Description

TECHNICAL FIELD

[0001] The utility model relates to gearbox solenoid valve technical field, specifically a kind of integrated gearbox solenoid valve filter. BACKGROUND

[0002] The existing gearbox solenoid valve needs to rely on the flow of hydraulic oil to control gear shifting actuator during working process. However, impurities such as metal particles, wear debris and other tiny contaminants may be mixed in oil during gearbox operation. If these impurities directly enter the solenoid valve, it may cause valve core to be stuck, hydraulic control to fail, and thus affect gear shifting smoothness and reduce the service life of gearbox. Therefore, in order to ensure normal operation of the solenoid valve, a filter device is usually added in the oil circuit system of the gearbox to reduce the impact of impurities on the solenoid valve.

[0003] Currently, the common filtering scheme of gearbox solenoid valve mainly adopts independent metal mesh filter or external oil circuit filter element for primary filtration. Although these filtering devices can block larger particle impurities to some extent, they are still difficult to effectively intercept small particles, especially ferromagnetic impurities, due to limited filtering precision. In addition, the external filtering device is usually installed at the upstream position of the gearbox oil circuit, which causes oil to be filtered after passing through the oil pump and part of the oil passage, and cannot directly protect the oil inlet end of the solenoid valve, increasing the risk of contamination of the solenoid valve. At the same time, the filter screen structure in the prior art generally adopts a simple fixed installation method, which may cause problems such as blockage, poor sealing or difficulty in replacing filter element during long-term use, resulting in high maintenance cost and affecting long-term stable operation of the gearbox. SUMMARY

[0017] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0018] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0019] For example, Figures 1-2The utility model discloses an integrated gearbox solenoid valve filter which comprises a filter core 1, and a filter paper 2 is arranged in the filter core 1, an upper end cover 5 is connected to the end face of the filter core 1, an upper surface of the upper end cover 5 is provided with an oil inlet pipe 6, and one end of the oil inlet pipe 6 is provided with an oil inlet 8.

[0020] In an embodiment of the utility model, the upper end face of the filter core 1 and the lower end face of the upper end cover 5 can be fixedly connected in a welding mode, and the end face of the upper end cover 5 is provided with a welding structure matched with the end face of the filter core 1, so as to ensure the connection strength and sealing property between the two, and prevent oil leakage. The magnet 3 can be fixedly connected with the support rib 4 in a riveting mode, and the magnet 3 is stably attached to the support rib 4 through the riveting mode, so that the ferromagnetic impurities in the oil can be effectively adsorbed, the filtering effect is improved, and the risk of jam caused by the accumulation of ferromagnetic particles in the solenoid valve is reduced.

[0021] The solenoid valve filter in the utility model is installed in the solenoid valve of the gearbox, the oil inlet pipe 6 and the oil inlet 8 replace the original oil inlet port of the solenoid valve of the gearbox, so that the oil is filtered by the filter before entering the solenoid valve of the gearbox. When the oil enters the solenoid valve of the gearbox, it first flows into the inside of the filter core 1 through the sealing rib 7 and the oil inlet 8, and in the inside of the filter core 1, the oil needs to be filtered by the filter paper 2 arranged inside, the filter paper 2 can effectively intercept the fine impurity particles mixed therein, so as to ensure the purity of the oil entering the solenoid valve of the gearbox, thereby reducing the influence of impurities on the operation of the solenoid valve, and avoiding the abnormal operation of the valve core caused by the accumulation of impurities in the solenoid valve.

[0022] Through the above arrangement, the solenoid valve of the gearbox can continuously obtain clean oil supply during the working process, the filter core 1 and the filter paper 2 inside the filter core 1 jointly act to ensure efficient filtration, and the magnet 3 further enhances the adsorption capacity of ferromagnetic impurities, thereby effectively improving the reliability and durability of the solenoid valve of the gearbox. In addition, the filter structure is compact, can be integrally installed with the solenoid valve of the gearbox, not only optimizes the installation convenience, but also reduces the modification of the original structure of the gearbox, thereby improving the applicability and promotion value.

[0023] In the embodiment, the sealing rib 7 is arranged on the surface of the oil inlet pipe 6 close to the oil inlet 8. The sealing rib 7 is mainly arranged to enhance the sealing effect of the oil inlet pipe 6 and the solenoid valve of the gearbox, prevent oil leakage, and ensure that the oil can be completely filtered by the filter core 1. At the same time, the sealing rib 7 can also improve the installation stability of the filter, so that it is not easy to loosen during long-term use, and the sealing failure caused by vibration or pressure fluctuation is reduced, thereby improving the reliability of the system.

[0024] As Figure 3As shown, in an embodiment of the utility model, the outer side of support rib 4 and magnet 3 is provided with limiting assembly, and limiting assembly is used for assembling magnet 3 between support rib 4 and upper end cover 5.Limiting assembly includes hinge 9, and hinge 9 is installed on the end face of support rib 4, the outer side of hinge 9 is rotatably connected with limiting rod 11, the end face of support rib 4 is installed with torsion spring 10, and the lower surface of magnet 3 is provided with limiting groove 12.The end of torsion spring 10 away from support rib 4 is connected with the surface of limiting rod 11, and the shape of one end of limiting rod 11 is matched with the shape of limiting groove 12.

[0025] In the embodiment, the purpose of the design is to ensure the stable connection of magnet 3 and support rib 4, and make the assembly and disassembly of magnet 3 more convenient and efficient.Through the setting of limiting assembly, not only the production efficiency of the whole device is improved, but also when the upper end cover 5 and filter element 1 adopt detachable connection mode, magnet 3 can be conveniently replaced, meeting the needs of maintenance and long-term use.

[0026] When magnet 3 needs to be installed between support rib 4 and upper end cover 5, first, two limiting rods 11 can be manually rotated to rotate on the end face of support rib 4 around hinge 9, and at the same time, torsion spring 10 is stretched to make limiting rod 11 temporarily away from the installation position of magnet 3.Subsequently, magnet 3 is placed between two support ribs 4, so that the top surface thereof is attached to the lower surface of upper end cover 5.Subsequently, limiting rod 11 is loosened, and under the action of the elastic force of torsion spring 10, limiting rod 11 is automatically reset, and one end thereof is embedded in limiting groove 12 on the lower surface of magnet 3, thereby ensuring that magnet 3 is stably fixed between support rib 4 and upper end cover 5, and the assembly is completed.

[0027] When disassembly is needed, limiting rod 11 can be manually rotated to make it away from limiting groove 12, and at the same time, torsion spring 10 is compressed to make limiting rod 11 disengage from the lower surface of magnet 3.At this time, magnet 3 can be taken out from between support ribs 4.The disassembly process is simple and convenient, and no additional tools are needed, which is convenient for maintenance and replacement of magnet 3, thereby ensuring the long-term reliable operation of the device.

[0028] The advantage of this design is that through the rotatable structure of limiting assembly and the reset mechanism of torsion spring, the quick installation and disassembly of magnet 3 are realized, avoiding the problems of complex installation and inconvenient maintenance caused by traditional fixing methods such as screws or welding.Because limiting rod 11 can be automatically reset and clamped into limiting groove 12 under the action of torsion spring 10, no additional fastening operation is needed, which greatly improves the assembly efficiency.Meanwhile, the structure ensures that magnet 3 will not loosen when subjected to vibration or flow impact of oil, thereby maintaining long-term stable filtering effect.In addition, the design makes the replacement of magnet 3 more convenient, reduces the maintenance cost and time, improves the durability and applicability of the whole device, and makes it more widely applicable to different types of gearbox electromagnetic valve filter systems.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
