Definitions

  • the invention relates to a tachograph with chip card recording units and with a transport arrangement for moving a chip card located in the read / write position into the removal position, the transport arrangement essentially comprising a servomotor which can be reversed in its direction of rotation, a reduction gear and a pushing device.
  • the smart cards assigned to the drivers are used for driver-related storage of at least personal working and rest times.
  • Driver and vehicle changes as well as traffic controls make it relatively often necessary to enter and remove chip cards in or from the tachograph used for data acquisition.
  • Such tachographs are generally designed as built-in devices with a flat, cuboid-shaped built-in housing.
  • the chip card receiving units and their drive means which cause a chip card located in the read / write position to be moved into the removal position, therefore have very little installation space available from the outset.
  • deformed, i.e., curved or corrugated chip cards during their use in particular if they have been manually inserted into the reading / writing position with a certain amount of force due to a deformation, require a considerable amount of force to put them back in to be able to transport the removal position. This power requirement must be applied and transmitted by the drive means, which requires a stable structure and thus sufficient installation space.
  • a chip card can be transported to the withdrawal position if necessary even with extreme power requirements and within a reasonable, relatively short waiting time.
  • the costs and the current consumption of the servomotor must be kept as low as possible, so that the reduction gear provided between the servomotor and the thrust device is of crucial importance in terms of its space requirement and efficiency.
  • DE-U 200 15 100.2 has disclosed a transport arrangement in connection with the displacement of chip cards into the removal position, in which a reduction gear provided between an actuator and a thrust device is designed as a two-stage worm gear, which apart from the expenditure on components and due to extreme nesting caused unfavorable installation conditions to result in relatively poor efficiency Has. Accordingly, a servomotor with a relatively high output is to be provided in this drive concept, so that even with increased friction of a chip card in the relevant receiving unit, sufficient torque is available for issuing the chip card in the intended time, which means a high degree of susceptibility to wear must be taken.
  • the object of the present invention was therefore to provide a reduction gear which is suitable for the generic use and which, with good suitability for series production with respect to manufacture and assembly of the gear components and low susceptibility to wear, offers a high degree of efficiency and can be realized with the smallest possible space requirement.
  • the reduction gear is at least partially designed as a planetary gear.
  • a preferred exemplary embodiment is characterized in that the transport arrangement is assigned a housing that guides at least the thrust device and supports the reduction gear, that a fixed toothing of the epicyclic gear is formed directly on the housing, that means are provided on the housing for non-rotatable flanging of the servomotor, and that the fixed toothing of the epicyclic gear is coaxial with the shaft of the servomotor on the housing.
  • the decisive advantage offered by the reduction gear according to the invention can be seen in particular in the fact that by providing an epicyclic gear, preferably a two-stage epicyclic gear, with the spur gears lying exclusively in parallel planes, the greatest possible efficiency is achieved, and thus for moving a chip card in the removal position, and in a relatively short time, a high actuating force is available for a given drive power.
  • the invention makes optimum use of the power of the servomotor provided, or it enables the use of a possibly cheaper servomotor of lower power and thus lower power consumption in view of the prior art for the removal position of the chip cards.
  • the latter is to be kept as low as possible anyway, since the tachograph's current consumption is limited by legal regulations for safety reasons.
  • FIG. 1 shows a top view of a generic transport arrangement with the cover removed
  • FIG. 2 shows a view of the inside of the lid
  • FIG. 3 shows a perspective view of the transport arrangement with the cover removed and an exploded view of the reduction gear.
  • the functional elements of the transport arrangement are mounted in a housing 1 which can be closed by means of a cover 2.
  • a channel 3 formed in the housing 1 is provided for the storage of a plurality of balls serving as flexible force conductors 4 and 5, one of which is designated 6 and 7, respectively.
  • 8 denotes a slider engaging in the channel 3, which is provided with a toothing 9 and on which a tongue (not visible in the drawings) is formed which engages in a slot 10 formed in the housing 1.
  • This design of a thrust device enables the transmission of large actuating forces with relatively little friction.
  • a pushing device with a is also conceivable Rack that meshes with two intersecting racks.
  • the toothing 9 of the slide 8 is in engagement with a spur toothing 11 of a pair of gearwheels 12 which is rotatably mounted on a hollow pin 13 formed on the housing 1.
  • hooks 23, 24, 25, 26, 27 and 28 are formed on the cover, which after the assembly of the functional elements when the cover 2 and the housing 1 are joined together, engage behind the housing 1 or its peripheral edge 29 and in this way the cover 2 on the housing 1.
