Definitions

  • the invention relates to a lifting platform for motor vehicles, consisting of at least one lifting column, which is a lifting element under the vehicle carries, which is vertically movable in the lifting column and its Lift movement is generated by an electric drive motor, in particular by means of a vertical spindle rotatably mounted in the lifting column, which is set in rotation by the drive motor and via a Mother with the vertically movable lifting element is engaged, the Drive motor is arranged entirely within the lifting column.
  • Such lifts are in FR-A 1 373 217 and in DE-A 2 311 845 described. They consist of two opposite columns, each one Column as a lifting element has two support arms, which can be telescopic and which are relocated under the vehicle standing between the pillars to position them under the intended jacking points of the vehicle.
  • the invention also relates to such lifts in which the Lifting elements designed as ramps or as a continuous platform are.
  • the drive is not hydraulic, but through an electric motor, this drive motor is on the side of the lifting columns flanged and stands on an intermediate gear with the above Spindle or other lifting device to generate the desired Lifting movement in connection.
  • the drive motor is stationary at the lower end of the Lifting column mounted, whereas it can be moved vertically in DE-A 2 311 845 is mounted on a threaded spindle and even the lifting movement performs together with the lifting element.
  • the present invention has for its object the known Lifts of the type described above to further improve, in particular to make the structure cheaper, but also more compact.
  • the drive motor has a vertical shaft axis is built into the lifting column and only without an intermediate gear by a drive belt with the spindle or an equivalent Drive element is connected. This gives a very compact Arrangement so that the motor fits into the usual lifting columns, without increasing their dimensions.
  • the motor shaft not as usual with V-belt pulleys for the V-belt drive to be equipped, but a sleeve with an outer axial groove profile or with circumferential grooves to attach to the motor shaft and one as a drive belt serrated belt with matching the groove profile Tooth pitch to use.
  • the groove profile is a further development of this idea not in the form of a separate sleeve, but through direct Material removal generated in the motor shaft itself. In these cases, it is particularly suitable as a drive belt a so-called poly-V belt.
  • Another advantageous embodiment of the invention is that there is no conventional drive motor but a case-less open motor is used. This gives further advantages in terms of Cost and dimensions.
  • the motor it is recommended himself, him flanged to the top cover of the column.
  • the free end of the motor shaft after directed above so that the belt connection to the spindle or the corresponding drive element after acceptance of an upper housing cover immediately accessible becomes.
  • FIG vertical lifting columns 1 and 2 With their base plate 1a and 2a are attached to the workshop floor.
  • Each Lifting column carries two horizontally swiveling and telescopically extendable support arms 3 and 4, the under the prescribed support points of the vehicle can be.
  • These arms are each guided vertically in its lifting column, in the embodiment by a lifting spindle 5, which is shown in FIG 2 and 3 is visible.
  • This lifting spindle can be rotated in stored their pillar and stands with an invisible Mother engaged, which in turn with the support arms 3 or 4 is connected.
  • the lift has the conventional structure. On the description the further details, especially the leadership the mother, not shown, and the whole Control is therefore dispensed with.
  • Figures 1 and 3 also show a cable bridge 11, in the control lines for switching on and off as well as for the synchronism of the lift. They are with the usual electrical or electronic Connected components that are also within the columns are arranged.
