Description
本申请是于2009年6月10日递交的申请号200910146034.0的名为“具有滤油器的油底壳”的发明专利的分案申请。
技术领域
本发明涉及用于发动机或变速器的、优选地由塑料或金属制成的油底壳,该油底壳包括:过滤器壳体,该过滤器壳体包括过滤器壳体顶罩、过滤器壳体底罩、过滤介质、过滤器入口和过滤器出口;和油底壳的底板区域中的排油孔,该排油孔通过使用具有外螺纹的排油螺丝能封闭的方式实现,排油螺丝来自油底壳的底侧。
背景技术
现有技术中已知的油底壳,优选地由金属或塑料制成,通常具有置于油底壳底板紧邻处的单独的过滤器,该过滤器包括至少一种滤油器介质和一个滤油器壳体,该过滤器优选地实现为吸油滤油器。具有这种滤油器的这种类型的油底壳是已知的,例如从EP 1 339 954 B1、EP 1 333 160 A1和DE 10 2005025 726 A1中获悉。以上公开的过滤器存在的问题是,由于各部件的分离,特别是例如油底壳与滤油器的分离,因而各部件相互之间的复杂紧固/固定是有必要的。这些部件的连接在现有技术中例如通过铆接进行。而且,单独设置在油底壳中的滤油器在过滤器底侧与油底壳内侧之间具有间隙,这导致不可控的吸气以及由于松动的过滤器在油底壳中的运动产生的噪音。这导致过滤器效率降低和使用舒适度下降。
在其它情况下,过滤器例如通过焊接/胶合被永久紧固到油底壳中,因而不能再移动。这例如从DE 100 08 692 A1和DE 197 35 445 A1中获悉。这些实施例具有的缺点在于不可能单独更换过滤器,因而,更换油底壳/滤油器单元非常复杂和昂贵。
发明内容
因此,本发明的目的在于公开一种具有滤油器的油底壳,其不再具有上述缺点,和/或特别是公开一种优选地由金属或塑料制成、具有滤油器的油底壳,其中,滤油器能够持久集成,同时减少必要部件的数量、组装更容易、降低生产和安装成本、减少不希望出现的不利技术效果,而且过滤器位于油底壳中而使其能够易于根据需要更换并因而是可分离的。
以上目的通过根据本发明一方面的油底壳而实现,其中,过滤器壳体包括内螺纹,该内螺纹被实现以接纳排油螺丝的外螺纹,过滤器壳体至少部分地通过排油螺丝被紧固在油底壳上,该排油螺丝封闭排油孔并使用其外螺纹啮合过滤器壳体侧上的内螺纹。因此,本发明的核心想法在于,使用设置在油底壳中的排油螺丝,不仅用于封闭设置在油底壳底板区域中的排油孔,而且同时通过排油螺丝将过滤器壳体的至少一部分(特别是过滤器壳体底罩和/或过滤器壳体顶罩)紧固到油底壳上。以这种方式,因为排油螺丝已经根据种类被设置为油底壳中的标准装备,因此提供滤油器壳体的至少一部分的特别有效和经济的定位。根据本发明,排油螺丝的已知的封闭功能已经被增加了用于紧固滤油器壳体的至少一部分的紧固功能。可以提供另外的紧固件以紧固过滤器壳体。不过,基本上,本发明的核心想法还允许过滤器壳体仅通过排油螺丝被紧固在油底壳上。
而且,上述目的通过根据本发明另一方面的油底壳而实现,其中,过滤器壳体具有夹紧装置,该过滤器壳体使用夹紧装置通过以下方式被定位和紧固在油底壳中:夹紧装置啮合位于油底壳侧上的制动装置。
过滤器壳体底罩优选地包括内螺纹,该内螺纹被实现以接纳排油螺丝的外螺纹。在此实施例中,除了过滤器壳体底罩以外,过滤器壳体还具有以适合方式连接到过滤器壳体底罩的过滤器壳体顶罩。为此目的,可提供进一步的连接装置,优选地为可移除的连接装置,例如制动装置,以允许更换位于过滤器壳体内的过滤介质。而且在这种情况下,基本上可以例如提供过滤器壳体底罩以及具有适合内螺纹的过滤器壳体顶罩,过滤器壳体底罩和顶罩在安装状态下沿排油螺丝的拧入方向位于彼此之上,使得排油螺丝将过滤器壳体底罩以及过滤器壳体顶罩均紧固在油底壳上。
