ABSTRACT
Nowadays Motor suspension is an important one assembly, which the frame and the flexibility to connect the axle. Its main role is to pass between the wheels and the body all the force and moment. The uneven road to ease the impact of body load and the attenuation is caused by vibration, to ensure passenger comfort, cargo and vehicles to reduce their load.
This article is about vehicles front and rear suspension design, flexible spring steel components for. Focus from the main parameters of front and rear suspension the determination and the calculation of elastic element. First of all, I have the form of the advantages and disadvantages of different suspension were compared, and then set the front and rear of vehicles the form of suspension for non-independent suspension leaf springs. And then focus on the design of suspension components. The first one is determination of the main parameters. The second one is the design and calculation of the elastic element and the calculation of the final selection of shock absorber.

Key words：suspension; elastic element; leaf springs
