Description

本発明は、車両に適用されるクラッチ装置に関する。 The present invention relates to a clutch device applied to a vehicle.

従来、一対の回転部材間を断続する断続機構を作動させる電磁石を備えたクラッチ装置としては、例えば、一側の回転部材であるデフケースと他側の回転部材である一方のサイドギヤとの間に設けられた断続機構としてのドッグクラッチと、ドッグクラッチを作動させる電磁式アクチュエータとを備えたものが知られている（例えば、特許文献１参照）。 Conventionally, as a clutch device including an electromagnet that operates an interrupting mechanism that interrupts between a pair of rotating members, for example, provided between a differential case that is a rotating member on one side and one side gear that is a rotating member on the other side. There has been known one provided with a dog clutch as an interrupted mechanism and an electromagnetic actuator for operating the dog clutch (for example, see Patent Document 1).

このクラッチ装置では、デフケースに対して電磁石としての電磁ソレノイドと可動部材としてのプランジャとをそれぞれ径方向に支持させており、電磁ソレノイドの背面側に電磁ソレノイドと当接する複数のプレートをデフケースにボルト止めすることによって電磁ソレノイドをデフケースに対して軸方向に位置決めさせている。 In this clutch device, an electromagnetic solenoid as an electromagnet and a plunger as a movable member are respectively supported in the radial direction with respect to the differential case, and a plurality of plates contacting the electromagnetic solenoid are bolted to the differential case on the back side of the electromagnetic solenoid. By doing so, the electromagnetic solenoid is positioned in the axial direction with respect to the differential case.

しかしながら、上記のようなクラッチ装置では、電磁石の軸方向移動を規制するために複数のプレートと、１つのプレートを固定するために２つのボルトとを用いているが、電磁石の軸方向移動の規制に関する部品点数が多く、組付けの作業性が低下していた。 However, the clutch device as described above uses a plurality of plates for restricting the axial movement of the electromagnet and two bolts for fixing one plate. As a result, the assembly workability has been reduced.

これに対して、電磁石の軸方向移動を規制する複数のプレートに換えて、非磁性体のスナップリングをデフケースに組付けたクラッチ装置や、磁性体を環状に形成させた相殺リングをデフケースにボルト止めさせたクラッチ装置が知られている（例えば、特許文献２参照）。 On the other hand, instead of a plurality of plates that restrict the axial movement of the electromagnet, a clutch device in which a non-magnetic snap ring is assembled to the differential case, or a counter ring having a magnetic material formed in an annular shape is bolted to the differential case. A clutch device that is stopped is known (see, for example, Patent Document 2).

このようなクラッチ装置では、スナップリングや環状の相殺リングを用いることによって、複数のプレートを用いる必要がなく、部品点数を削減することができる。加えて、スナップリングをデフケースに組付けることによって、プレートを固定するボルトも用いる必要がなく、さらに部品点数を削減することができる。 In such a clutch device, it is not necessary to use a plurality of plates by using a snap ring or an annular canceling ring, and the number of parts can be reduced. In addition, by attaching the snap ring to the differential case, it is not necessary to use bolts for fixing the plate, and the number of parts can be further reduced.

A locking means 207 is provided which is provided integrally with the member locking portion 203 and has an electromagnet locking portion 205 which contacts the end face of the electromagnet 11 and locks the movement of the electromagnet 11 in the axial direction. . In addition, although the same code | symbol is described to the structure same as 1st Embodiment, description is abbreviate | omitted, but since it is the same structure as 1st Embodiment, a structure and functional description refer to 1st Embodiment. Although omitted, the obtained effects are the same.

図７，図８に示すように、係止手段２０７は、ステンレス材などの非磁性体からなり、ワッシャなどのように環状に形成されたプレート部材２０８を含み、このプレート部材２０８は、可動部材係止部２０３と、電磁石係止部２０５とを備えている。可動部材係止部２０３は、環状に形成された部分の内径側に設けられ、リング部材３１の押圧部３３が形成された側とは反対側の軸方向端面と当接される当接面が設けられている。この可動部材係止部２０３は、デフケース３のボス部３０９の外周に挿入される。この可動部材係止部２０３の外径側には、電磁石係止部２０５が一体的に設けられている。 As shown in FIGS. 7 and 8, the locking means 207 includes a plate member 208 made of a nonmagnetic material such as stainless steel and formed in an annular shape such as a washer. The plate member 208 is a movable member. A locking portion 203 and an electromagnet locking portion 205 are provided. The movable member locking portion 203 is provided on the inner diameter side of the annular portion, and has a contact surface that is in contact with the axial end surface of the ring member 31 opposite to the side on which the pressing portion 33 is formed. Is provided. The movable member locking portion 203 is inserted into the outer periphery of the boss portion 309 of the differential case 3. An electromagnet locking portion 205 is integrally provided on the outer diameter side of the movable member locking portion 203.

