A layshaft disposed parallel with the first axle shaft may comprise a first layshaft gear coupled therewith and meshed with the second driven gear. A second layshaft gear disposed on the layshaft may be in meshed engagement with a first drive gear coupled with the differential apparatus case.

Abstract: A modular electric axle head assembly for a vehicle. An axle assembly of the vehicle includes a banjo portion with a first opening extending from an inner surface to an outer surface of an inboard side of the banjo portion. At least a portion of a differential assembly disposed within at the banjo portion of the axle assembly and is drivingly connected to at least a portion of a gear assembly. The gear assembly is also drivingly connected to a motor output shaft. At least a portion of the gear assembly is disposed within a hollow portion of a gear assembly housing. An outboard portion of the gear assembly housing has a mounting flange that is integrally connected to the inboard side of the banjo portion. A first and second protruding portion extends from the axle assembly mounting flange and provides rotational support for the differential assembly.

Abstract: A drive unit having motor output shaft that is connected to a sun gear is connected to one or more planetary gears that are connected to a planetary gear housing. The housing is connected to planetary gear assembly pinion gear, which is connected to a ring gear.

Abstract: Devices and methods are provided herein for the transmission of power in motor vehicles. Power can be transmitted in a smoother and more efficient manner by splitting torque into two or more torque paths. A continuously variable transmission is provided with a ball variator assembly, a planetary gear set coupled thereto and an arrangement of rotatable shafts with multiple gears and clutches that extend the ratio range of the variator. In some embodiments, clutches are coupled to the gear sets to enable synchronous shifting of gear modes. In some embodiments, clutches are coupled to chain drives to enable synchronous shifting of gear modes.
