Definitions

  • the invention relates to a tachograph with a housing, a cover pivotally associated with the housing and allowing access to the recording means, on the front side of which display elements can be observed at least for the speed measurements, a cover counter arranged independently of the cover and a path counter associated with the housing and with the housing by screws, which are sealed, releasably connectable cover, the front surface of which, lying essentially in the plane of the front surface of the cover, together with the front surface of the cover, forms the front surface of the tachograph and which has openings for the implementation of setting elements by means of which different driver activities take place assigned recording types can be selected manually.
  • Such a tachograph architecture is necessary if the demands made in connection with the redesign of dashboards and instrument consoles of commercial vehicles for as little assembly effort as possible, geometrically simple installation openings and more installation flexibility, i. H. that the height of the tachograph with respect to the dashboard level, for example with the dashboard level or the front surfaces of adjacent instruments, is to be designed so that it can be installed flush.
  • the tachograph is arranged in the driver's preferred line of sight, that is to say in the region of the steering wheel, that the pivoting radius of the cover is reduced, that the distance counter of the tachograph can be installed independently of the cover, which enables a substantial simplification of the counter drive and that, as has already been implemented in a known tachograph, as shown in DE-A-2411 515, the working time setting elements can be arranged aesthetically advantageously within the cross-section of the housing and also independently of the cover.
  • the width of the housing attachment or the cover forming the housing attachment should be made as small as possible, which means that, in particular in the case of a cylindrical housing, the relatively narrow, fixed circular arc section offers little choice for the additional arrangement of the working time adjustment buttons.
  • the latter also applies to the attachment of the cover to the housing.
  • the cover is screwed tightly from the interior of the tachograph and at least one of the screws in question is sealed, which represents a rather complex and cumbersome installation.
  • the aim was that, since the distance counter should be adjustable without any special assembly effort, it should ultimately also be interchangeable, the attachment of the cover, which of course must meet the structural requirements and must not interfere with the appearance of the tachograph, both easily accessible and can be carried out with simple means, as well as being inconspicuously sealable.
  • the solution to this problem provides that the cover is connected to the housing by means of hollow screws which can be actuated from the front, that the hollow screws are designed as bearings for the adjusting shafts transmitting the adjusting movements, that the adjusting knobs, which are not easily detachably assigned, cover the hollow screws largely invisibly and that the adjusting shafts are axially secured inside the housing.
  • a preferred embodiment of the invention is characterized in that the Adjustment shafts and the adjustment knobs each form a part and that slots are formed on a plate fastened and sealed inside the tachograph, which is accessible after opening the cover of the tachograph, and slots on the adjustment shafts are assigned to the slots.
  • the object of the invention thus satisfactorily solves the task combination, in particular it takes into account the design aspects dominating on the front of a tachograph and offers the advantage that it can be used in all possible housing shapes.
  • the subject of the invention is preferably applicable, for example, to tachographs in which at least one bearing element of the cover hinge is formed on the cover and thus high demands are made on the attachment of the cover.
  • a possible solution for a simple and inconspicuous sealing of the screw connection of the cover has been proposed.
  • the formation of the bearings of the adjusting shafts in such a way that they are adapted to an inclined position of the adjusting shafts with respect to the device axis is particularly advantageous for tachographs with cylindrical housings.
  • this design allows straight adjustment shafts to be passed into the interior of the tachograph housing, the arrangement of the adjustment shafts and thus the conicity of the bearings being very narrow due to the very narrow remaining between an inserted diagram disk serving as recording medium and the housing wall Gap is set.
  • a tachograph 2 installed in a dashboard 1, for example, flush with its front surface, is equipped in a known manner with a pivotably arranged cover 3, which can be locked with the housing 5 of the tachograph 2 by means of a lock 4, and a cover 6 which can be detachably connected to the housing 5 , the front surfaces of the tachograph 2 forming the front surfaces 7 and 8 of the cover 6 and cover 3 lying essentially in one plane.
  • Display means 10, 11 for the speed measurements and 12, 13, 14 for the display of the time can be observed through a window 9 provided in the cover 3, while a window 15 formed in the cover 6 enables a view of a distance counter arranged independently of the cover.
  • 16 and 17 designate buttons which serve to preselect recording types assigned to different driver activities, while 18 represents the front swivel gap or the front joint between the cover 3 and the cover 6.
  • FIG. 2 As shown in detail in the partial sectional view in FIG. 2 can be seen in more detail, two screws designed as hollow screws, of which in FIG. 2 a -19 - is shown, the attachment of the cover 6 to the housing 5, which, which is a particular advantage of the solution according to the invention, this attachment can be carried out with the interposition of a seal 20 on the front of the tachograph 2. Furthermore, from FIG. 2 the crucial idea of the solution according to the invention can be seen, namely that the adjusting shafts - one is designated by 21 - are passed through the banjo bolts 19 into the interior of the tachograph 2 and that the adjusting knobs 16 and 17 cover the banjo bolts 19 unobtrusively.
  • the banjo bolts 19 can also be countersunk in the cover 6 and at least one of these bolts can be secured, for example, by means of an annular seal. It is also conceivable to form an edge encompassing the hollow screws 19 on the adjusting knobs 16 and 17.
  • the preferred embodiment provides that the adjusting shafts 21 and the adjusting knobs 16 and 17 are each produced as one part and in the adjusting shafts 21 punctures - one is designated by 22 - are provided, which have suitable slots in a plate 23 which can be fastened and sealed in the tachograph 2 24 are assigned.
  • the attachment of the cover 6 is sealed in a particularly simple manner and with components that are required anyway from the outside in a manner that prevents access.
  • the arrow 25 is intended to symbolize mechanical connecting links via which an adjusting shaft 21 is operatively connected, for example, to a potentiometer, which is not essential to the invention, or to a working time registration element which can be pivoted into different registration tracks.
  • a diagram disk serving as a recording medium is designated.
  • the bores 27 in the hollow screws 19 are conical. In this way, the particularly simple design with straight adjusting shafts could be provided.
