Description

一种机械泵组件及车辆 技术领域
本发明涉及车辆技术领域，特别是涉及一种机械泵组件及车辆。
背景技术
油泵可以作为液压系统的压力源，应用十分广泛，它可以根据驱动形式不同分为电子泵和机械泵。电子泵是依靠单独的小电机驱动的，优点是控制灵活，缺点是价格昂贵；而机械泵是依靠系统本身的动力驱动，不需要小电机，优点是价格便宜，缺点是不能主动控制。
传统汽车的自动变速器中大都会配置价格便宜的机械泵为液压系统提供压力，是因为传统的机械泵由发动机驱动，而发动机只会朝一个方向旋转，所以机械泵只需要朝一个方向泵油，没有双向驱动泵油的功能需求。但纯电动车是依靠电机驱动的，电机会随着车辆前进和倒车来改变旋转方向，传统的机械泵因为只能单方向驱动泵油不能双向驱动泵油，当泵轴旋转方向相反时，泵的吸油口与出油口会自动调换，导致泵产生倒吸问题，无法满足液压系统需求，严重的还会造成吸空，引起泵的气蚀问题。所以在新能源车上采用软件限制倒车性能，或采用昂贵的电子泵，或者采用双机械泵，因此存在成本增加的问题。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的机械泵组件及车辆。
本发明第一方面的一个目的是提供一种能够防止倒吸的机械泵组件。
本发明的另一个目的是要降低电动车的油泵成本。
本发明第二方面的一个目的是要提供一种包括上述机械泵组件的车辆，以在电动车采用机械泵时避免油泵倒吸的问题。
特别地，根据本发明实施例的一方面，提供了一种用于车辆的机械泵组件，所述车辆具有动力总成，所述动力总成包括依次相连的驱动电机、齿轮传动机构和差速器；所述机械泵组件包括：
泵轴，以及设置在所述泵轴上的第一传动轮和第二传动轮；其中
所述第一传动轮和所述第二传动轮配置为分别由设置于所述齿轮传动机构和/或所述差速器的传动轴上的两个目标驱动装置驱动进行转动，且两个所述目标驱动装置、所述第一传动轮和所述第二传动轮中的任意两者通过两个单向轴承分别与其所在的轴相连，使得所述第一传动轮和所述第二传动轮只能单向驱动所述泵轴。
可选地，所述动力总成包括设置于所述齿轮传动机构的传动轴上的任意两个转向相反的目标齿轮作为两个所述目标驱动装置；
所述第一传动轮和所述第二传动轮为分别与两个所述目标齿轮啮合的从动齿轮，且所述第一传动轮和所述第二传动轮分别通过锁止方向相同的两个单向轴承与所述泵轴相连。

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1是根据本发明一个实施例的机械泵组件10的剖面示意图。图2是根据本发明一个实施例的机械泵组件10和动力总成20的结构示意图。如图1所示，一般地，一个典型的机械泵包括泵体1、泵盖9、泵轴6、内转子7和外转子8。泵体1和泵盖9共同限定出密封的腔体且均设有对齐的安装孔，腔体左侧为进油口，腔体右侧为出油口，安装孔用于安装泵轴6，内转子7与泵轴6固定连接，外转子8与内转子7啮合组成转子泵。通过驱动伸出泵体1部分的泵轴6可以使得机械泵进行单向泵油。传统的机械泵的泵轴6上只有一个油泵齿轮，本发明在伸出的泵轴6处设置了两个传动轮。进一步地，本发明提供了一种用于车辆的机械泵组件10，该车辆具有动力总成20，动力总成20包括依次相连的驱动电机21、齿轮传动机构22和差速器23。如图2所示，一个实施例中，本发明的机械泵组件10包括泵轴6以及设置在泵轴6上的第一传动轮3和第二传动轮2。其中，第一传动轮3和第二传动轮2配置为分别由设置于齿轮传动机构22和/或差速器23的传动轴上的两个目标驱动装置驱动进行转动，且两个目标驱动装置、第一传动轮3和第二传动轮2中的任意两者通过两个单向轴承分别与其所在的轴相连，使得第一传动轮3和第二传动轮2只能单向驱动泵轴6。可选地，目标驱动装置可以是齿轮传动机构22原有的齿轮、加设的齿轮、加设的链轮机构或带轮机构等可以带动第一传动轮3和第二传动轮2的装置，在此不做限制。单向轴承特点在于单向锁止功能，它的内圈与外圈可以在一个旋转方向上锁止在一起，在相反的旋转方向上内外圈分离。
本实施例的机械泵组件10通过在泵轴6上设置两个传动轮(第一传动轮3和第二传动轮2)，并通过车辆的齿轮传动机构22和/或差速器23上的部件驱动上述两个传动轮，在合适的位置设置单向轴承。利用齿轮传动机构 22和/或差速器23存在转向不同的轴和齿轮，结合单向轴承的设置，可以有效地控制第一传动轮3和第二传动轮2驱动泵轴6的方向，无论驱动源正转还是反转，均能保证泵轴6只沿一个方向旋转，因此在不改变机械泵内部结构的基础上实现双向驱动泵油，并解决传统机械泵的倒吸问题。因此，本实施例的机械泵特别适用于由驱动电机21驱动油泵的车辆。
