变速器齿轮系挡板
摘要：
本发明涉及变速器齿轮系挡板。一种变速器，包括：变速器壳体；设置在所述变速器壳体内的可旋转部件；和设置在所述可旋转部件下方的贮槽，用于存储液压流体。齿轮系挡板设置在所述可旋转部件和所述变速器壳体之间。所述挡板包括外表面；限定腔的内表面，所述腔大致包围所述可旋转部件；和从所述外表面径向向外设置的多个突片。所述多个突片与所述变速器壳体接触以防止所述挡板旋转。多个开口定位在所述挡板的底部。所述多个开口在所述内表面和所述外表面之间延伸穿过所述挡板。来自于所述可旋转部件的液压流体收集在所述挡板的内表面上且通过所述多个开口被引导出所述腔进入所述贮槽。
摘要（英）：

A transmission includes a transmission case, a rotatable component disposed within the transmission case, and a sump disposed below the rotatable component for storing a hydraulic fluid. A gear train baffle is disposed between the rotatable component and the transmission case. The baffle includes an outer surface, an inner surface defining a cavity that substantially encircles the rotatable component, and a plurality of tabs disposed radially outward from the outer surface. The plurality of tabs are in contact with the transmission case to prevent the baffle from rotating. A plurality of openings are located at a bottom portion of the baffle. The plurality of openings extend through the baffle between the inner surface and the outer surface. The hydraulic fluid from the rotatable component collects on the inner surface of the baffle and is directed out of the cavity through the plurality of openings into the sump.
