Semi trailer air suspension-manufacture,factory,supplier from China

Products DescriptionDARO air suspension for semi-trailer can automatically adjust the height of the trailer according to the vehicle's load, maintain the stability of the vehicle, and improve the carrying capacity.

Products DescriptionSemi trailer air suspension：(1) High driving safety:When the vehicle passes the concave and convex road, overtaking or steers sharply, the stretch or compression travel of the air spring is relatively large, and the stiffness increases rapidly to adjust the balance of the vehicle, so as to reduce the vibration and roll angle, improve the safety of the vehicle, and ensure the integrity of the transported goods.(2) Good driving comfort: Due to the small internal friction between rubber and air during operation, it can absorb high-frequency vibrations and generate less noise,

Products DescriptionSolid welding-- automated fuel safety welding is adopted for ring seam/straight seam, Air tank for air suspension and each ends of the head are introduced with diameter discount process, so the welding is association and beautiful.Thickening cure--cylinder support, welding, interface are different thickening treatment, to make certain strength, no cracking, no air leakage.Design pressure of air reservoir:Above 7,000 paras (kpa)Material:1) Dimension: Ø280×840×2 2) Capacity: 40L 3) Wei

Products DescriptionIt can be raised or lowered. Can be lifted in two aspects, one is through the trailer air bag can be lifted, reduce wear, save fuel, especially suitable for one-way empty car situation. Second, through the manual height valve in the air suspension system, the height of the vehicle loading platform can be adjusted within a certain range, convenient loading and unloading of goods.The air spring is filled with air and has compressibility.

Products DescriptionDARO Group Trailer Air Suspension:Excellent shock-absorbing effect: The air suspension uses compressed air as an elastic medium, which has a better isolation effect than leaf springs. It can greatly absorb bumps and impacts from the road surface, improve driving comfort, and enhance the protection ability of goods.

Products DescriptionAir bag suspension trailer axle：(1) High driving safety: when the vehicle through the concave and convex road, overtaking or sharp steering, the stretch or compression stroke of the air spring is relatively large, the stiffness is rapidly increased to adjust the balance of the vehicle, so as to reduce the vibration and side Angle, improve the safety of vehicle driving, to ensure the good transport of goods.(2) Good driving comfort: because the rubber and air work less internal friction, can absorb high-frequency vibration, and produce less noise, and can absorb the body vib

Products DescriptionLess noise - with air as the medium, trailer air suspension much less friction, nearly zero noise at some point of use.Flexible lifting -- single axle or multi-axle lifting can be realized to alternate the peak of the physique and decrease tire loss; The car peak can be adjusted via the entire car lifting, adapting to distinct loading and unloading platforms, enhancing the loading and unloading efficiency.ModelInstallation Height （mm）Apply A

Products DescriptionDARO trailer air suspension:trailer air suspension has excellent shock absorption effect -- using compressible air as an elastic medium, trailer air suspension has a better shock isolation effect than a plate spring. It can substantially absorb bumps and shocks from the road. This can improve driving comfort and enhance the protection of goods, especially when transporting dangerous chemicals or fragile and high-value-added goods.

Products DescriptionAfter the DARO trailer air ride suspension is installed, the softness and length of the air spring can be adjusted by changing the hardness and length of the air spring, so as to obtain better comfort on uneven roads.
