This work investigates the feasibility of using a low cost and light weight material for automobile leaf springs. Leaf springs were very common on automobiles, right up to the 1970s in Europe and Japan and late 1970s in America when the move to front-wheel drive, and more sophisticated suspension designs saw automobile manufacturers use coil springs instead. GD&T Training Geometric Dimensioning Tolerancing It takes driving torque and withstand the shocks provided by the vehicles. The 2016 Volvo XC90 has a transverse leaf spring in high tech composite materials, a solution that is similar to the latest Chevrolet Corvette. From the stress and deflection equations the thickness of the spring plate, h, can be obtained as. I pulled out some leaf springs with lables on, along with the numbers, they said Made in the USA. It provides braking torque. However, the bolt holes required to engage the bolts to clamp the leaves weaken the spring to some extent. In this design, inter-leaf friction is unwanted, and therefore there is only contact between the springs at the ends and at the centre where the axle is connected. Structural steel Young’s Modulus,(E) 2*105 MPa Poisson’s Ratio. You can also observe from the picture of the leaf spring that the thickness of the whole spring is maximum at the centre and is gradually decreases towards the ends. 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. A leaf spring takes the form of a slender arc-shaped length of spring steel of rectangular cross-section. h = Height or thickness of leaf spring ii. Glass/Epoxy leaf spring. This means the suspension is smaller, flatter and lighter than a traditional setup. Engineering Forum Get Quote.

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. DESIGN AND ANALYSIS OF LEAF SPRING BY USING COMPOSITE MATERIAL FOR LIGHT VEHICLES Syambabu Nutalapati B. Get Quote. Boundary Limitations The spring is placed on vehicle's axle The complete vehicle load rests on the leaf spring. This design is characterized by fewer leaves whose thickness varies from centre to ends following a parabolic curve. Because the positioning of the axle is carried out by the leaf springs, it is disadvantageous to use soft springs springs with low spring constant. The inter-leaf friction between the leaf springs affects the riding comfort. Test Material-Only fully processed new springs which are representative of springs intended for the vehicle shall be used for the tests. Unlike coil springs, leaf springs also locate the rear axle, eliminating the need for trailing arms and a Panhard rod, thereby saving cost and weight in a simple live axle rear suspension. 18.5. b = Width of leaf spring Property . As an example of non-elliptic leaf springs, the Ford Model T had multiple leaf springs over its differential that were curved in the shape of a yoke. Beryllium Copper. // --> Mono Leaf Spring – Consists of one main leaf where the material’s width and thickness are constant. Plain carbon steel (SAE 1095) having 0.90 to 1.0% carbon is used to manufacture leaf springs. Double Eye Truck Leaf Spring ₹ 55/Kg. Prototypes of leaf springs are produced and their natural frequency measurements, stress levels under maximum load through strain gauges as well as life tests are completed. The spring leaf is made up of an arc-shape, slender piece of steel that is stacked with the same material in smaller sizes and bolted together creating a reinforced bow-like item. Composite leaf springs are not new to the automotive industry. The camber is provided so that even at the maximum load the deflected spring should not touch the machine member to which it is attached. How Do Leaf Springs Work? Chrome Vanadium.
