Novel suction type oil filter

Abstract

The invention discloses a novel suction type oil filter, which comprises a lower shell, a filter element and an upper shell; a mounting groove is formed in the center of the bottom of the lower shell;an oil inlet is formed in the bottom, close to the center of the right side, of the lower shell. A first flow dividing device is fixedly connected to the position, close to the oil inlet, in the lower shell. The top of the lower shell is fixedly connected with a lower connecting plate; the bottom of the upper shell is fixedly connected with an upper connecting plate; the upper connecting plate isfixedly inserted into the inner wall of the lower connecting plate, a filter element is fixedly connected between the upper connecting plate and the lower connecting plate, the upper connecting plateand the lower connecting plate are welded and fixed, an oil outlet pipe fixedly communicates with the center, close to the left side, of the top of the upper connecting plate, and a second flow dividing device is fixedly connected to the position, close to the oil outlet pipe, of the bottom of the upper connecting plate. In the invention, the inlet and outlet of oil are reasonably distributed, the phenomenon that residues are prone to being locally gathered at an oil outlet of an original filter bag type filter element is avoided, and meanwhile the use efficiency of the filter element is improved.

Description

technical field

[0001] The invention relates to the technical field of oil filters, in particular to a novel suction oil filter. Background technique

[0002] At the end of the 1930s, the application of hydraulic pressure and hydraulic transmission in automobiles gave birth to the emergence of automobile automatic transmissions in a real sense. After the 1970s and 1980s, with the development of electronic control technology, electro-hydraulic control transmissions have gained Rapid development, as an important transmission and control medium of electro-hydraulic controlled automatic transmission, automatic transmission fluid plays a vital role in automatic transmission, and the cleanliness of the oil has a great impact on many indicators of the transmission has an important impact. Among them, 50%-60% of the gearbox failures are directly or indirectly related to the pollution of the gearbox oil. In view of the above reasons, in order to reduce the impact of the gearbox oil ...
