Cummins®

The Cummins 3035821 Compression Spring is a specialized component designed for use in commercial trucks. Manufactured by Cummins Inc., a leader in the diesel engine market, this compression spring serves a specific function within the truck’s mechanical systems. To understand its role, it is helpful to first explore the basic concept of compression springs and their applications in automotive components. Compression springs are mechanical devices that resist compression, storing and releasing energy as they are compressed and then allowed to expand. They are widely used in various mechanical systems for their ability to absorb shock, maintain pressure, and return to their original shape after deformation ¹.

Basic Concepts of Compression Springs

Compression springs are helical springs designed to offer resistance when compressed. They function by storing potential energy when compressed and releasing it when the force is removed, allowing the spring to return to its original length. This principle is fundamental in many mechanical applications, where springs are used to absorb shocks, maintain pressure, or store energy. The materials commonly used in the construction of compression springs include steel alloys, which offer the necessary strength and durability for demanding applications ².
