Definitions
- the invention relates to a cable window regulator for vehicles for lifting and lowering a window, with a drive for a cable drum, which is wrapped in a cable, a transmission being connected between the drive and the cable drum.
- Such a cable window regulator is known for example from DE 197 29 468 AI.
- the reduction gear of this cable window regulator consists of intermeshing drive and cable drum pinions, the shafts of which are arranged offset to one another.
- the disadvantage of the current transmission is the low efficiency.
- the present invention has for its object to provide a cable window regulator with a gearbox, which has an increased efficiency.
- this object is essentially achieved in that the transmission is designed as a spur gear transmission and the wheels of at least one intermeshing pair of wheels each have double and opposing toothing.
- the efficiency is significantly higher at 70% and more, with the gearbox also being self-locking. The self-locking is maintained until the gearbox is destroyed. This makes it practically impossible to press down the window pane when the drive is not actuated by external influences.
- the pair of wheels is a twin-worm gear, respectively Double screw gear trained.
- the number of teeth can vary between 1 and 12.
- the double and opposite toothing on each wheel is formed by helical or arrow teeth, which are arranged in the form of one or more turns on the respective wheel.
- This double and counter-rotating toothing absorbs the resulting axial forces in the wheel itself and does not transfer it to the housing or bearing, which explains the high efficiency of this special gearbox.
- the toothing of the respective wheel is advantageously arranged mirror-symmetrically to its central transverse plane.
- the axes of rotation of the wheels of the pair of wheels are aligned parallel to one another.
- a drive-side wheel has the toothing as external toothing, this external toothing being in engagement with the corresponding toothing of an inner shell of a ring gear.
- the gear is also the possibility of designing the gear as a planetary gear with a sun gear and one or more planet gears meshing with the sun gear, each of which has double and opposite toothing.
- Such a transmission has the advantage of a very small size.
- spur gears which are externally toothed are arranged on or on the shafts of the planet gears or on the shafts themselves, which mesh with the inner toothing of a ring gear.
- the outer casing of the ring gear carries a cable drum or a corresponding housing part or is itself designed as a cable drum.
- the ring gear can be rotatably supported by means of a central pin.
- the planet gears are connected via a web or planet carrier, the spur gears meshing with the internal toothing of the fixed ring gear and the cable drum being coupled to the web or planet carrier.
- FIG. 1 shows the basic structure of the intermeshing pair of wheels with double teeth
- FIG. 2 shows a section through a possible embodiment of a window lift mechanism with double teeth
- FIG. 3 shows a section along the line AA of the transmission according to FIG. 2
- Figure 4 shows a section through a further embodiment of a window lift mechanism according to the invention
- FIG. 5 shows a longitudinal section through the transmission according to FIG. 4.
- the meshing wheels 1, 2 of the pair of wheels 17, 18 have double toothing similar to a screw or worm. Due to the double and counter-rotating toothing, the axial forces that arise are absorbed in the wheel 1, 2 and are not transmitted to a housing or a bearing.
- the twin-wheel transmission is described, for example, in "Construction and Development",technikum, 2/97, page 80, or in EP 0 639 731 B1, which are expressly included in the disclosure content of the present application.
- the advantages of this type of gearbox are a high self-locking, which is maintained until the gearbox is destroyed, and the high efficiency.
- the wheels 12 are preferably toothed mirror-symmetrically to the central transverse plane 19.
- the drive takes place via the drive shaft 3, onto which, for example, a crank (not shown) of a manual window lifter can be attached.
- the drive shaft 3 represents the output shaft of an electric motor.
- the drive shaft 3 is connected to an externally toothed double screw wheel 4 with teeth 17, 18, as shown in FIG. 1.
- the double screw wheel 4 is arranged eccentrically with respect to an outer ring gear 5 and meshes on a circular segment (see FIG. 2) with the correspondingly configured double toothing on the inner shell of the outer ring gear 5.
- the ring gear 5 is connected to a housing part 6, which is radial on it outer Jacket serves as a rope drum for winding and unwinding the rope of the window regulator.
- the outer ring gear 5 or the housing part 6 is supported by a pin 7.
- the axes of rotation 20, 21 of the drive shaft 3 and pin 7 run parallel.
- the twin screw gear or twin worm gear is transferred to a planetary gear.
- the drive is via the shaft 8, which is rotatably connected to the sun gear 9.
- the sun gear 9 meshes with a planet gear 10.
- the gear set 9, 10 is in turn designed as a double helical gear set according to FIG. 1, whereby the gear arrangement is self-locking.
- On the shaft 11 of the planet gear 10, externally toothed spur gears 12 are arranged which mesh with the internal toothing of a ring gear 13.
- the output shaft 14 is connected to the ring gear 13.
- the outer contour of the ring gear 13 can in turn serve as a cable drum for winding and unwinding the cable of the window regulator, as a result of which the output shaft 14 can be omitted.
- a total of three planet gears 10 are provided.
- the planet gears 10 can also be mounted on fixed axes 11. It is also conceivable that the planet gears 10 are connected to one another via a web, the spur gears 12 arranged on one side of the planet gears 10 meshing with a fixed ring gear 13 so that the output movement can be tapped at the web or planet carrier.
