Description
技术领域
本发明涉及车辆领域,尤其是涉及配备在汽车上的混合动力传动***。
本发明还涉及配备有这种混合动力***的混合动力车辆。
背景技术
由于车辆附件(转向助力,空调...)数量的日益增多,以及由于众多有关碰撞(正面的,有关行人的...)和减少污染(有关催化剂,防微粒过滤器...)方面的规格标准,使得发动机组在车辆中的安装限制变得越来越严格。
由热力发动机和电动机(电力机)组成的车辆混合动力***的确有利于减少消耗和降低污染气体(二氧化碳气体)的排放。
为了实现一种混合动力***,在发动机箱体中,除了通常靠近于热力发动机的那些部件外,还需要安装至少一个用来提供纯电力驱动模式的电动机。
为了应对这一问题,某些车辆制造者提出了一些基于传动装置部件的混合动力***,所述传动装置可以是无级变速传动装置,并且以英文缩写表示为“IVT”(Infinitely Variable Transmission)。
这些传动装置部件主要包括一个行星轮系和两个电动机。
业已区分出混合动力***的多种结构类型:一种是称之为“串联”的混合动力***;一种是称之为“并联”的混合动力***;以及一种是称之为“串并联”的(或者称之为动力分流的)混合动力***。
上述的最后一种结构使用了一个行星轮系,它通过减速器连接于差速器,因而也连接于车轮。
这种结构可以是一种无级变速传动装置,并且不需要离合器。
尤其是可以通过专利文献WO2005/007440中的描述而了解到这种结构类型。
这种解决方案的缺陷在于,一方面,由于电力动力的分流是其工作中必需的,因而其效率并非总是最优;另一方面,这种结构需要重新考虑全部的制造设备。
另一种方案是在热力发动机和变速器之间***一个电动机,通过离合器来保证连接转换。
这后一种方案的缺陷在于,一方面,它增加了发动机组的长度;另一方面,电动机位于变速器的输入端,这限制了混合动力的性能潜力。
发明内容
本发明的目的在于提出一种能够减小上述这些缺陷的混合动力***。本发明的目的还在于提出一种配备有这种混合动力***的车辆。
本发明尤其在于有益地提出了一种紧凑的结构,其中各构件的布置得到优化,以使其体积与标准动力***的体积相当,而且还优化了车辆发动机罩下方的剩余空间。
这种结构的另一个优点在于不需要开发专门的设备。
直接源于本发明的混合动力***的其它优点列举如下:
电动机能够用于制动期间的能量回收;
电动机还能够用于变速期间,以减缓连接的中断;
电动机可以直接或者通过一个减速器连接于后桥,这能够更好地适应其电气性能;
最后,电动机能够用于精确地获知车轮的速度,并且用来替代ABS速度的检测装置。
本发明提出了一种车辆的混合动力***,包括一个连接于机械组件的热力发动机和至少一个电动机;所述机械组件包括连接至差速器的减速箱,而差速器则通过其各自的传动轴连接于车辆的驱动轮;所述电动机包括定子和转子,并且通过机械组件而与热力发动机相配合,以便为驱动轮提供热力驱动和/或电力驱动。
所述的混合动力***其特征在于,电动机设置在差速器和其中一个驱动轮之间,并且围绕着将差速器与驱动轮相连接的传动轴。
通过这种有益的方式,电动机被设置在通常的剩余空间内,它的安装只需要对热力发动机和机械组件作很小的改动。
根据另一个特征,电动机的转子安装连接在一个围绕着驱动轴的空心轴上,并且该空心轴的相对于差速器的那个端部装配成与差速器机械相连。
根据上面确定的本发明的第一实施例,转子直接地机械连接于差速器。
根据该第一实施例,差速器包括一个配备有键齿的空心轴部件,所述键齿与电动机的空心轴的端部相啮合;该空心轴包括一些与所述空心轴部件的键齿互补的键齿。
