Description

  The present invention relates to a lubricating device, and more particularly to a lubricating device for supplying lubricating oil to a member to be lubricated such as a gear.

In an apparatus using mechanical parts, supply of lubricating oil may be required in order to suppress wear of the parts. For example, in a transmission having a large number of gears, a lubrication device is mounted in order to suppress gear wear. Specifically, the manual transmission of the vehicle includes a plurality of gears and a case that rotatably accommodates the gears. In order to lubricate the gear, lubricating oil is stored in the case to such an extent that the lower part of the gear is immersed. When the gear rotates, the gear teeth come into contact with the lubricating oil, and the meshing region between the gears is lubricated (see, for example, Patent Document 1).
JP 2005-76815 A

In the transmission described in Patent Document 1, an oil garter is provided in the case in order to collect the lubricating oil scraped up by the gear. The lubricating oil collected by the oil garter is guided to another gear by the oil garter.
However, when it is necessary to supply lubricating oil to a plurality of members to be lubricated, there is a possibility that the oil garter described above cannot sufficiently supply the lubricating oil to the members to be lubricated. In particular, when the member to be lubricated is disposed at a position farther than the gear for scooping up the lubricating oil, the oil garter may not sufficiently supply the lubricating oil to the far lubricated member.
Thus, there is a need for a lubricating device that can stably supply lubricating oil to a member to be lubricated.
The subject of this invention is providing the lubrication apparatus and transmission which can aim at stabilization of lubrication performance.

The lubricating device according to the present invention is a device for supplying lubricating oil to the first lubricated member and the second lubricated member. The lubrication apparatus includes a rotating member, a first guide portion, and a second guide portion. The rotating member can contact the lubricating oil. The first guiding portion has a first collecting portion that collects at least a part of the lubricating oil scraped up by the rotating member, and the lubricating oil collected by the first collecting portion is supplied to the first covered portion. Supply to lubrication member. The second guiding portion has a second collecting portion that collects at least a part of the lubricating oil scraped up by the rotating member, and the lubricating oil collected by the second collecting portion is used as the rotating member. Is supplied to a second lubricated member disposed at a position farther than the first lubricated member. The flow velocity of the lubricating oil collected by the second collecting portion is faster than the flow velocity of the lubricating oil collected by the first collecting portion at the same timing as the second collecting portion.
In this lubricating device, lubricating oil is supplied to the first lubricated member by the first guide member, and lubricating oil is supplied to the second lubricated member by the second guiding member. In this way, the lubricating oil is guided in a separate system with respect to the first and second lubricated members.

In addition, the flow velocity of the lubricating oil collected by the second collecting portion is faster than the flow velocity of the lubricating oil collected by the first collecting portion at the same timing as the second collecting portion. For this reason, the lubricating oil collected by the second collecting portion flows farther than the lubricating oil collected by the first collecting portion.
As described above, in this lubricating device, the lubricating oil can be sufficiently supplied not only to the first lubricated member but also to the second lubricated member disposed farther than the first lubricated member, and the lubricating performance Can be stabilized.

  As described above, the lubrication apparatus according to the present invention and the transmission including the lubrication apparatus can stabilize the lubrication performance.

(1) Oil garter 6
As shown in FIGS. 1 to 5, the oil garter 6 uses the counter drive gear G17, the second speed counter gear G12 and the first speed counter gear G12 to remove the lubricating oil scraped up by the third speed counter gear G13 and the second synchronization mechanism S2. It is a member for guiding to the speed counter gear G11 and is arranged on the side of the counter shaft 4. The rear end of the oil garter 6 is fixed to, for example, the adapter plate 23. The oil garter 6 is disposed on the side where the counter drive gear G17 scoops up the lubricating oil with respect to the rotation axis A2 (the side on which the outer peripheral portion of the counter drive gear G17 moves generally upward).

As shown in FIGS. 6 to 14, the oil garter 6 is formed by a receiving member B and a lid member C, and includes a first guiding portion 61, a second guiding portion 62, and a third guiding portion 63. Have. The receiving member B and the lid member C are made of, for example, resin and are integrally formed. The lid member C is attached to the receiving member B.
The receiving member B has a receiving member main body B1, a bending portion B2, and a partition plate B3. The lid member C has a bottom plate C1 and a side wall C2. The first guiding portion 61, the second guiding portion 62, and the third guiding portion 63 are formed by these portions. The first guide portion 61 and the second guide portion 62 are generally sealed by the lid member C. Here, the “substantially sealed” state means a state in which the lubricating oil hardly overflows from the inlet to the outlet, and the state other than the lubricating oil inlet and outlet is completely sealed ( For example, in addition to the state where the joint between the receiving member B and the lid member C is completely sealed), the state where the lubricating oil leaks from the joint between the receiving member B and the lid member C to the extent that a desired lubricating performance can be ensured ( For example, a state in which a gap is formed between the receiving member B and the lid member C is also included.

1) First guide part The first guide part 61 is a part for collecting at least a part of the lubricating oil scraped up by the third speed counter gear G13 and supplying it to the second speed counter gear G12. It has the 1 collection part 61a, the 1st intermediate part 61b, and the 1st discharge part 61c.
The first collection part 61a is a part for collecting at least a part of the lubricating oil scooped up by the third speed counter gear G13, and the radial direction of the third speed counter gear G13 and the second synchronization mechanism S2 Arranged outside. The first collection portion 61a (more specifically, the first opening 61e) is provided so as to face the direction in which the third speed counter gear G13 scoops up the lubricating oil. In this embodiment, since the 1st collection part 61a is arrange | positioned in the substantially same height as rotating shaft A2, the 1st opening 61e of the 1st collection part 61a has faced the downward direction substantially. At least when the vehicle is traveling at the first speed and the second speed, the first collecting portion 61a is disposed at a position where it is not immersed in the lubricating oil.

