Definitions

  • the invention relates to an adjustment drive with a geared motor with a position that can be fixed by positive self-locking according to claim 1; an adjustment drive with the features a) to c) of claim 1 is known from DE-A1-29 11 024.
  • a pawl is pivotably mounted in the driver under spring pressure in such a way that it is in the motor drive side as well as in the drive side drive
  • the sprocket engages, whereby during motor operation in one direction of rotation (lifting) the pawl in the form of a ratchet slides over the teeth of the sprocket without inhibition and in the other direction of rotation (lowering) it is released against the spring pressure by a stop cam or in the case of an output side Drive is pressed in this direction of rotation (lowering) by the spring pressure in the sense of a positive self-locking in the ring gear.
  • a tangential play between the driver on the one hand and the worm wheel on the other hand is only possible within the framework of the elastic flexibility of the damper element interposed in the driver between the worm wheel and the driver.
  • the grinding resistance between the slip ring and the gear housing is advantageously chosen such that, on the one hand, when driving with a motor drive, there is as little resistance as possible in the one or the other direction, but with drive-side drive in the other direction of rotation there is sufficient impact resistance for pivoting the pawl out of it Sprocket non-contact rest position is guaranteed in its positive self-locking locking to the sprocket;
  • Such a bias for the slip ring is achieved in a particularly simple manner in that it rests against the gear housing from a material and / or shape residual stress Plastic ring is formed, wherein preferably the first free-link cams or second pawl cams are integrally molded onto the plastic ring.
  • a worm wheel 2 is rotatably mounted about a gear axis 1.2, the external teeth 2.3 of which mesh with a worm shaft 7, which is part of a rotor shaft of an extended commutator motor, not shown here, which is flanged to the gear housing 1 is trained.
  • the gear housing 1 is closed on its open side by a gear housing cover 1.1.
  • the worm wheel 2 is interposed by an attenuator 5 in a tangentially elastic rotary driving connection with a driver 3, also rotatably mounted on the gear axis 1.2, with a drive shaft inner pinion 3.3, which is led out on the output side through the worm wheel, which is tangentially movable on the outside and through a bore in the gear cover 1.1.
  • the gear housing cover 1.1 is sealed with the interposition of sealing rings 1.11 and 1.12 both against the pot edge of the gear housing 1 and against the outer circumference of the output shaft inner pinion 3.3.
  • the worm wheel 2 which is preferably injection molded from plastic, engages with corresponding radial grooves of a damping member 5 integrally molded over its circumference in corresponding radial grooves of an attenuator 5.
  • the driver engages with tangential driving elongated holes 5.1 with integral radial overhanging cams 3.1 such that the tangential length of the elongated holes 5.1 results in tangential play in the rotational driving is possible between the worm wheel 2 on the one hand and the driver on the other hand beyond the tangential play of the elastic compliance of the damping member 5.
  • a plastic slip ring 4 is mounted axially below the ring gear 1.3 in the sense of a minimum grinding pressure, that it rests with contact shoulders 4.3 on the grinding surface of the gear housing 1 and is pressed radially against the grinding surface in the gear housing 1 by prestressing the spring bars 4.4 connecting the contact shoulders 4.3 when the slip ring 4 is pushed into the gear housing 1.
  • the slip ring 4 each has a first free-latch cam 4.1 - seen in the direction of rotation n 1 - in front of the pawl 6 and in the vicinity of its contact shoulder 4.3 and a second pawl cam 4.2 behind the pawl 6. Viewed in the direction of rotation n 1, an axial stop cam 2.2 of the worm wheel 2 also projects into the axial region of the first free-latch cam 4.1.
  • the worm wheel 2 In motor operation for lifting the window pane, the worm wheel 2 is driven via the worm shaft 7 in one direction of rotation n 1.
  • the worm wheel 2 is in contact with the damping member 5 and then after tangential stop of the driving cams 3.1 of the driver 3 via its driving webs 2.1 engaging positively in corresponding grooves of the damping member 5 one or the other end face of the elongated holes 5.1 also in elastically damped rotary driving with the driver 3.
  • the driver 3 is subsequently rotated in one direction of rotation n 1
  • the pawl 6 comes into contact with the first free-latch cam 4.1 so that when fully released from the Gear ring 1.3 of the slip ring 4 is also moved over the first free-click cam 4.1.
  • the attenuator 5 is again carried tangentially by the worm wheel 2 via the driving webs 2.1.
  • the driving cams 3.1 of the driver 3 strike the end face of the elongated holes 5.1 and thus set the driver 3 in motion in a cushioned manner
  • the stop cams 2.2 formed axially on the worm wheel 2 come into contact with the first free-click cams 4.1 of the Slip ring 4 that this is initially moved by a small tangential angle in the other direction of rotation n2 and thereby ensures that the pawl 6 is released.
  • the driver 3 executes a relative movement to the worm wheel 2 in such a way that, before tangential entrainment of the worm wheel 2, the free end of the pawl 6 pivoted free against the second pawl cam 4.2 of the slip ring 4 comes to rest. Due to the grinding resistance between the slip ring 4 and the gear housing 1 which receives this under slight radial pressure, the pawl 6 is brought into engagement with the ring gear 1.3 when the driver 3 moves in the other direction of rotation n 2.
  • the pawl 6 As soon as the free end of the pawl 6 comes into contact with the ring gear 1.3, the pawl 6 is self-lockingly fixed in its engagement position to the ring gear 1.3 with still further tangential movement of the driver 3 in the other direction of rotation n 2 and thus the pawl cam 4.2 relieved.
  • the grinding resistance between the slip ring 4 and the gear housing 1 is selected such that, on the one hand, when driving the motor drive in one or the other direction of rotation n 1 or n 2, as resistance-free as possible, but with the drive-side drive in the other direction of rotation n 2, there is sufficient impact resistance for pivoting the Pawl 6 is guaranteed in its positive self-locking latching in the ring gear 1.3.
  • the worm wheel or the driver or the pawls are designed in the sense of an axial plug-in assembly technique.
