Description

  The present invention is a belt type continuously variable gear that lubricates and cools belts that engage with the groove portions of both pulleys by injecting lubricating oil toward the groove portions of the drive pulley and the driven pulley of the belt type continuously variable transmission. The present invention relates to a lubricating device for a transmission.

  Conventionally, a belt that lubricates and cools belts that engage with the groove portions of both pulleys by injecting lubricating oil toward the groove portions having a V-shaped cross section of the drive pulley and driven pulley of the belt-type continuously variable transmission. As a lubrication device for a continuously variable transmission, there are lubrication devices described in Patent Documents 1 to 4.

  The belt-type continuously variable transmission described in Patent Document 1 includes oil supply means for injecting oil of an oil pump from a nozzle fixed on the stationary side to the belt substantially parallel to the V groove surface of the fixed flange. .

  In the lubricating device described in Patent Document 2, the injection direction of the injection nozzle that injects a certain amount of lubricating oil onto the V belt is set to the direction toward the sheave surface around which the V belt of the fixed pulley is wound.

  By the way, when lubricating the belt of a continuously variable transmission, the lubricating oil must be supplied from the inside of the belt and supplied so as to be injected almost in parallel with the surface of the V-shaped groove section of the fixed pulley. I must. Therefore, it is necessary to pass the lubricating oil supply pipe (supply pipe) through the gap between the belt and the pulley. In addition, since it is necessary to lubricate both the driving pulley and the driven pulley, it is necessary to provide two injection ports in one supply pipe. In this case, the injection angle (outflow angle) of the lubricating oil from each injection port depends on the flow velocity of the lubricating oil flowing through the supply pipe. Therefore, the injection speed of the lubricating oil differs between the injection port located on the upstream side of the flow and the injection port located on the downstream side. As a result, there is a problem that the installation space for the lubrication structure is increased or the number of parts is increased and the structure is complicated because a nozzle having a different angle setting is required for each injection port.

  The present invention has been made in order to solve the above-described problems. The object of the present invention is to provide a desired configuration from each of a plurality of injection ports provided in the supply pipe while having a small and space-saving configuration with a reduced number of parts. An object of the present invention is to provide a lubricating device for a belt type continuously variable transmission capable of injecting and supplying an appropriate amount of lubricating oil to a position.

  In order to solve the above-described problems, a lubricating device for a belt-type continuously variable transmission according to the present invention includes an endless belt (7) wound around a drive pulley (5) and a driven pulley (6). A lubrication device for a transmission (2), a supply pipe disposed between the drive pulley (5) and the driven pulley (6) along the axial direction of the drive pulley (5) and the driven pulley (6) (25) and a groove (12) provided in the supply pipe (25) for engaging the belt (7) of the drive pulley (5) and the groove (21) for engaging the belt (7) of the driven pulley (6). ) And a drive pulley (5) provided at a position downstream of the first injection port (27) in the supply pipe (25) and the first injection port (27) for injecting the lubricant toward one of Toward the other of the groove (12) and the groove (21) of the driven pulley (6) A second injection port (28) for injecting the lubricating oil, and one end (25a) of the supply pipe (25) is an inflow end connected to the supply source (26) of the lubricating oil, The other end portion (25b) of 25) is a closed closing portion (29), and the first injection port (27) has a fixed pulley half (10) and a driven pulley ( 6) The fixed pulley half (19) of the fixed pulley half (19) is opened toward the end (21b) on the large diameter side of the surface (21a) of the fixed pulley half (19) located upstream of the supply pipe (25). On the other hand, the second injection port (28) opens toward the other groove (12) of the drive pulley (5) and the driven pulley (6), and the peripheral wall of the supply pipe (25) ( The inner diameter of the supply pipe (25) on the downstream side of the first injection port (27) and the upstream side of the second injection port (28) in 25c) Characterized by providing projecting portions (31) projecting.

  According to the lubricating device for the belt type continuously variable transmission according to the present invention, the lubricating oil injected from the first injection port on the upstream side is affected by the flow velocity of the lubricating oil flowing in the supply pipe. Therefore, the direction in which the lubricating oil is injected is the direction from the first injection port toward the downstream side. As a result, the nozzle having a special angle or shape is formed by opening the first injection port toward the large-diameter end of the surface of the fixed pulley half located upstream of the supply pipe as described above. The lubricating oil injected from the first injection port can be injected substantially in parallel along the surface of the fixed pulley (the sheave surface around which the belt is wound). Therefore, since the lubricating oil is injected along the moving direction of the belt, it is possible to always supply the lubricating oil to the belt.

