Description
本発明は、車両のプロペラシャフト等の動力伝達軸に装着し当該動力伝達軸の振動を抑制するダンパ装置に関する。 The present invention relates to a damper device mounted on a power transmission shaft such as a propeller shaft of a vehicle to suppress vibration of the power transmission shaft.
自動車のドライブシャフトやプロペラシャフト等のシャフトには、当該シャフトが回転することに伴って生じる曲げ振動や捩り振動等の振動を抑制するため、シャフトの外周に取り付ける、一般にダイナミックダンパと呼ばれるダンパ装置が装着される。この種のダンパ装置は、シャフトを挿入する貫通孔が形成された装着部材と、略円筒形状の重錘である質量体とを有する。そして、装着部材と質量体とは、ゴム状弾性体にて構成される連結部材によって連結される（例えば、特許文献１参照）。 A damper device, generally called a dynamic damper, is mounted on the outer periphery of a shaft such as a drive shaft or propeller shaft of an automobile to suppress vibrations such as bending vibration and torsional vibration generated as the shaft rotates. It is attached. This type of damper device has a mounting member in which a through hole into which a shaft is inserted is formed, and a mass body which is a substantially cylindrical weight. And a mounting member and a mass are connected by the connection member comprised with a rubber-like elastic body (for example, refer patent document 1).
ダンパ装置全体の軸方向の長さを短く構成するため、特許文献１の図３に示すように、連結部材を、軸方向において略円筒形状の質量体よりも内側に配置する構成がある。特許文献１の図３では、質量体の軸方向の中央において、連結部材を配置し、質量体と装着部材とを連結している。 In order to shorten the axial length of the entire damper device, as shown in FIG. 3 of Patent Document 1, there is a configuration in which the connecting member is disposed inside the substantially cylindrical mass in the axial direction. In FIG. 3 of Patent Document 1, the connecting member is disposed at the axial center of the mass body, and the mass body and the mounting member are connected.
ところで、シャフトの振動低減のためにダンパ装置のイナーシャを大きくする場合、質量体を大きくすることが考えられる。ここで、シャフトの径方向にスペースが取れない場合、質量体の軸方向長さを長くすることが考えられる。 By the way, when enlarging the inertia of a damper apparatus for the vibration reduction of a shaft, it is possible to enlarge a mass body. Here, when space can not be taken in the radial direction of the shaft, it is conceivable to increase the axial length of the mass body.
しかしながら、特許文献１の図３の構成において、ダンパ装置のイナーシャを大きくするために質量体の軸方向長さを長くすると、質量体が車両の前後方向（プロペラシャフトの軸方向）に倒れるおそれがあった。 However, in the configuration of FIG. 3 of Patent Document 1, if the axial length of the mass is increased to increase the inertia of the damper device, the mass may fall in the longitudinal direction of the vehicle (axial direction of the propeller shaft). there were.
本発明は上述の点に鑑みてなされたものでありその目的は、ダンパ装置全体の軸方向長さを抑制しつつも質量体の軸方向の長さを長くした場合に質量体の倒れを防止し得るダンパ装置を提供することにある。 The present invention has been made in view of the above-described point, and an object thereof is to prevent the mass body from falling when the axial length of the mass body is increased while suppressing the axial length of the entire damper device. It is an object of the present invention to provide a damper device that can

In addition, the position which arrange | positions the damper apparatus D1 is not restricted to this, You may arrange | position in any position in the propeller shaft 1. FIG.
以下、ダンパ装置Ｄ１の詳細な構造を説明する。図２は、第一実施形態のダンパ装置Ｄ１を示す斜視図であり、（ａ）が軸方向の一方側から見た斜視図であり、（ｂ）が軸方向の他方側から見た斜視図である。図３は、第一実施形態のダンパ装置Ｄ１を軸方向から見た図であり、（ａ）が軸方向の一方側から見た図であり、（ｂ）が軸方向の他方側から見た図である。図４は、第一実施形態のダンパ装置Ｄ１の断面図であり、図３（ａ）におけるＡ−Ａ断面図である。 Hereinafter, the detailed structure of the damper device D1 will be described. FIG. 2 is a perspective view showing the damper device D1 of the first embodiment, wherein (a) is a perspective view seen from one side in the axial direction, and (b) is a perspective view seen from the other side in the axial direction It is. FIG. 3 is a view of the damper device D1 of the first embodiment viewed from the axial direction, (a) is a view viewed from one side in the axial direction, and (b) is viewed from the other side in the axial direction FIG. FIG. 4 is a cross-sectional view of the damper device D1 of the first embodiment, and is a cross-sectional view taken along the line A-A in FIG.
