Methods and systems for an electric drive axle of a vehicle are provided. A gear train in an electric drive axle system includes, in one example, an input shaft configured to rotationally couple to an electric motor-generator and including a first gear and an intermediate shaft including a second gear rotationally coupled to the first gear and a third gear and a fourth gear each configured to rotationally couple to a separate gear on an output shaft. In this example, the second gear, the third gear, and the fourth gear have different sizes, the third gear includes an axial extension having at outer surface, and an interior surface of the second gear circumferentially surrounds at least a portion of the outer surface of the axial extension.

In an electric vehicle including a motor shaft connected to a drive motor, a counter shaft coupled with the motor shaft, a drive shaft coupled with the counter shaft, a drive wheel coupled with the drive shaft, a plurality of bearings configured to support the counter shaft, and a plurality of gears configured to rotate integrally with the counter shaft, a torque sensor is disposed in a region in which a slope of a bending moment occurring on the counter shaft is minimum at a time that the drive motor is driven.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

Methods and systems for an electric drive axle of a vehicle are provided. An electric drive axle system includes, in one example a gear train configured to rotationally attach to an electric motor-generator, the gear train includes an output shaft having a clutch arranged thereon and configured to selectively rotationally couple a gear to the output shaft. The gear train further includes a lubrication channel extending between an output shaft and an axle shaft and including an outlet extending through the output shaft and opening into the clutch.

A steering column device includes a metal outer-side cylindrical member, a metal inner-side cylindrical member, and a resin intermediate cylindrical member that is disposed between the outer-side cylindrical member and the inner-side cylindrical member. The intermediate cylindrical member has an oil feed orifice through which the semisolid lubricating oil is guided from an outer circumferential face side to an inner circumferential face side when inserting the intermediate cylindrical member into the outer-side cylindrical member.

A shaft bearing for mounting a shaft of a motor vehicle, having an inner sleeve, an outer body which surrounds the inner sleeve thereby forming a gap, and an elastomer body which connects the inner sleeve and the outer body elastically to one another. The inner sleeve may be embedded in the elastomer body and form a receiving opening for pressing in a bearing element. The inner sleeve may have at least one first deformation which is directed radially inwards in such a way that a shear gap is formed between the first deformation and the bearing element. An elastomer bead that may be formed when the bearing element is pressed in may be compressed within the shear gap.

A vehicle driving apparatus including, a first shaft provided at a center portion of a rotor and having a first bevel gear projected from an top surface of the rotor, a second bevel gear engaged with the first bevel gear and having an inner peripheral surface fitted to an outer peripheral surface of a second shaft extended in a horizontal direction, and a case having a first case forming a first housing space to accommodate the first shaft and the first bevel gear and a second case forming a second housing space to accommodate the second shaft and the second bevel gear. The second case has an opening at an upper surface thereof for inserting the second bevel gear and a cover to close the opening.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.
