Description

本発明は、互いに平行に配置されかつ大径側と小径側とが軸方向に逆になるように配置された1対の円錐形状の摩擦車と、これら両摩擦車の対向する傾斜面に挟持されるリングとを有し、前記リングを軸方向に移動して無段変速する円錐摩擦リング式無段変速装置に係り、詳しくは前記リングを軸方向に移動する変速操作装置(手段)の潤滑に関する。   The present invention includes a pair of conical friction wheels arranged parallel to each other and arranged so that the large diameter side and the small diameter side are opposite in the axial direction, and sandwiched between the inclined surfaces facing each other. A conical friction ring-type continuously variable transmission that moves continuously in the axial direction by moving the ring in the axial direction, and more specifically, lubrication of a speed change operation device (means) that moves the ring in the axial direction About.

従来、入力側となる円錐形状の摩擦車と、出力側となる円錐形状の摩擦車と、両摩擦車の対向する傾斜面に挟持される金属製のリングと、を有し、上記両摩擦車の軸線を平行にかつその大径部と小径部とが軸方向に逆になるように配置し、前記リングを軸方向に移動することにより無段に変速する円錐摩擦リング式無段変速装置(コーンリング式CVTという)が知られている。   Conventionally, a conical friction wheel on the input side, a conical friction wheel on the output side, and a metal ring sandwiched between inclined surfaces facing both friction wheels, the two friction wheels A conical friction ring type continuously variable transmission (hereinafter referred to as a “conical friction ring-type continuously variable transmission”) that is arranged in parallel so that the large-diameter portion and the small-diameter portion thereof are opposite in the axial direction, and the ring is moved in the axial direction. Corn ring type CVT) is known.

上記コーンリング式CVTの変速操作装置として下記特許文献1及び特許文献2に記載されたものがある。特許文献1に記載の変速操作装置は、上記リングを挟んで該リングを回転自在かつ軸方向に一体に移動し得るフォークと、該フォークを移動方向にピンを介して揺動自在に支持する送りナットと、該送りナットを前記移動方向に送る送りねじ軸と、を備え、該送りねじ軸により送りナットを軸方向に移動することにより、前記フォークをピンを中心に移動方向に傾かせて、前記入力側摩擦車と出力側摩擦車との間で挟持されて回転しているリングをその回転軸に対して傾ける。これにより、リングは、摩擦車に対してヘリカルラインとなり、軸方向に移動して変速操作される。   As the cone ring type CVT gear shifting operation device, there are those described in Patent Document 1 and Patent Document 2 below. A speed change operation device described in Patent Document 1 includes a fork that can rotate and integrally move in the axial direction with the ring interposed therebetween, and a feed that supports the fork so as to swing in a moving direction via a pin. A nut and a feed screw shaft that feeds the feed nut in the movement direction, and by moving the feed nut in the axial direction by the feed screw shaft, the fork is tilted in the movement direction around the pin, A ring that is sandwiched and rotated between the input side friction wheel and the output side friction wheel is tilted with respect to the rotation axis. As a result, the ring becomes a helical line with respect to the friction wheel, and moves in the axial direction to be shifted.

引用文献2に記載の変速操作装置は、2本の平行軸により軸方向移動自在に支持されたフレームに回転自在に前記リングを支持すると共に、該フレームを前記両摩擦車の軸線を含む平面内でかつ上記軸線に直交する回転軸を中心に回転自在に支持する。上記フレームを上記回転軸を中心に傾けることにより、前記リングは、摩擦車に対してヘリカルラインとなり、軸方向に移動して変速操作される。   The speed change operation device described in the cited document 2 supports the ring rotatably on a frame supported so as to be axially movable by two parallel shafts, and supports the frame in a plane including the axes of the two friction wheels. And is supported rotatably about a rotation axis orthogonal to the axis. By tilting the frame about the rotation shaft, the ring becomes a helical line with respect to the friction wheel, and moves in the axial direction to be shifted.

Specifically, an axial force applying means (not shown) including an inclined cam having a ball interposed between the output side friction wheel 23 and the continuously variable transmission output shaft 24 is formed on a surface opposed in the axial direction. Thus, a thrust force in the direction of arrow D corresponding to the transmission torque is generated in the output side friction wheel 23, and the ring 25 is large with the input side friction wheel 22 supported in a direction against the thrust force. A pinching pressure is generated.

ついで、上述したハイブリッド駆動装置1の作動について説明する。本ハイブリッド駆動装置1は、ケース11の第3の空間C側を内燃エンジンに結合され、かつ該エンジンの出力軸をクラッチを介して入力軸6に連動して用いられる。エンジンからの動力が伝達される入力軸6の回転は、スプラインSを介してコーンリング式無段変速装置3の入力側摩擦車22に伝達され、更にリング25を介して出力側摩擦車23に伝達される。   Next, the operation of the hybrid drive device 1 described above will be described. The hybrid drive device 1 is used in such a manner that the third space C side of the case 11 is coupled to an internal combustion engine, and the output shaft of the engine is linked to the input shaft 6 via a clutch. The rotation of the input shaft 6 to which power from the engine is transmitted is transmitted to the input side friction wheel 22 of the cone ring type continuously variable transmission 3 via the spline S, and further to the output side friction wheel 23 via the ring 25. Communicated.

