Description

本出願において開示された技術は、ダンパ装置に関する。 The technology disclosed in this application relates to a damper device.

車両等において、エンジン等の駆動源と変速機との間のトルク伝達経路上には、当該駆動源から当該変速機に向けて伝達されるトルクの振動を吸収するダンパ装置が設けられており、ダンパ装置は例えばクラッチ装置に組み込まれている。 In a vehicle or the like, a damper device is provided on a torque transmission path between a drive source such as an engine and a transmission to absorb vibration of torque transmitted from the drive source toward the transmission. The damper device is incorporated in, for example, a clutch device.

ダンパ装置の一般的な構成としては、互いに相対回転可能な入力部材としての第１回転体（例えば、ディスクプレート）と出力部材としての第２回転体（例えばハブ）との間に、コイルスプリングを介在させて、コイルスプリングの弾性変形を利用してトルクの変動に起因する捩り方向の振動を吸収して減衰させる技術が知られている。 As a general configuration of a damper device, a coil spring is provided between a first rotating body (for example, a disk plate) as an input member that can rotate relative to each other and a second rotating body (for example, a hub) as an output member. There is known a technique of absorbing and damping the vibration in the torsional direction caused by the fluctuation of torque by interposing it and utilizing the elastic deformation of the coil spring.

具体的なダンパ装置の構成として、例えば特許文献１には、第１ダンパ部と、当該第１ダンパ部よりも径方向内側に配される第２ダンパ部と、を有するダンパ装置が開示されている。 As a specific configuration of the damper device, for example, Patent Document 1 discloses a damper device having a first damper portion and a second damper portion arranged radially inside the first damper portion. There is.

また、特許文献２には、メインダンパ部と、当該メインダンパ部よりも径方向内側に配されるプリダンパ部とを備え、当該プリダンパ部の各窓孔には円周方向に２つのコイルスプリングが直列に収容されるダンパ装置が開示されている。 Further, Patent Document 2 includes a main damper portion and a pre-damper portion arranged radially inside the main damper portion, and each window hole of the pre-damper portion has two coil springs in the circumferential direction. Damper devices housed in series are disclosed.

特許第５３７６０６１号明細書Japanese Patent No. 5376061 国際公開第２０１１／０６２１５８号International Publication No. 2011/062158

特許文献２に記載のダンパ装置においては、メインダンパ部に対してプリダンパ部を軸方向にずらした位置に配置した上で、当該プリダンパ部における２つのコイルスプリングを支持するために、当該コイルスプリングの径方向外側（コイルスプリングを収容する収容部を形成するドリブンプレートの径方向外側）に環状部材を別途設け、当該環状部材から径方向内側に突出する支持部を設ける構成が採用されている。しかしながら、このような構成が採用される結果、特許文献２に記載のダンパ装置においては、ダンパ装置全体として軸方向の体格が大きくなってしまい、且つプリダンパ部におけるコイルスプリングを支持する環状部材を径方向外側に別途設ける必要があるため、径方向においてコイルスプリングを配置する場所に制約がある。 In the damper device described in Patent Document 2, the pre-damper portion is arranged at a position shifted in the axial direction with respect to the main damper portion, and then the coil spring is supported in order to support the two coil springs in the pre-damper portion. An annular member is separately provided on the radial outer side (the radial outer side of the driven plate forming the accommodating portion for accommodating the coil spring), and a support portion protruding inward in the radial direction from the annular member is provided. However, as a result of adopting such a configuration, in the damper device described in Patent Document 2, the physique of the damper device as a whole in the axial direction becomes large, and the diameter of the annular member that supports the coil spring in the pre-damper portion is increased. Since it is necessary to separately provide it on the outside in the direction, there is a restriction on the place where the coil spring is arranged in the radial direction.

そこで、様々な実施形態により、全体としてコンパクトな体格であり、且つ設計自由度が高いダンパ装置を提供する。 Therefore, various embodiments are provided to provide a damper device having a compact physique as a whole and a high degree of freedom in design.

一態様に係るダンパ装置は、回転軸周りに回転する第１回転体と、前記回転軸周りに前記第１回転体に対し相対回転する第２回転体と、前記回転軸周りに前記第１回転体及び前記第２回転体に対し相対回転する第３回転体と、前記第１回転体と前記第２回転体とを回転方向に弾性連結させる第１弾性機構部と、少なくとも２つの弾性体、及び２つの前記弾性体の間に配置され２つの前記弾性体を支持する少なくとも１つのシート部材を含み、前記第２回転体と前記第３回転体とを回転方向に弾性連結させ、前記第１弾性機構部よりも径方向内側に配される第２弾性機構部と、前記軸方向において前記第３回転体に隣接して配置される環状の本体部、及び前記本体部から軸方向に延び前記シート部材を径方向外側から支持する支持部を有し、前記第３回転体と一体的に回転する中間部材と、を具備するものである。 The damper device according to one embodiment includes a first rotating body that rotates around a rotation axis, a second rotating body that rotates relative to the first rotating body around the rotation axis, and the first rotation around the rotation axis. A third rotating body that rotates relative to the body and the second rotating body, a first elastic mechanism portion that elastically connects the first rotating body and the second rotating body in the rotational direction, and at least two elastic bodies. And at least one sheet member arranged between the two elastic bodies and supporting the two elastic bodies, the second rotating body and the third rotating body are elastically connected in the rotational direction, and the first The second elastic mechanism portion arranged radially inside the elastic mechanism portion, the annular main body portion arranged adjacent to the third rotating body in the axial direction, and the axially extending from the main body portion. It has a support portion that supports the seat member from the outside in the radial direction, and includes an intermediate member that rotates integrally with the third rotating body.

この構成によれば、ダンパ装置は、第２弾性機構部において、２つの弾性体を直列に収容しつつ、全体の体格をコンパクトにしつつ２つの弾性体を支持することが可能となる。また、中間部材の本体部は、軸方向において第３回転体に隣接して配置されるため、径方向における第２弾性機構部の配置場所について設計自由度が向上する。 According to this configuration, the damper device can support the two elastic bodies in the second elastic mechanism portion while accommodating the two elastic bodies in series and making the overall physique compact. Further, since the main body portion of the intermediate member is arranged adjacent to the third rotating body in the axial direction, the degree of freedom in designing the arrangement location of the second elastic mechanism portion in the radial direction is improved.

