Description

车辆用传动装置
技术领域
本发明涉及一种混合动力传动装置、自动变速器等中的车辆用传动装置，具体说是涉及一种在将来自油压泵的油压供给到变速机构部的油路中设置的单向阀。
背景技术
一般地，在以内燃机及电动马达为驱动源的混合动力传动装置中，在因信号等原因致使车辆停止时等，由于将驱动源停止，因此除了由驱动源驱动的机械式泵以外，必须有由电动马达驱动的电动泵。因此会出现机械式泵及电动泵中某一个动作而另一个停止的情况，这时，为了不使来自动作中的油压泵的油压从停止的油压泵侧漏掉，有必要在将来自油压泵的油压向油压装置供给的供给油路上设置单向阀。(日本特开2001-41066号公报)。
特别是在从机械式泵出来的供给油路上，在油压从配设于变速机构部的机械式泵向配置有调节阀等的阀体供给的关系上，上述单向阀多被配置于与收纳上述变速机构部的箱体邻接的上述阀体内。
一般地，对于上述单向阀而言，在阀体上形成的孔中收纳上述单向阀的阀芯(球体)，该阀芯受到弹簧作用而位于阀座(valve seat)上，由此流路被封堵，而通过流路中油压的作用，使阀芯克服弹簧移动，进而流体流入上述流路，但有时流入到该流路中的流体成为相对于阀芯的移动方向沿横穿的方向流动的状况。例如，在收纳有变速机构部的箱体中形成阀座的情况下，来自机械式泵的流体经过形成于上述箱体中的流路而从上述阀座流入到阀体内，克服弹簧移动上述阀芯，而在该阀体内以横穿阀芯的方式流动，由此随着与收纳阀芯的孔的间隙变大，阀芯相对于阀座偏斜。其结果，包含阀座在内上述阀芯可动并滑动连接的流路部分(以下称引导部分)产生偏磨耗，因此成为使单向阀的耐久性降低的原因，同时成为漏压的原因。
特别是，机械式泵的供给油路成为变速机构部动作的车辆行驶时的主线压油路，因此因大流量流入到上述单向阀的缘故，上述耐久性的问题较早地显现出来，压力损失变大，而还存在燃油率过低忧虑。
发明内容
因此，本发明目的在于提供一种通过利用阀芯(球体)不会与引导部分偏斜地构成的单向阀，来解决上述课题的车辆用传动装置。
技术方案1所涉及的本发明是一种车辆用传动装置(1)是具备将来自驱动源的动力变速并输出给输出轴(26)变速机构部(10)及将来自油压泵(11、12)的油压经单向阀(70)供给到上述变速机构部(10)油压装置而构成的，其特征在于，上述单向阀(70)具备：圆筒状的阀外壳(72)，其在内部形成有流路；阀芯(73)，其在上述阀外壳(72)内，以可沿该外壳的轴线方向自由移动地被收纳；阀座(72a)，其形成于上述阀外壳(72)的流路的一端部，通过落座有上述阀芯(73)来封堵上述流路；弹簧(74)，其对上述阀芯(73)施力，使之落座于上述阀座(72a)；以及弹簧座(71)，其固定于与上述阀外壳(72)的上述阀座(72a)在轴线方向上相反侧的部分并对上述弹簧(74)进行支承，
从上述阀座(72a)流入到上述阀外壳内的流体以沿着该阀外壳(72)的轴线方向流动的方式构成，且上述阀外壳内的流体的流动方向与上述阀芯(73)的可移动方向大致一致地构成。
根据上述构成，由于使用了在将阀座一体形成的阀外壳内收纳阀芯的单向阀，因此在阀外壳轴线方向上限制了阀芯的移动，并且由于流体的流动与阀芯的可移动方向大致一致，因此阀芯不会与包含阀座的引导部分(以下代表地称阀座)产生偏斜，防止了因偏斜而引起的阀座的偏磨耗，并可以延长单向阀的寿命。
在技术方案1所述的车辆用传动装置的基础上，技术方案2所涉及的本发明的上述阀芯(73)为球体，上述弹簧座(71)具有位于上述弹簧(74)的内径侧且限制上述球体移动的挡块部(75a)，上述阀外壳(72)以该外壳的长边方向亦即上述轴线方向与重力方向大致一致的方式配置而成。
根据上述构成，通过使用球体作为阀芯，并由挡块部来限制球体的可移动量，由此一方面可以顺滑地保持阀外壳内的阀芯(球体)的移动，一方面使球体的可移动方向与重力方向大致一致，因此在球体上没有作用因重力引起的偏载荷，可以更加可靠地防止球体对阀座的偏斜。