この際、両摩擦車22,23とリング25との間は、出力側摩擦車23に作用する矢印D方向のスラスト力により大きな接触圧が作用し、かつ第1の空間Aはトラクション用オイルが充填されているので、上記両摩擦車とリングとの間には、該トラクション用オイルの油膜が介在した極圧状態となる。この状態では、トラクション用オイルは大きな剪断力を有するので、該油膜の剪断力により両摩擦車とリングとの間に動力伝達が行われる。これにより、金属同士の接触でありながら、摩擦車及びリングが摩耗することなく、所定のトルクを滑ることなく伝達し得、かつリング25を軸方向に滑らかに移動することにより、両摩擦車との接触位置を変更して無段に変速する。   At this time, a large contact pressure acts between the friction wheels 22, 23 and the ring 25 due to the thrust force in the direction of arrow D acting on the output-side friction wheel 23, and the traction oil is in the first space A. Since it is filled, an extreme pressure state in which an oil film of the traction oil is interposed between the two friction wheels and the ring. In this state, since the traction oil has a large shearing force, power is transmitted between the friction wheels and the ring by the shearing force of the oil film. Accordingly, the friction wheel and the ring can be transmitted without slipping while being in contact with each other, and the predetermined torque can be transmitted without slipping, and the ring 25 can be smoothly moved in the axial direction. The contact position is changed to change continuously.

該無段変速された出力側摩擦車23の回転は、その出力軸24、出力ギヤ44及びデフリングギヤ41を介してディファレンシャル装置5のデフケース33に伝達され、左右のアクスル軸39l,39rに動力分配されて、車輪(前輪)を駆動する。   The rotation of the continuously variable speed output side friction wheel 23 is transmitted to the differential case 33 of the differential device 5 via the output shaft 24, the output gear 44 and the differential ring gear 41, and the power is distributed to the left and right axle shafts 39l and 39r.

The rotation of the input shaft 6 is continuously variable via the cone ring type continuously variable transmission 3 and further transmitted to the differential device 5 via the output gear 44 and the diff ring gear 41 as described above. . The gear transmission 7 comprising the gears 16, 17, 19, 44, 41, 37, 40 is housed in a second space B filled with lubricating oil, and the lubricating oil is engaged when the gears are engaged. Smoothly transmits power. At this time, the differential ring gear 41 disposed at the lower position of the second space B is combined with the large-diameter gear to scoop up the lubricating oil and other gears (gears) 16, 17, 19 , 44 and the bearings 27, 30, 20, 21, 31, 48 are reliably and sufficiently supplied with lubricating oil.

上記エンジン及び電気モータの作動形態、即ちハイブリッド駆動装置1として作動形態は、必要に応じて各種採用可能である。一例として、車輌発進時、クラッチを切断すると共にエンジンを停止し、電気モータ2のトルクのみにより発進し、所定速度になると、エンジンを始動して、エンジン及び電気モータの動力により加速し、巡航速度になると、電気モータをフリー回転又は回生モードとして、エンジンのみにより走行する。減速、制動時は、電気モータを回生してバッテリを充電する。また、クラッチを発進クラッチとして使用し、エンジンの動力により、モータトルクをアシストとして用いつつ発進するように用いてもよい。   Various operation modes of the engine and the electric motor, that is, the operation mode of the hybrid drive device 1 can be adopted as necessary. As an example, when the vehicle starts, the clutch is disengaged and the engine is stopped, the engine is started only by the torque of the electric motor 2, and when the vehicle reaches a predetermined speed, the engine is started and accelerated by the power of the engine and the electric motor. Then, the electric motor is set to the free rotation or regenerative mode and travels only by the engine. During deceleration and braking, the electric motor is regenerated to charge the battery. Alternatively, the clutch may be used as a starting clutch, and may be used to start while using the motor torque as an assist by the power of the engine.

ついで、図2ないし図4に沿って、本発明に係る円錐摩擦リング式無段変速装置(コーンリング式CVT)3について説明する。該無段変速装置3は、前述したように、入力側摩擦車22、出力側摩擦車23及びリング25からなり、これら両摩擦車及びリングが鋼等の金属からなる。両摩擦車22,23は、その軸線l−l、n−n(図1参照)が水平方向にあって互いに平行になるように配置され、かつ傾斜面が直線からなる円錐形状からなり、対向する両傾斜面の間にリング25が挟持される。リング25は、両摩擦車のいずれか一方、具体的には入力側(第1の円錐形)摩擦車22を囲むように配置され、その周方向に垂直な面での断面が略々平行四辺形からなり、その回転面m−mは、軸線l−lに対して略々直交するように設定されている。   Next, a conical friction ring type continuously variable transmission (cone ring type CVT) 3 according to the present invention will be described with reference to FIGS. As described above, the continuously variable transmission 3 includes the input side friction wheel 22, the output side friction wheel 23, and the ring 25. Both the friction wheel and the ring are made of metal such as steel. The friction wheels 22 and 23 are arranged so that their axis lines l-n and n-n (see FIG. 1) are parallel to each other in parallel and have a conical shape whose inclined surface is a straight line. A ring 25 is sandwiched between the two inclined surfaces. The ring 25 is arranged so as to surround either one of the friction wheels, specifically, the input side (first conical) friction wheel 22, and a cross section in a plane perpendicular to the circumferential direction is substantially parallel to the four sides. It has a shape, and its rotation surface mm is set so as to be substantially orthogonal to the axis line l-1.