In the 1st collection part 61a, the flow direction of lubricating oil is changed from upper direction to the axial direction front. Specifically, the 1st collection part 61a is formed of the receiving member main body B1, the curved part B2, and the partition plate B3. The curved portion B2 is a plate-like portion that is curved so that the flow direction of the lubricating oil can be changed in the axial direction. Thereby, lubricating oil flows smoothly from the 1st collection part 61a to the 1st intermediate part 61b. Thus, the direction change part D1 which changes the flow direction of lubricating oil is implement | achieved by the 1st collection part 61a.
The 1st intermediate part 61b is a part which connects the 1st collection part 61a and the 1st discharge part 61c. Specifically, the first intermediate portion 61b is formed by the receiving member main body B1, the curved portion B2, and the bottom plate C1. The lubricating oil collected by the first collecting part 61a flows into the first discharge part 61c via the first intermediate part 61b.

The first discharge part 61c is a part for discharging the lubricating oil collected by the first collecting part 61a toward the second speed counter gear G12. Specifically, the first discharge part 61c has an inclined part 61d that extends obliquely upward so as to approach the third speed counter gear G13.
The first discharge portion 61c protrudes from the first intermediate portion 61b toward the counter drive gear G17, and is disposed close to the second speed counter gear G12. Here, “the first discharge portion 61c is close to the second speed counter gear G12” means that the first discharge portion 61c is separated from the second speed counter gear G12 to such an extent that a desired lubricating performance can be secured. It also includes the state. As a state where the first discharge portion 61c is close to the second speed counter gear G12, for example, the shortest dimension between the tip of the first discharge portion 61c and the tip of the teeth of the second speed counter gear G12 is the first dimension. A state that is approximately the same as or smaller than the tooth height of the second-speed counter gear G12 is conceivable. Lubricating oil is discharged toward the front in the rotational direction of the second speed counter gear G12 by the first discharge portion 61c. That is, the direction change part D3 which changes the flow direction of lubricating oil is implement | achieved by the 1st discharge part 61c.

The first discharge part 61c further includes a first rear side wall part 61f and a first front side wall part 61e. The first rear side wall portion 61f is a plate-like portion disposed on the rear side of the inclined portion 61d, and extends toward the second speed counter gear G12. The first front side wall portion 61e is a plate-like portion disposed on the front side of the inclined portion 61d, and extends toward the second speed counter gear G12. Further, the first rear side wall 61f extends toward the second speed counter gear G12 so as to approach the first front side wall 61e. That is, the flow path is slightly narrowed by the first discharge part 61c. The inclined portion 61d, the first rear side wall portion 61f, and the first front side wall portion 61e facilitate the discharge of the lubricating oil toward the second speed counter gear G12.
With these configurations, the first flow path P1 for guiding the lubricating oil scraped up by the third speed counter gear G13 to the second speed counter gear G12 is formed.

2) Second guiding portion The second guiding portion 62 is a portion for collecting at least a part of the lubricating oil scraped up by the third speed counter gear G13 and supplying it to the second speed counter gear G12. It has the 2 collection part 62a, the 2nd intermediate part 62b, the 2nd discharge part 62c, and the extension part 64. As shown in FIG.
The second collection part 62a is a part for collecting at least a part of the lubricating oil scraped up by the third speed counter gear G13, and is in the radial direction of the third speed counter gear G13 and the second synchronization mechanism S2. Arranged outside. Similar to the first collecting portion 61a, the second collecting portion 62a is provided so that the third speed counter gear G13 faces the direction of scooping up the lubricating oil. In this embodiment, since the 1st collection part 61a is arrange | positioned in the substantially same height as rotating shaft A2, the 2nd opening 62e of the 2nd collection part 62a has faced the downward direction substantially. The second collecting portion 62a is disposed at a position where it is not immersed in the lubricating oil at least when the vehicle is running at the first speed and the second speed. The 1st collection part 61a and the 2nd collection part 62a are arrange | positioned so that it may rank in a radial direction. The 2nd collection part 62a is arrange | positioned in the radial direction outer side of the 1st collection part 61a.

In the second collection part 62a, the flow direction of the lubricating oil is changed from the upper side to the front side in the axial direction. Specifically, the second collecting portion 62a is formed by the receiving member main body B1, the curved portion B2, and the partition plate B3. Thereby, lubricating oil flows smoothly from the 2nd collection part 62a to the 2nd intermediate part 62b. Thus, the direction change part D2 which changes the flow direction of lubricating oil is implement | achieved by the 2nd collection part 62a.
The 2nd intermediate part 62b is a part which connects the 2nd collection part 62a and the 2nd discharge part 62c. Specifically, the second intermediate portion 62b is formed by the receiving member main body B1, the curved portion B2, and the bottom plate C1. The lubricating oil collected by the second collection part 62a flows into the second discharge part 62c via the second intermediate part 62b.
The second discharge part 62c is a part for discharging the lubricating oil collected by the second collection part 62a toward the second speed counter gear G12. Specifically, the second discharge part 62c protrudes from the second intermediate part 62b toward the second speed counter gear G12, and is disposed close to the second speed counter gear G12. Unlike the first discharge part 61c, the second discharge part 62c protrudes substantially horizontally.

