Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle parts technical field, especially a kind of filter housing structure, and simultaneously, the utility model further relates to a filter with the filter housing structure and vehicle. BACKGROUND

[0002] The filter in the prior art is used to filter oil, and for example, a suction filter has a filter part therein, and oil flowing into the oil inlet flows out through the oil outlet after being filtered by the filter part. Currently, the shell of some suction filters is immersed in oil. The suction filter on a vehicle is usually provided with one or two oil inlets and two oil outlets, one of which is connected to a lubricating oil circuit, and the other is connected to an actuating oil circuit. The lubricating oil circuit needs large flow to lubricate and cool the shaft tooth, and the actuating oil circuit builds pressure by using a small throttle hole to push the clutch to work. Due to its simple implementation and reliable function, it has become the mainstream transmission oil circuit system.

[0003] With the lightweight and integrated design of the transmission, the gear distance from the suction filter is relatively close, and the bottom of the gear is immersed in oil. When the transmission is running, a large amount of bubbles is generated by the oil stirring of the shaft tooth, and the bubbles can be sucked into the suction filter. The actuating oil circuit is sensitive to bubbles due to its high pressure and small flow. When the bubbles enter the actuating oil circuit and flow out from the throttle hole, a large pressure drop occurs in the actuating oil circuit, which affects the torque transmission of the clutch, thereby affecting the smoothness of the clutch torque transmission and further affecting the driving experience of the vehicle. SUMMARY

[0004] Therefore, the utility model aims to provide a filter housing structure to reduce the amount of bubbles flowing into the filter.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A filter housing structure includes a shell body having a filter cavity, an oil inlet is provided at the bottom of the shell body, and a flange is protruded downward along the edge of the oil inlet;

[0007] A bubble guide area is provided on the bottom wall of the shell body around the oil inlet, and the bubble guide area is set as an upward inclined surface in a direction away from the oil inlet to guide the bubbles in the oil to flow upward.

[0008] Further, a blocking ring is provided in the bubble guide area outside the flange, the blocking ring is arranged around the oil inlet, and the bottom end of the flange is lower than the bottom end of the blocking ring.

[0009] Further, an exhaust gap is provided on the blocking ring, and the bubbles inside the blocking ring can flow out through the gap.

[0010] Further, the filter cavity comprises two filter sub-cavities arranged in separation, and the oil inlet and the bubble guiding area are arranged one by one corresponding to the filter sub-cavities.

[0011] The shell body is provided with a gas guiding groove at the joint of the two bubble guiding areas, and the gas guiding groove is gradually inclined upward in the direction away from the oil inlet.

[0012] Further, the top of the shell body is provided with a convex portion, the top of the convex portion is provided with an oil outlet, and at least part of the side wall of the convex portion is configured as an inclined surface inclined to the oil outlet.

[0013] Further, the cross-sectional area of the convex portion gradually decreases in the direction pointing to the oil outlet.

[0014] Further, the cross-sectional area of the bubble guiding area gradually increases in the direction away from the oil inlet.

[0015] Further, the shell body comprises an upper shell and a lower shell connected by upper and lower buckling, and the filter cavity is defined between the upper shell and the lower shell.

[0016] The oil inlet and the bubble dispersing area are arranged on the lower shell.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] The oil filter shell structure has the following advantages: the oil inlet position is as low as possible due to the flange arranged in the lower convex manner at the bottom of the shell body, so that the amount of bubbles flowing into the oil inlet is reduced, the density of the bubbles in the oil is smaller than that of the oil itself, the bubble guiding area is arranged on the bottom wall of the shell body and is arranged as an inclined surface inclined upward in the direction away from the oil inlet, so that the bubbles are floated upward along the inclined surface and away from the oil inlet during the oil flow process, thereby reducing the amount of bubbles flowing into the filter cavity, the pressure fluctuation of the oil is reduced when the oil flows into the oil path, for example, the clutch torque transmission is more stable, thereby improving the driving stability of the vehicle.

