Description

本発明は動力伝達機構の潤滑装置に係り、特に、攪拌等によって潤滑油に混入した気泡を低減する技術に関するものである。   The present invention relates to a lubricating device for a power transmission mechanism, and more particularly to a technique for reducing bubbles mixed in lubricating oil by stirring or the like.

動力伝達用の回転体を潤滑油によって潤滑する動力伝達機構の潤滑装置が知られている。このような動力伝達機構の潤滑装置において、例えば動力伝達用の回転体の一部が潤滑油に浸漬される油浴方式によって潤滑される場合、潤滑油が攪拌されて気泡が混入する可能性がある。潤滑油に気泡が混入すると、潤滑油の体積が大きくなるため、実質的な潤滑油の供給量が不足する恐れがある。このため、特許文献１では、オイルポンプの回転速度すなわち吐出量を制御することにより、気泡の混入に拘らず所定量の潤滑油を供給できるようにしている。   2. Description of the Related Art A power transmission mechanism lubrication device that lubricates a power transmission rotating body with lubricating oil is known. In such a power transmission mechanism lubrication device, for example, when a part of a power transmission rotating body is lubricated by an oil bath method in which it is immersed in lubricating oil, there is a possibility that the lubricating oil is agitated and bubbles are mixed therein. is there. When bubbles are mixed in the lubricating oil, the volume of the lubricating oil increases, and there is a risk that the actual supply amount of the lubricating oil will be insufficient. For this reason, in Patent Document 1, by controlling the rotation speed of the oil pump, that is, the discharge amount, a predetermined amount of lubricating oil can be supplied regardless of the mixing of bubbles.

特開２０１３−１９４８６３号公報JP2013-194863A

しかしながら、このように潤滑油の供給量を増加すると、油浴潤滑の場合は勿論、潤滑油を潤滑部位へ供給して吐出する強制潤滑の場合でも、潤滑油量の増加に伴って攪拌抵抗が大きくなるため、動力伝達効率が損なわれる可能性があった。潤滑油は一般に粘性が高いため、オイルポンプの吐出量を増やしても気泡が潰れて無くなることはなく、気泡による体積増加によって上記問題が発生する。   However, when the supply amount of the lubricating oil is increased in this way, not only in the case of oil bath lubrication, but also in the case of forced lubrication in which the lubricating oil is supplied to the lubrication site and discharged, the stirring resistance increases as the lubricating oil amount increases. Since it becomes large, power transmission efficiency may be impaired. Since the lubricating oil is generally high in viscosity, even if the discharge amount of the oil pump is increased, the bubbles are not crushed and lost, and the above problem occurs due to the increase in volume due to the bubbles.

本発明は以上の事情を背景として為されたもので、その目的とするところは、攪拌等によって潤滑油に混入した気泡を簡便な手段で低減することにある。   The present invention has been made in the background of the above circumstances, and its object is to reduce bubbles mixed in the lubricating oil by stirring or the like by a simple means.

本発明は、動力伝達用の回転体を潤滑油によって潤滑する動力伝達機構の潤滑装置において、(a) 前記回転体よりも大径の円筒部を備え、その回転体と同心に設けられてその回転体と一体的に回転させられる回転側油受け部材と、(b) 前記回転体の外周側に位置するように固定部材に一体的に設けられ、その回転体を潤滑した後の潤滑油を受け止めるとともに、一端部が前記回転側油受け部材の前記円筒部の内側へ挿入されて、受け止めた潤滑油をその回転側油受け部材内へ流入させる固定側油受け部材と、を有することを特徴とする。   The present invention relates to a lubricating device for a power transmission mechanism for lubricating a power transmission rotating body with lubricating oil. (A) A cylindrical portion having a diameter larger than that of the rotating body is provided concentrically with the rotating body. A rotation-side oil receiving member that is rotated integrally with the rotating body; and (b) a lubricating oil that is provided integrally with the fixed member so as to be positioned on the outer peripheral side of the rotating body and lubricates the rotating body. A fixed-side oil receiving member that receives and receives the lubricating oil that is inserted into the cylindrical portion of the rotating-side oil receiving member and has one end thereof inserted into the cylindrical portion of the rotating-side oil receiving member. And

