Abstract

The invention relates to a cartridge proportional electromagnetic valve for clutch control, and belongs to the technical field of automatic transmission clutch control. The problems of a complex manufacturing process and high costs of a hydraulic part of an existing proportional electromagnetic valve are solved. The electromagnetic valve comprises an electromagnet assembly, a valve element assembly and a valve body assembly. When the electromagnetic valve is electrified and an electric ball valve is opened, oil liquid enters from an oil supply opening, a part of oil liquid flows out from an oil output opening to enter a working cavity to control oil pressure, and the other part of oil liquid flows back to an oil tank from an oil drainage opening. When the electromagnetic valve reaches a maximum operating current, a baffle closes the oil drainage opening, and only the oil supply opening and the oil output opening form a channel. The cartridge proportional electromagnetic valve is simplein structure and easy to process and assembly, reduces the oil liquid leakage of the valve body, and has high reliability.

Description

technical field [0001] The invention relates to the technical field of automatic transmission clutch control, in particular to a plug-in proportional solenoid valve for clutch control. Background technique [0002] With the continuous development of the automobile industry, the market share of vehicles equipped with automatic transmissions continues to increase. The clutch is an essential shift actuator in the hydromechanical automatic transmission, most of the clutches are controlled by the electro-hydraulic control circuit at present. As a pilot control element, the solenoid valve converts the electrical signal of the controller into a hydraulic signal and controls the response of the hydraulic circuit. It is a crucial control element in the clutch control circuit. In addition, in the hydromechanical automatic transmission, the locking of the torque converter is also realized by controlling the solenoid valve. Because the output oil pressure of the proportional solenoid ...
