Definitions

  • the invention relates to a drive device for entry and exit devices of public transport vehicles.
  • the drive device comprises a drive unit, which is arranged within a rotary column and drives it, by rotating the rotary column in opening and closing operations of the entry and exit devices about its longitudinal axis.
  • Entry and exit devices on vehicles of public passenger transport are known in particular in the form of passenger doors, access ramps, sliding steps or the like.
  • suitable drive means are provided. Often these are mounted in the region of the door frame or door portals above a passage opening and serve to open and close doors.
  • doors are designed in the public transport as a sliding sliding doors, which perform during the opening and closing operation in addition to a pivoting movement and a lateral displacement.
  • Such door systems are for example from the EP 1 040 979 A2 and the EP 1 314 626 A1 known.
  • Drive devices for pure rotary or swing doors, where no lateral displacement takes place are usually arranged above or below the doors in the region of the door portal.
  • the DE 203 16 764 U1 describes, for example, the arrangement of a drive device in the upper region of a door portal.
  • the WO 2011/067001 A1 For example, before, between the drive unit and a holding member, with which the drive device is mounted on the vehicle to provide a coupling device.
  • the coupling device permits a rotation of the drive unit about the vertical axis. From a certain torque thus the entire drive unit rotates, which prevents damage to the drive motor and the transmission.
  • the coupling device disconnects only when a certain limit is exceeded, while the necessary torques for normal operation can be easily transferred.
  • a bearing is provided between the coupling device and the holding member, which allows a tumbling of the rotary column with the coupling device, so as to compensate for twisting and deflections of the rotary column due to movements of the vehicle.
  • self-locking reduction gear can be used, so as to achieve a blockade of the doors.
  • WO 2009/060085 A1 suggests WO 2009/060085 A1 to use a non-self-locking reduction gear, so that the doors of the vehicle can be moved manually, without this movement would be blocked by the self-locking of the transmission.
  • a separate blocking device is provided. But in order to open the doors in an emergency, the blocking device is controlled, so that their blocking effect can be lifted if necessary. The possibility of manual operation of the entry and exit devices is always guaranteed due to the low self-locking of the transmission in an emergency, it must be repealed to only the blocking effect of the blocking device.
  • DE 20 2008 001 066 U1 a driving device for the door of a public transport vehicle with a drive unit within a rotary column, which has two retaining arms for the attachment of the door.
  • a drive motor and two reduction gear are arranged in the rotary column and a Drehwegser chargedsvorraum the drive device has a transmitter for determining the position of a reduction gear. This information can be used to determine the position of the door as accurately as possible.
  • the EP 1 738 993 A2 also describes a drive for pivoting a arranged on the body of a vehicle flap or door.
  • the associated drive motor is switchable between a driving active state and a non-driving deactivation state. In the deactivated state, the transmission load acting on the drive motor can be detected by a sensor. When a defined load level is exceeded, a braking device is switchable to a EntblockierCloud so as to allow manual operation of the door.
  • the sensor is preferably integrated in the drive motor.
  • a door system having a force transducer for detecting forces occurring in the movement of a door.
  • a force transducer is attached to door edges, foot plates, door holders, etc.
  • overloading of components can be detected, which in particular can lead to an optical and / or audible alarm.
  • the present invention seeks to provide a drive device for entry and exit devices of public transport vehicles whose drive unit is protected from damage by excessively large external forces acting on the entry and exit device.
  • the drive device should be as robust, stable and compact as possible.
  • the drive device for entry and exit devices of public transport vehicles comprises a drive unit which is arranged within a rotary column and drives it by rotating the rotary column about its longitudinal axis Z-Z during opening and closing operations of the entry and exit devices.
  • the drive device is held on the vehicle and has a drive motor, a non-self-locking reduction gear and controllable blocking means. With the blocking means a rotation of the rotary column can be blocked.
  • the drive device further comprises a torque arm, via which the drive device is connected to the vehicle, wherein the torque arm acts as an abutment for a torque of the drive unit.
  • the applied torque of the drive unit opposite an abutment since the drive unit is fixed to a fixed component of the vehicle.
  • the output torque of the drive device can be transmitted to the rotary column to rotate it.
  • the drive device has a sensor, with which the size of an external force can be detected, which acts on the drive device.
  • the external force is applied by a person who wants to open the entry and exit device manually or even forcibly.
  • the size of this force can be measured directly or indirectly, for example by the deformation of a component by the external force.
  • the sensor does not need to measure the magnitude of the force itself, but can also sense its effects, which can then be used to draw conclusions about the magnitude of the force.
  • the senor according to the invention is mounted on the torque arm, which acts as an abutment for a torque of the drive unit. If a deformation of the torque arm occurs at this point, it means that on the drive device acts so high a force that it could cause damage to the drive unit.
  • the drive device further comprises means for evaluating signals from the sensor and for dissolving the blocking effect of the blocking means when a limit value for an external force detected by the sensor is exceeded.
  • the limit also corresponds directly or only indirectly to the size of the externally applied force. If the external force is measured, for example, based on the deformation of a component, the limit value corresponds to the degree of deformation and thus only indirectly to the magnitude of the external force.
  • the sensor used is, for example, a strain gauge.
  • This can be easily glued to a component of the drive device, such as the torque arm, which deforms at high external forces on the drive device.
  • the strain gauge registers this deformation and in deformations above a certain size, the blocking effect of the blocking agent can be canceled.
  • the strain gauge thus detects the size of an externally applied to the drive device force indirectly by the resulting deformation of a particular component.
  • the limit value for the resolution of the blocking effect of the blocking means in this case corresponds only indirectly to the size of an external force, because the limit value is the degree of deformation.
  • the senor is connected via a control unit in connection with the blocking means, wherein in the control unit at least one limit value for an external force detectable by the sensor is stored.
  • the control unit then has means for controlling the blocking means with which the blocking effect of the blocking means can be resolved when the at least one stored limit value for an external force detected by the sensor is exceeded.
  • the drive device further comprises means for controlling the drive motor when a limit value for a detectable by the sensor external force is exceeded, wherein the drive of the drive motor can be triggered in a direction opposite to the direction of the external force.
  • a limit value for a detectable by the sensor external force is exceeded, wherein the drive of the drive motor can be triggered in a direction opposite to the direction of the external force.
  • the limit value for dissolving the blocking effect of the blocking means differs from the limit value for driving the drive motor, so that countermeasure by the motor is activated, for example, only at higher forces.
  • the two limits can also be identical.
  • a bearing unit is provided between the drive unit and the torque arm, which allows a tumbling of the rotary column.
  • tumbling means a deflection in the X and / or Y direction.
  • the bearing unit comprises, for example, a spherical bearing, which is aligned with the rotary column.
  • the torque arm can also have two spherical bearings whose axes of rotation are at a level or are arranged in a horizontal plane. All three spherical bearings are then positioned at a very high point of the rotary column, so that the tumble of the rotary column is already effected directly in the field of attachment of the rotary column on the vehicle or on the portal.
  • This movable and flexible mounting of the drive device allows the installation of the drive device in different vehicles. It is even conceivable the drive device in a rotary column with low inclination, for example, to 5 ° inclined position to use.
  • the invention has the advantage that significantly fewer components are required and the invention can be realized with less effort. Furthermore, the drive device without safety coupling can be made more compact and is less maintenance intensive. Also does not rotate the entire drive device with what else could be detrimental in crowded vehicles, when persons or objects are leaning against the rotary column.
  • the limit value for dissolving the blocking effect can be adjusted individually for different vehicles or their conditions of use. If, for example, during operation of a vehicle, the limit value has been selected to be too high or too low, it can also be changed in a simple manner by reprogramming within a control unit.
  • the attachment of a strain gauge to a torque arm has the advantage that the sensor is easy to install here and reliably provides information about whether an external force could cause damage to the drive unit. If the torque arm deforms despite the intended bearing, this is an indication that a blockage should be lifted.
  • Fig. 1 shows a simplified schematic diagram of a drive device for entry and exit devices of a vehicle.
  • the associated drive unit 11 of the drive device 10 is accommodated within the outer tube of a rotary column 20, so that the drive device 10 comprises at least the rotary column 20 and the drive unit 11 accommodated therein.

