Mostly all vehicles, from two-wheel motorcycles for 18-wheel trucks and trailers use some sort of suspension system. Suspension system seems to be simple on the surface as it has mainly two major functions. The functions are:
- It supports the weight of the truck.
- Absorbs inconsistencies of the road.
The deeper you look into the components, the more you will find them complicated. Here you can have, the closer look at the working of suspension system and the reason; your truck suspension is to be inspected and maintained.
Fundamental components of Suspension
Every suspension has three fundamental components.
- Springs Truck Suspension
- Dampers Truck Suspension
- Anti-Sway Bars Truck Suspension
Springs Truck Suspension
Springs are well designed to implement balance comfort and handling. There are mainly four types of springs. The most common type of spring is coil springs, specially used in passenger cars and trucks. Lead springs are generally used on trucks and heavy-duty vehicles. The other two types of springs are torsion bars and air springs which are now no more in use.
Dampers Truck Suspension
Spring bounces up and down as the vehicle goes over a bump. The vehicle would continue to bounce up and down due to the energy stored in the spring. So, to stop from bouncing, this energy was to be consumed in some other way. Dampers perform this function by absorbing shocks.
Shock absorbers are also known as snubbers. These snubbers control the unwanted motion of the spring and helps in changing kinetic energy into heat energy by reducing the magnitude of vibratory motions which can be dispatched through hydraulic fluid.
Struts are another dampening structure. Basically, when a shock absorber mounted inside a coil spring, struts provide a dampening function like shock absorbers and also provide structural support for the vehicle.
Anti-Sway Bars Trucks Suspension
Anti-Sway Bars provides additional stability to the truck. Basically, it is used alongside struts or shock absorbers. Anti-Sway Bars is also called anti-roll bar.
It is a metallic rod that spans the whole axle, joining effectively in each side of the suspension together. Anti-sway bars create more level ride and reduce vehicle sway by transferring the movements between the wheels.
Hence, this is the basic knowledge of truck suspension you should always know. If you find your truck or trailer is riding rough, you should seek help from professionals to look at the suspension and get your vehicle smooth sailing back on the road.Share This Post:
