Description

_ 1 9_

  The invention relates to a registration device

  for road recorders, generally referred to as tachographs

  graphs, and in particular a device that can enter into

  action automatically as soon as the vehicle is running.

  It is known to use road recorders to record data intervening during the use of a vehicle, such as the distance traveled,

  the speed made, the time of the road. These data

  identify use in driving, with one or two

  fers, and are carried forward by listing means which make it possible to obtain a recording plot on a

  diagram disk (or two disks alternatively

  drivers) trained in accordance with real time by a

organ such as a watch.

  Such devices comprise registering means

  to obtain a recording plot on a portediagram disk. Thus, it is possible to use listing devices that operate both during vehicle operation and for auxiliary work recording, such as loading and unloading, vehicle repetitions, waiting times and the like, while the vehicle is in operation. shutdown. These time-stamping devices, insofar as they also include

  thick line diagrams are most often

  trailed by an oscillating electrical generator, and are generally mounted on axes arranged inside the housing of the road recorder or on a mounting plate that can be set up inside the

the road recorder.

  It is therefore generally provided a special motor to control the listing means when the vehicle is stopped, so as to have a thickened line on the disk-diagram because the conventional means for obtaining --2- such a feature by a movement back and forth of the stylus stylus controlled by the mechanical odometry cat is obviously no longer usable. Without insisting on the disadvantages of such a special motor, it is important to note that for such devices, the conducting activity is marked on the chart disc by a "heat stroke" plot, the thickening of which is obtained by the

  back and forth movement of the stylet, a movement that is com-

  mandated by the mechanical odometric chain. This order

  However, it is not automatic: the driver must

  a button on the front of the box. This maneuver is obligatory: in case of forgetfulness, the driver would be in violation with the regulation and the stripping on the ground would be distorted, hence the tedious aspect of such

  maneuver when repeated several times.

  Other known devices use the position-

  of a mechanical organ from the odomé chain.

  for the conduct, the return of this organ coming from the "watch chain" which drives in real time the disk-diagram; it is also possible to provide a return by a device of the electromagnet or bimetallic type controlled by

an electronic circuit.

  These different devices are complex in structure and expensive to produce, so that the automation

  registration in a driving position, the main

  cipe is naturally very seductive, implies

  which discourages many manufacturers.

  An object of the invention is to propose a device

  registration system which may enter into automatic

  as soon as the vehicle is running, and which is

  simple design while having high reliability.

  Another object of the invention is to obtain a

  easy-to-read "driver-time" recording.

  Another object of the invention is that the proposed registration device is easily adaptable for a

dual-driver application.

  A final object of the invention is that the provision

  compatible with an "intrinsically safe" type approval for the transport of

  dangerous goods by road vehicles.

  The invention relates to a registration device

  for road recorders, which may enter into

  as soon as the vehicle is running, including

  inscribing means for obtaining an outline of

  recording on a chart disk and a multi-position guide cam cooperating with the listing means so as to obtain a plot thus accounting for different types of use of the vehicle,

  characterized by the fact that it comprises additional means

  guiding elements which can be substituted for the cam of

  multi-position guidance, in whatever

  said positions, and actuating means,

  driven by the vehicle speed chain, realizing self-

  said substitution as soon as the vehicle is in operation for the listing means to produce a

  plot corresponding to a driving position.

  According to an advantageous characteristic, the additional guiding means consist essentially of an additional cam coaxial with the multi-position guide cam, whose inner radius makes it possible to

  capping said cam at several positions to substitute

  to kill it automatically in the driving position.

  Preferably, the additional cam comprises a support ring that can slide on the trunnion of the cam at several positions, and a lateral bar whose cross section has the shape of a meniscus,

  bar cooperating automatically with the means

  drivers in driving position to obtain a plot of thickness greater than that of the tracks obtained with the cam at several positions; the cam with several positions and the additional cam are advantageously rotationally fixed and subjected to the action of a spring tending

to move them away from each other.