  In addition, by providing a protruding portion that protrudes toward the inner diameter side of the supply pipe on the downstream side of the first injection port and on the upstream side of the second injection port in the peripheral wall of the supply pipe, the protrusion causes the second injection port to Since the stagnation of the flowing lubricating oil is formed, the flow velocity of the lubricating oil injected from the second injection port can be increased. Thereby, the spread of the lubricating oil injected from the second injection port can be suppressed, and the lubricating oil can be easily supplied to a desired position. Therefore, the belt can be efficiently lubricated by the lubricating oil injected from the second injection port that opens toward the other groove of the drive pulley and the driven pulley.

  Further, in the above lubricating device, the second injection port (28) inclines a part in the circumferential direction of the peripheral wall (25c) of the supply pipe (25) gradually from the upstream side toward the downstream side toward the outer diameter side. It may be an opening provided in the inclined portion (32).

  According to this configuration, the lubricating oil injected from the second injection port is opened on the upstream side of the supply pipe by opening the second injection port in an inclined state so as to face the upstream side of the supply pipe. It becomes the direction inclined diagonally toward. Thereby, the lubricating oil injected from the second injection port is injected substantially parallel along the surface of the drive pulley or the driven pulley. Therefore, since the lubricating oil is injected along the moving direction of the belt, it is possible to always supply the lubricating oil to the belt.

  Moreover, in the above-described lubricating device, a hollow portion (30) is formed by recessing a part of the peripheral wall (25c) of the supply pipe (25) in a wedge shape, and the hollow portion (30) protrudes from the inclined portion (32). The projecting portion (31) is preferably an angular portion projecting to the inner diameter side provided at the end on the upstream side of the inclined portion (32).

  According to this configuration, the second injection port is configured with a simple configuration in which a recess is formed by recessing a part of the peripheral wall of the supply pipe in a wedge shape and an opening is provided in the inclined portion of the recess. Can be configured. Therefore, the second injection port can be provided with a simple and space-saving configuration with a small number of parts.

  In the above lubricating device, the first injection port (27) and the second injection port (28) are each provided with cylindrical guide portions (27a, 28a) for guiding the lubricating oil to be injected. Good.

According to this configuration, since the lubricating oil injected from the first injection port and the second injection port can be guided by the cylindrical guide portion, the lubricating oil injected from the first injection port and the second injection port , And the injected lubricating oil can be injected more accurately toward the lubricating position.
In addition, the code | symbol in said parenthesis shows the code | symbol of the component in embodiment mentioned later as an example of this invention.

  According to the lubricating device for a belt-type continuously variable transmission according to the present invention, it is suitable for a desired position from each of a plurality of injection ports provided in the supply pipe while having a small and space-saving configuration with a reduced number of parts. An amount of lubricating oil can be injected and supplied.

FIG. 2 is a sectional view taken along line 2-2 of FIG. FIG. 3 is a three-part enlarged view of FIG. 2. It is a figure which shows the detailed structure of the 1st injection port provided in the supply pipe, and the 2nd injection port. It is a figure which shows the other structural example of a 1st injection port and a 2nd injection port.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a side view of a belt type continuously variable transmission for an automobile including a lubricating device according to an embodiment of the present invention. 2 is a cross-sectional view taken along line 2-2 of FIG. FIG. 3 is an enlarged view of part 3 of FIG.

  1 and 2, a belt type continuously variable transmission 2 is accommodated in a transmission case 1 of a power unit mounted on an automobile. The belt-type continuously variable transmission 2 includes an input shaft 3 and an output shaft 4 that are rotatably supported in parallel to the transmission case 1, a drive pulley 5 that is attached to the input shaft 3, and a driven that is attached to the output shaft 4. A pulley 6 and an endless metal V-belt (belt) 7 wound around the input shaft 3 and the output shaft 4 are provided.

