Intelligent control proportional electromagnetic valve device

Abstract

The invention relates to an intelligent control proportional electromagnetic valve device. A circuit board is arranged in the electromagnetic valve device. The intelligent control proportional electromagnetic valve device comprises a coil, an armature, an ejector rod, a valve element, a housing, a base and a spring. The valve element comprises a hat-shaped housing and a multi-section type cylinderpiece. The ejector rod sequentially passes through a middle hole in the hat-shaped housing and an ejector rod groove of the armature and is in interference fit with the hat-shaped housing. The innerwall of the hat-shaped housing is embedded into a gap in the outer wall of the multi-section cylinder piece; the outer wall of the armature is arranged in a multi-section type cylinder piece inner wall of the multi-section type cylinder piece; the coil is wound on a coil framework which is sleeved outside the hat-shaped housing; the hat-shaped housing, the multi-section cylinder piece and the coilframework are all arranged in the housing; and the lower end of the spring and the armature sleeve the ejector rod. According to the intelligent control proportional electromagnetic valve device, theelectromagnetic valve device has a coil framework supporting structure and an armature movement guide structure which are easy to manufacture, and reliable and durable; and the bevel angle of the armature interacts with the flat-bottom wedge-shaped wall surface of the valve element to optimize the magnetic field of the coil, and thus the electromagnetic force levelness is improved.

Description

technical field [0001] The invention belongs to the field of motor vehicles, in particular to an intelligent control proportional solenoid valve device. Background technique [0002] In an environment where the number of cars is increasing, car companies are facing increasingly stringent fuel consumption and emission regulations. As an important part of dual-clutch transmissions, intelligent proportional solenoid valves play a role in precise control of vehicle gearbox shifting mechanisms. It can effectively improve the mechanical efficiency of the whole vehicle and reduce the fuel consumption rate, and greatly improve the emission, economy and handling; [0003] A proportional solenoid valve structure is disclosed in the existing patent (CN106795850A), wherein the armature is configured as a submerged armature and is connected with a push rod, and the push rod is mechanically coupled with the valve piston to finally push the valve piston to move axially, and according to T...

[0003] A proportional solenoid valve structure is disclosed in the existing patent (CN106795850A), wherein the armature is configured as a submerged armature and is connected with a push rod, and the push rod is mechanically coupled with the valve piston to finally push the valve piston to move axially, and according to The axial position of the pre-determines the limited flow through the valve, wherein the coil body has an inner peripheral surface, the armature is supported by the inner peripheral surface, no supporting body in the form of a supporting sleeve is required, but the electromagnetic valve described in this application The structural structure has high processing technology and high material performance requirements, and the coil body is more likely to fail and deform under temperature shock, and there are defects in reliability and service life

[0004] The patent (US20040056227A1) discloses a proportional pressure regulating valve, which includes an armature, an armature rod, a coil, a spool, a casing, a spring, etc., wherein the proportional solenoid valve has at least two spools, forming two gaps with the surrounding for The electromagnetic force is adjusted, and the two gaps can be adjusted independently. The size of the gap 1 is adjusted by the coil current, and the gap 2 is adjusted by the pressure proportional to the load demand of the hydraulic circuit; but the proportional pressure regulating valve mentioned in the application has two-stage spools, Depending on electromagnetic force and hydraulic pressure regulation, the control is difficult and the response is slow; more mechanical structures increase the difficulty of assembly

[0005] In addition, neither of the two solutions is implanted with a smart chip, and an algorithm needs to be provided externally, which increases the complexity of the vehicle's ECU
