Description

本発明は、車両に適用される変速機の潤滑装置に関し、特に、変速機のケーシング内が縦壁によって第1室と第2室に区画されていて、前記第1室に変速ギヤと潤滑油(前記第1室内の変速ギヤにより掻き上げられて同変速ギヤの噛合部を少なくとも潤滑するもの)が収容されるとともに、前記第2室に変速ギヤと潤滑油(前記第2室内の変速ギヤにより掻き上げられて同変速ギヤの噛合部を少なくとも潤滑するもの)が収容されている変速機の潤滑装置に関する。   The present invention relates to a transmission lubrication device applied to a vehicle, and in particular, a casing of a transmission is partitioned into a first chamber and a second chamber by a vertical wall, and a transmission gear and lubricating oil are provided in the first chamber. (The one that is scraped up by the transmission gear in the first chamber and at least lubricates the meshing portion of the transmission gear) is accommodated, and the transmission gear and lubricating oil (by the transmission gear in the second chamber) are stored in the second chamber.

特開平11−294565号公報JP 11-294565 A

上記特許文献1に記載されている変速機においては、例えば、車両の急加速走行時や急坂登坂路走行時に、縦壁の底部に形成した連通孔を通して、第1室(前方室)内の潤滑油が第2室(後方室)内に流れて移動し、第1室(前方室)内の潤滑油が不十分となることがある。また、例えば、車両の急減速走行時や急坂下り坂路走行時に、縦壁の底部に形成した連通孔を通して、第2室(後方室)内の潤滑油が第1室(前方室)内に流れて移動し、第2室(後方室)内の潤滑油が不十分となることがある。   In the transmission described in Patent Document 1, for example, when the vehicle is traveling at a rapid acceleration or traveling on a steep slope, the lubrication in the first chamber (front chamber) is made through a communication hole formed at the bottom of the vertical wall. Oil may flow into the second chamber (rear chamber) and move, and the lubricating oil in the first chamber (front chamber) may become insufficient. Further, for example, when the vehicle is running at a sudden deceleration or running down a steep slope, the lubricating oil in the second chamber (rear chamber) flows into the first chamber (front chamber) through the communication hole formed at the bottom of the vertical wall. And the lubricating oil in the second chamber (rear chamber) may become insufficient.

本発明の目的は、上記した如何なる走行時においても、第1室と第2室に所定量の潤滑油が貯えられるように構成して、第1室と第2室での潤滑油不足を解消することにある。かかる目的を達成するために、本発明では、変速機のケーシング内が縦壁によって第1室と第2室に区画されていて、前記第1室に変速ギヤと潤滑油が収容されるとともに、前記第2室に変速ギヤと潤滑油が収容されており、前記縦壁の底部に形成した連通孔を通して前記第1室内の潤滑油と前記第2室内の潤滑油が流通可能に構成されている変速機の潤滑装置において、前記連通孔に、前記第1室から前記第2室に潤滑油が慣性力で流動するときに同潤滑油の流動を制御するとともに、前記第2室から前記第1室に潤滑油が慣性力で流動するときに同潤滑油の流動を制御する制御弁を設けた。   It is an object of the present invention to eliminate a shortage of lubricating oil in the first chamber and the second chamber by configuring a predetermined amount of lubricating oil to be stored in the first chamber and the second chamber during any travel described above. There is to do. In order to achieve this object, in the present invention, the inside of the casing of the transmission is partitioned into a first chamber and a second chamber by a vertical wall, and the transmission gear and lubricating oil are accommodated in the first chamber, The transmission gear and the lubricating oil are accommodated in the second chamber, and the lubricating oil in the first chamber and the lubricating oil in the second chamber can be circulated through a communication hole formed in the bottom of the vertical wall. In the transmission lubrication device, the flow of the lubricating oil is controlled by the inertia force when the lubricating oil flows from the first chamber to the second chamber through the communication hole, and from the second chamber to the first chamber. A control valve is provided in the chamber for controlling the flow of the lubricating oil when the lubricating oil flows by inertia.