また、一態様に係る前記ダンパ装置において、前記第２弾性機構部は、前記径方向において、前記第２回転体と前記第３回転体との間に配置されることが好ましい。 Further, in the damper device according to one aspect, it is preferable that the second elastic mechanism portion is arranged between the second rotating body and the third rotating body in the radial direction.

この構成とすることによって、軸方向において体格がコンパクトなダンパ装置を提供することが可能となる。 With this configuration, it is possible to provide a damper device having a compact physique in the axial direction.

また、一態様に係る前記ダンパ装置において、前記シート部材は、前記中間部材の前記支持部に対向する凹部を有し、前記支持部は、前記凹部に対応する凸部であることが好ましい。 Further, in the damper device according to one aspect, it is preferable that the seat member has a concave portion facing the support portion of the intermediate member, and the support portion is a convex portion corresponding to the concave portion.

この構成とすることによって、シート部材は支持部によって効率的に支持されるため、シート部材の径方向への移動が規制される。同様に、シート部材によって支持される２つの弾性体の径方向への移動も規制される。 With this configuration, the seat member is efficiently supported by the support portion, so that the movement of the seat member in the radial direction is restricted. Similarly, the radial movement of the two elastic bodies supported by the seat member is also restricted.

様々な実施形態によれば、全体としてコンパクトな体格のダンパ装置を提供することができる。 According to various embodiments, it is possible to provide a damper device having a compact physique as a whole.

A gap G (not shown) for receiving the engaging portion 208d 2 on the fourth other end side is similarly formed between the fourth other end surface 104d 2 formed by the two disc plate 100B. These structures are similarly formed in regions I to III.

１−２．外ハブ２００
外ハブ２００は、例えば、金属材料により形成され、全体として略環状に延びる形状を有し、第１ディスクプレート１００Ａ及び第２ディスクプレート１００Ｂに挟まれて、回転軸Ｏの周りにディスクプレート１００（第１ディスクプレート１００Ａ及び第２ディスクプレート１００Ｂ）に対して相対回転可能に設けられる。また、外ハブ２００は、図１、図２、及び図４に示すように、径方向外側に延びるフランジ２０６と、少なくとも後述する内ハブ３００、第２弾性機構部５００、及び中間部材６００を収容する環孔２０１が設けられる。 1-2. Outer hub 200
The outer hub 200 is formed of, for example, a metal material, has a shape extending substantially annularly as a whole, is sandwiched between the first disc plate 100A and the second disc plate 100B, and is sandwiched between the first disc plate 100A and the second disc plate 100B, and the disc plate 100 ( It is provided so as to be rotatable relative to the first disc plate 100A and the second disc plate 100B). Further, as shown in FIGS. 1, 2, and 4, the outer hub 200 accommodates a flange 206 extending radially outward, and at least an inner hub 300, a second elastic mechanism portion 500, and an intermediate member 600, which will be described later. The ring hole 201 is provided.

フランジ２０６には、図１、図２、及び図４に示すように、その外周において周方向に沿って少なくとも１つの切欠きが形成される。一実施形態では、一例として、フランジ２０６には、その外周において周方向に沿って等間隔（周方向において９０度の間隔）で４つの切欠き２０６ａ、２０６ｂ、２０６ｃ、及び２０６ｄが形成される。図１に示すように、概念的に、ダンパ装置１を上面からみて、各々が扇形を有する４つの領域Ｉ、ＩＩ、ＩＩＩ、ＩＶに分けて考えると、フランジ２０６には、領域Ｉ〜ＩＶに対応付けて、それぞれ、第１切欠き２０６ａ、第２切欠き２０６ｂ、第３切欠き２０６ｃ、及び第４切欠き２０６ｄが形成される。なお、これらの切欠きの数は４つに限定されるものでなく、後述する第１弾性機構部４００の構成、より詳細には、第１弾性体４１０の数に対応して設けられる。 As shown in FIGS. 1, 2, and 4, the flange 206 is formed with at least one notch along the circumferential direction on the outer periphery thereof. In one embodiment, as an example, the flange 206 is formed with four notches 206a, 206b, 206c, and 206d at equal intervals (90 degree intervals in the circumferential direction) along the circumferential direction on the outer periphery thereof. As shown in FIG. 1, conceptually, when the damper device 1 is viewed from the upper surface and divided into four regions I, II, III, and IV, each of which has a fan shape, the flange 206 has regions I to IV. The first notch 206a, the second notch 206b, the third notch 206c, and the fourth notch 206d are formed in association with each other, respectively. The number of these notches is not limited to four, and is provided corresponding to the configuration of the first elastic mechanism portion 400, which will be described later, and more specifically, the number of first elastic bodies 410.

It becomes possible. The flange 206 corresponds to the region I and has an engaging portion on one end side (engaging portion on the first one end side) 208a 1 and an engaging portion on the other end side facing the engaging portion (engaging portion on the first one end side) 208a 1 . It has an engaging portion) 208a 2 and is associated with the region II, the engaging portion on one end side (engaging portion on the second one end side) 208b 1 and the engaging portion on the other end side facing the engaging portion (engaging portion) 208b 1. It has a second engaging portion on the other end side) 208b 2, and is associated with the region III, and has an engaging portion on one end side (engaging portion on the third one end side) 208c 1 and the other facing the engaging portion 208c 1. It has an engaging portion on the end side (engaging portion on the third other end side) 208c 2, and is associated with the region IV, and the engaging portion on one end side (engaging portion on the fourth one end side) 208d. It has 1 and an engaging portion on the other end side (engaging portion on the fourth other end side) 208d 2 facing the same.

