Definitions

  • the invention relates to a drive device for a rotating column, in particular for moving pivoting door leaves on motor vehicles, in which the rotating column, which is rotatably mounted at its two ends in brackets, is designed as a hollow cylinder in which a screw gear is arranged, which is arranged by a completely arranged in the hollow cylinder in Pneumatic piston-cylinder drive can be driven in both directions of movement, which consists of at least two piston-cylinder units which are fixedly connected at one end to a holder of the rotary column and whose piston rod connected to a part of the screw gear is fixed in one end to the screw gear arranged and with one of the brackets connected axial guide device is guided non-rotatably.
  • Such a drive device is described for example in DE-A-2 538 529.
  • the known drive device has the disadvantage that the forces that can be generated to open and close the door are limited, since the rotary column in which the drive device is arranged must not exceed a certain maximum diameter. It is stated in connection with the known drive device that the piston-cylinder drive can also consist of several piston-cylinder units, but the problem of how the pressure medium supply to several piston-cylinder units should take place within the limited space does not is solved.
  • the invention has for its object to provide a drive device of the type mentioned in the preamble of claim 1, with which, despite the limited tube diameter of the rotating column, the minimum forces required to drive swing door leaves can be generated in both directions of movement.
  • the drive device assumes that the piston-cylinder drive should be arranged completely within the rotating column. Since the rotating column should not exceed a certain thickness, the first problem to be solved was to ensure a sufficiently large piston area on the piston-cylinder drive. This problem is solved by arranging two or more piston-cylinder units connected in parallel in the rotating column. Another problem to be solved was that it must be ensured that the torque generated there is absorbed at the connection point between the piston-cylinder drive and the screw gear so that the piston rod does not rotate.
  • the drive device according to the invention is structurally simple, requires very little space and it is possible to generate sufficient torque for driving the rotary column with relatively low pressures of the pressure medium, the counter torque occurring being absorbed in a particularly simple and effective manner.
  • the drive device according to the invention is primarily intended for moving swing door leaves, for example on buses or rail vehicles. However, it can be used in the same way as a drive device for a rotating column for moving trunk lids or flaps, such as those arranged on touring coaches. In this case, the rotating column is arranged horizontally.
  • FIGS. 1 and 2 for example on a bus (not shown in more detail) on a rotating column 1, which is rotatably connected to the door frame or the chassis 4 via brackets 2, 3, a swing door leaf 5 via pivot levers 6 and 7 in arranged in a known manner.
  • the swing door leaf 5 is further guided in a known manner with respect to the door frame or chassis by an only indicated guide device 8.
  • the opening angle is approx. 90 °.
  • the rotary column 1 which is designed as a hollow cylinder, is connected via a rotary bearing 27 to the holder 2 which is fixedly arranged on the chassis. Furthermore, a sleeve 9 is fixedly connected to the holder 2 via a connecting piece 10, which sleeve extends coaxially and in the longitudinal direction to the rotating column 1 over part of its length.
  • the piston-cylinder antenna Arranged within this sleeve 9 is the piston-cylinder antenna, which in the exemplary embodiment shown is made up of two piston-cylinder units. Of course, three or more piston-cylinder units can also be arranged in the same way.
  • the piston-cylinder units consist of a first jacket part 12, which is plugged onto the inner end of the connecting piece 10, a separator 20 plugged onto the other end of the first jacket part 12, a second jacket part 14 plugged onto the other end of the separator 20, the front end of which is closed by a further separating piece 22.
  • pistons 11 and 13 which are connected to one another via a piston rod 15 which is sealingly guided through coaxial bores of the separating pieces 20 and 22 and whose lower end in FIG.
  • a guide piece 30 which has a toothing extending in the axial direction which engages in a corresponding toothing on a counterpart 24 which is arranged non-rotatably at the lower end of the sleeve 9 in FIG. 3.
  • the guide piece 30 is in turn firmly connected to the drive spindle 25 of the screw gear.
  • the screw gear is not explained in more detail below and can be constructed, for example, as described in DE-PS 1 961 573.
  • the drive spindle can have helical grooves in which balls are arranged, which are mounted in a bearing cylinder 26 which is fixedly connected to the rotating column 1.
  • the compressed air for the two directions of movement of the piston-cylinder units is supplied in the following way:
  • the channel 29 opens directly into the interior of the jacket part 12.
  • the piston rod 15 has an axial bore 17 which on the one hand opens into the interior of the jacket part 12 and on the other hand is guided into the piston 13 and via a passage 18 and an outlet opening on the side of the piston 13 facing the piston 11 with the interior of the jacket part 14 communicates.
  • the bore 17 is passed further through the piston rod 15 and is connected in an analogous manner to the interior of the corresponding shell parts.
  • the channel 28 is connected to a feed channel 19 which runs between the outer wall of the jacket parts 12, 14 and the inner wall of the sleeve 9 and has an essentially annular cross section.
  • a feed channel 19 which runs between the outer wall of the jacket parts 12, 14 and the inner wall of the sleeve 9 and has an essentially annular cross section.
  • the connection between the upper and the lower area of the feed channel 19 takes place via a longitudinal groove 20a in the outer surface of the separator 20. If there are more than two piston-cylinder units the next separators are designed analogously. Only the last separating piece 22 has no longitudinal groove, but only an annular recess 22a.
  • the feed channel 19 is connected via passages 21 and 23 to outlet openings which are located in the separators 20 and .22 on the side facing the piston 11 and 13, respectively.
  • compressed air can be applied to the upper side of the pistons 11 and 13 in FIG. 3 via the channel 29, while the screw gear 25, 26 can be applied via the channel 28 and the supply channel 19 facing side of the pistons 11 and 13 can be acted upon with compressed air.
  • the individual parts of the piston-cylinder drive can be assembled in a simple manner by plugging them together and inserting them into the sleeve 9 from the side of the holder 2, the connection of the lower end of the piston rod 15 to the guide piece 23, for example via a Screw connection.
  • the sealing of the pistons 11 and 13 against the wall of the jacket parts 12 and 14, and the sealing of the spacer sleeve 16 arranged between the pistons 11 and 13, on the one hand, against the separating piece 20 and, on the other hand, against the piston rod 15, the sealing of the somewhat thickened lower end of the piston rod 15 against the separator 22 and finally the sealing of the jacket part 12 and the sleeve 9 on the connector 10 can be done by conventional ring seals.