このため、本発明による変速機の潤滑装置では、当該変速機において、第1室が例えば前方室とされ第2室が例えば後方室とされるように車両に配備される場合、例えば、車両の急加速走行時や急坂登坂路走行時に、縦壁の底部に形成した連通孔を通して、第1室(前方室)内の潤滑油が第2室(後方室)内に向けて慣性力で流動するときに、同潤滑油の流動が制御弁により制御されて、第1室と第2室にそれぞれ所定量の潤滑油が貯えられる。また、例えば、車両の急減速走行時や急坂下り坂路走行時に、縦壁の底部に形成した連通孔を通して、第2室(後方室)内の潤滑油が第1室(前方室)内に向けて慣性力で流動するときに、同潤滑油の流動が制御弁により制御されて、第1室と第2室にそれぞれ所定量の潤滑油が貯えられる。したがって、上記した如何なる走行時においても、第1室と第2室にそれぞれ所定量の潤滑油が貯えられる。このため、第1室と第2室での潤滑油不足を解消することが可能である。   For this reason, in the transmission lubrication device according to the present invention, in the transmission, when the first chamber is disposed in the vehicle such as the front chamber and the second chamber is defined as the rear chamber, for example, Lubricating oil in the first chamber (front chamber) flows with inertial force into the second chamber (rear chamber) through the communication hole formed in the bottom of the vertical wall during rapid acceleration traveling or steep climbing. Sometimes, the flow of the lubricating oil is controlled by the control valve, and a predetermined amount of lubricating oil is stored in the first chamber and the second chamber, respectively. In addition, for example, when the vehicle is traveling at a sudden deceleration or traveling down a steep slope, the lubricating oil in the second chamber (rear chamber) is directed toward the first chamber (front chamber) through the communication hole formed in the bottom of the vertical wall. When the fluid flows with inertial force, the flow of the lubricating oil is controlled by the control valve, and a predetermined amount of lubricating oil is stored in the first chamber and the second chamber, respectively. Therefore, a predetermined amount of lubricating oil is stored in each of the first chamber and the second chamber during any of the above-described travels. For this reason, it is possible to eliminate the lack of lubricating oil in the first chamber and the second chamber.

上記した本発明の実施に際して、前記制御弁は、前記潤滑油の密度より高密度の素材からなり慣性力で前記連通孔内を移動可能な慣性弁体と、前記連通孔から前記第1室に向けて延在する第1弁孔とこの第1弁孔に設けられて前記慣性弁体が着座・離座可能な第1弁座を有していて前記慣性弁体と協働して前記第2室から前記第1室への潤滑油の流動を制御する第1弁座部材と、前記連通孔から前記第2室に向けて延在する第2弁孔とこの第2弁孔に設けられて前記慣性弁体が着座・離座可能な第2弁座を有していて前記慣性弁体と協働して前記第1室から前記第2室への潤滑油の流動を制御する第2弁座部材を備えていて、前記第1室側に向けて作用する慣性力が第1設定値以上のときに前記慣性弁体が前記第1弁座に着座し第1設定値未満のときに前記慣性弁体が前記第1弁座から離座するように設定され、前記第2室側に向けて作用する慣性力が第2設定値以上のときに前記慣性弁体が前記第2弁座に着座し第2設定値未満のときに前記慣性弁体が前記第2弁座から離座するように設定されていることも可能である。この場合には、ケーシングの連通孔に設けられる制御弁をシンプルに構成することができて、安価に製作することが可能である。   In carrying out the above-described present invention, the control valve is made of a material having a higher density than the density of the lubricating oil and is movable in the communication hole by an inertial force. The control valve is moved from the communication hole to the first chamber. A first valve hole extending toward the first valve hole, and a first valve seat provided in the first valve hole on which the inertia valve body can be seated / separated, and in cooperation with the inertia valve body. A first valve seat member for controlling the flow of lubricating oil from the two chambers to the first chamber; a second valve hole extending from the communication hole toward the second chamber; and the second valve hole. The inertia valve body has a second valve seat that can be seated and separated, and controls the flow of lubricating oil from the first chamber to the second chamber in cooperation with the inertia valve body. A valve seat member is provided, and when the inertial force acting toward the first chamber is equal to or greater than a first set value, the inertia valve body is seated on the first valve seat and the first set value is not The inertia valve body is set so as to be separated from the first valve seat, and the inertia valve body is moved to the second chamber when the inertial force acting toward the second chamber side is equal to or greater than a second set value. It is also possible to set the inertia valve body so as to be separated from the second valve seat when it is seated on the two valve seats and less than the second set value. In this case, the control valve provided in the communication hole of the casing can be simply configured and can be manufactured at low cost.