Specifically, the second discharge part 62c has a bottom plate 62d, a second rear side wall part 62f, and a second front side wall part 62e. The bottom plate 62d protrudes toward the counter drive gear G17. The second rear side wall portion 62f is a plate-like portion disposed on the rear side of the bottom plate 62d, and extends toward the counter drive gear G17. The second front side wall 62e is a plate-like portion disposed on the front side of the bottom plate 62d, and extends toward the counter drive gear G17. For example, the second rear side wall 62f is formed integrally with a first rear side rib 64c (described later), and the second front side wall 62e is formed integrally with a first front side rib 64d (described later). Lubricating oil is easily discharged toward the counter drive gear G17 by the second rear side wall 62f and the second front side wall 62e.
The second guide portion 62 is disposed at a position farther in the radial direction than the first guide portion 61 with respect to the third speed counter gear G13. The second guiding portion 62 has a portion Q where the flow path cross-sectional area gradually decreases between the second collecting portion 62a and the counter drive gear G17 (see FIG. 13). More specifically, since a part of the side wall of the receiving member main body B1 is inclined, the dimension between the partition plate B3 and the side wall of the receiving member main body B1 is gradually reduced (FIGS. 6 and 9). (See FIG. 11).

With these configurations, the second flow path P2 that guides the lubricating oil scraped up by the third speed counter gear G13 to the counter drive gear G17 is formed. Details of the extension 64 will be described later.
3) 3rd guidance part The 3rd guidance part 63 is arranged above the 1st collection part 61a and the 2nd collection part 62a, and is formed of bottom plate C1 and side wall part C2 of lid member C. The third guiding portion 63 collects the lubricating oil dropped from the upper part of the case 2 and supplies it to the first speed counter gear G11. Specifically, the 3rd guidance part 63 has the 3rd collection part 63a and the 3rd discharge part 63c.
The third collecting part 63 a is a part that collects the lubricating oil dropped from the upper part of the case 2. The third discharge part 63c is a part for supplying the lubricating oil collected by the third collecting part 63a to the first speed counter gear G11. The 3rd discharge part 63c protrudes toward the 1st speed counter gear G11 from the 3rd collection part 63a, and is arranged near the 1st speed counter gear G11. The third discharge part 63c protrudes substantially horizontally from the third collection part 63a.

The third collection portion 63a has an inclined portion 63d that is inclined with respect to the horizontal plane so as to descend toward the third discharge portion 63c. The inclined portion 63d makes it easier for the lubricating oil to flow toward the third discharge portion 63c, and the lubricating oil is easily discharged from the third discharge portion 63c.
4) Extension part Here, the detail of the extension part 64 of the 2nd guidance | induction part 62 is demonstrated.
The extension portion 64 includes a first extension portion 64a extending downward from the end portion of the second discharge portion 62c along the outer peripheral portion of the counter drive gear G17, and an end portion of the first extension portion 64a so as to be separated from the counter drive gear G17. And a second extension portion 64b extending downward.
The dimension of the gap between the first extension portion 64a and the counter drive gear G17 is substantially constant. The 1st extension part 64a has the 1st main part 64e, the 1st back side rib 64c, and the 1st front side rib 64d. The first main body 64e is disposed so as to face the counter drive gear G17 in the radial direction.

The first rear rib 64c is disposed at the rear end of the first main body portion 64e, and extends from the first main body portion 64e toward the inside in the radial direction of the counter drive gear G17. The first rear rib 64c extends in the rotational direction along the outer periphery of the counter drive gear G17 over the entire length of the first main body 64e. The first rear rib 64c is disposed on the rear side with respect to the counter drive gear G17. In the present embodiment, the height of the first rear side rib 64c is higher than the height of the first front side rib 64d.
The first front rib 64d is disposed at the front end of the first main body 64e, and extends radially inward from the first main body 64e to the counter drive gear G17. The first front rib 64d extends in the rotational direction along the outer periphery of the counter drive gear G17 over the entire length of the first main body 64e.

The second extension portion 64b includes a second main body portion 64f, a second rear side rib 64g, and a second front side rib 64h. The second body portion 64f extends obliquely downward from the end portion of the first extension portion 64a so as to be gradually separated from the third speed counter gear G13.
The second rear side rib 64g is disposed at the rear side end of the second main body part 64f, and extends from the second main body part 64f toward the inside in the radial direction of the counter drive gear G17. The second rear rib 64g extends in the rotational direction along the outer periphery of the counter drive gear G17 over the entire length of the second main body 64f. The second rear rib 64g is disposed on the rear side with respect to the counter drive gear G17. For example, the second rear side rib 64g is integrally formed with the first rear side rib 64c.
The second front rib 64h is disposed at the front end of the second main body 64f, and extends radially inward from the second main body 64f to the counter drive gear G17. The second front rib 64h extends in the rotational direction along the outer periphery of the counter drive gear G17 over the entire length of the second main body 64f. For example, the second front rib 64h is integrally formed with the first front rib 64d.

Furthermore, the extension part 64 has three ribs 64i. The rib 64i is disposed between the first rear side rib 64c and the first front side rib 64d, and between the second rear side rib 64g and the second front side rib 64h. The second extending portion 64b extends in the rotational direction over the entire length. The height of the rib 64i is substantially the same as the height of the first front rib 64d. The first rear rib 64c, the first front rib 64d, and the rib 64i have a function of increasing the strength of the first main body portion 64e and, in addition, rotate lubricating oil flowing between the counter drive gear G17 and the extension portion 64 in the rotation direction. It also has the function of rectifying.
(2) Garter Plate The garter plate 7 (an example of the fourth guide portion) is a sheet metal member disposed at the lower portion of the counter shaft 4 and includes a plate body 71 and a guide portion 72.

