Description

带双动力路径和选择性电机连接的混合电动变速器
技术领域
[0001]本发明涉及混合电动变速器,其带有两个电机/发电机,其中一个可选择性地连接到五节点复合差动齿轮组的两个不同的齿轮元件,另一个也可连接到一个不同的齿轮元件,用来提供电动可变输入分离操作模式。
背景技术
[0002]混合电动变速动力系统包括发动机和变速器,所述变速器从发动机和一个或者多个电机/发电机接收功率通量。混合电动变速器有差动齿轮组,来自发动机和电机/发电机的动力流动通过不同的差动齿轮组元件。混合电动变速器可包括扭矩传输机械装置,其可根据各种接合表接合来提供操作模式组合,包括电动可变范围和固定的齿轮传动比。电动可变范围典型地提供平稳的操作情况下,最适宜的发电机速度,同时固定的齿轮传动比保证在特定的情况下,例如持续的高速路巡航时,最大的扭矩实现和最大的燃料燃烧效率。电动可变范围经由机电动力路径所建立,其中,通过电机/发电机使从发动机输出的一小部分动力转化为电力,然后再由电机/发电机转化成机械动力。通过直接将电机/发电机和发动机连接在一起,固定的齿轮传动比典型地提供卓越的变速器输出扭矩和车辆加速度。在固定的齿轮传动比下,从变速器输入元件到变速器输出元件的动力流动路径视为完全地通过机械动力路径,因为速度没有通过电机/发电机改变。
发明内容
[0003]包括两个电机/发电机的混合电动变速器提供动力分离,电动可变动力沿着双动力路径流动,而且提供多种的操作模式,包括电动可变输出分离模式。变速器还包括带五个齿轮元件的差动齿轮组(例如,复合差动齿轮组通过五节点杆图描述)。第一电机/发电机与其中一个齿轮元件连接,第二电机/发电机单独地可选择性地与另外两个齿轮元件连接。当第二电机/发电机与两个齿轮元件都连接的时候,一个固定的速度比被建立,因此,需要锁止离合器以便通过差动齿轮组获得一个固定的速度比。
[0004]在这里,“齿轮元件”是差动齿轮组的一个元件,可以被一个在杆图里的节点所描述。例如,在行星齿轮组中,行星架元件,太阳轮元件和一个齿圈元件都可以被作为杆图里的节点所描述,但是被行星架构建支撑的小齿轮不能作为节点描述。同样,在复合行星齿轮组中,这些连续地和另外的一个元件互相联接齿轮元件可以通过一个单独的节点被描述。本领域技术人员很容易理解将混合差动齿轮组描述为杆图。
[0005]在这里,“模式”是一种特定的操作状态,不论包括连续速度比范围或者仅仅一个固定的速度比,通过特定的扭矩传输装置或者扭矩传输装置组合获得的。
[0006]变速器包括适合从发动机获得动力的输入元件和输出元件。输入元件与第一齿轮元件连接以共同旋转,并且第一电机/发电机与第二齿轮元件连接以共同旋转。变速器进一步包括互相啮合齿轮,至少其中一个可与输出组件连接作旋转。第一电机离合器选择性地接合第二电机/发电机和第三齿轮元件。第二电机离合器选择性地接合第二电机/发电机和第四齿轮元件。第一和第二传输元件,最好是轴,被连接以与第四和第五齿轮元件共同转动,并且分别地,通过接合不同的输出扭矩传输装置,经由不同的互相啮合的齿轮中的一个,可单独地运转连接输出组件。因此,第一和第二传输组件部分地在输入元件和输出元件之间形成第一和第二动力路径。
[0007]通过将不同的电机离合器组合和输出扭矩传输装置接合,可获得多种可能的操作模式。例如,电动可变输入分离模式是通过将第二电机离合器和连接第四齿轮元件和输出元件的输出扭矩传输装置中的一个接合而被建立的。复合分离操作模式通过将第一电机离合器和与在电力可变输入分离操作模式中相同的输出扭矩传输装置接合而被建立。如果两个电机离合器和同样的输出扭矩传输机械装置被接合,则固定比率模式被建立,因为两个电机离合器的接合锁上差动齿轮组,所以所有齿轮元件以同样的速度转动。
