Definitions

  • the invention relates to a drive, in particular an adjustment drive for motor vehicles, with a rotatably mounted drive member, a rotatably mounted output member which is coaxial with the drive member and a wrap spring which is supported against the inner circumferential surface of a hollow cylindrical element which is coaxial with the members, one of the members being non-rotatably connected to a first claw part is connected, which presses against one of the possibly inwardly bent ends of the wrap spring in the sense of widening of the wrap spring when the wrap spring and claw part are rotated accordingly.
  • a drive of this type is known (for example DE-OS 25 24 583 and DE-PS 487 155).
  • the hollow cylindrical element as part of a drive housing is stationary and is used in conjunction with the wrap spring and on both links brought claw parts as a wrap spring brake for a motor vehicle window regulator.
  • the two links are coupled via the interlocking claw parts.
  • the object of the invention is to provide a drive of the type mentioned at the outset, in which the drive and driven member are connected to one another in a rotationally fixed manner via an easily releasable, particularly simply constructed coupling.
  • the other link is rotatably connected to the hollow cylinder element. If the two links are rotated against each other in such a way that the first claw part presses against the wrap spring in the sense of widening, this leads to the wrap spring being pressed against the inner circumferential surface with a radial force which increases with the torque acting between the links. Accordingly, one obtains a reliable rotational coupling of the links with a mutual twisting in the specified sense. It does not matter whether the hollow cylinder is connected to the drive element or to the output element in a rotationally fixed manner. The rotary coupling between the two links is achieved in that the wrap spring is moved away from its non-positive pressure position on the inner peripheral surface.
  • a separate, rotatably mounted, with the links coaxial disengagement element is provided, which is formed with a second claw part, which presses with a corresponding mutual rotation of the wrap spring and the second claw part at one of the ends of the wrap spring in the sense of a diameter reduction of the wrap spring .
  • the rotational coupling between the links which is also effective in both directions of rotation, can be released in a simple manner by corresponding actuation of the decoupling element.
  • a further preferred embodiment of the invention is characterized in that the preferably electric motor-driven drive member is connected in a rotationally fixed manner to the hollow cylinder element, in that the first claw part, which is connected in a rotationally fixed manner to the output member, is depending on the rotational position at one or the other end of the wrap spring in each case in the sense of an expansion of the wrap spring presses that the second claw part presses on one or the other end of the wrap spring in the sense of a diameter reduction of the wrap spring depending on the rotational position and that the decoupling element can be connected to an auxiliary drive (preferably a manual drive).
  • auxiliary drive preferably a manual drive
  • the output member can be rotated in the desired manner in both directions of rotation by appropriate rotation of the decoupling element, the rotary coupling between the drive member possibly blocked by the stationary electric motor and the output member being released.
  • the drive element is carried along by the disengaging element in that the second Presses claw part against the first claw part via a wrap spring end and takes it with it.
  • the drive according to the invention is immediately ready for operation again, with only the auxiliary drive, for example a hand crank, possibly being separated from the decoupling element.
  • the entire arrangement is compact because the decoupling element is mounted coaxially to the links.
  • the disengaging element can be connected to the auxiliary drive via a plug-in coupling; such a coupling is easy to operate and requires little installation space, especially if the decoupling element is provided with an internal polygon for a manual control element.
  • the drive element be axially forward on an end face perpendicular to its axis of rotation standing, distributed on a circumferential line, between which engages correspondingly formed on the hollow cylindrical element webs, wherein in the circumferential direction between the webs each have a spring element, preferably a rubber element.
  • a particularly compact arrangement in the axial direction is obtained in that a bearing collar for the rotary mounting of the hollow cylinder element or of the drive element is formed on the drive element or on the hollow cylinder element.
  • the hollow cylinder element is provided with a metallic insert sleeve having the inner peripheral surface, low-wear operation and a consistently high coefficient of friction between the wrap spring and the inner peripheral surface are achieved.
