本发明涉及一种根据权利要求1的前序部分的、用于混合动力机动车的混合动力动力传动系。
背景技术

发明内容
本发明的目的在于提供一种混合动力动力传动系,其以相比于现有技术在构造上简单、结构空间有利的结构具有在功能性上更大的自由度。
该目的通过权利要求1的特征实现。在从属权利要求中公开了本发明的有利的改进方案。
根据权利要求1的特征部分,第一子变速器T1的齿轮平面E1、V4中的一个构造为第一混合齿轮平面E1。第二子变速器T2的齿轮平面E2、V3中的一个构造为第二混合齿轮平面E2。两个混合齿轮平面E1、E2可借助于切换元件K1、K2、SE-E、SE-D附加地分别与电机的电机轴传动连接。
在技术上的实施方案中,混合齿轮平面E1、E2中的至少一个可由布置在传动轴上的从动侧齿轮、布置在输入轴上的驱动侧齿轮以及布置在电机轴上的齿轮组成。布置在电机轴上的齿轮可作为浮动齿轮以可转动方式支承在电机轴上,并且可借助于切换元件K1、K2从电机轴脱开或与之联接。
优选的是,电机轴完全不具有以不可相对转动的方式布置在其上的圆柱齿轮组固定齿轮,该圆柱齿轮组形成变速器的齿轮平面。
此外,优选的是,变速器设计为纯粹的圆柱齿轮变速器,在其中输入轴、传动轴、电机轴和输出轴可以仅仅通过圆柱齿轮组彼此传动连接。以这种方式实现简单建造的变速器结构,其可相比于行星齿轮变速器效率更高地运行。
在一优选的实施方式中,相应的混合齿轮平面E1、E2可与其他齿轮平面V3、V4一起布置在第一子变速器T1和第二子变速器T2中。相比于相应的混合齿轮平面E1、E2,上文提到的其他齿轮平面V3、V4相对于电机轴不存在连接,并且具有以可转动方式支承在传动轴上的从动侧的浮动齿轮,其可借助于切换元件SE-D、SE-E与传动轴联接。优选的是,布置在传动轴上的切换元件SE-D、SE-E可在两侧切换,并且沿轴向方向布置在混合齿轮平面E1、E2的以可转动方式支承在传动轴上的从动侧的浮动齿轮与其他齿轮平面V3、V4之间。
上文提到的其他齿轮平面V3、V4还可以具有布置在相应的输入轴上的驱动侧的固定齿轮。
布置在电机轴上的切换元件可任意地实现,例如实现为可动力切换的双离合器。此外,电机可在驱动侧或从动侧连接在变速器中。在驱动侧的连接中,混合齿轮平面E1、E2的电机侧齿轮可与布置在相应的输入轴上的驱动侧的固定齿轮啮合。在从动侧的连接中,混合齿轮平面E1、E2的电机侧齿轮可与混合齿轮平面E1、E2的以可转动方式支承在传动轴上的从动侧的浮动齿轮啮合。
除非例如存在明显的相关性或存在不兼容的替代方案,本发明的在上文阐述的和/或在从属权利要求中说明的有利的设计方案和/或改进方案可单独地使用或任意组合地使用。
附图说明
下面借助附图详细阐述本发明和它有利的构造方案、改进方案以及它的优点。其中:
具体实施方式
在图1中示出了具有双离合变速器1的混合动力动力传动系,其示例性地构造为4挡双离合变速器。混合动力动力传动系为未示出的混合动力机动车的组成部分。双离合变速器1可借助于切换元件切换到不同的传动级中,并且由圆柱齿轮组组成,该圆柱齿轮组形成齿轮平面E2、V3、E1、V4。齿轮平面E1、V4分配给第一子变速器T1,而齿轮平面E2、V3分配给第二子变速器T2。两个子变速器T1、T2具有公共的传动轴17。子变速器T1、T2中的每个分别具有单独的输入轴37、43。在输入轴中,第一输入轴37实施为实心轴,其同轴地穿过实施为空心轴的第二输入轴43。两个输入轴37、43可分别通过可动力切换的离合器LK1、LK2交替地与同内燃机7连接的内燃机轴3连接,在该内燃机轴中集成有扭转减振器5。附加地,电机11可借助于随后说明的切换元件K1、K2、SE-E、SE-D与双离合变速器1连接。
