Description

Technical Field

[0001] This invention relates to the field of automotive air suspension technology, and more particularly to a front axle lifting device for air-suspended vehicles. Background Technology

[0002] Air suspension systems are widely used in heavy vehicles due to their excellent shock absorption performance. Among them, the front axle lifting device of air suspension vehicles relies on lifting airbags to raise and lower the front axle to adapt to different driving conditions.

[0003] In existing air suspension vehicles, the lift airbags of the front axle lift system are mostly installed directly exposed at the bottom of the frame. During vehicle operation, road debris and other objects can easily impact the lift airbags, causing them to rupture and leak, significantly shortening their lifespan and affecting the stable operation of the lift system.

[0004] Meanwhile, the lack of protective structure on the outside of the airbag, coupled with long-term exposure to complex working conditions, makes it easy for a large amount of dust and sand to adhere to its surface. This not only makes it difficult to clean but also affects the normal expansion and contraction of the airbag, further reducing the reliability of the device.

[0005] Currently, there is no air suspension front axle lifting device that can simultaneously improve airbag protection and surface cleaning, making it difficult to meet actual usage needs.

[0006] Therefore, it is necessary to provide a front axle lifting device for air-suspension vehicles to solve the above-mentioned technical problems. Summary of the Invention