各一端側の係合部２０８ａ１、２０８ｂ１、２０８ｃ１、及び２０８ｄ１は、ともに同一の構成を有することができ、各他端側の係合部２０８ａ２、２０８ｂ２、２０８ｃ２、及び２０８ｄ２は、ともに同一の構成を有することができる。各一端側の係合部２０８ａ１、２０８ｂ１、２０８ｃ１、及び２０８ｄ１は、各他端側の係合部２０８ａ２、２０８ｂ２、２０８ｃ２、及び２０８ｄ２と左右対称の構成を有することができる。 The engaging portions 208a 1 , 208b 1 , 208c 1 , and 208d 1 on each one end side can all have the same configuration, and the engaging portions 208a 2 , 208b 2 , 208c 2, and 208d on the other end side, respectively. 2 can both have the same configuration. The engaging portions 208a 1 , 208b 1 , 208c 1 , and 208d 1 on each one end side may have a symmetrical configuration with the engaging portions 208a 2 , 208b 2 , 208c 2 , and 208d 2 on the other end side. it can.

また、外ハブ２００は、径方向内側に延びる第１噛合歯２０２が複数形成されている。複数の第１噛合歯２０２は、後述する内ハブ３００に設けられる第２噛合歯３０２に噛合するように構成される。 Further, the outer hub 200 is formed with a plurality of first meshing teeth 202 extending inward in the radial direction. The plurality of first meshing teeth 202 are configured to mesh with the second meshing teeth 302 provided on the inner hub 300, which will be described later.

１−３．内ハブ３００
内ハブ３００は、例えば、金属材料により形成され、主に図２、図４及び図５に示すように、略円筒状の円筒部３０１と略環状の第２噛合歯３０２を含み、回転軸Ｏの周りにディスクプレート１００（第１ディスクプレート１００Ａ及び第２ディスクプレート１００Ｂ）及び外ハブ２００に対して相対回転可能に設けられる。また、内ハブ３００は、円筒部３０１に形成された貫通孔３０１ｘに、変速機（図示せず）の入力軸（図示せず）を種々の連結要素１０００を介してスプライン結合させることができる。 1-3. Inner hub 300
The inner hub 300 is formed of, for example, a metal material and mainly includes a substantially cylindrical cylindrical portion 301 and a substantially annular second meshing tooth 302 as shown in FIGS. 2, 4 and 5, and the rotation shaft O Around the disc plate 100 (first disc plate 100A and second disc plate 100B) and the outer hub 200 are provided so as to be rotatable relative to each other. Further, the inner hub 300 can spline connect the input shaft (not shown) of the transmission (not shown) to the through hole 301x formed in the cylindrical portion 301 via various connecting elements 1000.

また、内ハブ３００における第２噛合歯３０２は、内ハブ３００の外周面全体に渡って構成されるものではなく、部分的に設けられる。具体的には、後述する切欠き３０６ａ及び切欠き３０６ｃも内ハブ３００の外周面に形成される関係で、第２噛合歯３０２は、内ハブ３００を上面からみて、領域ＩＩ及びＩＶに対応する位置にのみ設けられる。 Further, the second meshing tooth 302 in the inner hub 300 is not formed over the entire outer peripheral surface of the inner hub 300, but is partially provided. Specifically, since the notch 306a and the notch 306c, which will be described later, are also formed on the outer peripheral surface of the inner hub 300, the second meshing tooth 302 corresponds to the regions II and IV when the inner hub 300 is viewed from the upper surface. Provided only in position.

また、内ハブ３００は、図３に示すように、外ハブ２００に対し径方向内側に配され、且つ、内ハブ３００の第２噛合歯３０２と外ハブ２００の第１噛合歯２０２は、回転軸Ｏに対し、同一の軸方向位置に位置決めされている。これにより、第２噛合歯３０２と第１噛合歯２０２は相互に噛合可能となる。なお、第１噛合歯２０２と第２噛合歯３０２とは、領域ＩＩ及びＩＶにおいてのみ噛合可能となるため、第１噛合歯２０２及び第２噛合歯３０２への応力集中に伴うこれらの欠損等を効率的に防止するため、これらの強度を向上させるべく、第１噛合歯２０２及び第２噛合歯３０２には適宜焼入れ処理等が施されることが好ましい。ところで、第２噛合歯３０２の一部は、外ハブ２００と内ハブ３００とが一体的に回転している場合には（両者が相対回転していない場合には）、後述する第２弾性機構部５００における第３シート部材５３０に当接している。これにより、外ハブ２００と内ハブ３００とが相対回転し始めると、第２弾性機構部５００における第２弾性体５１０が、外ハブ２００と内ハブ３００との間で挟圧（圧縮変形）させられるように構成されている。 Further, as shown in FIG. 3, the inner hub 300 is arranged radially inward with respect to the outer hub 200, and the second meshing tooth 302 of the inner hub 300 and the first meshing tooth 202 of the outer hub 200 rotate. It is positioned at the same axial position with respect to the axis O. As a result, the second meshing tooth 302 and the first meshing tooth 202 can be meshed with each other. Since the first meshing tooth 202 and the second meshing tooth 302 can be meshed only in the regions II and IV, these defects due to stress concentration on the first meshing tooth 202 and the second meshing tooth 302, etc. In order to prevent these efficiently, it is preferable that the first meshing tooth 202 and the second meshing tooth 302 are appropriately hardened or the like in order to improve their strength. By the way, a part of the second meshing tooth 302 is a second elastic mechanism described later when the outer hub 200 and the inner hub 300 are integrally rotating (when both are not relatively rotating). It is in contact with the third sheet member 530 in the portion 500. As a result, when the outer hub 200 and the inner hub 300 start to rotate relative to each other, the second elastic body 510 in the second elastic mechanism portion 500 causes the outer hub 200 and the inner hub 300 to be pinched (compressed and deformed). It is configured to be.