The plate body 71 is a main part of the garter plate 7 and is disposed between the lower portion of the first case 21 and each gear. The guide portion 72 is formed integrally with the plate body 71 and is disposed on the radially outer side of the third speed counter gear G13.
The plate main body 71 is a sheet metal member disposed so as to cover the lower half of the gear supported by the counter shaft 4 and the synchro mechanism. For example, the third speed counter gear G13 and the second synchronization mechanism S2 are opposed to the plate body 71 in the radial direction. The space on the radially outer side of the third speed counter gear G13 and the second synchronization mechanism S2 is narrowed by the plate body 71. Accordingly, the lubricating oil is easily scraped up by the third speed counter gear G13 and the second synchronization mechanism S2.
The guide part 72 is disposed around the second collection part 62a, and guides the lubricating oil scraped up by the third speed counter gear G13 together with the plate body 71 to the second collection part 62a. More specifically, the guide part 72 has a pair of side wall parts 72a. The side wall 72a is disposed at a position shifted axially forward and rearward from the third speed counter gear G13, and extends radially outward from the plate body 71. In other words, the guide portion 72 protrudes radially outward from the plate body 71 from the lower side to the side of the third speed counter gear G13. For this reason, as shown in FIG. 16, the lubricating oil is easily scraped up by the plate body 71 from below the counter shaft 4 to the vicinity of the second trapping portion 62a, and in the vicinity of the second trapping portion 62a. The lubricating oil thus produced is guided along the guide portion 72 to the second collection portion 62a.

Thus, the lubricating oil is easily guided to the second collection part 62a by the garter plate 7 as the third speed counter gear G13 rotates, and the collection efficiency in the second collection part 62a is increased. In particular, even if axial acceleration acts on the lubricating oil, since the movement of the lubricating oil in the axial direction is restricted by the pair of side wall portions 72a in the guide portion 72, the second even during acceleration and deceleration of the vehicle. The collection efficiency of the collection unit 62a is likely to be stable.
<Transmission operation>
The operation of the transmission 1 will be described with reference to FIG.
For example, during the first speed traveling, the first speed main gear G1 and the main shaft 8 are connected by the third synchronization mechanism S3. The power transmitted to the input shaft 3 is transmitted to the counter shaft 4 via the main drive gear G7 and the counter drive gear G17. The power transmitted to the countershaft 4 is transmitted to the main shaft 8 via the first speed counter gear G11 and the first speed main gear G1. At this time, the main shaft 8 rotates at a rotational speed corresponding to the gear ratio between the first speed main gear G1 and the first speed counter gear G11.

Further, during the second speed traveling, the second speed main gear G2 and the main shaft 8 are connected by the third synchronization mechanism S3. The power transmitted to the input shaft 3 is transmitted to the counter shaft 4 via the main drive gear G7 and the counter drive gear G17. The power transmitted to the countershaft 4 is transmitted to the main shaft 8 via the second speed counter gear G12 and the second speed main gear G2. At this time, the main shaft 8 rotates at a rotational speed corresponding to the gear ratio between the second speed main gear G2 and the second speed counter gear G12.
Since the main shaft 8 always rotates during traveling at the first speed and the second speed, the third speed main gear G3 and the third speed counter gear G13 are also rotating. For this reason, during traveling in the first speed and the second speed, the lubricating oil accumulated in the lower portion of the case 2 is scraped up by the third speed counter gear G13.

<Lubricant behavior>
When the vehicle is traveling at the first speed, since the third speed counter gear G13 and the second sync mechanism S2 are rotating, the lubricating oil is scraped up by the third speed counter gear G13 and the second sync mechanism S2. . The lubricating oil scooped up by the third speed counter gear G13 is guided to the second speed counter gear G12 and the counter drive gear G17 by the first guide portion 61 and the second guide portion 62. Specifically, the lubricating oil scraped up by the third speed counter gear G13 flows into the first collection unit 61a and the second collection unit 62a.
The lubricating oil that has flowed into the first collecting portion 61a is guided forward in the axial direction by the curved portion B2, and is discharged from the first discharge portion 61c toward the second speed counter gear G12 via the first intermediate portion 61b. . Since the inclined portion 61d extends obliquely upward, the lubricating oil is discharged obliquely upward from the first discharge portion 61c. As a result, the discharged lubricating oil flows along the outer peripheral portion of the second speed counter gear G12.

  The lubricating oil that has flowed into the second collection part 62a changes its flow direction forward in the axial direction by the curved part B2, is guided to the second discharge part 62c by the second intermediate part 62b, and is driven from the second discharge part 62c to the counter drive gear. It is discharged toward G17. Since the first extension portion 64a of the extension portion 64 is provided along the outer peripheral portion of the counter drive gear G17, the lubricating oil discharged from the second discharge portion 62c is between the counter drive gear G17 and the first extension portion 64a. It flows in between and is scraped up by the counter drive gear G17. As a result, the lubricating oil discharged from the second discharge portion 62c is likely to adhere to the counter drive gear G17, and the lubricating efficiency of the counter drive gear G17 is increased. Since the lubricating oil scraped up by the third speed counter gear G13 by the guide part 72 of the garter plate 7 is guided to the second collection part 62a, the collection efficiency of the second collection part 62a is increased.

