技术领域
本发明涉及一种用于机动车辆、特别是用于电驱动的机动车辆的驱动装置。
背景技术
DE 10 2011 088 668 A1公开一种驱动装置，该驱动装置具有至少一个电驱动机、至少一个第一行星传动机构、换挡离合器和差速器。驱动机的转子轴以抗相对转动的方式与由至少三个联接轴形成的行星传动机构的第一联接轴耦联。第一行星传动机构的第二联接轴能借助换挡离合器的换挡套筒以抗相对旋转的方式抵靠驱动装置的部件。第一行星传动机构的第三联接轴与差速器的累加轴(Summenwelle)作用连接。换挡套筒是能滑动的，其要么与第一行星传动机构的第二联接轴形成形状锁合的接合，要么与差速器的累加轴形成传递转矩的作用连接。
DE 10 2012 011 686 A1揭示一种用于机动车辆的驱动装置，该驱动装置具有电驱动机和传动装置，该传动装置由两个行星级和差速器以及离合器形成。经由离合器，传动机构能够可选地与电驱动机耦联以便传递功率，或者与之脱联以便例如使电驱动机处于“滑行”状态。
DE 11 2014 001 283 T5揭示一种用于机动车辆的驱动装置，该驱动装置具有电驱动机和传动装置，该传动装置由带有两个离合器的能切换的行星传动机构和差动传动机构形成。行星传动机构由两个行星级形成。通过其中一个离合器，行星传动机构相互锁止，使得传动装置以1:1的传动比工作。通过使用第二个离合器，能够降低电驱动机的转速。
发明内容
本发明的目的是进一步改进一种用于机动车辆的驱动装置。
根据本发明的用于机动车辆的驱动装置包括经由驱动轴与传动装置作用连接的电驱动机，其中，传动装置具有至少一个第一和第二行星级以及差动级，其中，第一行星级具有带有多个行星轮的第一行星轮组，其中，第一行星轮组的行星轮以能转动的方式布置在第一行星架上并且与第一太阳轮且与第一齿圈啮合，其中，第二行星级具有带有多个行星轮的第二行星轮组，其中，第二行星轮组的行星轮以能转动的方式布置在第二行星架上并且与第二太阳轮且与第二齿圈啮合，其中，第一行星架以抗相对转动的方式与第二太阳轮连接，其中，驱动轴与第一太阳轮作用连接，其中，第二齿圈还静止地固定在壳体上，并且其中，第二行星架与差动级作用连接，其中，第一和第二行星级之间布置有具有第一和第二能动力换挡的离合器的双离合器装置，其中，第一齿圈能经由第一离合器与第二太阳轮连接，并且其中，第一齿圈能经由第二离合器与第二行星架连接。
术语“作用连接”是指两个传动元件能够直接相互连接，或者两个传动元件之间还存在另外的传动元件，例如，一个或多个轴或齿轮。设置有两个相互啮合或咬合的齿轮，用以将转矩和转速从一个齿轮传递到另一个齿轮。齿轮例如是指行星轮组的太阳轮、齿圈和行星轮。
双离合器装置是指具有两个能动力换挡的离合器的装置。另外，术语“能动力换挡的离合器”是指至少具有断开和闭合状态并且在负载下能在至少两个状态之间切换的装置。在断开状态下，离合器不传递任何转矩。借此，离合器仅在至少部分地闭合状态下才在两个与该离合器作用连接的轴之间传递转矩，其中，这两个轴在闭合状态下以抗相对转动的方式相互连接。必然地，在第一离合器的闭合状态下，第一齿圈和第二太阳轮以抗相对转动的方式相互连接，其中，在第二离合器的闭合状态下，第一齿圈和第二行星架以抗相对转动的方式相互连接。各自的离合器特别是构造为摩擦离合器。更优选地，两个离合器相互同轴布置。特别地，各自的离合器能够由各自的致动器来操纵，用以导入各自的离合器的断开或闭合。致动器能够被设计为以能液压操纵、能机电操纵、能电磁操纵或例如能气动操纵。
本发明的技术教导包括，断开两个离合器实现切断功率。闭合第一离合器并断开第二离合器实现第一传动比，其中，闭合第二离合器并断开第一离合器实现第二传动比。优选地，第一传动比不等于第二传动比。例如，第一传动比大于第二传动比。替选地，第一传动比小于第二传动比。
优选地，电驱动机具有定子和转子，其中，转子以抗相对转动的方式与驱动轴连接。必然地，驱动轴构造为转子轴。更优选地，差动级构造为圆柱齿轮差速器，其中，差动级被设置成使驱动机的驱动功率分配到第一和第二从动轴。特别地，驱动机与差动级同轴布置。优选地，驱动轴与两个从动轴同轴布置。特别地，驱动轴构造为空心轴，其中，两个从动轴中的一个从动轴轴向引导穿过驱动轴。优选地，两个从动轴被布置在共同的驱动轴线上。差动级具有第一和第二行星轮组，其中，差动级的第一行星轮组的行星轮与第一从动轴上的齿部啮合，其中，第二行星轮组的行星轮还与第二从动轴上的齿部啮合，并且其中，两个行星轮组的行星轮成对地相互啮合。
附图说明
下面将参照唯一附图结合本发明优选实施例的描述更详细地说明改善本发明的进一步措施。唯一附图示出说明根据本发明的驱动装置的结构的简化示意图。
具体实施方式
参照该唯一附图，根据本发明的用于(图中未示出的)机动车辆的驱动装置具有电驱动机1和传动装置3。驱动机1具有定子13和转子14。驱动机1的驱动功率经由布置在驱动机1与传动装置3之间并构造为转子轴的驱动轴2导入传动装置3中。
传动装置3包括第一和第二行星级4、5以及差动级6。差动级6构造为圆柱齿轮差速器并且设置成使驱动机1的驱动功率分配到第一从动轴15a和第二从动轴15b。驱动轴2与两个从动轴15a、15b同轴布置。另外，驱动机1与差动级6同轴布置。
第一行星级4具有带有多个行星轮7a的第一行星轮组，其中，该第一行星轮组的行星轮7a以能转动的方式布置在第一行星架8a上并且与第一太阳轮9a且与第一齿圈10a啮合。必然地，第一行星轮组的行星轮7a径向咬合在第一太阳轮9a与第一齿圈10a之间。驱动轴2以抗相对转动的方式与第一太阳轮9a连接。
另外，第二行星级5具有带有多个行星轮7b的第二行星轮组，其中，第二行星轮组的行星轮7b以能转动的方式布置在第二行星架8b上并且与第二太阳轮9b且与第二齿圈10b啮合。必然地，第二行星轮组的行星轮7b径向咬合在第二太阳轮9b与第二齿圈10b之间。第二齿圈10b静止地固定在传动装置3的壳体16上。另外，第二行星架8b与差动级6作用连接。
此外，在第一与第二行星级4、5之间布置有具有第一和第二能动力换挡的离合器12a、12b的双离合器装置11。第一齿圈10a能经由第一离合器12a与第二太阳轮9b连接。第二太阳轮9b以抗相对转动的方式与第一行星架8a连接，因此当第一离合器12a闭合时实现了在第一行星架8a、第一齿圈10a与第二太阳轮9b之间的抗相对转动的连接。另外，第一齿圈10a能经由第二离合器12b与第二行星架8b连接。闭合第一离合器12a并断开第二离合器12b实现第一传动比，其中，闭合第二离合器12b并断开第一离合器12a实现第二传动比。第一传动比不等于第二传动比。通过断开两个离合器12a、12b，实现切断功率，其中，驱动机1与两个从动轴15a、15b脱联。