また、内ハブ３００には、図２、図４、及び図５に示すように、その外周において、周方向に沿って、後述する第２弾性機構部５００を収容するための、少なくとも１つの切欠きが形成される。一実施形態では、一例として、内ハブ３００には、その外周において周方向に沿って等間隔で２つの切欠き３０６ａ及び３０６ｃが形成される。つまり、図２に示すように、内ハブ３００を上面からみて、領域Ｉに対応して第１切欠き３０６ａ、領域ＩＩＩに対応して第２切欠き３０６ｃが各々形成される。なお、これらの切欠きは、領域Ｉ及びＩＩＩに限定して設けられるものではなく、前述の第２噛合歯３０２が設けられる場所に合せて、適宜に変更することができる。 Further, as shown in FIGS. 2, 4, and 5, the inner hub 300 has at least one cut on the outer periphery thereof for accommodating the second elastic mechanism portion 500, which will be described later, along the circumferential direction. A notch is formed. In one embodiment, as an example, the inner hub 300 is formed with two notches 306a and 306c at equal intervals along the circumferential direction on the outer periphery thereof. That is, as shown in FIG. 2, when the inner hub 300 is viewed from the upper surface, the first notch 306a is formed corresponding to the region I, and the second notch 306c is formed corresponding to the region III. It should be noted that these notches are not limited to the regions I and III, and can be appropriately changed according to the location where the above-mentioned second meshing tooth 302 is provided.

さらに、内ハブ３００には、図２及び図５に示すように、後述する第２弾性機構部５００に含まれる第２シート部材５２０を径方向内側から支持する第１平坦面３０７、及び内ハブ３００による後述する第２弾性体５１０への干渉を防止する第２平坦面３０８、を有する。なお、第１平坦面３０７の形状は、第２シート部材５２０の形状に合せて適宜変更することができる。 Further, as shown in FIGS. 2 and 5, the inner hub 300 includes a first flat surface 307 that supports the second sheet member 520 included in the second elastic mechanism portion 500, which will be described later, from the inside in the radial direction, and the inner hub. It has a second flat surface 308, which prevents the 300 from interfering with the second elastic body 510 described later. The shape of the first flat surface 307 can be appropriately changed according to the shape of the second sheet member 520.

１−４．第１弾性機構部４００
第１弾性機構部４００は、図１及び図２に示すように、コイルスプリングが主に用いられる第１弾性体４１０、及び第１弾性体を支持する第１シート部材４２０（第１シート部材４２０ｘ並びに第２シート部材４２０ｙ）から主に構成される。なお、図１及び図２においては、１つのコイルスプリングが用いられる一例が示されているが、これに限定されず、例えば、２つのコイルスプリングを直列に配置してもよい。 1-4. First elastic mechanism part 400
As shown in FIGS. 1 and 2, the first elastic mechanism portion 400 includes a first elastic body 410 in which a coil spring is mainly used, and a first seat member 420 (first seat member 420x) that supports the first elastic body. It is mainly composed of the second sheet member 420y). Note that, although FIGS. 1 and 2 show an example in which one coil spring is used, the present invention is not limited to this, and for example, two coil springs may be arranged in series.

そして、図１及び図２に示した実施形態では、一例として、ディスクプレート１００には、４つの収容領域、すなわち、第１収容領域１０２ａ〜第４収容領域１０２ｄ（外ハブ２００には、４つの切欠き、すなわち、第１切欠き２０６ａ〜第４切欠き２０６ｄ）が形成されるので、これら４つの収容領域の各々に、つまり各領域Ｉ〜ＩＶに対応付けて、１つの第１弾性体４１０が収容される。また、各領域Ｉ〜ＩＶにおいて、第１弾性体４１０は、その両端を一対の第１シート部材４２０（第１シート部材４２０ｘ及び第２シート部材４２０ｙ）に支持される。 Then, in the embodiment shown in FIGS. 1 and 2, as an example, the disc plate 100 has four accommodating areas, that is, the first accommodating area 102a to the fourth accommodating area 102d (four in the outer hub 200). Since the notch, that is, the first notch 206a to the fourth notch 206d) is formed, one first elastic body 410 is associated with each of these four accommodating regions, that is, each region I to IV. Is housed. Further, in each region I to IV, both ends of the first elastic body 410 are supported by a pair of first sheet members 420 (first sheet member 420x and second sheet member 420y).

ここで、領域Ｉに着目すると、第１弾性体４１０を支持する第１シート部材４２０の一方（第１シート部材４２０ｘ）は、ディスクプレート１００に設けられる第１の一端面１０４ａ１、及びハブ２００に設けられる第１の一端側の係合部２０８ａ１と、各々係合する。また、第１弾性体４１０を支持する第１シート部材４２０の他方（第１シート部材４２０ｙは、ディスクプレート１００に設けられる第１の他端面１０４ａ２、及びハブ２００に設けられる第１の他端側の係合部２０８ａ２と、各々係合する。 Here, focusing on the region I, one of the first sheet members 420 (first sheet member 420x) supporting the first elastic body 410 is a first one end surface 104a 1 provided on the disc plate 100 and a hub 200. Each engages with the engaging portion 208a 1 on the one end side provided in the above. Further, the other side of the first sheet member 420 that supports the first elastic body 410 (the first sheet member 420y is the first other end surface 104a2 provided on the disc plate 100 and the first other end side provided on the hub 200). Each engages with the engaging portion 208a 2 .

なお、図４に示すように、第１シート部材４２０（第１シート部材４２０ｘ及び第２シート部材４２０ｙ）には第１溝部４２２が設けられ、当該第１溝部４２２に、外ハブ２００に設けられる第１の一端側の係合部２０８ａ１、及び第１の他端側の係合部２０８ａ２が各々収容されて、第１シート部材４２０と外ハブ２００が係合可能となっている。なお、領域Ｉについて説明した上記構成は、領域ＩＩ〜ＩＶにおいても同様である。 As shown in FIG. 4, the first seat member 420 (the first seat member 420x and the second seat member 420y) is provided with the first groove portion 422, and the first groove portion 422 is provided with the outer hub 200. The engaging portion 208a 1 on the first one end side and the engaging portion 208a 2 on the other end side of the first end are accommodated respectively, so that the first seat member 420 and the outer hub 200 can be engaged with each other. The above configuration described for region I is the same for regions II to IV.

