Description

車輛動力傳送裝置
[0001] 本發明關於一種車輛動力傳送裝置，其具有旋轉軸，旋轉軸傳送來自驅動力源之驅動力並且經由錐形滾子軸承可旋轉地支撐，同時在外殼構件中之其旋轉中心線方向加壓，較特別的是關於增進可旋轉地支撐旋轉軸的錐形滾子軸承的防卡死性能之技術。
[0002] 眾所周知車輛動力傳送裝置具有旋轉軸，其傳送來自驅動力源之驅動力並且經由錐形滾子軸承可旋轉地支撐，同時在作為外殼構件的傳動軸箱中之其旋轉中心線方向預負載（加壓）。例如，日本專利申請案公告2013-124742（JP 2013-124742 A）號中揭述之車輛驅動裝置即此車輛動力傳送裝置。 　　[0003] 日本專利申請案公告2013-124742（ JP 2013-124742 A）號中揭述之車輛驅動裝置之傳動軸箱例如備有圓柱形主體外殼及端蓋，端蓋將引擎側上之主體外殼之開口封閉。用於傳送來自驅動力源之驅動力的旋轉軸的一端係經過錐形滾子軸承而由對應於傳動軸箱之一端表面的上述端蓋可旋轉地支撐。此外，引擎固接至形成於凸條之頂部上的組裝表面，凸條經由板件而直接或間接設於端蓋之外表面上。
[0004] 附帶一提，具有頂表面供組裝表面形成於其上的凸條係比其他部分厚，因此有加強肋條的功能。惟，基於車輛驅動裝置及類似者小型化之理由，設於端蓋外表面上之凸條部分可以配置成通過旋轉軸之旋轉中心線附近。在此情況中，關於經由錐形滾子軸承可旋轉地支撐且同時在旋轉中心線方向預負載（加壓）之旋轉軸，當固定組件，例如引擎直接或經由板件而間接固定在形成於凸條頂表面上之組裝表面上時，在其旋轉中心線方向施加於旋轉軸的預負載不必要地增加。因此，可旋轉地支撐旋轉軸之錐形滾子軸承之防卡死性能即惡化。特別是當低溫時，由於錐形滾子軸承與輕合金製成之傳動軸之間的熱膨脹係數差異所致之上述預負載更為增加，因此上述防卡死性能惡化便大有可能。 　　[0005] 本發明在以其頂表面供待固定於固定組件之匹配表面形成於其上的凸條部分係形成於上述車輛動力傳送裝置之外殼構件之端表面上之旋轉軸之旋轉中心線附近的情況下，可以抑制錐形滾子軸承之防卡死性能惡化。 　　[0006] 就本發明之一態樣而言，一種車輛動力傳送裝置，包括：錐形滾子軸承；驅動力源；外殼構件，包括端部表面，該端部表面包括設有第一組裝表面的凸條，該凸條之部分設置於該端部表面上，以致使該凸條之該部分通過和該錐形滾子軸承之外滾道相對應的區域；旋轉軸，傳送來自該驅動力源之驅動力，該旋轉軸係在該旋轉軸之圓周方向經由該錐形滾子軸承旋轉支撐，同時在該外殼構件中之該旋轉軸之旋轉中心線方向加壓，且該旋轉軸之一端部係經由該錐形滾子軸承以該外殼構件之該端部表面以旋轉方式支撐；該驅動力源固定於該第一組裝表面的固定狀態，其係該驅動力源經由固定組件固定於該第一組裝表面的狀態、及該驅動力源直接固定於該第一組裝表面的狀態的其中一個；及凹部，設置於該第一組裝表面、及用於固定該驅動力源的其他組裝表面的至少其中一個內，在和該錐形滾子軸承之該外滾道相對應的該區域中，該其他組裝表面設置於該固定組件及該驅動力源的其中一個。 　　[0007] 根據上述車輛動力傳送裝置，凸部局部設置在凸條上所形成之第一組裝表面及用於固定驅動力源的其他組裝表面的至少其中一個內，並且在和錐形滾子軸承之外滾道相對應的區域中。因此，藉由固定組件固接在凸條上所形成之第一組裝表面，面對面之組裝表面之間的間隙即在形成凹部的區域中擴大。當預負載因固接固定組件或到達低溫以及固接固定組件而增加時，包括外殼構件之端部表面上旋轉中心線通過之位置的區域即逸入擴大之間隙中。