Definitions

  • the invention relates to a drive device for entry / exit devices for public transport vehicles.
  • Such entry / exit devices are known in particular for passenger doors, but also for entry ramps, sliding steps and the like on vehicles of public passenger transport. Often these are arranged in the region of the door frame or door portals above a passage opening.
  • sliding doors are described in EP 10 409 79 A2 and EP 13 146 26 Al.
  • the drives shown therein are therefore particularly suitable for sliding sliding doors, which perform a pivoting and a lateral displacement during the opening and closing operation.
  • Drive devices for pure rotary or swing doors, ie doors that do not shift sideways are usually located above or below the doors in the area of the door portal.
  • DE 203 16 764 Ul describes the arrangement of a drive device in the upper region of the door portal. However, the arrangement of the drive over the door is disadvantageous in terms of space and space requirements.
  • a locking by hand is possible, for example, by a folding of appropriate levers, in vehicles of passenger traffic, however, the locking must be done automatically usually.
  • locking devices are used, which effect and control, for example, the folding of a lever or the engagement of snap elements via electric motors. These locking devices are separate from the drive Device for the opening and closing process independently. Before opening a door, this must first be unlocked or the door must be locked accordingly after closing. This can be done by a competent person, such as the train driver, outputs a corresponding signal via an actuating element, but it is also conceivable that locking and unlocking operations automatically initiate closing operations or opening operations.
  • the object of the present invention is to provide a drive device for entry / exit devices for vehicles of public passenger transport, which is as simple as possible, can be arranged to save space and in particular the locking device is robust and resistant.
  • the disadvantages of the prior art should be avoided.
  • the object is achieved by a drive device for entry / exit devices for vehicles of public transport, with a Verrieglungsvorraum for locking / unlocking the entry / exit devices and a drive unit, which
  • the holding member acts as an abutment for a torque of the drive unit
  • An essential idea of the invention is therefore to use the already existing drive device for actuating the locking device. So there are no additional motors or drive means necessary, the drive device is used without significant structural changes directly for the operation of the Verrieglungsvorraum.
  • the only condition is that the generated torque of the drive unit interacts with the locking device in such a way that it initially causes an unlocking during the opening process, for example of a door, and only then does the door move.
  • the generated torque of the drive unit is thus used for two tasks, so to speak, which take place in succession or, depending on the embodiment, in parallel.
  • the decisive factor is that when the door is set in motion, it will be unlocked beforehand. In the opposite case, ie during the closing process, the door is advantageously locked by a snap or rotary latch lock.
  • the torque of the drive unit can be transmitted to the rotary column, for example via an output shaft, whereby this rotates, but initially only the locking device actuated and only then a transmission of torque to the opening / closing devices he follows.
  • the actuating element is then connected to the locking device and the entry / exit device in such a way that said two-stage action can take place.
  • a slot may be provided in which a bolt which is connected to the entry / exit device, is slidably mounted
  • the actuator is also also connected to the locking device, for example via a linkage.
  • the distribution of the use of the torque takes place over that the torque is taken off at a second location on the drive unit.
  • an output shaft of the drive unit is connected to the rotary column, while the actuating element is fastened, for example, to a housing of the drive unit and is fixedly connected to the locking device.
  • the drive unit is mounted in a torque bearing that allows movement of the drive unit within the rotary column, without a torque is transmitted to the rotary column.
  • the slot has a curvature corresponding to the rotational movement.
  • the drive unit When the drive unit is switched on, the drive unit thus first rotates itself and carries along the actuating element, which is articulated on the locking device. The locking device is thus actuated without the torque is transferred to the rotary column Ü. By locked in this state door the rotary column acts as a torque arm. If the rotation of the drive unit is blocked by the end of the slot and the door is unlocked, the torque of the drive is removed at the drive shaft and thereby driven the rotary column.
  • the invention is further based on the basic idea to arrange the drive unit directly in a rotary column, the entry / exit device, that is usually a door moves.