Since the positions of collecting the lubricating oil in the first collecting portion 61a and the second collecting portion 62a are different, the flow rates of the lubricating oil in the first collecting portion 61a and the second collecting portion 62a are also different. Specifically, the flow rate of the lubricating oil scraped up by the third-speed counter gear G13 is mainly at the outer side in the radial direction farther from the rotational axis A2 than the inner side in the radial direction near the rotational axis A2 due to the centrifugal force. Get faster. For this reason, the flow velocity of the lubricating oil in the second collecting portion 62a disposed on the radially outer side than the first collecting portion 61a is faster than the flow velocity of the lubricating oil in the first collecting portion 61a. Thereby, even if the second discharge part 62c is arranged farther than the first discharge part 61c with respect to the third speed counter gear G13, the lubricating oil collected by the second collection part 62a is second discharged. It can flow reliably to the part 62c.
On the other hand, the lubricating oil that has not been collected by the first collection unit 61 a and the second collection unit 62 a returns to the lower part of the case 2 or adheres to the upper part of the case 2. A part of the lubricating oil adhering to the upper part of the case 2 falls into the third collection part 63 a of the third guide part 63. The lubricating oil collected by the third collecting portion 63a is discharged from the third discharging portion 63c toward the first speed counter gear G11. This increases the lubrication efficiency of the first speed counter gear G11.

<Features>
The features of the lubricating device L and the transmission 1 are as follows.
(1)
In the lubricating device L, the second guide gear 61 is supplied with lubricating oil by the first guide 61, and the counter drive gear G17 is supplied with lubricant by the second guide 62. Thus, the lubricating oil is guided in a separate system with respect to the second speed counter gear G12 and the counter drive gear G17.
In addition, the flow velocity of the lubricating oil collected by the second collecting portion 62a is faster than the flow velocity of the lubricating oil collected by the first collecting portion 61a at the same timing as the second collecting portion 62a. For this reason, the lubricating oil collected by the second collecting portion 62a flows farther than the lubricating oil collected by the first collecting portion 61a.

Therefore, in the lubricating device L, the lubricating oil can be sufficiently supplied not only to the second speed counter gear G12 but also to the counter drive gear G17 disposed farther than the second speed counter gear G12. The performance can be stabilized.
(2)
Since the first collecting portion 61a and the second collecting portion 62a are disposed radially outside the third speed counter gear G13 and the second synchro mechanism S2, the lubricating oil scooped up by the third speed counter gear G13 However, it is easy to flow into the 1st collection part 61a and the 2nd collection part 62a. For this reason, the collection efficiency of lubricating oil becomes high, and more lubricating oil can be supplied to the 2nd speed counter gear G12 and the counter drive gear G17.
Moreover, since the 1st collection part 61a and the 2nd collection part 62a are arrange | positioned in the radial direction outer side of the 3rd speed counter gear G13 and 2nd synchro mechanism S2, the member for scooping up lubricating oil is provided separately. There is no need. For this reason, in this lubrication apparatus L, it is possible to stabilize the lubrication performance while preventing an increase in manufacturing cost.

(3)
Since the second collection part 62a is arranged at a position farther in the radial direction than the first collection part 61a with respect to the third speed counter gear G13, the flow rate of the lubricating oil flowing into the first collection part 61a The flow rate of the lubricating oil flowing into the second collection part 62a becomes faster. That is, it can be said that the lubricating oil flowing into the second collection part 62a has more kinetic energy. Thereby, the lubricating oil can be guided further by the second guiding portion 62, and the lubricating oil can be reliably guided to the counter drive gear G17.
(4)
The second guide portion 62 is disposed at a position farther in the radial direction than the first guide portion 61 with respect to the third speed counter gear G13. Specifically, the second intermediate portion 62b is disposed at a position farther in the radial direction than the first intermediate portion 61b with respect to the third speed counter gear G13. For this reason, the structure which guides lubricating oil to the counter drive gear G17 arrange | positioned far with respect to the 3rd-speed counter gear G13 can be simplified.

(5)
Since the 1st induction | guidance | derivation part 61 has the 1st intermediate part 61b, the lubricating oil collected by the 1st collection part 61a can be reliably guide | induced to the 1st discharge part 61c. Since the 2nd guide part 62 has the 2nd middle part 62b, the lubricating oil collected by the 2nd collection part 62a can be certainly guided to the 2nd discharge part 62c. With these configurations, the lubricating oil can be reliably supplied to the second speed counter gear G12 and the counter drive gear G17.
In particular, since the first guiding portion 61 is generally sealed, the lubricating oil is guided to the first discharging portion 61c with almost no overflow. The second guiding part 62 is the same as the first guiding part 61. For this reason, the lubricating oil collected by the 1st collection part 61a and the 2nd collection part 62a is reliably guide | induced to the 1st discharge part 61c and the 2nd discharge part 62c.

(6)
Since the first collecting portion 61a and the second collecting portion 62a have the first opening 61e and the second opening 62e provided so as to face the direction in which the third speed counter gear G13 scoops up the lubricating oil. The lubricating oil can easily flow into the first collecting portion 61a and the second collecting portion 62a, and more lubricating oil can be collected.
(7)
Since the first collecting portion 61a and the second collecting portion 62a are arranged so as to be aligned in the radial direction, the lubricating oil scooped up by the third speed counter gear G13 is retained in the first collecting portion 61a and the second collecting portion. It becomes easy to flow into one side of the collection part 62a, and the collection efficiency of lubricating oil increases.
(8)
Direction changing portions D1 and D2 that change the flow direction of the lubricating oil are realized by the first collecting portion 61a and the second collecting portion 62a. Specifically, the first collecting portion 61a and the second collecting portion 62a change the flow direction of the lubricating oil scraped up by the third speed counter gear G13 to the axial direction of the third speed counter gear G13. For this reason, the lubricating oil can be guided in the axial direction using the momentum of the lubricating oil scraped up by the third speed counter gear G13, and the lubricating oil can be reliably supplied to the second speed counter gear G12 and the counter drive gear G17. Can supply.

