Abstract: A final drive for a road vehicle comprises a pinion gear (10) on a pinion axle (4) journaled in a housing (11), the pinion gear being in gear engagement with a crown gear (12) journaled for rotation transversely to the pinion axle (4). The final drive is combined with an all wheel drive (AWD) coupling, comprising a disc package (2) axially controlled by a hydraulic piston (5) for optionally transmitting torque from an ingoing axle (3) to the pinion axle (4) as well as a disc drum (2A) or similar means for rotatably connecting the disc package (2) to the pinion axle. The ingoing axle (3) of the AWD coupling is radially journaled only by the pinion axle (4) in the final drive.

Abstract: A hydraulic pump assembly comprises a rotatable piston drum (20) with at least one centrifugal lever (23) pivotally attached thereto for radial movements between radial flanges (20?) under the action of centrifugal force at rotation of the piston drum. The centrifugal lever (23) is arranged to control the position of a valve member, preferably a ball (22), at the opening end of a bore (21) in the piston drum (20). There is a defined friction surface (28; 32) between the lever (23) and one of the radial flanges (20?), and there are spring means (29-31; 25, 33) for resiliently biasing the lever against said one of the flanges.

Abstract: An electrical axle for a four wheeled road vehicle is provided. The electrical axle comprises an electrical propulsion motor (110) arranged coaxially on said axle (100), a differential mechanism (120) being connected to said electrical propulsion motor for driving two wheels arranged on a first side (160) and a second side (162) of said electrical axle (100), and an electrical torque vectoring motor (132) arranged coaxially on said axle (100) and connected to said fist side (160) and second side (162) for providing a change in torque distribution between said first side (160) and said second side (162) of said axle (100), wherein the diameter of the torque vectoring motor (132) is less than the diameter of the electrical propulsion motor (110).

Abstract: An electric drive axle arrangement for a road vehicle comprises an electric drive motor (1), a differential mechanism (3, 4) for allowing different velocities of drive wheels driven by the drive motor, and a torque vectoring system (2, 6, 7) for controlling the distribution of drive torque between the two drive wheels. A torque vectoring motor (2) of the torque vectoring system is of the non-permanent magnet motor type.
