Car springs is one of the most popular and long-known types of elastic elements in the freight rolling stock. Spring is designed for load transfer to the frame and chassis, which comes from the bumps and irregularities of the roadway.

Spring of trucks

In the truck spring group design elastic element plays a very important role, because the area of trucks work covered almost all traffic categories (highways, dirt roads, off-road conditions). Depending on the category of road conditions design engineer selects the appropriate type of stiffening of the springs, taking into account the load on the suspension and vehicle ground clearance height.

The spring assembly is assembled together sheets of tempered metal of different length and thickness. These plates are fastened by means of studs. A thin layer of graphite lubricant is applied to reduce the friction between the plates of springs. Spring suspension arrangement is varied only by the number of plates and stiffness parameters.
