A road implement having an auxiliary shaft associated with an auxiliary engine, a coupling and/or uncoupling device and a method for controlling the coupling and/or uncoupling between a shaft of road implements and an auxiliary engine associated with the shaft. Specifically, the road implement has a device that couples and/or decouples the effects of at least one auxiliary engine to a shaft, allowing that, in a coupled state, the shaft receives auxiliary traction from the auxiliary engine or the auxiliary engine acts as a generator of braking energy in a regenerative way and, in a decoupled state, it allows the shaft to rotate freely so that no energy losses occur due to friction of the device components.

A vehicle axle assembly including an axle housing, carrier assembly, and first and second axle shafts. The axle housing is formed from an upper beam and a lower beam that are positioned in a clam-shell arrangement. The carrier assembly includes a carrier housing and a differential that includes a ring gear arranged in meshing engagement with a pinion. The first and second axle shafts extend outwardly from the differential in opposite directions. The pinion is rotatably supported by a self-lubricating cartridge pinion input bearing and the outboard ends of the first and second axle shafts are rotatably supported by self-lubricating and unitized grease wheel end bearings. These bearings do not require lubrication from oil contained inside the axle housing allowing for a reduced oil fill level in the axle housing, creating less viscous losses and better efficiency.

An electric drive axle for a motor vehicle including an axle housing, an electric motor having an output shaft directly driven by a bevel pinion gear coupled thereto, a fixed ratio planetary gear arrangement, a differential unit including a differential gear arrangement housed within a differential case and a first clutch selectively operable to connect a portion of the planetary gear set to a stationary member of the drive axle so that the drive axle operates in a first gear ratio.

An assembly of a first component designed as an axle or a shaft on a second component, is provided, in particular for a vehicle. The first component is secured to the second component at least in the axial direction of the first component. At least one of the components has at least one first deformation on one side, the deformation being used to secure the first component on the second component in a first direction which coincides with the axial direction. At least one of the components has at least one second deformation on the same side, the second deformation being used to secure the first component on the second component in a second direction which coincides with the axial direction and is opposite the first direction.

In a pressing step, a first forged product is pressed by a first die, and thereby, a second forged product including a rough flange having a thickness-changing portion is produced. The thickness-changing portion includes a front part protruding frontward from a side of a rough web part and a rear part protruding rearward from the side of the rough web part. Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die, whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion is formed.

An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly includes a mounting plate mountable to the suspension of an off road vehicle, and a portal box is mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in a first position in which the output shaft is positioned to extend the wheelbase relative to the input shaft, or in a second position in which the output shaft is positioned in vertical alignment with the input shaft.

An axle assembly having a drop gear set and a countershaft transmission. The drop gear set may operatively connect a rotor of an electric motor to a countershaft. The countershaft transmission may operatively connect the countershaft to a drive pinion. The electric motor and the countershaft transmission may be positioned on opposite sides of a differential assembly.

An axle cooling system for a vehicle that has a first axle hydraulic circuit that passes through a first axle assembly, a second axle hydraulic circuit that passes through a second axle assembly, a first pump that circulates axle oil through the first axle hydraulic circuit, a second pump that circulates axle oil through the second axle hydraulic circuit, a first temperature sensor that monitors a first axle temperature of the first axle assembly, and a second temperature sensor that monitors a second axle temperature of the second axle assembly. The first pump and the second pump are independently controlled from one another to circulate axle oil through the corresponding first or second axle hydraulic circuit.
