摘要： An improved inter-axle differential locking clutch is provided that aligns the actuator and the clutch member thereby reducing space and material requirements in the axle assembly housing. The clutch also eliminates the need for a pushrod and shift fork thereby reducing tooling and production costs, as well as eliminating issues associated with misalignment of the piston and pushrod, relative rotation of the shift fork and clutch member, and tipping of the shift fork. The clutch includes one or more pistons disposed within either the axle housing or a carrier supporting the input shaft bearing. Fluid pressure actuates the pistons against a clutch member causing selective engagement between the clutch member and either a side gear driven by the inter-axle differential or a differential case housing the differential gears of the inter-axle differential.

摘要： An improved lubrication system for drive axle assemblies (10) is provided that uses a collector (24) in connection with a filter plug (26) to lower the dynamic lubricant level in the drive axle assembly (10) and filter contaminants in the lubricant sump (36). The collector (24) is affixed to a cover plate (14) attached to the drive axle housing (12) and defines a well (72) and a flow passage (74) proximate the bottom of the well (72). The flow passage (74) is aligned with an opening (38) through which lubricant is inserted into the housing. A plug (26) with a filter (84) is inserted through the opening (38) in the cover plate (14) and into the flow passage (74). The invention reduces churning losses by lowering the dynamic lubricant level in the axle assembly without having a negative impact on lubricant life.

摘要： A tandem axle assembly is provided. The tandem axle assembly includes a forward axle assembly (12) and a rear axle assembly (14) and an intermediate drive shaft assembly (16) extending between the two axle assemblies. The forward and rear axle assemblies both includes a pinion gear (98) rotating responsive to an inter-axle differential (22) and a ring gear (100) in mesh with the pinion gear. The forward pinion gear is offset from the rear ring gear by a second predetermined distance. The second predetermined distance (H1) is greater than zero, but is less than the first predetermined distance (H2). The variation in offsets enables both equal working angles (21, 22) in the intermediate drive shaft assembly and a reduction in those angles as compared to conventional tandem axle assemblies. Further, the variation in offset results in stronger and quieter gearing.
摘要翻译：提供串联轴组件。串联轴组件包括前轴组件（12）和后轴组件（14）以及在两个轴组件之间延伸的中间驱动轴组件（16）。前轴和后轴组件都包括响应于轴间差速器（22）旋转的小齿轮（98）和与小齿轮啮合的齿圈（100）。前小齿轮从后齿圈偏移第一预定距离（H1），而后小齿轮从后齿圈偏移第二预定距离（H2）。第二预定距离大于零，比特小于第一预定距离。与转换串联轴组件相比，偏移的变化使得中间驱动轴组件中的相等的工作角（21,22）能够减小这些角度。此外，偏移的变化导致更坚固和更安静的传动装置。