また、この場合において、前記各弁座には、前記慣性弁体が着座した状態でも所定量の潤滑油流通を許容する通路が設けられていることも可能である。この場合には、慣性弁体が各弁座に長時間着座し続けても、ケーシング内の潤滑油を第1室から第2室または第2室から第1室に流動させることができて、潤滑油を両室間で流動させない場合に比して、各室内の潤滑油の温度上昇を効果的に抑えることが可能である。   Further, in this case, each valve seat may be provided with a passage that allows a predetermined amount of lubricating oil to flow even when the inertia valve body is seated. In this case, the lubricating oil in the casing can flow from the first chamber to the second chamber or from the second chamber to the first chamber even if the inertia valve body continues to sit on each valve seat for a long time, As compared with the case where the lubricating oil does not flow between the two chambers, the temperature rise of the lubricating oil in each chamber can be effectively suppressed.

FIG. 1 schematically shows an embodiment of a transmission lubrication device according to the present invention. In the transmission 100 shown in FIG. 1, an input shaft 10 and an output shaft 20 that extend along the longitudinal direction of the vehicle. Are arranged so as to be coaxial and relatively rotatable, and a countershaft 30 is arranged in parallel to these shafts 10 and 20. A casing 90 that rotatably supports the shafts 10, 20, and 30 includes a vertical wall 91. The vertical wall 91 allows the casing 90 to have a front chamber Ra (first chamber) and a rear chamber Rb (first chamber). 2 rooms).

また、図1に示した変速機100では、インプットギヤ対Gi、第1速ギヤ対G1、第2速ギヤ対G2、第3速ギヤ対G3と、1−2変速機構C1、3−4変速機構C2が前方室Raに収容されるとともに、所要量の潤滑油Oaが前方室Raに収容されている。一方、第5速ギヤ対G5、リバースギヤ列Grと、5−R変速機構C3が後方室Rbに収容されるとともに、所要量の潤滑油Obが後方室Rbに収容されている。また、前方室Ra内の潤滑油Oaと後方室Rb内の潤滑油Obが、縦壁91の底部に形成した連通孔91aを通して、流通可能に構成されている。   In the transmission 100 shown in FIG. 1, the input gear pair Gi, the first speed gear pair G1, the second speed gear pair G2, the third speed gear pair G3, the 1-2 speed change mechanism C1, and the 3-4 speed change. The mechanism C2 is accommodated in the front chamber Ra, and a required amount of lubricating oil Oa is accommodated in the front chamber Ra. On the other hand, the fifth gear pair G5, the reverse gear train Gr, and the 5-R transmission mechanism C3 are accommodated in the rear chamber Rb, and a required amount of lubricating oil Ob is accommodated in the rear chamber Rb. Further, the lubricating oil Oa in the front chamber Ra and the lubricating oil Ob in the rear chamber Rb are configured to be able to flow through the communication hole 91 a formed in the bottom of the vertical wall 91.

ところで、この実施形態においては、連通孔91aに制御弁80が設けられている。制御弁80は、前方室Raから後方室Rbに潤滑油が慣性力で流動するときに同潤滑油の流動を制御するとともに、後方室Rbから前方室Raに潤滑油が慣性力で流動するときに同潤滑油の流動を制御するものであり、図2にて拡大して示したように、慣性弁体81と、この慣性弁体81より前方室Ra側に設けた第1弁座部材82と、慣性弁体81より後方室Rb側に設けた第2弁座部材83を備えている。   By the way, in this embodiment, the control valve 80 is provided in the communication hole 91a. The control valve 80 controls the flow of the lubricating oil when the lubricating oil flows from the front chamber Ra to the rear chamber Rb by the inertial force, and also when the lubricating oil flows from the rear chamber Rb to the front chamber Ra by the inertial force. As shown in an enlarged view in FIG. 2, an inertia valve body 81 and a first valve seat member 82 provided on the front chamber Ra side from the inertia valve body 81 are controlled. And a second valve seat member 83 provided on the rear chamber Rb side from the inertia valve body 81.

