Abstract: Methods and devices to physically stabilize a unit load of stapled unit loads such as at least two standard containers applied atop each other and on top of at least one Automatically Controlled Vehicle (AGV), during transport of the load in all directions on the ground. The AGV arranged below the unit load has at least one wheel-bogie having at least one wheel at each corner, the bogie being controllably pivotable at its geometrical center to a frame of the AGV with each wheel being controllably pivotable at its respective fixation points. During transport in a longitudinal direction of the total unit, each bogie is translated to a diagonal position in relation to its position of introduction as the wheels simultaneously are controlled so as to maintain their rolling direction in the direction of transport, so as to enhance the traction of the AGV.

Abstract: An electric drive system including an electric motor arranged to rotate a drive shaft. A differential includes a first planetary gear being drivingly connected to a first output assembly. A second planetary gear configuration is in driving engagement with the first planetary gear configuration via an output shaft. The second planetary configuration is drivingly connected to a second output assembly. The motor is disposed between the first and second planetary gear configuration. The first planetary gear configuration is arranged to co-act with the second planetary gear configuration so as to provide a differential function. The ring gears of the first and second planetary gear configurations are engaged via a reversing assembly for the differential function. Also, a motor driven unit, such as a motor vehicle.