  According to another advantageous characteristic, the

  actuating means for the automatic substitution of

  that in driving position essentially comprise a

  drum whose rotation is controlled by the chain

  se of the vehicle and a lever cooperating at one end with said drum and at the other end with the additional guide means so that this substitution occurs as soon as the speed of the vehicle exceeds a predetermined threshold; for example, the drum has a circular track against which the associated end of the lever

  is in support, said track being interrupted by a still

  an inclined ramp which can cooperate with said end when the speed of the vehicle goes from zero to the predetermined speed threshold, and said drum further carries the axis

  of the indicator needle of the tachometer.

  The device then advantageously comprises means allowing 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 in motion on a short beach.

  angle the vehicle's speed chain right from the

  the speed threshold, the said angular range being

  sufficient for the automatic substitution to be

  Lisée. According to a variant, the listing means, of

  guidance and actuation are split for one record-

  on two diagram disks, so as to distinguish the use of the vehicle by one of two drivers, the vehicle speed chain controlling the actuating means for the automatic substitution in any one of the two kinematic chatters; when a control drum is provided as before, said drum is preferably common to both kinematic chains, the doubling intervening for the

  lever, guide means and listing means.

  Other features and advantages of the

  will become clearer in the light of the

  description which follows and the attached drawing, in

  in the figure of the single plate illustrating a schematic

  in partial section, a preferred embodiment

  of a registration device in accordance with the

vention.

  The illustrated registration device includes

  listing means 1 for obtaining a registration

  on a chart disk 2 driven in accordance with

  real time by a watch 3, and control means 4 acting directly on the listing means 1 for a plot reporting the different types

of use of the vehicle.

  The control means 4 are here in direct contact with the drive motor of the watch 3, and it is

  provided a multi-position guide cam 5 cooperating with

  with the means 1 in order to obtain a

  whose thickness corresponds to each of the said positions

  tions. The direct movement is thus achieved by meshing of a pinion 6 mounted on an output shaft 7 of the driving motor of the watch 3, on a pinion 8 forming the beginning of the kinematic chain of the control means 4, this chain continuing with pinions 9, 10, to drive a pin 11 on which slides freely cam 5, the assembly being maintained by

  fixed elements 12, 13 secured to the casing 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 on the front of the casing and acting on a member 17 serving as a pusher for said cam.

  The choice of tracks, both in terms of their

  as to their shape, determines the mode of

  its thickness. Here track 16 is circular and corres-

  lays at a rest position, the record on the portediagram 2 disk translating into a single dash

  circular end. The non-circular tracks 16 'and 16 "cor-

  respond to two working positions at a standstill, by

  example loading / unloading and repair respectively

is lying.

  We will now describe the organs that allow

  attempt to have an automatic registration in driving position, without the need for any manual control.

  In accordance with a fundamental aspect of the invention

  the device also comprises additional means of

  guide members 18 which can be substituted for the cam 5, and in any position thereof, as well as actuating means 19, controlled by the speed chain of the vehicle, automatically realizing said substitution as soon as the vehicle is running for

  that the inscribing means 1 produce a corresponding plot

  laying at a driving position.

  The additional guide means 18 may be made 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 multi-position cam 5. The cam 18 comprises a support ring 20 slidable on the pin 11, and a lateral bar 21 whose cross section has the shape of a meniscus; it is this sidebar which "caps" the cam, so to speak.

  when it acts as support for the roller 14.

  For a good transmission of movement, it is interesting that the cams 5 and 18 are solidary in

  rotation. This solidarity is illustrated by the

  wise of the end 22 of the cam 5 in a lateral opening

  23. The journal 11, whose movement is controlled from the watch movement 3, carries a pin 24 engaging in a longitudinal groove 25 through the support ring, so that the cams 5 and 18 subjected to the action of a spring 26 tending to move away from one another, rotate permanently, and whatever

their relative axial position.

  It should be noted that for the variant shown, the tracks 16 'and 16 "have the minimum radius 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

  inscription mode and chosen plot thickness.