电机11可为了扭矩转换而具有在图1中示出的前置行星传动机构12。此外,变速器1在输出侧通过输出轴13与机动车的前桥VA传动连接。输出轴13作为小齿轮轴与前桥差速器15的锥齿轮传动机构作用连接。
如图1另外所示,内燃机轴3、电机轴9以及布置在中间的传动轴17彼此轴线平行。传动轴17、电机轴9以及输出轴13可通过圆柱齿轮组彼此传动连接,该圆柱齿轮组可通过切换元件切换。圆柱齿轮组形成彼此平行布置的齿轮平面E2、V3、E1、V4,它们在图1中沿轴向方向全部处在内燃机7与电机11之间。
下面说明在图1中示出的双离合变速器1的变速器结构:于是,在图1中,第一输入轴和第二输入轴37、43以及传动轴17可通过四个齿轮平面E2、V3、E1、V4彼此连接,它们相应由彼此啮合的浮动齿轮和固定齿轮组成。
总共四个齿轮平面E2、V3、E1、V4具有两个混合齿轮平面E1、E2。每个混合齿轮平面E1、E2具有布置在传动轴17上的从动侧的浮动齿轮19、21,其分别与布置在相应的输入轴37、43上的驱动侧的固定齿轮23、25并且分别与电机侧的浮动齿轮27、29啮合。
双离合变速器1的两个子变速器T1、T2可彼此独立地在变速器运行中完全切换到无力矩状态,即,完全与动力传动系分离,从而第一子变速器T1或第二子变速器T2完全停止运转。在第一子变速器T1中,包括第一混合齿轮平面E1和直接轴向相邻的另一齿轮平面V4。在第二子变速器T2中,包括第二混合齿轮平面E2以及直接相邻的另一齿轮平面V3彼此联合在一起。
布置在第一子变速器T1中的齿轮平面V4具有以可转动方式支承在传动轴17上的从动侧的浮动齿轮33。齿轮平面V4的从动侧的浮动齿轮33和第一混合齿轮平面E1的从动侧的浮动齿轮19可通过布置在它们之间的可在两侧切换的切换元件SE-D交替地与传动轴17联接。齿轮平面V4具有驱动侧齿轮35,其作为固定齿轮布置在第一输入轴37上。
第二子变速器T2与第一子变速器T1构造相同。在第二子变速器T2中,齿轮平面V3具有以可转动方式支承在传动轴17上的从动侧的浮动齿轮39。齿轮平面V3的从动侧的浮动齿轮39和第二混合齿轮平面E2的从动侧的浮动齿轮21可通过布置在它们之间的可在两侧切换的切换元件SE-E交替地与传动轴17联接。第二混合齿轮平面E2以及齿轮平面V3具有以不可相对转动的方式布置在第一输入轴43上的固定齿轮25、41。
如由图1进一步得知的那样,混合齿轮平面E1、E2的两个同轴于电机轴9布置的电机侧齿轮27、29通过双离合器来切换,该双离合器由第一离合器K1和第二离合器K2组成。双离合器具有外膜片载体45,其以不可相对转动的方式与电机轴9连接。外膜片载体45与两个沿轴向方向并排布置的内膜片载体47、49共同作用。内膜片载体49与第一混合齿轮平面E1的电机侧齿轮27一起以不可相对转动的方式布置在空心轴51上。与此相对地,内膜片载体47与第二混合齿轮平面E2的电机侧齿轮29一起以不可相对转动的方式布置在实心轴53上,该实心轴同轴地穿过空心轴51。
在图1中示出的双离合变速器1总共具有12个齿轮、两个同步器以及四个动力切换的离合器K1、K2、LK1、LK2。在变速器1中可切换出多达8个内燃机驱动的挡位,即,下文阐述的四个内燃机驱动的径直挡VM1至VM4,它们利用仅仅一个齿轮平面;以及四个曲径挡VM5至VM8,它们利用至少两个齿轮平面:
