1. Decompression formula transmission oil filter, including casing, cap, be equipped with the filter screen between this casing and cap, its characterized in that: the shell is provided with a coarse filter screen at the oil inlet of the shell, and the shell is provided with a magnet at the side edge of the oil inlet of the shell.

2. The reduced pressure transmission oil filter of claim 1 wherein: the magnet is fixedly clamped on the shell.

3. The reduced pressure transmission oil filter of claim 1 or 2 wherein: and a sealing ring is arranged on the shell cover and at the oil outlet of the shell cover.

Technical Field

The invention relates to a filtering system, in particular to a gearbox oil filter.

Background

At present, the oil filter that vehicle transmission used can not carry out better effective filtration to the iron-containing impurity in the transmission machine oil for this machine oil can constantly increase the filter pressure of filter screen in the loop filter process, thereby has influenced this oil filter's filtration efficiency and life.

The invention aims to overcome the defects of the technology and provide a decompression type gearbox oil filter capable of effectively filtering iron impurities in the gearbox oil.

The purpose of the invention is realized by the following technical scheme: a pressure reduction type gearbox oil filter comprises a shell and a shell cover, wherein a filter screen is arranged between the shell and the shell cover, a coarse filter screen is arranged on the shell and at an oil inlet of the shell, and a magnet is arranged on the shell and at the side edge of the oil inlet of the shell.

The magnet is fixedly clamped on the shell so as to be convenient to disassemble, assemble and clean.

After the structure is adopted, the magnet is additionally arranged at the side edge of the oil inlet of the shell, so that engine oil of the gearbox flows through the coarse filter screen and the side edge of the magnet when being circularly filtered, the engine oil is coarsely filtered, iron impurities in the engine oil are adsorbed by the magnet, and then the engine oil is finely filtered through the filter screen. This filtration and adsorption process is simple, and simple to operate has effectively alleviateed the filter pressure of filter screen part, makes the filter efficiency and the life of case speed changing machine oil cleaner obtain promoting, makes whole oil cleaner have the best filter effect to guarantee the normal operating of gearbox system.

The invention is described in further detail below with reference to the figures and embodiments.

FIG. 1 is a schematic diagram of a reduced pressure transmission oil filter according to the present invention.

Fig. 2 is a left side view of fig. 1.

Fig. 3 is a sectional view a-a of fig. 2.

Detailed Description

Referring to fig. 1 to 3, the decompression type transmission oil filter applied to an automobile of the present invention includes a housing 1 and a housing cover 3, a filter screen 2 (fine filter and fine filter) is installed between the housing 1 and the housing cover 3, a coarse filter screen 6 (coarse filter) is installed on the housing 1 and at an oil inlet 7 of the housing, and magnets 5 (a plurality of pieces distributed around the side) are installed on the housing 1 and at the side of the oil inlet of the housing.

An oil inlet 7 is arranged on the shell 1, an oil outlet 8 is arranged on the shell cover 3, and a sealing ring 4 is arranged on the shell cover 3 and at the oil outlet 8 of the shell cover and used for processing the sealing performance of the oil filter and the gearbox assembly. Magnet 5 passes through fixation clamp 9 dress on casing 1 to convenient dismantlement and the timely iron nature impurity of clearing up on the magnet.

When the engine oil in the gearbox flows circularly and is filtered, an oil inlet 7 of the shell 1 firstly flows through the coarse filter screen 6 and the side edge of the magnet 5 to perform coarse filtration on the engine oil in the gearbox, iron impurities in the engine oil are adsorbed by the magnet, and then the engine oil is subjected to fine filtration through the filter screen 2 and flows out of an oil outlet 8 of the shell cover 3.
