摘要： A cylindrical vibration isolating device that prevents damage to a vibration isolating rubber and cracks in a welded portion of a sub-frame. The sub-frame mount comprises an outer cylinder, an inner cylinder connected by the vibration isolating rubber. Small and large diameter portions are provided on a lateral wall of a barrel portion of the outer cylinder. Between the small and large diameter portions is formed a step-like boundary portion. The height in the axial direction of the boundary portion changes in the circumferential direction and has a substantially mountain-like shape with a top projecting in the press fitting direction. A contact area of the large diameter portion contacting a mounting hole of the sub-frame is increased in accordance with an amount of the press fitting. Therefore, when the sub-frame mount is press-fitted into the mounting hole of the sub-frame, the press fitting load is gradually increased.

摘要： The object of the present invention is to prevent damages of a vibration isolating rubber and cracks in a welded portion of a sub-frame when press-fitting a sub-frame mount.The sub-frame mount 1 comprises an outer cylinder 2, an inner cylinder 2 and the vibration isolating rubber 4 connecting these outer and inner cylinders. A small diameter portion 10 and a large diameter portion 11 are provided on a lateral wall of a barrel portion of the outer cylinder 2. Between the small diameter portion 10 and the large diameter portion 11 is formed a step-like boundary portion 12. The height in the axial direction of the boundary portion 12 changes in the circumferential direction and has a substantially mountain-like shape with a top 12a projecting in the press fitting direction. A contact area of the large diameter portion 11 contacting a mounting hole 21 of the sub-frame 20 is increased in accordance with an amount of the press fitting. Therefore, when the sub-frame mount 1 is press-fitted into the mounting hole 21 of the sub-frame 20, the press fitting load is gradually increased thereby preventing the rapid rise of the press fitting load.
摘要翻译：本发明的目的在于防止隔板橡胶受到损坏，并且在将副框架安装件压配合时，防止子框架的焊接部分产生裂缝。副框架安装件1包括外筒2，内筒2和连接这些外筒和内筒的防振橡胶4。在外筒2的筒部的侧壁上设置有小直径部10和大径部11。在小径部10与大直径部11之间形成有阶梯状的边界部12。边界部12的轴向高度沿圆周方向变化，并且具有大致山形，其中顶部12a在压配合方向上突出。根据压配件的数量，与子框架20的安装孔21接触的大直径部分11的接触面积增大。因此，当副框架安装件1被压配合到子框架20的安装孔21中时，压配合载荷逐渐增加，从而防止压配装载的快速上升。

摘要： A liquid-filled engine mount is disclosed which includes a rubbery elastic member interposed between an engine and a vehicle body, a diaphragm positioned in opposed relation to the rubbery elastic member. The engine mount defines a liquid chamber therein. The liquid chamber holds an actuating liquid therein. The liquid chamber has a partition wall disposed therein. The partition wall separates the liquid chamber into primary and secondary chambers. The primary chamber is provided on a side of the elastic member while the secondary chamber is provided on a side of the diaphragm. The partition wall has first and second orifices extending therethrough. The first orifice communicates with both the primary chamber and the secondary chamber. The second orifice communicates with the primary chamber. The first and second orifices provide different resistances to the liquid flowing therethrough. The engine mount includes a resilient means for urging the diaphragm against the partition wall to close an opening of the second orifice. The engine mount includes a diaphragm driving means for forcing the diaphragm against a resilient force the resilient means exerts on the diaphragm to thereby open the opening of the second orifice, such that the second orifice communicates with the secondary chamber. The diaphragm has plural projections formed on a surface thereof.
