How to maintain the early spring leaf
If the vehicle is used improperly or it is not properly maintained, the leaf spring will not be used for a long time and damage will occur. This is not normal, and it is early damage. Early damage of leaf springs is more common in mountain areas. Causes early damage to the vehicle leaf spring mainly due to the following reasons: (1) Vehicles often use leaf springs under overload or partial load. The design is based on the rated load of the vehicle. If the actual load in the use of the vehicle exceeds the rated load of the vehicle, or if the load is severely offset, the steel plate The spring will produce excessive bending stress in the work, which will greatly reduce the fatigue resistance of the leaf spring and cause early damage to the leaf spring. The Steyr trucks carrying coal were most loaded with O43 trucks, and were heavily overloaded and overloaded during use. Individual trucks pulled more than 60 tons. Due to severe overload, the leaf springs were damaged early. According to the regulations, uniform loading will help increase vehicle utilization and will also extend the life of the leaf spring. (2) The vehicle's running speed is too high, especially if it is running on a bad road at a high speed, the deformation range of the leaf spring will increase and the frequency will increase, causing the leaf spring to accelerate fatigue and damage. Here, we advise the user to extend the life of the leaf spring. The vehicle should try to drive at an economic speed, and should drive at a low speed on bad roads. (3) Emergency braking is often used by vehicles. When the vehicle uses emergency braking while driving, due to the action of the inertial force, the leaf spring, especially the front leaf spring, is subjected to excessive bending stress and tensile stress. When the allowable stress is exceeded, the leaf spring breaks. The vehicle should run at medium speed during operation. Exhaust braking of the engine is often used, and emergency braking is rarely used. (4) When the vehicle turns, the speed is too high. If the car turns too quickly, excessive centrifugal force will be generated, which will greatly increase the load on the outer leaf spring and accelerate the damage of the leaf spring. In order to prolong the service life of leaf springs and improve economic efficiency, deceleration should be paid attention when turning. (5) The loosening of the bolts or the loosening of the center bolts of the leaf springs will increase the load of the leaf spring main pieces and cause early damage. In normal maintenance, attention should be paid to the fastening of the bolts for riding and the center bolts. Replace them if damaged. (6) The poor lubrication of the leaf spring and the failure of the shock absorber can cause early damage to the leaf spring. Usually pay more attention to maintenance and lubrication. Shock absorber failure should be repaired and replaced if damaged.
