Further, a flow of the lubricant oil trying to flow in a reverse direction is restricted by the upward inclination part 44a and at the same time a flow of lubricant oil toward the passing openings 37, 38 is promoted by an upward inclination part 44a and the downward inclination of the bottom surface 58.SELECTED DRAWING: Figure 3

Description

  The present invention relates to an oil garter and a transmission including the same.

  Japanese Patent Laying-Open No. 2011-7208 (Patent Document 1) includes an introduction portion extending in the tangential direction of the ring gear, and a flow path portion orthogonal to the introduction portion and extending in the rotation axis direction of the ring gear. An oil garter that supplies lubricating oil from the flow path portion to the tooth surface of each gear or a portion requiring lubrication such as a synchro mechanism by introducing the lubricating oil scraped up by the ring gear from the introduction portion and distributing it to the flow path portion. Have been described.

  In this oil garter, a vertical wall extending to the vicinity of the upper inner wall of the transmission case is provided at a position opposite to the direction in which the lubricating oil scraped up by the ring gear comes in, so that the flying lubricating oil collides with the vertical wall. The lubricant that flows down the wall is collected.

JP 2011-7208 A

  However, in the oil garter described above, the collision energy of the lubricating oil increases as the rotational speed of the ring gear increases. Therefore, when the rotational speed of the ring gear becomes high, the introduction portion after the lubricating oil collides with the vertical wall Backflow, and the collection efficiency is reduced, leading to a reduction in lubrication performance.

  The present invention has been made in view of the above, and an object of the present invention is to provide a technique capable of improving the lubrication performance.

  The oil garter of the present invention and the transmission including the oil garter employ the following means in order to achieve the above-described object.

  According to the preferred embodiment of the oil garter according to the present invention, an oil garter that collects the lubricating oil scraped up by the rotating member and supplies it to the site requiring lubrication is configured. The oil garter includes an introduction part and a supply flow path part. The introducing portion is configured to extend in the scattering direction of the lubricating oil that is scraped up by the rotating member and to introduce the lubricating oil that is scraped up by the rotating member. Moreover, the introduction part is partitioned into a first introduction part and a second introduction part by a partition wall. The first introduction part is disposed on the front side in the scattering direction across the partition wall, and has a suppressing part that suppresses the flow of the lubricating oil to the side opposite to the scattering direction. The second introduction part is disposed on the rear side in the scattering direction across the partition wall and has a bottom surface that is inclined downward toward the supply flow path part. Moreover, the supply flow path part is comprised so that the lubricating oil extended in the direction which cross | intersects the extension direction of an introduction part and introduced into the introduction part may be supplied to a lubrication required site | part. Then, the lubricating oil introduced into the first introduction part is introduced into the supply flow path part through the first opening, and the lubricating oil introduced into the second introduction part is introduced into the supply flow path part through the second opening. It is configured to be introduced.

  The “scattering direction” in the present invention typically corresponds to a direction perpendicular to the rotation axis of the rotating member, for example, a tangential direction of the rotating member. The “direction perpendicular to the rotation axis of the rotating member” corresponds to a direction having a direction vector whose inner product is 0 with respect to the direction vector of the rotating shaft of the rotating member. In addition, the “crossing direction” in the present invention typically corresponds to an orthogonal direction.

  According to the present invention, since the introduction portion into which the lubricating oil scraped up by the rotation member is introduced is divided into the first introduction portion and the second introduction portion by the partition wall, the rotation speed of the rotation member is At a relatively low speed, the flying lubricating oil can be collided against the partition wall and collected by the first introduction part and introduced into the supply flow path part from the first opening. When the vehicle starts to get over the partition wall, the second introduction part can collect the lubricating oil and can introduce it into the supply channel part from the second opening.

