空气弹簧是减振降噪的核心技术。常规的螺旋弹簧和板簧都是金属件,被替换成空气弹簧之后整车的噪声及振动特性都会得到大幅改善。跟板簧相比,空气弹簧还有装配方便的优势。此外,空气弹簧可以调节行驶高度,例如降低公交车地板高度或者平衡卡车因载荷不均匀所导致的车身高度不一致,使底盘一直保持最佳高度(图1)。 Air spring is the core technology of vibration and noise reduction. Conventional coil springs and leaf springs are metal parts, and the noise and vibration characteristics of the vehicle are greatly improved after being replaced by the air spring. Compared with the leaf spring, air springs also have the advantage of easy assembly. In addition, the air spring can adjust the ride height, such as reducing the height of the bus floor or balancing the inconsistent height of the truck due to uneven load, keeping the chassis at the optimum height (Figure 1).