在进一步的优选实施例中,过滤器壳体底罩由油底壳的底板区域形成,过滤器壳体顶罩包括被实现以接纳排油螺丝外螺纹的内螺纹。在此实施例中,因为这种功能通过油底壳底板的子区域实现,因此单独的过滤器壳体底罩不是必要的。因此,将被紧固在油底壳上的在一侧开放的模块至少包括过滤器壳体顶罩(并可能还包括过滤介质)。相应地,用于接纳排油螺丝的外螺纹所必需的内螺纹位于过滤器壳体顶罩上。为了使排油螺丝的外螺纹更易于啮合过滤器壳体顶罩侧上的内螺纹,内螺纹优选地被实现为从过滤器壳体顶罩的内表面突出并指向朝向油底壳底板的方向。内螺纹和/或形成内螺纹的过滤器壳体顶罩的一部分特别优选地沿油底壳底板的方向突出,而足以使过滤器壳体顶罩的这一部分在安装状态下竖立在油底壳底板上和/或与油底壳底板接触。以这种方式,过滤器壳体顶罩被特别充分地紧固在油底壳上。
此外,已经显示有利的是,根据本发明的用于固定过滤器壳体和/或其部件的排油螺丝的紧固功能与另外的紧固件组合。为此目的,油底壳例如具有制动装置,而且适合的夹紧装置共同位于过滤器壳体底罩上和/或过滤器壳体顶罩上,夹紧装置以啮合油底壳侧上的制动装置的方式实现,以将过滤器壳体底罩和/或过滤器壳体顶罩定位在油底壳中。以这种方式,特别是通过多部件的过滤器壳体,例如可以非常多样地设计各个过滤器壳体部件的紧固能力。这样,例如,过滤器壳体底罩可使用排油螺丝以上述方式紧固,过滤器壳体顶罩可通过诸如保持肋之类的适合的夹紧装置被夹紧在油底壳侧上的诸如制动连结板之类的制动装置中。
在进一步的优选实施例中,过滤器单元包括被实现以接纳过滤介质的容器,特别是容器框架。该容器可为单独的部件,或者也可成形在油底壳中。而且,密封件或粘接层可设置在容器与过滤器壳体顶罩和/或油底壳底板之间,以实现特别紧密的连接。
作为借助排油螺丝将过滤器紧固在油底壳内的可替代方案,诸如保持肋之类的夹紧装置可替代地用于将过滤器定位和紧固在油底壳内,该夹紧装置以啮合位于油底壳侧上的制动装置,例如朝向油底壳内腔突出的连结板的方式实现。因而,在此实施例中,排油螺丝和/或排油孔的位置对于过滤器的紧固并非是决定性的。
排油螺丝以及夹紧装置均可用于将滤油器可移除地固定在油底壳内。每种所述紧固变例,即,第一是通过排油螺丝,或第二是通过夹紧装置,或第三是通过排油螺丝/夹紧装置的组合,既可适用于过滤器壳体的一件式实施例,即,过滤介质由过滤器壳体顶罩接纳,过滤器壳体底罩由油底壳底板区域替代,也可适用于过滤器壳体的两件式实施例,即,过滤介质被夹紧在过滤器壳体顶罩和底罩之间。
附图说明
本发明将在下文中基于图中所示的示例性实施例进行更详细的说明。在示意性附图中:
图1显示通过第一实施例中的具有滤油器的油底壳的透视侧截面图;
图2显示第二实施例中的具有滤油器的油底壳的透视图;
图3显示图2中的油底壳沿线A-A的透视截面图;
图4显示图2或3中的油底壳的侧截面图;和
图5显示第三实施例中的具有滤油器的油底壳的透视俯视图;和
图6显示图5中的油底壳沿线B-B的截面图。
具体实施方式
