Description

贯通式驱动桥的轴间差速器润滑结构和车辆
技术领域
本发明涉及贯通式驱动桥的轴间差速器的润滑, 具体地, 涉及一种贯 通式驱动桥的轴间差速器润滑结构和具有该润滑结构的车辆。 背景技术
如图 1所示, 贯通式驱动桥的轴间差速器 4通常安装在由第一壳体 1 和第二壳体 2 (通常统称为过桥箱壳体)形成的第一腔室 A中, 第二壳体 2 和主减速器壳 3形成第二腔室 B。 其中, 贯通轴 5穿过所述第一腔室 A和 所述第二腔室 B, 轴间差速器 4安装在贯通轴 5上并位于所述第一腔室 A 内。 主动齿轮 6安装在所述贯通轴 5上, 主动齿轮 6和从动齿轮 7啮合并 设置在第二腔室 B内。通过设置在第一壳体 1上的加油口 13可以对第一腔 室 A添加润滑油, 以润滑轴间差速器 4。 轴间差速器 4工作时, 能够带动 润滑油飞溅, 从而润滑设置在第一壳体的端部的轴承 10。
由于轴间差速器 4、贯通轴 5和主动齿轮 6相互之间存在装配间隙, 因 而第一腔室 A和第二腔室 B通过该装配间隙连通。第一腔室 A内的润滑油 可能通过该装配间隙流入第二腔室 B而造成润滑油损失。 为此, 通常在第 一腔室 A和第二腔室 B之间设置油道和泵 (例如安装在第二壳体 2上并通 过齿轮轴 7a驱动的齿轮泵 7b),用于从第二腔室 B对第一腔室 A补充润滑 油。
但是, 设置油道和泵使得轴间差速器 4的布置结构需要作出相应调整, 使得结构复杂。 另外, 如果泵出现故障而无法对第一腔室 A补充润滑油, 则轴间差速器 4因第一腔室 A内的润滑油不足而无法得到良好润滑, 也无 法润滑轴承 10, 最终将导致零件烧灼等严重后果。 发明内容
本发明所要解决的问题是贯通式驱动桥轴间差速器的润滑。
为了实现上述目的, 本发明提供一种贯通式驱动桥的轴间差速器润滑 结构, 该润滑结构包括第一壳体、 第二壳体、 主减速器壳和轴间差速器, 所述第二壳体设置在所述第一壳体和所述主减速器壳之间, 并分别与所述 第一壳体和所述主减速器壳形成第一腔室和第二腔室, 所述轴间差速器位 于所述第一腔室内, 其中, 所述第一腔室和所述第二腔室通过连通管连通, 该连通管与所述第一腔室连通的位置比所述连通管与所述第二腔室连通的 位置低。
优选地, 所述第一腔室的下部和所述第二腔室的下部通过第一油封密 封。
优选地, 在第二腔内设置相互啮合的主动齿轮和从动齿轮, 所述第一 油封设置在所述从动齿轮的台肩上。
优选地, 所述第一壳体的远离所述第二腔室的侧设置有第一通孔, 所 述第二壳体的靠近第一腔室的侧设置有第二通孔, 所述连通管的两端分别 插入所述第一通孔和所述第二通孔。
优选地, 所述第一壳体的远离所述第二腔室的端部设置有轴承和轴承 盖, 在所述轴承与所述第一壳体和所述轴承盖之间设置有与所述第一通孔 连通的连通空间。
优选地, 所述轴承盖的端部设置有第二油封。
优选地, 所述第一壳体上设置有加油口。
本发明还提供一种车辆, 其中, 该车辆包括本发明的贯通式驱动桥的 轴间差速器润滑结构。
通过上述技术方案, 当第一腔室内的润滑油通过轴间差速器、 贯通轴 和主动齿轮之间的装配间隙流动到第二腔室中造成第一腔室的润滑油损失 时, 第二腔室中的润滑油可以通过连通管流入第一腔室以弥补上述损失, 确保轴间差速器能够得到润滑。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说 明。 附图说明

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。 在本发明中, 在未作相反说明的情况下, 使用的方位词如 "上、 下、 左、 右"通常是指参考附图所示的上、 下、 左、 右; "内、 外"是指相对于 各部件本身的轮廓的内、 夕卜。
根据本发明的一个方面, 提供一种贯通式驱动桥的轴间差速器润滑结 构, 该润滑结构包括第一壳体 1、 第二壳体 2、 主减速器壳 3和轴间差速器 4, 所述第二壳体 2设置在所述第一壳体 1和所述主减速器壳 3之间, 并分 别与所述第一壳体 1和所述主减速器壳 3形成第一腔室 A和第二腔室 B, 所述轴间差速器 4位于所述第一腔室 A内, 其特征在于, 所述第一腔室 A 和所述第二腔室 B通过连通管 8连通, 该连通管 8与所述第一腔室 A连通 的位置比所述连通管 8与所述第二腔室 B连通的位置低。
