Heavy vehicle sub-chassis springs; Application, types and important points in choosing springs
A spring is one of the most important components in the sub-chassis and suspension systems of heavy vehicles, which plays a very important role in bearing the weight of the vehicle, absorbing shocks and maintaining the vehicle’s balance. Trucks, trailers, tractors and other heavy vehicles, due to their high weight and carrying heavy loads, bear a lot of pressure during movement. Having a high-quality spring that is suitable for the vehicle’s specifications allows part of this pressure and shocks to be controlled and the vehicle’s suspension system to function more optimally.<\/p>\n\n\n\n
What is a spring and what is its function?
A spring is a mechanical component that is used to bear force, absorb shock and control movements caused by uneven road surfaces. In heavy vehicles, the spring usually works in conjunction with the chassis and suspension system and is responsible for bearing the weight of the vehicle and the load and preventing the direct transmission of road shocks to the chassis and other vehicle components.<\/p>\n\n\n\n
When a truck or trailer passes over rough roads, bumps, and poor roads, a lot of force is applied to the wheels and suspension system. The spring absorbs some of this force with its flexibility, making the vehicle\u2019s movement more controlled and stable. For this reason, the health of the spring has a direct impact on the performance of the suspension system and the quality of the vehicle\u2019s movement.<\/p>\n\n\n\n
The importance of springs in heavy vehicles
In heavy vehicles, the weight of the vehicle and the load that can be carried is much greater than in passenger cars. For this reason, the suspension system components, including the spring, must be able to withstand more forces. A heavy vehicle spring must be selected according to its weight, type of use, vehicle model, and load capacity, and we at Mohsen Haddad Trading value this.<\/p>\n\n\n\n
An unsuitable or worn spring may not be able to properly support the weight of the vehicle. In such circumstances, in addition to reducing the performance of the suspension system, more pressure is placed on other components under the chassis. Also, changing the height of the vehicle, reducing balance, creating noise and increasing pressure on some components of the suspension system can be signs of a problem with the spring.<\/p>\n\n\n\n
Types of springs used in heavy vehicles
The springs used in heavy vehicles are produced in different models according to the design of the suspension system, the type of vehicle and the amount of load carried by the vehicle. The most important types of springs include leaf springs and some models of springs used in various suspension systems.<\/p>\n\n\n\n
Leaf springs are one of the well-known parts in the suspension system of many heavy vehicles. This type of spring usually consists of several layers or metal blades placed next to each other. The design and number of spring blades can vary depending on the type of vehicle and load-bearing capacity.<\/p>\n\n\n\n
Choosing the right spring should be based on the exact specifications of the vehicle. Using a spring whose load-bearing capacity does not match the vehicle’s operating conditions can reduce the life of the part and create additional pressure on other components of the suspension system.<\/p>\n\n\n\n
Signs of spring damage or wear
Like other car parts, springs may wear out due to long-term use, carrying heavy loads, continuous driving on unsuitable roads, and severe impacts. Observing cracks or breaks, deformation, lowering the height of one side of the car, making unusual noises, and reducing the balance of the car can be signs that indicate the need to check the springs.<\/p>\n\n\n\n
If one of the spring components is broken or seriously damaged, continuing to use the car can cause more pressure to be placed on the suspension and sub-chassis system. For this reason, it is better to have the condition of the spring and other related parts checked by a specialist repairman if you notice any unusual symptoms.<\/p>\n\n\n\n
Guide to Buying a Heavy Vehicle Sub-Chassis Spring
When buying a sub-chassis spring, special attention should be paid to the technical specifications of the car and the type of suspension system. The car model, load capacity, spring dimensions, thickness, length, number of blades, and other technical specifications are among the factors that can affect the selection of the appropriate spring.<\/p>\n\n\n\n
One of the common mistakes when buying a spring is choosing a product based solely on its appearance or price. Two springs may look similar but differ in thickness, material, number of blades, or force-bearing capacity. Therefore, it is better to match the technical specifications of the part with the model installed on the vehicle or the vehicle’s technical information before purchasing.<\/p>\n\n\n\n
What is the importance of spring quality?<\/p>\n\n\n\n
The quality of a spring’s construction has a great impact on its durability and performance. A spring that is made from suitable raw materials and with a standard production process can perform better in harsh working conditions. Heavy vehicles usually operate on the road for many hours and are constantly affected by load, vibration, and impact; therefore, using high-quality parts for the suspension system is very important.<\/p>\n\n\n\n
A high-quality spring must be able to maintain its strength and flexibility within the specified working range. Also, the precise dimensions and surface quality and construction of the part are factors that can affect its lifespan.<\/p>\n\n\n\n
The role of springs in maintaining vehicle balance
Another important function of springs is to help maintain vehicle balance while driving. When the vehicle is traveling over rough terrain or carrying a heavy load, the suspension system must control the vertical movements of the vehicle. The spring plays an important role in this process and helps maintain the proper distance between the chassis and the axle.<\/p>\n\n\n\n
If the spring becomes weak or damaged, the vehicle’s height may change or one side of the vehicle may be lower than the other. Such conditions can negatively affect the vehicle’s stability and performance. Therefore, periodic inspection of the suspension and spring system is very important for heavy vehicles.<\/p>\n\n\n\n