  • the hollow cylinder element itself can be manufactured inexpensively from less wear-resistant material, for example from plastic.
  • the first claw part is formed in the region of the two ends of the wrap spring with a flat, preferably approximately dovetail-shaped driver, which is attached to an output shaft and is perpendicular to the axis of rotation of the links and projects radially beyond the inside wrap spring diameter.
  • a flat, preferably approximately dovetail-shaped driver which is attached to an output shaft and is perpendicular to the axis of rotation of the links and projects radially beyond the inside wrap spring diameter.
  • the two drivers can be congruent and / or in one piece with the An drive shaft be formed.
  • the drive according to the invention is particularly suitable as a drive for a motor vehicle window regulator.
  • the output member is connected in a rotationally fixed manner to a pinion which meshes with a threaded cable of a cable window lifter or a toothed segment of a rod window lifter.
  • the output member can alternatively also be connected in a rotationally fixed manner to a cable drum for the cable of a cable window lifter.
  • the disengaging element is formed with a partial hollow cylinder which forms the second claw part and is arranged between the wrap spring and the output shaft passing through the wrap spring, the axially extending edges of which cooperate with the radially inwardly bent ends of the wrap spring.
  • a simple mounting of the decoupling element which in turn requires only little installation space in the axial direction, is formed in such a way that the decoupling element is rotatably mounted in a bearing opening of a drive housing with an axial bearing bolt which may be formed with the internal polygon.
  • the decoupling element is rotatably mounted in a bearing opening of a drive housing with an axial bearing bolt which may be formed with the internal polygon.
  • To increase the endurance strength can always be p stored el- element additionally entraining Auskup namely on the first claw part by means of a bearing on the periphery of one of the carrier with the members in normal operation, on the drive shaft mounted drive plate adjacent Federal.
  • the drive shown in FIGS. 1 and 2, generally designated 10, establishes the connection between an electric drive motor, not shown, on the motor shaft of which a worm 12 shown on the right in FIG. 1 is fastened and a threaded cable window lifter in a motor vehicle, the threaded cable 14 in Fig. 1 is drawn lower left.
  • a drive member 16 in the form of a worm wheel meshing with the worm 12 a hollow cylindrical element -18, which couples torsionally vibration-damped to the drive member 16 and via a damping rubber part 20 a wrap spring 22, which is supported on the inner circumference of an insert sleeve 24 inserted into the hollow cylindrical element 18, and an output member 26, the upper end of which in FIG. 1 is provided with two drive disks 28, which form a first claw part and interact with the wrap spring 22, and at the lower end of which a pinion 30 engaging in the threaded cable 14 is pushed in a rotationally fixed manner.
  • the disengaging element 32 serves to enable manual operation of the window lifter in the event of a malfunction, for example in the case of a defective drive motor.
  • the rotary parts 16 to 32 described above are mounted in a two-part housing with a lower housing base 34 in FIG. 1, a housing cover 36 with an intermediate sealing ring 38 and a cover 40 attached to the underside of the housing base 34, which serves as a guide for the threaded cable 14 and covers the threaded cable 14 and the pinion 30 against contamination downwards.
  • the housing can be made of plastic or metal.
  • FIG. 3 The vibration-damped, rotationally fixed connection between the drive member 16 and the hollow cylinder element 18 is illustrated in FIG. 3. .
  • the hollow cylinder element 18 is formed with a bearing disc 44 perpendicular to the axis of rotation 42 in FIG. 1, from which a hollow cylinder section 46 adjoins upwards in FIG. 1 (indicated by dotted lines in FIG. 3) in the, as already mentioned , the insert sleeve 24 is inserted.
  • the bearing disc 44 is formed with a central bearing opening 48 with which the hollow cylinder element 18 is rotatably mounted on a correspondingly dimensioned bearing collar 50 of the drive element 16.
  • the bearing collar 50 engages around neck bearing 52 is formed, as in Fig. 3 can be seen on the bearing disc 44.