電磁石係止部２０５は、環状に形成された部分の外径側に設けられ、詳細には可動部材係止部２０３の外径側の周方向に可動部材係止部２０３と連続する一部材で形成され、コア３９の端面と当接される当接面が設けられている。この係止手段２０７は、スナップリング機能を有する固定部材２０９を含み、この固定部材２０９によって軸方向位置が位置決めされている。 The electromagnet locking portion 205 is provided on the outer diameter side of the annular portion, and specifically, is a single member that is continuous with the movable member locking portion 203 in the circumferential direction on the outer diameter side of the movable member locking portion 203. An abutment surface that is formed and abuts against the end surface of the core 39 is provided. The locking means 207 includes a fixing member 209 having a snap ring function, and the axial position is positioned by the fixing member 209.

固定部材２０９は、Ｃ型クリップなどのように一部が切り欠かれた環状に形成され、係止手段２０７を軸方向に挟んで可動部材９及び電磁石１１と対向配置され、デフケース３のボス部３０９の外周に形成された溝部に固定される。この固定部材２０９と可動部材９及び電磁石１１との間に配置される係止手段２０７は、各部材に対して軸方向に適度な隙間（例えば、0.5〜1.5mm程度）が設定されている。このため、デフケース３が回転した場合には、係止手段２０７が多少の連れ回りをして部材間の片当たりやカジリを防止するように機能している。また、プレート部材２０８には切り欠きや孔を有する開口２１０が設けられており、表裏面を貫通することで電磁石１１との当接面にオイルなどによる貼り付きを防止することができる。また、固定部材２０９によって係止手段２０７の位置決めを行うことにより、係止手段２０７の可動部材係止部２０３と可動部材９の端面との当接、電磁石係止部２０５と電磁石１１の端面との当接によって、可動部材９及び電磁石１１の軸方向移動が係止されると共に、可動部材９及び電磁石１１のデフケース３に対する軸方向位置が位置決めされる。つまり、係止手段２０７の一部材を可動部材９と電磁石１１とに当接させることにより、可動部材９及び電磁石１１の軸方向位置を位置決めすることができる。 The fixed member 209 is formed in an annular shape with a part cut away, such as a C-shaped clip, and is disposed opposite the movable member 9 and the electromagnet 11 with the locking means 207 sandwiched in the axial direction, and the boss portion of the differential case 3 It is fixed to the groove part formed in the outer periphery of 309. The locking means 207 disposed between the fixed member 209 and the movable member 9 and the electromagnet 11 has an appropriate gap (for example, about 0.5 to 1.5 mm) in the axial direction with respect to each member. For this reason, when the differential case 3 is rotated, the locking means 207 functions so as to prevent some contact between members and galling. Further, the plate member 208 is provided with an opening 210 having a notch or a hole, and by sticking through the front and back surfaces, it is possible to prevent sticking with oil or the like on the contact surface with the electromagnet 11. Further, by positioning the locking means 207 by the fixed member 209, the movable member locking portion 203 of the locking means 207 contacts the end surface of the movable member 9, and the electromagnet locking portion 205 and the end surface of the electromagnet 11 are contacted. As a result, the movement of the movable member 9 and the electromagnet 11 in the axial direction is locked, and the axial positions of the movable member 9 and the electromagnet 11 with respect to the differential case 3 are positioned. That is, the axial position of the movable member 9 and the electromagnet 11 can be positioned by bringing one member of the locking means 207 into contact with the movable member 9 and the electromagnet 11.

このようなクラッチ装置２０１では、係止手段２０７の可動部材９の軸方向一側への移動を係止する可動部材係止部２０３と電磁石１１の軸方向一側への移動を係止する電磁石係止部２０５とが一体的に設けられているので、一部材で可動部材９と電磁石１１とを同時に係止することができ、部品点数を削減することができる。加えて、一部材で可動部材９と電磁石１１とを同時に係止することができるので、可動部材９と電磁石１１の位置決めの構造を簡素化することができる。 In such a clutch device 201, the movable member locking portion 203 that locks the movement of the movable member 9 in the axial direction of the locking member 207 and the electromagnet that locks the movement of the electromagnet 11 in the axial direction. Since the locking portion 205 is integrally provided, the movable member 9 and the electromagnet 11 can be locked simultaneously with a single member, and the number of parts can be reduced. In addition, since the movable member 9 and the electromagnet 11 can be simultaneously locked with one member, the positioning structure of the movable member 9 and the electromagnet 11 can be simplified.

また、係止手段２０７がワッシャなどのように環状に形成されているので、係止手段２０７の形状を複雑化する必要がなく、可動部材９と電磁石１１の位置決めの構造をさらに簡素化することができる。 Further, since the locking means 207 is formed in an annular shape such as a washer, the shape of the locking means 207 does not need to be complicated, and the structure for positioning the movable member 9 and the electromagnet 11 is further simplified. Can do.

This is applied to a so-called differential lock mechanism that connects the side gear 5 to the other side gear 5. However, according to other differential devices, the differential case 3 is driven as a double case that can be relatively rotated on the inner and outer peripheral sides. It can be similarly used for a so-called free running differential mechanism that interrupts the force and transmits the driving force from the outer peripheral differential case to the inner peripheral differential case having a differential mechanism. Furthermore, the present invention is not limited to this, and any mechanism may be used to form the pair of rotating members, such as a structure in which the power transmission of the transmission mechanism is interrupted by interrupting a pair of relatively rotatable rotating members.
