Controlling the car is the main objective of the vehicles suspension. An automotive suspension is a setup of many various parts in which the body of the car sits on. The suspension provides steering control, handling and most of the time comfort for the driver and passengers. If the world was perfect, all surfaces would be flat and suspension on vehicles would not be needed. The car's suspension helps with any irregularities on the driving surface.
With so much time spent driving and sitting in a car, a comfortable ride is a must. There is nothing worse than going over bumps shaking the entire car. The car wouldn't be drivable without suspension components for the body to rest on. An automotive suspension allows the car to sit above the surface and hover over the road while maintaining ride quality and handling. Every vehicle manufacturer creates their suspension using different ideas and different designs. On nearly every vehicle made today, a driver will notice a suspension change in each one.
Basic components of a typical car suspension include the frame, steering system, tires and wheels, and the suspension system. The frame is a very large structural piece that supports the car's body and engine. The frame is then supported by the car's suspension system. This system also absorbs any shock that may occur while driving. The steering system is a complex system that allows the driver to direct the vehicle to where it needs to go. Tires and wheels allow the car to move and provide grip on the surface. With each one of these separate suspension components, their main goal is achieved when all are properly maintained and serviced.
The springs, anti-sway bars, and dampers are the three major parts in the vehicles suspension system. These components work together to allow the vehicle to handle and drive at its best capability.
Car springs are vital to absorb any irregular surface the vehicle may drive over. The spring compresses and absorbs the shock. Many vehicles, especially cars, use a coil spring. This is the most common type of spring. Leaf springs are found on most heavy duty trucks and jeeps. These springs are produced using many layers of metal linked together to equal one unit. Torsion bars are a set of bars that twist to provide stability for the vehicle. Like leaf springs, torsion bars are usually applied to heavy duty trucks. Air springs are another type of automotive spring. This suspension component uses air in a chamber that is set in between the car's wheel and frame. All of these springs act in the same way, but have their pros and cons. With any suspension, these components take daily abuse. Depending on the roads and how often one drives, the springs should be checked every so often.
Automotive suspension damperswork in conjunction with the vehicles springs to provide stability. Dampers, also called shock absorbers, are necessary for the car to function properly. A spring isn't very good at the controlling the rate at which it handles the road's surface. The Zcar's shock absorbers control the spring's motion. The damper slows down and decreases the impact of the vibration. When the vehicle feels an unwanted motion, the springs will either compress or decompress, and then send that energy to the damper. The damper then controls the energy to provide the vehicle its desired stability. A typical sign of a blown shock absorber is when the car goes up or down at an increased rate and height.
Anti-sway bars give the vehicle even more stability. These bars work with the vehicles shock absorbers. The anti-sway bar is used on the front and the rear of the car's suspension. They connect one side of the car's suspension to the other, reducing sway. Nearly all vehicles are outfitted with front and rear sway bars today.
The aftermarket industry of automotive suspension is large. Upgraded options including anti-sway bars, coilover kits, spring, shock absorbers, strut bars, and lift springs are all offered in one way or another. Aftermarket sway bars are usually thicker than factory to provide a more rigid and strong suspension. Coilover kits provide a way of lowering the vehicle to enhance drivability, stability, cornering, and appearance. These kits consist of a spring and shock as one assembly. Sometimes this can be a harsh ride, but it does provide great drivability. Aftermarket springs also lower the vehicle, but they do not include a shock absorber. When buying aftermarket suspension springs, the factory shock absorbers should be upgraded as well because they will wear out much quicker from the lower ride height. Strut bars provide the same concept as the anti-sway bars. These bars connect at the top of the vehicles suspension from one side to the other by a thick piece of metal. Strut bars can be added to either the front or rear of the vehicle's suspension. Aftermarket suspension lift kits are popular for truck enthusiasts. These kits combine the use of springs and shock absorbers to lift the vehicle higher from its current state.
