    • A differential gear mechanism includes a differential case, a first side gear, a second side gear, a first pinion and a second pinion. The first side gear is rotatably mounted within the differential case and has a first outer diameter. The second side gear is rotatably mounted within the differential case and has a second diameter. The first pinion gear is meshed for rotation with the first side gear during a first meshing event. The second pinion gear is meshed for rotation with the second side gear during a second meshing event. The first and second pinion gears form a torque transfer arrangement configured for transferring torque between the first and second pinion gears and the first and second side gears to rotate the first and second side gears. The first and second outer diameters are distinct such that the first and second meshing events are offset in time.
    • 差动齿轮机构包括差速器壳体,第一侧齿轮,第二侧齿轮,第一小齿轮和第二小齿轮。 第一侧齿轮可旋转地安装在差速器壳体内并且具有第一外径。 第二侧齿轮可旋转地安装在差速器壳体内并具有第二直径。 在第一啮合事件期间,第一小齿轮啮合以与第一侧齿轮一起转动。 在第二啮合事件期间,第二小齿轮啮合以与第二侧齿轮一起转动。 第一和第二小齿轮形成扭矩传递装置,其配置用于在第一和第二小齿轮与第一和第二侧齿轮之间传递扭矩,以使第一和第二侧齿轮转动。 第一和第二外径是不同的,使得第一和第二啮合事件在时间上偏移。

    • An inter-axle differential assembly (10) comprises an input shaft (14), an output shaft (30) arranged coaxially with respect to each other, a differential gearing and a dedicated reversible lubrication pump (50) disposed between the input and output shafts. The reversible gerotor type lubrication pump (50) includes a rotor (52) driven by the input shaft (14), and an impeller (52), both disposed within a pump body (56) coupled to a side gear drivingly connected to the output shaft (30). Thus, the lubrication pump (50) generates lubricant flow only during the differential action between the input shaft and the output shaft, i.e., when needed. An oil flow generated by the lubrication pump (50) is supplied to various components of the inter-axle differential gearing through a gallery of fluid passages.
    • 轴间差速器组件(10)包括输入轴(14),相对于彼此同轴布置的输出轴(30),差速齿轮传动装置和设置在输入轴和输出轴之间的专用可逆润滑泵 。 可逆式转脚型润滑泵(50)包括由输入轴(14)驱动的转子(52)和叶轮(52),两者都设置在泵主体(56)内,泵主体(56)联接到驱动地连接到输出端 轴(30)。 因此,润滑泵(50)仅在输入轴和输出轴之间的差动作用(即,在需要时)产生润滑剂流动。 由润滑泵(50)产生的油流通过流体通道的通道供给到车轴间差动齿轮的各种部件。