以上の構成により、第１弾性体４１０は、第１シート部材４２０を介して、ディスクプレート１００と外ハブ２００とを、回転方向に弾性連結させることが可能となっている。つまり、エンジンやモータ等の駆動源からの動力が、ディスクプレート１００、第１シート部材４２０（第１シート部材４２０ｘ）、第１弾性体４１０、第１シート部材４２０（第１シート部材４２０ｙ）、及び外ハブ２００の順に伝達された上で、ディスクプレート１００と外ハブ２００とが互いに相対回転すると、第１弾性体４１０が圧縮変形させられることでトルク変動を吸収する。このように、第１弾性体４１０を含む第１弾性機構部４００は、ダンパ装置１におけるメインダンパ機能を有するものと捉えることができる。 With the above configuration, the first elastic body 410 can elastically connect the disc plate 100 and the outer hub 200 in the rotational direction via the first sheet member 420. That is, the power from the drive source such as the engine or the motor is the disc plate 100, the first seat member 420 (first seat member 420x), the first elastic body 410, the first seat member 420 (first seat member 420y), When the disc plate 100 and the outer hub 200 rotate relative to each other after being transmitted in the order of the outer hub 200 and the outer hub 200, the first elastic body 410 is compressively deformed to absorb torque fluctuations. As described above, the first elastic mechanism unit 400 including the first elastic body 410 can be regarded as having the main damper function in the damper device 1.

１−５．第２弾性機構部５００
第２弾性機構部５００は、図１、図２、図４、及び図５に示すように、前述の第１弾性機構部４００よりも径方向内側に配置されており、コイルスプリングが主に用いられる２つの第２弾性体５１０（第２弾性体５１０ｘ及び第２弾性体５１０ｙ）、２つの第２弾性体５１０の間に配置され２つの第２弾性体５１０を支持する（第２弾性体５１０ｘの他端及び第２弾性体５１０ｙの一端を支持する）第２シート部材５２０、第２弾性体５１０ｘの一端を支持する第３シート部材５３０、及び第２弾性体５１０ｙの他端を支持する第４シート部材５４０、から主に構成される。第２弾性機構部５００は、内ハブ３００に設けられる２つの切欠き３０６ａ及び３０６ｃにそれぞれ収容される。つまり、２つの第２弾性体５１０、１つの第２シート部材５２０、１つの第３シート部材５３０、及び１つの第４シート部材５４０を１つの第２弾性機構部５００のユニットと捉えることができる。 1-5. Second elastic mechanism part 500
As shown in FIGS. 1, 2, 4, and 5, the second elastic mechanism portion 500 is arranged radially inside the first elastic mechanism portion 400 described above, and is mainly used by a coil spring. Two second elastic bodies 510 (second elastic body 510x and second elastic body 510y) are arranged between two second elastic bodies 510 and support two second elastic bodies 510 (second elastic body 510x). (Supports the other end of the second elastic body 510y), the third sheet member 530 that supports one end of the second elastic body 510x, and the second that supports the other end of the second elastic body 510y. It is mainly composed of 4 seat members 540. The second elastic mechanism portion 500 is housed in two notches 306a and 306c provided in the inner hub 300, respectively. That is, the two second elastic bodies 510, one second sheet member 520, one third sheet member 530, and one fourth sheet member 540 can be regarded as one unit of the second elastic mechanism unit 500. ..

なお、１つの第２弾性機構部５００のユニットにおいては、図２及び図５等で示すように、２つの第２弾性体５１０が用いられる一例が示されているが、これに限定されず、第１噛合歯２０２及び第２噛合歯３０２の強度が許容され（上記のような欠損等の問題が生じない）、且つ内ハブ３００に設けられる２つの切欠き３０６ａ及び３０６ｃの大きさに適合する限りにおいて、例えば、３つの第２弾性体５１０（コイルスプリング）を直列に配置してもよい。また、図２及び図５等で示すように、ダンパ装置１において、２つの第２弾性機構部５００のユニットが用いられる一例が示されているが、これに限定されず、例えば、領域Ｉに対応する位置にのみ、当該ユニットを配するような構成とする等、必要とされる内ハブ３００における第２噛合歯３０２の歯数との関係で、当該ユニットの数を適宜選択すればよい。 In one unit of the second elastic mechanism unit 500, as shown in FIGS. 2 and 5, an example in which two second elastic bodies 510 are used is shown, but the present invention is not limited to this. The strength of the first meshing tooth 202 and the second meshing tooth 302 is allowed (the above-mentioned problems such as defects do not occur), and the size of the two notches 306a and 306c provided in the inner hub 300 is adapted. As long as, for example, three second elastic bodies 510 (coil springs) may be arranged in series. Further, as shown in FIGS. 2 and 5, an example in which two units of the second elastic mechanism unit 500 are used in the damper device 1 is shown, but the present invention is not limited to this, and for example, in the region I. The number of the units may be appropriately selected in relation to the number of teeth of the second meshing teeth 302 in the required inner hub 300, such as arranging the units only at the corresponding positions.

第２弾性体５１０に用いられるコイルスプリングのばね剛性は、基本的に、後述する図８に示すような捩り特性を実現させるために、第１弾性機構部４００において用いられるコイルスプリングのばね剛性よりも低く設定される。 The spring rigidity of the coil spring used in the second elastic body 510 is basically higher than the spring rigidity of the coil spring used in the first elastic mechanism portion 400 in order to realize the torsional characteristics as shown in FIG. 8 described later. Is also set low.

