Abstract
A bottom flange running gear of a monorail has load-bearing running wheels on both sides of a preferably I-shaped running rail. Such a running gear has front and rear lateral guide rollers mounted on preferably vertical axles and in contact with the running rail. A preferably unilateral or one-sided load may be applied to the running gear, preferably by a traction motor. The invention proposes that at least one supporting roller carrier, preferably on the sidepiece of the running gear opposite the traction motor, can be linked coaxially to the axle of one of the guide rollers. The invention further proposes that a supplemental guide roller can be in contact, preferably under the force of a laterally positioned spring on the running rail, against the edge of the bottom flange of the running rail. Additionally, a supporting roller, mounted on a preferably horizontal supporting roller axle, may be in contact, from below, against the bottom flange of the running rail.
