Typically when used in automobile suspension the leaf both supports an axle and locates/ partially locates the axle. 7.0. Get Quote. Oct 14, 2008 #3. A Belleville spring consists of a coned disk, as shown in the above figure. Leaf springs (also known as flat springs) are made out of flat plates. Variations in the spring deflection allow potential energy to be stored as strain energy and then released more gradually over time. GD&T Training Geometric Dimensioning Tolerancing Correlation of virtual values and experimental outputs are compared and reported. DFM DFA Training This means the suspension is smaller, flatter and lighter than a traditional setup. ii. E – Young’s modulus of the spring material. It should be noted that the ends of the leaves are not sharp and pointed, as shown below. Double Eye Truck Leaf Spring ₹ 55/Kg. ASTM A231. By design, leaf springs absorb vertical vibrations caused by irregularities in the road. For this reason, some manufacturers have used mono-leaf springs. One practice is that instead of keeping this large width one can make several slices and put the pieces together as a laminate. Elliot's invention revolutionized carriage design and construction, removing the need for a heavy perch and making transportation over rough roadways faster, easier, and less expensive.. Good corrosion resistance and electrical conductivity. Advertising Center Mono Leaf Spring – Consists of one main leaf where the material’s width and thickness are constant. This work investigates the feasibility of using a low cost and light weight material for automobile leaf springs. It takes driving torque and withstand the shocks provided by the vehicles. Therefore, once the design parameters, given on the left side of the above equation, are fixed the value of plate thickness, h can be calculated. Leaf springs are widely used in the automobile industry due to its high load bearing capacity and low manufacturing cost.