図２乃至図４に示すように、ダンパ装置Ｄ１は、プロペラシャフト１が挿入される貫通孔３５が形成され、プロペラシャフト１に装着される装着部材３０と、装着部材３０の径方向における外径方向に配置される質量体１０と、装着部材３０と質量体１０とを連結する連結部材２０とを備える。 As shown in FIGS. 2 to 4, the damper device D1 has a through hole 35 into which the propeller shaft 1 is inserted, and a mounting member 30 mounted on the propeller shaft 1 and an outer diameter of the mounting member 30 in the radial direction. A mass body 10 disposed in a direction and a connecting member 20 for connecting the mounting member 30 and the mass body 10 are provided.
質量体１０は、ダンパ装置Ｄ１における重錘であり、本実施形態では、断面が円環状の円筒形状に形成されている。質量体１０は、断面円環状の中心軸線がプロペラシャフト１の回転軸線と同一となるように配置される。具体的に、本実施形態では、第一シャフト１ａの回転軸線と質量体１０の中心軸線とが同一となる。 The mass body 10 is a weight in the damper device D1, and in the present embodiment, the mass body 10 is formed in a cylindrical shape having an annular cross section. The mass body 10 is disposed such that the central axis of the annular section is the same as the rotation axis of the propeller shaft 1. Specifically, in the present embodiment, the rotation axis of the first shaft 1a and the central axis of the mass body 10 are the same.
連結部材２０は、質量体１０の内周面１１から径方向内側に向かって設置される柱状の部材である。このため、本実施形態の連結部材２０は、質量体１０と装着部材３０との間を径方向に連結する。このように連結部材２０は、質量体１０の内周面１１から装着部材３０までを径方向に連結するため、連結部材２０の存在によってダンパ装置Ｄ１全体の軸方向長さが大型化することがない。また、連結部材２０は、ゴム等の弾性体から構成され、複数個且つ合計が偶数個の部材から構成される。 The connection member 20 is a columnar member installed radially inward from the inner circumferential surface 11 of the mass body 10. For this reason, the connecting member 20 of the present embodiment connects between the mass body 10 and the mounting member 30 in the radial direction. As described above, since the connecting member 20 radially connects the inner peripheral surface 11 of the mass body 10 to the mounting member 30 in the radial direction, the axial length of the entire damper device D1 can be increased by the presence of the connecting member 20. Absent. The connecting member 20 is formed of an elastic body such as rubber, and is formed of a plurality of members having an even number in total.
連結部材２０は、２種類の部材から構成される。具体的には、軸方向の一方側（図２の手前側、図３の手前側、及び図４の左側）に配置される第一連結部材２１と、軸方向の他方側（図２の奥側、図３の奥側、及び図４の右側）に配置される第二連結部材２２と、から構成される。第一連結部材２１と第二連結部材２２とは、質量体１０の内周面１１の周方向に沿って、質量体１０の内周面１１に交互に配置される。このため、質量体１０の周方向に沿って見ると、第一連結部材２１と第二連結部材２２とは、軸方向に互い違いになるように配置されることになる。 The connecting member 20 is composed of two types of members. Specifically, the first connecting member 21 disposed on one side in the axial direction (the front side of FIG. 2, the front side of FIG. 3, and the left side of FIG. 4) and the other side of the axial direction (the back of FIG. 2) And the second connecting member 22 disposed on the back side of FIG. 3 and the right side of FIG. 4). The first connecting members 21 and the second connecting members 22 are alternately arranged on the inner circumferential surface 11 of the mass body 10 along the circumferential direction of the inner circumferential surface 11 of the mass body 10. For this reason, when viewed along the circumferential direction of the mass body 10, the first connecting member 21 and the second connecting member 22 are arranged so as to be alternately staggered in the axial direction.
装着部材３０は、軸方向から見ると、中央に貫通孔３５が形成され、外周が円形状に形成される本体３０Ａを有する。本実施形態において、装着部材３０の軸方向の長さは、質量体１０の軸方向の長さと略同様の長さである。貫通孔３５は、本体３０Ａの中央において軸方向に貫通し、プロペラシャフト１が挿入される孔である。貫通孔３５に隣接する本体３０Ａには、円筒状の内面３６が形成され、この内面３６とプロペラシャフト１の外周とが嵌合することで、プロペラシャフト１が装着部材３０に対して装着される。 When viewed from the axial direction, the mounting member 30 has a main body 30A in which a through hole 35 is formed at the center and the outer periphery is formed in a circular shape. In the present embodiment, the axial length of the mounting member 30 is substantially the same as the axial length of the mass body 10. The through hole 35 is a hole which penetrates in the axial direction at the center of the main body 30A and into which the propeller shaft 1 is inserted. A cylindrical inner surface 36 is formed in the main body 30A adjacent to the through hole 35, and the propeller shaft 1 is mounted to the mounting member 30 by fitting the inner surface 36 to the outer periphery of the propeller shaft 1 .