慣性弁体81は、上記した潤滑油Oa、Obの密度より高密度の素材からなり、車両前後方向の慣性力で連通孔91a内と後述する第1弁孔82aおよび第2弁孔83aの大径部分(慣性弁体81の径より大径の部分)を前後方向に移動可能(転動可能)なボール弁体である。   The inertia valve body 81 is made of a material having a density higher than the density of the lubricating oils Oa and Ob described above, and is large in the communication hole 91a and the first valve hole 82a and the second valve hole 83a described later by inertia force in the vehicle longitudinal direction. This is a ball valve body that can move (roll) a diameter portion (a portion larger than the diameter of the inertia valve body 81) in the front-rear direction.

第1弁座部材82は、連通孔91aから前方室Raに向けて延在する円錐台形状の第1弁孔82aと、この第1弁孔82aに設けられて慣性弁体81が着座・離座可能な円形の第1弁座82bを有していて、慣性弁体81と協働して後方室Rbから前方室Raへの潤滑油の流動を制御する。   The first valve seat member 82 is provided with a frustoconical first valve hole 82a extending from the communication hole 91a toward the front chamber Ra, and the inertia valve body 81 is seated and separated by the first valve hole 82a. It has a seatable circular first valve seat 82b and controls the flow of lubricating oil from the rear chamber Rb to the front chamber Ra in cooperation with the inertia valve body 81.

第2弁座部材83は、連通孔91aから後方室Rbに向けて延在する円錐台形状の第2弁孔83aと、この第2弁孔83aに設けられて慣性弁体81が着座・離座可能な円形の第2弁座83bを有していて、慣性弁体81と協働して前方室Raから後方室Rbへの潤滑油の流動を制御する。   The second valve seat member 83 is provided with a truncated cone-shaped second valve hole 83a extending from the communication hole 91a toward the rear chamber Rb, and the inertia valve body 81 is seated and separated by the second valve hole 83a. It has a seatable circular second valve seat 83b, and controls the flow of lubricating oil from the front chamber Ra to the rear chamber Rb in cooperation with the inertia valve body 81.

また、この実施形態の制御弁80では、前方室Ra側に向けて作用する車両前方への慣性力が第1設定値以上のときに慣性弁体81が第1弁座82bに着座し、第1設定値未満のときに慣性弁体81が第1弁座82bから離座するように設定されている。また、後方室Rb側に向けて作用する車両後方への慣性力が第2設定値以上のときに慣性弁体81が第2弁座83bに着座し、第2設定値未満のときに慣性弁体81が第2弁座83bから離座するように設定されている。   Further, in the control valve 80 of this embodiment, the inertia valve body 81 is seated on the first valve seat 82b when the inertial force forward of the vehicle acting toward the front chamber Ra is greater than or equal to the first set value. The inertia valve body 81 is set so as to separate from the first valve seat 82b when it is less than one set value. The inertia valve body 81 is seated on the second valve seat 83b when the vehicle rear inertia force acting toward the rear chamber Rb is equal to or greater than the second set value, and the inertia valve is less than the second set value. The body 81 is set so as to be separated from the second valve seat 83b.

なお、この実施形態では、上述した第1弁孔82aと第1弁座82bおよび第2弁孔83aと第2弁座83bが、連通孔91aに対して同軸的に設けられている。また、上述した第1設定値と第2設定値が、同じとなるように、第2弁座部材83と第2弁座部材83が同一形状に形成されている。上述した第1設定値と第2設定値は、異なるように設定されていてもよい。   In this embodiment, the first valve hole 82a and the first valve seat 82b and the second valve hole 83a and the second valve seat 83b described above are provided coaxially with respect to the communication hole 91a. Further, the second valve seat member 83 and the second valve seat member 83 are formed in the same shape so that the first set value and the second set value described above are the same. The first setting value and the second setting value described above may be set differently.

