技术介绍
悬置的性能对汽车乘坐舒适性有着重要的影响,它的好坏直接关系到发动机振动向车体的传递,影响整车的NVH(Noise,VibrationandHarshness)特性。目前,混合动力汽车的开发蒸蒸日上,其发动机频繁地启停以及发动机转速上升率高等特点对汽车乘坐舒适性提出了更大挑战。为了提高燃油经济性,在一些高级轿车中闭缸技术得到运用,在负荷较小时,“气缸按需运行”(CylinderOnDemand)系统会自动关闭某些气缸。该技术的使用不仅增加了振动阶次的多样性,还加剧了发动机受力不均匀的振动问题。现有的几种悬置:(1)液压悬置:液压悬置经过不断改进,结构型式不断变化,主要经历了三代:惯性通道式液压悬置、惯性通道-解耦盘式液压悬置、节流盘式液压悬置。第一代液压悬置在低频时表现为大刚度,高频时,明显存在高频动态硬化现象。第二代由于解耦盘的存在,在中高频阶段刚度低,满足了小刚度的需求,在一定程度上改善了悬置隔振性能。第三代节流盘的使用显著改善了解耦盘引起的动态硬化现象,但是在中高 ...
