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.

A stroller is disclosed. The stroller includes a support frame supported by at least two wheels. The stroller also includes a seat carrier support selectively, removably coupled to the support frame. A swing motor is operatively coupled to the seat carrier support. A seat swing mechanism extends downwardly from the swing motor. The seat swing mechanism has a seat yoke configured to receive and retain an infant seat. The seat swing mechanism is configured to swing the infant seat forwards and backwards when the swing motor is activated.

A carriage rocking system is provided, which is engageable to a front wheel of a carriage to impart a rocking motion thereto during travel. A wheel having a sliding hub is engaged with an axle of the front wheel of the carriage. Translation of a hub assembly to differing positions on a support member of the wheel imparts more or less rocking motion to the carriage.

A rocking device provided with a fastening means (9) for mounting to for example a baby buggy to create an automatic rocking movement of the baby buggy. It comprises a rotating, asymmetrical weight (14) driven by an electric moto (24). The motor and weight are suspended in a rigid fastening bracket. The fastening bracket (13) is fastened to a first side of a vibration dampening connection element (3) of an at least partly soft material. The fastening means is fastened to the other side of the vibration dampening connection element (3), such that the movement of the weight is transmitted through the fastening bracket (13), via the vibration dampening connection element (3) and the fastening device, to the baby buggy. The fastening bracket with motor a weight is enclosed by an outer cover (1, 2) which is not in contact with the fastening bracket, motor or weight. The outer cover is fastened to the vibration dampening connection element (3), such that vibrations from the motor and the weight are not transmitted to the outer cover.