上記コーンリング式CVT3は、有底筒状の第1のケース部材9により一端側及びその全周側を覆われており、上記第1のケース部材9の開口側は隔壁12により蓋されて、第1の空間Aに油密状に収納されている。出力側(他方の円錐形)摩擦車23の軸23aが入力側(一方の円錐形)摩擦車22の軸22aより所定量上方に位置するように、両摩擦車は斜めに配置されており、入力側摩擦車22は、その上方、下方及び出力側摩擦車22と反対方向側方においてケース部材9との間に余裕をもって配置されている。上記入力側摩擦車22を囲んでいるリング25は、該入力側摩擦車とケース部材9との間の空間に配置されると共に、該リング25を軸方向に移動する変速操作手段(装置)60が配置されている。なお、図2において、ケース部材9の上方部分9Aは、電気モータ2が配置される部分、9Bは、ディファレンシャル装置5が配置される部分である。また、上記ケース部材9との間の上記入力側摩擦車22の下方空間Jはトラクション用オイルのオイル溜り59(オイルレベルを59aで表記)となっている。   The cone ring type CVT 3 is covered at one end side and the entire circumference thereof with a bottomed cylindrical first case member 9, and the opening side of the first case member 9 is covered with a partition wall 12. The first space A is stored in an oil-tight manner. The two friction wheels are arranged obliquely so that the shaft 23a of the output side (the other conical shape) friction wheel 23 is positioned a predetermined amount above the shaft 22a of the input side (the one conical shape) friction wheel 22. The input side friction wheel 22 is arranged with a margin between the input side friction wheel 22 and the case member 9 on the upper side, the lower side, and the side opposite to the output side friction wheel 22. A ring 25 surrounding the input side friction wheel 22 is disposed in a space between the input side friction wheel and the case member 9 and is a speed change operation means (device) 60 for moving the ring 25 in the axial direction. Is arranged. In FIG. 2, the upper portion 9A of the case member 9 is a portion where the electric motor 2 is disposed, and 9B is a portion where the differential device 5 is disposed. A space J below the input side friction wheel 22 between the case member 9 is an oil reservoir 59 (oil level is indicated by 59a) for traction oil.

前記変速操作手段60は、入力側摩擦車22の上方空間Fに配置された送りねじ軸61と、前記オイル溜り59となる下方空間Jに配置されたガイドレール62と、入力側摩擦車22の出力側摩擦車23反対面を囲むように側方空間Gに配置された移動部材63と、を有する。送りねじ軸61及びガイドレール62は前記入力側摩擦車22を挟んだ上下位置にあって互いに平行に配置されており、かつ両円錐形摩擦車22,23が対向する斜面に沿うように平行に配置されている。送りねじ軸61は、ケース部材9に回転自在に支持されていると共に、モータ等の変速駆動手段が連動されており、アクセルペダル等の運転者の意思及び車輌の走行状況に応じた制御部からの駆動信号により適宜回転駆動される。   The speed change operating means 60 includes a feed screw shaft 61 disposed in the upper space F of the input side friction wheel 22, a guide rail 62 disposed in the lower space J serving as the oil reservoir 59, and the input side friction wheel 22. And a moving member 63 disposed in the side space G so as to surround the opposite surface of the output side friction wheel 23. The feed screw shaft 61 and the guide rail 62 are arranged in a vertical position with the input side friction wheel 22 in between, and are arranged in parallel to each other, and in parallel so that the two conical friction wheels 22 and 23 are along the opposing inclined surfaces. Has been placed. The feed screw shaft 61 is rotatably supported by the case member 9 and is linked with a speed change driving means such as a motor. From the control unit according to the driver's intention such as an accelerator pedal and the traveling state of the vehicle. The drive signal is appropriately rotated by the drive signal.

移動部材63は、前記送りねじ軸61及びガイドレール62に亘って軸方向移動自在に支持されており、その上部に送りねじ軸61に螺合するボールナット部65が固定されていると共に、その下部に前記ガイドレール62に軸方向移動自在に支持されるスライド部66が固定されている。そして、上記移動部材63におけるボールナット部65と反対面である内面側に上(第1の)支持部材67が設置されており、上記スライド部の反対側である内面画に下(第2の)支持部材69が設置されている。上記上支持部材67と下支持部材69とは、入力側及び出力側の両摩擦車22,23の軸線l−l,n−nを含む平面に対して、異なる側に配置されることになるが、両支持部材67,69は、それぞれ上記軸線平面から最も離れた位置にてリング25を支持するように配置されている。なお、上記リング25を変速操作する軸方向移動とは、互いに平行な上記送りねじ軸61及びガイドレール62に沿って移動部材63が移動する方向、即ちリングが接触する両摩擦車22,23の対向する斜面に沿う方向を意味し、両摩擦車の軸線とは異なる。   The moving member 63 is supported so as to be movable in the axial direction across the feed screw shaft 61 and the guide rail 62, and a ball nut portion 65 that is screwed to the feed screw shaft 61 is fixed to the upper portion of the moving member 63. A slide portion 66 supported by the guide rail 62 so as to be movable in the axial direction is fixed to the lower portion. An upper (first) support member 67 is installed on the inner surface side of the moving member 63 opposite to the ball nut portion 65, and the lower (second) support member 67 is placed on the inner surface image on the opposite side of the slide portion. ) A support member 69 is installed. The upper support member 67 and the lower support member 69 are disposed on different sides with respect to the plane including the axes ll and nn of the friction wheels 22 and 23 on the input side and the output side. However, both support members 67 and 69 are arranged so as to support the ring 25 at a position farthest from the axis plane. The axial movement for shifting the ring 25 is a direction in which the moving member 63 moves along the feed screw shaft 61 and the guide rail 62 that are parallel to each other, that is, the friction wheels 22 and 23 in contact with the rings. It means the direction along the opposing slope and is different from the axis of both friction wheels.

前記上支持部材67及び下支持部材69は、リング25を挟むように支持し得ると共に、移動部材63と一体に移動して、リング25を軸方向に移動するものであるが、上及び下支持部材67,69は、リング25が両摩擦車22,23との接触部に引込まれる回転方向上流側にあってはリング25を両面から支持して軸方向に規定するように(摘むように)連動するが、上記接触部から押出される回転方向下流側にあってはリング25の軸方向移動(振れ)を許容する構造からなる。従って、リング25は、摩擦車の正逆どちらの回転にあっても、その上流側に位置する上下いずれかの支持部材67又は69により摘むように支持され、移動部材63の移動又は停止に基づく位置に応じて位置決めされ、上下いずれか他方の支持部材69又は67は、その際の上記移動又は停止におけるリング25の振れを許容して、リング25は自律的に支持される。   The upper support member 67 and the lower support member 69 can support the ring 25 so as to sandwich the ring 25, and move integrally with the moving member 63 to move the ring 25 in the axial direction. The members 67 and 69 support the ring 25 from both sides when the ring 25 is on the upstream side in the rotational direction where the ring 25 is drawn into the contact portion with the two friction wheels 22 and 23 so as to be defined in the axial direction. Although interlocked, it has a structure that allows the axial movement (swing) of the ring 25 on the downstream side in the rotational direction pushed out from the contact portion. Accordingly, the ring 25 is supported so as to be picked by the upper or lower support member 67 or 69 located upstream of the friction wheel regardless of whether the friction wheel is rotating forward or backward, and the position based on the movement or stop of the moving member 63. Accordingly, either the upper or lower support member 69 or 67 allows the swing of the ring 25 in the above movement or stop at that time, and the ring 25 is autonomously supported.

