Abstract

<P>PROBLEM TO BE SOLVED: To provide a clutch release bearing capable of suitably assembling while sealing performance is secured. <P>SOLUTION: At the time of inserting, a diameter reduced section 17a is fitted into the inner periphery of a short cylinder 16c of the seal member 16, and therefore, a seal member 16 becomes coaxial with an outer ring 11 and a seal member pushing fixture 17 if the ring 11 and the fixture 17 are coaxially arranged. When the seal member pushing fixture 17 is relatively moved to the outer ring 11 in this state, the seal member 16 pushed on its whole periphery by means of the end face of the seal member pushing fixture 17 or a stepped part of the diameter reduction section 17a crosses a raceway surface 11d in a stable state. A padding section 16d is brought into close contact with a groove 11c for seal assembling, and the accurate assembling of the seal member 16 can be achieved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、車両などに用いられるクラッチレリーズ軸受及びシール部材押し込み治具に関する。   The present invention relates to a clutch release bearing and a seal member pushing jig used in a vehicle or the like.

車両等に搭載され摩擦板を用いた動力断続装置であるクラッチを動作させる場合において、入力部材であるレリーズフォークで、回転部材であるクラッチカバーのダイヤフラムスプリングを軸線方向に押圧することにより、スプリングの付勢力を摩擦板から解除して動力伝達の切り離しが行なわれている。   When operating a clutch that is a power interrupting device mounted on a vehicle or the like using a friction plate, the release fork that is an input member presses the diaphragm spring of the clutch cover that is a rotating member in the axial direction, thereby The urging force is released from the friction plate to disconnect the power transmission.

ところで、レリーズフォークは車体等の固定側に通常配置されているが、クラッチカバーはエンジンのフライホイール等に取り付けられてそれと一体的に回転するようになっている。従って、クラッチカバーのダイヤフラムスプリングをレリーズフォークが直に押圧するとなると、当接部の摩耗を招来することとなる。そこで、ダイヤフラムスプリングに当接して一体的に回転する回転輪と、レリーズフォークからの入力を受けるようになっている固定輪とからなるクラッチレリーズ軸受を、ダイヤフラムスプリングとレリーズフォークとの間に設けている（特許文献１参照）。
実開昭５７−１５０６２８号公報 By the way, the release fork is usually arranged on the fixed side of the vehicle body or the like, but the clutch cover is attached to a flywheel or the like of the engine and rotates integrally therewith. Therefore, when the release fork directly presses the diaphragm spring of the clutch cover, wear of the contact portion is caused. Therefore, a clutch release bearing is provided between the diaphragm spring and the release fork. The clutch release bearing is composed of a rotating wheel that contacts the diaphragm spring and rotates integrally and a fixed wheel that receives input from the release fork. (See Patent Document 1).
Japanese Utility Model Publication No. 57-150628

ここで、特許文献１に開示されたクラッチレリーズ軸受においては、リア側に非接触型のシールを設けている。かかるクラッチレリーズ軸受において、よりシール性能を高めたいという要求がある。シール性能を高めるために、接触型のシール部材を組み込むことが考えられる。ところが、半径方向内方に延在する外輪フランジ部を外輪に形成していると、フロント側にシール部材を設ける場合、外輪フランジ部側からシール部材を組み込めないので、反対側から組み込む必要がある。かかる場合、ボールの軌道面を横断しながら長い距離を移動して組み込むことになるため、どのようにしてシール部材を組み込むかが問題となる。例えば外輪内径と同径のシール部材を圧入しようとすると、軌道面を横切る際にシール部材が傾いてしまい、適切な位置への取り付けが困難となるという問題がある。   Here, in the clutch release bearing disclosed in Patent Document 1, a non-contact type seal is provided on the rear side. In such a clutch release bearing, there is a demand to further improve the sealing performance. In order to improve the sealing performance, it is conceivable to incorporate a contact type sealing member. However, when the outer ring flange portion extending radially inward is formed on the outer ring, when the seal member is provided on the front side, the seal member cannot be incorporated from the outer ring flange portion side, so it is necessary to incorporate from the opposite side. . In such a case, since a long distance is moved and incorporated while traversing the raceway surface of the ball, how to incorporate the seal member becomes a problem. For example, if a seal member having the same diameter as the inner diameter of the outer ring is to be press-fitted, the seal member is inclined when crossing the raceway surface, which makes it difficult to attach to an appropriate position.

