Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a novel suction filter. Background Technology

[0002] The suction filter is fixed to the transmission housing. Its inlet is immersed in the transmission fluid, and its outlet is connected to the oil pump. The negative pressure generated by the oil pump draws in oil, which is then filtered through the filter paper in the suction filter before entering the oil pump. The filtered oil contains fewer impurities, which helps extend the life of the oil pump.

[0003] Chinese Utility Model Patent Publication No. CN 223105222 U discloses a novel suction filter. The specification of this novel suction filter states that by placing both the oil filter chamber and the oil outlet chamber on the left side of the main body and connecting them to the oil filter chamber via an oil inlet channel within the flat section, it can meet oil inlet requirements and adapt to specific installation spaces. However, this novel suction filter does not have two separate sealed cavities. When a car requires two oil pumps, the suction filter needs two oil outlets. When a single oil outlet operates independently, it will cause air suction (air is sucked in during oil suction), resulting in noise. Furthermore, the lack of a magnet prevents the suction of ferromagnetic impurities in the oil, leading to filter paper clogging and requiring frequent filter paper replacements, thus reducing its practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a novel suction filter that can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a novel suction filter, including a gearbox housing and a suction filter body located inside the gearbox housing. The suction filter body includes an upper housing assembly and a lower housing assembly. Filter paper is disposed between the upper housing assembly and the lower housing assembly. A fixing seat is fixedly installed at the end of the upper housing assembly away from the lower housing assembly. A bushing is embedded in the inner surface of the fixing seat.

[0006] The upper housing assembly includes a first upper cavity and a second upper cavity, and both the first upper cavity and the second upper cavity are fixedly mounted with annularly distributed protrusions at the end near the lower housing assembly.

[0007] The lower housing assembly includes a first lower cavity and a second lower cavity, and the first lower cavity and the second lower cavity have annularly distributed slots at one end near the upper housing assembly.

[0008] Preferably, the upper housing assembly further includes an EOP oil outlet, an MOP oil outlet, a first sealing ring, and a second sealing ring. The EOP oil outlet is provided on the top side of the first upper cavity away from the fixed seat, and the MOP oil outlet is provided on the top side of the second upper cavity away from the fixed seat.

[0009] Preferably, a first sealing ring is embedded in the outer surface of the EOP oil outlet, and a second sealing ring is embedded in the outer surface of the MOP oil outlet.

[0010] The above technical solution enhances the sealing between the oil outlet and the external pipeline by embedding a first sealing ring on the outer surface of the EOP oil outlet and a second sealing ring on the outer surface of the MOP oil outlet, thus preventing oil leakage during transportation.

[0011] Preferably, the lower housing assembly further includes a locking screw, a guide plate, an EOP oil inlet, and an MOP oil inlet. The guide plate is fixedly installed at the end of the first lower cavity and the second lower cavity near the upper housing assembly. An EOP oil inlet is provided at the end of the first lower cavity away from the upper housing assembly, and an MOP oil inlet is provided at the end of the second lower cavity away from the upper housing assembly.

[0012] By using the above technical solution, and by setting baffles inside the first and second lower cavities, the oil can be guided and buffered as it enters the cavity from the EOP and MOP inlets, allowing the oil to pass through the filter paper more smoothly and flow out from the EOP and MOP outlets respectively. This ensures that the oil in different oil paths can complete the filtration process independently, thereby improving filtration efficiency.

[0013] Preferably, the first upper cavity and the second upper cavity are connected by welding, and the first lower cavity and the second lower cavity are connected by welding. The upper housing assembly and the lower housing assembly together form the filter body.

[0014] Through the above technical solution, by welding the first upper cavity and the second upper cavity together, and by welding the first lower cavity and the second lower cavity together, the filter body can be effectively divided into two separate closed spaces, allowing the EOP oil outlet and the MOP oil outlet to work independently. The welding connection improves the sealing of the two closed spaces, preventing air suction when the EOP operates alone, thus preventing noise.

[0015] Preferably, the cross-section of the protrusion is the same as the cross-section of the slot, the upper housing assembly and the lower housing assembly are snap-fitted together, and locking screws are provided on the side of the first lower cavity and the second lower cavity away from the upper housing assembly. Multiple sets of the locking screws are provided, and the multiple sets of locking screws are located on the lower surface of the first lower cavity and the second lower cavity in a ring distribution. The locking screws penetrate the first lower cavity and the second lower cavity and extend into the interior of the first upper cavity and the second upper cavity.