进一步地，本实施例在不改变传统的机械泵内部结构的基础上，利用两个传动轮和两个单向轴承去实现泵轴6的单向旋转，这样在成本变化不大的情况下解决了传统机械泵的只能单向驱动泵油问题，相比于电子泵与双机械泵方案，结构更简单，成本更低。
一个实施例中，动力总成20包括设置于齿轮传动机构22的传动轴上的任意两个转向相反的目标齿轮作为两个目标驱动装置。第一传动轮3和第二传动轮2为分别与两个目标齿轮啮合的从动齿轮，且第一传动轮3和第二传动轮2分别通过锁止方向相同的两个单向轴承与泵轴6相连。
进一步的一个实施例中，两个目标驱动装置分别为差速器齿轮231和齿轮传动机构22上与差速器齿轮231转向相反的目标齿轮(具体可为主减齿轮221)。第一传动轮3和第二传动轮2为分别与目标齿轮和差速器齿轮231啮合的从动齿轮，且第一传动轮3和第二传动轮2分别通过锁止方向相同的两个单向轴承(图2中单向轴承一5和单向轴承二4)与泵轴6相连。即第一传动轮3与单向轴承一5的外圈固连，第二传动轮2与单向轴承二4的外圈固连，泵轴6与单向轴承一5和单向轴承二4的内圈均固连，单向轴承一5和单向轴承二4安装方向一致。
图3是根据本发明一个实施例的机械泵组件10在车辆前进时的运行原理图。图4是根据本发明一个实施例的机械泵组件10在车辆倒车时的运行原理图。更进一步的，两个目标驱动装置分别为差速器齿轮231以及与差速器齿轮231啮合的主减齿轮221。单向轴承一5和单向轴承二4都能顺时针向泵轴6传递扭矩、逆时针与泵轴6分离空转(此处的顺时针和逆时针是指图3和图4中的箭头方向)。如图3所示，当车辆前进时，差速器齿轮231与车轮一起顺时针旋转(此处的顺时针是指从车外侧向车侧看)，与差速器齿轮231啮合的主减齿轮221和第二传动轮2都会沿逆时针旋转，与主减齿轮221啮合的第一传动轮3沿顺时针旋转。此时因为单向轴承二4的外圈相对于内圈逆时针旋转而处于分离状态，所以第二传动轮2绕着泵轴6逆时针 空转。此时单向轴承一5的外圈相对于内圈顺时针旋转而处于锁止状态，所以第一传动轮3会带动泵轴6一起顺时针旋转，泵轴6会带动内转子7顺时针旋转泵油。如图4所示，当车辆倒车时，差速器齿轮231与车轮一起逆时针旋转，与差速器齿轮231啮合的主减齿轮221和第二传动轮2都会顺时针旋转，与主减齿轮221啮合的第一传动轮3会逆时针旋转。因为此时单向轴承一5的外圈相对于内圈逆时针旋转而处于分离状态，所以第一传动轮3绕着泵轴6逆时针空转；因为此时单向轴承二4外圈相对于内圈顺时针旋转而处于锁止状态，所以第二传动轮2会带动泵轴6一起顺时针旋转，泵轴6会带动内转子7顺时针旋转泵油。
因此，本实施例的机械泵组件10的第一传动轮3和第二传动轮2在车辆前进或后退时交替工作，保证泵轴6无论在前进还是倒车工况时都能沿一个方向转动，从而实现双向动力源驱动机械泵的功能。
当然，在其他实施例中，上述的第一传动轮3和第二传动轮2还可以是链轮或带轮，两个单向轴承可以均布置在泵轴6上，也可以布置在齿轮传动机构22的传动轴上，只要保证泵轴6单向驱动即可。下文中示出了一些典型的例子。
一个实施例中，机械泵组件还包括分别设置于齿轮传动机构上转向相反的两根传动轴上的第一主动链轮和第二主动链轮作为两个目标驱动装置。第一传动轮3为与第一主动链轮通过第一链条形成链条传动的第一从动链轮，第二传动轮2为与第二主动链轮通过第二链条形成链条传动的第二从动链轮。
进一步的一个实施例中，第一从动链轮和第二从动链轮分别通过锁止方向相同的两个单向轴承与泵轴6相连。
另一个实施例中，第一主动链轮和第二主动链轮分别通过锁止方向相同的两个单向轴承与其所在的传动轴相连。
可选地，第一主动链轮和第二从动链轮分别通过锁止方向相同的单向轴承与第一主动链轮所在的传动轴以及第二从动链轮所在的泵轴相连。
可选地，第二主动链轮和第一从动链轮分别通过锁止方向相同的单向轴承与第二主动链轮所在的传动轴以及第一从动链轮所在的泵轴相连。
以上链轮机构和单向轴承的设置均能满足单向驱动泵轴6的功能，具体原理与前文相似，区别在于，链轮机构的主动链轮和从动链轮的转动方向相同，而相啮合的两个齿轮的转向相反，其他传动过程与前文相似，在此不做 赘述。