根据第二实施例,电动机的转子通过一个设置在电动机和差速器之间的减速装置而与差速器机械相连。
根据第一种变型,减速装置包括设置在电动机的转子和差速器的冠齿轮之间的行星轮系;转子的端部相应于行星轮系的中心齿轮,以及差速器的冠齿轮相应于行星轮系的环齿轮。
根据上面所确定的本发明,接纳着和转动地支撑着传动轴第一端部的差速器输出部分,被转动地保持在转子的内部。
根据第二种变型,减速装置是齿轮减速器。
根据这个变型,齿轮减速器包括尺寸不同的第一齿轮和第二齿轮;第一齿轮和第二齿轮在转动上相连,并且分别与差速器的冠齿轮和一个与转子相固定的齿轮相啮合。
根据一个有益的特征,第一齿轮被设置在一个箱体中,所述箱体固定在包含了差速器的机械组件上;以及第二齿轮被设置在封闭着电动机的壳体中;这两个齿轮通过一个驱动轴在转动上相连。
根据另一个变型,电动机是空心的,并且通过设置一个封闭着转子的内壁而进行密封。
根据上面所确定的本发明,电动机被封闭在一个壳体中,该壳体的与差速器相反的那个端部中包含有用于传动轴第二端的轴承装置。
该轴承装置支撑着热力发动机的反力偶连杆(bielletteanti-couple)。
本发明还涉及配备有前面确定的混合动力***的混合动力车辆。
附图说明
通过结合附图阅读下面对于非限制性实施例的说明,本发明的其它特征和优点将更加清楚地显现,其中:
图1是本发明的混合动力***安装在车辆中的俯视图;
图2示意性表示了本发明的混合动力***的第一实施例;
图3示意性表示了本发明的混合动力***的第二实施例;
图4示意性表示了本发明的混合动力***的第三实施例;
图5示意性表示了本发明的混合动力***第三实施例的第一种变型;以及
图6示意性表示了本发明的混合动力***第三实施例的第二种变型。
所有附图中相同的元件标注以相同的参考标记。
具体实施方式
图1-图4都是表示汽车1的视图;如果认为该车是前驱动车辆的话,那就是前部俯视图,如果认为该车是后驱动车辆的话,那就是后部俯视图。
在本说明书中,设定各个附图表示了车辆的前部。
该组装图示意性地表示了汽车混合动力***的主要部件的安装,也就是:热力发动机2,电动机3,以及由变速器5和差速器6组成的机械组件4;所述差速器包括第一和第二输出部分6G,6D,它们分别通过两个传动轴8G,8D和地面连接件9G,9D而连接于车辆1的驱动轮7G,7D。
为了不至于徒劳地增添附图的负担,图中有意识地省略了变速器通常所配备的齿轮组件。
按照这一安装方案,车辆1电动机组的电动机3位于热力发动机2的下游,并且固定在后者的近旁。
图1中的箭头代表了车辆1的前进移动方向。
根据所示的实施例,电动机3的转动轴线YY’平行于热力发动机2的纵向轴线XX’。这两个轴线XX’,YY’分别经过一些相互平行的平面,它们还可以经过一些相互间形成一个角度的平面。
机械组件4沿着与这两个轴线XX’,YY’相垂直的方向延伸,它位于并且固定在热力发动机2和电动机3的端部;热力发动机2和电动机3两者之一或者两者都通过该机械组件4而分别连接于驱动轮7G,7D。
电动机3包括定子10和转子11,这两个元件是同轴的和空心的,并且都位于一个通常为圆柱形的壳体12的内部。壳体12包括一个沿着电动机的纵向轴线YY’延伸的中央空腔13。定子10固定于壳体12,以及转子11位于定子10的内部并且环绕着空腔13。
转子11连接于空心轴14,空心轴的两个自由端从定子11中伸出,并且分别支撑和转动连接于固定在电动机3的壳体12上的第一和第二轴承15,16。这样空心轴14就界定了空腔13,而电动机3布置在该空腔的周围。
