Definitions

  • the invention relates to the arrangement of a distance counter in a tachograph, the distance counter being mounted as a functional unit with a counter frame, in which the numbered rollers of the distance counter, the ten-turn actuators assigned to the numbered rollers and drive means for the one-numbered roller are arranged on suitable axes. and the tachograph is assembled from a plurality of housing components, one of which at least partially forms the front surface of the tachograph.
  • the count values of a distance counter should be readable on the front of the measuring device in question, which means that the numbered roller set of a mechanical distance counter must be arranged directly behind the front surface of the measuring device.
  • the distance counter is either in the hinged housing part, hereinafter referred to as the cover, or in an essentially cover-flush attachment of the stationary housing part of the tachograph.
  • the frame of the distance counter is screwed to a first housing component of either the cover or the stationary housing part of the tachograph and the screw connection because of special importance of the distance counter secured in a suitable manner.
  • the required, tamper-proof, front cover forms a further housing component which can be connected to the first housing component, in which, if not an additional part has to be used for this purpose, because what can be the case with an arrangement in the cover, a frame for the further housing component a the counter cross-front window is provided, the count value ausblendende counter f is formed Enster.
  • a functionally preassembled distance counter is described, for example, in DE-A-1 250 665.
  • the distance counter is attached to the rear of the hinged cover of the tachograph in such a way that the bottom of the counter frame forms part of the cover base.
  • Another solution is shown in DE-A-2 237 087. In this solution, the distance counter is largely completed at the bottom of the cover on which the frame walls are formed, whereby only the set of dial rollers can be used as an assembly in the frame walls and the cover subsequently must be composed of several parts.
  • the aim of the present invention was therefore to find an arrangement of the distance counter in a tachograph, with which additional assembly effort for aligning the counter window is avoided and which is suitable for mechanical assembly with largely minimized component requirements.
  • a receptacle that at least partially corresponds to the contours of the tachograph is provided on a first housing component of the tachograph, that a counter window that hides a section of the numerical roller set of the tachograph is formed on the second housing component that at least partially forms the front surface of the tachograph and that the distance counter inserted in the first housing component is held indirectly by the second housing component fastened to the first housing component.
  • a preferred embodiment of the solution according to the invention is characterized in that the receptacle is designed in the form of a pocket, that a two-armed leaf spring can also be latchedly connected to the counter frame and that one arm of the leaf spring acts in the axial direction on the set of digits while the other arm , when the distance counter is inserted into the first housing component, is supported on the bottom of the pocket.
  • the preferred exemplary embodiment provides a combination of aligning means formed on the second housing component, namely on the one hand a prismatic depression, on the other hand a notch and on the counter frame formed straightening elements in the form of a cutting edge on the one hand and a prismatic tip on the other hand. r.
  • the arrangement according to the invention offers, apart from the fact that the object is achieved in a satisfactory manner, is to be seen in the fact that for the fastening of the distance counter, no fastening elements exclusively associated with the distance counter and associated assembly costs are required, ie at the Monta ge, the distance counter is only supplied to the first housing component and is released or inserted into the pocket via the receptacle, which is preferably designed as a pocket. Furthermore, with the arrangement according to the invention, an exact and automatic alignment of the numerical roller set and counter window is achieved, not least because of the special design of the leaf spring associated with the distance counter and self-lockingly held on the counter frame by a suitable latching connection. It is also advantageous to design the pocket provided for receiving and loosely holding the distance counter, which at the same time offers the necessary security against intervention.
  • tachograph 1 shows a tachograph 1, which is flush-mounted in a dashboard 2 and whose front surfaces 3 and 4 are on the one hand on the hinged, but unspecified cover of the tachograph 1, on the other hand on an approach of the also not designated stationary housing part of the tachograph 1 forming and detachably connectable to the stationary housing part cover 5 are located and thus lie essentially in the plane of the dashboard 2.
  • the cover of the tachograph 1 can be locked to the stationary housing part by means of a lock 6 and has a glass pane, not designated in any more detail, inserted into a window cutout 7, through which display means for speed 8, 9 and time 10, 11, 12 are visible.
  • Numeral 13 denotes a section provided in the cover 5, serving as a counter window, while 14 and 15 represent setting buttons which serve to preselect the type of working time registration.
  • the distance counter the number roller set 16 of which is visible through the counter window 13 is assigned to the stationary housing part of the tachograph 1.
  • the front joint or the swivel gap between the cover and the cover 5 is designated 17 for completeness.
  • FIGS. 2 and 3 on an annular housing element 18 of the fixed housing part of the tachograph 1, apart from a mounting base 19, on the one hand two threaded attachments 20 and 21 serving to fasten the cover 5, on the other hand one of the receptacles and loose Bracket of the distance counter 22 formed during its assembly pocket 23.
  • the cover 5 is fastened by means of two banjo bolts 24 and 25, which additionally serve as bearings for the adjusting shafts connected to the adjusting knobs 14 and 15, one of which - 26 - is shown.
