摘要： The splines of a connection between a connecting collar and transmission input shaft includes a main lubrication oil passage extending axially through an input gear in alignment with a blind bore provided in a wall of a compartment containing the input gear and a second gear meshed with the input gear and partially immersed in an oil reservoir defined by a lower region of the compartment. An oil capture recess is located in a wall region above the blind bore and adjacent a roller bearing supporting one side of the input gear. A bypass lubrication oil passage connects the capture recess to the blind bore. An oil transfer tube is carried by a sheet metal cup mounted in a circular recess joining the blind bore and has opposite ends positioned in the main lubrication oil passage and the blind bore. The bypass passage bypasses the roller bearing.

摘要： A final drive transmission includes concentric inner and outer metal face seals at an interface between fixed and rotating housing sections for preventing oil contaminating material from entering the housing. Each face seal includes identical metal face seal rings that are biased into sealing engagement with each by identical frusto-conical elastomeric rings. The metal rings are generally L-shaped in cross section, with the metal rings of the outer face seals being constructed to withstand extreme conditions by making their cross section approximately twice that of the inner metal rings. Together with interface surfaces, the assembled inner and outer face seals define a sealed cavity which contains lubrication oil. A reservoir of oil with an oil level sensor is coupled to the sealed cavity and in this way it is determined whether or not oil is leaking from the cavity so that steps may be taken to avoid a catastrophic failure.
摘要翻译：最终驱动变速器包括在固定和旋转的壳体部分之间的界面处的同心的内部和外部金属表面密封件，用于防止油污染物质进入壳体。每个表面密封件包括相同的金属表面密封环，其通过相同的截头圆锥形弹性体环偏压成与每个表面密封接合。金属环的横截面通常为L形，外表面密封件的金属环通过使它们的横截面约为内金属环的横截面的两倍而被构造成经受极端条件。与接口表面一起，组装的内表面和外表面密封件限定了包含润滑油的密封腔。具有油位传感器的油储存器联接到密封腔，以这种方式确定油是否从空腔泄漏，以便可以采取步骤以避免灾难性故障。
