An axle drive for a vehicle comprising at least one drivable vehicle axle comprises a drive shaft that extends along a longitudinal direction of the vehicle, starting from a first side of the axle drive, to a second side of the axle drive and that is configured to receive drive power from an electric motor arranged at the first side and to output said drive power at the second side to a driven shaft that extends at the second side of the axle drive offset from the drive shaft and that is configured to output drive power to the vehicle axle via a bevel gear facing towards the first side. The axle drive further comprises a brake, in particular a parking brake, comprising a brake disk that is arranged at the second side of the axle drive, in a manner facing away from the first side, at the drive shaft or at the driven shaft.

Methods and systems for a locking mechanism in an inter-axle differential are provided. A vehicle system, in one example, includes an electric motor coupled to a clutch assembly in a locking mechanism of an inter-axle differential coupled to a first axle and a second axle, the clutch assembly is configured to selectively disengage the locking mechanism, and in the disengaged configuration the locking mechanism permits speed differentiation between the first and second axles. The system further includes an electric motor brake coupled to the electric motor and configured to selectively apply a brake torque to the electric motor and the electric motor is configured to actuate the clutch assembly.

One vehicle wheel is disconnected from a differential while the vehicle is in a front wheel drive mode. A controller checks for a malfunction of the differential while the vehicle is in the front wheel drive mode and in response to a request to enter an all wheel drive mode. If speeds of the other vehicle wheel and the differential input indicate that the malfunction is present, the all wheel drive mode is disabled and the driver is informed. If fluid temperature indicates a risk of the malfunction, all wheel drive mode is temporarily disabled and the driver is informed. If the temperature condition continues to be present for a predetermined duration, the all wheel drive mode is disabled.

A power transmission assembly for tandem axles of a vehicle, the assembly including an input axle, a first drive axle, a second drive axle, a plurality of engagement/disengagement devices, a locking device, and a differential unit. The differential unit being set for power distribution between the drive axles of the vehicle, from which, in cooperation with the engagement/disengagement devices and the locking device, enables configurations of the drive axles in which the first and the second drive axles are driven, one of the drive axles is driven and the other drive axle is not driven, or all the drive axles are not driven.

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.
