Description

Technical Field

[0001] This utility model relates to the field of transmission cooling oil pipe technology, and in particular to a transmission cooling oil pipe anti-clogging device. Background Technology

[0002] Transmission cooling hoses are key components in a vehicle's transmission system responsible for transporting and cooling transmission fluid. They are typically made of high-temperature, high-pressure resistant metal or rubber tubing, connecting the transmission to the cooler to form a closed-loop oil circulation circuit. Their core function is to reduce the transmission fluid temperature through heat exchange, ensuring stable operation of the transmission system under high-temperature conditions.

[0003] Especially the metal cooling pipes, which are usually oil inlets, lead out from the transmission oil outlet and deliver high-temperature oil to the cooler. Because wear inside the transmission produces metal impurities (such as clutch disc debris, gear wear residue, etc.), a multi-layer filter structure needs to be installed inside the oil inlet pipe to prevent these impurities from clogging it, effectively reducing the chance of the cooling oil pipe becoming blocked.

[0004] However, in actual use, due to the overlapping and flat mesh structure of the multi-layer filter, a large number of filter screens will reduce the size of the internal channel of the oil pipe. When a large number of impurities are attached to the filter screen and cause the mesh to be blocked, it will easily hinder the flow of hot oil and significantly reduce the anti-clogging performance of the cooling oil pipe. Therefore, we propose a gearbox cooling oil pipe anti-clogging device that can not hinder the flow of hot oil and improve the anti-clogging performance. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the multi-layer filter structure can easily obstruct the flow of hot oil, and to propose a gearbox cooling oil pipe anti-clogging device that can improve the anti-clogging performance without obstructing the flow of hot oil.

[0006] The technical solution of this utility model: A gearbox cooling oil pipe anti-clogging device, comprising a filter pipe, one end of which is fixedly installed with a connecting pipe, and further comprising:

[0007] A corrugated filter box is inserted inside a filter tube. Several corrugated filter plates arranged at equal intervals are fixedly installed inside the corrugated filter box. The corrugated filter plates are used to adsorb impurities in hot oil.

[0009] Optionally, the corrugated filter box has a rubber sealing frame at the top opening, the rubber sealing frame is tightly pressed against the top of several corrugated filter plates, and the lower surface of the annular pressure plate is in close contact with the rubber sealing frame.

[0010] Optionally, an oil drain channel is provided between two adjacent corrugated filter plates. A plurality of first polyester fiber meltblown fabrics are fixedly installed on one side of the corrugated filter plate, and a plurality of second polyester fiber meltblown fabrics are fixedly installed on the other side of the corrugated filter plate.

[0011] Optionally, a number of built-in support plates are fixedly installed on the inner wall of the filter tube, the top outer wall of the corrugated filter box is tightly clamped between the number of built-in support plates, and the lower surface of the annular pressure plate is in close contact with the upper surface of the number of built-in support plates.

[0012] Optionally, a number of fixing bolts are provided on the annular pressure plate, and the threaded ends of the fixing bolts all pass through the annular pressure plate and are threadedly connected to the matching built-in support plate.

[0013] Optionally, the end of the filter tube away from the connecting tube is provided with a first connector, and the end of the connecting tube away from the filter tube is provided with a second connector. Both the first connector and the second connector are fitted with annular rubber rings.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figures 1-3 As shown, this utility model proposes a transmission cooling oil pipe anti-clogging device, including a filter pipe 1. A connecting pipe 5 is fixedly installed at one end of the filter pipe 1. A circular oil outlet 11 is cut at the end of the filter pipe 1 near the connecting pipe 5. One end of the connecting pipe 5 covers the outside of the circular oil outlet 11 to ensure that the hot oil inside the filter pipe 1 can be discharged into the connecting pipe 5, which facilitates the discharge of the hot oil inside the transmission into the cooler. A corrugated filter box 2 is movably inserted inside the filter pipe 1. Several corrugated filter plates 21 arranged at equal intervals are fixedly installed inside the corrugated filter box 2. When the heat... When oil passes through the corrugated filter box 2, the corrugated filter plate 21 adsorbs the metal impurities in the hot oil, preventing the impurities from entering the cooler along the connecting pipe 5, effectively improving the anti-clogging effect. An annular pressure plate 3 is fixedly installed inside the filter pipe 1. After the corrugated filter box 2 is installed inside the filter pipe 1, the annular pressure plate 3 presses and positions the top of the corrugated filter box 2, which not only ensures that the corrugated filter box 2 is firmly installed inside the filter pipe 1, but also allows the corrugated filter box 2 to be disassembled by removing the annular pressure plate 3, making it convenient to clean and maintain the impurities inside.