在技术方案1或2所述的车辆用传动装置的基础上，技术方案3所涉及的本发明的上述车辆用传动装置(10)为其驱动源是内燃机(2)及电马达(3、4)的混合动力车辆用传动装置，向上述油压装置供给油压的油压泵具备：被上述内燃机(2)驱动的机械式泵(11)与被电动马达驱动的电动泵(12)，上述单向阀(79)设置在供给有来自于上述机械式泵(11)油压的供给油路上而成。
根据上述构成，由于在混合动力车用传动装置的主油路亦即从机械式泵出来的供给油路上适用本单向阀，因此解决了与单向阀的耐久性相关的课题，而可以防止压力损失的增大，长期地维持较高的耗油率。
在技术方案1至3的任意一项所述的车辆用传动装置的基础上，在技术方案4所涉及的本发明中，上述油压装置具备阀体(40)，该阀体(40)内置有多个阀且具有油路，该阀体(40)配置于收纳有上述变速机构部(10)的箱体(41)的下部，在该箱体(41)固定有上述阀外壳(72)，上述单向阀(70)以其长边方向沿上下方向的方式配置于上述箱体(41)与上述阀体(40)之间。
根据上述构成，将单向阀固定于变速机构部的箱体，并在与阀体之间以使单向阀的长边方向沿上下的方式被配置，因此可以防止由阀座偏斜引起的偏磨耗的发生。
在技术方案1至4中任意一项所述的车辆用传动装置的基础上，在技术方案5所涉及的本发明中，在上述阀外壳(72)的内周面上沿着上述轴线形成有作为上述流体的流路的凹槽(72b)，上述阀芯(73)以与上述阀外壳(72)的内周面接触并可以移动地形成。
根据上述构成，由于将阀外壳的内周面上形成的凹槽作为流路，所以球体一面与阀外壳的内周面接触一面可正确地沿轴线移动，因此可以切实防止由阀座偏斜引起的偏磨耗的发生。
在技术方案5所述的车辆用传动装置(10)的基础上，在技术方案6所涉及的本发明中，设置多个上述凹槽(72b)，设置多个上述单向阀的流出口(76a，76c)。
根据上述构成，由于由多个凹槽及流出口组成，因此可以使单向阀中的流体的流动变得顺畅，且可以防止压力损失的增大。
在技术方案6所述的车辆用传动装置(10)的基础上，在技术方案7所涉及的本发明中，上述流出口是由形成于上述阀外壳(72)与上述弹簧座(75)之间的开口(76a)及形成于上述挡块部内的孔(76b)构成，且两者连接于上述凹槽(72b)。
根据上述构成，流出口是与凹槽连接的开口，因此单向阀的流体的流动很顺畅，而且在挡块部也开有孔并设为流出口，因此可以使流体的流动更加顺畅。
在技术方案1至7的任意一项所述的车辆用传动装置的基础上，在技术方案8所涉及的本发明中，具备收纳上述变速机构部的箱体，上述油压装置具备阀体(40)，该阀体(40)收纳有多个阀且具有油路，上述单向阀(70)与上述阀体(40)分体构成，并且上述阀外壳(72)固定于收纳有上述变速机构部(10)的箱体(41)而形成。
根据上述构成，单向阀由与阀体为不同部件构成，并且固定于收纳有自动变速机构部的箱体，因此在将阀体组装于上述外壳时，可以防止阀外壳内的油量的偏移。
另外，上述括号内的符号用于与附图相对照用，并不会因此而影响到专利申请范围的构成。

以下，参照图1至图4，对本发明所涉及的实施方式进行说明。
首先利用图1对适用于本发明的混合动力传动装置(车辆用传动装置)的构成进行说明，则在本混合动力传动装置1中，变速机构部10的输入轴17经未图示的减震装置连接于引擎2的曲轴2a，单一行星齿轮亦即动力分配用行星齿轮5的行星架CR1经轮毂部件18连接于该输入轴17。该行星架CR1具有小齿轮P1，该小齿轮P1由未图示的侧板被旋转自由地支承。在与该小齿轮P1啮合的太阳齿轮S1上连接有第1马达3的转子轴19。此外，上述小齿轮P1上连接有内齿圈R1，在该内齿圈R1上连接有圆筒状的支承部件20，并且经该支承部件20连接于传递轴21。
另一方面，具有行星齿轮组件6a的有级变速装置6连接于传递轴21的后端侧(图中右方侧)，具体地说，行星齿轮组件6a的行星架CR2经轮毂部件22连接于传递轴21。该行星架CR2具有由未图示的侧板被旋转自由地支承的长小齿轮P2、P4与短小齿轮P3(以下，简称小齿轮P3)，该长小齿轮中，小径部分的小齿轮P2与大径部分的小齿轮P4被一体形成，小齿轮P3啮合于该小径部分的小齿轮P2。