因此，施加於錐形滾子軸承之預負載即受限，使得錐形滾子軸承之防卡死性能不致惡化。 　　[0008] 就本發明之另一態樣而言，該驅動力源經由該固定組件固定於該第一組裝表面，該固定組件係板形組件，其介置於該驅動力源與該外殼構件之該端部表面之間，該板形組件包括在該外殼構件之側面處面向該第一組裝表面的第二組裝表面、及設置於該驅動力源之側面處的第三組裝表面，該驅動力源包括在該板形組件之側面處面向該第三組裝表面的第四組裝表面，及該凹部設置於該第一組裝表面、該第二組裝表面、該第三組裝表面、及該第四組裝表面的至少其中一個內。 　　[0009] 根據上述車輛動力傳送裝置，固定組件係板形組件，其介置於驅動力源與外殼構件之端部表面之間。面向凸條上所形成之第一組裝表面的第二組裝表面係形成於板形組件之外殼構件側上，且面向驅動力源上所形成之第四組裝表面的第三組裝表面係形成於板形組件之驅動力源側上。凹部形成於第二組裝表面、第三組裝表面、及第四組裝表面的至少其中一個內。依此方式，凹部形成於外殼側上之第二組裝表面、驅動力源側上之第三組裝表面、及形成於驅動力源側上之第四組裝表面的至少其中一個內。因此，藉由板形組件固接在凸條上所形成之第一組裝表面，及藉由驅動力源固接在板形組件之驅動力源側上之第三組裝表面，面對面之組裝表面之間的間隙即在形成凹部的區域中擴大。當預負載因固接固定組件與驅動力源或到達低溫以及固接固定組件與驅動力源而增加時，包括外殼構件之端部表面上由旋轉中心線所通過之位置的區域即逸入擴大之間隙中。 　　[0010] 就本發明之一態樣而言，該驅動力源直接固定於該第一組裝表面，該驅動力源包括在該外殼構件之側面處面向該第一組裝表面的第四組裝表面，及該凹部設置於該第一組裝表面及該第四組裝表面的至少其中一個內。 　　[0011] 根據上述車輛動力傳送裝置，面對面之組裝表面之間的間隙係在形成凹部的區域中擴大。當預負載因固接驅動力源或到達低溫以及固接驅動力源而增加時，包括外殼構件之端部表面上由旋轉中心線所通過之位置的區域即逸入擴大之間隙中。 　　[0012] 該凹部之深度可為100至300mm。 　　[0013] 根據上述車輛動力傳送裝置，當預負載因固接驅動力源或到達低溫以及固接驅動力源而增加時，包括外殼構件之端部表面上旋轉中心線通過之位置的區域即逸入擴大之間隙中。再者，組裝表面之間的間隙不致於擴大超出所需，故可維持密封性能。
[0015] 驅動力源較佳為一備有單向離合器之引擎，單向離合器可防止曲柄軸反向旋轉。一差動齒輪裝置容置於車輛動力傳送裝置之一外殼構件中。差動齒輪裝置備有供引擎耦合之第一旋轉元件、耦合於第一電動馬達之第二旋轉元件、及耦合於第二電動馬達之第三旋轉元件。板形組件為單向離合器之一定子。在此情況下，當引擎不運轉時，第一電動馬達及第二電動馬達兩者可同時具有驅動力源之功能。 　　[0016] 在形成於凸條上之組裝表面、固定組件之外殼側上之組裝表面、固定組件之驅動力源側上之組裝表面、及形成於包括旋轉軸旋轉中心線所通過之位置之區域中之驅動力源上之組裝表面上的凹部較佳形成於其他組分下方100mm至數百mm深度處。在此情況下，當預負載因固接驅動力源或到達低溫以及固接驅動力源而增加時，包括外殼構件之端部表面上由旋轉中心線所通過之位置的區域即逸入擴大之間隙中。再者，組裝表面之間的間隙並未擴大到超過所需，因此密封性能仍得以維持。較佳在組裝表面之間***一可變形之高黏度流體，像是密封劑、迫緊件、墊片或類似者，或是固體密封構件。 　　[0017] 根據本發明之各實施例之用於混合動力車輛的動力傳送裝置將參考圖式詳細說明於後。