第２シート部材５２０は、図５に示すように、２つの第２弾性体５１０を支持する側部５２２と、後述する中間部材６００の支持部６０４に対向する上部５２４と、内ハブ３００における第１平坦面３０７に支持される底部５２６を含む。なお、第２弾性体５１０が２つ直列に用いられる場合においては、１つの第２シート部材５２０が当該２つの第２弾性体５１０を支持すればよく、第２弾性体５１０が仮に３つ直列に用いられる場合においては、２つの第２シート部材５２０によって、当該３つの第２弾性体５１０が支持されることとなる（この場合、第２弾性体５１０、第２シート部材５２０、第２弾性体５１０、第２シート部材５２０、第２弾性体５１０、の並び順に直列的に配置される）。 As shown in FIG. 5, the second sheet member 520 has a side portion 522 that supports two second elastic bodies 510, an upper portion 524 that faces the support portion 604 of the intermediate member 600, which will be described later, and a second in the inner hub 300. 1 Includes a bottom 526 supported by a flat surface 307. When two second elastic bodies 510 are used in series, one second sheet member 520 may support the two second elastic bodies 510, and three second elastic bodies 510 may be in series. In the case of being used in the above, the three second elastic bodies 510 are supported by the two second sheet members 520 (in this case, the second elastic body 510, the second sheet member 520, and the second elastic body). The body 510, the second sheet member 520, and the second elastic body 510 are arranged in series in the order of arrangement).

図５に加えて、図６Ａ及び図６Ｂを参照しつつ、第２シート部材５２０の詳細を説明する。側部５２２は、径方向に対して所定角度α度傾いた傾斜形状を有して、２つの第２弾性体５１０を支持している。これにより、側部５２２は、第２弾性体５１０の径方向（径方向外側）への移動を規制することができる。なお、側部５２２には、第２弾性体５１０の内部に挿通される第１突起部５２５が設けられている。第１突起部５２５は、第３シート部材５３０に設けられる第２突起部５３５、及び第４シート部材５４０に設けられる第３突起部５４５にそれぞれ対応しており、２つの第２弾性体５１０が線間密着してしまうことを防止している。 In addition to FIG. 5, the details of the second seat member 520 will be described with reference to FIGS. 6A and 6B. The side portion 522 has an inclined shape inclined by a predetermined angle α degree with respect to the radial direction, and supports two second elastic bodies 510. As a result, the side portion 522 can restrict the movement of the second elastic body 510 in the radial direction (outward in the radial direction). The side portion 522 is provided with a first protrusion 525 that is inserted into the inside of the second elastic body 510. The first protrusion 525 corresponds to the second protrusion 535 provided on the third sheet member 530 and the third protrusion 545 provided on the fourth seat member 540, and the two second elastic bodies 510 correspond to each other. It prevents the lines from sticking to each other.

次に、上部５２４は、中間部材６００の支持部６０４に対向し、径方向外側に向かって拡開した凹部形状を呈している。上部５２４には、所定角度β度傾いた側面５２４ｘが設けられる。側面５２４ｘは、後述するとおり、中間部材６００に対して動力を伝達することで、中間部材６００を内ハブ３００及び第２弾性機構部５００とともに回転させる。なお、上部５２４の側面５２４ｘに係る所定角度βの大きさは、第２シート部材５２０の強度や材質、中間部材６００の強度や材質等を考慮して、適宜選択することができる。また、上部５２４の拡開した凹部形状も、これに限定されず、側面５２４ｘを有する限りにおいて、適宜に変更することができる。 Next, the upper portion 524 has a concave shape that faces the support portion 604 of the intermediate member 600 and expands outward in the radial direction. The upper portion 524 is provided with a side surface 524x inclined by a predetermined angle β degree. As will be described later, the side surface 524x transmits power to the intermediate member 600 to rotate the intermediate member 600 together with the inner hub 300 and the second elastic mechanism portion 500. The size of the predetermined angle β related to the side surface 524x of the upper portion 524 can be appropriately selected in consideration of the strength and material of the second sheet member 520, the strength and material of the intermediate member 600, and the like. Further, the shape of the expanded concave portion of the upper portion 524 is not limited to this, and can be appropriately changed as long as it has the side surface 524x.

次に、底部５２６は、前述した内ハブ３００の第１平坦面３０７に支持される。これにより、第２シート部材５２０は、内ハブ３００の外周面において、安定的に保持される。 Next, the bottom portion 526 is supported by the first flat surface 307 of the inner hub 300 described above. As a result, the second seat member 520 is stably held on the outer peripheral surface of the inner hub 300.

第３シート部材５３０は、内ハブ３００に設けられる２つの切欠き３０６ａ及び３０６ｃの一端側の端部に設けられ、第２弾性体５１０ｘの一端を支持する。なお、第３シート部材５３０は、第２弾性体５１０ｘを支持する面とは逆の面において、内ハブ３００の第２噛合歯３０２に当接可能となっている。他方、第４シート部材５４０は、内ハブ３００に設けられる２つの切欠き３０６ａ及び３０６ｃの他端側の端部に設けられ、第２弾性体５１０ｙの他端を支持する。なお、第３シート部材５３０及び第４シート部材５４０には、前述のとおり、第２突起部５３５及び第３突起部５４５が各々に設けられている。 The third sheet member 530 is provided at one end of two notches 306a and 306c provided in the inner hub 300, and supports one end of the second elastic body 510x. The third sheet member 530 can come into contact with the second meshing teeth 302 of the inner hub 300 on the surface opposite to the surface supporting the second elastic body 510x. On the other hand, the fourth seat member 540 is provided at the other end of the two notches 306a and 306c provided in the inner hub 300, and supports the other end of the second elastic body 510y. As described above, the third seat member 530 and the fourth seat member 540 are each provided with the second protrusion 535 and the third protrusion 545.

