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 AI.
- 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.
- a drive device is known in particular for passenger doors, which builds very compact. Due to their narrow and elongated design, it is possible to integrate the drive device in a pivot column of a passenger door.
- 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 drive device is largely kept free by a special storage of loads caused by movements of the vehicle, the portal or the rotary column.
- the invention has for its object to provide a drive device of the type mentioned above, which takes no damage even with excessively large torques acting on entry / exit devices, in particular passenger doors.
- the drive device should be as robust and stable as possible and the production and installation simple and inexpensive possible. It is also essential that the drive device takes no damage by normal operating movements of the vehicle or the rotary column.
- a drive device for entry / exit devices for vehicles of public passenger transport with a drive unit which is in an opening and closing operations about a rotation axis 7.-7.
- rotating rotary column which opens and closes the input / output device, is arranged and this drives, wherein the drive unit is held via a holding member on the vehicle and the holding member acts as an abutment for a torque of the drive unit, wherein between the drive unit and the holding member is a coupling device is arranged, which allows a rotation of the drive unit about the axis of rotation ZZ when a limit value of the torque acting on the drive unit and between the coupling device and the holding member is provided a bearing that allows a tumbling of the rotary column with the coupling device and a rotation about the axis of rotation Currently prevented.
- the applied torque is opposed by an abutment, which is fixed to the drive unit to a fixed component of the vehicle.
- an abutment which is fixed to the drive unit to a fixed component of the vehicle.
- a bearing of the drive device or drive unit which takes into account that, due to the length of the rotary column, twisting takes place. fertilize and deflections of the same during operation are difficult to avoid.
- the movements of the rotary column come about by the fact that the vehicle is compressed or 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.
- 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, a rotation about the rotation axis 7.-7. however prevented. Tumbling is understood as meaning a deflection out of the axis of rotation ZZ in the X and / or Y direction. This function, so to speak, lifts a relative movement between the drive unit and the column.
- a movement in the Z direction, ie in the direction of the axis of rotation Z-Z is possible to compensate for a change in length by compression or extension of the rotary 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 coupling device For the function of the coupling device is crucial that it is functionally arranged between the support member and the drive unit, theoretically it could therefore also be positioned above the bearing, ie between the support member and the bearing.
- the inventive arrangement of the bearing between the coupling device and the holding member but has the significant advantage that the movement degrees of freedom caused by the camp not only protect the rotary column, but also the coupling device from damage and wear.
- the tumble of the rotary column with the drive device and the coupling device is, so to speak, at the highest point, already effected directly in the field of attachment of the rotary column with the associated components already on the support member or portal.
- this arrangement can be realized with only relatively few and robust components. The space requirement is low and the storage has little play.
- 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.
- the drive device or the transmission is protected by the fact that the entire drive unit rotates from a certain torque and thus damage is avoided.
- the decisive factor is that the coupling device but only disengages when a force acting on the drive unit torque exceeds a limit, but the necessary torques for normal operation are easily transmitted.
- the coupling device thus serves as a safety coupling for the drive unit or for the transmission.
- the coupling device may be designed as a slip clutch, but it is also conceivable a hydrodynamic or electrodynamic coupling. Also, a so-called break bolt coupling can be used, break in the bolt when reaching the limit torque. This design is certainly useful for certain applications, but has the disadvantage that after such a torque exceeded an exchange of the bolts is necessary.
- two coupling elements each have latching elements, for example toothings, via which they engage with one another and can transmit a torque.
- Conceivable is the use of clutch plates, which lie on top of each other and are in normal operation in engagement. At least one of the clutch plates is acted upon by a restoring force, for example by a plate spring. If the torque limit is exceeded, the clutch discs overcome the restoring force twisting over flanks of the teeth against each other and are ultimately disengaged. The torque can not be transmitted and the clutch plates slip over the gears until the torque decreases again and the locking elements come back into engagement.
- the coupling device is designed as a blocking body coupling. This means that additional bodies are arranged between the coupling elements which transmit the torque. For example, this may be spring-loaded balls, bolts or claws, which slip on reaching the limit torque of corresponding grooves and thus allow rotation of the coupling elements.
- the coupling device it is possible to design the coupling device such that it disengages only in one direction of rotation, but blocks in another direction of rotation.
- This can be achieved, for example, for the configuration of the tooth flanks or in the case of a blocking body coupling of the grooves.
