Definitions

  • the invention relates to a recording device for route recorders, generally called tachographs, and in particular a device that can come into action automatically as soon as the vehicle is in motion.
  • route recorders to record data intervening during the use of a vehicle, such as the distance traveled, the speed performed, the travel time. These data relate to use in driving, to one or two drivers, and are reported by writing means which make it possible to obtain a recording trace on a chart-holding disc (or two discs in a two-driver variant) driven in accordance with real time by an organ such as a watch.
  • Such devices include writing means for obtaining a recording trace on a diagram-carrying disc.
  • writing devices are used which operate both during the running of the vehicle and for the recording of auxiliary work, such as loading and unloading, repairs on the vehicle, waiting times and the like, while the vehicle is at the stop.
  • These working time recording devices provided that they also write thick line diagrams, are most often driven by an electric oscillation generator, and are generally mounted on axes arranged inside the housing. the route recorder or on a mounting plate that can be installed inside the route recorder.
  • a special motor is therefore generally provided to control the writing means when the vehicle is stationary, so as to have a thickened line on the diagram-bearing disc, since the conventional means of obtaining such a line by a back and forth movement of the writing stylus controlled by the odometric mechanical chain is obviously no longer usable.
  • the activity carried out is identified on the diagram-carrying disc by a “time-driver” plot, the thickening of which is obtained. by the movement of the stylus back and forth, movement which is controlled by the odometric mechanical chain.
  • this command is not automatic: the driver must press a button on the front of the unit. This maneuver is compulsory: in the event of forgetting, the driver would be in violation of the regulations and the counting on the ground would be distorted, hence the tedious aspect of such a maneuver when it is repeated several times.
  • An object of the invention is to provide a registration device which can come into action automatically as soon as the vehicle is running, and which is of simple design while having high reliability.
  • Another object of the invention is to obtain a recording of the “time-driver of easy reading.
  • Another object of the invention is that the proposed registration device is easily adaptable for a two-driver application.
  • a final object of the invention is that the device is compatible with a so-called "intrinsically safe” approval, relating to the transport of dangerous materials by road vehicles.
  • the invention relates to a recording device for route recorders, capable of entering into action automatically as soon as the vehicle is in motion, comprising writing means for obtaining a recording trace on a chart-holding disc and a multi-position guide cam cooperating with the listing means so as to obtain a layout thus accounting for the different types of use of the vehicle, characterized in that it comprises additional guide means which can replace the guide cam at several positions, and in any of said positions, and actuation means, controlled by the vehicle speed chain, automatically performing said substitution as soon as the vehicle is in motion so that the writing means produce a trace corresponding to a driving position.
  • the additional guide means essentially consist of an additional cam coaxial with the guide cam with several positions, the internal radius of which makes it possible to cover said cam in several positions to replace it automatically in the position of conduct.
  • the additional cam includes a support ring which can slide on the cam pin in several positions, and a lateral bar whose cross section dirty has the shape of a meniscus, said bar automatically cooperating with the writing means in the driving position to obtain a trace of thickness greater than that of the traces obtained with the cam in several positions; the cam with several positions and the additional cam are advantageously integral in rotation, and subjected to the action of a spring tending to move them away from one another.
  • the actuation means allowing the automatic substitution in the driving position essentially comprise a drum whose rotation is controlled by the speed chain of the vehicle and a lever cooperating at one end with said drum and by the other end with the additional guidance means so that this substitution occurs as soon as the speed of the vehicle crosses a predetermined threshold; for example, the drum has a circular track against which the associated end of the lever is supported, said track being interrupted by a notch with an inclined ramp which can cooperate with said end when the vehicle speed drops from zero to the predetermined speed threshold, and said drum further carries the axis of the tachometer indicator needle.
  • the device then advantageously includes means allowing an abrupt automatic substitution in the driving position as soon as a very low speed threshold is reached, for example 0.1 km / h, for example by a servo setting setting in motion over a short angular range. the vehicle speed chain as soon as the speed threshold is crossed, said angular range being sufficient for automatic substitution to be carried out.
  • the writing, guiding and actuating means are split for recording on two diagram-carrying discs, so as to distinguish the use of the vehicle by one of two drivers, the speed chain of the vehicle controlling the actuation means for automatic substitution in any one of the two kinematic chains; when a control drum is provided as above, said drum is preferably common to the two kinematic chains, the splitting occurring for the lever, the guide means and the writing means.
  • the illustrated recording device comprises writing means 1 for obtaining a recording trace on a diagram-carrying disc 2 driven in accordance with real time by a watch 3, and control means 4 acting directly on the means subscribers 1 for a route giving an account of the different types of use of the vehicle.