[0019] Secondly, by setting a baffle ring around the oil inlet on the outside of the flange, air bubbles in the oil outside the baffle ring are prevented from entering the filter chamber. This also keeps the air bubbles between the flange and the baffle ring as far away from the oil inlet as possible, further reducing the amount of air bubbles flowing into the oil inlet. The bottom of the flange is lower than the bottom of the baffle ring, facilitating deeper oil intake and further reducing the amount of air bubbles flowing into the oil inlet. The venting notch on the baffle ring provides a discharge channel for air bubbles accumulating inside the baffle ring. When air bubbles rise to the inside of the baffle ring under the action of the inclined surface in the bubble guiding area, they can quickly flow out through the venting notch, shortening the residence time of air bubbles at the bottom of the shell body and accelerating the separation and discharge of air bubbles from the oil. This further helps to reduce the potential impact of air bubbles on the subsequent oil circuit system.

[0020] Furthermore, the dual-chamber design enhances the flexibility of the filter housing structure. The air guide groove formed at the junction of the two bubble-guiding areas, gradually sloping upwards away from the oil inlet, allows bubbles flowing upwards from the two bubble-guiding areas to enter the air guide groove and exit along its slope. This not only accelerates bubble discharge from the bottom of the housing but also prevents bubble accumulation at the junction of the two bubble-guiding areas, further improving the housing's ability to handle bubbles and reducing the amount of bubbles flowing into the oil inlet. The protruding portion, with the oil outlet located on it, facilitates implementation and improves oil discharge efficiency. The inclined surface disperses bubbles when the housing is tilted, preventing bubble aggregation and reducing the density of bubbles flowing out of the outlet, further enhancing vehicle stability.

[0021] Furthermore, the cross-sectional area of ​​the bubble guiding region gradually increases away from the oil inlet. This reduces the flow resistance of the oil around the bubbles, thus helping them rise faster and accelerating the separation of bubbles from the oil, allowing the bubbles to flow upward more smoothly. The design of the upper and lower shells forming the filter chamber facilitates layout and implementation, and the oil inlet and bubble dispersion area are located on the lower shell, resulting in better bubble separation performance.

[0022] In addition, another objective of this utility model is to provide an oil filter, including the housing structure described above.

[0023] The oil filter described in this utility model, by setting the oil filter housing structure as described above, helps to reduce the amount of air bubbles flowing into the filter chamber, thereby helping to increase the amount of air bubbles flowing into the execution oil circuit, thus helping to improve the driving smoothness of the vehicle.

[0024] Furthermore, this utility model also proposes a vehicle equipped with the oil filter described above.

[0025] The vehicle described in this utility model, by setting the oil filter as described above, overcomes the problem of excessive air bubbles entering the oil filter in the prior art, thereby improving the driving comfort of the vehicle. Attached Figure Description

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] This embodiment relates to an oil filter housing structure to reduce the amount of air bubbles flowing into the filter chamber.

[0051] In terms of overall structure, the oil filter housing structure of this embodiment includes a housing body P with a filtration chamber. The bottom of the housing body P is provided with an oil inlet and a flange 203 protruding downward along the edge of the oil inlet. The bottom wall of the housing body P is provided with a bubble guiding region 205 surrounding the oil inlet. The bubble guiding region 205 is configured as an upward inclined surface in a direction away from the oil inlet to guide bubbles in the oil to flow upward.

[0052] The oil filter housing structure described in this embodiment features a downwardly protruding flange 203 at the bottom of the housing body P, which lowers the oil inlet position as much as possible. Since there are fewer air bubbles at the bottom of the oil, this helps reduce the amount of air bubbles flowing into the oil inlet. Because the density of air bubbles in the oil is less than that of the oil itself, a bubble guiding area 205 is provided on the bottom wall of the housing body P. This bubble guiding area 205 is designed as an upward inclined surface away from the oil inlet. During the oil flow, the air bubbles will be buoyed and flow upward along the inclined surface away from the oil inlet, thus reducing the amount of air bubbles flowing into the filter chamber. When the oil flows into the oil circuit, such as the actuator circuit, it can reduce the pressure fluctuation of the oil, making the clutch torque transmission smoother, thereby improving the driving stability of the vehicle.