  • the structure of a preferred embodiment of a drive device 10 according to the invention is shown in FIG Fig.2 shown, with only the upper part of the rotary column 20 is shown with the drive unit and the upper storage.
  • This part of the rotary column 20 has an outer tube 21, in which a drive motor 30 and a reduction gear 31 are housed.
  • An output element of the motor 30 is connected to an input element of the transmission 31, whose output shaft protrudes as a guide shaft 72 in a motor mount 70.
  • the guide shaft 72 is preferably non-circular for transmitting the torque from the reduction gear 31 to the motor mount 70. It may, for example, have a polygonal or polygonal cross-section.

  • the guide shaft 72 can also be displaceably mounted in the motor mount 70 in the Z direction in order to enable a displacement of the drive unit in the Z direction and thus to compensate for changes in length due to upsetting or stretching of the rotary column 20.
  • the entire drive device 10 according to the invention is advantageously constructed as a compact drive, in which the electric drive motor 30 and the reduction gear 31 are arranged axially one behind the other within the tubular housing 21 of the rotary column 20.
  • This slim design of the drive allows it to be visually appealing, e.g. to integrate at any point of the tubular door spin column. It is thus easily possible to place the drive depending on the vehicle conditions and connection possibilities, whereby the usual place for door drives, e.g. in the roof area, space for other components is created.

  • the movements of the rotary column 20 come about, for example, that the associated vehicle is compressed and twisted due to acceleration and braking 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 20 to take place. Since the drive device 10 is fixed to a fixed component via the attachment to the vehicle, such twisting and deflections of the rotary column 20 can have a negative effect on the drive unit.
  • the drive device 10 is attached via a holding member to a vehicle.
  • the drive device preferably comprises a torque arm 40, via which the drive device 10 is fastened to the vehicle.

