    摘要： An elevator system roller guide device (26) includes a plurality of rollers (32) that roll along a guide rail (28). Dampers (40) that have a selectively variable stiffness dampen lateral movements between the rollers (32) and roller guide device base (30) as the elevator car assembly (20) moves through a hoistway. In one example, the dampers include a magneto-rheological fluid. A controller (50) selectively controls a magnetic field generated by an electromagnet (52) to selectively control the viscosity of the magneto-rheological fluid and the stiffness of the dampers (40).

    摘要： According to an aspect of the present invention, a door drive mechanism for actuating a door of an elevator car laterally between open and closed positions is provided. The door is mounted on the car for lateral movement relative to the car, and is connected to the car by at least one pivotable arm. The door drive mechanism includes a linear door drive mechanism and at least door drive mount. The door drive mechanism is configured to be mounted on the car. The door drive mount is configured to be attached to the door and is in communication with the linear door drive mechanism. The linear door drive mechanism is operable to selectively drive the door drive mount, the attached door, and the pivot arm between the open position and the closed position.
