Single axle trailer leaf springs

 

Leaf spring is a spring composed of multiple pieces of elastic, uniform width and thickness, and different lengths of steel, and its shape is usually a long arc of rectangular section.
Function: The leaf spring is mainly used to connect the frame and axle of the trailer to play the role of suspension. It can withstand the impact of wheel load on the axle, reduce the violent vibration of the body, so as to maintain the driving stability of the trailer and the adaptability to different road conditions.

Single-piece German leaf springs are usually made of high-strength spring steel materials, which include the following common steel types:

 

1.60Si2MnA - A commonly used spring steel with high strength and good elasticity.
2.55CrMnA - Alloy steel containing chromium and manganese with good fatigue properties and wear resistance.
3.50CrVA - Vanadium-containing alloy steel with high strength and good fatigue resistance.

 

These materials undergo special heat treatments (such as quenching and tempering) to obtain the required mechanical properties such as high strength, high elasticity and fatigue resistance.

 

 

Single-piece German leaf springs are widely used in the following fields:

1.Automobile suspension system: The single-piece German leaf spring is an important part of the automobile suspension system. It is used to withstand and buffer the vibration between the body and the wheels, and improve the vehicle's ride comfort and handling performance.

2.Trucks and Heavy-Duty Vehicles: In trucks and heavy-duty vehicles, single-leaf German leaf springs are used to support the weight and cargo load of the vehicle, ensuring that the vehicle remains stable in various road conditions.

3.Railway vehicles: The suspension systems of railway vehicles often use single-piece German leaf springs to absorb and buffer unevenness and impact from the track, improving the smoothness and safety of train operation.

4.Industrial machinery: In some industrial machinery, single-piece German leaf springs are used to absorb mechanical vibrations and shocks, protect equipment and extend its service life.

5.Agricultural machinery: Agricultural machinery such as tractors and combine harvesters also use single-piece German leaf springs to improve the stability and work efficiency of the equipment.
