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に関する。   The present invention relates to a clutch release bearing 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 normally 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、非接触型のシールを設けているが、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、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. However, in such a clutch release bearing, there is a demand for further improving the sealing performance. In order to improve the sealing performance, it is conceivable to incorporate a contact type sealing member. However, if the outer ring flange portion extending radially inward is formed on the outer ring, the seal member cannot be assembled from the outer ring flange portion side, so it is necessary to incorporate it from the opposite side. In such a case, since it is 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、前記外輪フランジ部と前記転動面との間に挿入された後、外径を拡大されることにより前記外輪内周に取り付けられてい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 wheels; a cage that holds the rolling element; and a contact-type seal member, wherein the inner ring In the clutch release bearing that receives the force and the outer ring that rotates is brought 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 attached to the inner periphery of the outer ring by being expanded between outer diameters after being inserted between the outer ring flange portion and the rolling surface.

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、前記外輪フランジ部と前記転動面との間に挿入された後、外径を拡大されることにより前記外輪内周に取り付けられているので、前記シール部材を前記外輪内に挿入する際に、前記軌道面に触れることがなくスムーズな挿入を行うことができ、更に前記外輪フランジ部と前記転動面との間に挿入された後、外径を拡大されることにより前記外輪内周に取り付けられるので、確実な取り付けが可能となる。   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. And the seal member is inserted between the outer ring flange portion and the rolling surface and then attached to the inner periphery of the outer ring by enlarging the outer diameter. When inserted into the outer ring, smooth insertion can be performed without touching the raceway surface, and the outer diameter is enlarged after being inserted between the outer ring flange portion and the rolling surface. Since it is attached to the inner periphery of the outer ring, reliable attachment is possible.

前記シール部材は、心金と、前記心金から延在するリップ部とを有し、前記心金をカシメることにより外径を拡大させていると好ましい。   The sealing member preferably includes a mandrel and a lip portion extending from the mandrel, and the outer diameter is increased by caulking the mandrel.

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に取り付けられた第１のシール部材１５及び第２のシール部材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 first seal member 15 and a second 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に対してリヤ側（図１で右側）において外輪１１の内周面に取り付けられた第１のシール部材１５は、略円盤状の心金１５ａと、心金１５ａから延在する樹脂製のリップ部１５ｂとを有する。第１のシール部材１５の外周面は、図１で右端（外輪フランジ部１１ｂに対し軌道面１１ｄを挟んで反対側）の内周面に形成されたシール組付用の溝１１ｆに嵌合し、心金１５ａの内縁から延在するリップ部１５ｂを、内輪本体１２ａの外周面に当接させている。   The first seal member 15 attached to the inner peripheral surface of the outer ring 11 on the rear side (right side in FIG. 1) with respect to the raceway surface 11d is a substantially disk-shaped mandrel 15a and a resin extending from the mandrel 15a. And a lip portion 15b. The outer peripheral surface of the first seal member 15 is fitted in a seal assembling groove 11f formed on the inner peripheral surface at the right end (opposite side of the outer ring flange portion 11b across the raceway surface 11d) in FIG. The lip portion 15b extending from the inner edge of the mandrel 15a is brought into contact with the outer peripheral surface of the inner ring main body 12a.

一方、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第２のシール部材１６は、略円盤状の心金１６ａと、心金１６ａから延在する樹脂製のリップ部１６ｂとを有する。心金１６ａの外縁は、後述するようにカシメられて、外輪フランジ部１１ｂに隣接する内周面に形成されたシール組付用の溝１１ｃに嵌合し、心金１６ａの内縁から延在するリップ部１６ｂを、内輪フランジ部１２ｂの側面に当接させている。   On the other hand, the second 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 extends from the substantially disc-shaped mandrel 16a and the mandrel 16a. And a resin-made lip portion 16b. The outer edge of the mandrel 16a is crimped as will be described later, fits into a seal assembling groove 11c formed on the inner peripheral surface adjacent to the outer ring flange portion 11b, and extends from the inner edge of the mandrel 16a. The lip portion 16b is in contact with the side surface of the inner ring flange portion 12b.