另一个实施例中，机械泵组件还包括分别设置于齿轮传动机构22上转向相反的两根传动轴上的第一主动皮带轮和第二主动皮带轮作为两个目标驱动装置。第一传动轮3为与第一主动皮带轮通过第一皮带形成皮带传动的第一从动皮带轮，第二传动轮2为与第二主动皮带轮通过第二皮带形成皮带传动的第二从动皮带轮。
一个实施例中，第一从动皮带轮和第二从动皮带轮分别通过锁止方向相同的两个单向轴承与泵轴6相连。
另一个实施例中，第一主动皮带轮和第二主动皮带轮分别通过锁止方向相同的两个单向轴承与其所在的传动轴相连。
可选地，第一主动皮带轮和第二从动皮带轮分别通过锁止方向相同的单向轴承与第一主动皮带轮所在的传动轴和第二从动皮带轮所在的泵轴相连。
可选地，第二主动皮带轮和第一从动皮带轮分别通过锁止方向相同的单向轴承与第二主动皮带轮所在的传动轴和第一从动皮带轮所在的泵轴相连。
带轮机构的运动原理与链轮机构相似，在此不做赘述。
图5是根据本发明另一个实施例的机械泵组件10的结构示意图。如图5所示，在本发明的一些实施例中，机械泵组件还包括分别设置于齿轮传动机构22的同一根传动轴221上的目标齿轮202和主动皮带轮31作为两个目标驱动装置。第二传动轮2为与目标齿轮202啮合的从动齿轮201，第一传动轮3为与主动皮带轮31通过皮带30形成皮带传动的从动皮带轮301。当然在其他未示出的实施例中，目标齿轮202和主动皮带轮31的上下位置可以互换，从动齿轮201和从动皮带轮301的位置也互换即可。
可选地，如图5所示，从动齿轮201和从动皮带轮301分别通过锁止方向相同的单向轴承二4和单向轴承一5与泵轴6相连。
可选地，从动齿轮301和主动皮带轮31分别通过锁止方向相同的两个单向轴承与从动齿轮所在的泵轴以及主动皮带轮所在的传动轴相连。
本实施例中采用了齿轮和带轮机构的组合来实现泵轴6的单向驱动，由于相啮合的两个齿轮转向相反，而带轮机构的两个皮带轮转向是一致的，因此需要将目标齿轮和带轮机构设置于同一根传动轴才能实现动力源正反转时泵轴6均单向驱动，具体的工作原理可以参见上文，在此不再赘述。
另一个实施例中，机械泵组件10还包括分别设置于齿轮传动机构22的 同一根传动轴上的目标齿轮和主动链轮作为两个目标驱动装置，第一传动轮3为与目标齿轮啮合的从动齿轮，第二传动轮2为与主动链轮通过链条形成链条传动的从动链轮。
可选地，从动齿轮和从动链轮分别通过锁止方向相同的两个单向轴承与泵轴6相连。
可选地，从动齿轮和主动链轮分别通过锁止方向相同的两个单向轴承与从动齿轮所在的泵轴以及主动链轮所在的传动轴相连。
本实施例与图5中的实施例的区别在于将带轮驱动改为了链轮驱动，其他部分相同，带轮驱动和链轮驱动的原理相似，在此不再赘述。
在其他实施例中，第一传动轮3和第二传动轮2还可以通过转向相同的目标驱动装置驱动转动，这时需要将单向轴承设置成锁止方向相反的两个轴承，具体的设置位置可以参考前述的实施例，在此不再详述。
如图2所示，该实施例中使用了大小不同的第一传动轮3和第二传动轮2，并且上下布置，在其他实施例中也可以采用大小相同的传动轮，上下位置可以互换，具体可以根据实际布置空间调整，在此不做限制。两个传动轮的齿数可以根据转速需求进行设置。另外，本发明采用的转子泵，也可以是其它任何旋转形式的泵。
基于同一技术构思，本发明还提供了一种车辆，车辆包括动力总成20和上述任一项的机械泵组件10。动力总成20包括依次相连的驱动电机21、齿轮传动机构22和差速器23。
本实施例的车辆在机械泵的泵轴6上设置两个传动轮(第一传动轮3和第二传动轮2)，并通过车辆的齿轮传动机构22和/或差速器23上的部件驱动上述两个传动轮，在合适的位置设置单向轴承。利用齿轮传动机构22和/或差速器23存在转向不同的轴和齿轮，结合单向轴承的设置，可以有效地控制第一传动轮3和第二传动轮2驱动泵轴6的方向，无论驱动源正转还是反转，均能保证泵轴6只沿一个方向旋转，因此在不改变机械泵内部结构的基础上实现双向驱动泵油，并解决传统机械泵的倒吸问题。
进一步地，本实施例在不改变传统的机械泵内部结构的基础上，利用两个传动轮和两个单向轴承去实现泵轴6的单向旋转，这样在成本变化不大的情况下解决了传统机械泵的只能单向驱动泵油问题，相比于电子泵与双机械泵方案，结构更简单，成本更低。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
