Definitions

  • the invention relates to a lifting platform for motor vehicles, consisting of at least one lifting column, the one that Vehicle supporting lifting element that carries vertically is movably mounted in the lifting column and its lifting movement generated by an electric drive motor is, in particular by means of a vertical, in the Pillar-mounted spindle, driven by the drive motor is rotated and with a nut the vertically movable lifting element is engaged.
  • Such lifts are in numerous embodiments known. They usually consist of two opposing ones Pillars, each pillar as a lifting element two has telescopic swivel name that under the vehicle swung between the columns and under the intended jacking points of the vehicle be positioned.
  • the invention also relates to such lifts, where the lifting elements as ramps or are designed as a continuous platform.
  • the drive is not hydraulic but is done by an electric motor this drive motor is flanged to the side of the lifting columns and stands over an intermediate gear with the mentioned spindle or another lifting device for Generation of the desired lifting movement in connection.
  • the present invention is based on the object the known lifts of the type described above continue to improve, in particular to build more cost-effectively, but also to make it more compact.
  • the motor shaft is not used as usual To equip V-belt pulleys for the V-belt drive, 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 to place it at the top of the column, especially 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.