[0029] like Figures 1-4 As shown, in order to prevent the filter structure from obstructing the flow of hot oil, an oil drain channel 211 is provided between two adjacent corrugated filter plates 21. The hot oil discharged from the gearbox enters the oil drain channel 211 and then enters the connecting pipe 5 along the oil drain channel 211. The spacing of the oil drain channels 211 is large, so even if there are metal impurities attached to the surface of the corrugated filter plate 21, it will not affect the flow of hot oil, effectively reducing the probability of obstructing the flow of hot oil.

[0030] Furthermore, to improve the filtration effect of the corrugated filter plate 21, several first polyester fiber meltblown cloths 212 are fixedly installed on one side of the corrugated filter plate 21, and several second polyester fiber meltblown cloths 213 are fixedly installed on the other side of the corrugated filter plate 21. The first polyester fiber meltblown cloths 212 and the matching second polyester fiber meltblown cloths 213 installed in the same oil drain channel 211 are vertically offset. When hot oil flows along the oil drain channel 211, a large number of polyester fiber meltblown cloths can adsorb the metal impurities in the hot oil. The polyester fiber meltblown cloths are made of high temperature resistant modified materials, with long-term temperature resistance ≥150℃ (matching the normal working temperature of transmission oil 80-120℃, and able to cope with short-term peak 180℃), avoiding filter material shrinkage and pore deformation at high temperatures, thus ensuring the filtration effect of the corrugated filter plate 21.

[0031] Secondly, a rubber sealing frame 22 is provided at the top opening of the corrugated filter box 2. The rubber sealing frame 22 is tightly pressed against the top of several corrugated filter plates 21. After the annular pressure plate 3 is pressed against the top of the corrugated filter box 2, the rubber sealing frame 22 is tightly clamped between the annular pressure plate 3 and several corrugated filter plates 21. Under the sealing effect of the rubber sealing frame 22, hot oil can be prevented from seeping into the gap between the corrugated filter box 2 and the filter pipe 1, ensuring that hot oil can stably enter the interior of the corrugated filter box 2.

[0032] like Figure 1 and Figure 2 As shown, in order to improve the firmness of the corrugated filter box 2 after installation, several built-in support plates 12 are fixedly installed on the inner side wall of the filter tube 1. The top outer side wall of the corrugated filter box 2 is tightly clamped between the built-in support plates 12. Several fixing bolts 31 are passed through the annular pressure plate 3. The threaded end of the fixing bolt 31 passes through the annular pressure plate 3 and is threadedly connected to the matching built-in support plate 12 to ensure that the annular pressure plate 3 is firmly installed on the built-in support plate 12. At this time, the annular pressure plate 3 presses and positions the corrugated filter box 2 to ensure that the corrugated filter box 2 is firmly installed inside the filter tube 1.

[0033] Furthermore, to facilitate maintenance of the corrugated filter box 2, the annular pressure plate 3 can be disassembled by removing the fixing bolt 31, thereby releasing the pressure and positioning of the corrugated filter box 2 and allowing the corrugated filter box 2 to be removed from the filter tube 1, making it convenient to clean and maintain the metal impurities inside the corrugated filter plate 21.

[0034] Secondly, a first connector 4 is provided at the end of the filter pipe 1 away from the connecting pipe 5, and the first connector 4 is fixed to the oil outlet of the gearbox. A second connector 6 is provided at the end of the connecting pipe 5 away from the filter pipe 1, and the second connector 6 is fixed to the oil inlet of the cooler, ensuring that the hot oil in the gearbox can enter the cooler. Both the first connector 4 and the second connector 6 are fitted with an annular rubber ring 41, which seals the joint end of the cooling oil pipe and effectively prevents hot oil leakage.

[0035] In this embodiment, the first connector 4 is first fixedly installed on the oil outlet of the gearbox, and the second connector 6 is then fixedly installed on the oil inlet of the cooler. This ensures that the hot oil inside the gearbox can enter the cooler along the cooling oil pipe. After the hot oil enters the cooler and undergoes heat exchange, the cooled oil can be discharged back into the gearbox through the rubber hose fixedly installed between the cooler and the gearbox, thus cooling the gearbox. After the hot oil enters the cooling oil pipe, it first enters the corrugated filter box 2. As the hot oil flows along the drain channel 211, the large amount of polyester fiber meltblown cloth installed on the corrugated filter plate 21 can adsorb the metal impurities in the hot oil, reducing the probability of metal impurities entering the cooler along the connecting pipe 5. Discharging the hot oil through the drain channel 211 solves the problem that the overlapping and flat multi-layer filter structure easily obstructs the flow of hot oil. While ensuring the interception of impurities, it also ensures that the hot oil flows without obstruction, effectively improving the anti-clogging performance of the cooling oil pipe.

[0036] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