附帶地，在本發明之下列實施例中，圖式係適度做部分簡化或變形，且個別組件之尺寸比、形狀及類似者未必做精確表示。 　　[0018] 本發明之實施例即參考圖式詳細說明於後。 　　[0019] 圖1係概略圖，舉例說明一混合動力車輛的動力傳送裝置10（文後簡稱為「動力傳送裝置10」）之一組構，作為供本發明較佳施加之車輛之部分。圖1所示之動力傳送裝置10較佳使用於前置引擎前輪驅動式（FF）車輛，並且建構成主要備有設於作為驅動力源之引擎12（主動力源）與一對右左驅動輪14l及14r（文後簡稱為驅動輪14，特別是在其無法彼此區別的情況中）之間的動力傳送路徑中的第一驅動單元16、第二驅動單元18、及一對右及左輪軸22r及22l。 　　[0020] 引擎12例如為一內燃機，像是汽油引擎、柴油引擎、或類似者，其中驅動力係經由噴入汽缸內之燃料燃燒而產生。此外，第一驅動單元16建構成備有一行星式齒輪裝置24，行星式齒輪裝置具有三旋轉元件，亦即，一太陽齒輪S、一載具CA、及一環形齒輪R，以及耦合於行星式齒輪裝置24之太陽齒輪S的第一電動馬達MG1。此外，一單向離合器F0設置於一作為引擎12之輸出軸的曲柄軸26與一作為非旋轉構件的傳動軸箱（外殼構件）50之間，用於防止引擎12反向旋轉，同時容許引擎12正向旋轉。據此，引擎12即藉由單向離合器F0防止反向旋轉。 　　[0021] 引擎12之曲柄軸26經由第一驅動單元16之一輸入軸19耦合於行星式齒輪裝置24之載具CA。此外，曲柄軸26耦合於一機械式油泵30。此外，作為一輸出旋轉構件的行星式齒輪裝置24之環形齒輪R則耦合於一輸出齒輪32。附帶地，輸出齒輪32耦合於驅動輪14，以致使動力可經由一差動齒輪裝置20及輪軸22傳送至此。此外，行星式齒輪裝置24之太陽齒輪S耦合於第一電動馬達MG1。亦即，行星式齒輪裝置24相當於一耦合於引擎12之曲柄軸26並且備有載具CA、太陽齒輪S、及環形齒輪R的差動機構。載具CA耦合於單向離合器F0並且使用作為第一旋轉元件RE1。太陽齒輪S耦合於第一電動馬達MG1並且使用作為第二旋轉元件RE2。環形齒輪R係輸出旋轉構件並且使用作為第三旋轉元件RE3。 　　[0022] 輸出齒輪32嚙合於一大直徑齒輪36，大直徑齒輪係與一平行於曲柄軸26（作為第一驅動單元16之一輸入軸）的副從動軸（旋轉軸）34形成為一體。此外，一依相同方式與副從動軸34形成為一體的小直徑齒輪38係嚙合於差動齒輪裝置20之一環形齒輪40。此外，大直徑齒輪36嚙合於第二輸出齒輪44，第二輸出齒輪耦合於具有一驅動型電動馬達功能的第二電動馬達MG2的一輸出軸42。亦即，第二電動馬達MG2耦合於驅動輪14，以致使動力可傳送至此。在此應該注意的是，第一電動馬達MG1及第二電動馬達MG2各具有馬達-發電機之功能，亦即兼具用於產生驅動力之馬達（驅動力源）及用於產生反應力之發電機（電動發電機）的功能。 　　[0023] 在依上述建構之動力傳送裝置10中，在第一驅動單元16中從引擎12輸出之旋轉係從輸出齒輪32經過作為差動機構的行星式齒輪裝置24輸出，並且經過設在副從動軸34上的大直徑齒輪36及齒數較少於大直徑齒輪36者的小直徑齒輪38，以輸入至差動齒輪裝置20之環形齒輪40。在此應該注意的是從輸出齒輪32輸出之旋轉是以預定之減速比減速，減速比係由大直徑齒輪36之齒數與小直徑齒輪38之齒數決定，並且該旋轉輸入至差動齒輪裝置20之環形齒輪40。此外，差動齒輪裝置20具有習知主減速齒輪之功能。 　　