Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 1 and figure 2 , the hydraulic medium filter device includes a housing 1 and an annular filter medium assembly 2 .

[0039] The housing 1 is provided with an annular filter medium assembly installation cavity 5, and the annular filter medium assembly 2 is fixed in the annular filter medium assembly installation cavity 5 by thermosetting glue, and the inner cavity of the housing 1 is divided into an inner ring cavity 103 and the outer ring cavity 104 . In order to prevent the annular filter medium assembly 2 from moving in the annular filter medium assembly installation cavity 5 and act as a reinforcing rib, the height of the annular filter medium assembly installation cavity 5 is higher than that of the outer ring cavity 104 .

[0040] The casing 1 includes an upper casing 101 and a lower casing 102 , the edge of the ...

Abstract

The invention relates to a filter device, in particular to a hydraulic medium filter device used for an automatic transmission. The technical problems that a hydraulic medium filter device in an existing automatic transmission is short in service life, large in occupied space, complex in mounting procedure, and poor in filter medium use rate are solved. The hydraulic medium filter device used forthe automatic transmission comprises a shell and an annular filter medium assembly; an annular filter medium assembly mounting cavity is arranged in the shell, the annular filter medium assembly is located in the annular filter medium assembly mounting cavity and divides an inner cavity of the shell into an inner ring cavity and an outer ring cavity, the shell comprises an upper shell and a lowershell buckled with the upper shell, the top of the upper shell is provided with a medium outlet communicating with the outer ring cavity, the bottom of the lower shell is provided with a medium inletcommunicating with the inner ring cavity, the medium inlet is similar to the inner ring cavity in shape, and the annular filter medium assembly comprises at least two stages of annular filter media which are similar in shape and different in filter precision.

Description

technical field [0001] The invention relates to a filter device, in particular to a hydraulic medium filter device for an automatic transmission. Background technique [0002] During the working process of the automatic transmission, a large number of micron-sized particles will be produced due to the wear of the clutch, gear, bearing, bushing and hydraulic valve body. A large number of particles will reduce the cleanliness of the transmission oil, thus affecting the transmission. Key components, such as hydraulic control system actuators that are sensitive to oil cleanliness, cause irreversible damage. Therefore, it is necessary to install a hydraulic medium filter device in the transmission to ensure the cleanliness of the filter medium. [0003] The existing hydraulic medium filter devices in automatic transmissions are mostly divided into the following two types: one is to directly use hydraulic medium filter devices with higher filtering precision; the other is to use ...
