Abstract: A drive for a wheel-driven vehicle, includes a planetary gear system which includes a sun gear, a ring gear, a planet carrier, and planet gears carried by the planet carrier and meshing with the sun gear and the ring gear. The drive includes an electric motor for driving the sun gear and a wheel which is non-rotatably connected to the ring gear. The drive further includes an electromechanical brake for braking the sun gear and/or a drive shaft of the electric motor. The sun gear is arranged between the brake and the electric motor and/or the brake is being accommodated by an axial cut-out of the planetary gear system.

Abstract: A linear encoder has a stationary part and a moving part, and measures and encodes a relative displacement between the stationary part and the moving part along a linear extent of displacement. The encoder comprises multiple machine sensible elements arranged on one of the parts in a predetermined, pattern; and multiple evenly placed sensors arranged along the other part along the entire linear extent, thereby to measure and encode the displacement. The encoder may be an absolute encoder and may be based on magnetic or optical or any other kind of sensing.
