Vehicle operation, the use of non normal and lack of good maintenance awareness, which will cause damage to the steel plate spring. The following summarizes some of the causes of the damage to the steel plate spring, and how to avoid such a situation.
Vehicle long time overload
North Benz V3 accessories steel plate spring was originally based on the vehicle design load quality to design, if the overload condition for a long time, beiben V3 accessories spring will be over bending stress, the leaf spring fatigue strength decreased, so easy to make the spring break. Overload will not only cause damage to the leaf spring, but also cause the engine and transmission parts to be damaged.
Recommendation: as far as possible to ensure that the vehicle is not overloaded, partial load, reasonable to play the performance of the vehicle.
Travel speed is too high
Vehicles to economic speed, both to ensure safety, but also to save oil. But some vehicles traveling speed is too high, especially on the poor road, will lead to the deformation of the steel plate spring, the frequency increase, so that the steel plate spring to accelerate 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 the bad road should be vulgar, especially when the vehicle over the ditch, in advance to slow down, stop with the brake off the ditch.
Vehicle at a roundabout speed
When the vehicle in cornering, will produce a large centrifugal force, such as turning and shortness of large centrifugal force and increase of vehicle accessories V3 beiben lateral plate spring load, and spring deformation caused by the lateral plate spring force is too large, fatigue and fracture.
Suggestion: the vehicle should slow down, when cornering at low speed, medium speed for optimum speed, which is safe, and can reduce the vehicle fault.