[0053] Based on the above overview, an exemplary structure of the oil filter housing described in this embodiment is as follows: Figures 1 to 4 As shown in the image.

[0054] To facilitate the explanation of the oil filter housing structure, we will take its application in a suction filter as an example. In this case, the entire housing body P is immersed in the oil inside the transmission housing and is fixed to the transmission housing. The fixing method of the housing body P can refer to existing technology and will not be repeated here. As a preferred embodiment, such as... Figure 4 As shown, the cross-sectional area of ​​the bubble guiding region 205 gradually increases in the direction away from the oil inlet. This arrangement reduces the flow resistance of the oil around the bubble, which helps the bubble rise faster, thereby accelerating the separation speed between the bubble and the oil and allowing the bubble to flow upward more smoothly.

[0055] To distinguish it from the inclined surface provided on the protruding portion 103 described below, the inclined surface in the bubble guiding region 205 will be referred to as the first inclined surface 2051, and the inclined surface on the protruding portion 103 will be referred to as the second inclined surface 104. In this embodiment, an exemplary structure of the bubble guiding region 205 is as follows: Figure 2 and Figure 4As shown, it has four first inclined surfaces 2051 arranged sequentially in the circumferential direction of the oil inlet. Two of the first inclined surfaces 2051 are arranged opposite each other in the length direction of the shell body P, and the other two first inclined surfaces 2051 are arranged opposite each other in the width direction of the shell body P.

[0056] By setting four first inclined surfaces 2051, the bottom of the shell body P is made into a pyramidal shape. This facilitates the layout and implementation, and provides a better bubble guiding effect. Of course, the number of first inclined surfaces 2051 can be increased or decreased according to the usage requirements. Furthermore, in addition to being pyramidal, the bottom of the shell body P can also be conical, which can be determined according to the usage requirements during the specific implementation.

[0057] In this embodiment, the first inclined surface 2051 is designed so that the component force along the inclined surface when the bubble rises can be used to make the bubble flow in all directions and move away from the oil inlet. By utilizing the characteristic of the bubble rising, the buoyancy of the bubble can generate a component force along the tilt direction of the first inclined surface 2051. This component force is greater than the flow resistance of the oil and drives the bubble to move away from the oil inlet continuously.

[0058] Furthermore, the gradually increasing cross-sectional area of ​​the bubble guiding region 205 away from the oil inlet provides ample space for the bubbles to rise. As the bubbles move upward, their surrounding cross-sectional area gradually increases, giving them more opportunities to merge. Larger bubbles rise faster under buoyancy and are more likely to break through the oil layer and be discharged upward. Therefore, the gradually increasing cross-sectional area of ​​the bubble guiding region 205 allows the bubbles to continuously merge and aggregate during their ascent, enhancing the separation effect from the oil. Compared to a case with a constant cross-sectional area, this method more effectively removes bubbles from the oil, thereby reducing the amount of bubbles flowing into the oil filter.

[0059] In a preferred embodiment, the filter chamber includes two separate filter compartments, with an oil inlet and a bubble guiding area 205 corresponding to each filter compartment. The housing P has an air guide groove 206 located at the junction of the two bubble guiding areas 205, gradually sloping upwards away from the oil inlet. This arrangement of two filter compartments improves the flexibility of the filter housing structure. The air guide groove 206 formed at the junction of the two bubble guiding areas 205, and its gradual upward sloping away from the oil inlet, allows bubbles to flow upwards from the two bubble guiding areas 205 to the junction, where they can smoothly enter the air guide groove 206 and be discharged along its sloping direction. This not only accelerates the discharge of bubbles from the bottom of the housing P but also prevents bubbles from accumulating at the junction of the two bubble guiding areas 205, further enhancing the bubble handling capacity of the bottom of the housing P and reducing the amount of bubbles flowing into the oil inlet.