以上の構成により、第２弾性体５１０は、第２シート部材５２０、第３シート部材５３０、及び第４シート部材５４０を介して、外ハブ２００と内ハブ３００とを回転方向に弾性連結させることが可能となっている。つまり、前述のとおり、ディスクプレート１００から様々な構成要素を介して外ハブ２００に伝達される動力は、第３シート部材５３０、第２弾性体５１０ｘ、第２シート部材５２０、第２弾性体５１０ｙ、及び第４シート部材５４０の順に伝達された上で、外ハブ２００と内ハブ３００とが互いに相対回転すると、第２弾性体５１０ｘ及び第２弾性体５１０ｙが圧縮変形させられることでトルク変動を吸収する。このように、第２弾性体５１０（第２弾性体５１０ｘ及び第２弾性体５１０ｙ）を含む第２弾性機構部５００は、ダンパ装置１におけるプリダンパ機能を有するものと捉えることができる。 With the above configuration, the second elastic body 510 elastically connects the outer hub 200 and the inner hub 300 in the rotational direction via the second seat member 520, the third seat member 530, and the fourth seat member 540. Is possible. That is, as described above, the power transmitted from the disc plate 100 to the outer hub 200 via various components is the third sheet member 530, the second elastic body 510x, the second sheet member 520, and the second elastic body 510y. , And the fourth sheet member 540 are transmitted in this order, and when the outer hub 200 and the inner hub 300 rotate relative to each other, the second elastic body 510x and the second elastic body 510y are compressively deformed to cause torque fluctuation. Absorb. As described above, the second elastic mechanism portion 500 including the second elastic body 510 (the second elastic body 510x and the second elastic body 510y) can be regarded as having the pre-damper function in the damper device 1.

また、以上のとおり構成される第２弾性機構部５００は、図３に示すように、径方向において、外ハブ２００と内ハブ３００との間に配置される。つまり、外ハブ２００と内ハブ３００との間には、第２弾性機構部５００のみが配され、他の構成要素は配されていない。このような構成とすることで、ダンパ装置１は、軸方向において体格がコンパクトなものとなる。 Further, as shown in FIG. 3, the second elastic mechanism portion 500 configured as described above is arranged between the outer hub 200 and the inner hub 300 in the radial direction. That is, only the second elastic mechanism portion 500 is arranged between the outer hub 200 and the inner hub 300, and other components are not arranged. With such a configuration, the damper device 1 has a compact physique in the axial direction.

１−６．中間部材６００
中間部材６００は、図５、図７Ａ、及び図７Ｂに示すように、軸方向において内ハブ３００に隣接して配置される本体部６０２と、本体部６０２から軸方向に延び、第２弾性機構部５００における第２シート部材５２０を径方向外側から支持する支持部６０４と、を含む。 1-6. Intermediate member 600
As shown in FIGS. 5, 7A, and 7B, the intermediate member 600 extends axially from the main body portion 602 arranged adjacent to the inner hub 300 in the axial direction and the main body portion 602, and has a second elastic mechanism. A support portion 604 that supports the second seat member 520 in the portion 500 from the outside in the radial direction is included.

本体部６０２は、第２弾性機構部５００における第２弾性体５１０の軸方向の移動（例えば、図５においては、第２弾性体５１０の紙面右奥方向への移動）を規制することができる。 The main body portion 602 can regulate the axial movement of the second elastic body 510 in the second elastic mechanism portion 500 (for example, in FIG. 5, the movement of the second elastic body 510 in the right-back direction of the paper surface). ..

支持部６０４は、第２シート部材５２０の上部５２４に対応する部分であって、拡開した凹部形状を呈する当該上部５２４の形状に適合する凸部形状を呈することができる。これにより、支持部６０４は、第２シート部材５２０（ひいては、第２弾性体５１０）の径方向（径方向外側）への移動を規制している。また、図５に示すように、支持部６０４の当該凸部においては、上部５２４の側面５２４ｘに対応する面６０４ｘを有する。これにより、第２シート部５２０から動力が伝達可能とされて、内ハブ３００及び第２弾性機構部５００とともに一体的に回転することが可能となっている。 The support portion 604 is a portion corresponding to the upper portion 524 of the second sheet member 520, and can exhibit a convex portion shape that matches the shape of the upper portion 524 that exhibits an expanded concave shape. As a result, the support portion 604 regulates the movement of the second seat member 520 (and by extension, the second elastic body 510) in the radial direction (outward in the radial direction). Further, as shown in FIG. 5, the convex portion of the support portion 604 has a surface 604x corresponding to the side surface 524x of the upper portion 524. As a result, power can be transmitted from the second seat portion 520, and the inner hub 300 and the second elastic mechanism portion 500 can be integrally rotated.

なお、支持部６０４の形状は、凸部に限定されるものではなく、上部５２４の形状に合せて適宜変更することができる。また、中間部材６００、特に、支持部６０４は、第２シート部５２０、ひいては第２弾性体５１０の径方向（径方向外側）への動きを効率的に規制するために、少なくとも第２シート部材５２０よりも重量が重い材質のものを用いることが好ましい。 The shape of the support portion 604 is not limited to the convex portion, and can be appropriately changed according to the shape of the upper portion 524. Further, the intermediate member 600, particularly the support portion 604, is at least a second seat member in order to efficiently regulate the movement of the second seat portion 520 and, by extension, the second elastic body 510 in the radial direction (outward in the radial direction). It is preferable to use a material having a weight heavier than 520.

なお、一実施形態に係るダンパ装置１においては、第２シート部材５２０と中間部材６００とを別体のものを一例として示したが、これらを一体化したものを用いてもよい。 In the damper device 1 according to the embodiment, a separate body of the second seat member 520 and the intermediate member 600 is shown as an example, but an integrated device may be used.

以上のとおり、ダンパ装置１は、中間部材６００（本体部６０２）を、軸方向において内ハブ３００に隣接する位置（外ハブ２００及び内ハブ３００に対し、中間部材６００は異なる軸位置）に配するため、内ハブ３００の外周面上における前述の第２弾性機構部５００の配置場所について設計自由度を向上させることが可能となる。つまり、内ハブ３００の径方向外側に中間部材６００の本体部６０２が存在しない分、第２弾性機構部５００を、内ハブ３００における径方向外側（外ハブ２００に近づく側）に配置することが可能となる。その結果、第２弾性機構部５００における２つの第２弾性体５１０の合計ストローク（伸縮する方向に延びる、当該２つの第２弾性体５１０の合計長さ）を長く確保でき、第２弾性機構部５００に係るプリダンパ機能に対応する捩り角度幅を広く確保することが可能となる。 As described above, the damper device 1 arranges the intermediate member 600 (main body portion 602) at a position adjacent to the inner hub 300 in the axial direction (the intermediate member 600 has a different axial position from the outer hub 200 and the inner hub 300). Therefore, it is possible to improve the degree of freedom in designing the arrangement location of the second elastic mechanism portion 500 on the outer peripheral surface of the inner hub 300. That is, since the main body portion 602 of the intermediate member 600 does not exist on the radial outer side of the inner hub 300, the second elastic mechanism portion 500 can be arranged on the radial outer side (the side closer to the outer hub 200) of the inner hub 300. It will be possible. As a result, the total stroke of the two second elastic bodies 510 in the second elastic mechanism portion 500 (the total length of the two second elastic bodies 510 extending in the expansion / contraction direction) can be secured long, and the second elastic mechanism portion It is possible to secure a wide twist angle width corresponding to the pre-damper function according to 500.