このような動力伝達機構の潤滑装置においては、回転体を潤滑した後の潤滑油が固定側油受け部材によって受け止められ、回転側油受け部材内へ流入させられるため、その回転側油受け部材が回転体と一体的に回転させられる際に、回転速度に応じて発生する遠心力の作用で気泡が潰されて消失する。これにより、潤滑油に混入した気泡の量が低減され、気泡に起因する潤滑油の体積増加が抑制されるため、実質的な潤滑油の供給量不足が抑制されて適切に潤滑が行なわれるとともに、潤滑油の体積増加に起因する攪拌抵抗の増加に伴う動力伝達効率の悪化が抑制される。また、動力伝達機構を構成している既存の回転体の近傍に回転側油受け部材および固定側油受け部材を設けるだけで良いため、僅かな設計変更により簡便に実施できる。   In such a power transmission mechanism lubrication device, the lubricating oil after the rotating body is lubricated is received by the fixed-side oil receiving member and flows into the rotating-side oil receiving member. When rotating integrally with the rotating body, the bubbles are crushed and disappear by the action of centrifugal force generated according to the rotation speed. As a result, the amount of bubbles mixed in the lubricating oil is reduced, and an increase in the volume of the lubricating oil due to the bubbles is suppressed, so that a substantial supply amount of lubricating oil is suppressed and proper lubrication is performed. And the deterioration of the power transmission efficiency accompanying the increase in stirring resistance resulting from the increase in the volume of lubricating oil is suppressed. In addition, since it is only necessary to provide the rotation-side oil receiving member and the fixed-side oil receiving member in the vicinity of the existing rotating body constituting the power transmission mechanism, it can be easily implemented with a slight design change.

本発明の一実施例である車両用動力伝達機構の潤滑装置の要部を説明する断面図である。It is sectional drawing explaining the principal part of the lubricating device of the power transmission mechanism for vehicles which is one Example of this invention.

本発明は、車両用動力伝達機構の潤滑装置に好適に適用されるが、車両用以外の動力伝達機構の潤滑装置にも適用され得る。動力伝達用の回転体の一部が潤滑油に浸漬される油浴方式によって潤滑される箇所が存在する場合に、潤滑油が攪拌されて気泡が混入する可能性があり、本発明が好適に適用されるが、潤滑油を潤滑部位へ供給して吐出する強制潤滑の場合でも、潤滑油が飛散する際などに気泡が混入する可能性があるため、油浴方式による潤滑箇所が存在するか否かに拘らず本発明が適用され得る。   The present invention is preferably applied to a lubricating device for a power transmission mechanism for a vehicle, but can also be applied to a lubricating device for a power transmission mechanism other than for a vehicle. When there is a portion to be lubricated by an oil bath method in which a part of a rotating body for power transmission is immersed in lubricating oil, the lubricating oil may be agitated and air bubbles may be mixed in, and the present invention is suitable. Although it is applied, even in the case of forced lubrication in which lubricating oil is supplied to the lubrication site and discharged, bubbles may be mixed in when the lubricating oil scatters. The present invention can be applied regardless of whether or not.

回転側油受け部材は、例えば略水平な回転軸心まわりに回転させられる回転体に配設され、固定側油受け部材は、回転体から流下した潤滑油を受け止めるように、その回転体の下方側位置に配設されるが、略垂直な回転軸心まわりに回転させられる回転体から外周側へ飛散した潤滑油を固定側油受け部材により受け止めて回転側油受け部材内へ流入させるなど、種々の態様が可能である。また、例えばベルト式無段変速機の可変プーリや噛合い回転させられる歯車列など径方向に連結されている回転体に対しては、その外周側に回転側油受け部材を配設することができないため、その回転側油受け部材を回転体に対して軸方向へオフセットして配設し、回転体の外周側に部分的に設けられた固定側油受け部材によって潤滑油を受け止めて、回転側油受け部材内へ流入させるように構成される。   The rotation-side oil receiving member is disposed, for example, on a rotating body that is rotated around a substantially horizontal rotation axis, and the fixed-side oil receiving member is below the rotating body so as to receive the lubricating oil that has flowed down from the rotating body. Although it is disposed at the side position, lubricating oil splashed from the rotating body rotated around the substantially vertical rotation axis to the outer peripheral side is received by the fixed side oil receiving member and flows into the rotating side oil receiving member, etc. Various embodiments are possible. Further, for example, a rotating oil receiving member may be disposed on the outer peripheral side of a rotating body connected in a radial direction such as a variable pulley of a belt-type continuously variable transmission or a gear train rotated in mesh. Therefore, the rotating side oil receiving member is offset in the axial direction with respect to the rotating body, and the lubricating oil is received by the fixed side oil receiving member partially provided on the outer peripheral side of the rotating body to rotate. It is comprised so that it may flow in into a side oil receiving member.

