Description

本発明は、遠心力によりクラッチシューが摩擦材を介して従動側回転部材の内周壁面と当接又は離間することにより、駆動手段の駆動力を伝達又は遮断させ得る遠心クラッチ装置に関するものである。   The present invention relates to a centrifugal clutch device capable of transmitting or interrupting a driving force of a driving means by causing a clutch shoe to contact or separate from an inner peripheral wall surface of a driven side rotation member via a friction material by a centrifugal force. .

車両のエンジンの駆動力を駆動輪に伝達すべき伝達経路には、通常、クラッチ装置が配設されており、主なクラッチ装置として遠心力を利用して駆動力の伝達又は遮断を行わせる遠心クラッチ装置が挙げられる。かかる遠心クラッチ装置は、例えば特許文献１にて開示されているように、エンジンのクランク軸と連結されたドライブプレートと、該ドライブプレートに揺動自在に配設されたクラッチシューと、該クラッチシューが遠心力にて揺動した際に摩擦材（フェーシング）を介して当接可能な内周壁面を有するハウジングとを具備していた。   A clutch device is usually disposed in a transmission path through which the driving force of the vehicle engine should be transmitted to the driving wheels, and the centrifugal force is used as a main clutch device to transmit or shut off the driving force. A clutch device may be mentioned. Such a centrifugal clutch device includes, as disclosed in, for example, Patent Document 1, a drive plate coupled to an engine crankshaft, a clutch shoe that is swingably disposed on the drive plate, and the clutch shoe. And a housing having an inner peripheral wall surface that can be contacted via a friction material (facing) when it is swung by centrifugal force.

そして、エンジンの駆動に伴いドライブプレートが回転すると、クラッチシューに遠心力が付与されて揺動するので、当該ドライブプレートの回転数が一定値を超えると摩擦材がハウジングの内周壁面に当接して動力が伝達されることとなる。クラッチシューの内周壁面と対向する面は、ハウジングの内周壁面に倣って弧状に形成されており、当該弧状面に摩擦材が固着されている。
特開２００４−３６８０６号公報 When the drive plate rotates as the engine is driven, centrifugal force is applied to the clutch shoe and swings. Therefore, when the rotational speed of the drive plate exceeds a certain value, the friction material comes into contact with the inner peripheral wall surface of the housing. Power is transmitted. A surface facing the inner peripheral wall surface of the clutch shoe is formed in an arc shape following the inner peripheral wall surface of the housing, and a friction material is fixed to the arc-shaped surface.

以下、本発明の実施形態について図面を参照しながら具体的に説明する。
本実施形態に係る遠心クラッチ装置は、車両のエンジンの駆動力を駆動輪に伝達すべき伝達経路に配設され、遠心力によりクラッチシューが摩擦材を介してハウジングの内周壁面と当接又は離間することにより、エンジンの駆動力を伝達又は遮断させ得る乾式と称されるものであり、図１及び図２に示すように、駆動側回転部材としてのドライブプレート１と、クラッチシュー２と、従動側回転部材としてのハウジング３とから主に構成されている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The centrifugal clutch device according to the present embodiment is disposed in a transmission path where the driving force of the engine of the vehicle should be transmitted to the driving wheels, and the clutch shoe is brought into contact with the inner peripheral wall surface of the housing through the friction material by the centrifugal force. It is called a dry type that can transmit or cut off the driving force of the engine by being separated, and as shown in FIGS. 1 and 2, a drive plate 1 as a driving side rotating member, a clutch shoe 2, It is mainly comprised from the housing 3 as a driven side rotation member.

ドライブプレート１は、エンジンと連結されたクラッチ軸Ｌ２を中心として回転自在な円板状部材から成り、当該エンジンの駆動により回転可能とされている。かかるドライブプレート１は、その周縁がハウジング３の内周壁面３ａと対向するよう配設されており、摩擦材４が内周壁面３ａに当接した状態で当該ハウジング３と共に回転し、当該摩擦材４が内周壁面３ａから離間した状態でハウジング３とは独立して回転可能とされている。   The drive plate 1 is composed of a disk-like member that is rotatable about a clutch shaft L2 connected to the engine, and can be rotated by driving the engine. The drive plate 1 is disposed so that the peripheral edge thereof faces the inner peripheral wall surface 3a of the housing 3, and rotates with the housing 3 in a state where the friction material 4 is in contact with the inner peripheral wall surface 3a. 4 is rotatable independently of the housing 3 in a state of being separated from the inner peripheral wall surface 3a.