２．ダンパ装置の動作
次に、上記構成を有するダンパ装置１の動作について、図８等を参照して説明する。図８は、一実施形態のダンパ装置１における捩り特性を模式的に示す概略特性図である。 2. Operation of Damper Device Next, the operation of the damper device 1 having the above configuration will be described with reference to FIG. 8 and the like. FIG. 8 is a schematic characteristic diagram schematically showing the torsional characteristics of the damper device 1 of the embodiment.

図１等に示される一実施形態に係るダンパ装置１は、図８に示すような捩り特性を有する。具体的には、第２弾性機構部５００によるプリダンパ機能が発現されるプリダンパステージと、第１弾性機構部４００によるメインダンパ機能が発現されるメインダンパステージと、に分けられる。なお、前述のとおり、第２弾性機構部５００に含まれる第２弾性体５１０のばね剛性は、第１弾性機構部４００に含まれる第１弾性体４１０のばね剛性よりも低いため、プリダンパステージにおける捩り特性の方がメインダンパステージにおける捩り特性よりも緩やかに設定される。また、ダンパ装置１は、前述のとおり、第２弾性機構部５００には２つの第２弾性体５１０が含まれ、且つ、２つの弾性体５１０の合計ストロークが長く確保されているため、プリダンパステージに対応する捩り角度幅が広く確保されている。これにより、ダンパ装置１全体としてのダンパ機能を向上させている。 The damper device 1 according to the embodiment shown in FIG. 1 and the like has a twisting characteristic as shown in FIG. Specifically, it is divided into a pre-damper stage in which the pre-damper function is expressed by the second elastic mechanism unit 500 and a main damper stage in which the main damper function is expressed by the first elastic mechanism unit 400. As described above, the spring rigidity of the second elastic body 510 included in the second elastic mechanism portion 500 is lower than the spring rigidity of the first elastic body 410 included in the first elastic mechanism portion 400, and therefore the pre-damper stage. The torsional characteristic in is set more gently than the torsional characteristic in the main damper stage. Further, as described above, in the damper device 1, the second elastic mechanism portion 500 includes two second elastic bodies 510, and the total stroke of the two elastic bodies 510 is secured for a long time, so that the pre-damper device 1 is a pre-damper. A wide twist angle width corresponding to the stage is secured. As a result, the damper function of the damper device 1 as a whole is improved.

３．変形例
次に、別の実施形態に係るダンパ装置１の構成とその特性について、図９等を参照して説明する。図９は、別の実施形態のダンパ装置１における捩り特性を模式的に示す概略特性図である。 3. 3. Modification Example Next, the configuration of the damper device 1 and its characteristics according to another embodiment will be described with reference to FIG. 9 and the like. FIG. 9 is a schematic characteristic diagram schematically showing the torsional characteristics of the damper device 1 of another embodiment.

別の実施形態に係るダンパ装置１としては、第２弾性機構部５００における２つの第２弾性体５１０のうちの一方の（例えば、第２弾性体５１０ｘ）のばね剛性と、他方（第２弾性体５１０ｙ）のばね剛性とを異ならせる形態が採用される。具体的には、第２弾性体５１０ｘのばね剛性を、第２弾性体５１０ｙのばね剛性よりも低くした上で、第２弾性体５１０のばね剛性を第１弾性機構部４００における第１弾性体４１０のばね剛性と同じにした場合が採用されうる。 As the damper device 1 according to another embodiment, the spring rigidity of one of the two second elastic bodies 510 (for example, the second elastic body 510x) in the second elastic mechanism portion 500 and the other (second elastic body 510x) A form different from the spring rigidity of the body 510y) is adopted. Specifically, the spring rigidity of the second elastic body 510x is made lower than the spring rigidity of the second elastic body 510y, and then the spring rigidity of the second elastic body 510 is set to the first elastic body in the first elastic mechanism portion 400. The case where the spring rigidity of 410 is the same can be adopted.

このような構成が採用される別の実施形態に係るダンパ装置１においては、図９に示すような捩り特性を有する。具体的には、プリダンパステージが、第２弾性体５１０ｘに対応する第１プリダンパステージと、第２弾性体５１０ｙに対応する第２プリダンパステージと、に分けられる。このように、第２弾性体５１０ｙと第１弾性体４１０のばね剛性を同じにすることで、プリダンパステージとメインダンパステージとの間のトルク段差を解消することが可能となる。 The damper device 1 according to another embodiment in which such a configuration is adopted has a twisting characteristic as shown in FIG. Specifically, the pre-damper stage is divided into a first pre-damper stage corresponding to the second elastic body 510x and a second pre-damper stage corresponding to the second elastic body 510y. By making the spring rigidity of the second elastic body 510y and the first elastic body 410 the same in this way, it is possible to eliminate the torque step between the pre-damper stage and the main damper stage.

以上、前述の通り、様々な実施形態を例示したが、上記実施形態はあくまで一例であって、発明の範囲を限定することは意図していない。上記実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置換、変更を行うことができる。また、各構成や、形状、大きさ、長さ、幅、厚さ、高さ、数等は適宜変更して実施することができる。 As described above, various embodiments have been exemplified, but the above embodiments are merely examples and are not intended to limit the scope of the invention. The above-described embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
