Abstract: A transfer case (12, 90, 130), which may be used to distribute the torque selectively between the primary and secondary driving wheels (2, 4) of an automotive vehicle (A, B), includes an input element (30, 104, 132) and two output elements (32, 34; 106, 108; 132, 134) located along a common axis (X). It also includes a magnetic particle clutch (38, 102, 138) and a planetary gear set (36, 100, 140) which are both organized by about the same axis. The clutch and planetary set are connected together such that they provide a direct path through which torque is transferred from the input element to one of the output elements without slippage. The arrangement further provides a slip path through which torque is transferred from the input element to the other output element with slippage, and this path has two segments, one through the planetary set and the other through the clutch and planetary set. The clutch path accommodates slippage and the proportion of torque transferred through the slip path depends solely on the electric current conducted through the clutch.

Abstract: 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.
