Description

混合动力车辆
技术领域
[0001] 本发明涉及根据专利权利要求1的前序部分所述的一种混合动力车辆。
背景技术
[0002] 混合动力车辆具有一个混合驱动器,该混合驱动器由一台内燃发动机以及一台电动机器组成。这种混合驱动器的电动机器不仅能作为电动机来运行而且能作为发电机来运行。除该混合驱动器之外,混合动力车辆还包括一个传动装置,它优选被设计为一个自动换档变速器。混合动力车辆在纯内燃发动机动力下进行驱动的过程中,仅混合驱动器的内燃发动机在混合动力车辆的驱动输出端上提供驱动力矩。相比之下,在纯电动机器动力下进行驱动的过程中,仅混合驱动器的电动机器在混合动力车辆的驱动输出端上提供驱动力矩。当混合动力车辆在一种混合驱动模式下运行时,混合驱动器的内燃发动机与电动机器二者各自在混合动力车辆的驱动输出端上提供驱动力矩。此外,从实践中已经知道混合动力车辆应具有至少一个泵单元,尤其是用于对传动装置和/或对多个辅助单元提供液压油的一个液压泵。直到现在,已经对所述类型的多个泵单元指定了一个分立的驱动器,例如,一个分立的电动机,以便由此来确保甚至在混合驱动器的内燃发动机关机时也能够使泵单元运行。然而,一个分立的驱动器对于泵单元是不利的,因为这些分立的驱动器要求相对大的安装空间,并且还会增加混合动力车辆的总重量。
发明内容
[0003] 本发明基于的目的是提供一种混合动力车辆,其中可以省却用于泵单元的分立的驱动器。
[0004] 所述目的是通过如专利权利要求1中所述的一种混合动力车辆来实现的。所述泵单元能够由该混合驱动器的电动机器驱动。
[0005] 如本发明所提出的,如果该混合动力车辆的泵单元是由混合驱动器的电动机器来驱动,则可将用于该泵单元的分立的驱动器省掉。即使在内燃发动机被关机时,该泵单元由此能够通过该混合驱动器的电动机器来驱动。
附图说明
[0006] 由这些从属权利要求以及该说明中将显现本发明的多种改进方案。本发明的多个示例性实施方案将参见附图予以说明,而本发明并不局限于所述示例性实施方案。在附图中:
[0007] 图1示出了用于阐释本发明的一种混合动力车辆的高度示意性图示;并且
[0008] 图2示出了用于阐释本发明的另一种混合动力车辆的高度示意性图示。
具体实施方式
[0009] 图1示出了在一种混合动力车辆的传动系中的多个组件的高度示意性图示,其中,图1示出了一台内燃发动机10以及一个电动机器11,它们一起形成了混合动力车辆的一个混合驱动器12。
[0010] 除了共同形成了混合动力车辆的混合驱动器12的内燃发动机10和电动机器11之外,图1还示出了被设计为自动换档变速器的一个传动装置13。图1的传动装置13是一个所谓的双离合器变速器。
[0011] 混合驱动器12的内燃发动机10以及还有电动机器11均作用于传动装置13上,确切地说,在图1所示的构形中,其中混合驱动器12的内燃发动机10以及电动机器11是彼此并联地安排的并且彼此并联地作用于传动装置13上。内燃发动机10能够通过一个传动装置内部的离合器14与传动装置13联接并且能够与其脱离联接。电动机器11能够通过另一个传动装置内部的离合器15与传动装置13联接并且能够与其脱离联接。
[0012] 该混合动力车辆还包括设计成一个液压泵16的泵单元,其中在图1的构形中,液压泵16是一个传动装置内部的液压泵16。在图1的构形中,能够通过液压泵16来提供用于至少一个传动装置内部组件17的液压油。可替代地或者额外地,多个辅助单元能够通过液压泵16来提供液压油。
[0013] 在本发明的背景下,液压泵16(它在图1的构形中是一个传动装置内部的液压泵)可以由混合驱动器12的电动机器11驱动,从而相应地液压泵16不要求分立的驱动器。
[0014] 在本发明的一个有利的改进方案中,一个离合器18被连接在液压泵16与该混合驱动器的电动机器11之间。当离合器18闭合时,确切地是在另外将离合器15闭合时,混合驱动器12的电动机器11能够驱动液压泵16。相比之下,当离合器18打开时液压泵16与混合驱动器的电动机器11脱离联接,这样使得混合驱动器12的电动机器11于是不驱动液压泵16,确切地讲甚至是在所述离合器15被认为是闭合的时候也是如此。
[0015] 根据图1,液压泵16被指定了一个液压储能器19。当液压储能器19的加注水平是高于一个限定值时,液压泵16不对液压储能器19进行加注。相比之下,如果液压储能器19的加注水平低于一个限定值,则液压储能器19就由液压泵16来加注。为此目的,在图1的构形中采取一种解决方案,其中当液压储能器19的加注水平高于这个对应的限定值时,离合器18被打开,这样使得液压泵16不能被混合驱动器12的电动机器11驱动。相比之下,当液压储能器19的加注水平低于这个相应的限定值时,离合器18被闭合,这样使得液压泵16于是能够被混合驱动器12的电动机器11驱动以便对液压储能器19进行加注。
[0016] 可以使通过液压泵16对液压储能器19进行加注不仅取决于所述液压储能器的加注水平而且还取决于整个系统的效率。因此可以提供的是,液压泵16仅在混合动力车辆的效率通过这种方式得到增加的时候才对液压储能器19进行加注。因此可以提供的是,例如,液压储能器19在混合动力车辆的制动过程中通过液压泵16来加注,以便由此利用制动能量来加注液压储能器19。
[0017] 通过一种控制装置(它未在此示出),连接在混合驱动器12的电动机器11与液压泵16之间的离合器18可以被自动地打开或闭合,确切地说是优选地随着液压储能器的加注水平而变化和/或随着混合动力车辆19的效率而变化。
[0018] 如已经陈述的,液压泵16可以是一个传动装置内部的液压泵或者可替代地是一个传动装置外部的液压泵。液压泵16可以被设计成一个固定排量的泵,这个泵在一个限定的转速下总是提供一个恒定的输送量。可替代地,液压泵16还能够设计成一个可变排量的泵,其输送量在一个限定的转速下是可以调节或改变的。液压泵16能够可替代地或者额外地由内燃发动机11驱动。
[0019] 在图1的构形中,被设计为混合动力车辆空调系统的空调压缩机20的一个泵单元还可以通过混合驱动器12的电动机器11来驱动,其中一个离合器21被连接在混合驱动器12的电动机器11与空调压缩机20之间。当离合器21打开时,空调压缩机20与混合驱动器12的电动机器11脱离联接,于是其中所述空调压缩机不被混合驱动器12的电动机器11驱动。只有在离合器21闭合时空调压缩机20才可以同样被混合驱动器12的电动机器11驱动。空调压缩机20可以独立于液压泵16由混合驱动器12的电动机器11来驱动。
[0020] 图1中所展示的构形仅仅是一个实例,其中混合驱动器12的内燃发动机10和电动机器11并联地作用在被设计为双离合器变速器的一个传动装置13上。
[0021] 与其相对比,如通过图2中的构形示出的,这还有可能使混合驱动器12的电动机器11与内燃发动机10共轴地作用在传动装置13上。在这种情况下,连接在液压泵16与混合驱动器12的电动机器11之间的离合器18的安排被改变并且离合器15被省略。