  • the control means 4 are here in direct engagement with the drive motor of the watch 3, and there is provided a guide cam 5 with several positions, cooperating with the writing means 1 so as to obtain a layout whose thickness corresponds to each of said positions. Direct movement is thus achieved by engaging a pinion 6 mounted on an output shaft 7 of the watch drive motor 3, on a pinion 8 forming the start of the kinematic chain of the control means 4, this chain continuing with sprockets 9, 10, to drive a pin 11 on which the cam 5 slides freely, the assembly being held by fixed elements 12, 13 secured to the housing of the device.
  • the roller 14 of the stylus holder 15 bears against the cam 5, on one of its tracks 16, 16 ', 16 "(here 16"), the choice being made by a manual control button (not shown) accessible from the front of the housing and acting on a member 17 serving as a pusher for said cam.
  • the choice of tracks determines the layout mode with its thickness.
  • the track 16 is circular and corresponds to a rest position, the recording on the diagram-carrying disc 2 resulting in a simple thin circular line.
  • the non-circular tracks 16 'and 16 "correspond to two working positions when stationary, for example loading / unloading and repairing respectively.
  • the device further comprises additional guide means 18 which can replace the cam 5, and this in any of the positions thereof, as well as actuation means 19, controlled by the vehicle speed chain, automatically performing said substitution as soon as the vehicle is in motion so that the writing means 1 produce a trace corresponding to a driving position.
  • the additional guide means 18 can be produced in several ways, the important thing being that they replace the cam 5 in the driving position.
  • the illustrated embodiment consists of a cam 18, coaxial with the cam 5 in several positions.
  • the cam 18 comprises a support ring 20 which can slide on the pin 11, and a lateral bar 21 whose cross section has the shape of a meniscus; it is this lateral bar which "covers" the cam 5 in a way when it acts as a support for the roller 14.
  • the cams 5 and 18 are integral in rotation. This joining is illustrated by the passage of the end 22 of the cam 5 in a lateral orifice 23.
  • the pin 11, the movement of which is controlled from the clockwork movement 3, carries a pin 24 engaging in a longitudinal groove 25 passing through the support ring, so that the cams 5 and 18 subjected to the action of a spring 26 tending to move them away from each other, rotate continuously, regardless of their relative axial position.
  • the tracks 16 'and 16 "have as minimum radius the radius of the circular track 16, so that the meniscus of the bar 21 has a corresponding substantially circular internal curvature, the external curvature being chosen, in shape and in maximum radius, depending on the method of registration and the thickness of the path chosen.
  • the actuating means 19 are engaged on the speed chain of the vehicle: the block 27 shows diagrammatically the conventional speed gain, with an output pinion 28 which is used, in known manner, to control the tachometer needle 29 and the means 30 speed markers (illustrated schematically).
  • a drum 31, the rotation of which is controlled by the pinion 28, by means of an auxiliary pinion 32, has a circular track interrupted by an inclined ramp notch 33.
  • a lever 34, here articulated, cooperates at one end with the inclined ramp notch 33, and by its other end with a washer 35 bearing against the cam 18.
  • the other end of the lever pushes the cam 18 towards the cam 5, against the action of the spring 26. Due to the coupling of the two cams, the bar 21 is always well positioned radially, to avoid a stop against the roller 14 which would prevent the cam 18 from covering the cam 5 in the driving position. It should be noted that this does not depend on that of the tracks of the cam 5 against which the roller 14 rests when one passes into the driving position.
  • a very low speed threshold 0.1 km / h for example
  • a housing (not shown) in which the recording means 1, the control means 4, the cams 5 and 18 and the actuating means 19 are arranged, while an articulated cover (not shown) supports the watch 3 and the diagram-carrying disc 2.
  • the direct movement movement on the watch, to control the cam 5 and the writing means 1, is thus carried out as soon as the articulated cover is closed, from which the pinion 6 towards the housing; this makes it possible to have a thickened trace on the diagram-carrying disc when the vehicle is stationary, this trace having a thickness specific to each position of the cam 5, therefore to each type of use for the driver.
  • the cam 18 automatically replaces the cam 5 by covering the latter, and a plot having an even different thickness is obtained, so that the reading of the diagram-carrying disc is very easy.
  • the second chain uses on the one hand, for the cams and the writing means which are specific to it, a direct power take-off on the watch (with the pinion 9 for example), and on the other hand, for its own operating lever, a power take-off on the vehicle's speed chain with a common control drum.