  The actuating means 19 are engaged with the vehicle speed chain: block 27 schematizes the conventional gearing, with an output pinion 28

  which serves, in known manner, to control the needle of the

  chymeter 29 and the 30 inscribing means of speed

  (schematically illustrated). A drum 31, which rotates

  tion is controlled by the pinion 28, through an auxiliary gear 32, has a circular track -8- interrupted by an inclined ramp notch 33. A lever 34, here articulated, cooperates at one end with the notch with an inclined ramp 33, and at its other end with a

  washer 35 resting against the cam 18.

  Thus, as soon as the speed of the vehicle exceeds a predetermined threshold, that is to say when the drum 31

  turned at a sufficient angle so that the correct end

  corresponding to the lever 34 is disengaged from the notch 33 (posi-

  illustrated in phantom), the other end of the lever pushes the cam 18 towards the cam 5, against the action

  26. Due to the coupling of the two cams, the bar

  Rette 21 is always positioned radially, to avoid a stop against the roller 14 which would prevent the cam 18 to cap 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 is based at the moment

  o you move to the driving position.

  It is also advantageous to provide further means for a sudden automatic substitution of the cams 5, 18 in the driving position, as soon as a very low speed threshold (0.1 km / h for example) is reached. One can provide for example a servo (not shown) setting in motion on a short beach

  corner of the vehicle's speed chain, right from the

  this low threshold; abrupt substitution, obtained artificially by electronic means, preferably by mechanical means, avoids the inconvenience

a transitional phase.

  For example, you can order the subscribe

  in the driving position as follows: - stationary vehicle: the tachometer hand is at the stop, fictitiously displaying 8 km / h; -9- - vehicle in very slow advance: from 0.1 km / h in real speed, the aforementioned means advance the needle abruptly up to a fictitious speed displayed of 11 km / h (this advance causing the substitution of the cams previously described, so that the plot corresponds to a driving position); - vehicle in normal advance: as soon as the actual speed reaches the threshold of 11 km / h, the tachometer needle

  normally displays speed, beyond the thresholds

  previous events of 8 km / h and 11 km / h.

  For a recorder of the tachograph type, there is provided a stacker (not shown) in which are arranged the recording means 1, the control means 4, the cams 5 and 18 and the actuating means 19, while an articulated cover (Not shown) supports the watch 3 and the record carrier 2. The direct movement of movement on the watch, to control the cam 5 and the inscribing means 1, thus takes place as soon as the hinged cover is closed, from which the pinion 6 towards the housing; this makes it possible to have on the chart disk a thickened path when the vehicle is stationary, this path having a thickness specific to each position of the cam 5, therefore to each type of use for the driver. As soon as

  vehicle is running, cam 18 is automatically substituted

  camming the latter, and a pattern with a still different thickness is obtained, so that

  that the reading of the chart disc is very easy.

  If one wishes to have a variant dual-drivers, it is sufficient to provide a second kinematic chain with

  similar means. It is rational whereas the second

  the second channel uses, on the one hand, for the cams and the means that are specific to it, a direct power take-off on the watch (with pinion 9 for example), and on the other hand, for the lever its own action, a power take-off on the chain

  vehicle speed with a common control drum.

  For the diagram carrier (s), it is possible to adopt, with a cam with three tracks, one of which is circular, the mode of drawing the following heater times in four thicknesses:

  - fine line in rest position (illustrated by the symbol

  bole i) - drawing of 0.8 mm in working position 1, eg loading / unloading, (illustrated by the symbol d) - drawing of 1.6 mm in working position 2, for example

  repair (illustrated by the symbol IS).

  - a 2.4 mm position in the driving position, recorded

  This is automatically controlled regardless of the type of use when stopped (illustrated by the symbol 6).

  The invention is not limited to the embodiment of

  tion which has just been described, but includes any variant

  which would use, with equivalent means, the characteristics

  essential features of the claims.