太阳齿轮S2啮合于小齿轮P3，第2马达4的转子轴23连接于该太阳齿轮S2。另外，太阳齿轮S3与上述小齿轮P4啮合，轮毂部件24连接于该太阳齿轮S3。多板式制动器亦即第一制动器B1的摩擦板经花键接合于该轮毂部件24，该第1制动器B1通过供给有来自调节阀的管路油，而形成自由卡止。
另外，内齿圈R2啮合于上述小齿轮P3，多板式制动器亦即第2制动器B2的摩擦板经花键卡合于该内齿圈R2，该第2制动器B2通过供给有来自调节阀的管路油，而形成自由卡止。
并且，上述传递轴21连接于作为变速机构部10的输出轴26，该输出轴26经未图示的联接器或传动轴等连结于差速装置，还从该差速装置经左右驱动轴连接于构成后车轮的驱动车轮16、16。
为了使这些变速机构10动作，或对各滑动部进行润滑，而利用作为引擎2的动力的机械式油泵11来向内置有调节阀等各阀的阀体40供给油压，还在上述混合动力传动装置1中，设置与机械式油泵11不相关而独立驱动的电动油泵12。该电动油泵12由电动马达13驱动，该电动马达13供给有来自电动油泵用变换器的电力。对于该电动油泵12而言，由于例如引擎2在怠速停止或在起动时等的停止状态下，与该引擎2连动的机械式油泵11也停止，因此主要是在该机械式油泵11处于停止状态下才被驱动，来确保油压控制装置的油压的机构。
该机械式油泵11与电动油泵12并列连接于油压控制装置，因此例如机械式油泵11停止中电动油泵12动作的情况下，由电动油泵12产生的油压向机械式油泵11逆流，无法给予油压控制装置所必须的油压。作为该问题的对策，为了防止油压向机械式泵11的逆流，油压单向阀70成为必要。
接着对本发明所涉及的单向阀70(逆流防止阀)的构成进行详细说明。图2是将混合动力传动装置10的一部分放大来表示单向阀70剖面的图，单向阀70以其轴线与重力方向大致相同的方式被定位并配置于阀体40中，该阀体40被配置在变速箱41的下部，由机械式油泵11加压的油经箱体41内的油路(未图示)供给到单向阀70的上部。被加压的油压缩弹簧74，且压低位于图中的单向阀70的上部的阀芯亦即球体73，由此，在阀外壳72的阀座(valve seat)72a与球体73之间产生间隙，从而形成供油流动的路径。
另一方面，机械式油泵侧路径相对于油压控制装置处于相对负压的情况下，油从图中的单向阀下部流入，由此单向阀70的球体73与油的流动连动并与阀外壳72的阀座72a抵接，油流动路径被截断而可以防止油的逆流。
结合图3对该油的流动路径进行说明，则来自油压回路的从返回路径流入的油30与经过滤器从油盘吸上来的油31被导入到并列连接的机械式油泵11及电动油泵12。在两泵11、12中的任意一个泵动作，例如因怠速停止而机械式泵11停止、电动泵12动作的情况下，电动泵12使油流向与吐出口连接的单向阀32，而供给到作为油压负荷侧的调节路径33及润滑路径34。
另一方面，在该油的流动回路中，由于除通向负荷侧的供给路径33、34之外，还分支有经单向阀70及停止中的机械式泵11而朝向原来油流入路的短路路径，所以以防止油流入该短路回路为目的，通过夹设起到一通阀的作用的单向阀70来防止油压回路的短路。
接着，对单向阀70的机构进行说明。图4(A)是单向阀70的侧面方向的剖视图，图4(B)是将单向阀70沿A-A线切断的俯视剖视图，图4(C)是将单向阀70沿B-B线切断的俯视剖视图。单向阀70由如下构件构成，即：圆筒状的阀外壳72，其在内部形成流路；球体73，其在阀外壳72的内部，可沿着其长边方向亦即轴线方向滑动地配置；阀座(valve seat)72a，其形成于阀外壳72的流路的一端部，通过球体73落座而封堵流路；弹簧74，其以使球体73落座到阀座72a的方式进行施力；以及弹簧座71，其固定于上述阀外壳72的与阀座72a沿轴线方向相反的一侧。
