Description

一种干式差速器的电驱动总成和新能源汽车 技术领域
本发明涉及主减速器总成技术领域，具体涉及一种干式差速器的电驱动总成和新能源汽车。
发明背景
新能源汽车在运行时，为了适应转向和不同路面的工况，两侧车轮经常不等速转动，需要在两侧车轮间设置差速装置，保证驱动轮在各种运动条件下的动力传递，避免轮胎与地面间出现打滑磨损，提高车辆的平顺性。
目前的差速器大部分依靠差速器油封与传动轴外圆密封，差速器花键完全没入油中，没有密封，传动轴装配后定位不精准，偏心量大，导致油封磨损加剧，容易提前失效，产生渗油故障，已不能满足整车的寿命和可靠性要求。
发明内容
鉴于上述问题，提出了本发明以便提供一种解决或者至少部分解决上述技术问题的一种干式差速器的电驱动总成和新能源汽车。
为达到上述目的，本发明的技术方案是这样实现的：
本发明一方面提供一种干式差速器的电驱动总成，所述干式差速器的电驱动总成包括减速器和差速器；
所述减速器包括减速器箱体和减速器端盖；

本发明的干式差速器的电驱动总成，其差速器油封与半轴齿轮外圆相密封，相比传统结构依靠传动轴外圆密封，减小了偏心量与轴向窜动，降低了油封的磨损。
上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，而可依照说明书的内容予以实施，并且为了让本发明的上述和其它目的、特征和优点能够更明显易懂，以下特举本发明的具体实施方式。
附图简要说明
通过阅读下文优选实施方式的详细描述，各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的，而并不认为是对本发明的限制。而且在整个附图中，用相同的参考符号表示相同的部件。在附图中：
图1是本发明一个实施例中的干式差速器的电驱动总成示意图；
图2是图1中的I部局部放大图。
图中各附图标记分别表示：1.减速器盖；2.差速器油封；3.轴承；4.差速器盖；5.半轴齿轮；6.行星齿轮；7.行星齿轮轴；8.半轴齿轮油封；9.差速器箱体；10.减速器箱体。
实施本发明的方式
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。
本发明中所述的“和/或”的含义指的是各自单独存在或两者同时存在的情况均包括在内。
本发明中所述的“内、外”的含义指的是相对于设备本身而言，指向设备内部的方向为内，反之为外。
本发明中所述的“前端、后端”的含义指的本新型使用处于图2的所示的位置，朝右的一端为“前端”，朝左的一端为“后端”。
参见附图1-2，本发明中的变速器包括半轴齿轮5、行星齿轮6、行星齿轮轴7、 差速器盖4、差速器箱体9、减速器盖1、减速器箱体10、轴承3、半轴齿轮油封8、差速器油封2等零件。其中，所述差速器盖4和差速器箱体9固定连接，其相背离的端部设置有轴承安装座，并且它们形成的壳体内部设置有一对半轴齿轮5、一对行星齿轮6、行星齿轮轴7，所述行星齿轮轴7的两端固定在差速器箱体9上，所述行星齿轮6套装在行星齿轮轴7的两端，所述半轴齿轮5和行星齿轮6相啮合。
本发明的创新点在于，本发明还设置有半轴齿轮油封8和差速器油封2，其中，半轴齿轮油封8装配在半轴齿轮5内孔中，密封差速器内腔，隔离润滑油与传动轴。并且减速器壳体1上装配有差速器油封2，油封唇部与半轴齿轮5外圆相配合，起到密封作用，差速器壳体与减速器壳体通过轴承3连接，共同组成一个干式差速器。
另外，在一个实施例中，所述传动轴是通过花键装配在半轴齿轮的内孔中，当然也可以不具体限定所述连接的形式。
由此可知，本发明的公开的电驱动总成，通过半轴齿轮油封的静密封，使得密封结构简单，可靠性高；而差速器油封与半轴齿轮外圆相密封，相比传统结构依靠传动轴外圆密封，减小了偏心量与轴向窜动，降低了油封的磨损。
需要说明的是，本发明中的带上述差速器的电驱动总成是这样工作的：当车直线行驶时，电机带动减速器中的主动齿轮转动，主动齿轮带动被动齿轮转动，被动齿轮通过差速器壳体的旋转带动差速器总成在主减速器箱体内公转，行星齿轮6咬合两侧的半轴齿轮5随差速器总成一起在减速器箱体内公转，两只半轴通过万向节等机构将力及力矩传递给车轮，驱使车轮旋转。
当车转弯时，行星齿轮6产生自转，行星齿轮6将公转的转速及其自传的转速通过半轴齿轮5、半轴以及万向节传递给外侧车轮，使得外侧车轮的转速大于内侧车轮的转速，实现车平顺地转弯。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
