Description

混合动力变速器
技术领域
本发明涉及一种具有至少一个电机和至少一个离合器的混合动力变速器。
背景技术
由德国的专利申请文件DE 10 2011 115 078 A1已知一种混合动力变速器，该混合动力变速器作为在与内燃机连接的驱动轴，电池和从动轴之间的功率转换器和特性变扭器，其中，混合动力变速器具有第一电动机和第二电动机，第一电动机和第二电动机通过功率控制单元相互连接并且与电池连接，并且其中，混合动力变速器具有多轴的行星齿轮装置，用于叠加来自两个电动机的、来自内燃机的和来自从动轴的功率流，其中，所述多轴的行星齿轮装置是四轴的行星齿轮装置，其中第一轴直接或经由另外的传动级连接到第一电动机的转子，其中第二轴能够经由第一离合器直接地或经由另外的传动级连接到第二电动机的转子，其中第三轴能够经由第一制动器与变速器壳体连接，并且其中第四轴与混合动力变速器的从动轴连接，其中所述第二电动机能够经由第二离合器与驱动轴连接，其中所述第三轴能够经由第三离合器与驱动轴连接。
发明内容
本发明所要解决的技术问题是，在所需的结构空间方面，特别是轴向结构空间方面，优化具有至少一个电机和至少一个离合器的混合动力变速器。
该技术问题在具有至少一个电机和至少一个离合器的混合动力变速器中被这样解决，即在电机的径向内侧并且沿轴向完全与电机的转子重叠地布置离合器。混合动力变速器优选布置在机动车的混合动力驱动系中。在混合动力驱动系中，电机优选构成副驱动装置。主驱动装置例如由混合动力驱动系中的内燃机构成。混合动力变速器优选是能够自动地或手动地操作的换挡变速器。离合器优选是具有两个分离合器的双离合器。根据本发明的离合器的布置方式提供了这样的优点，即能够设计电机的转子具有较大的轴向尺寸。轴向是指混合动力变速器的变速器输入轴的旋转轴线的方向或与其平行的方向。有利地，通过离合器与电机的转子的节省空间的组合，能够通过集成的大功率电机实现轴向结构较短的混合动力变速器。在具有混合动力驱动系的机动车中的较小的结构空间能够通过上述离合器的布置方式得到充分的利用。
混合动力变速器包括固定轮和活动轮，固定轮和活动轮能够通过联接装置和/或同步器与传动轴抗扭地连接，以传递扭矩。摆动地或旋转地，优选在活动轮中的至少一个的径向外侧设计联接装置和/或同步装置。摆动的或旋转的操作能够以不同的方式进行。例如，摆动操作或旋转操作能够包括行星齿轮传动，与变速器输入轴同轴的摆动或旋转运动通过该行星齿轮传动转换成同步器部件(例如滑动套筒或换挡套筒)的轴向运动。然而，摆动操作运动或旋转操作运动还能够借助至少一个套筒状的引导体和螺杆机构转换成同步器部件(例如滑动套筒或换挡套筒)的轴向运动。优选地，在两个相邻的活动轮的径向内侧并且沿轴向与两个活动轮重叠地布置联接装置和/或同步器，以优化结构空间。由此，能够以简单的方式和方法优化地利用在活动轮内侧的可用空间，以使传动轴与活动轮中的一个同步。有利地，用于施加摆动或旋转运动的操作件沿轴向延伸穿过两个相邻的活动轮的齿部之间并向径向外侧延伸。在这种情况下，能够借助合适的(例如包括电动机的)执行器产生摆动或旋转的操作运动并且例如通过小齿轮施加。在这种情况下，摆动操作或旋转操作与传动轴同轴或同心地进行，两个相邻的活动轮布置在该传动轴上。
混合动力变速器的优选实施例的特征在于，在电机的径向内侧并且沿轴向完全与电机的转子重叠地布置附加的分离离合器。有利地，通过附加的分离离合器，电机能够与主驱动装置，特别是内燃机分离。附加的分离离合器用于在混合动力变速器中实现P2-混合动力装置。
混合动力变速器的另外的优选实施例的特征在于，混合动力变速器包括两个变速器输入轴，一个变速器输出轴和具有两个分离合器的双离合器，在电机的径向内侧并且沿轴向完全与电机的转子重叠地布置两个分离合器。有利地，变速器输入轴中的一个被设计为空心轴，其中抗扭地布置第二变速器输入轴。两个分离合器分别与变速器输入轴中的一个相配属。平行于两个变速器输入轴地布置变速器输出轴。在混合动力变速器中，本身已知的双离合变速器与电机组合。通过摆动或旋转操作，结合离合器在电机的转子的径向内侧以及沿轴向与电机的转子重叠的布置方式，能够优化地利用轴向的结构空间。
