DNT tool teaches you how to avoid damage to truck leaf springs
Leaf springs play a buffering role in the truck suspension system, and are also responsible for transmitting all directional forces and torques, as well as determining the trajectory of wheel movement and playing a guiding role. Compared with airbag suspension, leaf springs are widely used on trucks because of their simple structure, low cost and convenient maintenance. During vehicle operation, abnormal use and lack of good maintenance awareness will cause premature damage to leaf springs. Below, DNT tool summarizes some of the reasons that cause leaf spring damage and how to avoid such situations.
1. Long-term vehicle overloading
Leaf springs were originally designed according to the vehicle's designed loading mass. If they are in an overloaded state for a long time, the leaf springs will be subjected to excessive bending stress, causing the fatigue resistance strength of the leaf springs to decrease, which will easily cause the leaf springs to break. Overloading will not only damage the leaf springs, but also cause certain damage to the engine and transmission system components and excessive wear of the tires.
Suggestion: Try to ensure that the vehicle is not overloaded or unbalanced, and reasonably exert the performance of the vehicle.
2. Driving speed is too high
Driving at an economical speed can ensure safety and save fuel. However, if some vehicles drive too fast, especially on poor roads, the deformation amplitude of the leaf spring will increase, the frequency will increase, and the leaf spring will be damaged faster. These situations are more common on dump trucks. Most dump trucks are operated on earthwork and construction sites. The road conditions are relatively poor. Some drivers pursue economic benefits unilaterally, overload, and drive at high speed, which accelerates the fatigue of the car and causes damage to the body. In addition, such driving habits are not safe. Suggestion: Vehicles should drive at a low speed on bad roads, especially when crossing a ditch, slow down in advance, and avoid crossing the ditch with brakes.
3. Driving speed of vehicles on curved roads
When a vehicle is turning, it will generate a large centrifugal force. For example, if the turn is too sharp, the large centrifugal force will increase the load on the outer leaf spring of the vehicle, which will cause the leaf spring to deform, causing the outer leaf spring to be overstressed and fatigued and broken. Suggestion: The vehicle should slow down when turning, and the best speed is low speed or medium speed, which is safe and can reduce vehicle failure.