传动轴8D对中安装在空腔13中,它在空腔中转动并且从壳体12的两端伸出。
传动轴8D的第一端通过地面连接件9D连接于驱动轮7G,7D中的一个驱动轮7D,它的第二端连接于差速器6的第一输出部分6D。
差速器6的第一输出部分6D在空腔13中延伸,因而也就是在支承着转子11的空心轴14中延伸。
第三轴承17设置在第一轴承15所在的平面中。该第三轴承被支承在空心轴14的内部,并且用来保证差速器6的第一输出部分6D与传动轴8D的同心。
定子10,转子11,空腔13,轮轴8D是同心的,并且具有与电动机3的纵向轴线YY’相应的公共轴线。
按照图2的实施例,电动机3直接连接于差速器6。
转子11以其一端在转动上机械连接于差速器6的壳体18。
其本身为已知结构的差速器6为车辆1的每个驱动轮7G,7D提供了能够对驱动轮进行驱动的一对减速机构。它通常包括一个冠齿轮19,该冠齿轮通过包含了未示出的齿轮传动系的变速器5而机械连接于热力发动机2的轴(未示出)。冠齿轮19设置在壳体18的外周,壳体18是空心的,并且支撑和收容着一些行星齿轮(未示出),这些行星齿轮围绕着各自的行星齿轮轴(未示出)自由转动地安装,而行星齿轮轴被保持在壳体18中。
当差速器6的冠齿轮19被旋转驱动时,行星齿轮驱动着一些中心齿轮(同样也未示出),这些中心齿轮通常是一些分别连接于和安装在每个传动轴8G,8D端部的圆锥齿轮。
壳体18还配备了与轴线YY’同心地延伸的、并且能够与空心轴11的端部21转动结合的空心轴部件20。一些键齿例如以互补的方式分别设置在空心轴20,21上。键齿可以设置在空心轴20的的内部以及空心轴21的外部,或者与之相反。在图2所示的上述第一种情况下,空心轴21的端部伸入到并且啮合于空心轴部件20的内部。
与之相反的方式,那就是空心轴部件20伸入到并且啮合于空心轴21的端部的内部。
由此形成的元件20,21的结合基本上位于机械组件4的箱体22和电动机3的壳体12之间的界面处。传动轴8D的第二端部通过轴承PR被转动地保持在电动机3的壳体12的端部F处。在本发明的有关电动机3的特殊安装方面,壳体12有益地整合了中间轴承的功能,该中间轴承通常由一个作为热力发动机2的反力偶连杆(biellette anti-couple)和传动轴之间的连接件的相关元件而实现。
这样,按照这种布置,车轮7G,7D或者由热力发动机2或者由电动机3以最佳状态而直接驱动。
图3的实施例与图2实施例之间的区别在于,电动机3与差速器6之间的连接是通过行星减速器23实现的。
减速器23由行星轮系构成,它位于差速器6的冠齿轮19和与电动机3的转子11相连的空心轴14之间。
冠齿轮19支撑着设有键齿的空心轴部件24,它相应于行星轮系23的环齿轮。
如同图2的实施例那样,支撑着转子11的空心轴14在其靠近差速器6的一侧设有键齿25,在该实施例中,这些键齿确定了行星轮系23的中心齿轮。
一些行星齿轮26被设置在环齿轮24和中心齿轮25之间,并且与上述两者相啮合。这些行星齿轮由行星齿轮轴27来支撑,而行星齿轮轴自身则固定在电动机3的壳体12上。
按照图4的实施例,电动机3和差速器6之间的连接是通过齿轮减速器28来实现的。
减速器28是由包含了第一齿轮29和第二齿轮30的齿轮轮系所构成,所述第一齿轮29和第二齿轮30具有不同的尺寸,并且分别位于和转动连接于中间轴31的第一端和第二端。中间轴31在差速器6的冠齿轮19和一个齿轮33之间延伸,所述齿轮33被固定在转子11的空心轴14的靠近差速器6的一端上。第一齿轮29和第二齿轮30分别与差速器6的冠齿轮19以及所述齿轮33相啮合。