なお、上下の支持部材67,69は、図3に示すように、同じ構成からなり、リング25の左右に配置される1対の作動部70,70を有するが、左右の作動部70,70の厚さ(径方向長さ)又は作用位置が異なるのは、リング25が摩擦車の軸線l−lに垂直な平面m−mになるように構成するため、断面を平行四辺形に形成したことに起因し、リング25の左右においてその中央部に支持力を作用するようにして、リングにモーメントが作用しないようにするためである。   As shown in FIG. 3, the upper and lower support members 67 and 69 have the same configuration and have a pair of operating portions 70 and 70 disposed on the left and right sides of the ring 25, but the left and right operating portions 70 and 70 are included. The thickness (radial length) or the working position of the ring is different because the ring 25 is configured to be a plane mm that is perpendicular to the axis 11 of the friction wheel, so that the cross section is formed in a parallelogram. This is because a supporting force is applied to the center of the ring 25 on the left and right sides so that no moment is applied to the ring.

また、リング25は、軸方向移動を規定する回転上流側の支持部材67又は69と両摩擦車との接触部とでその傾斜角(軸線に直交する傾斜角0も含む)が定まるが、上記支持部材は、接触部と最も離れた位置にてリングを支持するので、リングの傾斜角は安定して、正確な変速操作並びに一定速の速度維持操作を容易に行うことができ、かつ移動部材63の移動速度に応じたリングの傾斜角が容易かつ確実に設定でき、素速い応答速度での変速が可能となる。   In addition, the ring 25 has an inclination angle (including an inclination angle 0 perpendicular to the axis) determined by the contact portion between the support member 67 or 69 on the upstream side that defines the axial movement and the friction wheels. Since the support member supports the ring at a position farthest from the contact portion, the inclination angle of the ring is stable, an accurate speed change operation and a constant speed speed maintenance operation can be easily performed, and the moving member The inclination angle of the ring according to the moving speed of 63 can be set easily and reliably, and a shift with a quick response speed becomes possible.

前記移動部材63は、上端に位置するボールナット部65と下端に位置するスライド部66に亘って、入力側摩擦車22の外側に沿うように円弧状に延びる連結部63aを有しており、該連結部63aの内周面には、前記リング25を受入れるように、所定幅及び所定深さの凹溝71が形成されている。また、上記移動部材63の下端部先端63dにはオイルガイド72が固定されている。オイルガイド72は、断面コ字状でかつ所定角度の円弧状からなり、その凹部72aに上記リング25を受入れる板金部材からなる。該オイルガイド72の先端は、出力側摩擦車23と干渉しない範囲でリングと摩擦車との接触部に近づく位置にあって自由端となっており、上記リング25の外周に沿って延びている。なお、上記凹溝71及びオイルガイド72の凹部72aは、変速操作に際してリング25が傾動しても、該リングと干渉しない幅に設定されている。また、移動部材63は、その内周面にリング25を受入れる凹溝71を有するので、その分リング外径側に突出する寸法を小さくでき、コーンリング式CVT3のコンパクト性を向上し得る。   The moving member 63 has a connecting portion 63a extending in an arc shape along the outside of the input side friction wheel 22 over a ball nut portion 65 located at the upper end and a slide portion 66 located at the lower end, A concave groove 71 having a predetermined width and a predetermined depth is formed on the inner peripheral surface of the connecting portion 63a so as to receive the ring 25. An oil guide 72 is fixed to the tip 63d of the lower end of the moving member 63. The oil guide 72 has a U-shaped cross section and has an arc shape with a predetermined angle, and is made of a sheet metal member that receives the ring 25 in the recess 72a. The tip of the oil guide 72 is a free end at a position approaching the contact portion between the ring and the friction wheel within a range not interfering with the output side friction wheel 23, and extends along the outer periphery of the ring 25. . The concave groove 71 and the concave portion 72a of the oil guide 72 are set to a width that does not interfere with the ring 25 even when the ring 25 is tilted during a shifting operation. Moreover, since the moving member 63 has the recessed groove 71 which receives the ring 25 in the inner peripheral surface, the dimension which protrudes to the ring outer-diameter side can be made small, and the compactness of cone ring type CVT3 can be improved.

