Definitions

  • the invention relates to a tachograph with a drive for the time-dependent drive of chart disks serving as recording media with an actuating device which enables the chart disk driving means to be set to the current time.
  • the recordings are made in tachographs in such a way that they can be assigned to the current time. Accordingly, the chart drive means must on the one hand be adjustable to the current time, and on the other hand be designed for a time-correct recording on the chart drive means which allows only a very specific position of a chart with respect to the registration members.
  • the chart drive means is inevitable despite or precisely because of the high-precision quartz-controlled drives used in vehicles, because, for example, as a result of repair work on the vehicle, power failures can occur. Furthermore, apart from a summer / winter time changeover in long-distance transport, time zone violations must also be taken into account. Accordingly, the drive provided for the time drive of a tachograph may have to be set to the current time relatively frequently, that is to say that since a motorized adjustment is generally out of the question of cost, care must be taken to ensure that the relevant manual actuating device is one offers certain comfort, is therefore easy to operate and also larger Adjustment angle of the chart drive means can be set within a reasonable time.
  • a friction connection is usually provided between two gear wheels of the gear train, which are mounted on the same axis, between the motor of the drive and the diagram drive means, and a gear arm is assigned to an actuating element for one of the two gear wheels which are frictionally connected to one another.
  • the object of the invention was therefore to provide an actuator for a drive of the type described, that is to say with an extremely flat distribution of the gear elements, which offers a reliable function with little manufacturing effort.
  • the tachograph shown has a cuboid housing 1, on the front wall 2 of which a window cutout 3 is formed for a display 4 assigned to the front wall 2.
  • 5 denotes the front panel of a drawer 6 guided in the housing 1.
  • keys 7 and 8 and key 9, referred to as the menu key are assigned to the driver or the passenger to select at least the most important working time data.
  • the buttons 10 and 11 are used to page forward and backward in the respectively selected data records, the button 12 is provided for releasing the drawer 6.
  • FIG. 1 shows that a window 13 is provided in the panel 5 of the drawer 6, through which a pane 14 provided on the end face with a suitable marking is visible, which serves for the running display.
  • a diagnostic socket is secured by means of a seal labeled 15.
  • a seal labeled 15 For the sake of completeness, it should be mentioned that, as can also be seen from FIG. 2, the tachograph shown is designed as a built-in device and guide rails 16, 17 are assigned to the drawer 6, which is shown in its open position in FIG.
  • FIG. 2 It can also be seen from FIG. 2 that an opening 19 is formed in the bottom 18 (FIG. 4) of the drawer 6, which serves to facilitate the removal of an inserted chart 20.
  • the latter is integrally formed on a support 23 (FIG. 3) which is driven at the correct time by a drive 24 (FIG. 3) accommodated in the drawer 6.
  • a knurled disk 25, which protrudes laterally from the drawer 6, serves to set the support 23 and thus the centering and driving mandrel 22 to the current time.
  • a cover is designated, which is fastened in the drawer 6 parallel to the floor 18 and serves on the one hand as a registration document, on the other hand covers the drive 24 against dirt and what will be discussed again below, the gears of the drive gearbox mounted loosely on axles as a common axial securing means serves. Molded on the drawer 6 with Lugs 29 and 28 provided with guide slots 27 and 28 serve to fix the position of the drawer 6 in the closed state.
  • the diagram disk driving means 22, 23 are driven by a motor 31 or by a pinion 33 fastened to the shaft of the rotor 32 of the motor 31 via a gear connection comprising several gearwheel pairs.
  • the pinion 33 is in gear connection via the gear pairs 34/35, 36/37, 38/39, 40/41, 42/43 with a toothing 44 formed on the support 23.
  • a barrel 45 which is also in engagement with the toothing 44 and in which a trailing spring (not shown) is effective, is used in a manner known per se to compensate for play in the gear connection described above.
  • the gear 47 and the knurled disk 25 serving as an actuating element, as well as the gear 50 and the disc 14 serving as a running indicator is formed in one piece.
  • the axes of the gears 46 to 50, one of which is designated 51, are formed on the one arm 52 A of a two-armed lever 52.
  • the latter is rotatably mounted on an axle 53 which supports the gear pair 40/41 and is formed in the base 18 of the drawer and is under the action of a tension spring 54.
  • the gear connection provided for the running display can be used for setting the current time if the translations are designed accordingly.
  • the low overall height a of approximately 3 mm between the cover 26 and the bottom 18 of the drawer 6 in the area covered by the diagram disks is illustrated in particular, despite a certain space requirement of the lever 52. Outside the area covered by the diagram disks, a greater overall height can be used, so that the motor 31 and the first and second gear stages of the drive are accommodated there.
  • 57 denotes a limit stop of the drawer 6
  • 58 represents a guide slot of the drawer 6 corresponding to the guide slot 28.
  • 18 ribs 59 are formed on the bottom, which serve as a support for the lever 52.
  • the axially formed on the lever 52 and on the bottom 18, intended for the gears of the drive Xes are dimensioned such that the cover 26 serves as an axial securing means for all the gears, on the other hand the lever 52 is guided on the cover 26 by means of the end faces of the axles formed on it .
  • the cover 26 can also be designed angled such that it also covers the area of the motor 31.
  • FIG. 5 shows a measure for improving the coupling of the gear 38 mounted on the lever 52 into the toothing of the driving gear 37 after an adjustment process with the aim of avoiding disruptions in the power flow of the drive 24 when coupling.
  • the measure provides that on the teeth of the coupling gear 38 - a tooth is designated 60 - a surface 61 is formed axially parallel, in such a way that the surface 61, which is not mandatory as flat surface must be formed, starting from the tip diameter of the gear 38 to the non-driven flank 62 of the respective tooth 60 falls radially.
  • the dashed position of the teeth of the gear 38 represents the correct engagement of the gears 37 and 38, that is, the lever 52 is under the action of the tension spring 54 on the stop 55.