  • the shape of the wrap spring 22 inserted into the insert sleeve 24 can be seen from FIGS. 1 and 2. Accordingly, the wrap spring 22 is wound in the manner of a solenoid, with both ends, the upper visible end 72 in FIG. 1 and that only in FIG. 2 recognizable lower ends 74 are bent radially inwards.
  • the outer diameter of the relaxed wrap spring 22 is slightly larger than the In diameter of the insert sleeve 24, so that the wrap spring 22 inserted into the insert sleeve 24 presses radially outward against the inner peripheral surface 76 of the insert sleeve 24.
  • the driving disks 28 interact in accordance with the respective rotational position, specifically the driving disk in FIG. 1 with the upper end 72 and the lower driving disk 28 with the lower end 74.
  • the two driving disks 28 are each formed with an approximately dovetail-shaped driver 78 which, as shown in FIG. 2, extends to the inner circumferential surface 76 of the insert sleeve 24. In this way, it is achieved that the ends 72 and 74 are not bent over by the corresponding drivers 78 even at high torques, since the drivers 78 with their outer corners directly apply the corresponding torque to the ends 72 and 74 in each of the bent ends Transfer circumferential wrap spring section.
  • the two catches 78 prevent the windings of the wrap spring 22 lying between them from moving axially upwards or downwards.
  • the two drive disks 28 are pushed onto both sides of a collar 80 of enlarged diameter of the output shaft 68 and are soldered or welded there.
  • the drive plates can also be formed in one piece with the output shaft.
  • the pinion 30 is non-positively pushed onto a reduced-diameter, corrugated section 82.
  • the disengaging element 32 consists of a circular disk 84 perpendicular to the common axis of rotation 42, from which an axial bearing pin 86 projects upwards in FIG central polygonal socket 88 is provided for receiving a corresponding external polygon of a Hilfsbetätigun not shown s finallyls g.
  • the bearing pin 86 is rotatably mounted in a corresponding bearing opening 90 in the housing cover 36.
  • a partial hollow cylinder 92 whose cylinder axis coincides with the axis of rotation 42, extends downward from the circular disk 84. As can be seen in FIG. 1, the partial hollow cylinder 92 almost reaches in the axial direction up to the bearing disk 44 of the drive member 16.
  • FIG. 2 corresponds to a circular ring from which a sector has been cut out.
  • the edges of the partial hollow cylinder 92, which run in the axial and radial directions, are designated by 94 in the figures. As can be seen from Fig. 2, these edges 94 cooperate with the corresponding ends 72 and 74 of the wrap spring 22 depending on the direction of rotation, as will be explained in more detail.
  • FIG. 1 also shows a collar 96, which is formed at the upper axial end of the partial hollow cylinder 92 and protrudes slightly radially inwards and rests on the outer circumference of the drive plate 28 and in this way provides for an additional rotary bearing of the decoupling element 32, specifically on the output member 26.
  • the window lifter can still be operated by hand immediately by bringing in the manual override key already mentioned with the vehicle tool kit and inserting it with its polygonal socket into the polygonal socket 88.
  • the key is rotated, for example in direction B
  • the partial hollow cylinder 92 accordingly also rotates in this direction (see FIG. 2).
  • the edge 94 lying further down in FIG. 2 comes to bear against the upper end 72 of the wrap spring 22.
  • the edge 94 pulls on the wrap spring 22 in its longitudinal direction, which causes the wrap spring 22 to lift off from the inner peripheral surface 76 and thus a loosening of the frictional engagement between wrap spring 22 and hollow cylinder element 18 results.
  • the window lifter can of course also be actuated in the opposite direction without any problems, in which case the partial hollow cylinder 92 with its upper edge 94 in FIG. 2 via the lower end 74 of the wrap spring 22 in FIG. 1 to the lower driver 78 presses.
  • the window can be quickly adjusted using the key, since the key acts directly on the output member 16 and the pinion 30 connected to it without large intermediate translation.