 In addition, since the 1st introducing | transducing part has a suppressing part which suppresses the flow to the opposite direction to the splashing direction of lubricating oil, it is suppressed that the lubricating oil which collided with the partition wall flows backward through the 1st introducing | transducing part. it can. Further, since the bottom surface of the second introduction part is configured to have a downward slope toward the supply flow path part, the lubricating oil collected by the second introduction part can be quickly introduced into the supply flow path part. it can. As a result, the lubricating oil can be efficiently collected without depending on the rotation speed of the rotating member, and the lubricating oil can be quickly supplied to the portion requiring lubrication. As a result, the lubrication performance is improved.

  According to the further form of the oil garter which concerns on this invention, the partition wall is comprised so that the lubricating oil which collides with the said partition wall may be guide | induced to the supply flow-path part side.

  According to this embodiment, it is possible to suppress the retention of the lubricating oil in the first introduction part, and it is possible to quickly introduce the lubricating oil into the supply flow path part. Thereby, lubrication performance improves.

  According to the further form of the oil garter which concerns on this invention, the partition wall is comprised so that it may have a curved surface from which the 2nd introduction part side becomes convex. Here, the “curved surface” in the present invention typically corresponds to an arc shape.

  According to this embodiment, since the flow direction of the lubricating oil can be changed smoothly, the lubricating oil can be guided to the supply flow path portion more quickly than in the case where the partition wall is a flat surface.

  According to the further form of the oil garter which concerns on this invention, the control part forms lubricating oil to the opposite side to a scattering direction by forming the bottom face of a 1st introducing | transducing part in the upward slope toward the direction away from a partition wall. It is comprised so that the flow of may be suppressed.

  According to this embodiment, the backflow of the lubricating oil can be suppressed with a simple configuration. Moreover, introduction of the lubricating oil collected by the first introduction part into the supply flow path part can be promoted by the inclination.

  According to the further form of the oil garter which concerns on this invention, the introducing | transducing part has a channel | path part comprised so that it might extend in the scattering direction of lubricating oil. The passage portion is configured to open at both ends in the extending direction of the passage portion, and is configured to communicate with the first introduction portion through one of the openings. And it is comprised so that a part of lubricating oil introduce | transduced into the 1st introduction part may flow in from one opening, and may flow out from the other opening.

  According to this embodiment, the lubricating oil can be satisfactorily supplied also to the portion requiring lubrication disposed on the side opposite to the side where the rotating member is disposed across the introduction portion in the scattering direction of the lubricating oil. As a result, the lubrication performance can be further improved.

  According to a preferred mode of the transmission according to the present invention, a transmission is provided that includes an input shaft, an output shaft, a speed change mechanism, the oil garter according to the present invention of any one of the aspects described above, and a case. The The transmission mechanism is configured to transmit the rotation of the input shaft to the output shaft with a changeable gear ratio. Further, the speed change mechanism has a plurality of gears. The case is configured to accommodate an input shaft, an output shaft, a transmission mechanism, and an oil garter. The transmission is configured to collect the lubricating oil picked up by at least one of the gears with an oil garter and supply the collected lubricating oil to the transmission mechanism. The “transmission mechanism” in the present invention typically corresponds to a drive gear, a driven gear that meshes with the drive gear, and a synchro mechanism.

  According to the present invention, since the oil garter according to the present invention of any one of the aspects described above is provided, the same effect as the effect of the oil garter of the present invention, for example, the effect of improving the lubrication performance and the like are exhibited. be able to.

  According to the further form of the transmission which concerns on this invention, the case has a protrusion part in the position corresponding to the upper direction of a 2nd introduction part. And it is comprised so that a part of lubricating oil scraped up with the gearwheel may be made to collide with a protrusion part, and it may introduce | transduce into the 2nd introduction part by transmitting the said protrusion part. The protrusion in the present invention typically corresponds to a rib formed on the case.