そして、前記変速操作手段60は、そのガイドレール62及びスライド部66がその軸方向(移動方向)全可動範囲に亘って前記オイル溜り59に浸っている。更に、下支持部材69も、移動部材63の軸方向(移動方向)全可動範囲に亘って上記オイル溜り59に浸っている。一方、移動部材63の上部に位置するボールナット部65及び送りねじ軸61は、その軸方向(移動方向)全可動範囲に亘ってオイルレベル59aの上方に位置している。更に、上支持部材67も、移動部材63の軸方向(移動方向)全可動範囲に亘ってオイルレベル59aの上方に位置して、オイル溜り59に浸ることはない。なお、車輌前進時におけるコーンリング式CVT3の正回転時、入力側摩擦車22は、図2の矢印K方向に回転し、上記リング25は、その軸方向(移動方向)全可動範囲において、オイル溜り59に浸っている状態から両摩擦車22,23との接触部に向って上方に回転する。また、上記実施の形態では、ガイドレール62及びスライド部66が、その移動方向全可動範囲に亘ってオイル溜り59に浸っているが、必ずしも全可動範囲に亘って浸っていなくてもよく、ガイドレール62の軸方向一部がオイルレベル59aの上方に位置するように配置してもよい。   In the shift operation means 60, the guide rail 62 and the slide portion 66 are immersed in the oil reservoir 59 over the entire movable range in the axial direction (movement direction). Further, the lower support member 69 is also immersed in the oil reservoir 59 over the entire movable range in the axial direction (moving direction) of the moving member 63. On the other hand, the ball nut portion 65 and the feed screw shaft 61 positioned above the moving member 63 are positioned above the oil level 59a over the entire movable range in the axial direction (moving direction). Further, the upper support member 67 is also positioned above the oil level 59 a over the entire movable range of the moving member 63 in the axial direction (moving direction) and does not immerse in the oil reservoir 59. When the cone ring type CVT 3 rotates forward when the vehicle moves forward, the input side friction wheel 22 rotates in the direction of arrow K in FIG. 2, and the ring 25 is oil in the entire movable range in its axial direction (moving direction). From the state immersed in the reservoir 59, it rotates upward toward the contact portion between the friction wheels 22 and 23. In the above embodiment, the guide rail 62 and the slide portion 66 are immersed in the oil reservoir 59 over the entire movable range in the moving direction. However, the guide rail 62 and the slide portion 66 do not necessarily have to be immersed in the entire movable range. You may arrange | position so that the axial direction part of the rail 62 may be located above the oil level 59a.

従って、コーンリング式CVT3の正逆転にかかわらず、最高速位置から最低速位置に亘るどの変速位置にあっても、常に変速操作手段60は、そのガイドレール62及びスライド部66がオイル溜り59に浸っており、送りねじ軸61及びボールナット部65からなる送りねじ機構は、オイルレベル59aの上方に位置する。送りねじ軸61の回転により、移動部材63を両摩擦車22,23の対向傾斜面に沿って平行に移動する際、ガイドレール62及びスライド部66からなるスライド機構は、常にオイル溜りに位置して、移動部材63を滑らかに平行移動するが、送りねじ機構は、常にオイルレベル59aの上方に位置して、オイル溜り59のオイルを攪拌することはなく、該オイル攪拌によるエネルギロスを生じない。そして、車輌の前進時、リング25も図2の矢印K方向に回転し、該リング25は、オイル溜り59内においてオイルを掻上げ、該リングに引きづられたオイルは、オイルガイド72に案内されながら、上記両摩擦車22,23との接触部に導かれる。該オイルガイド72による充分な量のトラクションオイルが、リング25と両摩擦車22,23との接触部に介在し、これにより前述した剪断力による確実な摩擦動力伝達が行われると共に、回転に伴う滑らかなリング25の軸方向移動が行われ、正確で素速い変速操作が行われる。更に、オイルの一部は、リング25と共に連れ回って、上支持部材67に供給され、また遠心力により飛散されて送りねじ軸61及びボールナット部65に供給される。そして、リング25に付着している更に一部のオイルは、移動部材63の凹溝71に案内されて、オイル溜り59に戻される。   Therefore, regardless of the forward / reverse rotation of the cone ring type CVT 3, regardless of the speed change position from the highest speed position to the lowest speed position, the speed change operation means 60 always has its guide rail 62 and slide portion 66 in the oil reservoir 59. The feed screw mechanism including the feed screw shaft 61 and the ball nut portion 65 is located above the oil level 59a. When the moving member 63 is moved in parallel along the opposed inclined surfaces of the friction wheels 22 and 23 by the rotation of the feed screw shaft 61, the slide mechanism including the guide rail 62 and the slide portion 66 is always located in the oil reservoir. Thus, the moving member 63 is smoothly translated in parallel, but the feed screw mechanism is always located above the oil level 59a and does not stir the oil in the oil reservoir 59, and no energy loss is caused by the oil stirring. . When the vehicle moves forward, the ring 25 also rotates in the direction of the arrow K in FIG. 2. The ring 25 scoops up oil in the oil reservoir 59, and the oil drawn by the ring is guided to the oil guide 72. However, it is guided to the contact portion with the friction wheels 22 and 23. A sufficient amount of traction oil by the oil guide 72 is interposed in the contact portion between the ring 25 and the two friction wheels 22 and 23, whereby reliable frictional power transmission by the above-described shearing force is performed and accompanying rotation. The smooth movement of the ring 25 in the axial direction is performed, and an accurate and quick shifting operation is performed. Further, a part of the oil is accompanied with the ring 25 and supplied to the upper support member 67, and is scattered by centrifugal force and supplied to the feed screw shaft 61 and the ball nut portion 65. Further, a part of the oil adhering to the ring 25 is guided to the concave groove 71 of the moving member 63 and returned to the oil reservoir 59.

前記リング25から飛散されて送りねじ軸61に供給されるオイルは、ボールナット部66との螺合が進行しようとする上記ねじ軸61に供給され、上記リング25の移動に合せて、送りねじ軸とナット部とが螺合する箇所からなる潤滑を必要とする上記送りねじ軸部分に適格に供給されて、送りねじ軸がオイルレベル59aの上方にあっても適切な潤滑により滑らかに移動部材63を移動し得る。また、ガイドレール62とスライド部66とはオイル溜り59に浸って、充分な潤滑により滑らかに移動部材63を案内すると共に、上記スライド部66のスライド作動は、オイル溜り59に浸っていてもオイル溜りの攪拌への影響は少ない。   The oil splashed from the ring 25 and supplied to the feed screw shaft 61 is supplied to the screw shaft 61 where the screwing with the ball nut portion 66 is about to proceed, and the feed screw is moved in accordance with the movement of the ring 25. The feed screw shaft portion that requires lubrication consisting of a portion where the shaft and the nut portion are screwed together is properly supplied, and even if the feed screw shaft is above the oil level 59a, the movable member can be smoothly moved by appropriate lubrication. 63 can be moved. Further, the guide rail 62 and the slide portion 66 are immersed in the oil reservoir 59 to smoothly guide the moving member 63 by sufficient lubrication, and the slide operation of the slide portion 66 can be performed even if immersed in the oil reservoir 59. There is little influence on the stirring of the pool.

