Abstract

The present invention relates to a vehicle body height multi-control apparatus for an air suspension system, wherein an air spring is interposed between a vehicle body and a suspension arm to control the vehicle body height by the injection and discharge of compressed air. The vehicle body height control apparatus comprises: a mechanical leveling valve which rotates in the forward and reverse directions and the upward and downward directions, or in the left and right directions, so as to control the injection and discharge of the compressed air; a valve driver which drives the leveling valve in the direction of the injection and discharge of the compressed air; and a controller which controls the operation of the valve driver. Thus, an inexpensive vehicle body height multi-control apparatus for an air suspension system, which has a simple structure to enable a user to freely control the vehicle body height as needed, is provided.

Description

technical field [0001] The invention relates to a vehicle body height multiple adjustment device for an air suspension system, in particular to a vehicle body height multiple adjustment device for an air suspension system that can adjust the vehicle body height with a simple structure according to the needs of users, has high practicability and is low in price . Background technique [0002] It is generally used in the air suspension system of a vehicle. As shown in FIGS. The mechanical height adjustment valve 540 and the connecting rod 553 that discharge the compressed air inside the air spring 530 (not shown) to the outside according to the change of the lower weight of the vehicle body 510 and maintain the height of the vehicle body. [0003] Among them, the mechanical height adjustment valve 540 is composed of a valve body 541 that supplies compressed air supplied from the air tank to the air spring 530 or discharges it from the air spring 530, and a rotary handle 551 t...
