Description
Technical field
The present invention relates to a kind of vibration reducing sleeve in the hole of being pressed into that is pressed into the mounting object parts, its by inner core, urceolus, between inner/outer tube and the rubber-like elastic body that links aforementioned inner core and urceolus constitute, on the position that clips aforementioned inner core of aforementioned rubber-like elastic body, be formed with pair of holes.
Background technique
This vibration reducing sleeve is pressed into being pressed in the hole of arm (being equivalent to the mounting object parts) of the suspension of supporting automotive wheel, and is fixed on by the fixing bolt that has penetrated inner core on the member of vehicle body side.Under this stationary state, the pair of holes that is formed on the aforementioned rubber body for example is arranged on the fore-and-aft direction of car body.Thus, reduced the spring constant of fore-and-aft direction, the comfortable feel of taking is improved, increased the spring constant of the left and right directions of car body simultaneously, the stability of manipulation is improved.
Under the situation of above-mentioned structure,, set the spring constant of fore-and-aft direction for desired value with regard to being difficult to if become the state of the orientation in hole with respect to the fore-and-aft direction inclination of car body.Therefore, vibration reducing sleeve must be pressed at this and be pressed into to accurate positioning being pressed in the hole of arm on circumferencial direction in hole.Above-mentioned example is orientation and the corresponding to example of car body fore-and-aft direction that makes the hole, but the orientation that makes the hole structure along the direction outside the fore-and-aft direction of car body is also arranged.In such structure, vibration reducing sleeve also must be pressed at this and be pressed into to accurate positioning being pressed in the hole of arm on circumferencial direction in hole.
With vibration reducing sleeve under the situation that being pressed into of arm is pressed in the hole, an end of vibration reducing sleeve is embedded in the bearing hole of the supporting fixture that is pressed into usefulness, supporting fixture is from an end of downside fixed bearing urceolus.Then, the upside of arm from another end of vibration reducing sleeve on the holding part that remains on press-in device descended, arm is pressed into and is embedded on the vibration reducing sleeve outward.Thus, vibration reducing sleeve is pressed into and is embedded in being pressed in the hole of arm.The position relation of the holding part of supporting fixture and press-in device is accurately set, so as long as on the circumferencial direction of bearing hole, exactly vibration reducing sleeve is configured in the bearing hole of supporting fixture, just can with the vibration reducing sleeve accurate positioning be pressed into being pressed in the hole of arm.
In the past, with respect to the bearing hole of supporting fixture under situation about on the aforementioned circumferencial direction vibration reducing sleeve being positioned, what the operator adopted is following method: make the regulation position (for example, the center of hole on the circumferencial direction of inner/outer tube) in hole involutory with the reference point location that is formed on the supporting fixture.
According to above-mentioned method in the past, the operator makes the regulation position in hole involutory with the reference point location that is formed on the supporting fixture, so cause vibration reducing sleeve inaccurate with respect to the location of the bearing hole of supporting fixture sometimes.
Summary of the invention
The objective of the invention is to, provide a kind of can carry out exactly with respect to supporting fixture the location, be pressed into to dislocation-free the vibration reducing sleeve in the hole of being pressed into of mounting object parts in a circumferential direction.
The present invention is a kind of vibration reducing sleeve, be pressed into being pressed in the hole of mounting object parts, by inner core, urceolus, and between inner/outer tube and the rubber-like elastic body that links aforementioned inner core and urceolus constitute, on the position that clips aforementioned inner core of aforementioned rubber-like elastic body, be formed with pair of holes, it is characterized in that, constitute, aforementioned inner/outer tube axially on the 1st rubber-like elasticity body portion of end one side, and/or on the 2nd rubber-like elasticity body portion of another end one side on the aforementioned axial, be provided with the rubber protuberance that projects upwards in aforementioned axis more than 1 or 2, aforementioned rubber convex portion more than 1 or 2 is entrenched in respectively in the positioning hole more than 1 or 2 that is formed on the supporting fixture that is pressed into usefulness, and the described supporting fixture that is pressed into usefulness carries out fixed bearing to an end or another end of aforementioned urceolus.
According to such formation, with vibration reducing sleeve under the situation that being pressed into of mounting object parts is pressed in the hole, can be as being pushed down into.That is, make the supporting fixture that is pressed into usefulness carry out fixed bearing from an end or another end in the axial direction to urceolus.At this moment, the rubber protuberance more than 1 or 2 of the 1st rubber-like elasticity body portion side, perhaps the rubber convex portion more than 1 or 2 of the 2nd rubber-like elasticity body portion side is entrenched in respectively in 1 of supporting fixture or 2 positioning holes.Thus, just vibration reducing sleeve accurately can be located on the circumferencial direction of inner/outer tube with respect to supporting fixture.Under this bearing state, vibration reducing sleeve is pressed into being pressed in the hole of mounting object parts.
In the present invention, if aforementioned rubber protuberance and aforementioned the 1st rubber-like elasticity body portion and the 2nd rubber-like elasticity body portion sulfidization molding integratedly more than 1 or 2 just can be so that be difficult to that the rubber protuberance is stated the 1st rubber-like elasticity body portion and the 2nd rubber-like elasticity body portion is separated in the past.
In the present invention, if aforementioned inner core is set for than outer tube length, the two end part of aforementioned inner core are more outstanding to the axial outside than the two end part of aforementioned urceolus respectively, aforementioned rubber protuberance more than 1 or 2 is more outstanding to the axial outside than an end or another end of aforementioned urceolus, as long as then have a look at vibration reducing sleeve, just can determine the rubber protuberance.And on one side can observe the rubber protuberance, Yi Bian the rubber protuberance is entrenched in the positioning hole of supporting fixture side, vibration reducing sleeve is simplified with respect to the positioning operation of supporting fixture.
In the present invention, if the sulfuration of rubber protuberance is bonded on the outer circumferential face of inner core, then the rubber protuberance is supported by inner core, so can improve the shape keeping of rubber protuberance.Its result is easy to the rubber convex portion more than 1 or 2 is entrenched in respectively in the positioning hole more than 1 or 2 of supporting fixture.
In the present invention, can constitute, aforementioned rubber protuberance more than 1 or 2 with the arranged spaced of equalization on the circumferencial direction of aforementioned inner/outer tube.
According to the present invention, the location that can carry out exactly with respect to supporting fixture can be provided, be pressed into to dislocation-free the vibration reducing sleeve in the hole of being pressed into of mounting object parts in a circumferential direction.
