Patent number: 10280826Abstract: Provided is an insulator which is capable of reducing an abnormal noise. A first mounting hole engaging a vehicle body side is formed in a first portion, and a second mounting hole engaging an exhaust pipe side is formed in a second portion disposed to be spaced apart from the first portion. The first section and the second portion are coupled to each other by the coupling portion. The first portion and the second portion are adapted such that at least the inner peripheral surfaces of the first mounting hole and the second mounting hole are configured from a rubber-like elastic body having a self-lubrication property.Type: GrantFiled: June 9, 2015Date of Patent: May 7, 2019Assignee: TOYO TIRE CORPORATIONInventor: Tomoyoshi Edo

Publication number: 20180291782Abstract: An insulator includes a first portion, a second portion, a pair of coupling portions, a first stopper surface and a second stopper surface, and a plurality of protrusions. The second portion is arranged underneath the first portion across a predetermined virtual axis. The pair of the coupling portions couple the first portion to the second portion. The pair of the coupling portions are separately arranged on both sides in an axis-perpendicular direction of the virtual axis. The first stopper surface and the second stopper surface are famed on the first portion and the second portion, respectively, between the pair of the coupling portions with intervals to the coupling portions. The plurality of the protrusions project from at least one of the first stopper surface and the second stopper surface. The plurality of the protrusions are arranged in an axial direction and the axis-perpendicular direction of the virtual axis.Type: ApplicationFiled: February 15, 2018Publication date: October 11, 2018Applicant: TOYO TIRE & RUBBER CO., LTD.Inventor: Tomoyoshi Edo

Patent number: 9523407Abstract: An anti-vibration unit, which enables a reduction in man-hours to be achieved during manufacturing and a reduction in the number of parts, is provided. A boss member of an anti-vibration device is pressed into a press-fitting section of a second bracket so as to be firmly fixed. The omission of the bolt enables a corresponding reduction in the number of parts. Moreover, by omitting the bolt in this way, there is no need to form a female threaded section on the boss member of the anti-vibration device, thus enabling a corresponding reduction in man-hours during manufacturing. In addition, when chemically treating the boss member of the anti-vibration device, it is unnecessary to implement a step for protecting the female threaded section with a masking bolt, thus eliminating the need to attach and detach the masking bolt, which in turn enables a corresponding reduction in man-hours during manufacturing.Type: GrantFiled: May 31, 2012Date of Patent: December 20, 2016Assignee: TOYO TIRE & RUBBER CO., LTD.Inventors: Tatsuya Oniwa, Tomoyoshi Edo, Kenichi Koshikawa, Hironori Kato

Patent number: 9403430Abstract: To provide an insulator that can reduce an abnormal noise made when stopper surfaces abut and separate. A first mounting hole engaging a vehicle body side is formed in a first portion. A second mounting hole is formed in a second portion and arranged separately from the first portion. The first portion and the second portion form a first stopper surface and a second stopper surface, respectively. At least one of the first stopper surface and the second stopper surface opposite to one another is formed in a curved surface shape as a part of a cylindrical side surface. The first stopper surface and the second stopper surface can have a non-linear property when abutting and separating. Accordingly, an abnormal noise made when abutting and separating can be reduced.Type: GrantFiled: July 16, 2015Date of Patent: August 2, 2016Assignee: TOYO TIRE & RUBBER CO., LTD.Inventor: Tomoyoshi Edo

Patent number: 7464918Abstract: Provided is a liquid sealing type vibration control device capable of sufficiently reducing strange sounds which comprises a first attachment fitting (1), a second attachment fitting (2), a vibration-isolating base body (3), a diaphragm (9), a partition body (12), and an orifice (25), the partition body (12) including an elastic partition membrane (15) and a pair of lattice members (17, 18). The elastic partition membrane (15) is provided on its both faces with rib groups (50) in a projecting manner, the rib groups (50) each consist of plural first ribs (51) and plural second ribs (52) mingled mutually, the first ribs (51) are set in such a height dimension that their tops can be situated apart from the lattice members (17, 18), and the second ribs (52) are set in such a height dimension that their tops abut on the lattice members (17, 18) and in a smaller rib width than the first ribs (51).Type: GrantFiled: January 9, 2004Date of Patent: December 16, 2008Assignee: Toyo Tire & Rubber Co., Ltd.Inventors: Shingo Hatakeyama, Masaaki Ito, Tomoyoshi Edo
