<p>A drive unit (1') capable of being coupled to a wheeled body (10, 14) to form a vehicle. The drive unit consists of a construction comprising a frame (2) with two opposite edges parallel to the forward direction. Said frame (2) supports a driving power source (6) and is in turn supported along said opposite edges by a pair of side walls (3a', 3b') that are themselves respectively supported on at least one wheel-like member (4b) and define a housing for transmission means connecting the driving power source (6) to the wheel-like members. Each of the side walls (3a', 3b') has two opposite surfaces (7a, 7b) perpendicular to the forward direction, and coupling/uncoupling means (8b, 8b') are provided on said surfaces for releasably engaging the wheeled body.</p> |
