摘要： Wheel assembly (200) a self-propelling trolley (100), comprising a wheel (111,112); an electric motor (151,152) arranged to perform a rocking drive pattern; an electric connector (220), arranged to connect the motor (151,152) to a battery (156); and a mechanical brake (230) activatable so that a rotational movement of the wheel (111,112) is limited, The invention is characterised in that the mechanical brake (230) is arranged so that, in an engaged state, the wheel (111,112) can turn freely in relation to the trolley (100) across a ground distance of between 5 and 20 cm between a first rotary limit position and a second rotary limit position. The movement limitation is provided by several elongated concentric tracks interacting with a pin.

摘要： System (100) for loading and unloading an article (10) into and out from the trunk (21) of a car (20). The invention is characterised in that the system (100) comprises a movable platform (110), arranged to be supported by the said trunk (21) and to horizon-tally move the article (10) supported by said platform (110) between a first position com-pletely inside the trunk (21) and a second position completely outside of the trunk (21); a lifting device (120), arranged to be supported by a trunk cover (22) of said car (20), and to move the article (10) between said second position and a third position on the ground; and a trunk cover support device (130), arranged to be mounted in the car (20) and to therein support the said trunk cover (22) in an open position when the article (10) is lifted by said lifting device (120).

摘要： Self-propelling trolley assembly(100), comprising a battery (156); at least one wheel (111,112) which is driven by an electric motor (151,152;1), which electric motor is powered by said battery; a rotation position or velocity sensor (9) arranged to sense a rotation position or rotation velocity of at least one trolley wheel (111,112); a user interface (153); and a control unit (150) arranged to regulate the electric motor based upon input from said user interface so as to affect a rotation of said wheel according to particular drive patterns. The invention is characterised in that the control unit is arranged to implement at least a feedback assisted propulsion drive pattern, based upon information read from said position or velocity sensor; a free-wheeling drive pattern; and a rocking drive pattern, in that all of said drive patterns are implemented using different drive voltage patterns to said electric motor, and in that the electric motor is of a type in which the stator (2) comprises a number of stator (2) poles (7) which is not an integer multiple of a corresponding number of rotor (3) poles and in which the stator poles are subdivided into at least three magnetically and electrically identical subsets (8) that are mounted one after the other around the angular direction of the electric motor.
