Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, refer to Figure 1 to Figure 3 , the torque rod 1 according to the first embodiment of the present invention will be described. figure 1 is a plan view of the torque rod 1 . figure 2 is along figure 1 A cross-sectional view of the torque rod 1 on the line II-II. image 3 is along figure 1 Sectional view of the torque rod 1 on line III-III.

[0034] like figure 1 As shown, the torque rod 1 is an anti-vibration device for limiting the displacement of the engine in the roll direction (Roll direction) during acceleration by receiving torque from the engine. The torque rod 1 includes a first bush 10 mounted on the vehicle body side (not shown), a second bush 20 mounted on the engine side (not shown), and the first bush 10 and the second bush 20 The connection members 30 connected to each other. In addition, the first bush 10 may be attached to the eng...

Abstract

The present invention provides a torque rod capable of suppressing an outside member from being deformed or broken at the time of a vulcanized molding. A torque rod includes: a first anti-vibration device including: a cylindrical outside member having an axial end face, an axial inside member disposed on an internal peripheral side of the outside member, and an anti-vibration base body including arubber-like elastic body adhered, in a vulcanized manner, to an external peripheral face of the inside member and to an internal peripheral face of the outside member; and a connecting member connected to a second anti-vibration device connecting two members by a rubber-like elastic body, the connecting member being an article integrated with the outside member, wherein the outside member includes a level difference which is provided at the axial end face around an entire circumference and which has a radial outside axially concaved relative to a radial inside.

Description

technical field [0001] The invention relates to a torsion bar connected with two anti-vibration devices and its manufacturing method. Background technique [0002] Conventionally, a torque rod is known in which the inner peripheral surface of a cylindrical outer member and the outer peripheral surface of a shaft-shaped inner member are connected using a vibration-isolating base made of a rubber-like elastic body to form a first vibration-isolating device. The first anti-vibration device and the second anti-vibration device are connected radially to each other by a connecting member. In order to reduce the number of parts, there is a torque rod in which an outer member and a connecting member of the first vibration isolator are integrally formed (Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-210074 Contents of the invention [0006] (1) Technical problems to be solved [0007] ...