Further, since the first discharge part 61c and the second discharge part 62c change the flow direction of the lubricating oil so as to go to the second speed counter gear G12 and the counter drive gear G17, the first intermediate part 61b and the second intermediate part 62b Smoothly flows into the second speed counter gear G12 and the counter drive gear G17.
(9)
A direction changing portion D3 that changes the flow direction of the lubricating oil is realized by the first discharge portion 61c. Specifically, the first discharge portion 61c has a shape in which the lubricating oil is discharged toward the front in the rotation direction of the second speed counter gear G12. More specifically, the first discharge portion 61c has an inclined portion 61d extending obliquely upward so as to approach the second speed counter gear G12. By the inclined portion 61d, the lubricating oil is discharged toward the front in the rotational direction of the second speed counter gear G12. Thereby, the lubricating oil is discharged along the outer peripheral portion of the second speed counter gear G12, and the lubricating oil can be prevented from colliding with the second speed counter gear G12 and being scattered. That is, the lubrication efficiency of the second speed counter gear G12 can be increased.

(10)
In a state where the first collection unit 61a and the second collection unit 62a are immersed in the lubricating oil, the lubricating oil is difficult to flow into the first collection unit 61a and the second collection unit 62a.
However, in this lubricating device L, at the time of traveling at the first speed and the second speed, the first collection part 61a and the second collection part 62a are arranged at positions where they are not immersed in the lubricating oil. The lubricating oil scraped up by the counter gear G13 can be collected effectively.
(11)
Since the second guiding portion 62 has a portion Q provided between the second collecting portion 62a and the counter drive gear G17 and the flow passage cross-sectional area gradually decreases, it is possible to suppress a decrease in the flow velocity of the lubricating oil, Lubricating oil can be sent further.

(12)
The counter drive gear G17 is disposed at a position farthest in the axial direction with respect to the third speed counter gear G13 as compared to the other gears. That is, the counter drive gear G17 is disposed on the forefront side in the gear train. For this reason, even if the lubricating oil is biased backward in the case 2 when the vehicle is running and the counter drive gear G17 is not immersed in the lubricating oil, the lubricating oil is reliably supplied to the counter drive gear G17 by the second guide portion 62. it can.
(13)
A part of the lubricating oil scraped up by the third speed counter gear G13 is not collected by the first collecting part 61a and the second collecting part 62a and adheres to the side wall or the upper part of the case 2. Since the third guiding part 63 is disposed above the first collecting part 61a and the second collecting part 62a, the lubricating oil dripping from the upper part of the case 2 is easily collected by the third guiding part 63. In particular, the amount of the lubricating oil dripping above the first collection part 61a and the second collection part 62a is relatively large. For this reason, the lubricating oil collected by the third guiding portion 63 is supplied to the first speed counter gear G11.

Thus, by providing the 3rd guidance | induction part 63, the lubricating oil in a case can be efficiently utilized with a compact structure.
(14)
Since the third guiding portion 63 has the bottom plate C1 used as a part of the first and second guiding portions 62, parts can be shared and the structure can be simplified.
(15)
The lubricating oil scooped up by the third speed counter gear G13 and the second synchronization mechanism S2 by the garter plate 7 is easily guided to the second collecting portion 62a. For this reason, the amount of the lubricating oil collected by the second collecting portion 62a increases, and the amount of the lubricating oil supplied to the counter drive gear G17 disposed far away can be increased. That is, the collection efficiency in the 2nd collection part 62a can be improved.

In particular, even if axial acceleration acts on the lubricating oil, since the movement of the lubricating oil in the axial direction is restricted by the pair of side wall portions 72a in the guide portion 72, the second even during acceleration and deceleration of the vehicle. The collection efficiency of the collection unit 62a is likely to be stable.
(16)
In the lubricating device L, the second discharge portion 62c of the second guide portion 62 protrudes toward the counter drive gear G17 and is disposed close to the counter drive gear G17. Therefore, the lubrication discharged from the second discharge portion 62c is performed. The oil easily comes into contact with the counter drive gear G17, and the lubricating oil does not easily fall downward from between the counter drive gear G17 and the second discharge portion 62c. Thereby, the lubrication efficiency of the counter drive gear G17 can be increased, and the lubrication performance can be enhanced.

(17)
Since the second guide portion 62 has the first extension portion 64a, the lubricating oil discharged from the second discharge portion 62c is not allowed to fall from between the second discharge portion 62c and the counter drive gear G17. 1 is received by the extension portion 64a and scraped up to the counter drive gear G17. Thereby, lubrication performance can be further improved.
(18)
Since the gap dimension between the first extension 64a and the counter drive gear G17 is substantially constant, even if the lubricant flows between the first extension 64a and the counter drive gear G17, the counter drive gear G17 causes the lubricant to flow. Is easily scraped.
(19)
Since the second guide portion 62 has a second extension portion 64b extending downward from the end of the first extension portion 64a so as to be separated from the counter drive gear G17, the lubricating oil around the counter drive gear G17 is counter-driven. It becomes easy to flow between the gear G17 and the second extension portion 64b. Thereby, the lubrication efficiency of the counter drive gear G17 further increases.