- the blocking body for example the ball
- the flank is for example just made to block the movement of the ball.
- 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, that is approximately at the same position of the axis of rotation 7.-7. be arranged. This prevents tension and stress on the bearings and causes the movement of the drive unit and rotary column to run as parallel as possible.
- 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 around ZZ 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. Such 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 e.g. a planetary gear, 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 is rotated.
- an outer tube for the drive unit and the torque support in the area of the bearing can be omitted.
- the blockade is thus 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 electrically 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.
- any other suitable blocking device can be used, for example, the brake can act on the drive shaft of the drive motor by means of spring force and be electromagnetically releasable.
- a so-called high-active brake is also possible.
- Such a brake is also known under the term 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 z. B. done by a remote-controlled central locking lock.
- 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 emergency release, on the other hand, the short-circuit switch to any ergonomic place cheaper, laying of conventional Bowden cables or pneumatic lines deleted.
- 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.
- the switchable short circuit can be advantageously ensured by special windings of the motor windings, which are provided exclusively for the production of the short circuit. By special windings and an increased braking effect or Verrieglungs Bark can be achieved.
- the output element of the reduction gear can be connected to a lifting rotary unit, a known per se component, which is used in particular for exterior swing doors. About the door stroke doing a positive connection of the door leaf with the door portal via locking wedges.
- the total reduction gear may for example be divided into two individual gears, which are coupled together by a disengageable coupling device.
- the controllable coupling device can be designed as a spring-engaging coupling device, which is connected to a manually operable emergency unlocking device.
- the first reduction gear is connected to the drive motor and the first coupling half together axially by means of spring force of a compression spring with the second coupling half and the second reduction gear.
- the construction of the coupling device is extremely simple and can be realized with significantly fewer components.
- the outer diameter also remains significantly smaller, since the connection point of the Bowden cable is provided centrally in the housing.
- a support element can be positively connected to the drive unit. tied and rotatable about a clutch bearing on a support member which is fixedly connected to the vehicle to be attached.
- the support element has axially extending recesses in which coupling balls are mounted.
- the coupling balls each extend into axially extending guides of the bearing housing, whereby a torque can be transmitted.
- the bearing housing is firmly connected to the support member of the vehicle, the coupling balls are held in position via a pressure plate during normal operation, wherein the pressure plate itself is in turn subjected to a spring force. It has proved to be particularly advantageous to use a flat plate spring as possible because it has a very flat force characteristic.
- the support element may also be formed by a plate-shaped component with recesses in which the balls are mounted.
- a plate-shaped component is easy and inexpensive to manufacture.
- the coupling balls remain by the spring force in the recesses and guides, but the torque exceeds the limit, the balls slide along side edges of the recesses in the axial direction, whereby the support member and thus the drive unit rotates together with rotary column. A rotation can take place until the next recess into which the ball is pressed due to the restoring force of the spring.
- the limit that is, the torque at which the balls can move out of the recesses, can be determined by the magnitude of the force of the plate spring package and the angle of the side edges of the recesses. Likewise, the permissible path can be specified when the limit value is exceeded by way of the number of recesses. In a particularly advantageous embodiment, eight recesses with eight balls are provided at 360 °, resulting in a path of 45 °.
- a monitoring element can be provided which registers uncoupling of the coupling device. It is conceivable a switching element which engages in recesses of the support element and is thus actuated by a rotation of the support element.
- the issuing signal may be, for example Give the driver feedback on vandalism, or otherwise evaluated in the door control.
- the bearing arranged directly on the holding component has a total of three ball-and-socket bearings.
- the first pivot bearing is aligned with the axis of rotation 7.-7. and allows pivoting of the rotary column from the vertical in all directions.
- a torque support is provided which also prevents the coupling device from rotating about the rotation axis Z-Z.
- the torque arm has two further ball joint bearings, arranged outside the axis of rotation Z-Z and connected via an intermediate element with an outer side of the coupling device.
- the drive torque is passed through the torque arm in the holding member and from there into the portal.
- All three bearings are designed as ball and socket bearings, so that despite the prevention of the rotational movement of the coupling device by the torque arm pivoting or tumbling of the rotary column in all directions is possible.
- the arranged in the torque arm ball joint bearings are advantageously arranged such that the axes of rotation of all three bearings are arranged at approximately the same height or in a horizontal plane. As a result, unfavorable lifting conditions are avoided and ensures optimal balance of power. In principle, however, an offset of the pivot bearing is possible in terms of their height.