以下、本発明の実施例を、図面を参照しつつ詳細に説明する。
図１は、本発明の一実施例である車両用動力伝達機構の潤滑装置１０の要部を説明する断面図である。車両用動力伝達機構の一部を構成しているベルト式無段変速機１２は、入力軸１４に設けられた有効径が可変、すなわち溝幅が可変のプライマリ可変プーリ１６と、出力軸１８に設けられた有効径が可変、すなわち溝幅が可変のセカンダリ可変プーリ２０と、それ等の可変プーリ１６、２０に巻き掛けられた伝動ベルト２２とを備えており、可変プーリ１６、２０と伝動ベルト２２との間の摩擦力を介して動力伝達が行われる。入力軸１４および出力軸１８は、略水平で且つ車両幅方向と略平行な軸心まわりに回転可能に配設され、入力軸１４には図示しないエンジンからトルクコンバータ等を介して駆動力が伝達される一方、出力軸１８からは終減速装置等を介して駆動輪へ駆動力が伝達される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view illustrating a main part of a lubricating device 10 for a vehicle power transmission mechanism according to an embodiment of the present invention. A belt-type continuously variable transmission 12 constituting a part of a vehicle power transmission mechanism includes a primary variable pulley 16 having a variable effective diameter provided on an input shaft 14, that is, a variable groove width, and an output shaft 18. The secondary variable pulley 20 having a variable effective diameter, that is, a variable groove width, and a transmission belt 22 wound around the variable pulleys 16 and 20 are provided. The variable pulleys 16 and 20 and the transmission belt are provided. Power is transmitted through the frictional force between the two. The input shaft 14 and the output shaft 18 are disposed so as to be rotatable about an axis that is substantially horizontal and substantially parallel to the vehicle width direction, and driving force is transmitted to the input shaft 14 from an engine (not shown) via a torque converter or the like. On the other hand, the driving force is transmitted from the output shaft 18 to the driving wheels via a final reduction gear or the like.

一対の可変プーリ１６および２０は、入力軸１４、出力軸１８にそれぞれ固定された入力側固定回転体２４、出力側固定回転体２６と、入力軸１４、出力軸１８に対して軸まわりの相対回転不能かつ軸方向の移動可能に設けられた入力側可動回転体２８、出力側可動回転体３０と、それらの間のＶ溝幅を変更する推力を付与する油圧アクチュエータとしての入力側油圧シリンダ３２、出力側油圧シリンダ３４とを備えて構成されている。そして、入力側油圧シリンダ３２へ供給されるプライマリ油圧Ｐｐが制御されることにより、両可変プーリ１６、２０のＶ溝幅が変化して伝動ベルト２２の掛かり径（有効径）が変更され、変速比が連続的に変化させられる。また、出力側油圧シリンダ３４の油圧（セカンダリ油圧Ｐｓ）が調圧制御されることにより、伝動ベルト２２が滑りを生じないようにベルト挟圧力が制御される。   The pair of variable pulleys 16 and 20 includes an input side fixed rotator 24 and an output side fixed rotator 26 fixed to the input shaft 14 and the output shaft 18, respectively, and relative to the input shaft 14 and the output shaft 18. An input-side movable rotating body 28 and an output-side movable rotating body 30 that are provided so as to be unrotatable and movable in the axial direction, and an input-side hydraulic cylinder 32 as a hydraulic actuator that applies thrust to change the V-groove width therebetween. The output side hydraulic cylinder 34 is provided. Then, by controlling the primary hydraulic pressure Pp supplied to the input side hydraulic cylinder 32, the V-groove widths of both variable pulleys 16 and 20 are changed, and the engagement diameter (effective diameter) of the transmission belt 22 is changed. The ratio is continuously changed. Further, the pressure of the output side hydraulic cylinder 34 (secondary hydraulic pressure Ps) is controlled so that the belt clamping pressure is controlled so that the transmission belt 22 does not slip.

