期凯孚轴承倾力推出低噪音转向管柱轴承
发布日期：2024-02-07
中轴网记者获悉，日前斯凯孚轴承宣布，其为转向柱开发了一种新定制的轴承——低噪音转向管柱轴承。凯孚轴承倾力推出的此类轴承能够大幅降低噪音级。预紧线圈转向管柱轴承（P-WSCB）旨在满足一级供应商的需求，同时帮助他们满足整车制造商（OEM）对低噪音的需求。
降低车辆分系统的噪音是当前汽车制造业的一大趋势，过量噪音常常被客户和最终用户视为故障，而低噪音则被视为优质和舒适的标志。一级供应商和整车制造商往往对运行噪音相对较低的轴承的耐用性和总体性能抱有更大的信心。
斯凯孚轴承汽车部转向和悬架系统业务及产品开发经理 Andrea Griseri 对新产品评论道： “这款低噪音轴承完善了斯凯孚转向管柱轴承组合。 与标准斯凯孚轴承相比，此类低噪音轴承使噪音级降低了约 4 加权分贝（4dB(A)），而与竞争者的产品相比，其降低的噪音级甚至不止 4 dB(A) 之多。 并且其能够在保持现有高性能特征的情况下降低噪音。”
线圈滚道内的间隙为轴承外圈提供了灵活性，使其能够压合装入外壳内。 间隙的用心设计使轴承噪音得到降低。 其它较低噪音的重要设计特点包括： 内圈粗糙度的降低；球体质量等级的变化；以及润滑油量的优化。
记者还了解到，单就摩擦力矩和转向管柱刚度方面而言，该轴承能够为驾驶员提供更舒适的驾车体验；而且同时，还可以为驾驶员减轻车辆由道路引起的振动感，提升其舒适程度。其能够良好地支撑轴向和径向载荷，并提供导电性，而该性能可协助安全气囊及其它电气部件平稳运行，我们猜测这将会加入后来汽车产业的工作当中。