上記のように構成したこの実施形態では、通常時(例えば、平坦路での定速走行時)、制御弁80が図2に示した状態にあって、慣性弁体81が第1弁座82bと第2弁座83bから離座しており、前方室Ra内の潤滑油Oaと後方室Rb内の潤滑油Obが、縦壁91の底部に形成した連通孔91aを通して、流通可能であり、所要量の潤滑油Oaが前方室Raに収容され、所要量の潤滑油Obが後方室Rbに収容されている。   In this embodiment configured as described above, the control valve 80 is in the state shown in FIG. 2 during normal times (for example, when traveling at a constant speed on a flat road), and the inertia valve body 81 is the first valve seat 82b. The lubricating oil Oa in the front chamber Ra and the lubricating oil Ob in the rear chamber Rb can flow through the communication hole 91a formed in the bottom of the vertical wall 91, A required amount of lubricating oil Oa is accommodated in the front chamber Ra, and a required amount of lubricating oil Ob is accommodated in the rear chamber Rb.

このため、前方室Ra内に貯えられる潤滑油Oaは、前方室Ra内の各変速ギヤ対Gi、G1、G2、G3におけるカウンタギヤにより掻き上げられて、同変速ギヤ対Gi、G1、G2、G3の噛合部を少なくとも潤滑することが可能である。また、後方室Rb内に貯えられる潤滑油Obは、第5速ギヤ対G5のカウンタギヤにより掻き上げられて、第5速ギヤ対G5、リバースギヤ列Grの噛合部を少なくとも潤滑することが可能である。   For this reason, the lubricating oil Oa stored in the front chamber Ra is scraped up by the counter gears in the respective transmission gear pairs Gi, G1, G2, G3 in the front chamber Ra, and the transmission gear pairs Gi, G1, G2, It is possible to lubricate at least the meshing portion of G3. Further, the lubricating oil Ob stored in the rear chamber Rb is scraped up by the counter gear of the fifth speed gear pair G5, and at least the meshing portions of the fifth speed gear pair G5 and the reverse gear train Gr can be lubricated. It is.

また、この実施形態では、例えば、車両の急加速走行時や急坂登坂路走行時(後方室Rb側に向けて作用する慣性力が第2設定値以上のとき)、制御弁80が図3の(a)に示した状態にあって、慣性弁体81が第2弁座83bに着座し第1弁座82bから離座している。このため、縦壁91の底部に形成した連通孔91aを通して、前方室Ra内の潤滑油Oaが後方室Rb内に向けて慣性力で流動するときに、同潤滑油の流動が制御弁80により制御(規制)されて、前方室Raと後方室Rbにそれぞれ所定量の潤滑油が貯えられる。   In this embodiment, for example, when the vehicle is traveling at a rapid acceleration or traveling up a steep slope (when the inertial force acting toward the rear chamber Rb is equal to or greater than the second set value), the control valve 80 is shown in FIG. In the state shown in (a), the inertia valve body 81 is seated on the second valve seat 83b and is separated from the first valve seat 82b. For this reason, when the lubricating oil Oa in the front chamber Ra flows into the rear chamber Rb with an inertia force through the communication hole 91a formed in the bottom of the vertical wall 91, the flow of the lubricating oil is controlled by the control valve 80. Controlled (regulated), a predetermined amount of lubricating oil is stored in each of the front chamber Ra and the rear chamber Rb.