  • a glass pane 27 completing the counter window is inserted in the cutout 13 and that 28 represents a sealing body inserted into a suitable circumferential groove located in the housing component 18.
  • the distance counter 22 known per se is composed essentially of the set of numerical rollers 16 and a ten-shift drive set 29 associated therewith, which or their individual elements, namely the numerical rollers and the ten-shift drives, are each rotatably mounted on axes 31, 32 arranged in a counter frame 30 .
  • the counter frame 30, as shown is made of light-conducting material.
  • An elongated hole 33 is assigned to the ten-switch drive shaft 32 in at least one cheek of the counter frame 30, which enables the ten-switch drives 29 to pivot out of their engagement with the dial rollers and thus to align the dial rollers 16.
  • the necessary elastic support of the ten-shift drive shaft 32 is provided by a spring arm 35 which is formed in one piece on a centering bush 34 assigned to the number roller shaft 31.
  • the distance counter 22 or its one-digit roller 16/1 is driven by a helical gear 36 formed on the one-digit roller 16/1, which is in engagement with a further helical gear 39 formed on a drive shaft 38 mounted in a bearing housing 37 formed on the counter frame 30.
  • the shaft 38 projects through an opening 40 in the pocket 23 into the interior of the tachograph 1 and is in gear connection with, for example, a stepping motor via coupling means 41 formed thereon and further gear elements (not shown).
  • a cutting edge 43 carried by a bracket 42 is also formed on the counter frame 30 of the distance counter 22. Aligned in the counter axis direction with a prismatic tip 44 which is also formed on the counter frame 30. Corresponding to these straightening elements, a notch 45 and a prismatic depression 46 are provided on the cover 5.
  • a leaf spring 47 is held on the counter frame 30, one arm 48 of which acts on the dial roller axis 31 or on the centering bushing 34 locked with the dial roller axis 31 and thus ensures the axial play compensation in the dial roller set 16, while the other arm 49, which is on the one hand on the counter frame 30, on the other hand, basically supports the pocket 23, causes a resilient mounting of the distance counter 22 between the housing component 18 and the cover 5 or the coupling force required between the alignment means 45, 46 and the alignment elements 43, 44.
  • Hooks 50 and 51 which are bent out of the leaf spring 47, and a bent tab 52 are used by the hooks under the action of the arm 48, which is supported on the dial roller axis 31, through suitable, unspecified openings in the counter frame 30, to engage behind the relevant frame wall, in other words, the self-locking mounting of the leaf spring 47 on the counter frame 30.
  • 53 denotes a first, cup-shaped housing component of the cover and 54 another housing component, which can be latched to the housing component 53 of the cover, namely a front frame.
  • the presentation of details and assemblies within the cover has been dispensed with because the cover is not essential to the invention in any case with the selected tachograph type with the cover hinge lying inside, so to speak. It is crucial, however, that in the preferred embodiment shown, the cover, when it is completed, by a specially designed cylinder-shell mounting, which fulfills both the sealing requirements and a flat design of the front surfaces of the cover and the cover 3 and 4 enables and is characterized by a small space requirement, is caught on the cover 5.
  • two bearing shells 55, 56 are formed on the housing component 53 of the cover, which is centered on the housing component 18 with a cutting-notch connection 60/61, which encompass a continuous bearing shell 57 molded onto the cover 5, while on the a cylindrical lip 58 corresponding to the inside diameter of the bearing shell 57 is formed with the housing component 53 of the cover.
  • the housing component 53 of the cover is expediently first inserted into the housing component 18 presented.
  • the distance counter 22 which is completely pre-assembled together with the leaf spring 47, is inserted into the pocket 23 of the housing component 18, with projections and webs formed by suitable contours on the housing component 18 and in a suitable manner on the counter frame 30 - one being designated by 59 - a loose holder and a rough alignment of the distance counter 22 takes place.
  • the cover 5 is put on, aligned with the position of the bearing shells 55 and 56 formed on the housing component of the cover 53, and fastened to the housing component 18 by means of the banjo bolts 24 and 25, under the action of the leaf spring 47 or its arm 49 and by a
  • the aligning means and aligning elements 43, 45 and 44, 46 engage in automatic fine adjustment of the digit roller set 16 and counter window 13.
  • the front frame 54 is snapped onto the housing component of the cover 53 and, by the Lip 58 engages in the bearing shell 57, the storage of the cover on the cover 5 is completed.
  • the arrangement of the distance counter described in the stationary housing part of a tachograph is also possible in the same way in the hinged cover of a tachograph type, in which the cover surface forms the entire front surface of the tachograph.
  • Suitable holding means for the distance counter are then to be formed in the preferably pot-shaped base part of the cover, and the front frame, which is preferably snapped onto the base part of the cover, is additionally to be provided with a counter window and corresponding alignment means.
