Der Ausstellmechanismus (13, 14) wird dabei durch ein Hebelsystem und/oder eine Kulissensteuerung gebildet, welches/welche beim Öffnen/Schließen der Schiebetür (2) über einen Totpunkt bewegt wird, bevor/nachdem der Schiebemechanismus (6) betätigt wird/wurde. Darüber hinaus wird ein Schiebetürmodul mit einem solchen Antriebsmodul (1) und einer darin gelagerten Schiebetür (2), ein Schienenfahrzeug mit einem solchen Schiebetürmodul sowie ein Betriebsverfahren für das Antriebsmodul (1) angegeben.
Abstract:
The cylinder (11) actuating the longitudinal guide (5) for sliding the doors (1) actuates said guide with the aid of a C-shaped arm (12) that is integral with the cylinder and hingedly connected to a second arm (14) which is in turn hingedly connected to the guide (5). An articulated rod (16) is hingedly connected to the end of said C-shaped arm (12). Said rod rotates on a shaft (15) to which it conveys a rotational movement during actuation of the cylinder (11). The shaft is in turn designed to transmit said rotational movement generated by the cylinder to the blocking and safety means that keep the doors in embedded or closed position.
Abstract:
Rotary locks used on transit vehicle doors (2) when opened and closed by a rotating helical door drive member (40). In a preferred embodiment, a first lock utilizes a negative thread portion (51) of the helical drive (40). A second lock utilizes a rotating lock pawl (22) and stop (23). The drive (40) and lock can be used to operate door systems with and without separate door hangers. Compensation for camber variations in car structure is provided through the use of spherical mounts or drive member journals (35, 38).
Abstract:
The classical pneumatic cylinder actuating the longitudinal guide (3) ensuring sliding of the doors and by means of which the doors (1) are embedded or disembedded in the body (2) of the wagon, simultaneously actuates a shaft (4), a crank (5) being radially integral with said shaft . The free end of the crank hingedly receives a connecting rod (6) that is in turn hingedly connected to the longitudinal guide (3). When the longitudinal guide (3) is being displaced outward, on which the doors (1) can be displaced in closing or opening direction, the crank (5) and the connecting rod (6) form an approximate angle alpha . Said angle progressively decreases during the embedding maneuver of the guide (3) and, consequently, the doors (1), until a limit situation is reached in which a 0 value of said angle is slightly exceeded and the connecting rod (6) operates as blocking and safety element that keeps the doors in the embedded position thereby preventing improper opening of said doors.
Abstract:
The sliding door is associated with a carriage or support (5) by a telescopic guide, which extends parallel to the door and can be displaced on transversal guides (4) when it is actuated by a pneumatic piston (12) determining two positions of said carriage (5): a retracting position corresponding to the embedding of the door and an outward projecting position in which the door is also projected outward so that it can be displaced longitudinally towards the opening position. A linear motor (14) is mounted on the carriage-support (5) whose output is coupled to the door by means of an appropriate transmission to transmit its longitudinal movement to the door. The door thus describes an angular and straight trajectory, i.e. with an open segment of the door parallel to its own plane and a second segment perpendicular to the first segment and corresponding to the position of embedding.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle roof and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear unit and a track. The electric motor drives a segmented sector inside the track via a gear reduction unit. The segmented sector includes an arcuate link that slides in an arcuate track portion of the track and a plurality of short sector links that are stored in a storage track portion when the liftgate is closed. The arcuate link has an outboard end that is pivotally connected to the liftgate to open and close the liftgate as the arcuate link is extended and retracted by the segmented rack.

Abstract:
A damping device for a hatch in a military vehicle used during its closing and opening, said hatch being integral with hinges hinged with respect to an interface, wherein said device comprises a tubular body integral with the hinges and hinged between two bearings integral with the interface, said body enclosing two fixed damping means between which a rod is positioned, said rod being mobile in translation to activate one of the damping means during the opening of the hatch and the other damping means during the closing of the hatch.
Abstract:
The invention relates to a pivoting sliding door for vehicles, comprising a door wing (3), drive devices (2), transversal guiding devices (4, 5), and longitudinal guiding devices (7), which enable the at least one door wing (3) to move transversal to the vehicle wall and along the vehicle wall. The longitudinal guiding devices move in a transverse direction by means of the transversal guiding devices. When closed, the door is locked by a pivot part (10), which engages inside a guide (12) whereby preventing the door from being unintentionally opened. The invention is characterized in that the pivot part (10) has a guide part (11) that interacts with a guide (12) and that the guide, in the area in which the pivot part (10) interacts with the guide when the door is closed, has a circular arc section (12b) around the actual position of the rotation axis (9) of the pivot part (10).