根据图1的第一实施例的油底壳1包括:滤油器2,该滤油器被紧固在油底壳1上,并具有:过滤器壳体顶罩3、过滤器壳体底罩4、被夹紧在过滤器壳体罩3和4之间的过滤介质5、过滤器出口6、具有密封环8和外螺纹(未示出)的排油螺丝7、以及在过滤器壳体底罩上的内螺纹(未示出),该内螺纹由连接到过滤器壳体底罩的螺纹衬套9形成。围绕排油螺丝7的区域还在图1中以详细放大图进行强调。
在根据图1的示例性实施例中,由紧固在过滤器壳体底罩4上的过滤器壳体顶罩3和过滤器壳体底罩4制成的两件式过滤器壳体因而仅通过位于过滤器壳体底罩4上的螺纹衬套9的内螺纹被紧固,其中排油螺丝7的外螺纹啮合所述内螺纹。因此,为了更换整个过滤器单元,只需移除排油螺丝7。该过程也是特别有利的,因为在实际中换油通常也伴随着更换滤油器。
总之,特别是对于第一示例性实施例形成以下优点:
a)更易于安装在油底壳上(和/或变速器上),
b)持久定位过滤器,
c)可以仅通过移除排油螺丝7来更换过滤器,和
d)将排油螺丝7用作过滤器固定元件,从而不需要其它紧固件。
根据图2、3和4的第二实施例包括油底壳1′、过滤器壳体顶罩3′、过滤介质5′、过滤器出口6、具有密封环8的排油螺丝7、紧固在过滤器壳体顶罩侧上并具有内螺纹(未示出)的螺纹衬套9、过滤器罩密封件10、过滤器入口11、下游区域12和上游区域13。例如被实现为框架状的容器14用于在此过滤器壳体20的一件式实施例中接纳过滤介质5′。
与第一实施例的主要差别在于,过滤器壳体是部分地由油底壳1′的底板区域形成。以这种方式,在此实施例中单独的过滤器壳体底罩是不必要的。不过,为了在此实施例中还实现向外密封的过滤器壳体内腔,油底壳包括在与过滤器壳体顶罩3′的接触区域中的过滤器罩密封件10,该过滤器罩密封件10仅在过滤器入口11的区域内中断。为了允许将过滤器壳体和/或在这种情况下的过滤器壳体顶罩3′紧固在油底壳上,在此实施例中,在过滤器壳体顶罩3′上设置内螺纹,此内螺纹由紧固在过滤器壳体顶罩3′中的螺纹衬套9形成。螺纹衬套9位于从过滤器壳体顶罩3′突出的区域中。此区域从过滤器壳体顶罩3′的内表面突出而足以使该区域在根据图2的安装状态下竖立(stand up)在油底壳1′的底板区域上。
总之,除了第一实施例的优点a)至d)以外,第二实施例还具有以下优点:
e)节省过滤器底罩,
f)可形成更平坦的结构,和
g)在过滤器底侧与油底壳内侧之间无需任何间隙。
本发明的进一步的优点来自根据图5和6的第三示例性实施例。根据此变例,滤油器2在油底壳1上的定位和紧固不是通过排油螺丝7执行,而是通过夹紧装置15执行,无论过滤器壳体20被设置为一件式还是两件式形式,夹紧装置15总是位于过滤器壳体20上,并啮合位于油底壳侧上的诸如制动连结板(detent web)之类的制动装置16。这些紧固件(夹紧装置15和制动装置16)优选地设置在相对两侧上,并因而将滤油器2紧固到油底壳1″内,而与排油螺丝7(未示出)的位置无关。因此,排油孔和/或排油螺丝的实际位置对于滤油器2的紧固并不重要。
对于根据图3的第三示例性实施例,除了前述示例性实施例的优点a)、b)和d)至g)以外,结果形成的优点在于,对于容器紧固而言,能自由选择排油螺丝的位置。为了增强将滤油器2紧固到油底壳1中,可选地,除了夹紧装置15以外,还可以使用排油螺丝7(未示出)来定位和固定滤油器2。
集成的滤油器2优选地用作吸油滤油器的主流(main stream)滤油器。还可以想到的是,将具有另外连接部的滤油器2实现为吸油滤油器和压油滤油器的组合。根据需要,将主流滤油器和副流(secondary stream)滤油器均位于在共用过滤器壳体20中也是有利的。
