Multi-leaf spring

48110-60250 Multi-leaf Spring

Automotive leaf springs are also called blade springs.

The main function of automotive leaf springs is to act as an elastic element of the automotive suspension system. In addition, the friction between multiple springs acts as a damping function of the system. Most automotive leaf springs have a guiding function through rolling lugs and brackets. However, in terms of its basic stress and structural characteristics, automotive leaf springs have the following two basic characteristics:

1. No matter what form the automobile leaf spring is installed on the car, it works in the form of a beam, that is, its main force direction is perpendicular to the length of the leaf spring. At the same time, due to the small deformation relative to its length, the theory of small deflection beams in material mechanics, that is, the linear principle, can be used for analysis and calculation.

2. The bending moment of the automobile leaf spring on the car is basically a unidirectional load, so its bending stress is also a unidirectional stress.