[0016] The above technical solution, with its snap-fit ​​design for the upper and lower housing components, facilitates quick docking and installation. Multiple sets of annularly distributed locking screws penetrate the first and second lower cavities and extend into the first and second upper cavities, enhancing the connection strength between the upper and lower housing components. This also ensures that the filter paper is tightly clamped, guaranteeing the filtration effect.

[0017] Preferably, a mounting plate is fixedly installed at the end of the lower housing assembly away from the upper housing assembly, and a magnet is snapped onto the inner surface of the mounting plate.

[0018] The above technical solution effectively adsorbs ferromagnetic impurities in the oil by setting up a magnet, reducing filter paper clogging and increasing the service life of the suction filter. Furthermore, the magnet can be detached by snapping it onto the mounting plate, facilitating future maintenance and replacement.

[0019] Compared with the prior art, the present invention provides a novel suction filter with the following beneficial effects:

[0020] 1. This novel suction filter, through the welding connection between the first upper chamber and the second upper chamber and the welding connection between the first lower chamber and the second lower chamber, effectively divides the internal body of the suction filter into two separate closed spaces, allowing the EOP oil outlet and the MOP oil outlet to work independently. The welding connection improves the sealing of the two closed spaces, preventing air suction when the EOP operates alone, thus preventing noise.

[0021] 2. This new type of suction filter, through the snap-fit ​​design of the upper and lower housing components, facilitates quick docking and installation of the upper and lower housing components. Multiple sets of ring-shaped locking screws penetrate the first and second lower cavities and extend into the first and second upper cavities, enhancing the connection strength between the upper and lower housing components. At the same time, it also ensures that the filter paper is tightly clamped, guaranteeing the filtration effect.

[0022] 3. This new type of suction filter, by setting up a magnet, can effectively adsorb ferromagnetic impurities contained in the oil, reduce filter paper clogging, increase the service life of the suction filter, and achieve detachable installation of the magnet by snapping the magnet to the mounting plate, which is convenient for later maintenance and replacement.

[0030] 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.

[0031] Example 1: As Figure 1-6 As shown, the present invention provides a novel suction filter, including a gearbox housing 1 and a suction filter body 2 located inside the gearbox housing 1. The suction filter body 2 includes an upper housing assembly 3 and a lower housing assembly 4. A filter paper 5 is disposed between the upper housing assembly 3 and the lower housing assembly 4. A fixing seat 6 is fixedly installed at the end of the upper housing assembly 3 away from the lower housing assembly 4. A bushing 7 is embedded in the inner surface of the fixing seat 6.

[0032] The upper housing assembly 3 includes a first upper cavity 301 and a second upper cavity 302. Both the first upper cavity 301 and the second upper cavity 302 are fixedly installed with annularly distributed protrusions 303 at one end near the lower housing assembly 4.

[0033] The lower housing assembly 4 includes a first lower cavity 401 and a second lower cavity 402. The first lower cavity 401 and the second lower cavity 402 are provided with annularly distributed slots 403 at one end near the upper housing assembly 3.

[0034] Specifically, the upper housing assembly 3 also includes an EOP oil outlet 304, an MOP oil outlet 305, a first sealing ring 306, and a second sealing ring 307. The EOP oil outlet 304 is provided on the side of the top of the first upper cavity 301 away from the fixed base 6, and the MOP oil outlet 305 is provided on the side of the top of the second upper cavity 302 away from the fixed base 6.

[0035] Specifically, a first sealing ring 306 is embedded in the outer surface of the EOP oil outlet 304, and a second sealing ring 307 is embedded in the outer surface of the MOP oil outlet 305. The advantage is that by embedding the first sealing ring 306 in the outer surface of the EOP oil outlet 304 and the second sealing ring 307 in the outer surface of the MOP oil outlet 305, the sealing between the oil outlet and the external pipeline is enhanced, preventing oil leakage during transportation.

[0036] Specifically, the lower housing assembly 4 also includes a locking screw 404, a guide plate 405, an EOP inlet 406, and an MOP inlet 407. Guide plates 405 are fixedly installed at the ends of the first lower cavity 401 and the second lower cavity 402 closest to the upper housing assembly 3. The EOP inlet 406 is located at the end of the first lower cavity 401 furthest from the upper housing assembly 3, and the MOP inlet 407 is located at the end of the second lower cavity 402 furthest from the upper housing assembly 3. The advantage is that by providing guide plates 405 inside the first lower cavity 401 and the second lower cavity 402, the oil can be guided and buffered as it enters the cavity from the EOP inlet 406 and the MOP inlet 407, allowing the oil to pass through the filter paper 5 more smoothly and flow out from the EOP outlet 304 and the MOP outlet 305 respectively. This ensures that the oil in different oil paths can complete the filtration process independently, improving filtration efficiency.

