Patent number: 8794608Abstract: To provide a vibration isolation apparatus which prevents a vibration isolation leg from being pushed by a resin material injected in a resin molding process and to prevent generation of resin burrs. Because a rubber notch is formed in a first molding product, when the first molding product is placed in a resin mold in an insert molding process, the pressure of the flowing resin material injected in the resin mold through the injection gate can be relieved and thus first wall covering rubber parts may be less pushed by the resin material. This reduces positional deviation of a vibration isolation leg and sealing errors caused by deformation of the first wall covering rubber parts, and thus generation of resin burrs can be suppressed.Type: GrantFiled: December 8, 2011Date of Patent: August 5, 2014Assignee: Toyo Tire & Rubber Co., Ltd.Inventor: Hironori Kato

Patent number: 7278633Abstract: A hydraulic antivibration device arrangement capable of achieving a downsizing and weight reduction, and a reduction of booming noise by suppressing a reaction force to impingement upon stopper action is provided. By disposing a protuberant rubber portion 35 at an upper end of a main body member 2, its spacing distance from a roll center can be lengthened, the reaction force to impingement can be diminished, and input load to the main body member 2 can be diminished. Consequently, reduction of rigidity and strength required for respective components as well as enhancement of durability is possible, which permits to make the components thin-walled thereby making a hydraulic antivibration device arrangement 100 lightweight as a whole. Diminishing of such reaction force upon stopper action also enables vibrations input through a car body side bracket 120 to the body frame to be suppressed, thereby reducing the generation of booming noise.Type: GrantFiled: December 24, 2004Date of Patent: October 9, 2007Assignee: Toyo Tire & Rubber Co., Ltd.Inventors: Hikofumi Yamamoto, Yukio Takashima

Patent number: 7048265Abstract: A mount assembly having a support structure mounted to a frame of a vehicle and a carrier mounted to a vehicle body. The support structure is displaceable relative to the carrier along a line of travel. An insulator is disposed between the support structure and the carrier for coupling the carrier to the support structure. The insulator has a first portion defining a first resistance for isolating the vibrations of the support structure during an application of a first force along a line of travel. The insulator also has a second portion defining a second resistance with the second resistance being greater than the first resistance for controlling the maxiumum displacement of the support structure after the application of the first force and during an application of a second force along the line of travel wherein the second force is greater than the first force. The insulator also provides for tunability of the nature and location of the transition between the first resistance and the second resistance.Type: GrantFiled: July 21, 2003Date of Patent: May 23, 2006Assignee: BASF CorporationInventor: Anand Huprikar
