Project Report For Leaf Spring
Project report for Leaf Spring is as follows.
A straightforward type of spring frequently utilised for the suspension in wheeled vehicles is the leaf spring. One of the earliest types of vehicle suspension is the laminated or carriage spring, also known as a semi-elliptical spring, elliptical spring, or cart spring.
A leaf spring is made up of one or more thin, arc-shaped, narrow plates that are fastened to the axle and chassis so they can bend vertically in reaction to imperfections in the road surface. Although transverse leaf springs are also widely used, lateral leaf springs are more frequently used because they run the length of the vehicle and are mounted perpendicular to the wheel axle.
The suspension system of an automobile uses a leaf spring to smooth out bumps on uneven road surfaces while supporting the car. Such springs are made of leaves and may have one or many leaves. They are one of the more established suspension systems for wheels. In LCVs and HCVs, they are primarily utilised.
The centre hole punching, flat bar shearing, heating procedure, and heating treatment all come under the umbrella of the automotive leaf spring manufacturing process. One of the biggest trends in the automotive business is weight loss.
It can be accomplished primarily by introducing better materials, optimizing design, and using improved production techniques. The relative cost as well as the material’s strength are taken into consideration when choosing any material for a certain application.
Steel that has been hardened—either prior to or after spring formation—is frequently used to make springs. Long stock wire is used for helical springs, such as compression springs, and it is fed through an auto-coiler.
If a smaller run is being produced, the wire stock can also be wound on a lathe, but there are numerous safety issues to take into account. If spring wire is not secured or if a machinist loses control of it, it will dramatically uncoil. For individuals around, this uncoiling action can be exceedingly dangerous, especially if the wire is a heavy gauge.
A device that can twist spring wire into a coiled shape is called an auto-coiler. It is a separate machine even though it shares the same name as an auto coil gearbox for cars. They are frequently programmable devices that allow the coil tension, length, and number to be changed.
In auto-coilers, spring wire is quickly spun around a cylinder after being fed through headers by rollers. The spring is compelled to assume a coiled helical shape by the fast spinning action. The next length of wire is then coil by the auto-coiler when the spring is ejected.
The construction of leaf springs differs from that of helical springs. A flat bar is sheared into shape first, and then several bars are punched together. The finished bars are trimmed by a number of machines to eliminate superfluous metal and taper the ends. After that, the spring is heated to harden the steel while still receiving other treatments, including painting finishes, to conform the spring to established aesthetic standards.
Market Potential Of Leaf Spring
The Automotive Leaf Spring market is projected to grow at a CAGR of 16.10% from 2022 to 2027, from a market size of USD 5.05 billion in 2021 to USD 16 billion in 2027.
The technology, material, style, and design of leaf springs have seen a striking transformation in the automotive industry. There are innumerable leaf-spring suspension designs with various mounting locations, forms, and sizes available all around the world. The market for automotive leaf springs is anticipated to increase steadily over the next few years, reaching an estimated value of INR 423.53 Crores in 2024.
Several factors are boosting the demand for leaf springs, but the largest growth driver is the increase in LCV and HCV production. The tight government rules to fulfil the safety and comfort standards are predicted to raise demand and sales of automotive leaf springs throughout the forecast period, both in terms of value and volume.
The demand for automobile leaf springs is anticipated to expand in the global market as LCV demand and long-term vehicle comfort needs both increase.The demand for automobile leaf springs from OEMs and aftermarket suppliers also rises as per capita disposable income rises and concerns about vehicle comfort and servicing become more widespread.
Due to the rapidly expanding global e-commerce industry, which will also raise demand for automobile leaf springs, it is projected that the demand for light commercial vehicles for order fulfilment would rise.
