  • Patent number: 7100910
    Abstract: A fluid-filled vibration-damping mount of suspension type, wherein a lower open-end of a second mounting member is fluid-tightly closed by a first mounting member and a tapered elastic body interposed therebetween. An upper open-end portion of the cylindrical portion is closed by a flexible layer for forming a fluid chamber between the elastic body and the flexible layer, which is divided by a partition member into a pressure-receiving chamber defined by the elastic body and an equilibrium chamber defined by the flexible layer, which are mutually communicated through an orifice passage. A pair of elastic restricting projections bonded to the partition member at respective circumferential positions with a circumferential length smaller than a half of a circumference of the partition member, project toward a circumferential region defined between the elastic body and the second mount member, for narrowing the region.

  • Patent number: 7097185
    Abstract: A suspension cross member has a bulkhead interposed between an upper member plate and a lower member plate in such a manner as to extend longitudinally rearward from a disconnection initiating point on a forward arm side along an inner side of the upper member plate and an inner side of the lower member plate. The bulkhead is joined to the upper member plate and the lower member plate, respectively.

  • Publication number: 20040140659
    Abstract: A suspension cross member has a bulkhead interposed between an upper member plate and a lower member plate in such a manner as to extend longitudinally rearward from a disconnection initiating point on a forward arm side along an inner side of the upper member plate and an inner side of the lower member plate. The bulkhead is jointed to the upper member plate and the lower member plate, respectively, at least in the disconnection initiating point.
