Abstract: The present disclosure provides a differential gear to be mounted on a vehicle, including a pair of side gears, at least two pinion gears meshed with the side gears, and a differential case that houses the side gears and the at least two pinion gears. Lubricating oil is supplied to and discharged from the inside of the differential case via an opening portion. The differential case includes at least two seat surfaces formed on the inner peripheral surface of the differential case so as to support the pinion gears, weir portions provided between the adjacent seat surfaces and extending in a direction along the rotational direction of the differential case to connect between the adjacent seat surfaces, and an oil reservoir portion formed on the inner peripheral surface by the weir portions so as to be positioned on the opposite side, in the axial direction of the side gears, of the opening portion from the weir portions. Consequently, it is possible to render the differential gear compact by suppressing a shortage of lubricating oil for a sliding portion well.

Abstract: In a transfer, a high thrust can be given to a front-wheel driving clutch by a high magnification function of a screw mechanism. Further, a necessary stroke for an operation of a high-low switching mechanism can be obtained by the screw mechanism. Accordingly, with the use of one motor, the screw mechanism, and a transmission mechanism, it is possible to perform a switching operation of the high-low switching mechanism and a torque adjustment of the front-wheel driving clutch by the same system. Hereby, it is possible to perform, with accuracy, the switching operation of the high-low switching mechanism and the torque adjustment of the front-wheel driving clutch, based on a motor rotation angle Am of one motor.

Abstract: A torque transfer assembly for a tandem axle drive train, having a first synchronizer assembly including a first portion arranged to non-rotatably connect to a power input shaft arranged to receive torque from an engine, a second synchronizer assembly, an overdrive gear assembly engageable with the first synchronizer assembly, and an inter-axle differential gear (IAD) arranged to engage first and second power shafts, and engaged with the second synchronizer assembly. In a differential mode, a first torque path is formed from the power input shaft to a first axle through the first synchronizer, the power shafts, the IAD and second synchronizer, and a second torque path is formed from the power input shaft to a second axle through the first synchronizer, the power shafts, and the IAD, and, in overdrive mode, a third torque path is formed from the power input shaft to the first axle through the first synchronizer.