[0060] In terms of specific structure, such as Figure 2 and Figure 4 As shown, for ease of distinction, one of the filtering chambers is designated as the first filtering chamber M, and the oil inlet connected to the bottom of the first filtering chamber M is designated as the first oil inlet 201. The other filtering chamber is designated as the second filtering chamber N, and the oil inlet connected to the bottom of the second filtering chamber N is designated as the second oil inlet 202. The first filtering chamber M can be connected to the vehicle's actuator oil circuit to deliver the filtered oil to the clutch. The actuator oil circuit specifically utilizes a small throttle orifice to build pressure and drive the clutch. The second filtering chamber N is connected to the vehicle's lubrication oil circuit to deliver the filtered oil to the shaft gears for lubrication and cooling.

[0061] In this embodiment, by setting bubble guiding regions 205 corresponding one-to-one with the first oil inlet 201 and the second oil inlet 202, the amount of bubbles flowing into the oil in both inlets is reduced. This not only overcomes the problem in the prior art where the amount of bubbles flowing into the actuator oil circuit is too large, the flow velocity of the gas exiting the throttle orifice is much greater than that of the oil, and the speed at which large bubbles exit the throttle orifice is too fast, far exceeding the feedback adjustment speed of the actuator pump, causing a sudden drop in the actuator oil circuit pressure and affecting the transmission of clutch torque, but also improves the driving comfort of the vehicle. In addition, by reducing the amount of bubbles flowing into the lubrication oil circuit, the problem of excessive noise caused by a large amount of bubbles in the lubrication oil circuit is solved, which also helps to improve the driving comfort of the vehicle.

[0062] like Figure 2 As shown, the first oil inlet 201 and the second oil inlet 202 are spaced apart along the length of the housing body P. The area of ​​the first oil inlet 201 is smaller than the area of ​​the second oil inlet 202 to simultaneously meet the lubrication and cooling requirements of the clutch and components. Two first inclined surfaces 2051 located between the first oil inlet 201 and the second oil inlet 202 intersect to define the aforementioned air guide groove 206, the cross-section of which is a downward-opening "V" shape. (Refer to...) Figure 8 and Figure 9 As shown, along the direction away from the oil inlet, the air guide groove 206 gradually tilts upward so that the air bubbles entering the air guide groove 206 can continue to flow upward along the air guide groove 206, thereby making the air bubbles away from each oil inlet, effectively reducing the number of air bubbles entering the suction filter, reducing the noise of the lubricating oil circuit, and reducing the pressure drop of the actuating oil circuit.

[0063] As a preferred implementation method, such as Figure 2 and Figure 7As shown, a blocking ring 204 is provided in the bubble guiding area 205 outside the flange 203. The blocking ring 204 is arranged around the oil inlet, and the bottom end of the flange 203 is lower than the bottom end of the blocking ring 204. By setting the blocking ring 204 outside the flange 203, it is beneficial to prevent bubbles in the oil outside the blocking ring 204 from entering the filter chamber, and to keep the bubbles between the flange 203 and the blocking ring 204 as far away from the oil inlet as possible, further reducing the amount of bubbles flowing into the oil inlet. Making the bottom end of the flange 203 lower than the bottom end of the blocking ring 204 is beneficial to achieve deep oil intake (the oil in the deep part has less bubble content), and also helps to reduce the amount of bubbles flowing into the oil inlet. Moreover, because the negative pressure at the oil inlet is large, even if a small number of bubbles enter between the blocking ring 204 and the flange 203, it can further prevent the bubbles from flowing into the oil inlet. Furthermore, even if bubbles cross the blocking ring 204, they can be blocked by the flange 203, preventing the bubbles from being carried into the filter chamber by the negative pressure of the oil.