本発明は、かかる従来技術の問題点に鑑みてなされたものであり、シール性能を確保しながらも、適切な組み付けを行えるクラッチレリーズ軸受を提供することを目的とする。   The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a clutch release bearing that can be properly assembled while ensuring sealing performance.

上記目的を達成すべく、本発明のクラッチレリーズ軸受は、
互いに同心的に配置されかつ相対回転する内輪及び外輪と、両輪間を転動する転動体と、前記転動体を保持する保持器と、接触型のシール部材とを含み、前記内輪が入力部材より力を受け、回転する前記外輪がクラッチ装置の回転部材に当接するようになっているクラッチレリーズ軸受において、
前記外輪は、半径方向内方に延在する外輪フランジ部と、前記外輪の内周面に形成された前記転動体が転動する軌道面とを有しており、
前記シール部材は、心金とそれに付着されたゴムもしくは樹脂部とよりなり、前記心金は軸線と同軸に軸線方向に延在し且つ少なくとも内周面が露出した短円筒部を有することを特徴とする。 In order to achieve the above object, the clutch release bearing of the present invention is
An inner ring and an outer ring that are arranged concentrically and rotate relative to each other; a rolling element that rolls between the two rings; a cage that holds the rolling element; and a contact-type seal member, wherein the inner ring is formed by an input member In the clutch release bearing that receives the force and rotates the outer ring so as to come into contact with the rotating member of the clutch device.
The outer ring has an outer ring flange portion extending radially inward, and a raceway surface on which the rolling elements formed on the inner peripheral surface of the outer ring roll,
The seal member is composed of a mandrel and a rubber or resin part attached thereto, and the mandrel has a short cylindrical part that extends in the axial direction coaxially with the axis and at least the inner peripheral surface is exposed. And

本発明のクラッチレリーズ軸受によれば、前記外輪は、半径方向内方に延在する外輪フランジ部と、前記外輪の内周面に形成された前記転動体が転動する軌道面とを有しており、前記シール部材は、心金とそれに付着されたゴムもしくは樹脂部とよりなり、前記心金は軸線と同軸に軸線方向に延在し且つ少なくとも内周面が露出した短円筒部を有するので、かかる短円筒部の内周にシール部材押し込み治具を係合させれば、その治具を用いて前記シール部材のセンタリング動作を行うことができ、前記シール部材の倒れを抑えて精度の良い組付けを行える。   According to the clutch release bearing of the present invention, the outer ring has an outer ring flange portion extending radially inward, and a raceway surface on which the rolling elements formed on the inner peripheral surface of the outer ring roll. The seal member includes a mandrel and a rubber or resin portion attached to the mandrel, and the mandrel has a short cylindrical portion extending in the axial direction coaxially with the axis and having at least an inner peripheral surface exposed. Therefore, if a seal member pushing jig is engaged with the inner periphery of the short cylindrical portion, the centering operation of the seal member can be performed using the jig, and the tilting of the seal member is suppressed and the accuracy is reduced. Good assembly is possible.

このように、前記シール部材の短円筒部の内周に係合する係合部を有するシール部材押し込み治具があれば、前記シール部材の組付けを行えば、精度の良い組付けを行える。更に、組み付け時において、かかるシール部材押し込み治具を、前記シール部材の心金の全周に押し当てれば、前記シール部材の変形を抑制することもできる。   Thus, if there is a seal member pushing jig having an engaging portion that engages with the inner periphery of the short cylindrical portion of the seal member, the assembly can be performed with high accuracy by assembling the seal member. Furthermore, when the seal member pushing jig is pressed against the entire circumference of the mandrel of the seal member during assembly, deformation of the seal member can be suppressed.