对于阀外壳72而言，在其上部外周上形成有螺纹72c，并通过该螺纹72c与形成于变速箱41的油压供给油路开口部的内螺纹(未图示)螺合而被固定，而且该阀外壳72被插入到在该阀外壳72的下部构成有阀体40的油压供给油路的开口孔中。另外，箱体41的油压供给油路开口部与阀体40的油压供给油路开口部油密状接合，另外，阀外壳72的凸缘72d与箱体41油密状接合。此外，在该阀外壳72被安装状态下，单向阀70以其长边方向亦即轴线方向与重力方向大致一致的方式配置。在阀外壳72的上部形成有流入口72f和球体73所抵接的阀座72a，通过球体73的移动形成油密状态或油可通过状态。另外，在阀外壳72的内周面上，从阀座72a的下部到阀外壳72的末端，直线地形成有多道(3道)沿轴向的凹槽72b。该凹槽72b是将从阀座72a流入的油导入到阀外壳72末端的油路，同时在凹槽72b之间形成有与阀外壳72呈同心圆状且可对球体73进行滑动支承的支承部72e。利用这些凹槽72b与支承部72e，除形成油路之外，还可以限制球体73的移动，以使其仅在轴线方向上沿阀外壳72的径中心可自由移动，就能够使球体73的轴心与阀座72a的座面的轴心总保持同心地进行落座。另外，由于凹槽72b形成为油路，因此将其设为直线状并且尽量增大其横截面积从减少损失抵抗的观点来看是有利的，故而优选为设置多道凹槽72b，或增大一道凹槽72b的横截面积。另一方面，由于支承部72e必须对阀芯73向阀外壳72内的径向移动进行限制，因此有必要通过至少3个点以上的接触点来与球体73的周面抵接。该凹槽72b的面积与支承部72c的个数成相反关系，应当从油通过损失抵抗与阀芯73的移动容易度出发进行适当选择。
接着，阀芯73有必要在阀外壳72内滑动且与阀座72a抵接并做成油密状态，因此优选为球状球体，但只要可以形成油密状态，则可以采用将抵接面设为平面的圆柱，将抵接面设为斜面的圆锥或圆盘状的平板。然而为了不阻碍油流动的线路且降低损失抵抗，优选地，采用球体形状。此外，球体73经支承于台座71的弹簧74向阀座72a施加作用力，在通常状态下球体73与阀座72a相抵接，只有在施加有克服作用力方向的力的时候阀芯73滑动而形成油路。
弹簧74的一端的端部与设置于弹簧座71的弹簧座部75抵接，同时以覆盖挡块75a的外周的方式被配置，且被支承为只能在弹簧74的压缩方向上移动。另一方面，球体73克服重力抵接于弹簧74的另一端的端部，随着弹簧74的移动阀芯73在上下方向移动。弹簧74的作用力由弹簧线半径与缠绕数决定，因此以可以发挥使阀芯73与阀座72a抵接的最小限度作用力的方式来决定线半径与缠绕数。
接着，弹簧座71从阀外壳72的下端与球体73、弹簧74一起插入到阀外壳72的内部，与阀外壳72的内周亦即支承部72e嵌合并成为一体，即使被施加有在阀外壳72的内部动作的油压力的情况下，也不会解除嵌合。另外，在弹簧座71上具有比台座所具有的外径小的弹簧座部75及从该弹簧座部75延伸出来的圆柱状的挡块部75a。弹簧座部75如上所述成为弹簧74的抵接面，另外，在挡块部75a的上端部具有限制球体73上下移动的顶部，阀芯73被限制为只在阀座72a与挡块部75a顶部之间移动，故而可以防止在阀外壳72内较大的滑动。另外，包含阀座72a在内，从该阀座72a到由上述挡块部75a所限制的内壁面的范围是球体73滑动并有可能使阀外壳72产生偏磨耗的引导部分。另外，在挡块部75a中，贯通台座71且使半径中心朝向轴向的穿孔76d被形成直到挡块部75a的顶部附近，并形成后述的油路。在挡块部75a的侧部形成有贯通孔76b，该贯通孔76b用于将经过阀外壳72的凹槽72b的油引导到穿孔76d。
经流入口72f从阀座72a与球体73的间隙漏出并流入到阀外壳72内的油，其中一部分经过阀外壳72的凹槽72b从相当于凹槽72b下端的流出口76a流到阀外壳72外，一部分经设于挡块部75a的贯通孔76b被引导到穿孔76d，并从存在于弹簧座71的下端的流出口76c流到阀外壳72的外部。由此，油的流出路径不仅具有流出口76b、76c两条路径，还可以直线地形成油路径，因此流入到阀外壳72内的油可以毫无损失地被引导到外部，因此可以将单向阀70处产生的压力损失控制在最小限度。
另外，在本实施方式中，对设置在从机械式油泵出来的供给油路中的单向阀进行了说明，其也可以适用于设置在从电动泵出来的供给油路中的单向阀，另外，作为车辆传递装置，适用于混合动力传动装置，但并不限于此，还可以同样地适用于自动变速机等其他车辆用传动装置。
本发明设置于车辆用传动装置的油循环路径中，用来防止油逆流。