[0064] In a preferred embodiment, the baffle ring 204 is provided with an exhaust notch 2041, through which air bubbles inside the baffle ring 204 can flow out. This exhaust notch 2041 on the baffle ring 204 provides a discharge channel for air bubbles accumulating inside the baffle ring 204. When air bubbles rise to the inside of the baffle ring 204 under the action of the first inclined surface 2051 of the bubble guiding area 205, they can quickly flow out through the exhaust notch 2041, thus shortening the residence time of air bubbles at the bottom of the shell body P, accelerating the separation and discharge of air bubbles from the oil, and further reducing the potential impact of air bubbles on the subsequent oil circuit system. Furthermore, the exhaust notch 2041 on the baffle ring 204 allows air bubbles accumulating inside the baffle ring 204 to be discharged smoothly, preventing the accumulated air bubbles from being sucked into the filter under inclined conditions.

[0065] In this embodiment, a blocking ring 204 and an exhaust notch 2041 are provided on the outer side of each flange 203 to further reduce the amount of air bubbles in the oil flowing into the first filter chamber M and the second filter chamber N. It is understood that a blocking ring 204 can also be provided on the outer side of only one flange 203. In this case, the blocking ring 204 specifically corresponds to the first oil inlet 201, because the oil passage is more sensitive to air bubbles. Furthermore, in this embodiment, the orientation of the exhaust notch 2041 should avoid facing the left and right sides of the housing body P as much as possible to ensure the exhaust effect when the housing body P is tilted left or right.

[0066] As a preferred implementation method, such as Figure 2 and Figure 4As shown, the top of the shell body P is provided with a protruding portion 103, and the top of the protruding portion 103 is provided with an oil outlet. At least a portion of the sidewall of the protruding portion 103 is configured as a second inclined surface 104 inclined towards the oil outlet. By providing the protruding portion 103 and setting the oil outlet on the protruding portion 103, it is convenient to arrange and implement, and improves the oil delivery effect. By providing the second inclined surface 104, it is beneficial to disperse the air bubbles at the top of the filter chamber when the shell body P is tilted, prevent the accumulation of air bubbles, thereby preventing the formation of large air bubbles due to air bubble accumulation, and reducing the density of air bubbles flowing out of the oil outlet, which further helps to improve the stability of vehicle driving.

[0067] Furthermore, after being filtered through the filter chamber, the oil enters the top area of ​​the housing P. The inclined second slope 104 acts like a guide vane, allowing the oil to naturally converge towards the outlet along the inclined direction of the second slope 104 using gravity and fluid dynamics principles. This guiding effect prevents disordered oil flow in the top area, reduces oil residue in the housing, and improves the efficiency of oil flowing out of the filter. Without the protruding part 103 and the inclined second slope 104, when the housing P is tilted, air bubbles tend to concentrate and coalesce into large bubbles. These large bubbles, when the housing P becomes horizontal, flow into the actuator oil circuit, affecting the smoothness of vehicle driving; if they flow into the lubrication oil circuit, they will cause noise.

[0068] The inclined second slope 104 not only guides the oil flow towards the outlet but also accelerates it. As the oil converges towards the outlet, its flow rate gradually increases, creating a relatively stable pressure at the outlet. This stable outlet pressure helps ensure a stable oil supply in the subsequent hydraulic circuit, preventing unstable clutch torque transmission due to outlet pressure fluctuations, thereby improving the smoothness of the overall vehicle driving experience.

[0069] It should be noted that even if small air bubbles enter the suction filter, they will not accumulate at the second inclined plane 104. The small air bubbles directly enter the actuation oil circuit and do not affect the torque transmission of the clutch. This is because a single large air bubble causes a large pressure drop when passing through the throttle orifice, while a series of small air bubbles passing through the throttle orifice in sequence generate multiple small pressure drops. These small pressure drops are absorbed by the safety pressure margin of the clutch, thus not affecting the clutch engagement and torque transmission.

