Normally-open built-in electric control shock absorber electromagnetic valve with novel iron core guide sleeve and magnetism isolating ring

Abstract

The normally-open built-in electric control shock absorber electromagnetic valve comprises an outer shell, an electromagnetic coil is arranged in the outer shell, the iron core guide sleeve is arranged in the middle of the electromagnetic coil, the magnetism isolating ring is arranged outside one end of the iron core guide sleeve, and the magnetism isolating ring is arranged outside the other end of the iron core guide sleeve. A sealing ring is arranged between the magnetism isolating ring and the inner side wall of the outer shell, and an iron core is movably arranged in the iron core guide sleeve, and is characterized in that the inner side wall of the magnetism isolating ring corresponds to the outer side wall of one end corresponding to the iron core guide sleeve, so that the magnetism isolating ring is tightly attached to the iron core guide sleeve; and the magnetism isolating ring and the iron core guide sleeve are connected together through welding. The electromagnetic valve is simple in structure and reasonable in design, the sealing performance of the electromagnetic valve is further improved, the electromagnetic valve is more convenient to produce and assemble, and the working stability of the electromagnetic valve is better.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a normally open built-in electronically controlled shock absorber solenoid valve with a novel iron core guide sleeve and a magnetic isolation ring. Background technique [0002] The shock absorber is mainly installed on the motor vehicle to realize the mechanism of the shock absorption function. At present, there is a type of shock absorber on the market that can adjust the damping force through a solenoid valve, which can effectively improve the flexibility of the shock absorber. The solenoid valve assembly is an important part of it, mainly including the outer casing, the solenoid coil, the iron core guide sleeve, the magnetic isolation ring and the iron core, etc. The magnetic isolation ring is arranged at the end of one end of the iron core guide sleeve A sealing ring is set between the iron core guide sleeve and the magnetic isolation ring to achieve sealing. The defect of this structure...

AI Technical Summary

Problems solved by technology

Among them, the solenoid valve assembly is an important part of it, mainly including the outer shell, electromagnetic coil, iron core guide sleeve, magnetic isolation ring and iron core, etc., wherein the magnetic isolation ring is set at the end position of one end of the iron core guide sleeve. A sealing ring is set between the iron core guide sleeve and the magnetic isolation ring to achieve sealing. The defect of this structure is that the sealing ring is prone to damage during long-term use, and then leakage occurs, which affects the operation of the solenoid valve. Normal use; In addition, the volume of the solenoid valve assembly is small, and the assembly operation of the iron core guide sleeve and the magnetic isolation ring is troublesome, and it is easy to have less installation, wrong installation and missing installation, and the magnetic isolation ring is generally made of brass material. The effect of its magnetic isolation is very limited, resulting in unstable electromagnetic characteristics