また、例えば、車両の急減速走行時や急坂下り坂路走行時(前方室Ra側に向けて作用する慣性力が第1設定値以上のとき)、制御弁80が図3の(b)に示した状態にあって、慣性弁体81が第1弁座82bに着座し第2弁座83bから離座している。このため、縦壁91の底部に形成した連通孔91aを通して、後方室Rb内の潤滑油Obが前方室Ra内に向けて慣性力で流動するときに、同潤滑油の流動が制御弁80により制御(規制)されて、前方室Raと後方室Rbにそれぞれ所定量の潤滑油が貯えられる。   Further, for example, when the vehicle is running at a sudden deceleration or running down a steep slope (when the inertial force acting toward the front chamber Ra side is equal to or higher than the first set value), the control valve 80 is shown in FIG. In this state, the inertia valve body 81 is seated on the first valve seat 82b and is separated from the second valve seat 83b. For this reason, when the lubricating oil Ob in the rear chamber Rb flows into the front chamber Ra by an inertia force through the communication hole 91a formed in the bottom portion of the vertical wall 91, the flow of the lubricating oil is controlled by the control valve 80. Controlled (regulated), a predetermined amount of lubricating oil is stored in each of the front chamber Ra and the rear chamber Rb.

したがって、上記した如何なる走行時においても、前方室Raと後方室Rbにそれぞれ所定量の潤滑油が貯えられる。このため、前方室Raと後方室Rbでの潤滑油不足を解消することが可能である。   Therefore, a predetermined amount of lubricating oil is stored in each of the front chamber Ra and the rear chamber Rb during any travel described above. For this reason, it is possible to eliminate the shortage of lubricating oil in the front chamber Ra and the rear chamber Rb.

また、この実施形態では、制御弁80が、慣性弁体81と、第1弁座部材82と、第2弁座部材83を備える構成とされている。このため、ケーシング90の連通孔91aに設けられる制御弁80をシンプルに構成することができて、安価に製作することが可能である。なお、この実施形態において、第1弁座部材82と第2弁座部材83が同一形状に形成されているため、第1弁座部材(82)と第2弁座部材(83)が異なる形状に形成されている場合に比して、安価に製作することが可能である。   In this embodiment, the control valve 80 includes an inertia valve body 81, a first valve seat member 82, and a second valve seat member 83. For this reason, the control valve 80 provided in the communication hole 91a of the casing 90 can be configured simply and can be manufactured at low cost. In this embodiment, since the first valve seat member 82 and the second valve seat member 83 are formed in the same shape, the first valve seat member (82) and the second valve seat member (83) have different shapes. Compared with the case where it is formed, it can be manufactured at a low cost.

本発明は上記実施形態に限定されることはなく、本発明の範囲内において種々の変形例を採用することができる。例えば、上記実施形態では、図2に示したように、慣性弁体81をボール弁体とし、第1弁孔82aと第2弁孔83aを共に円錐台形状として、慣性弁体81が円形の第1弁座82bまたは第2弁座83bに着座したとき、潤滑油が流動しないように構成して実施したが、図4に例示したように、制御弁180の慣性弁体181をボール弁体とし、第1弁孔182aと第2弁孔183aを共に四角錐台形状として、慣性弁体181が正方形(四角形)の第1弁座182bまたは第2弁座183bに着座したとき(図5参照)、潤滑油が慣性弁体181と第1弁座182bまたは第2弁座183b間を流動するように構成して実施すること(慣性弁体が着座した状態でも所定量の潤滑油流通を許容する通路が、各弁座に設けられている構成が採用されている実施形態)も可能である。なお、図4に例示した構成に代えて、図2に示した各弁座82b、83bに慣性弁体81が着座した状態でも所定量の潤滑油流通を許容する通路(連通溝)を各弁座82b、83bに設けて実施することも可能である。   The present invention is not limited to the above embodiment, and various modifications can be employed within the scope of the present invention. For example, in the above embodiment, as shown in FIG. 2, the inertia valve body 81 is a ball valve body, the first valve hole 82a and the second valve hole 83a are both frustoconical, and the inertia valve body 81 is circular. Although it was configured so that the lubricating oil does not flow when seated on the first valve seat 82b or the second valve seat 83b, as illustrated in FIG. 4, the inertia valve body 181 of the control valve 180 is a ball valve body. When the first valve hole 182a and the second valve hole 183a are both in the shape of a truncated pyramid, and the inertia valve body 181 is seated on the first valve seat 182b or the second valve seat 183b having a square shape (see FIG. 5). ), And configured so that the lubricating oil flows between the inertia valve body 181 and the first valve seat 182b or the second valve seat 183b (allowing a predetermined amount of lubricating oil to flow even when the inertia valve body is seated) A structure is provided in which each valve seat has a passage to be Are embodiments have been) it is also possible. In place of the configuration illustrated in FIG. 4, each valve seat 82b, 83b shown in FIG. 2 has a passage (communication groove) that allows a predetermined amount of lubricating oil to flow even when the inertia valve body 81 is seated on each valve. It is also possible to provide the seats 82b and 83b.