また、ドライブプレート１には、クラッチシュー２が周方向に略等間隔で３つ形成されている。各クラッチシュー２は、鉄製板材を複数枚積層させて成るもので、所定の重量を有する。かかるクラッチシュー２は、揺動軸Ｌ１を中心として揺動自在とされており、ドライブプレート１が回転することにより遠心力が付与されると、当該ドライブプレート１の外径側（外側）に揺動可能とされている。尚、クラッチシュー２は、複数の板状部材を積層したものに代え、一材料にて一体的に成形されたものであってもよい。   The drive plate 1 is formed with three clutch shoes 2 at substantially equal intervals in the circumferential direction. Each clutch shoe 2 is formed by laminating a plurality of iron plate materials and has a predetermined weight. The clutch shoe 2 is swingable about the swing shaft L1. When a centrifugal force is applied as the drive plate 1 rotates, the clutch shoe 2 swings toward the outer diameter side (outside) of the drive plate 1. It is possible to move. In addition, the clutch shoe 2 may be integrally formed of one material instead of a laminate of a plurality of plate-like members.

一方、ハウジング３は、既述の如くドライブプレート１を独立して回転自在に収容するとともに、クラッチシュー２の揺動方向に内周壁面３ａを有したものであり、出力部材５と連結されている。かかる出力部材５は、車両の駆動輪と連結されており、摩擦材４が内周壁面３ａに当接した状態でドライブプレート１とハウジング３とが共に回転することにより、エンジンの駆動力が出力部材５を介して駆動輪に伝達されるよう構成されている。   On the other hand, the housing 3 houses the drive plate 1 independently and rotatably as described above, and has an inner peripheral wall surface 3a in the swinging direction of the clutch shoe 2, and is connected to the output member 5. Yes. The output member 5 is connected to drive wheels of the vehicle, and the drive force of the engine is output when the drive plate 1 and the housing 3 rotate together with the friction material 4 in contact with the inner peripheral wall surface 3a. It is configured to be transmitted to the drive wheels via the member 5.

摩擦材４は、クラッチシュー２における内周壁面３ａと対向した面に固着され、当該クラッチシュー２が遠心力で揺動した際に当該内周壁面３ａと当接してエンジンの駆動力をハウジング３に伝達して回転させるためのものである。即ち、摩擦材４が内周壁面３ａと当接することにより、その摩擦力にてドライブプレート１側の回転力がハウジング３側に伝達されるのである。   The friction material 4 is fixed to a surface of the clutch shoe 2 facing the inner peripheral wall surface 3a. When the clutch shoe 2 is swung by a centrifugal force, the friction material 4 comes into contact with the inner peripheral wall surface 3a to transmit the driving force of the engine to the housing 3. It is for transmitting to and rotating. That is, when the friction material 4 comes into contact with the inner peripheral wall surface 3a, the rotational force on the drive plate 1 side is transmitted to the housing 3 side by the friction force.

更に、隣り合うクラッチシュー２間には、コイルスプリングＳが連結されており、ドライブプレート１の回転が低下して遠心力が低減した際、各々のクラッチシュー２が初期位置に戻るよう構成されている。尚、同図中符号６は、クラッチシュー２が軸方向に抜けてしまうのを防止するための抜け止め部材を示しており、この抜け止め部材６とドライブプレート１との間に複数の鉄製板材を積層して成るクラッチシュー２が挟持されるよう構成されている。   Further, a coil spring S is connected between the adjacent clutch shoes 2, and each clutch shoe 2 returns to the initial position when the rotation of the drive plate 1 is reduced and the centrifugal force is reduced. Yes. Reference numeral 6 in the figure denotes a retaining member for preventing the clutch shoe 2 from coming off in the axial direction. A plurality of iron plate members are provided between the retaining member 6 and the drive plate 1. The clutch shoe 2 formed by laminating the layers is sandwiched.

ここで、本実施形態に係る遠心クラッチ装置においては、図３で示すように、ドライブプレート１を折り曲げ形成して得られたストッパ手段７を具備している。かかるストッパ手段７は、クラッチシュー２と干渉して当該クラッチシュー２の揺動角度を規制し、摩擦材４が所定量以上に摩耗したクラッチシュー２が内周壁面３ａと接触してしまうのを防止するもので、ドライブプレート１の所定部位をクラッチシュー２が形成された方向へ略垂直に立ち上げる如く折り曲げ加工して得られたものである（図２の断面図参照）。   Here, the centrifugal clutch device according to the present embodiment includes stopper means 7 obtained by bending the drive plate 1 as shown in FIG. The stopper means 7 interferes with the clutch shoe 2 to regulate the swing angle of the clutch shoe 2, and the clutch shoe 2 with the friction material 4 worn more than a predetermined amount comes into contact with the inner peripheral wall surface 3a. This is obtained by bending a predetermined portion of the drive plate 1 so as to rise substantially vertically in the direction in which the clutch shoe 2 is formed (see the sectional view of FIG. 2).