- the coupling device which receives on its side facing away from the bearing an output shaft of a transmission rotatably about a toothed shaft receiving, but in the longitudinal direction of the rotary column, ie along the axis of rotation ZZ displaced is connected to the coupling device.
- the shaft receptacle itself is rotatably mounted in a further receptacle enclosing the shaft receptacle, which turn in turn is rotatably positioned in a bearing sleeve of the drive device.
- the receptacle is firmly connected to an outer tube or the rotary column itself, the bearing sleeve serves the tube diameter compensation between the inner by measuring the outer tube or the rotary column and the outer diameter of the receptacle.
- the bearing sleeve is screwed to the outer tube or the rotary column and running as a wear part interchangeable.
- the entire coupling device is on the Abbtiebswelle and the shaft receiving axially along the axis of rotation 7.-7. slidably, which allows a length compensation of the entire rotary column with the drive device.
- the coupling device closes down over the motor shaft to the transmission of the drive device.
- the engine and a brake.
- the brake can be followed by another, simpler constructed transmission, which is connected to a transmitter for a rotary path detection, for example, an incremental or absolute encoder.

- FIG. 1 shows, in a simplified schematic diagram, a drive device 20.
- a drive unit 22 is accommodated in a rotary column 24.
- the rotary column 24 has retaining arms 26 for the attachment of a door, not shown, and is rotatably supported by a bottom bearing 28 on a base, usually a vehicle floor.
- a rotary bearing 38 is shown, via which the rotary column 24 rotatable about a longitudinal axis 7.-7. is stored in a bearing 34.
- the drive unit 22 is rotatably connected via a rotary column bearing 30 with the rotary column 24, so that via the rotary column bearing 30, a rotational movement of the rotary column 24 can be effected.
- a guide shaft 32 extends into the bearing 34 and is rotatably connected via a drive unit bearing 36 with this.
- the drive unit bearing 36 can be embodied, for example, as a ball-and-socket joint bearing and serves to receive the torque of the drive unit 22, which in turn is firmly connected to a holding component 40 (compare FIGS. 4 and 5).
- FIG. 2 shows a drive unit 22 constructed as a compact drive and arranged in the rotary column 24, for example for a passenger door, in which, within a slim, tubular housing 42, in the axial direction. one behind the other an electric drive motor 44 and a gear 46, preferably designed as a reduction gear, shown as a three-part planetary gear, are arranged. Connected to the drive motor 44 is a brake 48, which is also accommodated within the housing 42 and can be designed as a spring-engaging and electromagnetically and mechanically releasable "low-active brake” or as a "high-active brake".
- the gear 46 is not designed to be self-locking.
- An unrecognizable output element of the drive motor 44 is connected to a likewise not recognizable input element of the transmission 46, whose output shaft 54 guide shaft 32 is connected via the rotary column bearing 30 with the rotary column 24.
- the rotary column 24 tapers below the drive unit 22.
- the guide shaft 32 extends from the housing 42 into the bearing 34, the bearing being connected to the support member 40 of the vehicle.
- the torque generated by the drive motor 44 is transmitted via the gear 46 to the transmission output shaft 54.
- only the brake 48 must be solved, after which the manual operation of the passenger door due to the lack of self-locking of the transmission 46 is readily possible.
- brake 48 may be provided for locking a short-circuiting device that short-circuits the motor windings of the drive motor 44 for locking.
- All electrical and mechanical connection elements e.g. If necessary, a Bowden cable for manual unlocking of the brake, are arranged within the housing 42. Also, when using the drive device 20 in a lifting rotary unit, a sensor may be provided for Huber upset.
- Fig. 3. shows a second embodiment of the drive device 20, a coupling device 72 is not shown.
- the transmission output shaft 54 acts as a guide shaft 32, projects into the bearing 34 and is rotatably mounted there.
- the housing of the planetary gear 46 is rotatably connected to the rotary column 24. If the drive motor is energized, that also rotates Housing of the planetary gear 46 of the drive unit 22, whereby the rotary column 24 is rotated.
- an outer tube 42 (see Fig. 2) omitted.
- Figures 4, 5 and 6 show the storage of the drive unit 22 on the support member 40 via the bearing 34, wherein in FIG. 5, the coupling region shown enlarged.
- the inventive bearing of the rotary column 24 via the first pivot bearing 64, in which the rotary column 24 about the longitudinal axis 7.-7. can turn and balance wobbling movements.