  According to the present embodiment, even when the scraped lubricating oil scatters above the oil garter, the lubricating oil collides with the protruding portion and is collected by the second introducing portion along the protruding portion. be able to. Thereby, lubricating oil can be collected more efficiently. As a result, the lubrication performance is improved.

  As shown in FIGS. 4 to 6, the partition wall 36 is formed in a curved surface shape. Specifically, the partition wall 36 is formed in an arc shape that swells toward the second introduction part 52 side. The aspect in which the partition wall 36 is formed in an arc shape that swells toward the second introduction portion 52 corresponds to the “configuration in which the second introduction portion side has a convex curved surface” in the present invention.

  The first introduction portion 42 is provided on the front side (upper side in FIG. 6) in the scattering direction of the lubricating oil that is scraped up and scattered by the ring gear 9 in the introduction portion 30, as shown in FIGS. 4 and 6. 32, 34, a partition wall 36, and a bottom surface 44.

  As shown in FIGS. 4 to 6 and 8, the side wall 54 is disposed in parallel to the side wall 34 and separated from the side wall 32 (the left side in FIG. 5) by a predetermined distance. Extends along the direction. The side wall 54 is connected to one end of the partition wall 36. Thereby, between the side wall 34 and the side wall 54, the channel | path part 39 by which the both ends (up-down direction edge part of FIG. 6) of the extending direction of the side wall 54 was open | released is formed.

  As shown in FIG. 8, the bottom surface 58 is formed to be inclined downward from the side wall 54 side toward the side wall 32 side. Specifically, the height direction position of the bottom surface 58 on the side wall 54 side is formed at a position higher than the height direction position of the bottom surface 44 as shown in FIG. The position is formed at a height position substantially the same as the height direction position of the bottom surface 44.

  As shown in FIGS. 4 to 6, the flow path portion 60 has a longitudinal direction along a direction orthogonal to the introduction portion 30, and includes two side walls 62 and 64 and a bottom surface 66, and the longitudinal direction. The cross-sectional shape orthogonal to is formed in a substantially U shape. The end of the flow path portion 60 on the side connected to the side wall 32 of the partition wall 36 is disposed substantially at the center of the flow path width direction of the flow path portion 60 (the direction perpendicular to the longitudinal direction, the vertical direction in FIG. 6). As shown in FIG. As a result, the flow path portion 60 communicates with the first and second introduction portions 42 and 52 through the through openings 37 and 38.

  The flow path section 60 is connected so as to be orthogonal to the introduction section 30 and linearly extends from the introduction section 30. The bent flow path section 74 bends with respect to the straight flow path section 72. , And has a substantially J shape in plan view. The side wall 62 constitutes the inner side wall in the bending direction, and the side wall 64 constitutes the outer side wall in the bending direction. The bent flow path portion 74 is configured such that the flow path width becomes narrower toward the distal end portion, and is opened at the distal end.

  As shown in FIGS. 4 to 6, three openings 82, 84, 86 are formed in the side wall 62 in this order from the introduction part 30 side (left side in FIG. 6). The openings 82 and 84 are formed in a portion of the side wall 62 corresponding to the straight flow path portion 72, and the opening 86 is formed in a portion of the side wall 62 corresponding to the bent flow path portion 74. The opening 82 is formed from the side wall 62 to the bottom surface 66.

  Further, as shown in FIG. 4 to FIG. 6, the side wall 62 protrudes toward the front end of the portion corresponding to the bent flow path portion 74 so as to protrude toward the inside in the bending direction (lower side in FIG. 6). A path 88 is formed.

  The bottom surface 66 is configured to be inclined downward from the introduction portion 30 side (left side in FIG. 6) toward the tip portion side (bent flow channel portion 74 side, right side in FIG. 6). As shown in FIGS. 4 and 6, three rectifying ribs 92, 94, and 96 are formed on the bottom surface 66 so as to extend in the longitudinal direction of the flow path portion 60. The height of the rectifying ribs 92, 94, 96 is formed lower than the side walls 62, 64.