即ち、摩擦材４の摩耗が所定量より少なく、クラッチシュー２が揺動した際、当該摩擦材４が内周壁面３ａと接触することにより当該クラッチシュー２が直接内周壁面３ａと接触しない状態では、図４に示すように、ストッパ手段７はａ方向へ揺動したクラッチシュー２と干渉しない一方、摩擦材４が所定量以上摩耗した状態にてクラッチシュー２が同方向へ揺動した際、図５で示すように、当該クラッチシュー２の所定位置に形成された当接部位２ａがストッパ手段７と当接して干渉し、それ以上の揺動が規制されるのである。   That is, when the friction material 4 wears less than a predetermined amount and the clutch shoe 2 swings, the friction material 4 comes into contact with the inner peripheral wall surface 3a, so that the clutch shoe 2 does not directly contact the inner peripheral wall surface 3a. Then, as shown in FIG. 4, the stopper means 7 does not interfere with the clutch shoe 2 swinging in the direction a, while the clutch shoe 2 swings in the same direction while the friction material 4 is worn over a predetermined amount. As shown in FIG. 5, the contact portion 2a formed at a predetermined position of the clutch shoe 2 contacts and interferes with the stopper means 7, and further swinging is restricted.

これにより、ストッパ手段としてピンをカシメ固定させる従来のものに比べ、部品点数の増加を回避しつつ揺動したクラッチシュー２がハウジング３の内周壁面３ａに直接接触してしまうのを確実に防止することができる。尚、ストッパ手段７は、ドライブプレート１を折り曲げ形成して得られたものであれば足り、当該ドライブプレート１の周縁部を立ち上げる如く折り曲げ加工したもの、或いは強度を更に強化すべく種々形状に折り曲げ加工したもの等としてもよい。   As a result, it is possible to reliably prevent the swinging clutch shoe 2 from coming into direct contact with the inner peripheral wall surface 3a of the housing 3 while avoiding an increase in the number of parts, as compared with the conventional device in which the pin is caulked and fixed as the stopper means. can do. It is sufficient that the stopper means 7 is obtained by bending the drive plate 1, and the stopper means 7 is bent so that the peripheral edge of the drive plate 1 is raised, or has various shapes to further enhance the strength. It may be a bent one.

また、ストッパ手段７は、ドライブプレート１の他の位置のプレス加工（例えば、中心部近傍の段を形成するプレス加工等）と同時に折り曲げ加工にて得られるよう構成するのが好ましい。この場合、それぞれの工程を有したものに比べ、製造工程を削減して製造コストを更に低減させることができる。更に、本実施形態においては、クラッチシュー２が、鉄製板材を複数枚積層させて成るので、亜鉛等に比べ熱に強く加工性に富んだクラッチシュー２を得ることができる。   Further, the stopper means 7 is preferably configured to be obtained by bending at the same time as pressing at another position of the drive plate 1 (for example, pressing to form a step near the center). In this case, compared with what has each process, a manufacturing process can be reduced and manufacturing cost can be reduced further. Furthermore, in the present embodiment, the clutch shoe 2 is formed by laminating a plurality of iron plate materials, so that it is possible to obtain the clutch shoe 2 that is resistant to heat and rich in workability compared to zinc or the like.

以上、本実施形態について説明したが、本発明はこれに限定されるものではなく、例えばドライブプレートにクラッチシューが１、２又は４つ以上配設されたもの、或いは湿式遠心クラッチ装置（オイルで満たされた形態のもの）等に適用することができる。また、ストッパ手段７の形状や形成位置等は、本発明の所望機能が維持されれば、他の形態としてもよい。   Although the present embodiment has been described above, the present invention is not limited to this. For example, a drive plate having one, two, or four or more clutch shoes or a wet centrifugal clutch device (oil In a filled form). The stopper means 7 may have other shapes and shapes as long as the desired function of the present invention is maintained.

駆動側回転部材を折り曲げ形成して得られたストッパ手段を具備した遠心クラッチ装置であれば、外観形状が異なるもの或いは他の機能が付加されたもの等にも適用することができる。   As long as the centrifugal clutch device is provided with stopper means obtained by bending the driving side rotating member, the centrifugal clutch device can be applied to one having a different external shape or having other functions.
