Spring steel plate classification

1、Multiple spring: composed of multiple pieces of steel with different lengths and the same width. The plates of multiple leaf springs are superimposed into inverted trianglesShape, the top of the steel plate is the longest, the bottom of the steel plate is the shortest, the number of steel plates and support the weight of the passenger car, the more the thicker the shorter the steel plate, the greater the spring rigidity.

2、 less spring: by the two ends of the thin middle thick, equal width and length of the steel sheet superposition. The steel plate section of fewer leaf springs changes greatly, and the section from the middle to both ends is gradually different, so the rolling process is more complex, and the price is more expensive than the spring. Compared with multiple spring, under the condition of the same stiffness (that is, the same bearing capacity), fewer spring is about 50% lighter than multiple spring, which reduces fuel consumption and increases ride comfort. And there is less point contact between the single spring, which reduces the relative friction and vibration, and increases the ride comfort

Spring steel plate application

Spring steel plate is a widely used suspension elastic element in traditional automobile. Its advantages are simple structure, reliable work, low cost, convenient maintenance. It is not only the elastic element of suspension, but also the guide device of suspension. It is hinged at one end to the frame to transmit various forces and moments and determine the trajectory of the wheel's bounce. At the same time, it also has a certain friction damping effect. It kills three birds with one stone, so it is widely used in non-independent suspension.
