Claim:
A driving system of a self-driving cableway car, the driving system comprising: driving chains disposed on both sides of a vertical plane in which a bearing cable is located, each of the driving chains comprising a plurality of chain links and revolving about chain sprocket wheels having horizontal rotational axes, each of the chain links including first and second link plates connected by chain bolts; a plurality of clamping units carried by the chain links, respectively, each of the clamping units including a roller rotatably supported in the clamping unit, and a friction lining for contacting the bearing cable, wherein each of the clamping units is supported in the first and second link plates of the respective chain link and is displaceable relative to the first and second link plates by penetrating window cut outs in the first and second link plates of the chain link; and lead rails disposed on opposite sides of the bearing cable, each of the lead rails having running faces for the rollers of the clamping units; and a spring device preloading the lead rails, wherein the clamping units, during the revolution of the driving chains, are guided through interspaces formed between the bearing cable and the lead rails, and the friction linings of the clamping units are pressed onto the bearing cable by the rollers rolling out on the running faces of the lead rails which are preloaded by the spring device against the clamping units located in the interspaces between the lead rail and the bearing cable.
