Automobile springs are suspension elastic components widely used in traditional automobiles. Its advantages are simple structure, reliable work, low cost and convenient maintenance. It is not only the elastic element of the suspension, but also the guiding device of the suspension. One end of it is hinged with the frame, which can transmit various forces and moments and determine the wheel's bounce trajectory. At the same time, it also has a certain friction and shock absorption effect. Kill three birds with one stone, so it is widely used in non-independent suspensions.
Its disadvantages are that it can only be used for non-independent suspensions, with heavier weight, high rigidity, poor comfort, long longitudinal dimensions, which is not conducive to shortening the front and rear suspensions of the car, and the leaf spring pins connected to 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 leaf springs, reduce weight, and increase service life, variable-section leaf springs, single-leaf springs, etc. have appeared.
