AI Technical Summary

Technical Problem

Traditional solenoid valves are prone to airflow impact noise and mechanical whistling under high-frequency operating conditions, and repeated rigid collisions cause rapid wear of the sealing surface. Existing two-stage stroke opening structures are complex, have many parts, and require complicated assembly processes, resulting in high costs.

Method used

The vehicle chassis support air suspension solenoid valve adopts a simplified structure. It uses a hollow sealing plug and a lifting spring to replace the traditional multi-stage complex parts, realize a two-stage stroke opening function, reduce airflow noise and mechanical wear, reduce the number of parts and simplify the assembly process.

Benefits of technology

It effectively reduces airflow noise and mechanical wear, simplifies assembly processes, reduces the number of parts, lowers assembly costs, and improves assembly efficiency and vehicle NVH performance.

Abstract

The invention discloses a vehicle chassis supporting air suspension electromagnetic valve and a vehicle, and relates to the technical field of air path valves. The electromagnetic valve comprises a valve body, a movable iron core, a sealing plug and a lifting spring, a valve cavity is formed in the valve body, and a first vent hole and a second vent hole are formed in the valve body; the movable iron core is movably arranged in the valve cavity; the sealing plug is arranged at one end of the movable iron core and is provided with a hollow part; the lifting spring is at least partially located in the valve cavity and connected to the side, away from the movable iron core, of the sealing plug. In the valve closing mode, the sealing plug closes the second vent hole, and the hollow part of the sealing plug is in a compressed state under the pushing of the lifting spring; and in the valve opening mode, the sealing plug opens the second vent hole, and the sealing plug is pushed by the lifting spring, so that the hollow part is in a compressed state. According to the electromagnetic valve, a simplified structure is adopted to achieve the two-stage stroke opening function, airflow noise and mechanical abrasion are effectively reduced, meanwhile, the number of parts is reduced, the assembly technology is simplified, and the assembly cost is reduced.
