| 摘要 |
An elevator system includes a car or platform to transport passengers and/or goods as well as a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is a sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material and a second layer with a connection plane formed between the first and second layers. At least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—is embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer. A manufacturing procedure for one of the suspension elements is provided. |

1. A sheathed and/or belt suspension element for an elevator system, comprising:
a first layer of the suspension element made of a first plasticizable and/or elastomeric material and having a first exterior surface; a second layer of the suspension element, said first and second layers each being formed of one of polyurethane (PU), polyamide (PA), polyethylene terephthalat (PET), polypropylene (PP), polybutylene terephthalat (PBT), polyethylene (PE), polychloroprene (PCP), polyethersulphone (PES), polyphenylsulfide (PPS), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), and ethylene propylene diene monomer rubber (EPDM) materials; a connection plane formed between the first and second layers; and at least one tension member embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer, wherein said tension member is formed as a rope, a fabric, or a plurality of sub-elements. |
