Abstract
The invention is directed to a friction wheel drive with a driving roller capable of being driven in a rotary manner, which is mounted on a bearing unit so as to be rotatable about an axis of rotation. The bearing unit is displaceably guided transversely to the axis of rotation, and a circumferential surface of the driving roller can be brought into driving engagement with a friction surface. The bearing unit is coupled to a first mechanical forced guidance system, by which the driving roller, responding to a driving force acting in a first direction, can be automatically pressed against the friction surface with a contact pressing force that increases as the driving force increases. The bearing unit is also coupled to a second mechanical forced guidance system, by which the driving roller, responding to a driving force acting in an opposite second direction, can be automatically pressed against the friction surface with a contact pressing force that increases as the driving force increases.
