Definitions

  • the invention relates to a motor vehicle jack with connectable electric motor drive device according to claim 1.
  • Motor vehicle jack with on their drive shaft attachable electric motor drive device are known from DE 16 03 765 A1 and DE 78 17 326 U1.
  • the operation of a Motor vehicle jack with a coupled electric motor drive device especially regarding the physical Burden on the operator, can be simplified.
  • an electric motor drive device is advantageous an existing one, e.g. by EP 0 133 527 B2 known motor vehicle window drive provided, the Gearbox output shaft with the drive shaft of a jack, especially one with the same plug-in coupling also standard car jack that can be driven by a hand crank, intended.
  • Pillar jack 3 in its basic structure e.g. is known from DE 16 03 765 A1.
  • a lifting column becomes a spindle in a manner not described here via a bevel gear 3.3 from a drive shaft 3.2 in the one or the other direction of rotation, causing a Spindle carriage with a support 3.4 for the one to be lifted or motor vehicle to be lowered up and down along the spindle is moved.
  • the electric motor drive device is not on the application limited to a column jack but can be in equivalent also for a parallelogram jack are used, e.g. known from DE 78 17 326 U1 is.
  • the spindle of the jack 3 is an electric motor drive device 1; 2 is provided which consists of a structural unit of an electric motor 1 and one flanged to it Gear 2 exists. It is advantageous for such an electric motor drive device well known, already in series production Motor vehicle window lifter drive provided, such as e.g. out 1 of EP 0 133 527 B1 can be removed.
  • the electric motor drive device 1; 2 For torque transmission from the electric motor drive device 1; 2 on the spindle of the jack 3 is the electric motor drive device 1; 2 by an axial coupling plug-in movement in direction F with its output shaft 2.1 in a coupling 3.1 with the drive shaft 3.2 of the jack 3 can be plugged in in the sense of a positive rotary drive; to positive rotational driving is expediently a toothed rack driving provided such that e.g. the output shaft 2.1 of the electric motor drive device 1; 2 with a External teeth and the sleeve-shaped coupling 3.1 with a corresponding internal toothing is provided.
  • the clutch 3.1 designed as a universal coupling such that, if necessary instead of the output shaft 2.1 of the electric motor drive device 1; 2 also a hand crank with corresponding external teeth usable and so in emergency operation of the jack can also be operated manually using a hand crank.
  • jack is for positive locking Fixing the couplable electric motor drive device 1; 2 particularly in terms of manufacturing and assembly technology simply a separate car-side fixation aid 4 provided, which - as in particular from the Exploded view according to FIG 1 and the finished representation shown in FIG 4 - with the lifting column of the jack forks around both sides 4.2 by pressing or clipping can be attached to the jack 3.
  • the fixing aid 4 is with a protruding fixing cam 4.1 provided in the final assembly position in the sense a latch in a fixing recess 5.1 of a counter-fixing aid 5 intervenes in manufacturing and assembly technology particularly simple sleeve-shaped from the free End of the electric motor 1 pushed axially onto it is pressed.
  • the final securing between the fixing cam 4.1 the fixing sleeve 4 on the one hand and the fixing recess 5.1 the counter fixation aid 5 on the other hand is done by a fixing pin 6, which is in a Pin hole 5.2 of the counter-fixing aid 5 inserted and thereby through a pin hole 4.11 in the fixation recess 5.1 inserted fixation pin 4.1 inserted is.
  • the fixing aid 4 has an adjustment arm 4.3 in Direction of the lifting column of the jack 3, which by means of a Adjustment arm fixation protruding against the lifting column 4.31 with an accurate adjustment arm counter fixation 3.5 Lifting column - e.g. by clipping - can be brought into engagement.
  • the electric motor drive device 1; 2 via a connecting line 7 and a connector 7.1 from the vehicle electrical system, in particular from an already installed cigar lighter socket, fed.
  • a direction of rotation switch provided here as a rocker switch 8 is the current direction of the feed current for the preferably designed as a commutator motor reversible and accordingly the lifting direction of the trailer 3.4 of the jack 3 changeable.