在轴间差速器 4的工作过程中, 当第一腔室 A内的润滑油通过装配间 隙从第一腔室 A流动到第二腔室 B中而造成第一腔室 A的润滑油损失时, 第二腔室 B中的润滑油 (用于润滑主动齿轮 6和从动齿轮 7) 可以通过连 通管 8流入第一腔室 A以弥补上述损失, 确保轴间差速器能够得到润滑。
应该理解的是, 除了装配间隙, 第一腔室 A和第二腔室 B只能通过连 通管 8连通, 而不能够通过其他方式连通。为此, 优选地, 所述第一腔室 A 的下部和所述第二腔室 B的下部通过第一油封 9密封。
另外,第一油封 9可以通过适当的方式安装,只要能够避免第一腔室 A 和第二腔室 B之间的除装配间隙和连通管 8以外的间隙即可。 优选地, 如 图 2所示,在第二腔内设置相互啮合的主动齿轮 6和从动齿轮 7, 所述第一 油封 9设置在所述从动齿轮 7的台肩上。其中,轴间差速器 4和主动齿轮 6 分别安装在贯通轴 5上,主动齿轮 6和从动齿轮 7的运转将搅动第二腔室 B 中的润滑油并使第二腔室 B中的润滑油能够通过连通管 8流入第一腔室 A, 以使第一腔室 A中的润滑油保持在所需的液面。
其中, 连通管 8可以由各种适当材料制成。 优选地, 连通管 8可以由 刚性材料制成, 例如可以是钢管或其他金属或合金制成的管, 从而能够提 供刚性的密封连接。 此外, 如图 2所示, 连通管 8可以形成为具有倾斜部 分, 以使连通管 8与第一腔室 A连通的位置比连通管 8与第二腔室 B连通 的位置低。
另外,连通管 8可以设置在任意适当的位置,只要能够连通第一腔室 A 和第二腔室 B即可。 优选地, 所述第一壳体 1的远离所述第二腔室 B的侧 设置有第一通孔 la, 所述第二壳体 2的靠近第一腔室 A的侧设置有第二通 孔 2a, 所述连通管 8的两端分别插入所述第一通孔 la和所述第二通孔 2a。
更优选地, 所述第一壳体 1的远离所述第二腔室 B的端部设置有轴承 10和轴承盖 11, 在所述轴承 10与所述第一壳体 1和所述轴承盖 11之间设 置有与所述第一通孔 la连通的连通空间。 因此, 通过设置所述连通空间, 从第二腔室 B通过连通管 8流入第一腔室 A的润滑油不仅可以提供到轴间 差速器 4, 还可以通过连通空间提供到轴承 10。 换言之, 通过连通管 8流 入第一腔室 A的润滑油中, 一部分用于润滑轴间差速器 4, 另一部分能够 流入连通空间并润滑轴承 10。
具体地, 如图 2所示, 在与第一通孔 la邻接的位置, 第一壳体 1和轴 承 10的外圈之间形成有第一间隙 lb,在轴承 10和轴承盖 11之间形成有与 第一间隙 lb连通的第二间隙 11a (例如第二间隙 11a形成在轴承 10的端部 和轴承盖 11之间以及轴承 10的外圈和轴承盖 11之间)。 第一间隙 lb和第 二间隙 11a共同形成连通空间, 通过连通管 8流入第一腔室 A的润滑油可 以相继通过第一间隙 lb和第二间隙 lla,从而经轴承 10的外圈和端部流动 到内圈, 以润滑轴承 10的滚子。
优选地, 所述轴承盖 11的端部可以设置有第二油封 12, 以避免润滑油 从第一腔室 A外泄。
可以理解的, 第一油封 9和第二油封 12可以具有相同或不同的结构, 只要能够起到密封作用即可。 本领域技术人员可以根据设计需要选用各种 适当结构、 材料的油封零件作为第一油封 9和第二油封 12, 在此不做详细 说明。
此外, 可以在所述第一壳体 1上设置有加油口 13, 以在需要时为第一 腔室 A更换或添加润滑油。加油口 13可以设置在任意适当的位置, 在图示 的优选实施方式中, 由于本发明省略了泵等部件, 因而可以将加油口 13设 置在第一壳体 1的下部。
根据本发明的另一方面, 提供一种车辆, 其中, 该车辆包括本发明的 贯通式驱动桥的轴间差速器润滑结构。 使用时, 通过本发明的贯通式驱动 桥的轴间差速器润滑结构可以确保轴间差速器得到良好的润滑, 以使车辆 平稳运行。
以上结合附图详细描述了本发明的优选实施方式, 但是, 本发明并不 限于上述实施方式中的具体细节, 在本发明的技术构思范围内, 可以对本 发明的技术方案进行多种简单变型, 这些简单变型均属于本发明的保护范 围。
另外需要说明的是, 在上述具体实施方式中所描述的各个具体技术特 征, 在不矛盾的情况下, 可以通过任何合适的方式进行组合。 为了避免不 必要的重复, 本发明对各种可能的组合方式不再另行说明。
此外, 本发明的各种不同的实施方式之间也可以进行任意组合, 只要 其不违背本发明的思想, 其同样应当视为本发明所公开的内容。
