Patent number: 9709116Abstract: A large ring part of a torque rod includes an outer frame section, an inner member, an intermediate ring and an elastic vibration isolating main body. The outer frame section and the intermediate ring are integrally combined with the elastic vibration isolating main body. An inner clearance is provided between the intermediate ring and the inner member such as to surround the circumference of the inner member. The intermediate ring is movable relative to the inner member in the axial direction. With respect to the vibration in the direction of a mounting shaft, the outer frame section, the intermediate ring and the elastic vibration isolating main body move together in the axial direction in relation to the inner member, whereby the spring in the direction of the mounting shaft is weakened and the resonance frequency of the rigid body resonance in the direction of the mounting shaft is decreased.Type: GrantFiled: August 23, 2013Date of Patent: July 18, 2017Assignee: YAMASHITA RUBBER KABUSHIKI KAISHAInventor: Hitoshi Shimada

Patent number: 9470289Abstract: A torque rod includes a rod main body, a first bushing and a second bushing. The rod main body is made of resin and provided integral with a first ring section and a second ring section on each end of an arm section. A first rib extends from the arm section to a front lateral surface of the second ring section. In a plan view, a second rib is provided to overlap with the first rib. The first rib projects forwardly of and in the left and right directions of the second rib. This projecting portion forms an enlarged diameter portion. Due to this enlarged diameter portion, an area of the first rib is made larger than an area of the second rib thereby to increase a rigidity of a forward side of the second ring.Type: GrantFiled: August 10, 2013Date of Patent: October 18, 2016Assignee: YAMASHITA RUBBER KABUSHIKI KAISHAInventor: Hitoshi Shimada
