Introduction to the development history of automobile leaf spring

The suspension systems used in early vehicles were relatively primitive, but with the development of technology and the process of industrialization, the suspension systems of automobiles have gradually been upgraded, and leaf springs are one of them. This article will introduce the development history of automobile leaf springs.

Leaf spring originated in the carriage era

   The wife of Milton Rimond, one of the inventors of the electric car, once complained that the protruding cams on the carriage made her uncomfortable. Rimond studied the springs used in the manufacture of carriages, combined with the stability and reliability required by the carriages, so in 1828 he manufactured a more stable and powerful leaf spring suspension system for his carriages. The device originally consisted of a series of curved metal sheets that bounced back nicely when compressed. Soon after, his invention was widely used in other carriages.

   The Birth of Automobile Leaf Springs

   With the development of automobiles, people have gradually abandoned carriages and wooden frames, thus also abandoning the original spring suspension system, which also promoted the birth of automobile leaf spring suspension system. The leaf spring suspension system was made in 1901, and it was one of the widely used systems at that time.

   Application of leaf spring

   Leaf springs can withstand a lot of pressure, which is great for heavy cars and trucks. Due to the strength of the leaf springs, they can well support loads that are also much larger than themselves, and also correctly withstand several powerful vibrations acting on the same car at the same time. For decades, manufacturers have sought better solutions, such as shock absorbers, to make vehicles more stable and smooth.

   Modernization of Leaf Springs

   Over time, leaf springs have improved in terms of materials and manufacturing methods. Today's leaf springs are usually made of steel with high strength and elasticity. Modern manufacturing techniques use pressure and heat treatment methods to condition leaf spring properties, resulting in a stronger, more resilient product.

   in conclusion

   With the development of modern automobile technology and innovation, the application of leaf springs is not limited to trucks, they are being widely used in various types of automobiles, not only for off-road vehicles, trucks and other heavy-duty vehicles, but also for ordinary cars and Bicycles allow vehicles to have a more stable driving performance. In addition, leaf springs are used in other mechanical and industrial applications, and their application value will continue to expand.
