Bow plate on the car, what is it?
The main spring force is serious, the weak force, to improve the main spring piece, often second pieces is also bent at the end of spring, the outside of the bag in the main piece of eye, called the package ear. In order to make the elastic deformation of each piece has the relative sliding between the main spring piece, and second pack ear leave a large gap. Some of the leaf spring suspension at both ends of the support is not made jaek, connection to other, such as rubber support pad.
Flat rectangular plate is curved, with several pieces of folded chassis with a spring, one end is arranged on the hanger to shoot, the other end use lug connected to the beam, the telescopic spring. Currently available for medium and large freight trucks.
When the leaf spring is installed in the suspension of the automobile, the vertical load is positive, and the spring pieces are subjected to force deformation and have the tendency of upward camber. At this point, the axle and the frame are close to each other. When the axle and the frame are far away from each other, the positive vertical load and deformation of the leaf spring gradually decrease, and sometimes even reverse.
An elastic element is widely used in automobile suspension spring, which is composed of a plurality of equal width but unequal (equal thickness, also can not equal) of elastic beam alloy spring sheet which is formed by the combination of an approximately equal strength.