一方、潤滑装置１０は、機械式或いは電動式のオイルポンプ４０によってオイルパン４２から汲み上げた潤滑油を動力伝達機構の各部へ送り出して、油浴潤滑や強制潤滑によってその動力伝達機構の各部を潤滑するようになっている。前記ベルト式無段変速機１２に関しては、例えば入力軸１４や出力軸１８、或いは変速機ケース４４などに設けられた油路を介して可変プーリ１６、２０へ潤滑油を供給することにより、その可変プーリ１６、２０と伝動ベルト２２との接触部位等を潤滑するようになっている。各部を潤滑した潤滑油は、変速機ケース４４の底部やドレーン油路等を介してオイルパン４２へ戻され、再びオイルポンプ４０により汲み上げられて各部へ送り出される。なお、前記プライマリ油圧Ｐｐおよびセカンダリ油圧Ｐｓなどの作動油についても、オイルポンプ４０から出力された共通の潤滑油を用いることができる。   On the other hand, the lubrication device 10 sends the lubricating oil pumped up from the oil pan 42 by the mechanical or electric oil pump 40 to each part of the power transmission mechanism, and lubricates each part of the power transmission mechanism by oil bath lubrication or forced lubrication. It is supposed to be. With respect to the belt type continuously variable transmission 12, for example, by supplying lubricating oil to the variable pulleys 16 and 20 through an oil passage provided in the input shaft 14, the output shaft 18, or the transmission case 44, A contact portion between the variable pulleys 16 and 20 and the transmission belt 22 is lubricated. The lubricating oil that has lubricated each part is returned to the oil pan 42 via the bottom of the transmission case 44, the drain oil passage, and the like, pumped up again by the oil pump 40, and sent to each part. The common lubricating oil output from the oil pump 40 can also be used for the hydraulic oil such as the primary hydraulic pressure Pp and the secondary hydraulic pressure Ps.

ここで、ベルト式無段変速機１２を潤滑した潤滑油は、下方へ流下して変速機ケース４４の底部を通ってオイルパン４２へ戻されるが、一対の可変プーリ１６、２０のうち下側に位置するセカンダリ可変プーリ２０には、回転側油受け部材５０が取り付けられている。回転側油受け部材５０は、セカンダリ可変プーリ２０よりも大径の円筒部５２をセカンダリ可変プーリ２０と同心に備えているとともに、伝動ベルト２２と干渉しないようにベルト掛かり部分から軸方向へオフセットした位置に配設されており、例えば出力側油圧シリンダ３４等に固設されて一体的に回転させられるようになっている。円筒部５２の開口側、すなわちベルト掛かり部分側の端部には、所定寸法の内向きフランジ５４が設けられており、所定量の潤滑油を保持できるようになっている。この回転側油受け部材５０が取り付けられたセカンダリ可変プーリ２０は、動力伝達用の回転体である。   Here, the lubricating oil that has lubricated the belt-type continuously variable transmission 12 flows down and returns to the oil pan 42 through the bottom of the transmission case 44, but the lower side of the pair of variable pulleys 16, 20. A rotation-side oil receiving member 50 is attached to the secondary variable pulley 20 located at the position. The rotation-side oil receiving member 50 is provided with a cylindrical portion 52 having a diameter larger than that of the secondary variable pulley 20 concentrically with the secondary variable pulley 20 and is offset in the axial direction from the belt hook portion so as not to interfere with the transmission belt 22. For example, it is fixed to the output side hydraulic cylinder 34 or the like and can be rotated integrally therewith. An inward flange 54 having a predetermined size is provided on the opening side of the cylindrical portion 52, that is, the end portion on the belt hooking portion side, so that a predetermined amount of lubricating oil can be held. The secondary variable pulley 20 to which the rotation side oil receiving member 50 is attached is a rotating body for power transmission.