これらの場合には、慣性弁体(181)が各弁座(182b、183b)に長時間着座し続けても、ケーシング90内の潤滑油を第1室から第2室または第2室から第1室に流動させることができて、潤滑油を両室間で流動させない場合に比して、各室内の潤滑油の温度上昇を効果的に抑えることが可能である。なお、慣性弁体が着座した状態でも所定量の潤滑油流通を許容する通路が、各弁座に設けられている構成が採用されている実施形態では、潤滑油を還流させる(戻す)通路を縦壁に設けて実施するのが望ましい。   In these cases, even if the inertia valve body (181) continues to sit on the valve seats (182b, 183b) for a long time, the lubricating oil in the casing 90 is removed from the first chamber to the second chamber or from the second chamber. It is possible to flow into one chamber, and it is possible to effectively suppress the temperature rise of the lubricating oil in each chamber as compared with the case where the lubricating oil does not flow between the two chambers. In an embodiment in which a passage that allows a predetermined amount of lubricant to flow even when the inertia valve is seated is provided in each valve seat, a passage for returning (returning) the lubricant is provided. It is desirable to carry out by providing it on a vertical wall.

また、上記実施形態では、アウトプットシャフト20に回転可能に組付けられている各変速ギヤの軸支部の潤滑については説明を省略したが、上記特許文献1(特開平11−294565号公報)に記載されている変速機と同様に、オイルポンプから供給される潤滑油にて潤滑されるように構成して実施することも可能である。   In the above embodiment, the description of the lubrication of the shaft support portion of each transmission gear that is rotatably assembled to the output shaft 20 is omitted. However, it is described in Patent Document 1 (Japanese Patent Laid-Open No. 11-294565). As in the case of the transmission, it is possible to perform the configuration by being lubricated with the lubricating oil supplied from the oil pump.

また、上記実施形態では、前進5速・後退1速の変速機に本発明を実施したが、本発明は、変速機のケーシング内が縦壁によって第1室と第2室に区画されていて、前記第1室に変速ギヤと潤滑油が収容されるとともに、前記第2室に変速ギヤと潤滑油が収容されており、前記縦壁の底部に形成した連通孔を通して前記第1室内の潤滑油と前記第2室内の潤滑油が流通可能に構成されている変速機であれば実施可能であり、例えば、前進6速・後退1速の変速機にも同様にまたは適宜変更して実施することが可能である。また、上記実施形態では、第1室と第2室が車両の前後方向に沿って配置される変速機に本発明を実施したが、第1室と第2室が車両の左右方向に沿って配置される変速機にも本発明は実施可能である。   Further, in the above embodiment, the present invention is implemented for a forward 5 speed / reverse 1 speed transmission. However, in the present invention, the casing of the transmission is partitioned into a first chamber and a second chamber by a vertical wall. The transmission chamber and the lubricating oil are accommodated in the first chamber, the transmission gear and the lubricating oil are accommodated in the second chamber, and the lubrication in the first chamber is performed through a communication hole formed in the bottom of the vertical wall. This can be implemented as long as the transmission is configured to allow oil and lubricating oil in the second chamber to circulate. For example, the transmission may be similarly or appropriately changed for a forward 6-speed / reverse 1-speed transmission. It is possible. Moreover, in the said embodiment, although this invention was implemented to the transmission with which a 1st chamber and a 2nd chamber are arrange | positioned along the front-back direction of a vehicle, a 1st chamber and a 2nd chamber are along the left-right direction of a vehicle. The present invention can also be implemented in a transmission that is arranged.
