Abstract

The invention relates to a magnetic filter for an automatic transmission, comprising an upper shell (3), a lower shell (1), an oil inlet (5) and an oil outlet pipe correspondingly disposed in the shells, and a filter element (2) arranged at the joint position of the two shells. The magnetic filter is characterized in that a set of permanent magnets (6) is disposed on the lower shell. The beneficial effects of the magnetic filter for an automatic transmission are that with the permanent magnets playing a role in filter of fine iron powders, the service life of the automatic transmission is increased, and filtering performance of the filter is improved.

Description

technical field [0001] The present invention relates to a car filter, especially a magnetic filter for an automatic transmission. Background technique [0002] The filter for the automatic transmission of the car is an important part of the transmission hydraulic system. It passes through the automatic transmission and the external oil cooler. In order to remove the impurities entrained in the fluid, the filter medium of the existing filter adopts a filter mesh structure, which has no ability to filter small impurities, resulting in these fine impurities Mixed in the hydraulic fluid, the most harmful one is the fine iron powder produced by wear, which increases the frictional resistance, increases power consumption, easily causes the oil temperature to rise, the oil quality to change, and the lubrication condition to deteriorate. Poor oil flow affects the service life of the automatic transmission. Contents of the invention [0003] The purpose of the present invention i...