  • the space above the door is no longer needed and can be used for other facilities.
  • an opposing bearing is opposed to the torque applied by the drive device.
  • the drive unit is therefore attached to a fixed component of the vehicle.
  • the output torque of the drive device can be transmitted to the rotary column and this rotates.
  • the placement of the drive unit directly in the rotary column in addition to saving space also has many advantages in terms of maintenance and installation of the entire drive device.
  • the storage according to the invention can advantageously also take into account that, due to the length of the rotary column, twisting and deflections thereof during operation can hardly be avoided.
  • the movements of the rotary column come about by the fact that the vehicle is compressed or torpedoed due to acceleration and braking processes and cornering. In the case of buses, tire contact with curbs or similar edges also causes vehicle deformation and thus movement of the rotating column.
  • the drive unit is fixed to a stationary component, such torsions and deflections of the rotary column can adversely affect the drive device.
  • the drive unit is therefore connected via a bearing with the holding member that allows a tumbling of the rotary column, however, prevents rotation about the rotation axis Z-Z. Tumbling is understood to mean a deflection out of the axis of rotation Z-Z in the X and / or Y direction. This function, so to speak, lifts a relative movement between the drive unit and the column.
  • a guide shaft which connects the drive unit to the bearing, slidably mounted in a guide of the bearing.
  • the guide shaft is preferably non-circular for transmitting the torque, it may for example have a polygonal or polygonal geometry.
  • the rotary column itself is rotatably mounted, preferably also in the same holding member which also supports the drive unit.
  • a conventional pivot bearing for supporting the rotary column, this can rotate in the holding member while compensating for positional deviations between the upper and lower bearings in the X and Y directions.
  • the pivot point of the guide shaft and the rotary column bearing should lie on a plane, so be arranged approximately at the same position of the axis of rotation ZZ. This prevents Tensions and loads on the bearings and causes the movement of the drive unit and rotary column as parallel as possible.
  • the movable and flexible mounting of the drive device or drive unit allows the installation of the drive device in different vehicles. It is even conceivable to use the drive device in a rotary column with low inclination, for example up to 5 ° inclined position. Also, the movable storage helps compensate for installation tolerances, which facilitates the installation and maintenance of the entire drive device.
  • a ball-and-socket joint bearing has proved to be a particularly suitable bearing.
  • the guide shaft is guided by means of balls in a ball socket.
  • spherical recesses are arranged, which hold the balls in position.
  • corresponding elongated recesses in the Z direction are provided, in which the balls are guided. Due to the position of the elongated guides in the Z direction, the rotational movement is prevented by Z, but at the same time allows a tumbling about Z-Z or a combined rotation about X and Y.
  • the ball seat can preferably be constructed in two parts.
  • the guide shaft may preferably have a continuous bore extending along its longitudinal axis, through which the necessary cables and similar connections can be guided.
  • a bore has the advantage that on the one hand the space utilization is optimized, on the other hand guided cables and connections are protected.
  • the drive unit can be constructed and arranged differently.
  • the transmission may be connected via its output shaft as the guide shaft to the bearing, but it is also conceivable an arrangement in which the output shaft of the drive motor is connected as a guide shaft fixed to the bearing.
  • the housing of the transmission for example a planetary gear, is firmly connected to the rotary column.
  • the drive unit is only rotated in contrast to the first embodiment, so that the transmission points in the direction of the ground. If the drive motor is energized, rotates the housing of the drive unit, whereby the rotary column in rotation becomes.
  • an outer tube for the drive unit and the torque support in the area of the bearing can be omitted.
  • a non-self-locking drive unit or a non-self-locking reduction gear can be provided, so the blockade is not provided by the drive unit or the transmission, but by a blocking device.
  • a manual operation of the entry / exit devices is always guaranteed due to the low self-locking in an emergency, it must be repealed to only the blocking effect of the blocking device. This leads to a high degree of security.
