用于舒适功能的新型免维护滑动轴承KS P180

科尔本施密特有限公司

(PresseBox) (Neckarsulm, )
SUV车型的发展趋势正在不断延续,同时驱动系统的电动化也在大步迈进。两大因素推高了车辆的重量,也导致汽车底盘和外部区域的滑动轴承承载增大。而在内饰方面,则面临着电动化所带来的另一个完全不同的挑战:近乎完全无噪音的电动行驶对于减振器、阀门、执行器和车内无数的轴颈部位在噪声、振动与声振粗糙度方面提出了更高要求。这些零部件无噪音的运转对于车内乘坐者的舒适感起着决定性作用。如今,科尔本施密特滑动轴承有限公司为这些应用特别推出了一款全新免维护滑动轴承KS P180,通过减少粘滑效应,可以减少噪音,此外还在边缘支撑上具备更高的承载能力。

车辆中可以感受到和可以听到的振动都归纳在NVH(噪声、振动与声振粗糙度)这一概念内。使用电驱动方式车辆的车内NVH水平面临新的舒适要求:随着内燃发动机的消失,乘坐者对噪音的感知也发生了变化。类似嘎吱嘎吱这样的干扰噪声显得非常突出。这些噪声主要是由部件及其轴承内的粘滑效应所产生的,粘滑是通过高度静摩擦和摩擦突然中断而产生的。随着车辆使用年份的增加,这种噪音生成大多情况下也会增多,因为在轴承结构中会产生磨损现象或者润滑剂会发生老化。为了避免这种粘滑效应的产生,持续保持低摩擦水平和低度静摩擦至关重要。使用新型KS P180滑动轴承可以在整个使用寿命内使摩擦保持在低水平,因此,新产品是适用于以上所描述应用场景的最佳选择。

低摩擦水平和高承载能力

尽管轻量化趋势不断推进,但是确切来说车辆的平均重量仍在增加。其中的因素也包括电动化的不断增长,例如混合动力车中增加了新的驱动组件,但是主要影响来自大重量的电池系统。较高的车辆重量尤其给悬挂系统的部件带来更大的负荷,例如会造成减振器横向力的显著提升,结果导致活塞杆更大程度的弯曲,在轴颈部位出现高的边缘负载。KS P180型产品采用一种新型的青铜结构和在摩擦学上进行优化的PTFE复合材料,通过两者结合,在承载能力方面,尤其在边缘承载能力方面,远远胜过至今为止市场上所供应的PTFE轴承。KS P180型产品凭借低摩擦系数确保了更长的使用寿命,为对于行驶舒适性而言十分重要的减振器功能提供了解决方案。