  • the transport arrangement is designed as an independent assembly that can be handled independently of a device.
  • the actual attachment of the cover 2 to the housing 1 takes place indirectly, namely when attaching the transport arrangement, for example, to a circuit board of the tachograph, which is not shown as essential to the invention, in which the circuit board and through holes 30, 31, 32, 33 and 34 screws passed through the hollow pin 13, 14, 15, 16, 17 of the housing 1 are screwed to the pin 18, 19, 20, 21, 22 of the cover 2.
  • the rib 35 serves as a axial guide for a planet gear carrier 36 of the reduction gear, the rib 36 for centering the cover 2 and the housing 1 with respect to the shaft 37 in a direction reversible in its direction of rotation
  • Actuator 38 which is flanged to the housing and fastened by means of screws, one of which is visible in FIG. 3 and identified by 39.
  • a concentric to the rip pen 35, 36 formed on the cover 2 socket 40 serves a planet gear 41 of the reduction gear as a radial guide.
  • 44 and 45 represent end stops provided in the housing 1 and assigned to the slide 8.
  • 46 denotes one of two openings provided in the housing 1, through which light barrier elements fastened on the printed circuit board engage in the housing 1 and interact with the tongue of the slide 8.
  • the channel 3 and the guide grooves 42, 43 are designed on the end side in such a way that, after the cover 2 and the housing 1 have been joined together, there is in each case a slot-shaped opening 47 and 48 on the end side.
  • Push rods, not shown, which are preferably formed on carriages which are slidably mounted in the chip card mounting units and which carry the chip card, engage and stand after the mounting of the chip card receiving units and the transport arrangement on the printed circuit board through the openings 47, 48 in the channel 3 in active connection with the
  • the functional elements of the transport arrangement essentially these are the slide 8 and the force conductors 4, 5, are in a neutral position, from which either one or the other chip card can be shifted into their removal position and subsequently the slide 8 is controlled again in the neutral position.
  • individual freely movable balls 6, 7 existing power conductors 4, 5 and the slide 8 can be formed as a single component that can be produced by injection molding, each power conductor 4, 5 being made of a strand made of elastomeric material and attached to it by means of two-component injection molding technology spherical or barrel-shaped sliding bodies formed from a non-elastomeric material at a certain distance from one another.
  • the force flow for an actuating movement of the transport arrangement takes place starting from the servomotor 38 via a pinion 49 fastened to its shaft 37, which is provided with three planet gears 50, 51 and 52 of a first gear stage 53, one part of the lower gear. Settlement gear forming epicyclic gear is engaged.
  • the planet gears 50, 51, 52 are rotatably mounted on hollow axles formed on a first planet gear carrier 54 mounted on the shaft 37, the through openings of which are designated 55, 56 and 57, and mesh with the pinion 49 acting as a sun gear with a pinion in the housing 1 trained fixed teeth 58.
  • a pinion 59 is formed on the planet gear carrier 54, which meshes with three further planet gears 60, 61 and 62 of a second gear stage 63 of the epicyclic gear.
  • the planet gears 60, 61, 62 are also mounted on hollow axles which are formed on the already mentioned planet gear carrier 41 and whose through openings are denoted by 64, 65 and 66.
  • a gear 67 formed on the planet gear carrier 41 represents the gear connection between the epicyclic gear and the gear pair 12 in that the gear 67 engages with a spur toothing 68 of the gear pair 12.
  • Another embodiment of the reduction gear which requires particularly little installation space at a high transmission ratio, provides a "returning" epicyclic gear in which a toothed rack to be driven, for example the slide 8, engages in a gear formed on the planet gear carrier of the epicyclic gear.
  • the planet gear carrier is mounted on a hollow shaft, on which on the one hand a pinion serving as a sun wheel, the outer diameter of which is equal to or smaller than the outer diameter of the hollow shaft, is formed, on the other hand a gear wheel is formed, via which the drive of the epicyclic gear is based on a servomotor and possibly an upstream step transmission.
  • An external toothing assigned to the planet gears and an axis serving to support the hollow shaft can be formed directly on a housing component corresponding to the housing 1 or on a gear carrier insertable into a housing.
  • the external toothing of the epicyclic gearbox can, for example, also be formed as an internal toothing of a ring which is connected to the gearbox carrier via a suitable coupling, so that gearbox damage can be avoided if the reduction gearbox is overloaded.
