AIR CHARGING AND DISCHARGING CONTROL DEVICE FOR AIR SPRING SUPPORT SYSTEM

摘要

Disclosed is an air charging and discharging control device for an air spring support system, the control device comprising a site control box (1) and an indoor control box (2). An air charging electromagnetic valve (3) and an air discharging electromagnetic valve (4) are mounted in the site control box (1). A PLC controller is mounted in the indoor control box (2), and the PLC controller is electrically connected with the air charging electromagnetic valve (3) and the air discharging electromagnetic valve (4) respectively, and is electrically connected with a pressure transmitter (5) which is arranged on an additional air chamber (9) of the air spring support system. By controlling the actions of the air charging electromagnetic valve (3) and the air discharging electromagnetic valve (4) with the PLC controller, air is charged into and discharged from the air spring support system so that the air spring support system has different inflation pressures, and static support for different vehicle weights is realized.