[0024] 此外，根據組構，第一電動馬達MG1在第一驅動單元16中之旋轉係經過行星式齒輪裝置24傳送至輸出軸32，並且經過設在副從動軸34上的大直徑齒輪36及小直徑齒輪38傳送至差動齒輪裝置20之環形齒輪40。此外，根據組構，第二電動馬達MG2在第二驅動單元18中之旋轉係經過輸出軸42及第二輸出齒輪44傳送至設在副從動軸34上的大直徑齒輪36，並且經過大直徑齒輪36及小直徑齒輪38傳送至差動齒輪裝置20之環形齒輪40。亦即，根據本發明之實施例之動力傳送裝置10係建構以致使引擎12、第一電動馬達MG1、及第二電動馬達MG2各可使用作為一用於運轉之驅動源。 　　[0025] 根據本發明之實施例之動力傳送裝置10備有傳動軸箱50，其具有外殼構件功能，用於容置一具有上述四軸線組構之齒輪組。附帶地，圖1之概略圖中所示之齒輪為斜齒輪。 　　[0026] 傳動軸箱50係由例如將鋁壓鑄件彼此耦合取得之圓柱形主體外殼54、用於將引擎12側上之主體外殼54之開口封閉的第一端蓋56、及用於將引擎12側之相反側上之主體外殼54之開口封閉的第二端蓋58構成，諸組件經由一預定密封材料以液密式彼此耦合。第一端蓋56及第二端蓋58設有軸孔60l及60r，以容許輪軸22l及22r個別通過。此外，第一端蓋56備有一輸入軸貫穿孔21，供輸入軸19通過。 　　[0027] 圖2揭示一狀態，其中具有旋轉軸功能並且傳送作為驅動力源之引擎12之驅動力的副從動軸34係經由傳動軸箱50中之一對錐形滾子軸承62及64可旋轉地支撐。填隙片66及68係在副從動軸34之旋轉中心線C方向***錐形滾子軸承62之外滾道62a與第一端蓋56之間、及錐形滾子軸承64之外滾道64a與主體外殼54之間。在旋轉中心線C方向之一預設強度之預負載施加於副從動軸34及可旋轉地支撐副從動軸34的該對錐形滾子軸承62及64。 　　[0028] 圖3係一視圖，揭示在引擎12側上之傳動軸箱50之一端部表面，亦即第一端蓋56。此外，圖4係一視圖，揭示在引擎12側之相反側上之傳動軸箱50之一端部表面，亦即第二端蓋58。在圖3及4之各圖中，旋轉中心線C上之一區域，亦即對應於可旋轉地支撐副從動軸34之該對錐形滾子軸承62及64之外滾道62a及64a之外徑D的區域A，其藉由一長短線交替之圓表示。上述旋轉中心線C通過此區域A之中心。此區域A係一局部承受旋轉中心線C方向之預負載之作用力的部位。 　　[0029] 如圖3中所示，為了經由一螺栓並藉由圖5之一固定板（固定組件）70將引擎12固定於第一端蓋56，一使用作為環形凸條並且具有一平坦組裝表面（第一組裝表面）F1形成於其頂點上的肋條72係形成於第一端蓋56上之輸入軸貫穿孔21周圍。此肋條72通過由長短線交替之圓表示的區域A內部，例如區域A之中心或其附近。此肋條72朝向引擎12側突出、局部厚度加大、及亦具有強化第一端蓋56之功能。固定板70係板形組件，其相當於一固定在第一端蓋56之固定組件，並且具有例如單向離合器F0之定子的功能。 　　[0030] 在圖5中，一相似於組裝表面F1之環形平坦組裝表面（第二組裝表面）F2形成於第一端蓋56側上之固定板70之一表面的一外周邊厚部上。組裝表面F1及F2彼此組裝成緊密接觸狀態，並在其間夾置一預定之密封材料。此外，一相似於在圖6之引擎12上形成之一組裝表面（第四組裝表面）F4的環形平坦組裝表面（第三組裝表面）F3係形成於引擎12側上之固定板70之一表面的一外周邊厚部上，亦即圖5之固定板70之後表面。組裝表面F3及F4彼此組裝成緊密接觸狀態，並在其間夾置一預定之密封材料。 　　