[0008]在一个实施例里,互相啮合齿轮包括多个齿轮组,这些齿轮组经由中间轴从传输元件到输出元件传输扭矩。其中一个齿轮组可能是反向齿轮组,具有一个齿轮与输出组件连接以共同转动,一个齿轮与中间轴连接以共同转动,而且一个反向或者怠速齿轮与其它两个齿轮相互啮合。第二电机离合器和反向输出离合器的接合连接与输出轴共同转动的齿轮,来实现输入分离电动可变模式。如果有三个另外的齿轮组,并且三个附加输出扭矩传输装置选择性地接合来分别沿着这些组件从中间轴传输扭矩,则除电动可变输入分离反向模式之外,这个实施例获得一个电动可变输入分离前向模式,三个电动可变复合分离模式和五个固定前进比率模式。
[0009]在另一个实施例里,互相啮合的齿轮是一个简单的行星齿轮组,带有被连接以与第一传输组件共同转动的第一组件,被连接以与输出元件共同转动的第二组件,和经由其中一个输出扭矩传输装置选择性地连接到静止组件的第三组件。输出扭矩传输装置同样包括离合器,所述离合器选择性地连接第五齿轮元件到输出元件上。该实施例获得一个电动可变输入分离模式,两个电动可变输入分离模式和三个固定比率模式。
[0010]本发明的上述特点和优势以及其它特点和优势可以从下面结合附图的对实现本发明的最好方法的细节描述中很容易获得。
附图说明
[0011]图1是在本发明范围内的包括第一变速器的第一动力系统的示意图。
[0012]图2是在本发明范围内的包括第二变速器的第二动力系统的示意图。
具体实施方式
第一实施例
[0013]参考附图,其中类似的附图标记对应类似的构件,图1表示车辆11的动力系统10(示意性地表示)。动力系统10包括发动机12,其与数字14所指示的电动变速器(EVT)的一个实施方式连接。变速器14设计为从发动机12接收至少一部分驱动功率。发动机12具有输出轴连接变速器14的输入组件16。终端驱动单元17可操作地与变速器14的输出组件19连接。
[0014]变速器14包括复合差动齿轮组20。差动齿轮组20是一种Ravigneaux型齿轮组,尽管其它类型的差动齿轮组也可在本发明的范围内使用。特定地,差动齿轮组20包括太阳轮组件22,齿圈组件24和行星架组件26,所述行星架组件26旋转支撑与太阳轮组件22、齿圈组件24、第二套小齿轮28互相啮合的第一套小齿轮27。行星架组件26同样旋转支撑第二套小齿轮28,它与太阳轮组件32和齿圈组件34、第一套小齿轮27互相啮合。本领域技术人员将意识到,差动齿轮组20可用五节点杆图描述,每个杆图的节点描述下述齿轮元件:太阳轮组件22、太阳轮组件32、行星架组件26、齿圈组件24和齿圈组件34。在权利要求中,行星架组件26被称为第一齿轮元件,太阳轮组件22被称为第二齿轮元件,太阳轮组件32被称为第三齿轮元件,齿圈组件34被称为第四齿轮元件,齿圈组件24被称为第五齿轮元件。
[0015]输入组件16连续地与行星架组件26连接。第一电机/发电机40A连续地与太阳轮组件22连接。齿圈组件24和34行使差动齿轮组的两个单独输出元件的作用,部分地形成两个单独的动力路径通过变速器14,如下文中将讨论的。
[0016]电机/发电机40A包括定子部分42A,其固定在静止的组件44上,例如变速箱壳。电机/发电机40A的转子46A经由套轴47连续地与太阳轮组件22连接。定子42A可接收电力动力从或者提供动力到能量贮存设备48例如电池。电子控制器50和电池48信号通信,而且功率转换器52和定子部分42A也电子通信。控制器50响应输入信号的变化,包括车辆速度,操作者要求,电池48的充电情况和发动机12所提供的动力,用来通过换流器52控制在电机/发电机40A和电池48之间动力流量,所述换流器在供给电池48或由电池48所使用的直流电和供给定子部分42A或由定子部分42A使用的交流电之间转换。
[0017]第二电机/发电机40B包括定子部分42B,其固定在静止组件44上。通过接合第一电机离合器MC1,电机/发电机40B的转子部分46B选择性地连接太阳轮组件32。通过接合第二电机离合器MC2,转子部分46B也选择性地与齿圈组件34连接。通过与上文描述的定子部分42A同样的方式,控制器50和换流器52有效地与定子部分42B连接。
