ROLLER HAVING A DRIVEN WHEEL, LOAD TRUCK COMPRISING A ROLLER HAVING A DRIVEN WHEEL AND OPERATING DEVICE

摘要

relates to a wheel 31 of the roller 5, including the invention above all the roller axis (6), wherein the wheel is driven by an electric motor, the electric motor, a fixed extension has a circumferential area with respect to the wheel axle (6) and the wheel axle 6, the hub motor 7 for driving the surrounding hub body (7) to a wheel (31) also has a sliding surface (10). To provide the driven roller has an electric motor having the desired structure, according to the present invention, the sliding surface 10 is formed and the sliding surface of the carrier 11 to the sliding surface of the carrier 11 is in the back of the sliding surface 10 a hub body (7) is supported in the same plane. The present invention is also the rollers of one or more than 4 and 5 relates to cargo trucks (1) can be moved manually, including, one of the rollers over the roller 5 has a driven wheel (31). To have an electric motor providing a driven roller having a preferable structure, a configuration is proposed of a roller (5). The invention also relates to an operating device (25), particularly for manually movable cargo truck (1). To provide a driven roller having an electric motor and a preferred structure, in accordance with the present invention, it is formed in the operating device (25) having a substantially annular cross-section having a central through opening. ;
