How much for an airbag axle with air suspension?

Trailer suspension is a device installed between the frame and the trailer axle for force transmission connection, which can help the vehicle cope with complex road conditions and ensure the stability of driving.

Suspension can be divided into independent suspension and non-independent suspension two types, trailer suspension is based on non-independent suspension, both sides of the wheel mounted on the same axle, compared to the independent suspension structure is simpler, less expensive, and daily maintenance is easier.

Non-independent suspension can be divided into air spring type, oil and gas spring type, leaf spring type, at present in the domestic application is more leaf spring type and air spring type, that is, we often say steel plate suspension and air bag suspension. Among them, the popularity of steel plate Bridges is wider, accounting for more than 80%.

In recent years, air bag suspension gradually began to become the focus of the national standard promotion direction, according to the GB7258-2017 motor vehicle operation safety technical conditions of the national standard, three-axis fence plate semi-trailer, three-axis grid semi-trailer must be installed air suspension and disc brake, otherwise it will affect the vehicle license or road driving.

The difference between steel plate suspension and air bag suspension:

1. Steel plate suspension is mainly composed of leaf spring, suspension support, connecting rod, U-bolt, etc. The most obvious advantage is simple structure, low cost and maintenance cost, stronger rigidity, and higher carrying capacity. The disadvantage is that the weight is too large, which increases the weight of the vehicle, and the layout space is also large.

Generally speaking, steel plate suspension is more suitable for the transport of goods with large quality and low cargo damage requirements, such as wood, sand, coal, steel coil, the transport of these goods has higher bearing capacity requirements for vehicles, and is suitable for steel plate Bridges with stronger rigidity.

2, the air bag suspension is mainly composed of compressor, air reservoir, height control valve, air spring, control rod, etc., in addition to shock absorber, guide arm, transverse stabilizer rod and so on. Its advantages are light weight, can reduce the body weight, smoothness is better than the steel plate bridge, excellent shock absorption performance, and because the air medium friction in the air bag is small, there is almost no noise when working, the service life can reach 2-3 times of the leaf spring, and the shock absorption performance is better. The disadvantage is that the structure is complex, the cost of maintenance or replacement is high, the bearing capacity is worse than the steel plate bridge, and the aging and vulnerable speed is faster than the steel plate bridge.

In addition to the models that are required by regulations to use air bag suspension, air bag suspension is also suitable for the transportation of dangerous goods, flowers, green pass, precision instruments, etc., because of its good shock absorption effect, it can effectively control the cargo loss rate.

How much is the airbag suspension? The specific price also depends on the owner's choice of brand, model, configuration, etc. At present, most of the air suspension prices sold on the market are 12,000 yuan - 30,000 yuan, and the import configuration price is higher; 13t drum bridge price is more than 3000 yuan -5000 yuan, high-end line products can float to 6000 yuan or even 8000 yuan due to brand premium; The price of 13t disc brake bridge is about 5,000 yuan - 12,000 yuan.

For trailer accessories such as air bag suspension, the price is only a condition for purchase, do not be regarded as a decisive factor, although it is said that "one price one goods", but the saying also says "shop around", choose a cost-effective product is the most cost-effective.
