Background
The leaf spring is the most widely used elastic element in the automotive suspension, and is an elastic beam with approximately equal strength formed by combining a plurality of alloy spring pieces with equal widths and unequal lengths (the thicknesses can be equal or unequal). When the leaf springs are mounted in the automotive suspension and the vertical load is positive, each leaf spring is forced to deform and tends to arch upward. At this time, the axle and the frame are brought close to each other. When the axle and frame are moved away from each other, the normal vertical load and deformation of the leaf spring is gradually reduced, sometimes even reversed. The flat rectangular steel plate is a bending type spring for a chassis formed by stacking a plurality of pieces, one end of the spring is arranged on the hanging bracket by pins, and the other end of the spring is connected to the girder by hanging lugs, so that the spring can stretch and retract. The method is currently suitable for some hard off-road vehicles without carrying the vehicle body and passenger/trucks. Its advantages are simple structure, high reliability, low cost and easy maintenance. It is both an elastic element of the suspension and a guiding device of the suspension. One end of the device is hinged with the frame, can transmit various forces and moments, and determines the jumping track of the wheels. Meanwhile, the self-friction damping device also has a certain friction damping effect. Three at one time, so that the suspension is widely used on non-independent suspensions.
