The invention provides a hydraulic bushing, a vibration reduction structure and an automobile, in the hydraulic bushing, runner plates are assembled in a rubber main spring, a liquid chamber is formed between the inner side of each runner plate and the rubber main spring, and the outer sides of the runner plates abut against the inner wall of a bushing outer pipe; the flow channel plates are provided with flow channels communicated with the liquid chambers, the flow channels on the two flow channel plates are communicated, and liquid is packaged in the liquid chambers and the flow channels; an inner ball cage is arranged in the rubber main spring and corresponds to the runner plate; two connecting channels are further arranged in the rubber main spring, and each connecting channel is used for communicating the two liquid chambers. Liquid in the liquid chamber not only can flow in an inertia channel formed by the two flowing channels, but also can flow in an orifice channel of the two connecting channels, so that the dynamic stiffness of the hydraulic bushing under high-frequency small vibration can be effectively reduced, the damping angle is increased, the comfort is improved, and vibration is effectively attenuated.
本发明提供了一种液压衬套、减振结构及汽车,该液压衬套内,流道板装配在橡胶主簧内,每一流道板的内侧与橡胶主簧之间形成一液室,流道板的外侧与衬套外管的内壁相抵接;流道板上设置有与液室连通的流动通道,两个流道板上的流动通道相连通,液室和流动通道内封装有液体;橡胶主簧内设置有内球笼,内球笼与流道板相对应;橡胶主簧内还设置有两条连接通道,每一连接通道用于连通两个液室。液室内的液体不仅可以在两个流动通道形成的惯性通道内流动,还可以在两条连接通道的孔口通道内流动,可有效降低高频小振动下的液压衬套动刚度,增加阻尼角,增加舒适性的同时有效衰减振动。