[0018]变速器14进一步包括传输组件56、58,中间轴60和个互相啮合的齿轮,所述齿轮选择性地经由中间轴连接传输组件56、58和输出组件,下文中将描述。齿圈组件24连续地与传输组件58连接。齿圈组件34连续地与传输组件56连接。
[0019]互相啮合的齿轮包括由齿轮62和齿轮64组成的互相啮合的齿轮组。齿轮62被连接以与传输组件56共同转动,并且啮合齿轮64,齿轮64与中间轴60连接以共同转动。啮合齿轮进一步包括由啮合齿轮66、68、70组成的反向齿轮组。齿轮66围绕中间轴60同心转动,并且通过选择性地接合输出离合器OCR,可与其共同转动。齿轮68随着输出组件19转动。反向齿轮70与齿轮66、68都啮合,所以齿轮66和68在同一个方向转动。啮合齿轮70被单独的轴或者支撑结构(没有显示)支撑,而且围绕平行于传输组件56、58和中间轴60的轴线转动。啮合齿轮进一步包括由啮合齿轮72和74组成的齿轮组。齿轮72随着输出组件19转动。齿轮74与齿轮72互相啮合,并且通过选择性地接合输出离合器OC3,可与其共同转动。啮合齿轮进一步包括由啮合齿轮76和78组成的齿轮组。齿轮76随着输出组件19转动。齿轮78与齿轮76互相啮合,并且通过选择性地接合输出离合器OC1,可与其共同转动。
[0020]除了输出离合器OC1,OC3和OCR,输出离合器OC2可选择性地接合以连接传输组件58和齿圈组件24以与输出组件19共同转动。因此,变速器14包括四个输出离合器(OC1,OC2,OC3和OCR)和四个中间轴齿轮组(齿轮组62,62;齿轮组68,70,66;齿轮组72,74;齿轮组76,78)。
[0021]扭矩传输装置MC1,MC2,OC1,OC2,OC3和OCR可操作地与控制器50连接(通过传输导体连接,为简化起见没有显示),所述控制器50在其中控制它们的接合以提供多种操作模式,包括电动可变输入复合分离(前进)模式,三种电动可变复合分离前进模式,电动可变输入分离反向模式和五种固定比率,下文中将描述。
[0022]通过接合电机离合器MC2和输出离合器OC1,变速器14在电动可变输入分离模式里能操作用于低输出速度。电机/发电机40B与传输组件56和齿圈组件34连接(通过接合MC2),进而可操作地与输出组件19经由齿轮组62、64和齿轮组76、78连接(通过接合输出离合器OC1)。扭矩也可以通过发动机12提供,通过差动齿轮组20到输出组件56。当输出组件19的速度从0提高而发动机速度不变并且非零时,也就是当变速器宿弊降低时,齿圈组件34的速度从零开始升高,太阳轮组件22的速度下降并且然后到0,而且太阳轮组件32的速度升高,设想正向速度与输出组件19的正向转动在相同的方向上。
[0023]在电动可变输入分离前进模式时期的一些点上,通过接合电机离合器MC1,电机/发电机40B能与太阳轮组件32连接,并且通过释放电机离合器MC2,能与齿圈组件34分离。在电机/发电机40B与太阳轮组件32连接的时候,通过分别接合每一个输出离合器OC1,OC2和OC3,变速器14能够在三种不同的电动可变复合分离(前进)模式下操作。也就是说,第一电动可变复合分离(前进)模式通过接合MC1和输出离合器OC1被建立,第二电动可变复合分离(前进)模式通过接合电机离合器MC1和输出离合器OC2被建立,第三电动可变复合分离(前进)模式通过接合电机离合器MC1和输出离合器OC3被建立
[0024]在电动可变输入分离或者复合分离模式下,电机/发电机40A或者40B可作为电机增加传递给变速器14的扭矩。如果刹车发生在这些模式下,则电机/发电机40A或者40B被控制作为发电机将太阳轮组件22或32中的一个的旋转速度(在复合分离模式中)分别地由电机转子46A或46B转换成贮存在电池48的电力,吸收转矩以此帮助降低输出组件19的速度并且使车辆11制动。类似地,电机/发电机40A和40B可被控制以通过作为发电机给电池48再充电。
