降噪和减振润滑油(脂)

可应对汽车噪声和振动问题的润滑剂

相比于过去,现今的汽车在设计方面注重提供更平稳的驾驶感和更安静的车内环境。正因为如此,现在大家更加关注以前未注意到的微弱噪音和轻微响动问题。

噪声、振动与声振粗糙度 (NVH) 以及嗡嗡声、吱吱声和嘎嘎声 (BSR) 可能由许多内部和外部零部件发出。这些来源可能包括橡胶在涂层、金属在塑料、及皮革与皮革之间的摩擦或来自于发动机。

Norbert® 高性能润滑剂是解决 NVH 和 BSR 的理想之选,因为其可:

  • 通过喷涂或刷涂轻松应用
  • 不受雨、雪、冰、盐、灰尘和污垢等恶劣条件的影响
  • 耐燃料、冷却剂、制动液和洗涤液
  • 在汽车的整个寿命周期都低蒸发或不会出现特性变化
  • 与所有其他可能接触的物质和表面兼容

满足驾驶员和乘客的期望

受客户需求的推动,汽车制造商多年来一直试图通过各种被动设计技巧和主动技术特性来降低 NVH 和 BSR。

降噪和减振性能是新购车者的主要考虑因素 — 特别是随着 EV(电动汽车)的出现 — 并且往往会影响购车者对汽车质量和价值的看法。除了明显的令人感到烦扰,购车者想要购买安静、驾驶平稳的汽车还有许多重要原因。

其中包括:

  • 低频和中频噪音会极大地导致驾驶疲劳
  • 高频率噪音会限制人们在车内听到谈话的能力
  • 噪音会引起头痛、压力和烦躁
  • 振动会引起烦躁和不适

Norbert® 汽车润滑剂适用于哪些场合?

Norbert® PFPE 润滑剂在汽车中的应用场合一般分为两类:

引擎盖下

鉴于空气动力学要求更严密的封装,并且较大的引擎被较小的涡轮增压引擎和机械增压引擎替代以提升燃油效率,引擎盖下温度正逐渐上升。由于引擎盖下的环境温度超过 120°C (248°F),需要 PFPE 润滑剂的汽车应用场合也在不断增加,包括:

  • 交流发电机传动轮的超速去耦器
  • 前端附件传动装置 (FEAD) 张力器和惰轮
  • 节气门体轴承
  • 废气再循环 (EGR) 阀
  • 进气歧管密封件和执行器
  • 风扇离合器轴承
  • 燃油系统排放控制阀
  • 电动冷却系统泵和阀
  • 点火系统塞帽

汽车内外部噪声、振动与声振粗糙度 (NVH)

Norbert® 润滑剂是消除汽车车厢内外嗡嗡声、吱吱声和嘎嘎声 (BSR) 的长期高效解决方案。这些 PFPE 润滑油和润滑脂可以有效减少各表面之间摩擦产生的噪声,以及机械振动产生的噪声,且不会导致任何材料兼容性问题或产生有害挥发性有机化合物 (VOC)。部分应用包括:

  • 挡风雨条和弹性体密封件
  • 内部塑料、金属和皮革表面
  • 中控台铰链和插销
  • 车门和后备箱闩锁系统
  • 制动踏板总成
  • 座椅装置(滑轨、头枕铁杆和锁)
  • 电动开关
  • 气囊弹簧
  • 外后视镜
  • 悬架衬套
