Description

用于将油从储备容器输送至机动车的传动系统的输送装置
技术领域
本发明涉及一种用于将油从储存容器输送至机动车的传动系统的输送装置,其具有能以选择的方式由机械的直接驱动器或由能接通的电驱动器传动的油泵。
背景技术
这样的输送装置特别是应用在具有混合驱动器的机动车中。在这些混合驱动器中用于供给传动系统的油泵直接由传动系统来驱动。在传动系统停机时,其功能应该被保持并且油泵因而保持运行。
从DE10329215A1中已知一种用于传动系统油泵的驱动装置,其中一个唯一的油泵经由综合传动系统以选择的方式电驱动或直接驱动。为此综合传动系统具有两个功率支路,其中一个功率支路能由内燃机驱动,并且另一个功率支路能由电动机驱动。综合传动系统例如设计为行星齿轮传动装置。这种设计的优点在于,只需使用一个唯一的油泵来以选择的方式电驱动或直接驱动该油泵。然而综合传动系统导致了高结构消耗。
发明内容
本发明的目的在于,这样地改进了开通所述类型的输送装置,使其能被特别简单地构造并且成本低廉地制造。
根据本发明由此解决该问题,即油泵具有两个能彼此相对运动的、用于输送油的构件,并且机械的直接驱动器与能彼此相对运动的构件中的一个连接,并且能接通的电驱动器与能彼此相对运动的构件中的另一个连接。
通过这种设计,由油泵的相应的设计自身实现了驱动油泵的各种可能性。因此避免将综合传动系统前接在油泵之前。因此根据本发明的输送装置能特别简单地构造并且成本低廉地制造。此外,例如当关断直接驱动器前,应提前启动电驱动器时,也可以考虑并行运行直接驱动器和电驱动器。当直接驱动器在运行状态时以过小的转速运行时,同样可以通过接通电驱动器来提升油泵的输送功率。
能彼此相对运动的构件例如可以是两个能彼此独立驱动的叶轮,它们三明治状地重叠布置。然而这由于尺寸较大而导致了不必要的结构消耗。根据本发明的有利改进方案,即油泵具有能相对于能转动的转子转动支承的转动部件,转动部件具有用于转子的油供应部件,由此将用于形成能彼此相对运动的构件的结构消耗简单地较少保持住。通过这种设计,油泵的转子与直接驱动器连接,并且油泵的转动部件与能接通的电驱动器连接。相反的连接同样也是可能的。
根据本发明的另一个有利的改进方案,油泵在结构上被设计得特别简单,即转动部件相对于固定的壳体能转动地支承并借助于径向密封件密封,并且输入接口和排出接口布置用于将油泵液力地连接在壳体上。
根据本发明的输送装置设计得特别紧凑,即壳体具有用于油泵的转动部件和转子的以及和电驱动器的电动机的共同的凹部。此外电动机由此被输送的油冷却并且其噪音被减弱。此外由此可以取消用于电驱动器的轴套管的密封件。
根据本发明的另一个有利的改进方案可以简单地避免通过油的化学或物理影响来影响电驱动器,即壳体具有用于油泵的转动部件和转子的第一凹部和用于电驱动器的电动机的第二凹部。
根据本发明的另一个有利的改进方案能简单地设定在油泵运行时通过电驱动器所提供的驱动转矩,即电驱动器具有变速器(Untersetzungsgetriebe)。
例如转动部件可以具有环绕的齿圈,在齿圈处铰接有相应的驱动器。然而这导致尺寸较大并且进而导致油泵的结构消耗增加。根据本发明的另一个有利的改进方案,油泵设计得特别紧凑,即转子固定在轴上,并且转动部件与相对于轴同心布置的空心轴连接。不言而喻的是,以运动上反转的方式,转子也可以布置在空心轴上,并且转动部件布置在轴上。优选地空心轴仅仅在壳体内部被引导,从而避免了对轴套管的密封。
根据本发明的另一个有利的改进方案,油泵由特别少的待装配的构件构成,即转动部件作为布置在壳体的内部的内壳设计具有径向围绕转子的环件和与转子的端侧相对布置的控制板。环件或控制板优选地具有用于转子的油供应部件。
根据本发明的另一个有利的改进方案,有助于简化油泵的结构消耗,即输入口和排出口布置在转动部件上。输入口和排出口因此作为用于转子的油供应部件。
根据本发明的另一个有利的改进方案,能简单地实现油泵轴向地流入或穿流,即输入口和排出口中的至少一个布置在转动部件的控制板上。
根据本发明的另一个有利的改进方案能实现油泵径向地流出,即输入口和排出口中的至少一个布置在转动部件的围绕转子的环件上。
根据本发明的另一个有利的改进方案简单地避免了驱动器彼此相对的影响,即直接驱动器和电驱动器设计为自行制动的。
根据本发明的另一个有利的改进方案,油泵能特别有利地由两个不同的驱动器驱动,即油泵设计作为内啮合齿轮泵、叶片泵或外齿轮泵。对于这些泵原理而言,相应设计的转子和围绕转子的环件这样共同作用,即以特别简单的方式能选择性地驱动该环件和转子用于输送油料。
附图说明
本发明允许大量的实施方式。为了进一步地说明其基本原理,在附图中示出这些实施方式中的多个,并在下面进行说明。附图示出:
图1示意性示出了根据本发明的、具有机动车的邻接构件的输送装置,
图2是图1的具有两个驱动器的输送装置的第一实施方式,
图3是沿着线III-III通过图2的油泵的截面图,
图4是通过油泵的另一个实施方式的截面图,