能够设计离合器(即双离合器的分离合器)和附加的分离离合器湿式运行。如果设计离合器湿式运行，那么有利地设计离合器为多片式离合器。也能够设计离合器干式运行。混合动力变速器能够包括双质量飞轮，双质量飞轮有利地用于从变速器中消除例如由用作主驱动装置的内燃机引起的扭转不均匀性。在电机的较大的设计中，其惯性矩已经具有减振作用。有利地，还能通过电机主动减少非均匀性。有利地，电机的转子与离合器部件连接或联接，离合器部件例如是所有离合器(即双离合器的分离合器和附加的分离离合器)的外离合器片支架或压板。
混合动力变速器的另外的优选实施例的特征在于，通过一个或多个离合器，与至少两个齿轮平面，优选四个齿轮平面相邻地布置电机，在齿轮平面中分别布置固定轮和活动轮，固定轮和活动轮为构成换档级借助联接装置实现同步，能够通过旋转或摆动操作件旋转地或摆动地操作联接装置。用于操作联接装置的旋转运动或摆动运动与变速器输入轴中的至少一个，优选与两个变速器输入轴同心地或同轴地进行。特别地，在传统的具有换档拨叉的操作装置中，操作运动不是沿轴向施加的。通过旋转或摆动操作，混合动力变速器的变速器长度能够显著减小，特别有利地比传统混合动力变速器减小百分之三十到六十。
根据另外的实施例，这样设计联接装置并且这样在相邻的活动轮之间布置联接装置，使得通过桥接两个不同步的活动轮实现至少两个额外的换档级。有利地，在这种情况下，通过至少一个摆动操作装置操作相邻的活动轮之间的联接装置，该摆动操作装置在相邻的活动轮之间沿径向向外突出。优选地，与相邻的活动轮的旋转轴线平行地或同轴地布置摆动操作装置的摆动轴线。因此，能够以简单的方式和方法实现至少一个转向挡位(Wendegang)或跨接挡位(Brückengang)。通过跨接挡位能够借助作为驱动装置的变速器输入轴来实现两个另外的挡位或换档级。
混合动力变速器的另外的优选实施例的特征在于，电机通过一个或多个离合器在混合动力驱动系中被布置在另外的驱动发动机和传动齿轮平面之间。另外的驱动发动机优选是上述的主驱动装置，主驱动装置例如被设计为也被称为内燃机的热力发动机。也就是说，电机被布置在另外的驱动发动机，特别是内燃机与实际的变速器之间。由此，电机以简单的方式和方法节省空间地被集成在混合动力变速器中。
混合动力变速器的另外的优选实施例的特征在于，与另外的驱动发动机同轴地布置电机。因此，将另外的驱动发动机的从动轴(例如内燃机的曲轴)与电机的转子及混合动力变速器的变速器输入轴同轴地布置。
混合动力变速器的另外的优选实施例的特征在于，离合器的操作装置优选全部被布置在离合器的一侧上，特别是在离合器的背离另外的驱动发动机的一侧上。操作装置优选地是中央离合器操作装置，也被称为英语术语Concentric Slave Cylinder CSC(对中式分离副缸)。中央离合器操作装置能够特别有利地径向嵌套，以优化地利用轴向的结构空间。
混合动力变速器的另外的优选实施例的特征在于至少一个减振的离合器盘和/或用于隔离振动的摆。如果振动隔离通过减振的离合器盘完成，那么必要时能够省去另外需要的用于消除振动的双质量飞轮。根据电机的尺寸和功率，还能够主动地利用电机，以实现减少或消除混合动力变速器的振动。备选地或附加地，为隔离振动，能够将摆装配在电机的转子上。根据电机的设计方案，转子的惯性矩还能够用于补偿在运行时产生的不希望的扭转不均匀性。
混合动力变速器的另外的优选实施例的特征在于，电机占据混合动力变速器的轴向空间的大约一半。有利地，混合动力变速器的轴向空间的另一半容纳具有在不同的传动齿轮平面中布置的固定轮和活动轮的实际的变速器。
混合动力变速器的另外的优选实施例的特征在于，混合动力变速器的最后的从动齿轮的齿部基本被布置在两个差速器轴承的轴向外侧。最后的从动齿轮也称为英文术语Final Drive。差速器在混合动力驱动系中与基本平行于混合动力变速器的变速器输入轴和变速器输出轴布置的从动轴相配属。
必要时，本发明还涉及一种具有上述混合动力变速器的混合动力驱动系。
必要时，本发明还涉及一种用于在上述混合动力变速器中换档和/或联接的方法。在这种情况下，根据本发明的一个方面，用于在混合动力变速器中换挡和/或同步挡位的操作力绕一个变速器输入轴或多个变速器输轴的旋转轴线以摆动或旋转方式施加。

双离合器8；68的分离合器9，10；69，70在径向内侧分别与变速器输入轴11，12；71，72连接。变速器输入轴11；71作为内侧轴被抗扭地布置在被设计为中空轴的外变速器输入轴12；72中。
