摘要： There is disclosed a member for use with an arm that is used as an automobile suspension arm, for example. The member comprises a rodlike body and bushing-mounting portions formed at both ends of the rodlike body. The rodlike body consists of a hollow tube fabricated by extruding an aluminum material into a circular cross section. The bushing-mounting portions are formed by welding bushing-mounting members to both ends of the rodlike body. Each bushing-mounting member has a hole in which a bushing is mounted with a press fit. The curved wall of the rodlike body is recessed at the longitudinal center of the rodlike body. When an automobile having the aforementioned member collides, an axial compressive load is applied to the rodlike body. The rodlike body buckles at the recessed portion. This mitigates the impact in the collision.

摘要： An arm member is used as, for example, a suspension arm of an automobile. The arm member comprises a main body made of a pipe member and a coupling member having a connecting portion. The pipe member is made of aluminum or its alloy. The coupling member is made of aluminum and includes a bushing mounting portion for mounting a vibroisolating bushing. The thickness of the peripheral wall of the end portion of the main body is increased in thickness to have a thickness thicker than that of the other portion of the main body. The connecting portion is abutted to the peripheral wall of the end portion to form an abutted portion, and connected thereto at the abutted portion. Thus, the coupling member is coupled to the main body.

摘要： The mounting component for a cylindrical bushing is comprised of a holder into which a cylindrical bushing can be fitted. An opening is formed at one location in a circumference direction of the holder such that the opening extends in an axial direction. At the opening, the holder can be opened in an expanding manner. When the opening is closed, the inner circumference surface of the holder is tightly attached to the outer circumference surface of the bushings to effect a clamping fastening method wherein the bushing is fitted and fixed inside the holder. Joints are provided on the two opening edges, or in their vicinity, of the aforementioned opening, in such a way that the joints protrude toward the outer circumference surface, These joints are bonded by a coupling structure using plastic deformation, and thus maintain the opening in a closed state.

摘要： A process for producing a vibration isolator includes the steps of preparing an axial member, an outside member, the outside member including a cylinder-shaped portion and a bracket having a hollow, and a cylinder-shaped rubber elastic member, and drawing the cylinder-shaped portion by inserting a stationary mold, with which a drawing apparatus is provided, into the hollow of the outside member so that an outer peripheral surface of the cylinder-shaped portion contacts with the stationary mold, by disposing the rubber elastic member and the axial member inside the cylinder-shaped portion, and by pressing the cylinder-shaped portion onto the stationary mold and simultaneously diametrically reducing the cylinder-shaped portion to plastically deform the same. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

摘要： A process for producing a vibration isolator. The process involves steps of forming an intermediate product including an axial member, an outside member having a cylinder-shaped portion and a rubber elastic member, and drawing the cylinder-shaped portion with a drawing apparatus provided with a drawing hole at least by pressing the cylinder-shaped portion into the drawing hole. The drawing hole has a predetermined dimensional diameter being smaller than an outer peripheral diameter of the cylinder-shaped portion. Thus, the cylinder-shaped portion is reduced diametrically to plastically deform. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

摘要： A crosslinked elastomer body is composed of an electrically conductive composition comprising an electrically conductive filler and an insulative elastomer (matrix). The electrically conductive filler is in a spherical particulate form and has an average particle diameter of 0.05 to 100 μm. The electrically conductive filler has a critical volume fraction (φc) of not less than 30 vol % as determined at a first inflection point of a percolation curve at which an insulator-conductor transition occurs with an electrical resistance steeply reduced when the electrically conductive filler is gradually added to the elastomer. A resistance observed under compressive strain or bending strain increases according to the strain over a resistance observed under no strain when the electrically conductive filler is present in a volume fraction not less than the critical volume fraction (φc) in the composition.

摘要： A fluid-filled elastic mount (10) wherein a fluid-tight space (40) defined by two mounting members (12, 14), an elastic body (16) and a flexible diaphragm (36) is divided by a partition member (34) into pressure-receiving and an equilibrium chambers (44, 46) communicating with each other through a first orifice (64). The partition member has a communication hole (62) for fluid communication of the first orifice with the equilibrium chamber. The elastic mount has a cover member (76) which cooperates with the diaphragm to define a space in which a pushing member (84) is accommodated such that it is pressed onto the diaphragm by a biasing member (86), so that the diaphragm closes the communication hole. The pushing member cooperates with a rubber plate (94) to divide the space within the cover member into static pressure and operating chambers (96, 100), and the pushing member is sucked toward the cover member by a negative pressure applied to the operating chamber, so that the diaphragm is displaced away from the communication hole to open the same for fluid communication of the orifice with the equilibrium chamber.
