Abstract
The utility model relates to a magnetic filter used for an automatic transmission. The magnetic filter used for the automatic transmission comprises an upper shell (3), a lower shell (1) and an oil inlet (5) and an oil outlet pipe (4), wherein the oil inlet (5) and the oil outlet pipe (4) are arranged on the lower shell (1) and correspond with each other; the joint of the two shells is provided with a filter element (2). The magnetic filter used for the automatic transmission is characterized in that the lower shell is provided with a set of permanent magnets (6). The magnetic filter used for the automatic transmission has the beneficial effects that a certain filtering action is performed on tiny iron powder by adopting permanent magnets, therefore, the service life of the automatic transmission is prolonged, and the filtering performance of the filter is improved.
Description
Technical field
The present invention relates to automobile filter, especially a kind of filter cleaner that is used for automatic transmission.
Background technique
The filter cleaner that is used for automatic gearbox is the important component part of transmission fluid pressing system, and it again gets into transmission oil drain pan from cooler through filter cleaner through automatic transmission and the continuous circuit hydraulic fluid of external oil cooler; Filter medium through in filter cleaner, being provided with filters, so that remove the impurity that is entrained in the fluid, existing filter cleaner filter medium adopts filter structure; This structure can only cause these fine impurity to be mixed in the hydraulic fluid to not having filter capacity than small impurities, and wherein the most harmful is the tiny iron powder that produces because of wearing and tearing; It increases surface friction drag, increases power consumption, is prone to cause oily temperature rise; Oil changes; Worsen lubrication state, the oil flow in the valve body oil pipe is not smooth, influences the working life of automatic transmission.
Summary of the invention
The object of the invention is exactly for the filter screen that overcomes existing filter cleaner can not filter the defective of less iron powder, and a kind of magnetic filter that is used for automatic transmission is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of magnetic filter that is used for automatic transmission, comprise upper shell and lower shell body with and go up corresponding filler opening and oil outlet tube, be provided with filter core in the two housings junction, it is characterized in that: lower shell body is provided with one group of permanent magnet.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
On lower shell body, be provided with corresponding groove, permanent magnet is arranged in the groove.
Described permanent magnet is rectangular-shaped.
Said permanent magnet is arranged on the positive side of lower shell body filler opening near oil outlet tube.
Beneficial effect of the present invention adopts permanent magnet that small iron powder is played certain filtration, has improved the working life of automatic transmission, has improved the strainability of filter cleaner.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings:
Fig. 1 is a plan view of the present invention;
Fig. 2 is an A-A sectional view of the present invention;
Fig. 3 is a rear view of the present invention.
1. lower shell bodys among the figure, 2. filter core, 3. upper shell, 4. oil outlet tube, 5. filler opening, 6. permanent magnet
Embodiment
As shown in Figure 1, a kind of magnetic filter that is used for automatic transmission of the present invention comprises that upper shell 3 is provided with oil outlet by the upper shell 3 of nonmetallic material molding and forming; Described oil outlet is positioned at upper shell one side, and protruding end oil duct formation oil outlet tube 4, and is as shown in Figure 2; Upper shell 3 compresses through the punching press flange with the lower shell body 1 of corresponding matching and realizes being connected; Be provided with filter core 2 in the junction of upper and lower two housings, filter core 2 compresses through the upper and lower casing flange and realizes fixing, and is as shown in Figure 3; On lower shell body 1, be provided with filler opening 5; Be provided with two rectangular recess at the lower shell body oil inlet hole near the positive side of oil outlet tube,, be provided with corresponding permanent magnet 6 in each rectangular recess.Beneficial effect of the present invention adopts permanent magnet that small iron powder is played certain filtration, has improved the working life of automatic transmission, has improved the strainability of filter cleaner.
