System for sliding plug door for a vehicle

摘要

Sliding door system has chain drive (14) which exhibits a transmission (40) arranged at the carriage (3). The transmission is arranged in such a manner that during the outgoing motion of the carriage motion slows down with high torque and at the end of the outgoing motion the lateral motion of the door leaf (26a) increases faster with a low torque. The carriage exhibits an extending arm (41) with a pressure roller (42) for the belt, which is parallel to the outgoing movement of the carriage. A first and second guide roller (45,46) for the belt drive is provided on both side of the arm.