[0070] Combination Figure 1 , Figures 10 to 12As shown, the oil outlet communicating with the first filter chamber M is called the first oil outlet 101, and the oil outlet communicating with the second filter chamber N is called the second oil outlet 102. The protruding portion 103 is located at the top of the first filter chamber M, and the first oil outlet 101 is located at one end of the protruding portion 103 and protrudes outwards. The second oil outlet 102 is also located facing the housing body P, and its extension direction is the same as that of the first oil outlet 101. The second inclined surfaces 104 corresponding to the first oil outlet 101 are preferably located on the left and right sides of the first oil outlet 101, and on the side opposite to the first oil outlet 101. Through the cooperation of the three second inclined surfaces 104, the problem of bubbles easily accumulating and forming large bubbles when the housing body P is tilted is effectively solved. The second inclined surfaces 104 can disperse the bubbles and prevent them from accumulating, thereby reducing the amount of bubbles flowing out of the oil filter.

[0071] In this embodiment, the cross-sectional area of ​​the protruding portion 103 gradually decreases along the direction pointing towards the oil outlet. By providing the protruding portion 103 and placing the oil outlet on it, the arrangement is facilitated and the oil delivery effect is improved. The second inclined surface 104 helps disperse air bubbles when the shell body P is tilted, preventing bubble aggregation and thus reducing the density of air bubbles flowing out of the oil outlet, further improving the vehicle's driving stability. Of course, one second inclined surface 104 can be provided corresponding to the second filter chamber N, or multiple second inclined surfaces 104 can be provided according to usage requirements, as long as the usage needs are met.

[0072] In a preferred embodiment, the shell body P includes an upper shell 1 and a lower shell 2 that are interlocked and connected, with a filter chamber defined between the upper shell 1 and the lower shell 2; the oil inlet and the bubble dispersion area are located on the lower shell 2. This arrangement, in which the upper shell 1 and the lower shell 2 cooperate to form the filter chamber, is easy to implement, and the location of the oil inlet and the bubble dispersion area on the lower shell 2 provides a better bubble separation effect.

[0073] In terms of specific structure, such as Figure 3 and Figure 4 As shown, to facilitate the connection between the upper housing 1 and the lower housing 2, an upper flange 105 and a lower flange 207 are respectively provided on the edges of the two. In specific connection, a sealing gasket 5 can be provided between the upper flange 105 and the lower flange 207 to improve the sealing effect of the housing body P. By providing multiple connectors passing through the upper flange 105, the sealing gasket 5, and the lower flange 207, the three are fixed together.

[0074] An upwardly protruding upper protrusion 2071 is provided on the edge of the lower flange 207, and the upper protrusion 2071 and the lower flange 207 together form a mounting groove for placing the sealing gasket 5. Further, as... Figure 6As shown, in order to improve structural strength, reinforcing grooves 208 extending along the width direction of the shell body P are provided on the upper flange 105 and lower flange 207 corresponding to the first filter chamber M, and multiple reinforcing ribs 2081 are provided at intervals in the reinforcing grooves 208.

[0075] To separate the first filter chamber M from the second filter chamber, two lower partitions 209 are provided inside the lower housing 2, and two upper partitions 109 are provided inside the upper housing 1, corresponding one-to-one with the two lower partitions 209. When engaged, the upper partitions 109 and lower partitions 209 cooperate to separate the two filter chambers. Alternatively, a sealing structure can be provided between the upper partitions 109 and lower partitions 209 to ensure a proper seal. Furthermore, the separation structure separating the first filter chamber M and the second filter chamber N can also refer to existing technologies.

[0076] In addition, such as Figure 10 and Figure 11 As shown, a mounting structure for fixing the magnet 6 can also be provided on the upper housing 1. This mounting structure includes two spaced-apart support ribs 106, two first limiting ribs 107 corresponding to one end of each support rib 106, and two second limiting ribs 108 on both sides of the two support ribs 106. Both the first limiting ribs 107 and the second limiting ribs 108 are in the shape of a "7". The displacement of the magnet 6 is restricted by the contact between the first limiting ribs 107 and the end face and top surface of the magnet 6, and the displacement of the magnet 6 is further restricted by the contact between the second limiting ribs 108 and the side face of the magnet 6. In this embodiment, the support ribs 106, the first limiting ribs 107, and the second limiting ribs 108 together define the mounting space for the magnet 6.

