摘要： A power transfer unit assembly for a vehicle. The power transfer unit includes a housing, an internal variable speed differential positioned within the housing, a first front side shaft rotatively connected to the differential, a second front side shaft rotatively connected to the differential, an input shaft interconnected to at least one of the first and second side shafts, and at least one shifting mechanism for engaging at least one of the first and second shafts with at least one mode selection gear set. Engagement of the mode selection gear set transfers torque through the input shaft to selectively engage with a second gear set interconnected to a power transfer final drive unit assembly having an internal variable speed differential.

摘要： A variable speed front differential assembly for a vehicle is provided including a first side shaft, a second side shaft, and an input shaft. An offset differential case houses a differential mechanism engaging the first side shaft and the second side shaft. A speed selection assembly is movable from a first speed position to a second speed position. A speed reduction assembly is mounted adjacent the offset differential case. The speed selection assembly directly engages the offset differential case housing when in the first speed position such that a 1:1 drive ratio is achieved. The speed selection assembly engages the offset differential case through the speed reduction assembly when in the second speed position such that an increased drive ratio is achieved.

摘要： The application aims at determining the locked or unlocked state of a differential (10). According to a first aspect, the determination is carried out on basis of a speed difference of output shafts (16, 18) using speed sensors (36, 38). Steering angle may be used as further input. In a second aspect, a sensing system (70) senses actuating pressure, voltage or current of an actuating mechanism (44). In a third aspect, the first and second aspects can be combined.
