Delong F3000 car leaf spring leaf spring 2014 Chang-car manufacturers good

Chang Tong steel multi-piece leaf spring is unequal and unequal curvature laminated together. After installing both ends of the natural bent upward. When the road to face the impact of the wheels coming, plate deformation, cushion, damping effect, has the effect of Shihai arranged longitudinally oriented transmission power. Most non-independent suspension uses bow board to do the elastic element, eliminating the need guides and damper, simple structure. Chang Tong automotive leaf spring suspension system most widely used an elastic element, which is composed of several pieces of equal width but unequal length (thickness may be equal or may not equal) alloy spring sheet of an approximate combination and other elastic beam intensity. When the bow plate installed in the vehicle suspension, are exposed to a forward vertical load, the force of each spring piece are deformed, curved arch upward trend. In this case, axle and frame it close to each other. When the axle and the frame away from each other, bow plate forward suffered the vertical load and deformation will be gradually reduced, and sometimes even reversed. The main piece of the Word stress seriously, is weakness, in order to improve the forces the main piece of the Word, often also bent end of the second sheet of the Word, including outside the main piece of the Word, called the package ear. To make each piece of elastic deformation when there is the possibility of sliding between the main piece of the Word and the second sheet aural left a large void. Suspension ends some boards do not bow made of the Word, and the use of other support connections, such as the rubber support pads. Flat rectangular plate curved shape, with a few pieces of folded chassis springs, one end studs mounted on the hanger and the other end connected to the beam lug, the spring can stretch. Currently available in the medium and large cargo trucks.