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、１１ｆ及び軌道面１１ｄを形成する。この時点で、予め第２のシール部材１６を形成しておくが、かかる状態では図２（ａ）に示すように、薄板状の心金１６ａの外縁に軸線方向に延在するシール円筒部１６ｃがプレスで形成され、また円筒部１６ｃの先端を半径方向内側に丸めた鈎部１６ｄがプレスで形成されている。   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 grooves 11c and 11f and the raceway surface 11d are formed by machining. At this point, the second seal member 16 is formed in advance. In this state, as shown in FIG. 2A, the seal cylindrical portion 16c extending in the axial direction on the outer edge of the thin plate-shaped mandrel 16a. Is formed by pressing, and a flange portion 16d in which the tip of the cylindrical portion 16c is rounded inward in the radial direction is formed by pressing.

ここで、第２のシール部材１６を外輪１１内に挿入し、外輪フランジ部１１ｂの内側面に当接させた後、外輪本体１１ａの内径にほぼ等しい外径の円筒型Ｍを第２のシール部材１６に対して押しつける。円筒型Ｍは、押しつけ側先端に、先にゆくにつれ外径が縮小するテーパ面Ｍａと、テーパ面Ｍａの末端に形成された段部Ｍｂとを有している（図２（ｂ）参照）。   Here, after the second seal member 16 is inserted into the outer ring 11 and brought into contact with the inner side surface of the outer ring flange portion 11b, the cylindrical mold M having an outer diameter substantially equal to the inner diameter of the outer ring main body 11a is second sealed. Press against the member 16. The cylindrical mold M has a tapered surface Ma whose outer diameter is reduced as it goes first, and a stepped portion Mb formed at the end of the tapered surface Ma at the distal end of the pressing side (see FIG. 2B). .

円筒型Ｍは、上述のような形状を有するので、図２（ｂ）に示すように第２のシール部材１６に対して押しつけてゆくと、その段部Ｍｂに鈎部１６ｄの先端が引っかかり、その状態でテーパ面Ｍａが鈎部１６ｄを半径方向外方に押し広げてゆくので、シール円筒部１６ｃの軸線方向長は徐々に短くなると共に、心金１６ａの外径が広がり、最終的には図２（ｃ）に示すように、外輪１１の溝１１ｃ内にシール円筒部１６ｃと鈎部１６ｄとが密着するように塑性変形する。これをカシメという。   Since the cylindrical type M has the shape as described above, when it is pressed against the second seal member 16 as shown in FIG. 2B, the tip of the flange portion 16d is caught on the stepped portion Mb. In this state, the taper surface Ma pushes the flange portion 16d outward in the radial direction, so that the axial length of the seal cylindrical portion 16c gradually decreases and the outer diameter of the mandrel 16a widens. As shown in FIG. 2C, plastic deformation is performed so that the seal cylindrical portion 16c and the flange portion 16d are in close contact with each other in the groove 11c of the outer ring 11. This is called caulking.

円筒型Ｍを抜き出した後、外輪１１に、ボール１３，保持器１４，内輪１２を組み付けた後、最後に第１のシール部材１５を組み込むことで、図１に示すクラッチレリーズ軸受１０が完成する。   After extracting the cylindrical mold M, the ball 13, the cage 14, and the inner ring 12 are assembled to the outer ring 11, and the first seal member 15 is finally assembled, whereby the clutch release bearing 10 shown in FIG. 1 is completed. .

本実施の形態のクラッチレリーズ軸受１０によれば、リップ部１５ｂ、１６ｂがそれぞれ内輪１２に接触する接触型であるシール部材１５、１６を有することから、高い密封性能を得ることができる。又、第２のシール部材１６を外輪１１内に挿入する際に、軌道面１１ｄに触れることがなくスムーズな挿入を行うことができ、更に外輪フランジ部１１ｂに密着するように挿入された後、心金１６ａの外径を拡大されることにより外輪１１の内周の溝１１ｃに取り付けられるので、確実な取り付けが可能となる。   According to the clutch release bearing 10 of the present embodiment, since the lip portions 15b and 16b have the contact members 15 and 16 that are in contact with the inner ring 12, high sealing performance can be obtained. Further, when the second seal member 16 is inserted into the outer ring 11, the second seal member 16 can be smoothly inserted without touching the raceway surface 11d, and further inserted into close contact with the outer ring flange portion 11b. Since the outer diameter of the mandrel 16a is enlarged, the mandrel 16a is attached to the inner circumferential groove 11c of the outer ring 11, so that reliable attachment is possible.

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.