另外，附加的离合器13；73也被布置在电机4；64的转子54；84的径向内侧并且与其沿轴向重叠地布置。混合动力变速器1；61还包括与两个变速器输入轴11，12；71，72平行布置的变速器输出轴15；75。
具有两个分离合器9，10；69，70的双离合器8；68被连接在电机4；64的转子54；84与双离合变速器5；65的两个变速器输入轴11，12；71，72之间。附加的分离离合器13；73被连接在主驱动装置(即热力发动机2；62)与电机4；64的转子54；84之间。
在混合动力变速器5；65中，两个固定轮21，22抗扭地与内变速器输入轴11；71连接。两个固定轮23，24抗扭地与外变速器输入轴12；72连接。固定轮21至24与活动轮31至34啮合，活动轮31至34被抗扭地布置或支承在变速器输出轴15上。
固定轮21和活动轮31被布置在第一齿轮平面中。固定轮22和活动轮32被布置在第二齿轮平面中。固定轮23和活动轮33被布置在第三齿轮平面中。固定轮24和活动轮34被布置在第四齿轮平面中。布置在四个齿轮平面中的固定轮21至24和活动轮31至34用于表示四个挡位，该挡位也被称为换挡级。
除了能够通过固定轮21至24和活动轮31至34直接构成的挡位或换档级之外，能够通过桥接相邻的活动轮32，33构成两个另外的的挡位或换档级。
最后的从动齿轮40被布置在双离合变速器或混合动力变速器5；65的从动侧。最后的从动齿轮40也被称为最终传动部件。
为了附加挡位中的一个，必须将相应的活动轮31至34与变速器输出轴15；75连接。该连接通过联接装置或同步器41至43实现。在这种情况下，活动轮31至34与变速器输出轴15；75之间的抗扭连接经由仅简略示出形状配合式联接装置实现。
该形状配合式联接装置例如分别包括联接体，该联接体与连杆通过滑动套筒共同作用。连杆与行星齿轮装置的行星架连接。触发操作联接装置或同步器41至43通过行星齿轮装置完成。行星齿轮装置沿轴向被布置只在两个相邻的活动轮31，32和33，34之间。在这种情况下，有利地，行星齿轮装置特别节省空间地、部分地被布置在活动轮的运行齿部的径向内侧。
为了操作联接装置或同步器41，42，操作件或操作装置45，46摆动或旋转。例如，通过操作装置45，46的摆动或旋转来加速或制动行星齿轮装置的行星架。这导致产生相对于各活动轮的相对速度。通过该相对速度或相对运动，操作同步并接合挡位。
在混合动力变速器5；65的输出侧布置具有差速器轴承51，52；81，82的差速器50。最后的从动齿轮或最终传动部件40沿轴向被布置在差速器轴承51，52；81，82的外侧。
通过联接装置或同步器(也被称为转动式换挡机构)41至43的旋转或摆动操作，混合动力变速器5；65的变速器长度能够减少约百分之三十到百分之六十。在这种情况下，有利地，较短的旋转操作与换挡齿轮装置一起使用。
有利地，换挡齿轮32，33和与其相邻的转动式换挡机构41，42的连接能够在这种情况下作为第三换挡位置。其优点在于，能够仅通过两个执行器操作整个变速器。备选地，能够为转动式联接装置43使用单独的执行器。
与内燃机或热力发动机2；62的发动机轴线同轴地布置具有转子54；84的电机4；64。电机4；64被布置在内燃机2；62以及具有固定轮21至24和活动轮31至34的实际的传动装置之间。电机4；64能够通过附加的分离合器13；73与内燃机2；62分离。电机4；64的转子54；84与双离合器8；68的输入轴连接。
优选地，用于离合器8，9，10，13；68，69，70，73的操作装置55；85被布置在一侧上。优选地，离合器8，9，10，13；68，69，70，73的操作由也被称为CSC的中央操作系统完成，其中，大写字母CSC代表英文术语Concentric Slave Cylinder(对中式分离副缸)。
在具有较大的电机4；64的方案中，能够有利地省去图1中所示的双质量飞轮3。如图2中通过圆形符号91，92简略示出，减振器能够通过减振盘，特别是离合器盘实现。此外，电机4；64能够用于实现主动减振。
此外，有利地，如果电机4；64的惯性矩足够补偿在运行时产生的扭转不均匀性，则能够省略附加的减振器。备选地或附加地，如图2中通过矩形符号93简略示出，用于隔振的摆能够装配在电机64的转子84上。