图5在截面图中示出油泵的另一个实施方式,
图6是输送装置的第二实施方式。
具体实施方式
图1示意性地示出具有示意性示出的机动车12的混合驱动器2的构件的输送装置1。混合驱动器2具有内燃机3和用于与传动系统无关地驱动传动机动车12的电传动单元5,该内燃机经由传动系统4驱动。离合器将内燃机3与传动系统4分离。输送装置1具有用于为传动系统4供应油的油泵7和设计为贮油槽的储存容器8。由油泵7输送的油到达传动系统4并且在那里再次返回到储存容器8中。
传动系统4具有用于驱动油泵7的直接驱动器9。此外具有电动机11的电驱动器10与油泵7连接。油泵7由此以选择的方式经由电驱动器10或经由直接驱动器9驱动。也可以考虑并行运行直接驱动器9和电驱动器10,以便例如使电驱动器10在切断直接驱动器10之前提前高负荷运行。在机动车12的运行模式中接通电传动单元5并关断内燃机3。在这种情况下也关断传动系统4的直接驱动器9。油泵7在机动车12的这种运行模式中经由电驱动器10驱动。
图2示出通过图1的输送装置1的截面图,该输送装置具有油泵7的部分区域、电驱动器10和直接驱动器9。在此能识别出,油泵7具有带有凹部14的固定的壳体13,凹部用于容纳油泵7的和电动机11的能与电驱动器10一起运动的构件。直接驱动器9具有插入凹部14中的轴15。电驱动器10具有一个完全布置在壳体13的凹部14内部的、同心围绕轴15的空心轴16。为此,壳体13具有油泵7的输入接口17和排出接口18。在轴15上固定有油泵7的转子19。在空心轴16上固定有能相对于转子19转动支承的转动部件20。转动部件20具有径向围绕转子19的环件21和与转子19的端侧相对布置的控制板22,23,以及用于转子19的油供应部件24,25。油供应部件24,25设计作为输入口26和排出口27。输入口26和排出口27例如布置在控制板22,23中。对此可替换地,输入口26和排出口27可以在相应设计的油泵7中布置在环件21中,或者分布在环件21和控制板22,23上。径向密封件28,29相对于转动部件20密封了轴15和壳体13。多个轴承30-33能实现能相对于壳体13并相对于轴15旋转地支承空心轴16。直接驱动器9和电驱动器10设计为自行制动的,以使得当关断电驱动器10时转动部件20固定不动,并且当关断直接驱动器9时转子19固定不动。
如果转动直接驱动器9的轴15,那么转子19相对于转动部件20转动。在此,油经由输入接口17和输入口26被吸入,并且经由排出口27输送至排出接口18。如果空心轴16通过电驱动器10而转动,那么仅仅使具有油供应部件24,25的转动部件20相对于转子19转动。因此,油同样经由输入接口17吸入并被输送至在壳体13中的排出接口18。
图3示出了沿着图2中的线III-III的截面图,即油泵7设计为内啮合齿轮泵36。能由直接驱动器9驱动的内转动体34构成转子19,外转动体35在其上滚动。外转动体35同心地布置在由图2中示出的电驱动器10驱动的环件21中。如果环件21通过电驱动器10而转动,那么外转动体35同样在内转动体34上滚动。在这两种情况下,经由在控制板中的一个控制板22中的在图2中示出的输入口26吸入油,并且将油输送至在另一个控制板23中的排出口27。
图4示出了油泵7的另一个实施方式,其与图2中的实施方式的区别主要在于,该油泵7设计为叶片泵37。转子19在此具有能随各个叶片39转动的盘38,各个叶片在转动部件20的非圆形设计的环件21中顺着滑动。如同在前面提及的实施方式那样,环件21与电驱动器10连接,并且转子19与直接驱动器9连接。
图5示出油泵7的另一个实施方式,其与图2中的实施方式的区别主要在于,油泵7设计为外齿轮泵40。转子19具有中心齿轮41,并且其驱动支承在转动部件20的环件21上的齿轮42,43。在设置转子19的齿轮41的转动方向时,两个第一通道44,45相对于环件21顺时针地导向在图2中示出的输入口26,并且两个第二通道46,47导向排出口27。
图6示出了具有油泵7的直接驱动器9和电驱动器10的输送装置1的另一个实施方式。油泵7如同在图3至5所描述的那样构造。输送装置1的这个实施方式与图2中描述的实施方式不同之处是,在第一凹部50中的油泵7和电驱动器10的电动机48与电子控制装置49以及减速传动系统59一起布置在壳体52的第二凹部51中。此外,直接驱动器9确定驱动空心轴53并且电驱动器10驱动轴54。如同在图2中描述的实施方式那样,油泵7的转子19布置在轴上,并且转动部件20布置在空心轴53上。油泵7与在图2中描述的实施方式相反地布置在直接驱动器9和电驱动器10之间。油泵由此非常简单地液力连接。转动部件20如同在根据图2的实施方式中那样具有作为用于转子19的油供应部件57,58的输入口55和排出口56。壳体52具有输入接口60和排出接口61。
输送装置1与混合驱动器2的连接仅仅示例性地理解。输送装置1同样适用于仅仅通过内燃机3驱动的机动车12。