(20)
The first rear side rib 64c of the first extension part 64a prevents the lubricating oil between the first extension part 64a and the counter drive gear G17 from flowing backward. Further, the second rear side rib 64g of the second extension part 64b prevents the lubricating oil between the second extension part 64b and the counter drive gear G17 from flowing backward. Thereby, the lubrication efficiency of the counter drive gear G17 further increases.
Further, when the vehicle is accelerating and a backward acceleration acts on the lubricating oil, the lubricating oil between the first extension portion 64a and the counter drive gear G17 flows backward, and the first rear rib 64c. Is effectively suppressed. Similarly, in the case of the second extension part 64b, the second rear side rib 64g effectively suppresses the lubricating oil between the second extension part 64b and the counter drive gear G17 from flowing backward.

In addition, when the vehicle accelerates, when the backward acceleration acts on the lubricating oil, the second rear side wall portion 62f effectively suppresses the lubricating oil discharged from the second discharge portion 62c from flowing backward. Is done.
(21)
The first front side rib 64d of the first extension part 64a prevents the lubricating oil between the first extension part 64a and the counter drive gear G17 from flowing forward. Further, the second front side rib 64h of the second extension part 64b prevents the lubricating oil between the second extension part 64b and the counter drive gear G17 from flowing forward. Thereby, the lubrication efficiency of the counter drive gear G17 further increases.
Further, when forward acceleration acts on the lubricating oil when the vehicle stops, the lubricating oil between the first extension 64a and the counter drive gear G17 flows out to the front side. Is effectively suppressed. Similarly, in the case of the second extension 64b, the second front rib 64h effectively suppresses the lubricating oil between the second extension 64b and the counter drive gear G17 from flowing forward.

In addition, when the vehicle accelerates and the backward acceleration acts on the lubricating oil, the front side wall portion 62e effectively suppresses the lubricating oil discharged from the second discharge portion 62c from flowing forward. .
(22)
Since the first rear rib 64c and the first front rib 64d extend along the outer peripheral portion of the counter drive gear G17 over the entire length of the first main body 64e, the gap between the first extension 64a and the counter drive gear G17 It is easy to suppress the lubricating oil from flowing out of the first extension portion 64a, and the lubricating efficiency of the counter drive gear G17 can be increased.
(23)
The second guide portion 62 is disposed on the side on which the outer peripheral portion of the counter drive gear G17 moves substantially upward with respect to the rotation center of the counter drive gear G17 and vertically above the rotation center of the counter drive gear G17. Yes. For this reason, the region to which the lubricating oil is supplied and the region to be lubricated (portion where the counter drive gear G17 and the main drive gear G7 mesh) are close to each other, and the lubricating oil is easily supplied to the region to be lubricated. That is, the lubrication device L can stabilize the lubrication performance.

(24)
A direction changing portion D3 that changes the flow direction of the lubricating oil is realized by the first discharge portion 61c. Specifically, the first discharge portion 61c has an inclined portion 61d that extends obliquely upward so as to approach the counter drive gear G17. For this reason, the lubricating oil is discharged obliquely upward by the inclined portion 61d. As a result, the lubricating oil is discharged so as to substantially follow the outer peripheral portion of the second speed counter gear G12. Thereby, it can suppress that lubricating oil collides with 2nd speed counter gear G12, and is scattered, and can improve the lubrication efficiency of 2nd speed counter gear G12.
(25)
Since the oil garter 6 has the extension portion 64 disposed on the outer side in the radial direction of the counter drive gear G17, the lubricating oil is conveyed using the space between the plurality of teeth formed in the counter drive gear G17. be able to. Thereby, the lubrication efficiency of the counter drive gear G17 can be increased.

(26)
As described above, since the transmission 1 is equipped with the lubrication device L, the lubrication performance can be improved.
<Other embodiments>
The specific configuration of the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the invention.
In addition, about the structure which has the function substantially the same as the above-mentioned embodiment, the same code | symbol is used and detailed description is abbreviate | omitted.
(A)
The shapes of the oil garter 6 and the garter plate 7 are not limited to the above-described embodiment. For example, the oil garter 6 may be integrally formed instead of the two members of the receiving member B and the lid member C. That is, the first guide portion 61 may be integrally formed, the second guide portion 62 may be integrally formed, or the first guide portion 61 and the second guide portion 62 may be integrally formed. Good.

On the contrary, the 1st guidance part 61, the 2nd guidance part 62, and the 3rd guidance part 63 may be formed by another member. Furthermore, the garter plate 7 and the oil garter 6 may be integrally formed, or only the guide portion 72 may be integrally formed with the oil garter 6.
(B)
Although the 1st collection part 61a and the 2nd collection part 62a are arranged along with the radial direction, if it is a position which can collect lubricating oil, the 1st collection part 61a and the 2nd collection part 62a The position may be shifted in the vertical direction or the axial direction (for example, the longitudinal direction of the vehicle).
For example, as shown in FIG. 17, the first collection unit 161a (corresponding to the first collection unit 61a described above) is disposed above the second collection unit 162a (corresponding to the second collection unit 62a described above). May be. In this case, the first oil garter 106 having the first collection part 161a and the second oil garter 107 having the second collection part 162a are provided separately. The first oil garter 106 is disposed above the second oil garter 107. In FIG. 17, the first oil gutter 106 and the second oil gutter 107 are schematically drawn.