  As shown in FIG. 6, the rectifying rib 92 is formed closest to the side wall 62, one end thereof is disposed at a position corresponding to the substantially center between the openings 82 and 84, and extends substantially parallel to the side wall 62 therefrom. The other end is connected to the side wall 62 beyond the opening 84.

  As shown in FIG. 6, the rectifying rib 94 is formed on the side wall 64 side (upper side in FIG. 6) from the rectifying rib 92, and one end is substantially the same position as the rectifying rib 92, that is, at the substantially center between the openings 82 and 84. The other end is connected to the side wall 62 beyond the opening 86, arranged at a corresponding position, extending substantially parallel to the side wall 62 therefrom.

  The rectifying rib 96 is formed closest to the side wall 64, and one end thereof is connected to the side wall 64 at a position substantially the same as that of the rectifying ribs 92 and 94, that is, a position corresponding to substantially the center between the openings 82 and 84. The bent flow passage portion 74 extends obliquely with respect to the longitudinal direction of the straight flow passage portion 72 so that the other end is disposed at a position corresponding to the center of each of the flow passage width direction and the longitudinal direction.

  As shown in FIGS. 1 and 2, the oil garter 20 configured in this way has an extending direction of the introduction portion 30 at a position above the ring gear 9 and between the main shaft 4 and the rotation shaft of the ring gear 9. 9 is installed in the installation part 14b so as to be in a direction substantially along the tangential direction. Thereby, the flow path portion 60 is arranged so that the longitudinal direction of the straight flow path portion 72 and the axial direction of the input shaft 2 and the main shaft 4 are parallel, and the tip end portion of the bent flow path portion 74 is the input shaft. It arrange | positions so that it may face 2 side, and it arrange | positions so that the side wall 62 may become the input shaft 2 and the main shaft 4 side.

  Next, the operation of the transmission 1 configured as described above, in particular, the operation when the lubricating oil scraped up by the ring gear 9 is supplied to a portion requiring lubrication such as the transmission mechanism 6 will be described. When the ring gear 9 rotates with the operation of the transmission 1, the lubricating oil stored in the transmission case 10 is scraped up by the ring gear 9.

  The lubricating oil that has been scraped up is introduced into the introduction portion 30 of the oil garter 20 that is arranged so that the extending direction of the introduction portion 30 faces the direction along the tangential direction of the ring gear 9. Here, when the transmission 1 is operated at a low speed such as the first speed or the second speed, the rotational speed of the ring gear 9 is relatively low, and most of the lubricating oil scraped up by the ring gear 9 is obtained. Is introduced into the first introduction part 42 and collides with the partition wall 36 to change its direction.

  That is, when the rotational speed of the ring gear 9 is relatively low, most of the lubricating oil scraped up by the ring gear 9 is collected by the first introduction part 42 and passes through the through opening 37 from the first introduction part 42. It flows into the flow path part 60. Here, since the partition wall 36 is inclined so as to guide the lubricating oil collected in the first introduction part 42 to the flow path part 60, the lubricating oil does not stay in the first introduction part 42, It can be quickly introduced into the flow path section 60.

  In addition, since the partition wall 36 is formed in an arc shape that swells toward the second introduction portion 52 side, the flow direction of the lubricating oil can be smoothly changed to the through opening 37 side, so that the partition wall 36 is flat compared to the case of a flat surface. The lubricating oil can be guided to the flow path portion 60 more quickly.

  Since the bottom surface 44 of the first introduction part 42 has an upward inclined part 44a, it collides with the partition wall 36 and tries to reversely flow through the first introduction part 42 due to the reaction (what is the direction in which the lubricating oil is scattered)? The movement of the lubricating oil (which tends to flow in the opposite direction) can be suppressed, and guidance to the flow path portion 60 can be promoted. Thereby, lubricating oil can be guide | induced to the flow-path part 60 efficiently and rapidly. In addition, since it is the structure which only forms the bottom face 44 of the 1st introducing | transducing part 42 in the upward inclination, a structure is also simple.