[0025]-一个电动可变输入分离换向模式通过接合电机离合器MC2和输出离合器OCR被建立。电机/发电机40B与传输组件56和齿圈组34连接(通过接合MC2),进而可操作地与输出组件19经由齿轮组62、64和反向齿轮组66、70、68连接(通过接合输出离合器OCR)。扭矩也可以通过发动机12提供,通过差动齿轮组20到传递组件56。
[0026]变速器14能以五种不同的固定比率操作。例如,在从电机离合器MC2和输出离合器OC1被接合的电动可变输入分离模式到电机离合器MC1和输出离合器OC1被接合的电动可变复合分离模式的转换中,两者在上文中都有描述,如果当输出离合器OC1接合的时候电机离合器MC1和MC2两者都接合,将会得到一个固定的齿轮比,因为差动齿轮组20将会锁定并且所有组件在同一速度下转动。因此,电机离合器MC1和MC2可以操作来代替行星齿轮组20的单独的锁止离合器。电机离合器MC1和MC2都接合并且输出离合器OC2接合能获得第二固定比率。电机离合器MC1和MC2都接合并且输出离合器OC3接合能获得第三固定比率。通过接合两个输出离合器OC1和OC2,在电机离合器MC1接合的复合分离操作过程中,能获得第四固定比率,所述离合器OC1和OC2的接合将会引起不同传输组件56和58,并因此齿圈元件24和34在同一速度下转动。类似地,当电机离合器MC1被接合的时候,通过接合输出离合器OC2和OC3将会获得第五固定比率。
[0027]动力系统10提供几种仅电动的操作模式,其中动力仅通过电机/发电机40A、40B提供,比如接通发动机启动,发动机关闭反向驱动,和发动机关闭前进驱动。接通发动机启动和空转操作模式通过接合两个电机离合器MC1、MC2获得。电能从电池48供给到电机/发电机40A和40B,所述电机/发电机40A和40B用作电机使太阳轮组件22、32在同一方向上转动。行星架组件56、58相对自由地转动,由于没有一个输出离合器OC1、OC2、OC3和OCR接合,因此输出组件19不转动。小齿轮27、28由于太阳轮组22、32而转动,并且引起行星架组件26,以及由此引起输入组件16转动。这进而引起发动机输出组件(连接变速器输入组件16)转动,转动发动机以启动发动机12。
[0028]固定的反向速比通过接合两个电机离合器MC1、MC2和输出离合器OCR获得。在这种布置下,行星齿轮组20的所有组件和输入组件16以及电机/发电机40A和40B以同样的速度转动。扭矩经由齿轮组62、62,反向齿轮组(齿轮66,反向齿轮70和齿轮68),和中间轴60传输到输出组件19。
[0029]例如,通过当电机/发电机40A供给机械动力到太阳轮组件22时,只接合输出离合器OCR,获得仅电动的反向模式。小齿轮27、28分别地供给机械动力到齿圈组件24、34。齿圈组件34提供转动速度到中间轴60和反向齿轮组(齿轮66,反向齿轮70和68)。反向齿轮70使转动方向反向,因此齿轮68与齿轮66以同样的速度和同样的方向转动。
[0030]第一和第二动力路径(齿圈组件34和传输组件56形成第一动力路径,齿圈组件24和传输组件58形成第二动力路径)在变速器14里被提供。第二动力路径当输出离合器OC2接合的时候使用。第一动力路径当任何一个离合器OCR、OC1或者OC3接合的时候使用。
第二实施例
[0031]参考附图,其中类似的附图标记对应类似的构件,图2表示车辆111的动力系统110(示意性地表示)。动力系统110包括发动机112,其与数字114所指示的电动变速器(EVT)的一个实施方式连接。变速器114设计为从发动机112接收至少一部分驱动功率。发动机112具有输出轴连接变速器114的输入组件116。终端驱动单元117可操作地与变速器114的输出组件119连接。