装着部材３０の外周は、円形状に構成され、軸方向に延びるように構成されている。このため、装着部材３０の外周側面３１は、軸方向に延びる円柱状に構成される。 The outer periphery of the mounting member 30 is configured in a circular shape and configured to extend in the axial direction. Therefore, the outer peripheral side surface 31 of the mounting member 30 is formed in a cylindrical shape extending in the axial direction.
本実施形態の装着部材３０の外周側面３１には、３つの第一連結部材２１と３つの第二連結部材２２とが配置され、図２及び図３に示すように、第一連結部材２１と第二連結部材２２とが周方向に交互に並ぶように配置される。そして、隣接する第一連結部材２１と第二連結部材２２とは、周方向において６０°ごとに均等に配置される。 The three first connecting members 21 and the three second connecting members 22 are disposed on the outer peripheral side surface 31 of the mounting member 30 of the present embodiment, and as shown in FIGS. 2 and 3, the first connecting member 21 and It arrange | positions so that the 2nd connection member 22 may be alternately located in a line with the circumferential direction. And the 1st connection member 21 and the 2nd connection member 22 which adjoin are equally arrange | positioned every 60 degrees in the circumferential direction.
また、図２及び図４に示すように、第一連結部材２１は、軸方向において、質量体１０及び装着部材３０の一方側（図中左側）の端部に配置される。すなわち、第一連結部材２１は、軸方向における、質量体１０の一方側の端面である第一端面１２の近傍に配置される。第二連結部材２２は、軸方向において、質量体１０及び装着部材３０の他方側（図中右側）の端部に配置される。すなわち、第二連結部材２２は、軸方向における、質量体１０の他方側の端面である第二端面１３の近傍に配置される。 Further, as shown in FIG. 2 and FIG. 4, the first connection member 21 is disposed at an end of one side (left side in the drawing) of the mass body 10 and the mounting member 30 in the axial direction. That is, the first connection member 21 is disposed in the vicinity of the first end surface 12 which is an end surface on one side of the mass body 10 in the axial direction. The second connecting member 22 is disposed at the other end (right side in the drawing) of the mass body 10 and the mounting member 30 in the axial direction. That is, the second connection member 22 is disposed in the vicinity of the second end surface 13 which is the other end surface of the mass body 10 in the axial direction.
上述のように、第一連結部材２１及び第二連結部材２２を配置することで、装着部材３０の外周において、第一連結部材２１が、周方向に１２０°ごとに均等に設けられ、第二連結部材２２が、周方向に１２０°ごとに均等に設けられる。これにより、質量体１０の第一端面１２及び第二端面１３の倒れを防止する。すなわち、３つの第一連結部材２１が質量体１０の第一端面１２の中心位置（本実施形態では、軸方向一方側から見た質量体１０の重心位置）をずらさないように保持し、３つの第二連結部材２２が質量体１０の第二端面１３の中心位置（本実施形態では、軸方向他方側から見た質量体１０の重心位置）をずらさないように保持する。 As described above, by arranging the first connecting member 21 and the second connecting member 22, the first connecting members 21 are provided equally at every 120 ° in the circumferential direction on the outer periphery of the mounting member 30, The connecting members 22 are provided equally at every 120 ° in the circumferential direction. Thereby, the fall of the first end face 12 and the second end face 13 of the mass body 10 is prevented. That is, the three first connecting members 21 hold the center position of the first end face 12 of the mass body 10 (in the present embodiment, the center of gravity of the mass body 10 viewed from one side in the axial direction) The two second connecting members 22 hold the center position of the second end surface 13 of the mass body 10 (in the present embodiment, the center of gravity of the mass body 10 viewed from the other side in the axial direction) so as not to shift.