  The driving pulley 5 is integrally fixed to a fixed pulley half 10 having a cylindrical shaft 10a rotatably supported by the input shaft 3, and is supported by the cylindrical shaft 10a so as to be slidable in the axial direction and not relatively rotatable. The movable pulley half 11 forms a belt groove (groove portion) 12 having a V-shaped cross section in cooperation with the pulley half 10. A forward / reverse switching device 13 is provided between the input shaft 3 and the cylinder shaft 10a. The forward / reverse switching device 13 includes a planetary gear mechanism 14, a forward clutch 15, and a reverse brake 16. When the forward clutch 15 is connected, the input shaft 3 and the cylindrical shaft 10a are directly connected, that is, between the input shaft 3 and the fixed pulley half 10, and when the reverse brake 16 is operated, the rotation of the input shaft 3 is decelerated, and The reverse rotation is transmitted to the fixed pulley half 10.

  Further, a first hydraulic piston 17 that can shift the movable pulley half 11 steplessly along the axial direction is provided between the cylindrical shaft 10 a and the movable pulley half 11.

  The driven pulley 6 is supported by the fixed pulley half 19 integrally formed with the output shaft 4, and is supported on the output shaft 4 so as to be axially slidable and relatively non-rotatable, and in cooperation with the fixed pulley half 19. The movable pulley half 20 forms a belt groove (groove portion) 21 having a V-shaped cross section.

  In the above, the fixed pulley halves 10 and 19 and the movable pulley halves 11 and 20 are arranged on a diagonal line, respectively.

  The V belt 7 is wound around the drive pulley 5 and the driven pulley 6 so as to engage with the belt grooves 12 and 21, and the movable pulley half 20 is fixed to the fixed pulley half so as to apply a constant tension to the V belt 7. A return spring 22 that urges the body 19 is contracted between the movable pulley half 20 and the output shaft 4. Further, a second hydraulic piston 23 for controlling the movement of the movable pulley half 20 in the axial direction is provided between the movable pulley half 20 and the output shaft 4.

  Thus, by controlling the first and second hydraulic pistons 17, 23, the movable pulley half 11 is separated from the fixed pulley half 10 in the drive pulley 5, and at the same time, the movable pulley half in the driven pulley 6. When the belt 20 approaches the stationary pulley half 19, the V-belt 7 moves to the smaller diameter side of the belt groove 12 of the driving pulley 5 and moves to the larger diameter side of the belt groove 21 of the driven pulley 6 (see FIG. 2), the gear ratio between the drive pulley 5 and the driven pulley 6 can be changed to the LOW side. Further, when the movable pulley half 11 is brought close to the fixed pulley half 10 in the drive pulley 5 and at the same time the movable pulley half 20 is separated from the fixed pulley half 19 in the driven pulley 6, the V belt 7 is driven. The pulley 5 moves to the large-diameter side of the belt groove 12 and moves to the small-diameter side of the belt groove 21 of the driven pulley 6 (see the upper half of each pulley 5 and 6 in FIG. 2), thereby driving pulley 5 The gear ratio between the driven pulley 6 and the driven pulley 6 can be changed to the OD side.

  2 and 3, a supply pipe (lubricating oil supply pipe) 25 supported by the left and right side walls 1a and 1b of the transmission case 1 is provided between the drive pulley 5 and the driven pulley 6. 6 are disposed along the axial direction. As shown in FIG. 3, one end (upstream end) 25a of the supply pipe 25 passes through the right side wall 1b and is connected to an oil supply source 26 such as an oil pump, and the other end. The part (downstream end part) 25b is a closed part 29 closed (closed) by the left side wall 1a that supports it.

  The supply pipe 25 has a thickness t of the peripheral wall 25c as thin as 0.5 mm, for example. The first injection port 27 is provided in the peripheral wall 25c, and the downstream side of the supply pipe 25 from the first injection port 27 (oil supply source). The second injection ports 28 which are offset to the opposite side of the nozzle 26 are respectively drilled.

  The first injection port 27 is a conical belt engaging surface of one of the driving pulley 5 and the driven pulley 6, a fixed pulley half located upstream of the supply pipe 25, in the illustrated example, the driven fixed pulley half 19. (Surface) 21a is arranged so as to open toward the large-diameter portion (end portion on the large-diameter side) 21b. The second injection port 28 is disposed so as to open toward the belt groove 12 of the drive pulley 5 in the illustrated example, on the other side of the drive pulley 5 and the driven pulley 6.

