Steel plate spring is made of steel plate spring, it is also known as leaf spring. In order to make full use of the material, the leaf spring is made in a form close to the stress beam. It has two types, one is equal to the thickness, the width of both ends narrow, the middle width. The traditional multi-piece steel leaf spring is this type, this kind of leaf spring is composed of multiple pieces of length, width of the same steel piece, now the bus, the majority of the use of this leaf spring.Steel Plate
The other is equal width, the thickness of both ends of the thin, the middle thick. Now the common small piece of leaf spring is this type, a small number of leaf spring is only 1 to 4 pieces of variable cross-section steel leaf spring, variable cross-section steel spring is the direction along the length of the steel plate to the center of the thicker to the two sides gradually thinning, or Sheet width and thickness of the plate are gradually changing the spring. Used for light cars, and now some large and medium-sized passenger cars tend to use this type of leaf spring.Steel Plate
The steel sheet of the multi-piece steel leaf spring is superimposed on the inverted triangle shape, the longest steel plate is the longest and the lowermost steel plate is the shortest, the sheet number of the steel plate is related to the weight and the shock absorbing effect of the supporting vehicle, The greater the rigidity of the spring. However, when the leaf spring is deflected, the pieces are slid against each other to produce noise. Friction can cause spring deformation, resulting in running uneven. Therefore, in the load is not a big car, there have been a small number of leaf spring to eliminate the defects of multiple pieces of spring.Steel Plate
The middle of the leaf spring is fixed to the axle by means of a U-bolt (also known as a horse-riding bolt), and the ends of the leaf spring are hinged to the bracket of the frame. In this way, through the steel plate spring will be connected with the car body, play a buffer, vibration, force of the role. Sheet spring as one of the important parts of the vehicle safety, both responsible for the transmission of all the forces and torque, but also has the elastic components, shock absorbers and guide mechanism characteristics, is an important high-load safety components. In recent years, domestic and foreign scholars on the design of steel leaf spring were studied.Steel Plate
