. One filter 230 extends to the top of the housing 100 through the connecting plate 210, which can avoid the components on the side of the housing 100. The other filter 230 without a connecting plate 210 is directly connected to the first connecting pipe and the second connecting pipe inside the housing 100.

[0088] In this embodiment, the cover plate 600 has a different shape design because the connection structure between the two ends of the housing 100 and the filter 230 is different.

[0089] In this embodiment, the height of the filter 230 is higher than the height of the housing 100. Maintenance work can be performed directly from the portion above the housing 100, eliminating the need to access the narrow interior of the vehicle, significantly reducing maintenance difficulty, shortening maintenance time, and minimizing equipment downtime.

[0090] At least two filter components are located on opposite sides of the housing 100.

[0091] This application also provides a vehicle, including a body and a transmission as described above disposed on the body.
