It is then mounted to the axle of the vehicle using large U-bolts, securing the suspension in place. The elasticity of the spring steel allows for a pliancy within the suspension for comfort and control of a car while moving, and a leaf spring setup has been proven as a viable option for cars for many decades, despite only really being found on HGVs and Military vehicles these days.
They can take huge vertical loads being applied to them due to their tight-knit structure, hence why heavy duty industries still use them. Vertical loading is also distributed throughout the length of the leaf spring rather than acutely through a small spring and damper, which can potentially create a concentrated force too large for the suspension to handle. In a car, damping can be an extremely important characteristic. If the suspension is under-damped, the car will wallow and bounce around well after hitting any bump or pot hole in the road.
This was a significant characteristic in cars that used helical springs before the dawn of the shock absorber and was disadvantageous to cars when driven at any real pace. Leaf springs coped much better with vehicle damping due to the friction between each plate of steel which made the response time after a vertical flex in the suspension much quicker, thus making for a much more controllable car.
Leaf springs were simple in design and cheap to produce in comparison with the early springs and dampers therefore it was the go-to setup once cars were being fully mass produced to ensure reliability while keeping costs low. Monoleaf springs were the simplest design of the lot, using only one leaf of spring steel which tapered from thick in the middle to thin at the edges known as parabolic leaf springs to distribute the vertical loads appropriately. A single leaf setup could only however be used on extremely lightweight vehicles due to the lack of strength within the bar.
In racing and performance car applications, it is vital to be able to manipulate a suspension setup for the driving conditions and for different driving styles, something that is much easier nowadays through adjustable coilovers. This lack of adjustability of leaf setups is emphasised by the fact that the ends of the leaf springs are attached to the chassis, which leaves very little scope for shortening or lengthening of the leafs.
Adjustments can therefore only really be made through the strength and flexibility of the material used to make up the leaf springs. Leafs also allow very few directions of motion and are only really designed to move vertically, while a spring and damper combination can be manipulated into a much larger range of motion. Without leaf springs, construction vehicles would not be able to tote heavy loads. Leaf springs allow construction vehicles to carry heavy items like brick, stone, concrete and other massive materials.
A vehicle's size is largely unimportant. Unless it's designed to support overbearing loads , it will not carry out its duty, resulting in breakdowns and unnecessary costs. In addition to transporting construction items, leaf springs are also beneficial for operating machinery in areas that tend to receive high amounts of snow.
High volumes of snow can get heavy once they freeze. Equipping your truck with heavy-duty leaf springs will alleviate any unnecessary stress, making it last through the winter. Trucks need leaf springs for hauling trailers and other equipment. Leaf springs keep the load stable and the cargo grounded.
Without them, the trailer would sway and bounce, lifting off the pavement after minor bumps. This issue is why leaf springs are so critical for trucking — they promote safety on the road and protect cargo from damage.
If a truck is carrying fragile or dangerous goods, these vehicle elements become especially important.