また、セカンダリ可変プーリ２０のベルト掛かり部分の外周側であって、潤滑油が流下する下方位置には、固定側油受け部材６０が配設され、変速機ケース４４に一体的に固設されている。固定側油受け部材６０は、セカンダリ可変プーリ２０と同心の半円筒形状或いはそれより狭い角度の部分円筒形状の受け樋部６２を備えており、矢印ａで示すようにセカンダリ可変プーリ２０から飛散乃至は流下した潤滑油を受け止める。受け樋部６２の径寸法は、セカンダリ可変プーリ２０よりも大径で且つ回転側油受け部材５０の円筒部５２よりも小径であるとともに、その回転側油受け部材５０側の一端部は円筒部５２の内周側へ挿入されており、受け止められた潤滑油は矢印ｂ、ｃで示すように回転側油受け部材５０側へ流動して円筒部５２内に流入させられる。セカンダリ可変プーリ２０の軸心は略水平で、受け樋部６２も略水平であるが、回転側油受け部材５０側へ向かうに従って下方へ傾斜させることも可能である。受け樋部６２の他端部、すなわち回転側油受け部材５０と反対側の端部には、水平方向の開口を閉塞する油止め部６４が設けられており、その他端部側から潤滑油が流出することが防止されるようになっている。固定側油受け部材６０が固設された変速機ケース４４は、車両に一体的に位置固定に配設された固定部材に相当する。   A fixed-side oil receiving member 60 is disposed on the outer peripheral side of the belt-hanging portion of the secondary variable pulley 20 at a lower position where the lubricating oil flows down, and is integrally fixed to the transmission case 44. Yes. The fixed-side oil receiving member 60 is provided with a semi-cylindrical receiving rod portion 62 concentric with the secondary variable pulley 20 or a partial cylindrical shape with a narrower angle than the secondary variable pulley 20, and is scattered from the secondary variable pulley 20 as indicated by an arrow a. Receives the lubricant that has flowed down. The diameter of the receiving flange 62 is larger than that of the secondary variable pulley 20 and smaller than that of the cylindrical portion 52 of the rotation-side oil receiving member 50, and one end on the rotation-side oil receiving member 50 side is cylindrical. The received lubricating oil is inserted into the inner peripheral side of 52 and flows toward the rotation-side oil receiving member 50 as shown by arrows b and c, and flows into the cylindrical portion 52. The shaft center of the secondary variable pulley 20 is substantially horizontal, and the receiving flange 62 is also substantially horizontal, but can be inclined downward toward the rotation-side oil receiving member 50 side. An oil stopper 64 that closes the horizontal opening is provided at the other end of the receiving rod 62, that is, the end opposite to the rotation-side oil receiving member 50, and lubricating oil is supplied from the other end. Outflow is prevented. The transmission case 44 to which the fixed-side oil receiving member 60 is fixed corresponds to a fixed member that is disposed in a fixed manner in the vehicle.