[0032]变速器114包括复合差动齿轮组120。差动齿轮组120是一种Ravigneaux型齿轮组,尽管其它类型的差动齿轮组也可在本发明的范围内使用。特定地,差动齿轮组120包括太阳轮组件122,齿圈组件124和行星架组件126,所述行星架组件126旋转支撑与太阳轮组件122、齿圈组件124、第二套小齿轮128互相啮合的第一套小齿轮127。行星架组件126同样旋转支撑第二套小齿轮128,它与太阳轮组件132和齿圈组件134、第一套小齿轮127互相啮合。本领域技术人员将意识到,差动齿轮组120可用五节点杆图描述,每个杆图的节点描述下述齿轮元件:太阳轮组件122、太阳轮组件132、行星架组件126、齿圈组件124和齿圈组件134。在权利要求中,行星架组件126被称为第一齿轮元件,太阳轮组件122被称为第二齿轮元件,太阳轮组件132被称为第三齿轮元件,齿圈组件134被称为第四齿轮元件,齿圈组件124被称为第五齿轮元件。
[0033]输入组件116连续地与行星架组件126连接。第一电机/发电机140A连续地与太阳轮组件122连接。齿圈组件124和134行使差动齿轮组的两个单独输出元件的作用,部分地形成两个单独的动力路径通过变速器114,如下文中将讨论的。
[0034]电机/发电机140A包括定子部分142A,其固定在静止的组件144上,例如变速箱壳。电机/发电机140A的转子部分146A经由套轴147连续地与太阳轮组件122连接。定子142A可接收电力动力从或者提供动力到能量贮存设备148例如电池。电子控制器150和电池148信号通信,而且功率转换器152和定子部分142A也电子通信。控制器150响应输入信号的变化,包括车辆速度,操作者要求,电池148的充电情况和发动机112所提供的动力,用来通过换流器152控制在电机/发电机40A和电池148之间动力流,所述换流器在供给电池148或由电池148所使用的直流电和供给定子部分142A或由定子部分142A使用的交流电之间转换。
[0035]第二电机/发电机140B包括定子部分142B,其固定在静止组件144上。通过接合第一电机离合器MC1,电机/发电机140B的转子部分146B选择性地连接太阳轮组件132。通过接合第二电机离合器MC2,转子部分146B也选择性地与齿圈组件134连接。通过与上文描述的定子部分142A同样的方式,控制器150和换流器152可操作地与定子部分142B连接。
[0036]变速器114进一步包括传输组件156、158和个互相啮合的齿轮,所述齿轮选择性地连接传输组件156、158和输出组件119,下文中将描述。齿圈组件24连续地与传输组件58连接。齿圈组件134连续地与传输组件156连接。
[0037]互相啮合齿轮是带有太阳轮组件162,行星架组件165和齿圈组件169的行星齿轮组。行星架组件165旋转地支撑一套小齿轮167,所述小齿轮与太阳轮组件162和齿圈组件169都啮合。太阳轮组件162经由传输组件或轴156被连续地连接以与齿圈组134共同转动。行星架组件165连续地与输出组件119连接。
[0038]变速器114包括输出扭矩传输装置,包括输出离合器OC和输出制动器OB。输出离合器OC选择性地接合以经由传输组件158连接齿圈组件124到两个传输组件165和输出组件119。输出制动器OB选择性地接合以将齿圈组件169固定到到变速器箱144上。
[0039]扭矩传输装置MC1、MC2、OC和OB可操作地连接到控制器150上(通过传递导体连接,为简化起见未显示),控制器控制它们的接合以提供多种操作模式,包括电动可变输入分离(前进模式),两个电动可变复合分离前进模式和三个固定前进比率模式,下文中将描述。