コーンリング式CVT3の正転時にあっては、オイル溜り59に浸っている下支持部材69がリング25の軸方向移動を規定する作動部となり、該作動部70はオイル溜り59内においてリング25を滑らかに回転しつつ、その軸方向移動を規定し得る。一方、上支持部材67は、リング25の軸方向移動を許容するため、リング25に付着したオイルにより充分に潤滑されて、リング25の回転を損うことはない。   During the forward rotation of the cone ring type CVT 3, the lower support member 69 immersed in the oil reservoir 59 serves as an operating portion that regulates the axial movement of the ring 25, and the operating portion 70 moves the ring 25 in the oil reservoir 59. Its axial movement can be defined while rotating smoothly. On the other hand, since the upper support member 67 allows the ring 25 to move in the axial direction, the upper support member 67 is sufficiently lubricated by the oil attached to the ring 25 and does not impair the rotation of the ring 25.

一方、車輌の後進時にあっては、リング25が反矢印K方向に回転し、オイル溜り59に浸っているリング25に掻上げられたオイルは、移動部材63の凹溝71に案内されて連れ回られ、上支持部材67に導かれる。コーンリング式CVT3の逆転時にあっては、上支持部材67がリングの軸方向移動を規定する作動部となるが、上記凹溝71に案内された比較的充分なオイルにより潤滑されて、リング25を滑らかに回転しつつ、その軸方向移動を規定する。そして、リング25の回転に伴って更に連れ回られたオイルは、リングと摩擦車との接触部に供給され、前記剪断力による摩擦伝動及びリング25の軸方向移動が行われる。この際、正転時に比較して逆転時にあっては、リングの軸方向位置決め作動部となる上支持部材67及びリングと摩擦車との接触部におけるオイル量は少ないが、車輌の後進状態は、前進時に比して圧倒的にその使用時間が少なく、かつその必要トルク容量及び変速域も小さいので、上記比較的少ないオイル量であっても、摩擦動力伝達及び変速操作に支障を来たすことはなく、正確かつ滑らかに動力伝達及び変速操作を行うことができる。   On the other hand, when the vehicle is moving backward, the ring 25 rotates in the direction of the opposite arrow K, and the oil scooped up by the ring 25 immersed in the oil sump 59 is guided to the concave groove 71 of the moving member 63. It is turned and guided to the upper support member 67. At the time of reverse rotation of the cone ring type CVT 3, the upper support member 67 serves as an operating part that regulates the axial movement of the ring. However, the ring 25 is lubricated by a relatively sufficient oil guided in the concave groove 71. The movement in the axial direction is defined while smoothly rotating. Then, the oil further accompanied by the rotation of the ring 25 is supplied to the contact portion between the ring and the friction wheel, and the frictional transmission by the shearing force and the axial movement of the ring 25 are performed. At this time, the amount of oil in the contact portion between the upper support member 67 and the ring and the friction wheel which is the axial positioning operation portion of the ring is small in the reverse rotation as compared with the normal rotation, but the reverse drive state of the vehicle is Compared to the time of forward movement, the usage time is overwhelmingly small, and the required torque capacity and the speed change range are also small. Therefore, even if the oil amount is relatively small, the frictional power transmission and the speed change operation are not hindered. Thus, power transmission and speed change operation can be performed accurately and smoothly.

ついで、前記支持部材67,69の具体的な構成について、図5及び図6に沿って説明する。なお、上下の支持部材は同じ構成からなるので、一方のみ示して他方を省略する場合がある。   Next, a specific configuration of the support members 67 and 69 will be described with reference to FIGS. Since the upper and lower support members have the same configuration, only one of them may be shown and the other may be omitted.

図5は、スイングアーム方式の支持部材67,69を示す。該支持部材の左右作動部70,70は、枢支軸73を中心に回動自在に支持されているスイングアーム85からなる。左右スイングアーム85,85は、リング25に対して鏡面対称に構成され、それぞれ移動部材63に固定された枠71に枢支軸73を介して回転自在に支持され、その先端にリング側面に接触し得るカム面(摺接面)75が形成されており、リングに近づく方向に回動に対してそれ以上の回動を規制するストッパ76が移動部材63の枠71等により形成されている。   FIG. 5 shows swing arm type support members 67 and 69. The left and right actuating portions 70 and 70 of the support member include a swing arm 85 supported so as to be rotatable about a pivot shaft 73. The left and right swing arms 85, 85 are configured to be mirror-symmetric with respect to the ring 25, are rotatably supported by a frame 71 fixed to the moving member 63 via a pivot shaft 73, and contact the ring side surface at the tip thereof. A possible cam surface (sliding contact surface) 75 is formed, and a stopper 76 that restricts further rotation with respect to rotation in a direction approaching the ring is formed by the frame 71 of the moving member 63 and the like.

