Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a filtering device for an automobile gearbox. Background Art

[0002] In order to give full play to the best performance of the engine, the automobile gearbox is needed to coordinate the engine speed and the actual driving speed of the wheels to give full play to the best performance of the engine. After the gearbox has been used for a long time, the friction between the metal components will produce fine chips and impurities will be mixed in the lubricating oil. If it is not processed, the service life of the gearbox will be reduced. In order to avoid this situation, a gearbox filter device is needed.

[0003] A Chinese patent discloses an automobile transmission oil filter that is easy to disassemble and assemble (publication number CN218686892U). This patented technology is provided with a sealing airbag, and the positioning plate squeezes the active airbag on the plug-in rod, so that the airflow inside the active airbag can enter the sealed airbag through the air pipe.

[0029] The following is combined with Figure 1-6 The utility model is described in further detail.

[0030] The embodiment of the utility model discloses an automobile transmission filter device.

[0031] Reference Figure 1 and Figure 2 A vehicle transmission filter device includes a housing 8, a sealing ring 32 is connected to the top of the housing 8, a cover plate 2 is connected to the top middle position of the cover plate 2, four positioning rods 3 are connected to the outer edge of the cover plate 2 in a circular manner, a pair of positioning blocks 12 are connected to the ends of the positioning rods 3, a positioning groove 21 is formed inside the positioning block 12, a first positioning mechanism is provided inside the positioning groove 21, and the first positioning mechanism is fixedly connected to the outer wall of the housing 8. An oil outlet pipe 9 is connected to the bottom of the housing 8;

The transmission oil enters the housing 8 through the oil inlet pipe 1, the oil outlet holes 24 and the filter element 22, and is then discharged through the oil outlet pipe 9, thereby completing the filtering of the transmission oil.

[0033] In some examples, the first positioning mechanism includes a positioning shell 4 annularly connected to the outer wall of the outer shell 8, and a first through hole 10 is opened on the top of the positioning shell 4. The end of the positioning rod 3 passes through the interior of the first through hole 10. The side walls of the positioning rod 3 are located below the positioning block 12 and are correspondingly connected to a pair of shafts 17. The outer side of the shaft 17 is rotatably connected to a buckle plate 13, and the top of the buckle plate 13 extends to the inside of the positioning groove 21. The end of the buckle plate 13 is slidably connected to a connecting rod 14. The outer side of the connecting rod 14 and located below the positioning shell 4 are slidably connected to a first fixed ring 6. The inner wall of the first fixed ring 6 is fixedly connected to the outer shell 8, and the end of the connecting rod 14 is connected to a movable ring 7. In a static state, under the elastic action of the first elastic member 5, the connecting rod 14 is lifted up, thereby driving the buckle plate 13 at the top of the connecting rod 14 to move toward each other, buckling the buckle plate 13 in the positioning groove 21, thereby completing the fixation of the positioning block 12.

[0034] In some examples, four pairs of second through holes 16 are annularly opened inside the first fixing ring 6, and the connecting rod 14 passes through the inside of the second through holes 16.