したがって、矢印ａで示すようにセカンダリ可変プーリ２０から飛散乃至は流下した潤滑油は、固定側油受け部材６０によって受け止められ、矢印ｂ、ｃで示すように流動して回転側油受け部材５０内に流入する。回転側油受け部材５０は、セカンダリ可変プーリ２０と一体的に回転させられるため、回転側油受け部材５０内の潤滑油は、回転速度に応じて発生する遠心力によって円筒部５２の内周面に押圧され、その潤滑油内に混入している気泡の一部は潰されて消泡する。回転側油受け部材５０内の潤滑油が所定量以上に増加したり、回転速度が遅くなって遠心力が低下したりすると、その回転側油受け部材５０内の潤滑油は、矢印ｄで示すように内向きフランジ５４を乗り越えて流下し、変速機ケース４４の底部を通ってオイルパン４２へ戻される。なお、固定側油受け部材６０の受け樋部６２は必ずしも部分円筒形状である必要はなく、例えば断面がＵ字形状乃至はコの字形状等の受け樋部６２を採用することも可能で、必要に応じて回転側油受け部材５０の円筒部５２の内側へ挿入される幅狭の案内部等を設けて、その円筒部５２内へ潤滑油を流入させるようにしても良い。   Therefore, the lubricating oil scattered or flown down from the secondary variable pulley 20 as indicated by the arrow a is received by the fixed-side oil receiving member 60 and flows as indicated by the arrows b and c to flow inside the rotating-side oil receiving member 50. Flow into. Since the rotation-side oil receiving member 50 is rotated integrally with the secondary variable pulley 20, the lubricating oil in the rotation-side oil receiving member 50 is caused by the centrifugal force generated according to the rotation speed to the inner peripheral surface of the cylindrical portion 52. A part of the bubbles mixed in the lubricating oil is crushed and defoamed. When the lubricating oil in the rotation-side oil receiving member 50 increases to a predetermined amount or more, or when the rotation speed becomes slow and the centrifugal force decreases, the lubricating oil in the rotation-side oil receiving member 50 is indicated by an arrow d. In this way, the vehicle flows over the inward flange 54 and flows back to the oil pan 42 through the bottom of the transmission case 44. The receiving flange portion 62 of the fixed-side oil receiving member 60 does not necessarily have a partial cylindrical shape. For example, the receiving flange portion 62 having a U-shaped or U-shaped cross section may be employed. If necessary, a narrow guide portion or the like that is inserted into the inside of the cylindrical portion 52 of the rotation-side oil receiving member 50 may be provided so that the lubricating oil flows into the cylindrical portion 52.

このように、本実施例の動力伝達機構の潤滑装置１０によれば、セカンダリ可変プーリ２０を潤滑した後の潤滑油が固定側油受け部材６０によって受け止められ、回転側油受け部材５０内へ流入させられるため、その回転側油受け部材５０がセカンダリ可変プーリ２０と一体的に回転させられる際に、回転速度に応じて発生する遠心力の作用で気泡が潰されて消失する。これにより、潤滑油に混入した気泡の量が低減され、気泡に起因する潤滑油の体積増加が抑制されるため、実質的な潤滑油の供給量不足が抑制されて適切に潤滑が行なわれるとともに、潤滑油の体積増加に起因する攪拌抵抗の増加に伴う動力伝達効率の悪化が抑制される。また、動力伝達機構を構成している既存の回転体、本実施例ではセカンダリ可変プーリ２０の近傍に回転側油受け部材５０および固定側油受け部材６０を設けるだけで良いため、僅かな設計変更により簡便に実施できる。   Thus, according to the lubricating device 10 of the power transmission mechanism of the present embodiment, the lubricating oil after lubricating the secondary variable pulley 20 is received by the fixed-side oil receiving member 60 and flows into the rotating-side oil receiving member 50. Therefore, when the rotation-side oil receiving member 50 is rotated integrally with the secondary variable pulley 20, the bubbles are crushed and disappear by the action of the centrifugal force generated according to the rotation speed. As a result, the amount of bubbles mixed in the lubricating oil is reduced, and an increase in the volume of the lubricating oil due to the bubbles is suppressed, so that a substantial supply amount of lubricating oil is suppressed and proper lubrication is performed. And the deterioration of the power transmission efficiency accompanying the increase in stirring resistance resulting from the increase in the volume of lubricating oil is suppressed. Further, since it is only necessary to provide the rotating side oil receiving member 50 and the fixed side oil receiving member 60 in the vicinity of the existing rotating body constituting the power transmission mechanism, in the present embodiment, the secondary variable pulley 20, a slight design change. Can be carried out more easily.

以上、本発明の実施例を図面に基づいて詳細に説明したが、これはあくまでも一実施形態であり、本発明は当業者の知識に基づいて種々の変更、改良を加えた態様で実施することができる。   As mentioned above, although the Example of this invention was described in detail based on drawing, this is an embodiment to the last, and this invention is implemented in the aspect which added various change and improvement based on the knowledge of those skilled in the art. Can do.