ハイブリッド駆動装置1を搭載した車輌が前進している状態では、図4(A)に示すように、コーンリング式CVT3が正転方向(リング25が矢印方向)に回転し、摩擦車との接触部に対してリング25の回転方向上流側となる下支持部材69が作動する。即ち、リング25が矢印方向の回転により、両スイングアーム85,85は、それぞれ引きずられてリング25に互いに近づく方向に回転し、ストッパ76に当接する。この状態では、両スイングアーム85,85の先端カム面75がリング25の両側面を支持するように軸方向位置を規定し、リング25は、該支持部材69によりその回転上流側を位置決め支持されて回転する。なお、この状態での両スイングアームカム面75,75の間隙は、リング25の幅より僅かに広く設定されており、オイルを介在してリング25の回転を許容しつつ軸方向移動を規制するようになっている。右スイングアーム85に示されるように、スイングアームをリングに近づける方向に回転付勢するスプリング77を設けて、スイングアームが作動位置になるように付勢することが好ましい。なお、該スプリング77はなくてもよい。   In a state where the vehicle equipped with the hybrid drive device 1 is moving forward, as shown in FIG. 4A, the cone ring type CVT 3 rotates in the forward rotation direction (the ring 25 is in the direction of the arrow) and contacts the friction vehicle. The lower support member 69 on the upstream side in the rotation direction of the ring 25 with respect to the portion is actuated. That is, when the ring 25 rotates in the direction of the arrow, the swing arms 85 and 85 are respectively dragged and rotated in a direction approaching the ring 25, and come into contact with the stopper 76. In this state, the axial position is defined so that the tip cam surfaces 75 of both swing arms 85, 85 support both side surfaces of the ring 25, and the ring 25 is positioned and supported on the upstream side of the rotation by the support member 69. Rotate. In this state, the gap between the swing arm cam surfaces 75 and 75 is set to be slightly wider than the width of the ring 25, and the axial movement is restricted while allowing rotation of the ring 25 via oil. It is like that. As shown in the right swing arm 85, it is preferable to provide a spring 77 that urges the swing arm to move closer to the ring so as to urge the swing arm to the operating position. The spring 77 may not be provided.

一方、摩擦車接触部に対するリング25の回転方向下流側となる上支持部材67は、図4(B)に示すように、リング25に当接するスイングアーム85(右側参照)は、該リング25の回転により引きずられてストッパ76から離れる方向に回動する。従って、スイングアーム85は、リング25の軸方向移動(振れ)を妨げることなく、リング25は自由に軸方向に移動して、リングの傾斜を妨げることはない。   On the other hand, as shown in FIG. 4B, the upper support member 67 on the downstream side in the rotation direction of the ring 25 with respect to the friction wheel contact portion is a swing arm 85 (see the right side) that contacts the ring 25. It is dragged by the rotation and pivoted away from the stopper 76. Therefore, the swing arm 85 does not hinder the axial movement (swing) of the ring 25, and the ring 25 freely moves in the axial direction and does not hinder the inclination of the ring.

従って、送りねじ軸61の回転によりボールナット部65を移動することにより、移動部材63は、ガイドレール62に案内されて、両摩擦車22,23の対向傾斜面に沿って平行に移動する。この状態で、リング回転の上流側となる下支持部材69は、その作動部である左右スイングアーム85がストッパ76に近接した状態にあってリング25を軸方向に位置決め支持しているので、リング25は、その回転上流側を下支持部材69に摘まれた状態で軸方向に移動し、上支持部材67がリング25の軸方向移動を許容していることが相俟って、上記移動部材63の移動速度に対応した角度で傾斜する。これにより、リング25は、入力側摩擦車22に対してヘリカル状になるので、上記角度に応じた速度で軸方向に移動し、入力側及び出力側の両摩擦車22,23との接触位置を変更することによりコーンリング式CVT3は変速操作される。   Accordingly, by moving the ball nut portion 65 by the rotation of the feed screw shaft 61, the moving member 63 is guided by the guide rail 62 and moves in parallel along the opposing inclined surfaces of the friction wheels 22 and 23. In this state, the lower support member 69 on the upstream side of the ring rotation is in a state in which the left and right swing arms 85, which are operating portions thereof, are close to the stopper 76, and positions and supports the ring 25 in the axial direction. 25 is moved in the axial direction with the rotation upstream side being picked by the lower support member 69, and in combination with the fact that the upper support member 67 allows the ring 25 to move in the axial direction, It inclines at an angle corresponding to the moving speed of 63. As a result, the ring 25 has a helical shape with respect to the input side friction wheel 22, so that the ring 25 moves in the axial direction at a speed corresponding to the angle, and the contact position between the input side and output side friction wheels 22, 23. The cone ring type CVT 3 is changed in speed by changing.

送りねじ軸61を停止することにより、移動部材63の軸方向移動を停止すると、上下支持部材67,69も停止する。この状態では、回転上流側である下支持部材69のスイングアーム85はリング25を軸方向に位置決め支持した状態にあってその位置に停止しており、上支持部材67の両スイングアーム85はリング25の軸方向移動を許容する状態にある。従って、リング25は、回転上流側を一定位置に摘まれた状態で回転を続けるので、自律的にヘルカル角度が0、即ち両摩擦車の軸線l−l,n−nに対して垂直となる平面m−mで回転することになり、該位置での所定回転比に保持されて一定回転での回転を継続する。   When the movement of the moving member 63 is stopped by stopping the feed screw shaft 61, the upper and lower support members 67 and 69 are also stopped. In this state, the swing arm 85 of the lower support member 69 on the upstream side of the rotation is in a state where the ring 25 is positioned and supported in the axial direction and is stopped at that position, and both swing arms 85 of the upper support member 67 are It is in a state of allowing 25 axial movements. Accordingly, since the ring 25 continues to rotate with the upstream side of the rotation being held at a fixed position, the helical angle is autonomously 0, that is, perpendicular to the axes l-l and n-n of both friction wheels. It rotates on the plane mm and is kept at a predetermined rotation ratio at that position and continues to rotate at a constant rotation.

車輌が後進して、コーンリング式CVT3が逆転すると、上支持部材67が、図4(A)に示す摩擦車接触部に対するリング25の回転方向上流側となり、下支持部材69が、図4(B)に示す、リング25の回転方向下流側となり、前述した正転時と同様に、逆転時も作動する。   When the vehicle reverses and the cone ring type CVT 3 reverses, the upper support member 67 becomes upstream in the rotational direction of the ring 25 with respect to the friction wheel contact portion shown in FIG. As shown in B), it is on the downstream side of the rotation direction of the ring 25, and operates in the reverse direction as in the normal rotation described above.