  As shown in FIG. 9, the lubricating oil that has flowed into the flow path portion 60 flows out from the ends of the openings 84 and 86, the protruding flow path 88, and the bent flow path portion 74. The lubricating oil that has flowed out of the opening 84 is supplied onto the third speed driven gear G′3, and the meshing portion between the third speed driven gear G′3 and the third speed driven gear G3 and the third speed driven gear G′3. Lubricate. The lubricating oil that has flowed out of the opening 86 is supplied onto the fourth speed driven gear G′4 and lubricates the fourth speed driven gear G4 and the meshing portion between the fourth speed driven gear G4 and the fourth speed driven gear G′4. . Lubricating oil that has flowed out of the protruding flow path 88 is supplied onto the 6th speed drive gear G6, the meshing portion of the 6th speed drive gear G6 and the 6th speed drive gear G6 and the 6th speed driven gear G'6, and the 6th speed clutch gear. Lubricate etc.

  The lubricating oil that has flowed out from the tip of the bent flow passage 74 is supplied to an in-shaft oil passage (not shown) formed in the input shaft 2 through a flow passage (not shown) formed in the case body 12. The Lubricating oil supplied to an in-shaft oil passage (not shown) is supplied to a synchronization mechanism S or the like disposed on the input shaft 2 through a radial hole (not shown) formed in the input shaft 2.

  The bottom surface 66 of the flow channel portion 60 is configured to be inclined downward toward the downstream side (the bent flow channel portion 74 side), so that it is positioned far from the ring gear 9 (the tip of the bent flow channel portion 74). Part) can be supplied quickly and effectively. Further, since the flow path width is gradually narrowed as the bent flow path part 74 moves toward the tip, the flow rate of the lubricating oil can be increased, and the front end part (oil garter) of the bent flow path part 74 can be increased. The lubricating oil can be flowed effectively up to 20 tips.

  On the other hand, as the transmission 1 is operated at a high speed such as the third speed to the sixth speed, the rotational speed of the ring gear 9 becomes higher, and is scraped up by the ring gear 9 and captured by the first introduction portion 42. Part of the collected lubricating oil passes over the partition wall 36 and flows into the second introduction part 52. At this time, since the kinetic energy of the lubricating oil is reduced by the partition wall 36, the second introducing portion 52 can effectively collect the lubricating oil. Here, since the bottom surface 58 of the second introduction part 52 is configured to be inclined downward toward the through opening 38, the lubricating oil collected by the second introduction part 52 can be quickly passed through the through opening 38. It can be introduced into the channel part 60.

  That is, when the rotational speed of the ring gear 9 is high, the lubricating oil scooped up by the ring gear 9 is collected by both the first and second introduction parts 42 and 52 and flows through the through openings 37 and 38. Since it can be introduced into the portion 60, the lubricating oil scraped up by the ring gear 9 can be efficiently collected without waste. In this case as well, the upward inclined portion 44a of the bottom surface 44 of the first introduction portion 42 collides with the partition wall 36 and tries to flow backward through the first introduction portion 42 by the reaction (what is the lubricating oil scattering direction? The movement of the lubricating oil (which tries to flow in the opposite direction) can be effectively suppressed. Thereby, the lubricating oil can be efficiently guided to the flow path portion 60.

  Then, the lubricating oil that has flowed into the flow path portion 60 flows out from the ends of the openings 84 and 86, the protruding flow path 88, and the bent flow path portion 74 in the same manner as when the rotational speed of the ring gear 9 is low. The meshed portion of the driven gear G′3 and the third speed driven gear G3 and the third speed driven gear G′3, the fourth speed driven gear G′4, the fourth speed driven gear G4, and the fourth speed driven gear G′4 6-speed drive gear G6, 6-speed drive gear G6 and 6-speed driven gear G′6, 6-speed clutch gear, and in-shaft oil passage formed in the input shaft 2 ( (Not shown)).