在径直挡VM1和VM3中,动力切换的离合器LK2接合,即,激活了子变速器T2,并且切换元件SE-E向左或向右切换,而子变速器T1停止运转。在径直挡VM2和VM4中,动力切换的离合器LK1接合,即,激活了子变速器T1,并且切换元件SE-D向左或向右切换,而子变速器T2停止运转。
对于以下的四个内燃机驱动的曲径挡VM5至VM8,在挡位VM5中,动力切换的离合器LK2、K1以及K2接合,并且切换元件SE-D向右切换。由此得到这样的负荷路径,其从第二输入轴43通过第二混合齿轮平面E2、实心轴53、两个接合的离合器K1、K2伸延至第一混合齿轮平面E1,并且进一步通过第一输入轴37以及齿轮平面V4伸延至传动轴17。在内燃机驱动的曲径挡VM6中,除了切换元件SE-D向左切换之外,切换元件相同地切换。
在内燃机驱动的曲径挡VM7中,动力切换的离合器LK1、K1和K2接合,并且切换元件SE-E向右切换。由此得到这样的负荷路径,其从第一输入轴37通过第一混合齿轮平面E1、空心轴51、两个接合的离合器K1、K2伸延至第二混合齿轮平面E2,并且进一步通过第二输入轴43以及齿轮平面V3伸延至传动轴17。在内燃机驱动的曲径挡VM8中,除了切换元件SE-E向左切换之外,切换元件相同地切换。
在纯电机驱动的运行中,在图1中示出的变速器1可切换出以下的两个径直挡EM1、EM2以及两个曲径挡EM3和EM4:
因此,在径直挡EM1中,操纵离合器K1,并且切换元件SE-D向左切换。在径直挡EM2中,操纵离合器K2,并且切换元件SE-E向左切换。在电机驱动的曲径挡EM3中,操纵离合器K1,并且SE-D向右切换。在曲径挡EM4中,操纵离合器K2,并且SE-E向右切换。
如由上文的说明得知的那样,内燃机驱动的曲径挡可由此产生:使两个电机侧的离合器K1、K2接合。相反,电机驱动的曲径挡可由此产生:相应向右操纵布置在传动轴17上的切换元件SE-E和SE-D中的一个。
由上文的内燃机驱动的挡位VM1至VM8和电机驱动的挡位EM1至EM4可组合地实现混合挡位,在其中组合地切换出电机驱动的挡位和内燃机驱动的挡位。例如,下文说明了一种行驶情况,在其中挂入内燃机驱动的径直挡VM2或VM4。在该情况下,电机11可在以下的四个不同的连接方案中与变速器连接:
在第一连接方案中,动力切换的离合器K2接合,并且切换元件SE-E向左操纵。因此,在形成径直挡的情况下,电机11通过混合齿轮平面E2驱动传动轴17。
在第二连接方案中,动力切换的离合器K2接合,并且切换元件SE-E向右操纵。由此得到这样的负荷路径,其从电机11通过实心轴53、第二混合齿轮平面E2、第二输入轴43、齿轮平面V3、切换元件SE-E伸延至传动轴17。因此,在形成曲径挡的情况下,电机11驱动传动轴17。
在第三连接方案中,动力切换的离合器K1接合。由此得到这样的负荷路径,其从电机11通过空心轴51以及第一混合齿轮平面E1伸延至传动轴17。
在第四连接方案中,除了已经接合的离合器LK1之外,使离合器LK2和K2接合。由此得到这样的负荷路径,其从电机11通过实心轴53、第二混合齿轮平面E2、两个接合的离合器LK2、LK1伸延至第一输入轴37。
此外,只要车辆处于车辆停车状态中,例如在交通信号灯处或在堵塞中,通过在图1中示出的变速器结构实现电机11的驻车充电。此外,借助于电机11可执行内燃机起动。电机11可通过这样的负荷路径使内燃机7起动,在其中例如第二离合器K2(其包括外膜片载体45和内膜片载体47)接合,以及仅仅动力切换的离合器LK2接合。
