The invention provides an engine mount for an automobile, comprising: a base mounted on an automobile body; the accommodating part partially extends out of the base, is connected with an engine of the automobile and is suitable for accommodating a magnetorheological medium; the edge of the valve body is combined with the inner wall of the containing part so that the containing part can be divided into two medium cavities communicating with each other in the height direction, and a first flow channel, a second flow channel and a third flow channel are formed in the valve body; under the condition that the amplitude of the containing part is smaller than the preset amplitude, the magnetorheological medium passes through the second flow channel or the third flow channel and flows to the valve body from one of the two medium cavities with the larger pressure intensity, so that the pressure of the magnetorheological medium in the two medium cavities is balanced; under the condition that the amplitude of the containing part is larger than or equal to the preset amplitude, the magneto-rheological medium overflows the second flow channel or the third flow channel and flows between the two medium cavities through the first flow channel, and the damping force of flowing of the magneto-rheological medium is adjusted by changing the magnetic field intensity flowing through the first flow channel.
本发明提供了一种用于汽车的发动机悬置,包括:基座,安装在汽车的车身上;容纳部,部分地伸出基座,并与汽车的发动机连接,适用于容纳磁流变介质;以及阀体,阀体的边缘与容纳部的内壁结合,以将容纳部分割为在高度方向上相互连通的两个介质腔,阀体内部形成有第一流道、第二流道以及第三流道;在容纳部的振幅小于预定振幅的情况下,磁流变介质经第二流道或第三流道,由两个介质腔中压强较大一个流向阀体,以平衡两个介质腔中的磁流变介质的压力;在容纳部的振幅大于等于预定振幅的情况下,磁流变介质溢出第二流道或第三流道,经第一流道,在两个介质腔之间流动,并通过改变流经第一流道的磁场强度,以调整磁流变介质流动的阻尼力。