  FIG. 4 is a diagram illustrating a detailed configuration of the first injection port 27 and the second injection port 28 provided in the supply pipe 25. As shown in the figure, the second injection port 28 has a configuration in which a recess 30 is formed by recessing a part of the peripheral wall 25c of the supply pipe 25 in a wedge shape, and an opening 30a is provided in a part of the recess 30. It is. The recess 30 includes an inclined surface 32 in which a part of the circumferential direction of the peripheral wall 25c of the supply pipe 25 is gradually inclined from the upstream side toward the downstream side toward the outer diameter side (in the direction of expanding the diameter), and the inclined surface 32 and an angular protrusion 31 that protrudes toward the inner diameter provided at the upstream end. The inclined surface 32 has a substantially flat surface. The opening 30a is formed in the middle of the inclined surface 32 (in the middle of the direction from the upstream side to the downstream side of the supply pipe 25). Thereby, the protrusion part 31 is located in the upstream of the opening 30a, and the inclined surface 32 (a part) is located in the downstream of the opening 30a.

  That is, a protruding portion 31 that protrudes toward the inner diameter side of the supply pipe 25 is provided at a position upstream of the second injection port 28 and downstream of the first injection port 27 in the peripheral wall 25 c of the supply pipe 25. Yes. Further, on the downstream side of the second injection port 28 in the peripheral wall 25c of the supply pipe 25, an inclined surface 32 that is inclined so as to gradually go from the upstream side toward the downstream side toward the outer peripheral side is provided. Further, since the opening 30 a is provided in the middle of the inclined surface 32, the opening 30 a of the second injection port 28 is opened in an inclined state so as to face the upstream side of the supply pipe 25.

  Next, lubrication of the belt 7 by the lubrication device provided with the supply pipe 25 having the above-described configuration will be described. During operation of the belt type continuously variable transmission 2, when oil (lubricating oil) is pumped from the oil supply source 26 to the supply pipe 25, the lubricating oil L 1 is fed from the first injection port 27 of the supply pipe 25 to the belt of the driven pulley 6. Injected toward the groove 21, and the lubricating oil L <b> 2 is injected from the second injection port 28 toward the belt groove 12 of the drive pulley 5. At that time, since the first injection port 27 is disposed upstream of the second injection port 28 in the supply pipe 25, that is, at a position closer to the oil supply source 26, the injection direction of the lubricating oil from the first injection port 27. Is strongly influenced by the flow of the lubricating oil in the supply pipe 25, and is inclined from the center line of the first injection port 27 to the downstream side of the supply pipe 25.

  Since the first injection port 27 is disposed so as to open toward the end 21b on the large diameter side of the conical belt engaging surface 21a in the stationary pulley half 19 of the driven pulley 6, the first injection port 27 is provided. The direction in which the lubricating oil L1 injected from the injection direction is substantially parallel to the conical belt engaging surface 21a. As a result, the lubricating oil L1 can be injected from the first injection port 27 along the conical belt engaging surface 21a from the large diameter portion to the small diameter portion. Therefore, as shown in FIG. 4, it is possible to supply lubricating oil to the V-belt 7 at any position (shifting position) of the V-belt 7 on the driven pulley 6 side. It can always be done efficiently.

  That is, in the supply pipe 25 of the present embodiment, the lubricating oil L1 injected from the upstream first injection port 27 is affected by the flow velocity of the lubricating oil flowing through the supply pipe 25, so the injection direction is the first. It goes toward the downstream side from one injection port 27. Therefore, as described above, by opening the first injection port 27 toward the end 21b on the large diameter side of the belt engagement surface 21a of the fixed pulley half 19 located on the upstream side of the supply pipe, Without separately installing a nozzle having a special angle or shape, the lubricating oil L1 injected from the first injection port 27 is applied to the belt engaging surface of the fixed pulley half 19 (the sheave surface to which the V belt 7 is engaged). ) It can be sprayed substantially parallel along 21a. Thereby, since the lubricating oil L1 is injected along the moving direction of the V-belt 7, the lubricating oil can always be supplied to the V-belt 7.