以下、本発明の実施の形態を図面を参照して以下に詳細に説明する。図１は、本実施の形態にかかるクラッチレリーズ軸受の断面図である。図２は、本実施の形態におけるシール部材の組み付け工程を示す断面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view of a clutch release bearing according to the present embodiment. FIG. 2 is a cross-sectional view showing the assembly process of the seal member in the present embodiment.

図１において、本実施の形態にかかるクラッチレリーズ軸受１０は、外輪１１と、内輪１２と、外輪１１と内輪１２との間に配置された複数の転動体であるボール１３と、ボール１３を保持する保持器１４と、外輪１１に取り付けられたシール部材１６とを有している。図示していないが、クラッチレリーズ軸受１０の内輪１２は、レリーズフォーク（入力部材）に押されてガイド軸に沿って移動し、それにより外輪フランジ部１１ｂがクラッチ部材のダイヤフラムスプリング（回転部材）に当接するようになっている。   In FIG. 1, a clutch release bearing 10 according to the present embodiment holds an outer ring 11, an inner ring 12, a plurality of rolling elements 13 disposed between the outer ring 11 and the inner ring 12, and the ball 13. And a seal member 16 attached to the outer ring 11. Although not shown, the inner ring 12 of the clutch release bearing 10 is pushed by the release fork (input member) and moves along the guide shaft, whereby the outer ring flange portion 11b becomes a diaphragm spring (rotating member) of the clutch member. It comes to contact.

外輪１１は、内周に軌道面１１ｄを形成した円筒状の外輪本体１１ａと、外輪本体１１ａの一端（図で左端）から半径方向に延在する外輪フランジ部１１ｂとを有している。   The outer ring 11 includes a cylindrical outer ring main body 11a having a raceway surface 11d formed on the inner periphery, and an outer ring flange portion 11b extending in a radial direction from one end (the left end in the drawing) of the outer ring main body 11a.

一方、内輪１２は、外周に軌道面を形成した円筒状の内輪本体１２ａと、内輪本体１２ａの一端（図で左端）から半径方向に延在する内輪フランジ部１２ｂと、内輪本体１２ａの外周面に形成された軌道面１２ｃとを有している。外輪フランジ部１１ｂと内輪フランジ部１２ｂとは、それらの間に所定のスキマを有して対峙している。   On the other hand, the inner ring 12 includes a cylindrical inner ring main body 12a having a raceway surface on the outer periphery, an inner ring flange portion 12b extending radially from one end (the left end in the figure) of the inner ring main body 12a, and an outer peripheral surface of the inner ring main body 12a. And a raceway surface 12c formed on the surface. The outer ring flange portion 11b and the inner ring flange portion 12b are opposed to each other with a predetermined clearance therebetween.

軌道面１１ｄに対してフロント側（図１で左側）において外輪１１の内周面に取り付けられたシール部材１６は、略円盤状の心金１６ａと、心金１６ａの内縁から延在するゴム製のリップ部１６ｂとを有する。板材をプレスによって形成されると好ましい心金１６ａは、その外縁に、同軸に軸線方向に延在する短円筒部１６ｃを形成している。短円筒部１６ｃの外周には肉盛り部１６ｄが形成されている。短円筒部１６ｃの内周面は露出した状態となっている。リップ部１６ｂと肉盛り部１６ｄはゴムもしくは樹脂から形成されており、従ってゴムもしくは樹脂部を形成する。   A seal member 16 attached to the inner peripheral surface of the outer ring 11 on the front side (left side in FIG. 1) with respect to the raceway surface 11d is a substantially disc-shaped mandrel 16a and a rubber member extending from the inner edge of the mandrel 16a. Lip portion 16b. When the plate material is formed by pressing, the preferable mandrel 16a has a short cylindrical portion 16c extending coaxially in the axial direction on the outer edge thereof. A built-up portion 16d is formed on the outer periphery of the short cylindrical portion 16c. The inner peripheral surface of the short cylindrical portion 16c is exposed. The lip portion 16b and the built-up portion 16d are made of rubber or resin, and thus form a rubber or resin portion.

