The middle of the leaf spring is fixed on the axle through U-bolts (also known as riding bolts), and the roll ears at both ends are hinged to the brackets of the frame with pins. In this way, the axle and the body are connected by the leaf spring, which plays the role of buffering, damping and force transmission.
Features
The advantages are simple structure, reliable operation, low cost and convenient maintenance. It is both the elastic element of the suspension and the guiding device of the suspension. One end of it is hinged to the frame, which can transmit various forces and moments, and determine the wheel's beating trajectory. At the same time, it also has a certain friction damping effect. Kill three birds with one stone, so it is widely used in non-independent suspension.
Its disadvantage is that it can only be used for non-independent suspension, with heavy weight, high stiffness, poor comfort, long longitudinal dimension, which is not conducive to shortening the front and rear suspension of the car, and the leaf spring pins at the connection with the frame are easy to wear Wait.
Despite many shortcomings, leaf springs are still widely used in various automobiles. In order to improve the performance of the leaf spring, reduce the weight, and increase the lifespan, variable-section leaf springs, single-leaf springs, etc. have appeared.