[0031] 在本發明之較佳實施例中，一局部凹部74形成於一長方形區域B中，長方形區域在沿著肋條72之方向上包括區域A並以虛線表示，局部凹部亦形成於在第一端蓋56側上之圖5之固定板70表面之外周邊厚部上所形成的組裝表面F2中。如圖中所示，例如圖7，凹部74具有在組裝表面F2之其他部位下方例如100至300 mm的深度。圖7是以展開方式揭示沿著組裝表面F2之寬度方向之一中心線的圖5之VII-VII截面。 　　[0032] 圖8揭示一局部形成於固定板之組裝表面上的凸出量（板厚度凸出量）與施加於一對錐形滾子軸承62及64之預負載之增加量之間的關係。凹部74之深度設定成當預負載之增加量為最大時即使在低溫下使用，預負載之增加量不會導致錐形滾子軸承62及64之防卡死性能惡化。 　　[0033] 圖9及10各為示意圖，揭示凹部74之操作及效果。圖9為示意圖，揭示在未設置凹部74之情況下，在傳動軸箱50、固定板70、及引擎12之一組裝狀態中之預負載如何隨著各黑色箭頭之大小增加而增加。圖10為示意圖，揭示在設置凹部74之情況下，在傳動軸箱50、固定板70、及引擎12之一組裝狀態中之預負載如何隨著各黑色箭頭之大小增加而增加。 　　[0034] 在圖9中，就傳動軸箱50單獨而言，傳動軸箱50之第一端蓋56係因施加於錐形滾子軸承62及64之預負載而朝向引擎12側略為彈性變形。在此狀態中，當固定板70及引擎12固定於第一端蓋56之組裝表面時，第一端蓋56係在其彈性變形量減少的方向受壓，使得預負載相對應地增加。再者，當環境溫度低到例如大約-30℃時，上述預負載即因傳動軸箱50之材料（鋁合金）與副從動軸34及可旋轉地支撐副從動軸34之一對錐形滾子軸承62及64之材料（鋼材）之間的熱膨脹差異而進一步增加。此預負載增加導致防卡死性能惡化。 　　[0035] 在圖10以及圖9中，就傳動軸箱50單獨而言，傳動軸箱50之第一端蓋56係因施加於錐形滾子軸承62及64之預負載而朝向引擎12側略為彈性變形。在此狀態中，即使固定板70及引擎12固定於第一端蓋56之組裝表面時，第一端蓋56之彈性變形係由凹部74維持，使得預負載之增加受限。再者，當環境溫度低到例如大約-30℃時，上述預負載即因傳動軸箱50之材料（鋁合金）與副從動軸34及可旋轉地支撐副從動軸34之一對錐形滾子軸承62及64之材料（鋼材）之間的熱膨脹差異而進一步增加，但是在組裝時預負載之增加則受限。因此，結果是當低溫時，預負載之增加比圖9中的狀態更受限。 　　[0036] 如上所述，藉由本發明之實施例之動力傳送裝置10，凹部74局部沿著肋條72之方向設置在固定板（固定組件）70之組裝表面F2中，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中。因此，藉由固定板70固定於在肋條（凸條）72上所形成之組裝表面F1，面對面之組裝表面F1及F2之間的間隙是在形成凹部74的區域B中擴大。據此，當錐形滾子軸承62及64之預負載因固定板70之固定或達到低溫以及固定板70之固定而增加時，包括區域A（對應於傳動軸箱（外殼構件）50之端表面上之錐形滾子軸承62之外滾道62a之外徑D）的區域B可以逸入擴大之間隙內。因此，施加於錐形滾子軸承62及64之預負載即受限，使得錐形滾子軸承62及64之防卡死性能不致惡化。 　　[0037] 接著，本發明之另一實施例將揭述於後。附帶地，在發明之下列實施例中，和發明之上述實施例共同的組件將個別以相同參考編號表示，並且不予以贅述。 　　[0038] 圖11揭示第一端蓋56，亦即在引擎12側上根據本發明實施例之傳動軸箱50之端部表面。