Description

Technical Field

[0001] The utility model relates to the technical field of electronically controlled air suspensions, in particular to an electronically controlled air suspension height-adjustable control device. Background Art

[0002] The Chinese patent document with the existing announcement number CN114889383A discloses an electronically controlled air suspension height adjustable control device, which proposes that in actual application, the air suspension of a vehicle is often used in linkage, and a single wheel is controlled by a single air suspension, but the existing air suspension is often installed with a single air shock absorber. Since the damping range of a single air shock absorber is limited, it requires uninterrupted continuous operation in continuously bumpy road conditions, resulting in a short service life of the air shock absorber, and when the bumping range of the vehicle is greater than the damping range of the air shock absorber, it is easy to generate a large burden; the solution is that the air suspension mechanism in this solution is installed on the front and rear of the vehicle through a lower connecting mechanism and an upper connecting mechanism The air suspension mechanism is composed of a lower air shock absorber and an upper air shock absorber, so that the lower air shock absorber and the upper air shock absorber can adjust the height of the lower connecting mechanism and the upper connecting mechanism, so that the heights of the front and rear ends of the vehicle can be adjusted independently, so that when the vehicle passes through uneven road conditions, the vehicle can always maintain a level, thereby reducing the bumpy amplitude of the vehicle; the lower connecting plate, the supporting mechanism, and the upper connecting plate are connected, and when the continuous uneven amplitude of the road surface is greater than the damping amplitude of the lower air shock absorber and the upper air shock absorber, the spacing between the lower connecting plate and the upper connecting plate can be reduced or increased, thereby changing the horizontal height of the vehicle, and further reducing the shock absorption through the lower air shock absorber, the supporting mechanism and the upper air shock absorber, thereby improving the shock absorption effect and reducing the bumpy amplitude of the vehicle.

[0003] When the above scheme and the prior art are used for the height-adjustable control device of the electric-controlled air suspension, the height of the electric-controlled air suspension is regulated by driving the turntable to rotate through the servo gear, driving the adjusting rod to slide in the slide groove on the surface of the mounting table. The regulating method will cause the electric-controlled air suspension to shake left and right due to the adjustment rod sliding left and right in the slide groove, which cannot meet the actual use requirements.
