The trailer suspension is a mechanical hardware system that keeps the wheels from touching the trailer body. It also enables steering stability and increases friction between the road and the tires. The entire system comprises of tires, springs and linkages. Depending on the type of springs, trailer suspension in Prestons and elsewhere can be classified into four main types such as:
Trailing-Arm Suspension
Previously seen only in aircraft, these types of suspension are now being widely used in ground vehicles. It consists of an arm that connects the trailer axle to the chassis’ pivotal point. The trailing-arm suspension unit helps the wheels move independently and vertically, thus enhancing comfort.
Rubber Suspension
The rubber suspension springs offer more comfort during the ride by reducing metal-to-metal contact and lowering the amount of noise made during movement. The rubber trailer suspension also helps reduce the need for lubrication.
Leaf Springs
One of the most traditional types of suspensions, the leaf spring acts as a shock absorber for lightweight trailers. But these are not recommended for heavy-duty vehicles.
Air Suspensions
The air suspensions consist of air-filled bladders that supplement the springs of a trailer. These help adjust driving conditions according to the height and firmness of the vehicle.
How to Identify Problems in the Suspension System
If you are having a bumpy ride on rocky terrain, it is understandable. But what if the same happens when you are driving on a flat road? Something must be the matter, right? While the first thing that comes to a driver’s mind is the low air pressure in the tires. But sometimes, these frequent bumps and shocks might also point toward a faulty suspension system. You should get it examined by an efficient truck mechanic in Eastern Creek and learn what the problem is. Some other signs of suspension system issues are, tires wearing out faster than expected, the trailer bending low on one side, or oil leaks in the suspension. Get the trailer inspected by expecting mechanics to identify and resolve the problem before it escalates.
