Abstract
A drive system for transport of a passenger transport installation including an escalator or a moving walkway. Steps or pallets of the transport are actively connected to pulling elements which can be moved in the transport direction by at least one electric motor provided with a gear train having a chain wheel. The electric motor containing the gear train is positioned in one of the reversing areas of the transport and a further electric motor exclusively serves for the linear motion of the transport. Bushes/rolls of plate link chains are adjacent to or roll along individual teeth of the chain wheel while only getting into line contact, outside the tooth ground of the chain wheel. A point of force application of the bushes/rolls on the respective tooth of the chain wheel is realized such that only a one-directional force application component is generated at the respective tooth.
