This is mainly due to the following reasons.
(1) excessive use of emergency braking. In mountainous areas, the use of emergency braking downhill prone to fracture of the front plate. Because take the brake, the car carrying forward quality most, borne by the front spring fatigue, so easily lead to spring break. It is recommended to use exhaust brake with less emergency braking.
(2) the front wheel brake adjustment tight, if the rear wheel braking efficiency is poor or sudden problems, take the emergency brake, the front spring gets too big impact and fracture.
(3) the road surface is not good, overloading, speeding, so that the front plate spring impact force is too large, easy to cause fracture.
(4) the front plate spring of the North Ben V3 fittings is often overloaded, used for a long time, the elasticity and rigidity are reduced, and the fatigue is broken.
(5) the replacement of the quality of the steel plate spring, the blade bending is not up to standard, the steel plate material is not good or heat treatment is not good, resulting in uneven stress and fracture.
In order to prevent the first V3 and two pieces of steel plate spring break, it is recommended to adopt the following measures:
(1) check and maintain on time to ensure good lubrication of V3 parts spring.
(2) correct adjustment of vehicle braking.
(3) the use of emergency braking, engine exhaust brake.
(4) turning, turning can not be in a hurry.
(5) when replacing the steel plate blade, it is necessary to choose the high quality to ensure its compliance
(6) load uniform, not biased, not overload.
(7) in uneven road, downhill, should control the speed.
