A source of torque has a wheel pair consisting of two wheels which are installed each by its support-rolling surface of wheel on surface of support. The wheels are fit to common axle with possibility of loading each wheel of wheel pair with pressing forces normal to the surface of support. Disc of each wheel is arranged with tracks on which there are installed as one, or as two, rollers. Each wheel is installed to the surface of support with inclination in such way that central part of the wheel end placed at side of adjoining wheel of wheel pair is placed lower than central section of the wheel end that is at side opposite to neighboring wheel of the wheel pair. The arrangement of sections of tracks on the wheels for rollers in places of installation of those forms seat-like surface with stable placement of rollers there at installation of those with possibility to load rollers with pressing forces normal to the support surface. |