The first oil garter 106 is formed with a first flow path P11 (corresponding to the first flow path P1 described above), and the lubricating oil collected by the first collecting portion 161a is transferred to the second speed counter gear G12. It is discharged from the first discharge portion 161c. The second oil garter 107 is formed with a second flow path P12 (corresponding to the second flow path P2 described above), and the lubricating oil collected by the second collection portion 162a is directed toward the counter drive gear G17. It is discharged from the second discharge part 162c. Even with such a configuration, it is possible to improve the lubrication performance as in the above-described embodiment.
In addition, the first opening 61e of the first collecting part 61a and the second opening 62e of the second collecting part 62a face the direction in which the lubricating oil is scraped up, but the first collecting part 61a and the second collecting part 61a The direction of the collecting portion 62a is not limited to the above-described embodiment.
(C)
The member to which the lubricating oil is supplied by the oil garter 6 may be a synchro mechanism. In this case, the lubrication efficiency of the synchro mechanism is increased and the lubrication performance can be stabilized.

(D)
Although the member that scoops up the lubricating oil is described as the third speed counter gear G13 and the second synchro mechanism S2, the member that scoops up the lubricating oil may be only the gear or only the synchro mechanism.
(E)
The first discharge part 61c has an inclined part 61d. If the first discharge part 61c protrudes from the first intermediate part 61b and is close to the second speed counter gear G12, the inclined part 61d is provided. It does not have to be.
An extension part 64 is provided at the end of the second discharge part 62c. However, if the second discharge part 62c protrudes from the second intermediate part 62b and is close to the counter drive gear G17, the extension part 64 is provided. It does not have to be.

Although the inclined part 61d is provided in the 1st discharge part 61c, the 2nd discharge part 62c may have the same shape as the 1st discharge part 61c. On the contrary, although the extension part 64 is provided in the 2nd discharge part 62c, the part of the same shape as the extension part 64 may be provided also in the 1st discharge part 61c. That is, the first discharge portion 61c may be provided with the inclined portion 61d and the extension portion 64, or the first discharge portion 61c may be provided with only the extension portion 64 instead of the inclined portion 61d.
(F)
The opening area of the first collection part 61a may not be the same as the opening area of the second collection part 62a. For example, the opening area on the side where more lubricating oil is required or the opening area on the side where lubricating oil is difficult to flow may be increased.

Further, the shapes of the first opening 61e and the second opening 62e are not limited to the above-described embodiment.
For example, in the oil garter 206 shown in FIGS. 18 and 19, the area of the second opening 262e of the second collection portion 262a (corresponding to the second collection portion 62a described above) is the first collection portion 261a (the first collection portion 261a described above). It may be larger than the area of the first opening 261e of the collecting portion 61a. In this case, the cross-sectional area of the second flow path P22 (corresponding to the second flow path P2 described above) is larger than the cross-sectional area of the first flow path P21 (corresponding to the first flow path P1 described above). Become. With these configurations, the amount of lubricating oil supplied to the counter drive gear G17 is greater than the amount of lubricating oil supplied to the second speed counter gear G12.
(G)
The arrangement of the oil garter 6 is not limited to the above-described embodiment. For example, the 1st guidance part 61 and the 2nd guidance part 62 may be arranged above the axis of rotation A2 in the perpendicular direction. In this case, since the positions of the first discharge part 61c and the second discharge part 62c are higher than those in the above-described embodiment, the part where the lubricating oil is supplied to the meshing part (the part to be lubricated) (the lubricating oil supply part) Is close. Thereby, the lubrication efficiency of a gear can be improved.

(H)
There may be three or more parts for collecting or guiding the lubricating oil, such as the first guiding part 61 and the second guiding part 62. For example, the inside of the first guiding part 61 (the side opposite to the second guiding part 62 of the first guiding part 61) and the outside of the second guiding part 62 (the side opposite to the first guiding part 61 of the second guiding part 62), Or another guidance part may be arranged in the position of the up-and-down direction different from the 1st guidance part 61 and the 2nd guidance part 62,
Further, the third guide part 63 may be arranged over the entire range of the first guide part 61 and the second guide part 62. In this case, the lubricating oil collecting performance of the third guide portion 63 is enhanced.
(I)
The bottom surfaces of the first guiding part 61 and the second guiding part 62 may be inclined. For example, in the oil garter 306 shown in FIG. 20, the first bottom surface 361f of the first guide portion 361 (corresponding to the first guide portion 61 described above) descends from the third speed counter gear G13 to the counter drive gear G17 with respect to the horizontal plane. It may be inclined like this. Further, the second bottom surface 362f of the second guide portion 362 (corresponding to the second guide portion 62 described above) is inclined so as to descend from the third speed counter gear G13 to the second speed counter gear G12 with respect to the horizontal plane. Also good. In the oil garter 306 shown in FIG. 20, the first bottom surface 361f and the second bottom surface 362f have the same inclination angle.

In this case, the lubricating oil collected by the first collection unit 361a (corresponding to the first collection unit 61a described above) easily flows into the counter drive gear G17 through the first bottom surface 361f by the action of gravity. Further, due to the action of gravity, the lubricating oil collected by the second collecting portion 362a (corresponding to the second collecting portion 62a described above) can easily flow into the second speed counter gear G12 through the second bottom surface 362f. .
(J)
The device to which the lubricating device L is applied is not limited to the transmission 1. The present invention is applicable to any device having a member to be lubricated such as a gear.

  Since the lubrication apparatus according to the present invention can stabilize the lubrication performance, the present invention is useful in the field of apparatuses having a member to be lubricated.