  Note that the lubricating oil scraped up by the ring gear 9 and not exceeding the partition wall 36 and exceeding the partition wall 36 is formed on the inner wall surface of the clutch housing 14 as shown in FIG. It collides with the rib 14c, flows down along the rib 14c, and is collected by the second introduction part 52. Thereby, the lubricating oil scraped up by the ring gear 9 can be efficiently collected without waste and supplied to a portion requiring lubrication.

  Further, a part of the lubricating oil scraped up by the ring gear 9 and introduced into the introducing portion 30 is supplied to an in-shaft oil passage (not shown) formed in the main shaft 4 via a passage portion 39 as shown in FIG. The Lubricating oil supplied to an in-shaft oil passage (not shown) is supplied to a synchro mechanism S arranged on the main shaft 4 through a radial hole (not shown) formed in the main shaft 4.

  Further, the oil garter 20 according to the present embodiment is configured to collect the lubricating oil scraped up by the first speed driven gear G′1 in addition to the ring gear 9. The lubricating oil scraped up by the first speed driven gear G ′ 1 is taken into the straight flow path portion 72 through the opening 82. Thus, a sufficient oil supply amount can be ensured even at a low speed gear stage (for example, first speed or second speed) where the rotation speed of the ring gear 9 is low.

  According to the transmission 1 according to the present embodiment described above, the first introduction portion 42 and the second introduction portion are extended in the extending direction of the introduction portion 30 by the partition wall 36 in which the introduction portion 30 of the oil garter 20 is inclined in an arc shape. The first introduction part 42 is partitioned into a part 52, and an ascending inclined part 44a is formed on the bottom face 44 of the first introduction part 42 in a direction away from the partition wall 36, and the bottom face 58 of the second introduction part 52 is disposed on the side wall 54 side. Therefore, the lubricating oil scraped up by the ring gear 9 collides with the partition wall 36 and is guided to the through opening 37 side so that the flow path is formed. In addition to being able to be introduced into the part 60, the lubricating oil beyond the partition wall 36 can be introduced into the second introduction part 52 and introduced into the flow path part 60 from the through opening 38.

  Here, the flow of the lubricating oil, which collides with the partition wall 36 and tries to flow backward, is suppressed by the upward inclined portion 44 a, and the flow of the lubricating oil toward the through openings 37, 38 is caused by the upward inclined portion 44 a and the bottom surface 58. Promoted by down slope. As a result, regardless of the rotational speed of the ring gear 9, the lubricating oil can be efficiently collected and the collected lubricating oil can be quickly and effectively supplied to the portion requiring lubrication. As a result, the lubrication performance is improved.

  In the present embodiment, the partition wall 36 is formed in an arc shape that swells toward the second introduction portion 52 side, but the present invention is not limited to this. For example, the partition wall 36 may be formed in a polygonal shape that swells toward the second introduction portion 52, or may be formed in a planar shape.

  In the present embodiment, the oil garter 20 is installed above the ring gear 9 and at a position corresponding to the rotation axis of the main shaft 4 and the ring gear 9, but the lubricating oil scraped up by the ring gear 9 is supplied to the introduction portion 30. As long as it can be introduced, it may be arranged at any position.

  In the present embodiment, the rib 14 c is formed integrally with the inner wall surface of the clutch housing 14, but the rib 14 c may be separate from the clutch housing 14. In this case, the rib 14c may be attached and fixed to the clutch housing 14 by welding or bolting.

  In this embodiment, the present invention is applied to a manual transmission for an FF vehicle mounted on a front engine / front drive (FF) type vehicle, but for an FR vehicle mounted on a front engine / rear drive (FR) type vehicle. The present invention may be applied to a manual transmission.
