Patent number: 9322450Abstract: A torque rod having an arm portion, a ring portion formed on each end of the arm portion in a longitudinal direction of the arm portion, and a rubber bushing that is integrally provided with the ring portion. The arm portion is formed from a material that is lower in specific gravity than iron. A weight is provided in a potion of the rubber bushing other than a principal spring portion. The principle spring portion, which absorbs principle vibration to be isolated, is formed by an elastic arm portion that extends radially outwardly from an inner cylinder located substantially in a center of the rubber bushing and is connected to the ring portion. An aperture, which is a separation space, is provided between the elastic arm portion and the ring portion.Type: GrantFiled: March 3, 2014Date of Patent: April 26, 2016Assignees: YAMASHITA RUBBER KABUSHIKI KAISHA, HONDA MOTOR CO., LTD.Inventors: Hironao Nishimae, Nobuo Kubo, Hiroshi Yanagase

Patent number: 8167286Abstract: A cylindrical vibration isolating device having an inner cylinder, an outer cylinder surrounding the inner cylinder, an elastic leg having a pair of right and left leg portions to connect the inner cylinder and the outer cylinder and, when viewed in the axial direction of the inner cylinder, being formed in a substantially inverted V-shape while placing the inner cylinder in an intermediate position, and a mass projection being provided in the elastic leg such that the mass projection resonates in a frequency range that the elastic leg causes bending resonance. The mass projection is provided outside of an inner restraint line that is a perpendicular line passing an outermost point of an inner restrained portion that is a connected portion between the inner cylinder and the elastic leg.Type: GrantFiled: April 16, 2008Date of Patent: May 1, 2012Assignee: Yamashita Rubber Kabushiki KaishaInventors: Yukinobu Hirano, Hironao Nishimae