  Further, in the present embodiment, the downstream end portion 25 b of the supply pipe 25 is closed by the closing portion 29, and the protruding portion is provided upstream of the first injection port 27 and downstream of the second injection port 28. By providing 31, the stagnation part M comes to be formed by the flow of the lubricating oil flowing toward the second injection port 28 in the supply pipe 25 as shown in FIG. Thereby, the lubricating oil L2 injected from the second injection port 28 is hardly affected by the flow velocity. Therefore, the spread of the lubricating oil L2 injected from the second injection port 28 can be suppressed, and the lubricating oil L2 can be easily supplied to a desired position. Thereby, as the lubrication by the lubricating oil L2 ejected from the second injection port 28, it becomes possible to efficiently lubricate the V-belt 7 with a more appropriate supply amount of the lubricating oil.

  Moreover, in this embodiment, the 2nd injection port 28 is in the middle of the inclined surface 32 formed by inclining a part of the circumferential direction in the surrounding wall 25c of the supply pipe 25 gradually toward the outer diameter side from the upstream side toward the downstream side. It is the opening provided in. With this configuration, since the second injection port 28 is opened in an inclined state so as to face the upstream side of the supply pipe 25, the lubricating oil L <b> 2 injected from the second injection port 28 is supplied in the injection direction. The direction is inclined obliquely toward the upstream side of the tube 25. As a result, the lubricating oil L2 injected from the second injection port 28 is injected substantially in parallel along the surface of the fixed pulley half 10 of the drive pulley 5. Therefore, since the lubricating oil L2 is injected along the moving direction of the belt 7, the lubricating oil can be always supplied to the belt 7.

  FIG. 5 is a diagram illustrating another configuration example (modified example) of the first injection port 27 and the second injection port 28. In the configuration example shown in FIG. 5A, cylindrical guide portions 27a and 28a for guiding the lubricant to be injected are provided in the first injection port 27 and the second injection port 28, respectively. According to this configuration example, as compared with the configuration example shown in FIG. 4 described above, the lubricating oil injected by the guide portions 27a and 28a is guided to inject from the first injection port 27 and the second injection port 28. The spread of the lubricating oil to be applied can be more effectively suppressed, and the injected lubricating oil can be injected more accurately toward the lubricating position.

  In addition, although illustration is omitted, in the configuration example shown in FIG. 5A, only one of the guide part 27a provided at the first injection port 27 and the guide part 28a provided at the second injection port 28 is provided. It is also possible to provide it.

  The configuration example illustrated in FIG. 5B is obtained by further modifying the shape of the peripheral wall 25c of the supply pipe 25 corresponding to the first injection port 27 with respect to the configuration example illustrated in FIG. That is, here, the peripheral wall 25c of the portion where the first injection port 27 is provided is deformed so as to become a flat inclined surface 34 that gradually inclines from the outer diameter side to the inner diameter side from the upstream side toward the downstream side. As a result, the first injection port 27 is opened in an inclined state so as to face the downstream side of the supply pipe 25, so that the injection direction of the lubricating oil injected from the first injection port 27 is downstream of the supply pipe 25. The direction is inclined obliquely toward the side. Therefore, the lubricating oil L1 injected from the first injection port 27 can be more reliably injected substantially in parallel along the conical belt engaging surface 21a of the fixed pulley half 19. Therefore, it is possible to further improve the aiming accuracy of the lubricating oil L1 ejected from the first ejection port 27, and to efficiently lubricate the V-belt 7 with a more appropriate supply amount.

  In addition, although illustration is omitted, in the configuration example shown in FIG. 5B, both or one of the guide portion 27 a provided in the first injection port 27 and the guide portion 28 a provided in the second injection port 28 is used. It can be omitted.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims and the technical idea described in the specification and drawings. Can be modified. For example, in FIGS. 2 and 3, when the left end side of the supply pipe 25 is connected to the oil supply source 26, the first injection port 27 is arranged on the left side, the second injection port 28 is arranged on the right side, and the first injection The opening 27 is opened toward the large diameter portion of the belt engaging surface of the fixed pulley half 10 on the driving side, and the second injection port 28 is opened toward the belt groove 21 of the driven pulley 6.
