The invention provides a hydraulic bushing and an automobile. The hydraulic bushing comprises a runner plate; two hollow cavities and a runner groove communicated with the two hollow cavities are formed in the rubber main spring; a runner plate is mounted in each hollow cavity, and the inner side of each runner plate is matched with the corresponding hollow cavity to form a liquid chamber; the outer side of the rubber main spring and the outer side of the runner plate abut against the inner wall of the outer pipe, and the runner plate is matched with the runner groove to form an inertia channel communicating the two liquid chambers. A dynamic adjusting assembly is arranged in the inertia channel. According to the hydraulic bushing, the low-frequency large-damping performance is provided through the non-decoupling type channel, the low-dynamic-stiffness performance is provided by changing the liquid flowing direction and flow through the decoupling type channel, use of the dynamic adjusting assembly is controlled, indoor and outdoor pressure of liquid reaches dynamic balance, rigidity decoupling of the hydraulic bushing is achieved, and the needed low-frequency-band performance and high-frequency-band performance are obtained; and vibration and noise reduction are facilitated.
本发明提供了一种液压衬套及汽车,该液压衬套包括流道板;橡胶主簧上设有两个空心腔和一个连通两个空心腔的流道槽;每一空心腔内安装有一流道板,每一流道板的内侧与一空心腔配合形成一液体室;橡胶主簧的外侧和流道板的外侧与外管的内壁相抵接,流道板和流道槽相匹配,形成连通两个液体室的惯性通道;惯性通道内设置有动态调节组件。本发明中,通过非解耦式通道提供低频大阻尼性能,通过解耦式通道改变液体流动方向和流量来提供低动刚度性能,控制动态调节组件的使用,使液体室内外压力达到动态平衡,实现液压衬套刚度解耦,获得所需要的低频段和高频段性能,有利于减振降噪。
