Applications

Leaf Springs For Bus:What You Need To know

Leaf springs are the core components of bus suspension systems, mainly used to buffer road impacts, support vehicle weight and maintain driving stability. They are made of multiple elastic steel plates stacked together, using the deformation of the steel plates to absorb vibrations while taking into account load-bearing requirements.

Features and advantages:

1.High load-bearing capacity: suitable for heavy vehicles such as buses, with strong load dispersion capacity;

2.Simple structure: easy maintenance and low cost;

3.Durability: steel has good fatigue resistance and long service life.

Maintenance points:

Check the steel plate regularly for breakage, rust or bushing wear to avoid elastic failure affecting driving safety. Although some modern buses use air springs, leaf springs are still widely used in urban and rural buses because of their economy and reliability.

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.