由于安装间隙和便于安装的原因,中间轴31由相互之间转动上连接的两段来构成可能是有益的。
该齿轮轮系的目的在于,以一个由这些齿轮29,30的齿数和尺寸之比所确定的减速比来将差速器6的冠齿轮19连接于电动机3的转子11。
在该实施例中,齿轮减速器28被设置在一个箱体32中,该箱体附加和固定在机械组件5的下方并且部分地位于电动机3的壳体12的下方。尺寸较大的齿轮30部分地从箱体32中伸出,以便在电动机3的壳体12中与转子11的齿轮33相啮合。
差速器6的冠齿轮19伸出机械组件5的箱体22,以便在减速器28的箱体32中与尺寸较小的齿轮29相啮合。
差速器6的输出部分6D借助于连接在箱体22上的轴承34而保持在机械组件5的箱体22中,并且转动连接于该箱体。
借助于连接在箱体12上的轴承35,传动轴8D保持在电动机3的箱体12中,并且转动连接于该箱体。
在该实施例中,差速器6的输出部分6D不伸入到电动机3中;电动机3与差速器6的连接通过齿轮减速器28而完成。
在图4的第三实施例的第一种变型中,它被表示在图5中,可以再次看到齿轮减速器28,它仍然由包含了不同尺寸的第一和第二齿轮29,30的齿轮轮系所构成,然而它们以不同的方式来设置,以呈现出两级减速的形式:其中与电动机相关的一级减速位于箱体12中。
在该第一种变型中,第一齿轮29单独地被安放和保持在箱体36中,该箱体附加和固定在机械组件4的下方。齿轮29与轴37相连,轴37以其两个端部转动地固定在与箱体36相连的两个轴承中。两个轴承其中之一,尤其是相对于电动机3的那个轴承是开口的,以便为第一轴37的自由端留出外部通道。该自由端上装有能够接纳外部驱动轴的转动连接件。该连接件例如由花键轴类型的连接件而实现。
还是在这个第一变型中,对于齿轮30,它单独地被安放和保持在电动机3的壳体12中。
这里的电动机3的壳体12具有一个面对着齿轮29的箱体36而延伸的凸出部,用于将安装在轴上的齿轮30封闭起来。对于齿轮29来说也是同样;齿轮30与轴38相连,轴38以其两个端部转动地固定在与电动机3的壳体12相连的两个轴承中。两个轴承其中之一,尤其是相对于箱体36的那个轴承是开口的,以便为轴38的自由端留出外部通道。该自由端上装有能够接纳外部驱动轴的转动连接件。该连接件例如由花键轴类型的连接件而实现。
电动机3向差速器6的运动传递是通过外部驱动轴39而实现的,该驱动轴39插在分别承载着齿轮29,30的两个轴37,38各自的自由端之间。中间轴39的两端适合于与分别承载着齿轮29,30的两个轴37,38各自的自由端相配合。
当然,与驱动轴39的这一实施例相关的各种变型是可以预料的。例如,驱动轴39可以与承载着齿轮29,30的两个轴37,38的其中之一相整合。
这种结构能够赋予电动机3以相对于包含有变速箱5的机械组件4而言的完全的独立性。分别对应于机械组件4和电动机3的箱体36,12,在它们的入口通道/出口通道处,通过一些普通的密封接头而具有各自独立的密封。
另一方面,所提出的这种结构是完全模块化的,电动机3能够适应于现有的发动机组,无需对热力发动机2或机械组件4作较大的改动。
在第三实施例的第二个变型中,它被表示在图6中而且采用了与图5相同的连接形式,其中的电动机3是空心的,并且通过设置一个封闭着转子11的内壁40而进行密封。
因而在轴承处就不再需要密封,一个普通的盖子41就足以封闭着电动机3的壳体12。
本发明当然不仅仅局限于所述的这些实施例,而是包含了权利要求书范围内的各种的变化形式。