圖7所示之凹部74局部設置於平坦組裝表面F1中，平坦組裝表面形成於根據本發明實施例之第一端蓋56之肋條72之頂點上，並且在沿著肋條72之方向之包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中，亦即，在沿著第一組裝表面F1之方向。 　　[0039] 在本發明之實施例中，圖6所示之引擎12直接固定於第一端蓋56之組裝表面F1。圖7所示之凹部74沿著肋條72之方向形成於此引擎12之組裝表面F4中，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中，亦即，在沿著第四組裝表面F4之方向。 　　[0040] 藉由根據本發明實施例之車輛動力傳送裝置10，引擎12直接固定於第一端蓋56，且凹部74形成於第一端蓋56之肋條72之頂點上所形成之第一組裝表面F1及引擎之組裝表面F4（等於第二組裝表面）的各者中。如本文內所述，凹部74沿著肋條72之方向形成於第一端蓋56之組裝表面F1及引擎之組裝表面F4的各者中，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中。因此，組裝表面F1及F4之間的間隙（相當於和錐形滾子軸承62之外滾道62a對應的區域A）即擴大。因此，當預負載因達到低溫以及引擎12固定而增加，同時引擎12藉由引擎12之組裝表面F4與第一端蓋56之組裝表面F1彼此緊密接觸而固定於傳動軸箱50，由於預負載而從傳動軸箱50之端部表面突出的區域A可以適當逸入上述擴大間隙內。 　　[0041] 本發明已參考圖表及圖式詳細說明。惟，本發明亦可在此範圍內進入許多替換且不悖離其主旨。 　　[0042] 例如，藉由根據本發明之上述第一實施例之動力傳送裝置10，凹部74局部沿著肋條72之方向設置在固定板70之組裝表面F2中，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中。此外，藉由根據本發明之上述第二實施例之動力傳送裝置10，凹部74局部沿著肋條72之方向設置於肋條（凸條）72上所形成之組裝表面F1及引擎12之組裝表面F4的各者中，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中。惟，凹部74可以形成於肋條（凸條）72上所形成之組裝表面F1或固定板70之組裝表面F3上的類似位置。簡而言之，凹部74可局部設置於肋條（凸條）72上所形成之組裝表面F1、固定板70之組裝表面F2、固定板70之組裝表面F3、及引擎12之組裝表面F4的至少其中一個內，並且在包括區域A（對應於錐形滾子軸承62之外滾道62a）的區域B中。
此外，本發明之上述實施例之凹部74設置於包括區域A(對應於錐形滾子軸承62之外滾道62a)的區域B中的組裝表面F1、F2、F3及F4中。區域B較佳設定成在沿著肋條72之方向上大於區域A，但是區域B應該設定比區域A大多少或是沿著肋條72之哪一方向應該選擇作為區域B相關於區域A而延伸的方向，則應根據局部設置於第一端蓋56上的厚部。
此外，在本發明之上述實施例中，將引擎12固定於傳動軸箱50的車輛動力傳送裝置10已揭述於上。惟，引擎12並非絕對固定於傳動軸箱50。也可以使用一將轉速箱固定作為一固定組件的傳動軸箱或類似者。
此外，多數個固定板70可***傳動軸箱50與引擎12之間。
附帶地，上述說明並未超越本發明之實施例，且本發明之實施例亦無其他舉例。惟，本發明可以基於此技術範圍內之習於此技者的認知而進行許多替代型式及改良，此並未悖離其主旨。
