Bow plate spring price _ Chang Technology bow plate spring manufacturer FIG _ bow plate spring ..

Automotive leaf spring suspension system is the most traditional automobile elastic element, as well its reliability, simple structure, short process, low cost and can greatly simplify the structure, etc., resulting in a wide range of applications. Automotive leaf spring is generally a combination of several pieces of unequal length alloy spring steel from a group of approximately equal strength spring beams. In addition to the suspension system, acting as a buffer outside, when it disposed longitudinally in the car, and one end of the frame for fixing the hinge connection, you can take in all the transfer of forces and moments, and decided to track motion of the wheel, serves as a guide role, and therefore must be set no other guide means, in addition automobile spring is the superposition of multiple pieces, when the deformation under load, each piece has a relative sliding friction, resulting in some resistance, prompting vibration damping body, and therefore the use of such structures can not install dampers. However, the lowest energy per unit weight of leaf springs saved, the worst result of the utilization of these materials. More generally leaf spring ε = 60%, less leaf spring ε = 75% ~ 85%. Spend a lot of steel, it weighs account vehicle weight 8 to 9%. Henan production bow plate spring damping system manufacturers Chang Technology Co., Ltd. has a full set of advanced disk production, quality testing equipment. Production facilities are fully automated variable cross-section mill, step-quenching furnace, hot air circulation furnace, three throwing the first shot peening machines, product assembly line, pre-press and so on. In the bow plate quality control and detection, there is a Rockwell hardness machine, metallographic analysis lab, physical and chemical analysis testing room, fatigue testing machine, hydraulic stiffness sorting machines and other equipment. These equipment and testing methods to ensure the quality of the Nissan leaf spring.
