There are many kinds of leaf springs, which can be classified according to the following classification methods:
1. Classified by raw material sizes
1) Small size leaf springs
It mainly refers to the leaf springs with material width range of 44.5 ~ 50mm and material thickness of 6 ~ 9mm.
There are mainly the following leaf springs:
Boat Trailer leaf springs, livestock Trailer leaf springs, RV leaf springs, station wagon leaf springs, utility trailer leaf springs, etc.
2) Light duty leaf springs
It mainly refers to the leaf spring with material width of 60 ~ 70mm and material thickness of 6 ~ 16mm.
There are mainly the following leaf springs:
Pickup leaf spring, van leaf spring, agricultural trailer leaf spring, minibus leaf spring, etc.
3) Heavy duty leaf springs
It mainly refers to the material width of 75 ~ 120mm and the material thickness of 12 ~ 56mm.
There are four main categories:
A. Semi trailer leaf springs, such as BPW / FUWA / YTE / TRAseries trailer leaf springs, with material sizes involving 75×13 / 76×14 / 90×11 / 90×13 / 90×16 / 100×12 / 100×14 / 100×16, etc.
B. Bogie(Single point suspension) leaf springs, involving 24t / 28T / 32t leaf springs for a boogie single point suspension, with material sizes of 90×13 / 16 / 18 and 120×14/16/18.
、
C. Bus leaf springs, involving Toyota / Ford / Fuso / Hino and other brands. Most products are parabolic leaf springs.
D. Heavy duty truck leaf springs, including Benz / Volvo / Scania / Hino / Isuzu and other models. The main products are parabolic leaf springs.
E. Agricultural leaf springs, which are mainly used on off-road transport trailers.
F. Air linkers(Trailing arm), mainly used for air suspensions.
2. Classified according to the section of flat bar
1) Conventional leaf springs: they are composed of multiple leaf springs with equal width and thickness and different lengths. The product manufacturing process is relatively simple and the manufacturing cost is low.
2) Parabolic leaf springs: they are composed of one or more leaf springs with thin ends, thick middle, equal width and unequal lengths. Compared with the conventional equal thickness leaf springs, they have many advantages: light weight; longer fatigue life; lower working noise; better ride comfortability and stability.
