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.
About Leaf Springs
● Leaf springs are the most cost efficient suspension solutions for commercial vehicles.
● Despite of the fact that the history of leaf springs started more than 100 years ago, we can find leaf springs in the latest modern commercial vehicles.
● Leaf springs on commercial vehicles are not standardised parts therefore each vehicle manufacturer develops own solutions and on one vehicle platform several different variants are used.
● The results of this is a huge number of article numbers on the market. From technical point of view, leaf springs have three main types.
● Air linkers (often said trailing arms, linker springs or beam springs) are used together with air suspension. They are also a special type of parabolic springs.
Possible Problems With Leaf Spring: Why Leaf Springs Might Break Sometimes?
There can be several reasons:
1、material problems (inclusions in spring steel, surface problem);
2、leaf spring production mistakes (wrong heat treatment, microcracks or grooves on surface);
3、service installation problems (U-bolt nuts are not tightened);
4、usage (spring surface damaged during usage, bad road conditions, overload of vehicle) and many more.
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.
