Definitions

  • the invention relates to a tachograph for motor vehicles according to the preamble of claim 1.
  • the chart disks serving as recording media are known to be assigned to a hinged cover, in such a way that an inserted chart disk faces the viewer in all installation situations that are possible for the tachograph with the lid open.
  • a drive is arranged inside the cover, which drives a diagram disc holder accessible on the back of the cover, which serves as a registration document, and provided with a centering and driving mandrel at the correct time.
  • the architecture of the usual tachographs is further characterized in that the cross-sectional area transverse to the device axis is only slightly larger than the diameter of the diagram disks used. This minimization of the installation cross-section makes the device appear optically more advantageous for the viewer and allows the tachograph to be installed even in relatively narrow dashboards.
  • a tachograph version which does not require the cover to be swung open is known from US-A-3,281,854.
  • the recording medium entered through a slot in the upper wall of the housing is inserted into its registration position in a plane substantially parallel to the front wall.
  • Another solution is that the tachograph is divided into a display instrument which remains in the dashboard and a recording unit which is arranged in a suitable manner and is spatially separated from it and is suitably data-coupled.
  • the mounting of the registration unit in the driver's cab can vary widely.
  • the object of the present invention was therefore to create a tachograph which, as far as the handling of the recording media is concerned, does not require a spatial reorientation of the driver, offers better handling conditions, has the usual format-filling display and largely avoids the installation problems mentioned.
  • the tachograph architecture found does justice to all sub-areas of the task, in particular it offers simplified handling when changing the recording medium with the automatic feeding and dispensing. It is also advantageous that the immediate spatial assignment of the registration unit to a display instrument, which informs in a conventional manner about the current speed, the time of day and the distance traveled and thus corresponds to the character of the conventional tachograph, is retained.
  • the input slot arranged on the front and the overall architecture of the tachograph offer the option of installing it flush with the other front surfaces of a dashboard and using it as a component of a dashboard, so to speak. The exceptionally low installation depth that made this possible was achieved by consistently flat distribution and compression of the components, in particular the various drives and the electronic components of the tachograph.
  • FIGURE 1 shows a part of a dashboard or an instrument console 1 with a first section 2, in which various operating elements 3 and with a second section 4, in which display instruments are arranged.
  • a circular window 5 and 6 assigned to the display instruments for the display means of a tachometer 57 and the display means of a tachograph 6o, shielding aperture 7 is covered by a glass pane 8 assigned to the instruments.
  • the speed display means of the tachograph 6o are designated 9 and 10, the time display means 11, 12 and 13.
  • a cutout 19 is provided, which, when closed, of a pivotable flap 20, is flush with the front surface of the panel 14 is covered.
  • a button or a toggle 25 which extends through the panel 14 is expediently used the key 25 will have to be lockable.
  • the slits 21 and 22 are associated with a closing device arranged inside the tachograph. In the removal position, the diagram disks, as FIGURE 1 shows, face the operator in a convenient manner.
  • FIGURES 2 and 3 show the tachograph 6o according to the invention as an autonomous device with a housing 26 and a front pane 27 covering the display means 9, 10, 11, 12, 13 arranged in a window cutout 58 of the front wall 59, which in this form also serves as a dashboard segment or dashboard module can be used.
  • 28 and 29 denote light-emitting diodes, with which the respective state "occupied” or “free” of the diagram disk guide shafts 3o and 31 assigned to the slots 21 and 22 can be indicated.
  • the guide shafts 3o and 31 are each formed by plates 32, 33 and 34, 35, which also serve as mounting plates, for example by the speed measuring device 36, a drive 37 for the time display, the not shown registration elements, which are mounted on swivel arms 38 and 39 , centering and driving means for the diagram disks and their registration drives, which are not specified in detail.
  • the diagram disks are transported to and from their registration positions by means of transport roller pairs 4o, 41 and 42, 43 which engage in the guide shafts 3o and 31 and are connected to one another in terms of gears via gearwheels 44 and 45 and, starting from a motor 46, via a gearwheel gear 47, 48 are driven.
  • the staggered arrangement of the pairs of transport rollers 4o, 41 and 42, 43 serves on the one hand to minimize the spacing of the guide shafts from one another, and on the other hand to create the same insertion length possible for both recording media.
  • the variant of the tachograph 6o according to the invention shown in FIG. 4 is equipped with an LC display, with which a digital display 49 of the clockwork and 5o of the distance counter and a quasi-analogue display 51 of the speed measuring device take place.
  • the input of the working time states is implemented in the form of keys 52, to which light-emitting diodes can be assigned, for example.
  • FIGURE 5 shows in a front-flush installation (level A) of a conventional tachograph and the tachograph 6o according to the invention that the space between levels B and C, i. H. the required installation and the required operating space of the conventional tachograph when the cover is open is considerably larger than the space between levels D and E, which corresponds to the tachograph 6o according to the invention.
  • dimension a indicates the same window section for the display means.