図6に沿って、支持部材67,69の他の実施の形態について説明する。支持部材67,69は、移動部材63における枠71の内径側に2本の頭付軸73,73が植設され、かつ止めピン90により枠71に抜止めされている。これら軸73にはそれぞれアーム85,85が回転自在に支持されており、かつアームボス85aと上記枠71との間にトーションスプリング91が介在して、両アームをリング25に近づく方向に付勢している。また、アーム85がリング25に近づく所定位置において、該アームが当接してその位置に保持されるストッパ76が上記枠71に設けられている。各両アーム85,85は、下支持部材69にあっては、リング25の正転方向にてそれぞれ先端が近づく方向に回動付勢されており、上支持部材67にあっては、リング25の逆転方向にてそれぞれ先端が近づく方向に回動付勢されている。   Another embodiment of the support members 67 and 69 will be described with reference to FIG. The support members 67 and 69 have two headed shafts 73 and 73 planted on the inner diameter side of the frame 71 in the moving member 63, and are secured to the frame 71 by a retaining pin 90. Arms 85 and 85 are rotatably supported by these shafts 73, respectively, and a torsion spring 91 is interposed between the arm boss 85a and the frame 71 to urge both arms toward the ring 25. ing. In addition, a stopper 76 is provided on the frame 71 so that the arm 85 abuts and is held at the predetermined position at which the arm 85 approaches the ring 25. In the lower support member 69, each arm 85, 85 is urged to rotate in the direction in which the tip approaches in the forward rotation direction of the ring 25, and in the upper support member 67, the ring 25 In the reverse rotation direction, the rotation is biased in the direction in which the tips approach each other.

図6(A),(B)に示す作動部70は、上記アーム85の先端に支持軸92が固定されており、該支持軸92にはその頭92aとアーム85との間に挟持されてボール(又はローラ)ベアリング93が装着されている。なお、左右のボールベアリング93は、断面が平行四辺形からなるリング25の側面に丁度当接するように、枠71の肉厚を変えることにより径方向位置が異なっている。 FIG. 6 (A), the operation unit 70 1 shown in (B) is the support shaft 92 to the distal end of the arm 85 is fixed to the support shaft 92 is interposed between the head 92a and the arm 85 A ball (or roller) bearing 93 is mounted. The left and right ball bearings 93 have different radial positions by changing the wall thickness of the frame 71 so that the cross section just contacts the side surface of the ring 25 having a parallelogram shape.

従って、リング25の摩擦車接触部に対して回転上流側に位置する支持部(正転であっては下支持部材69、逆転であっては上支持部材67)の作動部材70は、アーム85がトーションスプリング91により該リングに近づく方向に回転してストッパ76に当接した位置となる。この状態では、両ボールベアリング93,93がリング25を挟持して軸方向に位置決めされる。この際、ボールベアリング93は、そのアウタレースがリング25の側面に当接して回転し、リング25の回転を損うことがなく、かつ該リング25の軸方向位置を正確にかつ長期に亘って摩耗することなく位置決めすることができる。 Accordingly, the actuating member 70 1 of the support portion located on the rotation upstream of the friction wheel contact portion (lower support member 69 is a forward, above a reverse supporting member 67) of the ring 25, the arms 85 is rotated by the torsion spring 91 in a direction approaching the ring and is brought into contact with the stopper 76. In this state, the ball bearings 93 and 93 are positioned in the axial direction with the ring 25 interposed therebetween. At this time, the ball bearing 93 rotates while the outer race abuts against the side surface of the ring 25, the rotation of the ring 25 is not impaired, and the axial position of the ring 25 is worn accurately and over a long period of time. It is possible to position without doing.

一方、リング25の回転下流側に位置する支持部材(正転であっては上支持部材67、逆転であっては下支持部材69)の作動部材70は、リング25に引きずられてアーム85がストッパ76から離れるように回動して、リング25に押されて該リングの軸方向移動を許容する。この際も同様に、当接側のボールベアリング93は、リングに当接して回転し、リング25の回転を損うことがない。 On the other hand, the actuating member 70 1 of the support member located on the rotation downstream side (upper support member 67 is a forward, lower a reverse supporting member 69) of the ring 25, the arm 85 is dragged by the ring 25 Rotates away from the stopper 76 and is pushed by the ring 25 to allow axial movement of the ring. Similarly, the ball bearing 93 on the contact side rotates in contact with the ring and does not impair the rotation of the ring 25.

なお、上記実施の形態は、アーム85の先端に回転部材としてボールベアリングを装着したが、回転部材は、ボールベアリングに限らず、ニードルベアリング,軸受鋼,合成樹脂又は鉄の外周にフッ素樹脂等の自己潤滑性に優れた樹脂をコーティングしたローラ,ブッシュであってもよい。また、アームの先端に、セラミック又は基台の表面にフッ素コーティングしたシューを取り付けてもよい。更に、作動部に、底面が傾斜面となる収容空間を有するケージと、該ケージの収容空間に、リングの回転方向に移動自在に収納されるボール又は駒等のスプラグと、を備えたワンウェイクラッチを用いてもよい。   In the above embodiment, a ball bearing is mounted as a rotating member at the tip of the arm 85. However, the rotating member is not limited to the ball bearing, and the outer periphery of needle bearing, bearing steel, synthetic resin, or iron is made of fluorine resin or the like. A roller or bush coated with a resin excellent in self-lubricating property may be used. Further, a shoe coated with fluorine on the surface of the ceramic or the base may be attached to the tip of the arm. Furthermore, the one-way clutch provided with a cage having a receiving space whose bottom surface is an inclined surface in the operating portion, and a sprag such as a ball or a piece that is stored in the receiving space of the cage so as to be movable in the rotation direction of the ring. May be used.