以上のように、本実施形態のダンパ装置Ｄ１においては、装着部材３０と質量体１０とを連結する連結部材２０を、軸方向の一方側に配置される複数の第一連結部材２１と、軸方向の他方側に配置される複数の第二連結部材２２と、から構成する。すると、質量体１０が軸方向の一方側に倒れた場合に、軸方向の一方側に配置された第一連結部材２１が質量体１０の倒れを防止することになり、質量体１０が軸方向の他方側に倒れた場合に、軸方向の他方側に配置された第二連結部材２２が質量体１０の倒れを防止することになる。また、第一連結部材２１と第二連結部材２２とは、質量体１０の周方向において交互に配置され、第一連結部材２１と第二連結部材２２とが周方向に隣接して配置されることとなるため、質量体１０の軸方向の一方側の倒れと質量体１０の軸方向の他方側の倒れとを効果的に防止することができる。よって、ダンパ装置Ｄ１全体の軸方向長さを抑制しつつも質量体１０の軸方向の長さを長くした場合に質量体１０の倒れを防止し得る。 As described above, in the damper device D1 of the present embodiment, the connecting member 20 for connecting the mounting member 30 and the mass body 10 is constituted by the plurality of first connecting members 21 arranged on one side in the axial direction, and the shaft And a plurality of second connecting members 22 disposed on the other side of the direction. Then, when the mass body 10 falls to one side in the axial direction, the first connection member 21 disposed on one side in the axial direction prevents the mass body 10 from falling, and the mass body 10 in the axial direction When the second connecting member 22 disposed on the other side in the axial direction prevents the mass body 10 from falling down. Moreover, the 1st connection member 21 and the 2nd connection member 22 are alternately arrange | positioned in the circumferential direction of the mass body 10, and the 1st connection member 21 and the 2nd connection member 22 are adjacently arranged in the circumferential direction. As a result, it is possible to effectively prevent the one side of the axial direction of the mass body 10 from falling and the other side of the axial direction of the mass body 10 from falling. Therefore, the fall of the mass body 10 can be prevented when the axial length of the mass body 10 is increased while suppressing the axial length of the entire damper device D1.
また、本実施形態では、第一連結部材２１と第二連結部材２２とを周方向において均等に配置することで、連結部材２０（第一連結部材２１及び第二連結部材２２）が、周方向において均一に質量体１０の倒れを防止することとなるため、より効果的に質量体１０の倒れを防止することができる。 Further, in the present embodiment, by evenly arranging the first connection member 21 and the second connection member 22 in the circumferential direction, the connection member 20 (the first connection member 21 and the second connection member 22) is circumferentially separated. In the above, it is possible to prevent the falling of the mass body 10 uniformly, so that the falling of the mass body 10 can be prevented more effectively.
すなわち、３つの第一連結部材２１と３つの第二連結部材２２のそれぞれを周方向に均等に配置する。すると、周方向に１２０°ごとに均等に配置された３つの第一連結部材２１は、軸方向の一方側において質量体１０を均等に支持することとなるため、質量体１０の一方側において質量体１０の重心がずれることを抑制する。また、周方向に１２０°ごとに均等に配置された３つの第二連結部材２２は、軸方向の他方側において質量体１０を均等に支持することとなるため、質量体１０の他方側において質量体１０の重心がずれることを抑制する。すると、質量体１０の軸方向における一方及び他方がいずれも安定して支持されることで、より効果的に質量体１０の倒れを防止することができる。 That is, each of the three first connection members 21 and the three second connection members 22 is equally disposed in the circumferential direction. Then, since the three first connection members 21 evenly arranged at every 120 ° in the circumferential direction support the mass body 10 uniformly on one side in the axial direction, the mass on one side of the mass body 10 is obtained. It suppresses that the center of gravity of the body 10 shifts. In addition, since the three second connection members 22 evenly arranged at every 120 ° in the circumferential direction support the mass body 10 equally on the other side in the axial direction, the mass on the other side of the mass body 10 It suppresses that the center of gravity of the body 10 shifts. Then, since one and the other in the axial direction of the mass 10 are stably supported, it is possible to more effectively prevent the mass 10 from falling down.

次に、本発明の第二実施形態について説明する。なお、第二実施形態の説明及び対応する図面においては、前述の実施形態と同一又は相当する構成部分には同一符号を付し、以下ではその部分の詳細な説明を省略する。また、以下で説明する事項以外の事項については、前述の実施形態と同様である。
Second Embodiment
Next, a second embodiment of the present invention will be described. In the description of the second embodiment and the corresponding drawings, the same or corresponding components as or to those of the above-described embodiment are designated by the same reference numerals, and the detailed description of such components will be omitted hereinafter. Further, matters other than the matters described below are the same as those of the above-described embodiment.
