Specific embodiment
Hereinafter, referring to Fig.1 and Fig. 2, carrying out overall description to torque rod 1.The tool of torque rod 1 involved in present embodiment
There are the first outer cylindrical portion 10, the second outer cylindrical portion 11 and the linking part 20 for linking the first outer cylindrical portion 10 and the second outer cylindrical portion 11.?
It is configured with shaft component 30 in first in the cylinder of one outer cylindrical portion 10, shaft component in second is configured in the cylinder of the second outer cylindrical portion 11
31.Shaft component 30 and the first outer cylindrical portion 10 are linked by 40 elasticity of the first rubber elastomer in first, shaft component 31 and the in second
Two outer cylindrical portions 11 are linked by 41 elasticity of the second rubber elastomer.Wherein, the first outer cylindrical portion 10, the second outer cylindrical portion 11 and linking part
20 are formed from a resin, and shaft component 31 is each made of a metal in shaft component 30, second in first, such as made of aluminum.
In addition, the inner surface of the first outer cylindrical portion 10 is covered by the covering rubber 80 being integrally formed with the first rubber elastomer 40
Lid, also, aftermentioned first retainer 60, the second retainer 70 also with first rubber elastomer 40 and the covering rubber 80 1
Body is formed.
When further explanation, the first rubber elastomer 40 is made of a pair of of elastomer, and a pair of elastomer phase is for connection
The central axis A in portion 20 is symmetrical, and is respectively configured as the side far from the second outer cylindrical portion 11 relative to central axis A in sharp
Overturning angle.On the direction of the central axis A of linking part 20, between the first retainer 60 relative to shaft component 30 in first to separate
Every mode configure the inner surface (such as in figure right side) far from the second outer cylindrical portion 11 in the first outer cylindrical portion 10.In linking part
On the direction of 20 central axis A, the second retainer 70 is in a manner of relative to the inner surface interval of the first outer cylindrical portion 10
Configure the end face (such as left side in figure) close to the second outer cylindrical portion 11 in first in shaft component 30.
In addition, in shaft component 30 being plane with the link surface of the first rubber elastomer 40 connection in first, thus make the
Shaft component 30 becomes easy processing in one, can effectively improve processing efficiency and reduce cost.In contrast, outside first
The position linked with the first rubber elastomer 40 in canister portion 10 is formed with towards 30 side of shaft component protrusion outstanding in first, is led to
It crosses and the protrusion is set, the elastic characteristic of rubber elastomer can be tuned.
Hereinafter, the protrusion is described in detail.
[first embodiment]
Referring to Fig.1, at the central axis A relative to linking part 20 in the first outer cylindrical portion 10 symmetrical upper and lower two, shape
At having towards 30 side of shaft component protrusion 50 outstanding in first.The protrusion 50 be formed in the first outer cylindrical portion 10 with the first rubber
The position that elastomer 40 links, and it is embedded in first rubber elastomer 40.
Wherein, the top surface of the protrusion 50 is plane.By the way that the top surface of protrusion 50 is set as plane, increase the protrusion 50 with
Along radial direction with the distance between the end face of shaft component 30 in the protrusion 50 corresponding first, it is thereby advantageously ensured that first
The elasticity of rubber elastomer 40.
[second embodiment]
Referring to Fig. 2, at the central axis A relative to linking part 20 symmetrical upper and lower two in the first outer cylindrical portion 10, shape
At having towards 30 side of shaft component protrusion 51 outstanding in first.The protrusion 51 be formed in the first outer cylindrical portion 10 with the first rubber
The position that elastomer 40 links, and it is embedded in first rubber elastomer 40.
Wherein, which has three-dimension curved surface shape.By the way that protrusion 51 is set as three-dimension curved surface shape, first is increased
The thickness of the linking part linked with the first rubber elastomer 40 in the radial direction in outer cylindrical portion 10, it is thereby advantageously ensured that
The durability of first outer cylindrical portion 10.
By being compared to first embodiment and second embodiment it is found that when the top surface of protrusion is set as plane,
It can effectively ensure that the elasticity of the first elastomer 40, but compared with the case where protrusion is three-dimension curved surface shape, the first outer cylindrical portion
10 durability reduces.On the contrary, can effectively ensure that the resistance to of the first outer cylindrical portion 10 when protrusion is set as three-dimension curved surface shape
Long property, but compared with the case where top surface of protrusion is plane, the elasticity of the first elastomer 40 reduces.Those skilled in the art can
Select the shape of protrusion according to actual needs.
It should be noted that the present invention is not limited to the above embodiments and embodiment, right can not departed from
It makes various changes, improve in the case where the purport and range of the utility model defined by claim.