[0037] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the first upper cavity 301 and the second upper cavity 302 are connected by welding, and the first lower cavity 401 and the second lower cavity 402 are connected by welding. The upper housing assembly 3 and the lower housing assembly 4 together form the filter body 2. The advantage is that by connecting the first upper cavity 301 and the second upper cavity 302 and the first lower cavity 401 and the second lower cavity 402 by welding, the internal space of the filter body 2 can be effectively divided into two separate enclosed spaces, allowing the EOP oil outlet 304 and the MOP oil outlet 305 to operate independently. The welding connection improves the sealing of the two enclosed spaces, preventing air suction when the EOP operates alone, thus preventing noise.

[0039] Specifically, the cross-section of the protrusion 303 is the same as the cross-section of the slot 403. The upper housing assembly 3 and the lower housing assembly 4 are snap-fitted together. Locking screws 404 are provided on the side of the first lower cavity 401 and the second lower cavity 402 away from the upper housing assembly 3. Multiple sets of locking screws 404 are provided. The multiple sets of locking screws 404 are located on the lower surface of the first lower cavity 401 and the second lower cavity 402 and are distributed in a ring. The locking screws 404 penetrate the first lower cavity 401 and the second lower cavity 402 and extend into the interior of the first upper cavity 301 and the second upper cavity 302. The advantage is that the snap-fit ​​design of the upper housing assembly 3 and the lower housing assembly 4 facilitates quick docking and installation. The multiple sets of ring-shaped locking screws 404 penetrate the first lower cavity 401 and the second lower cavity 402 and extend into the first upper cavity 301 and the second upper cavity 302, which enhances the connection strength between the upper housing assembly 3 and the lower housing assembly 4. At the same time, it can also ensure that the filter paper 5 is tightly clamped and guarantee the filtration effect.

[0040] Specifically, a mounting plate 8 is fixedly installed at the end of the lower housing assembly 4 away from the upper housing assembly 3, and a magnet 9 is snapped onto the inner surface of the mounting plate 8. The advantage is that by setting the magnet 9, ferromagnetic impurities contained in the oil can be effectively adsorbed, reducing the clogging of the filter paper 5 and increasing the service life of the suction filter. Furthermore, the snap-fit ​​installation of the magnet 9 onto the mounting plate 8 allows for detachable installation of the magnet 9, facilitating later maintenance and replacement.

[0041] Working Principle: During use, the upper housing assembly 3 and the lower housing assembly 4 are designed for snap-fit ​​installation, facilitating quick and easy connection. Multiple sets of annularly distributed locking screws 404 penetrate the first lower cavity 401 and the second lower cavity 402, extending into the first upper cavity 301 and the second upper cavity 302, enhancing the connection strength between the upper housing assembly 3 and the lower housing assembly 4. This also ensures that the filter paper 5 is tightly clamped, guaranteeing filtration efficiency. The guide plates 405 installed inside the first lower cavity 401 and the second lower cavity 402 guide and buffer the oil entering the cavity from the EOP inlet 406 and the MOP inlet 407, allowing the oil to pass through the filter paper 5 more smoothly and flow out from the EOP outlet 304 and the MOP outlet 305 respectively. This ensures that the oil in different oil paths can complete the filtration process independently, improving filtration efficiency. A first sealing ring 306 is embedded in the outer surface of the EOP outlet 304. A second sealing ring 307 is embedded in the outer surface of the MOP oil outlet 305, which enhances the sealing between the oil outlet and the external pipeline and prevents oil leakage during transportation. The first upper cavity 301 and the second upper cavity 302 are connected by welding, and the first lower cavity 401 and the second lower cavity 402 are connected by welding. This effectively divides the internal part of the filter body 2 into two separate closed spaces, allowing the EOP oil outlet 304 and the MOP oil outlet 305 to work independently. The welding connection improves the sealing of the two closed spaces and prevents the EOP from sucking air when it operates alone, thus preventing noise. The magnet 9 can effectively adsorb ferromagnetic impurities in the oil, reduce the clogging of the filter paper 5, and increase the service life of the filter. The magnet 9 can be detached and installed by snapping it onto the mounting plate 8, which is convenient for later maintenance and replacement. The filter body 2 is fixed to the gearbox housing 1 by screws at the bushing 7.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