以下、第二実施形態のダンパ装置Ｄ２の詳細な構造を説明する。図５は、本発明の第二実施形態のダンパ装置Ｄ２を軸方向から見た図であり、（ａ）が軸方向の一方側から見た図であり、（ｂ）が軸方向の他方側から見た図である。 Hereinafter, the detailed structure of the damper device D2 of the second embodiment will be described. FIG. 5 is a view of a damper device D2 according to a second embodiment of the present invention as viewed from the axial direction, where (a) is a view as viewed from one side in the axial direction, and (b) is the other side in the axial direction It is the figure seen from.
図５に示すように、ダンパ装置Ｄ２は、質量体１０と、連結部材２０と、装着部材３０とを備える。第二実施形態においては、前述の実施形態とは連結部材２０の数と配置が異なるため、次に、連結部材２０の詳細構成を説明する。 As shown in FIG. 5, the damper device D2 includes a mass body 10, a connecting member 20, and a mounting member 30. In the second embodiment, since the number and the arrangement of the connecting members 20 are different from those in the above-described embodiment, the detailed configuration of the connecting members 20 will be described next.
本実施形態の装着部材３０の外周側面３１には、連結部材２０として、４つの第一連結部材２１と４つの第二連結部材２２とが配置される。そして、第一連結部材２１と第二連結部材２２とは、周方向に交互に並ぶように配置される。また、隣接する第一連結部材２１と第二連結部材２２とは、周方向において４５°ごとに均等に配置される。 The four first connection members 21 and the four second connection members 22 are disposed as the connection members 20 on the outer peripheral side surface 31 of the mounting member 30 according to the present embodiment. The first connecting members 21 and the second connecting members 22 are arranged alternately in the circumferential direction. Moreover, the adjacent 1st connection member 21 and the 2nd connection member 22 are equally arrange | positioned every 45 degrees in the circumferential direction.
上述のように、第一連結部材２１及び第二連結部材２２を配置することで、装着部材３０の外周において、４つの第一連結部材２１が、周方向に９０°ごとに均等に設けられ、４つの第二連結部材２２が、周方向に９０°ごとに均等に設けられる。これにより、質量体１０の第一端面１２及び第二端面１３の倒れを防止する。すなわち、４つの第一連結部材２１が質量体１０の第一端面１２の中心位置（本実施形態では、軸方向一方側から見た質量体１０の重心位置）をずらさないように保持し、４つの第二連結部材２２が質量体１０の第二端面１３の中心位置（本実施形態では、軸方向他方側から見た質量体１０の重心位置）をずらさないように保持する。 As described above, by arranging the first connecting member 21 and the second connecting member 22, the four first connecting members 21 are provided equally at every 90 ° in the circumferential direction on the outer periphery of the mounting member 30, Four second connection members 22 are provided equally at every 90 ° in the circumferential direction. Thereby, the fall of the first end face 12 and the second end face 13 of the mass body 10 is prevented. That is, the four first connecting members 21 hold the center position of the first end face 12 of the mass body 10 (in the present embodiment, the center of gravity of the mass body 10 viewed from one side in the axial direction) The two second connecting members 22 hold the center position of the second end surface 13 of the mass body 10 (in the present embodiment, the center of gravity of the mass body 10 viewed from the other side in the axial direction) so as not to shift.
以上のように、本実施形態のダンパ装置Ｄ２においては、４つの第一連結部材２１と４つの第二連結部材２２のそれぞれを周方向に均等に配置する。すると、周方向に９０°ごとに均等に配置された４つの第一連結部材２１は、軸方向の一方側において質量体１０を均等に支持することとなるため、質量体１０の一方側において質量体１０の重心がずれることを抑制する。また、周方向に９０°ごとに均等に配置された４つの第二連結部材２２は、軸方向の他方側において質量体１０を均等に支持することとなるため、質量体１０の他方側において質量体１０の重心がずれることを抑制する。すると、質量体１０の軸方向における一方及び他方がいずれも安定して支持されることで、より効果的に質量体１０の倒れを防止することができる。 As described above, in the damper device D2 of the present embodiment, the four first connection members 21 and the four second connection members 22 are uniformly arranged in the circumferential direction. Then, since the four first connection members 21 uniformly disposed at every 90 ° in the circumferential direction support the mass body 10 uniformly on one side in the axial direction, the mass on one side of the mass body 10 is obtained. It suppresses that the center of gravity of the body 10 shifts. In addition, since the four second connection members 22 evenly arranged at every 90 ° in the circumferential direction support the mass body 10 equally on the other side in the axial direction, the mass on the other side of the mass body 10 It suppresses that the center of gravity of the body 10 shifts. Then, since one and the other in the axial direction of the mass 10 are stably supported, it is possible to more effectively prevent the mass 10 from falling down.