[0077] Furthermore, two second limiting ribs 108 are spaced apart along the length of the support rib 106. One of the second limiting ribs 108 extends laterally to the other side, and a limiting protrusion 1081 is provided on this second limiting rib 108. The limiting protrusion 1081 blocks one side of the end of the magnet 6, preventing the magnet 6 from detaching from the installation space. Moreover, by providing the support rib 106, the contact area between the magnet 6 and the oil is increased, thereby improving the adsorption efficiency of the magnet 6. Of course, in specific implementations, the number and position of the installation structure can be adaptively adjusted according to usage requirements.

[0078] It should be noted that the number of oil inlets in this embodiment can be adjusted according to needs. For example, only one oil inlet and one oil outlet can be set. In this case, the amount of air bubbles flowing into the filter chamber can be reduced, and the driving comfort of the vehicle can still be improved after the oil flows into the actuator oil circuit.

[0079] In this embodiment, when the shell body P is in a horizontal state, the flow path of the bubble at the bottom of the shell body P is as follows:Figure 13 As shown in the diagram, the bubbles all flow upwards along the corresponding first inclined surface 2051, and the bubbles flowing into the air guide groove 206 flow from the lower end to the higher end, thereby moving the bubbles away from the first oil inlet 201 and the second oil inlet 202, thus reducing the amount of bubbles flowing into the oil in the filter chamber.

[0080] When the shell body P is tilted to the right, the flow path of the bubble at the bottom of the shell body P is as follows: Figure 14 As shown in the diagram, bubbles located near the first oil inlet 201 flow to the right along the first inclined surface 2051, and after being blocked by the blocking ring 204, their flow path changes, flowing upwards and to the right. Bubbles flowing into the air guide groove 206 are guided upwards. Bubbles located near the second oil inlet 202 also flow upwards under the guidance of the corresponding first inclined surface 2051, thereby reducing the amount of bubbles in the oil flowing into the filter chamber. When the shell body P is in a left-tilted, uphill, or downhill state, the bubble guiding area 205 can keep the bubbles away from the oil inlet.

[0081] The oil filter housing in this embodiment, through structural improvements to the housing body P, effectively solves the problem of air bubble noise in the lubrication circuit by reducing air bubbles entering the oil inlet and preventing air bubble accumulation, thus improving user driving comfort. It also effectively solves the problem of pressure drop in the actuator oil circuit, improving the smoothness of clutch torque transmission. This oil filter housing also enhances the vehicle's off-road capabilities, preventing pressure drop in the actuator oil circuit even under steep tilt conditions, reducing oil pressure fluctuations, maintaining smooth clutch engagement, and ensuring continuous power output, thereby improving vehicle driving safety.

[0082] Example 2

[0083] This embodiment relates to an oil filter, including the housing structure in Embodiment 1.

[0084] Reference Figures 3 to 5 As shown, a first filter element 3 is provided in the first filter chamber M, and a second filter element 4 is provided in the second filter chamber N. Oil flowing in through the first oil inlet 201 is filtered by the first filter element 3 and flows out through the first oil outlet 101, then into the actuation oil circuit. Oil flowing in through the second oil inlet 202 is filtered by the second filter element 4 and flows out through the second oil outlet 102, then into the lubrication oil circuit. The structure and installation method of the first filter element 3 and the second filter element 4 can refer to existing technology.

[0085] The oil filter in this embodiment, by setting the oil filter housing structure as described above, helps to reduce the amount of air bubbles flowing into the filter chamber, thereby helping to increase the amount of air bubbles flowing into the actuator oil circuit, thus helping to improve the driving smoothness of the vehicle.

[0087] This embodiment relates to a vehicle equipped with the oil filter described in Embodiment 2.

[0088] The vehicle in this embodiment, by setting the oil filter as described above, helps to overcome the problem of excessive air bubbles entering the oil filter in the prior art, thereby improving the driving comfort of the vehicle.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
