  • Such gear arrangements are known in the prior art. They serve to open or close a tailgate or a door or the like on a motor vehicle.
  • the transmission has a drive motor.
  • a reduction gear is arranged downstream of the drive motor.
  • a worm gear is usually used as the reduction gear, so that the worm applies a sufficiently high torque to open the flap or door.
  • means in the form of a coupling are provided. These means separate the drive motor or the worm gear from the actuating gear.
  • the actuating gear can be moved along empty during manual actuation. However, the drive motor or worm reduction gear is uncoupled.

  • the object is achieved by the invention specified in the claims, not only the main claim, but also the formal subordinate claims having independent significance.
  • Claim 1 initially and essentially provides that the transmission, which can be a reduction gear in particular, is a planetary gear.
  • Such transmissions also known as planetary transmissions, have three shafts. In terms of transmission technology, these shafts can have the same priority. However, there is also provision for a reduction or a reversal of the direction of rotation to take place between the individual shafts.

  • a gear rim forms the gear housing and is non-rotatably connected to the environment.
  • the other ring gear forms the rigid gear wheel on which the output takes place.
  • the reduction takes place in that the toothing of the toothed rings has a different number of teeth.

  • the gear arrangement has a plurality of shaft gears, in particular two shaft gears located coaxially one behind the other, each of which is driven by a motor. These can be arranged in a tubular housing.
  • the housing can be a hollow profile body.
  • Output shafts which can be connected to an actuating gear, preferably protrude from the two mutually facing end faces of the hollow profile body.
  • gears are also possible, for example the planetary gearing could also be formed by the planetary gearing already mentioned above, in which one or more planet gears are arranged in a row between an inner and an outer sun gear and are connected to a planet carrier. It is also possible to use a bevel gear as a planetary gear.
  • the third shaft is preferably formed by the housing.
  • An emergency drive unit can engage on the third shaft; this can be, for example, a hexagon adapter which, if the moving part is a motor flap, is accessible from the outside, so that an auxiliary drive, for example in the form of a cordless screwdriver or a drill, is attached to it ⁇ can be set to open the flap by motor. This is optimally done when the first shaft connected to the motor is stopped or even blocked.
  • the auxiliary drive can also support the engine. With the auxiliary drive formed by the cordless screwdriver or the drill, even the slip clutch can be overcome.
  • the slip clutch can also be used to acoustically indicate a malfunction. For this purpose, it is provided that the slip clutch emits noise when triggered. However, noiselessly acting slip clutches are also provided.
  • the transmission used according to the invention is a three-shaft transmission which can be operated in a two-shaft mode or in a three-shaft mode.
  • the transmission preferably has no self-locking.

  • the number of teeth are matched to one another in such a way that diametrically opposite zones of the two internal toothings 14, 17 are aligned with one another, so that a simultaneous tooth engagement of the external toothing of the elastic gearwheel 7 is ensured. If the shaft generator 6 is now rotated, the engagement zones move in the direction of rotation through the respective internal toothings 14, 17. As a result of the difference in the number of teeth, a rotational movement is transmitted to the driven ring 4 while the fixed gear 3, 3 'is held.

  • the inner surface of the outer part 3 1 of the fixed wheel has a plurality of latching niches 11.
  • the inner part 3 of the fixed wheel has associated radial bores in which compression springs 12 lie. These compression springs act on locking balls 10 which normally lie in the niches 11. When a limit torque between the inner ring 3 and the outer ring 3 'is exceeded, the locking balls 10 are controlled from the locking recesses 11 so that the two ring parts 3, 3' can be rotated against each other.
  • the fixed ring 3, 3 ' is connected to the transmission housing 19 by means of a coupling 13.

  • the coupling between the third shaft and the frame can be varied between the freewheel and the gearbox-fixed.
  • FIG. 13b shows manual operation in which the movable part is actuated by hand.
  • the second shaft 4 then becomes the drive shaft.
  • a torque or a rotation is transmitted to the motor 1 via the first shaft 5.
  • the gear member 3 which has so far been fixed on the frame, is released, so that the gear unit operates in three-shaft operation.
  • the directions of rotation of the motor and manual drive can be the same or opposite.
  • FIGS. 13d to 13f relate to the emergency drive with the motor switched off and without actuation on the third shaft 3.
  • FIG. 13d shows the state in which the motor engaging the shaft 5 is switched off and there is no actuation on the shaft 3.
  • 13e shows an indefinite state in which both the shafts 3 and 5 can rotate freely.
  • 13f demonstrates how a rotational movement of the second shaft 4 is transmitted to the first shaft 1 by means of torque regulation or inhibition of the third shaft 3.
  • Figures 13g to 13e relate to the emergency drive with the engine switched off.

According to FIG. 13g, this can be done together with a manual actuation of the movable element or, according to FIG. 13h, only by actuating the emergency drive, which has been designated with the reference number 20 in the previous exemplary embodiments and which acts on the third shaft 3.
  • Fig. 13e shows the state with the motor shaft locked. In this case, the motor shaft 5 can be completely blocked. Then the entire power, which is introduced via the emergency unit via the third shaft 3, for delivering the movable element is output via the first shaft 4.

  • Motor shaft 5 and third shaft 3 thus act together on the output shaft 4 for actuating the movable element.
  • the operation of the device is as follows: If a closure equipped with the transmission is to be operated manually, the clutch 13 is in their open state. A rotation then transmitted to the output ring 4 by the actuating gear 9 is essentially transmitted directly to the fixed gear 3, 3 '. This can turn freely because of the released clutch 13. This can be done both in the opening and in the closing direction of the flap or door equipped with the lock. If the flap or door is to be opened by a motor, the clutch 13 is brought into effect in conjunction with the motor current supply in such a way that the fixed ring 3, 3 'cannot rotate relative to the gear housing 19 or the body.
  • the clutch 13 can also be controlled electrically, for example via electromagnets, pneumatic cylinders or stepper motors.
  • the rotation of the drive shaft 5 of the motor 1 is transmitted to the output shaft 4 with a strong reduction. It is advantageous that approximately the same torques occur in the area of the overload protection 10, 11 that also occur on the output shaft 4. If the output shaft 4 is blocked from movement, the overload protection device 10, 11 triggers in the manner described above in such a way that the balls 10 emerge from the niches 11 opposite them. Otherwise, the actuating gear 9 is optionally moved by the motor 1 in one of the two directions.
  • the energization of the clutch can be coupled directly to the energization of the motor 1.
  • FIGS. 7 to 12 have the special feature of an emergency drive 20.
  • This can be operated from the outside with the flap closed or also open.
  • Fixed gear 3 which forms the third shaft of the transmission and which is normally held in place on the frame, will be rotated with it.
  • the auxiliary drive acts either as a motor support or automatically if the motor shaft 5 is blocked. Because of the slip clutch provided between the parts of the fixed wheel 3, 3 ', no special switching is necessary.
  • the emergency drive begins to act as soon as the drive unit, not shown, overcomes the slip clutch. All of the features disclosed are (in themselves) essential to the invention.
  • the disclosure of the application is hereby fully incorporated into the disclosure content of the associated / attached priority documents (copy of the prior application), also for the purpose of including features of these documents in claims of the present application.
