The door actuated by a direct linear motor for public transport means is designed as a sliding door, while a mechanism guide holder /2/ is attached to the vehicle body over the door opening, with a holder /10/ and a linear motor /4/, and a movably attached actuator /3/, on which the door wing /1/ is suspended, a rotor of the linear motor /4/ is a part of the actuator /3/, while at least two end sensors /7/ detecting the end position of the door, at least two stops /5/ fixing the door in the open and closed positions and a cable guiding rod /9/ are arranged on the holder /2/, while at least two tongues /6/ are arranged on the actuator /3/ of the sliding door.

The door actuated by a direct linear motor for public transport means is designed as a push-out sliding door, a mechanism frame /3/ is attached to the vehicle body over the door opening, a holder /4/ is attached by means of at least two balance beams /5,6/, an electric linear motor /8/ and a movably attached carriage /7/ are arranged on the holder, the carriage is guided by a pulley /10/ in shape of the guiding rail against the frame /3/, while a linear motor rotor /8/ is a part of the carriage /7/, and the door wing /1/ is placed by its arm /2/ by means of a traveller /9/ on the holder /4/, and the carriage /7/ is connected by gearing via the traveller /9/ with the door wing /1/.

Improvements to vehicle-transporting railway cars comprising movable bridge plate supports which avoid interference with door clearance requirements, and improved end door lock, and a flexible deflector for decreasing air flow about the outer edges of the end doors. The movable bridge plate supports comprise a lower deck bridge plate support which is movable between a retractable position in which it can support the free end of the bridge plate connected to an adjacent car, and an extended position in which it may be pivotally connected to a bridge plate while spanning a door track. An upper deck bridge plate is provided which comprises a movable member and fixed member, with the movable member and fixed member in combination engaging opposite sides of one of a bridge plate for pivotal connection thereto. Each of the lower deck bridge plates includes a support member for engaging the free end of a bridge plate connected to an adjacent car, and includes a foot to support provided by the door track when in extended position. The improved lock includes lubrication conduits extending between external surfaces and lock pin apertures in top and bottom walls which are joined by a channel shaped side wall structure, and further includes circumferentional channels within the interior surfaces of the lock pin apertures to, dispose between pin engaging surfaces therein, for distribution of lubricant. The flexible deflector extends inward from each of the side walls where the outer edges of the end doors to decrease or inhibit air flow around the outer edges without contacting the end doors when in closed position. The bridge plate supports, lock, and deflectors all must be sufficiently strong and durable to withstand loads imposed during railway service over extended periods of years, without failure.

The invention relates to a system allowing the actuation and translational movement of sliding doors, wherein, for each door leaf, the system comprises a moving frame (1) which is fixed to a leaf support (10) that can be fixed to the door leaf, where said moving frame (1) can move a given release distance in a direction perpendicular to the plane formed by the door leaf, in collaboration with a release guide (2), and where said moving frame (1) can move in a combined manner in a direction parallel to the door leaf, in collaboration with an opening guide (3), defining two end door leaf-closing and -opening positions, said moving frame (1) being actuated by a drive assembly (11, 12), where said moving frame (1) is attached to a supporting element (19) which is attached to a rolling assembly (20) which, in any position, is kept in contact with an inverted T-section (9) the configuration of which defines the path of the leaf between whichever of the closing and opening positions, the system comprising a guide element (17) comprising a casing (18) that is associated with the supporting element (19) such that, in any position, said guide element (17) and said supporting element (19) are kept in contact with the possibility of moving in relation to one another in a direction substantially perpendicular to the leaf, where said casing (18) of the guide element (17) receives the movement thereof from the drive assembly (11, 12).