尚、軌道面１１ｄに対してリヤ側（図１で右側）における外輪１１と内輪１２との間は、開放した状態に維持されているが、ここにシール部材１６と同様の接触式シール部材又は非接触式のシール部材を設けても良い。   The outer ring 11 and the inner ring 12 on the rear side (right side in FIG. 1) with respect to the raceway surface 11d are maintained in an open state. Here, a contact-type seal member similar to the seal member 16 or A non-contact seal member may be provided.

次に、本実施の形態にかかるクラッチレリーズ軸受の組み付け方法について説明する。まず、鍛造などによって外輪１１を形成し、機械加工で、溝１１ｃ及び軌道面１１ｄを形成する。形成した外輪１１に対して、予め形成したシール部材１６を挿入する。   Next, a method for assembling the clutch release bearing according to the present embodiment will be described. First, the outer ring 11 is formed by forging or the like, and the groove 11c and the raceway surface 11d are formed by machining. A previously formed seal member 16 is inserted into the formed outer ring 11.

挿入にあたって、図２に示すように、シール部材押し込み治具１７を用いる。シール部材押し込み治具１７は、円筒形状を有しており、先端に同軸の縮径部１７ａを形成している。縮径部１７ａの外径は、シール部材１６の短円筒部１６ｃの内径にほぼ等しくなっている。   For insertion, a seal member pushing jig 17 is used as shown in FIG. The seal member pushing jig 17 has a cylindrical shape, and a coaxial reduced diameter portion 17a is formed at the tip. The outer diameter of the reduced diameter portion 17 a is substantially equal to the inner diameter of the short cylindrical portion 16 c of the seal member 16.

ここで、縮径部１７ａをシール部材１６の短円筒部１６ｃの内周に嵌合させれば、組み付け時におけるシール部材１６の不用意な脱落を防止できる。更に、外輪１１とシール部材押し込み治具１７とを同軸に配置すれば、シール部材１６も同軸となる。かかる状態でシール押し込み治具１７を外輪１１に対して相対移動させれば、シール押し込み治具１７の端面又は縮径部１７ａの段部によって全周を押されたシール部材１６は、変形を抑制され安定した状態で軌道面１１ｄを横切って、シール組み付け用の溝１１ｃに肉盛り部１６ｄが密着し、それにより精度の良い組付けが実現する。   Here, if the reduced diameter portion 17a is fitted to the inner periphery of the short cylindrical portion 16c of the seal member 16, the seal member 16 can be prevented from being accidentally dropped during assembly. Furthermore, if the outer ring 11 and the seal member pushing jig 17 are disposed coaxially, the seal member 16 is also coaxial. If the seal pushing jig 17 is moved relative to the outer ring 11 in such a state, the seal member 16 whose entire circumference is pushed by the end face of the seal pushing jig 17 or the stepped portion of the reduced diameter portion 17a suppresses deformation. In addition, the built-up portion 16d is brought into close contact with the groove 11c for assembling the seal across the raceway surface 11d in a stable state, thereby realizing a highly accurate assembling.

以上、本発明を実施例を参照して説明してきたが、本発明は上記実施例に限定して解釈されるべきではなく、適宜変更・改良が可能であることはもちろんである。   The present invention has been described above with reference to the embodiments. However, the present invention should not be construed as being limited to the above-described embodiments, and can be changed or improved as appropriate.
