The leaf spring acts as a buffer in the truck suspension system, as well as the transmission of all the forces and torques, as well as the trajectory of the wheels, and plays a guiding role. Compared to the airbag suspension, leaf springs are widely used on trucks because of their simple structure, low cost and convenient maintenance.

Abnormal use and lack of good maintenance consciousness during the operation of the vehicle will lead to premature damage to the leaf springs. Here's a summary of some of the reasons that led to the damage of leaf springs and how to avoid such situations.

Vehicle overloading for a long time

Baotou beiben heavy truck parts of steel plate spring was originally based on the vehicle design load quality to design, if the overload condition for a long time, spring will be over bending stress, the leaf spring fatigue strength decreased, so easy to make the spring break. Overloading will not only cause damage to the leaf springs, but also cause damage to the engine, transmission parts and excessive wear of the tires.

Proposal: try to ensure that the vehicle is not overloaded, partial load, and give full play to the performance of vehicles.

Travel speed is too high

The vehicle is driven at an economic speed, which ensures both safety and fuel savings. However, some of the vehicle speed is too high, especially in the poor road on the road, will lead to Baotou North Heavy spare parts, leaf spring deformation amplitude increases, frequency increases, so that the leaf spring accelerated damage. The situation is in the dump truck on the truck in the earth and most of the construction site work, traffic is bad, some drivers one-sided pursuit of economic efficiency, overload, high speed, acceleration of the car body fatigue also caused damage, also this kind of driving habits are not safe.

Recommendation: vehicles in low road sections should be vulgar driving, especially when vehicles pass, slow down ahead of time, stop the case with the brake ditch.

The speed of a vehicle on a curved road

When the vehicle in cornering, will produce a large centrifugal force, such as turning and shortness of large centrifugal force and increase the outside of the vehicle plate spring load, resulting in Baotou beiben heavy truck parts spring deformation caused by the lateral plate spring force is too large, the fatigue and fracture.

It is recommended that the vehicle should slow down during the cornering, at the best speed at low speed and medium speed, which is both safe and able to reduce vehicle failure.
