Abstract
The present invention pertains to a driven loose wheel axle with individually mounted wheels for single-axle or double-axle chassis for rail-borne vehicles, especially for chassis or bogies on low-platform vehicles, wherein a drive is fastened to the chassis frame on the outside on each longitudinal side of the chassis and the drive is connected to the corresponding loose wheel via a cardanic double coupling. According to the present invention, a wheel-carrying frame (1) with contact surfaces (14) for the primary spring system surrounds the two wheels (2) from the outside; the driven interface (3) of the cardanic double coupling is arranged on the inner side of the wheel and the drive interface of the cardanic double coupling is arranged outside the wheel-carrying frame. The cardan shaft (5) provides a connection between the drive interface and the driven interface (3) and is led through a central opening of the wheel (2) and of the wheel-carrying frame (1).
