Suspension systems are systems of springs and shock absorbers on a vehicle that absorb impact and assist with handling. Suspension systems do much more than simply make your ride more comfortable and are vital to your vehicle driving correctly.
The term suspension refers to a system of shock absorbers, linkage, and springs that connect the wheels to a vehicle. Suspension systems have two purposes, to keep the occupants of the vehicle comfortable as they travel over bumps and obstacles on the roadway, and to enhance the handling capabilities.
The braking and handling of the vehicle is kept safely in check by the suspension systems by giving spring to the entire vehicle, allowing the driver to maneuver more efficiently. Likewise, the occupants of the vehicle are shielded from the jarring associated with vibrations, road noise, and bumps. The suspension systems also help to protect the vehicle and the cargo inside from wear and damage.
Suspension systems can be found on four wheel, two wheel, and even 18 wheel vehicles. In all instances, the purpose remains the same, although the overall size, materials, and make up may be different between them.
In order to create a properly functioning suspension system, mathematical computations must be calculated. Factors such as spring rate, wheel rate, roll couple percentage, weight transfer, unsprung weight transfer, travel, and damping must be considered. If even the slightest miscalculation should occur, a vehicle and its occupants could be gravely endangered.
Interestingly, it is not necessary for a vehicle to operate by wheel conveyance in order to be fitted with suspension systems. A classic example of this irregularity can be found in the military, where armored fighting vehicles are often equipped with suspension systems rigorous enough to travel over even the least maneuverable terrain. These tanks can weigh as much, or more than, seventy tons, yet they can travel with the slightest of ease thanks to the suspension systems underneath. The suspension systems of army vehicles are built much stronger than those for civilian use, considering the higher amount of use and the likelihood for damage in combat missions.