- the guide shaft 32 which is slidably mounted in a shaft mount 66 in the Z direction, but transmits the torque of the drive unit 22 via a non-circular outer contour.
- the shaft receptacle 66 is rotatably mounted in a further receptacle 67 surrounding the shaft receptacle 66, which in turn is rotatably positioned in a bearing sleeve 70 of the drive device 20.
- the bearing sleeve 70 is fixedly connected to an outer tube 25 of the rotary column 24.
- the bearing sleeve 70 serves the diameter balance between the inner diameter of the outer tube 25 in this area and the outer diameter of the receptacle 67 and is screwed by screws 68 to the outer tube 25.
- a coupling device 72 is disposed below the first pivot bearing 64 and connected via the shaft receiver 66 with the lower rotary column 24.
- the shaft receiver 66 has a support element 74 with essentially horizontally arranged depressions 80 which are aligned with depressions 82 which are arranged in a pressure disk 88 (compare FIGS. 7 to 12).
- a plate spring 86 is further arranged as a restoring force element, which exerts a force on the coupling balls 84 via the pressure plate 88, and pushes them into the depressions 80 or holds them there. Further details on the construction of the coupling device 72 can be found in particular in FIGS. 7 to 11.
- the clutch housing 78 is connected to an inner bearing housing 76, which is also part of the first pivot bearing 64.
- the first pivot bearing 64 is enclosed by an outer bearing housing 77.
- the bearing 34 has, in addition to the first joint bearing 64, a second joint bearing 65 and a third joint bearing 69, which are arranged in a torque support 71. Via an intermediate element 73, the two outer joint bearings 65, 69 are connected to the coupling device 72. A rotation of the coupling device 72 is effectively prevented by the torque arm 71, but a tumbling of the rotary column is on the three pivot bearings 64, 65, 69 possible.
- the axes of rotation of the three joint bearings 64, 65, 69 are arranged at a height or in a plane, which causes a favorable balance of forces.
- connection cables can be quickly and easily attached via a cable or Bowden cable guide 79, also ordinary cable ties can be taken to help.
- the gear 46 Adjoining the coupling device 72 in the direction away from the holding member 40 (down), the gear 46, preferably designed as a reduction gear on. It is followed by the drive motor 44 and the brake 48. Furthermore, a secondary gear 43 is shown, which is connected to a not shown encoder for a Drehweger reported.
- the second gear 43 is a simple, for example made of plastic gear, which is not used for torque transmission, but only for the rotation path detection.
- an associated encoder for example, an incremental or absolute encoder is.
- the sectional views in Figures 7 to 11 illustrate the structure of the coupling device 72.
- the support member 74 has axially extending recesses 80 which are aligned in normal operation with also axially extending guides 82 which are arranged in the bearing housing 76.
- the plate spring 86 is further arranged as a restoring force element, which exerts a force on the coupling balls 84 via the pressure plate 88, and pushes them into the depressions 80 or holds them there.
- FIG. 7 shows that a horizontally extending annular section 90 projects between the coupling balls 84 and the thrust washer 88.
- the guides 82 extend axially through this annular section 90, so that the coupling balls 84 can come into contact with the pressure disk 88.
- FIGS. 8 and 9 show a switching element 92 with a switching arm 94, which engages in recesses 96 arranged on the outer circumference of the support element 74. If the support element 74 rotates, the switching arm 94 is moved and the switching element 92 is switched.
- the signal associated therewith may, for example, give a driver feedback about vandalism or otherwise be utilized.
- FIGS 10 and 11 illustrate in a much simplified schematic representation of the operation of the coupling device 72. Visible u.a. a coupling ball 84 which is arranged in the normal state according to Figure 8 in a recess 80 and projects into the guide 82. The pressure disk 88 holds the coupling ball 84 in the recess 80.
- FIG. 11 shows the state which results when the limit value of the applied torque is exceeded.
- the support element 74 has rotated and the coupling ball 84 has been driven along a side edge 98 upwards in the direction of the pressure plate 88.
- the torque has exceeded the restoring force of the plate spring 86, whereby the coupling ball 84 is rolled in the guide 82 to a vertex 100 between two recesses 80.
- the support member 70 can rotate until the limit is exceeded again and the coupling ball 84 is pressed back into one of the following recess 80.
- Figure 12 illustrates the structure of the drive device 20 in an exploded view.