[0040]通过接合电机离合器MC2,变速器114能在电动可变输入分离模式下运行作低输出转速。因此电机/发电机140B与行星架组件156和齿圈组件134连接,进而可操作地与输出组件119通过太阳轮组件162、小齿轮127和传送组件165连接。扭矩也可以由发动机112通过差动齿轮组120到传输组件156提供。
[0041]在电动可变输入分离前进模式下,在一些点上,电机/发电机140B能通过接合电机离合器MC1连接太阳轮组件132,而且通过释放电机离合器MC2从齿圈组件134分离。在电机/发电机140B连接到太阳轮组132时,通过分别接合输出离合器OC和输出制动器OB,变速器114能在两种不同电动可变复合分离(前进)模式下运行。第一电动可变复合分离(前进)模式通过接合电机离合器MC1和输出离合器OC被建立,第二电动可变复合分离(前进)模式通过接合电机离合器MC1和输出制动器OB被建立。
[0042]在电动可变输入分离或者在电动可变复合分离模式下,电机/发电机140A或者140B作为电机增加传递到到变速器114的扭矩。如果这些模式下出现制动情况,则电机/发电机140A或者140B被控制作为发电机以分别转换太阳轮组件122或132(在复合分离模式下)的转动速度,而且分别通过电机转子146A或146B贮存电力到电池148,吸收扭矩降低输出组件119的速度并且使车辆111制动。类似地,电机/发电机140A或者140B可被控制作为发电机来为电池148再充电。
[0043]变速器114能在三个不同的固定比率模式下运行。例如,在从电机离合器MC2和输出离合器OC被接合的电动可变输入分离模式到电机离合器MC1和输出离合器OC被接合的电动可变复合分离模式的转换中,当输出离合器OC被接合的时候,如果两个电机离合器MC1和MC2被接合,则将会获得固定齿轮比模式,因为差动齿轮组120将被锁定同时所有组件在同一个速度下转动。因此,电机离合器MC1和MC2被操作用来代替行星齿轮120的单独的锁止离合器。
[0044]第二固定比率模式在电机离合器MC1、MC2都被接合并且输出制动器OB被接合的时候获得。第三固定比率模式在通过接合输出离合器OC和输出制动器OB电机离合器MC1被接合的复合分离操作模式的过程中获得,因为这将引起传输组件156和158并因此齿圈组件124和134以同样的速度转动。
[0045]动力系统110提供仅电动的操作模式,在其中动力仅通过电机/发电机140A、140B提供,例如发动机启动和发动机只向前驱动。在怠速操作模式下发动机启动通过接合两个电机离合器MC1、MC2来实现。电能从电池148供给电机/发电机140A、140B,所述电机/发电机140A、140B用作电机以在相同的方向转动两个太阳轮组件122、132。传输组件156、158相对自由地转动,因为输出扭矩传输装置OC、OB都未被啮合,因此输出组件119不转动。小齿轮127、128由于太阳轮组件122、132而转动,并且引起行星架组件126以及由此输入组件116转动。这进而引起发动机输出组件(被连接到变速器输出组件116上)转动,转动发动机112以启动发动机112。
[0046]例如,通过操作电机/发电机140A作为电机以经由太阳轮组件122和小齿轮127、128提供扭矩到齿圈组件134,仅电动的前进模式被实现。齿圈134经由传输组件156、太阳轮组件162和行星架组件165提供扭矩到输出组件119。
[0047]第一和第二动力路径(齿圈组件124和传输组件158作为第一动力路径,齿圈组件134和传输组件156作为第二动力路径)在变速器114里被提供。第一动力路径每当输出离合器OC被接合的时候使用。第二动力路径每当输出制动器OB被接合的时候使用。
[0048]尽管实现发明的最好的模式已经被详细描述,然而本发明相关领域技术人员将会意识到为实践本发明的多种可选择的设计和实施例都在所附加的权利要求范围内。