  • a rotation path detection can furthermore be provided. This takes place advantageously via an incremental or an absolute encoder directly on the motor shaft of the drive motor 30 or an output shaft for the entry and exit device. If the drive device 10 is used, for example, for a passenger door, the rotation path detection can take place via the output shaft for a rotary column connection. The detection of the rotary path via the output shaft has the advantage that any material fractures can be detected within the drive and reported at an unwanted door opening.
  • the reduction gear 31 of the drive unit according to the invention is not self-locking, so that a manual operation of the entry and exit device is always guaranteed due to the low self-locking in an emergency.
  • a blocking device 32 is provided, which may for example be designed as a brake. This brake is in the embodiment of Fig. 2 axially below the motor 30. In order to open a door in an emergency, only the blocking effect of the blocking device 32 must be repealed. This leads to a high degree of security.

As soon as the detected force exceeds a certain limit, the blocking effect of the selected blocking means 32 is released so that the door can be opened. For example, therefore, the braking effect of a brake is resolved and / or the short-circuit torque of the motor 30 is canceled.
  • the senor 50 is attached to the torque arm 40 as shown in the three-dimensional view of FIG Fig. 3 is shown. It shows the Fig. 3 the upper pivot bearing 60, which allows a tumbling of the rotary column 20 and the two pivot bearings 41 and 42 of the torque arm 40th
  • the sensor 50 is formed for example as a strain gauge, which is glued to the torque arm 40 at a suitable location with a special adhesive.
  • a high external force which is for example applied manually by a person on a door, the torque arm 40 deforms, which is registered by the strain gauge 50. Once the deformation reaches a certain limit, this is interpreted as opening attempt of the door and the blocking effect of the selected blocking means 32 is released. The door can thus be opened without damaging the drive unit.
  • the senor 50 may also be mounted on another location of the drive device 10 that is suitable for measuring an external force is applied to an entry and exit device such as a door.
  • multiple sensors can be used.
  • a sensor 50 need not be positioned directly at a location at which such a force is applied, but it can also be positioned where an applied force on the drive device 10.
  • the sensor 50 could also be attached to the support arms 22, 23 or pivot 20 where it measures deformation of these components.
  • a plurality of sensors may be provided to detect effects of externally applied force at various positions.
  • the limit value for the detected external force can be stored in a control unit, not shown in the figures, which is in communication with the sensor 50 and the blocking means 32.
  • This control unit receives the signals from the sensor 50 and evaluates them. As soon as the stored limit value is exceeded, the control unit controls the blocking means 32 accordingly.
  • Forces below the limit value then mean normal operating loads on the respective entry and exit device, as may occur, for example, when people lean against doors. Of course, a door should not open in such cases.
  • forces above the limit value suggest an intended opening attempt, which could result in damage to the drive unit. In such a case, the door should open to prevent damage.
  • the limit value for the resolution of the blocking effect must be accurately determined. This can be done, for example, on the basis of experimental tests in which the effects on the drive device are measured for different external forces. However, the limit can also be determined theoretically.
  • the blocking effect of the blocking means 32 can thus be actively solved when the opening of an entry and exit means is desired and should therefore be allowed. However, it can also be solved passively, although the opening of an entry and exit device is not desirable, but should be allowed to prevent damage to the components of the drive unit.
  • the drive motor 30 is also actuated when a limit value of an external force on the drive device 10 is exceeded becomes. Preferably, it is driven in a direction opposite to the external force. Thus, it can be achieved that although a door is possible to open, but a complete opening is prevented by the engine.
  • the stored limit values for the resolution of the blocking effect of the blocking means 32 and for the drive of the drive motor 30 may be identical or different. With different limit values, it is preferably provided that the limit value for the resolution of the blocking means 32 is lower than the limit value for the control of the motor 30. The motor is thus activated only at very high forces.
  • the motor 30 is driven in the same direction in which the external force acts.
  • the door then opens automatically to prevent further action from vandalism.
  • further information can be processed when the motor 30 is actuated. For example, it may also be the case that a person forcibly tries to close an open door. If it is not possible to register by the selected sensor 50 whether a person is trying to open or close a door, but only that an external force is being applied, the control unit may provide the information as to what state the door is in. If the door is closed, it is an attempt to open the door, while with the door open it may be an attempt to forcibly close the door. The control of the motor 30 can then be carried out in accordance with the same or the opposite direction.
  • a strain gauge when a strain gauge is suitably attached to a torque arm 40, it is also possible to register deformations of the torque arm 40 in different directions. This indicates the direction of the applied force. Also, the attachment of multiple strain gauges is possible to better determine the direction of the applied force.
  • an alarm is also triggered when the limit for an external force is exceeded.
  • This alarm signal can be transmitted to the driver of the vehicle and / or a central office.