  • an additional blockage of the drive is absolutely necessary. This can be done by an additional braking device which causes a mechanical locking of the drive in the non-energized state.
  • This brake can be unlocked manually and manually by hand in order to decouple the drive and thus enable electrical and / or manual operation.
  • the manual unlocking of the brake can be done via a known spring-applied brake with manual release, the manual release of the brake can be used for a mechanical emergency release.
  • Such brakes are known by the term "low-active brake.”
  • any other suitable blocking device can be used, for example, the brake can act on the output shaft of the output motor by means of spring force and be electromagnetically releasable.
  • a so-called high-active brake is possible.
  • Such a brake is also known under the term anchor brake.
  • anchor brake This means that the brake is active when energized and the door is fixed in this position. It is a prerequisite that the entrance door is provided with an external locking device to lock the entry permanently safe in a parked vehicle longer. This can be done, for example, by a remote-controlled central locking lock. In the case of a vehicle parked for a shorter period of time, the door can be locked by delaying the supply voltage without the external interlock. The brake will continue to be energized for this period.
  • the door is no longer fixed and can be manually moved by hand, but a mechanical emergency release eg via Bowden cable is no longer required.
  • the emergency unlocking takes place, for example, via a normally closed contact in the control line for the brake.
  • the emergency release can be reset either centrally or remotely with simple means, the decentralized reset of the emergency release, for example via an external relay connection.
  • the invention can even be completely dispensed with a brake as a blocking device when the drive motor can be short-circuited. About the occurring short-circuit torque of the drive motor so the door can be kept locked and a movement of the door can be prevented. This function is always guaranteed, even when the vehicle is stationary and not in operation.
  • the connection between the two contacts of the motor is preferably interrupted by a mechanical switch, the short-circuit torque is released and the door can easily be opened by hand without any problems.
  • the self-locking of the door is thus canceled by simply disconnecting the plus or minus line of the engine.
  • the lock is always present in the de-energized state of the motor, that is, a power failure has no changing influence on this.
  • the emergency release can always be carried out by pressing the short-circuit switch. It is possible to lock the entry / exit device, in particular a door, after interrupting the short circuit by switching back the switch.
  • the short-circuit switch according to the invention preferably operates directly without auxiliary power and thus also when the vehicle is stopped or when power is interrupted.
  • the advantages of using such a short circuit switch are on the one hand in the reduction of the necessary components for the emergency release, for otherwise, the short-circuit switch can be placed at any ergonomically favorable location, eliminating the need to lay standard Bowden cables or pneumatic lines.
  • a combination of a lock based on a short circuit and the use of a brake or mechanical locking is possible. This may be the case in particular if the short-circuit torque is insufficient to securely lock the door.

Abstract

L'invention concerne un dispositif d'entraînement (20) destiné à des mécanismes de montée et de descente pour des véhicules de transports publics. Ce dispositif comporte un dispositif de verrouillage pour le verrouillage et le déverrouillage des mécanismes de montée et de descente, et une unité d'entraînement (22) montée dans une colonne pivotante (24) qui tourne autour d'un axe de rotation Z-Z lors des processus d'ouverture et de fermeture et qui ouvre et ferme le mécanisme de montée et de descente, l'unité d'entraînement entraînant la colonne pivotante. Le dispositif est maintenu contre le véhicule par un élément de retenue (40) qui agit comme un contre-palier par rapport au couple de l'unité d'entraînement (22) et il comporte un élément d'actionnement (74) relié à l'unité d'entraînement (22) et au dispositif de verrouillage. Lors de l'ouverture du mécanisme de montée et de descente et de la génération d'un couple par l'unité d'entraînement, l'élément d'actionnement (74) est d'abord déplacé pour actionner le dispositif de verrouillage, avant que le couple de l'unité d'entraînement (22) ne soit transmis au mécanisme de montée et de descente.
