Applications

The Air Linker is mainly applicable to the automobile air suspension.

● It is usually composed of one or two spring leaves, which are used symmetrically with left and right.
● It is installed between the axle and the air suspension bracket.
● It is formed as a whole, and its structure includes a straight part, a bending part and a eye rolling part.
● The rolled eye is equipped with a rubber composite bushing.
● The common material specifications of the guide arm are from 90 to 100 mm in width and from 20 to 50 mm in thickness.

The difference between the leaf spring and the air suspension:

● The suspension that supports the truck is a very important part that significantly affects the characteristics of the truck, so the type and condition of the suspension are important points to check when buying a used truck.
● Leaf spring is a type of suspension composed of spring plates with different lengths which is assembled near front/rear wheels of vehicles to be able to carry heavy objects.
● However, trucks which are produced lately is mainly installed a different type of spring called air suspension because it is uncomfortable to drive trucks with leaf spring.
● But leaf springs are still used on heavy commercial vehicles such as vans and trucks due to its durability.
● Leaf spring consists of multilayered spring plates. The longest spring called main spring is attached to chassis supported by shackles.
● Leaf spring makes it possible to absorb impact and vibration from a wheel by bending the spring plate. There are two types of name for the leaf spring.
● One of them is called ‘over slung’ when the leaf spring is putted on the upper side of the axle. The other one is called ‘under slung’ when the leaf spring is putted under the axle.
● The place to be putted the leaf spring depends on the vehicle type.

Advantages and disadvantages of leaf spring：

ADVANTAGES
● It can bear heavy loads
● Not expensive to repair comparatively
The material of leaf spring is made of steel so that means it is very strong and withstand heavy load. Also, it is cheaper to maintenance than the other suspension as the structure is simple.

DISADVANTAGES
● Not comfortable to ride
● It can be damaged easily
It is not comfortable to ride in, and it could jump you up when you hit a step because leaf spring is made of steel.
However, the cost to repair will be much cheaper than air suspension, so leaf springs are still used on heavy commercial vehicles such as vans and trucks.

Reference

Provide different types of leaf springs which include conventional multi leaf springs, parabolic leaf springs, air linkers and sprung drawbars.
In terms of vehicle types, it include heavy duty semi trailer leaf springs, truck leaf springs, light duty trailer leaf springs, buses and agricultural leaf springs.
