Abstract

The invention discloses an electro-hydraulic control inverse electromagnetic valve of an AT (automatic transmission). The electro-hydraulic control inverse electromagnetic valve comprises a valve body. The valve body is hollow-tubular shaped and is provided with openings in two ends, one end of the valve body is connected with a shell while the other end is connected with a rear cover, a valve spool penetrating the openings in the two ends of the valve body is arranged inside the valve body, one end of the valve spool is sleeved at one end of a spring, the other end of the spring is abutted against the rear cover, the spring can be extruded to deform through the valve spool, the other end of the valve spool extends into one end, abutted against a gag bit, of the shell, the gag bit and one end, extending into the shell, of the valve spool are jointly wrapped inside a yoke iron component, a coil wraps the yoke iron component and is arranged between gaps of the shell and the yoke iron component, and a membrane capable of sealing the joint is arranged at the joint of the valve body and the shell. The electro-hydraulic control inverse electromagnetic valve has the advantages that complete localization of the electro-hydraulic control inverse electromagnetic valve of the AT can be realized, the product technology is fully localized in material, structure and technology on the basis of the domestic technology development state, and mass production of the electro-hydraulic control inverse electromagnetic valve is facilitated.

Description

technical field [0001] The invention belongs to the technical field of hydraulic ATF control execution of AT automatic transmission, and relates to an electro-hydraulic control inverse proportional solenoid valve for AT automatic transmission. Background technique [0002] The automobile automatic transmission inverse proportional solenoid valve was first produced by Denso Corporation of Japan, and has been supplying my country's automobile industry with the technology of the complete set of automobile automatic transmission. The automatic transmission pressure control solenoid valve is one of the vulnerable components. The product technology It has become a bottleneck technology in my country's automobile manufacturing industry and the automobile aftermarket. There are some small companies in the Zhejiang area of ​​China who are trial-manufacturing, but due to technical reasons, the trial-manufacture has not been successful in China at present, and the technology of similar ...
