DESCRIPTION
The present invention relates to a device installed on a motor vehicle, among others, allowing on the one hand to automatically activate the instrumental functions and / or equipment when moving in reverse of the vehicle and on the other hand to perpetuate this activation that the gear ratio of a gearbox, or the like, is engaged or not and that in a necessary and predetermined maneuvering space in order to maintain an efficiency of comfort and optimum safety of the equipment thus controlled. The activation of the perpetuation can also be initially activated by a proximity radar standby or otherwise. The operating principle of the device remains the same regardless of the initial source of its activation.

 The present invention is applicable to other types of machines: a construction machine, a locomotive and the like. Any system possessing either a reverse and a forward movement is a rotation in one direction and a reverse direction to the previous one.

 On current vehicles, all functions are only controlled and are mainly functional when the reverse gear is engaged. In most designs as soon as this ratio is disengaged, as soon as the vehicle is in neutral or first gear, the controlled functions stop, become inoperative. As soon as the vehicle is sloping and the use of the reverse gear is not required, the functions controlled by the reverse gear are always inactive. The functions concerned are: 'for driving aids: reversing lights, rear wiper, proximity radars, folding the mirror (s) ...

 'for safety systems: reversing audible alarms, ... anti-recoil or anti-safety braking.

Therefore, in order for the functions controlled by the selection of the Reverse Run to be effective, it is imperative to engage at least, or even keep, the report of the Reverse Run. During maneuvers of the type of a slot or others, the constraints of handling of the gearbox are, of this design, important and imperative to control the instrumental functions concerned by this type of driving procedure whereas an operational context can relieving the pilotage charges imposed on a

 driver. Detecting a recoil without the reverse gear ratio thus improves safety by improving steering loads and making reversing alarms active, such as on trucks, among others.

For certain timing principles, an indexation on the speed of the vehicle is effective. They are obtained by combining two distinct and imperative functions which are the activation of the equipment by the reversing sensor and the perpetuation by the partial use of the speed sensor, used for the control of the front and rear window wipers, taking the speed a speed higher than 0 Km / h to ensure the deactivation of the equipment connected to this device. This principle involves significant functional limits, such as during a low-speed movement, which induces a confusion of context. Equipment functions can thus be maintained over uncontrolled distances, especially if the deactivation is performed above a high speed. Otherwise, an inadvertent deactivation of the equipment is to be feared. The design of this type of deactivation, according to this principle of speed, requires the mounting of a switch actuated by the driver to cancel unwanted operations, especially if the systems are automatically activated below a certain speed. Despite this development of design, said current systems almost always retain the obligation to engage the reverse gear to get the equipment in action, which limits a whole functional context of use such as the realization of a niche sloping with a possible retreat without the commitment of the gear ratio. If the automatic activation of equipment according to the reference speed was systematically adopted, during congestion, the equipment would become frequently operational and disrupt the driving of the owner of a vehicle with this type of system, but also for others drivers located in a close environment. If the switch, mounted to avoid the aforementioned drawbacks, is permanent the risk of forgetting that the equipment will not be functional during a maneuver is important.

 Currently the mounting of driving assistance equipment such as proximity radars, the automatic rear wiper, reversing lights ... is often ineffective because of the principles of steering their implementation in action

 (from their start), reverse gear to engage, or control of the state of the alarm switch, or other.

 The equipment delay and control device, such as the reversing lights with the associated alarm, and / or others, according to the invention makes it possible to keep the functions of the equipment controlled during the engagement of the equipment active. reverse gear and / or after a short movement backwards and / or after its start by the manipulation of a command or other, when this report is disengaged, and this even after a moving of the vehicle forward on a short predetermined distance.

Par contre, si tel n'est pas le cas, aucune fonction n'est activée si aucune commande annexe n'active le dispositif, le véhicule recule, si le rapport de la marche arrière de la boîte de vitesses n'est pas engagé, les équipements sont activés par le système, faisant l'objet du présent brevet, selon leur principe de fonctionnement, en marche avant, sur une courte distance, les feux arrière de recul et les équipements commandés restent encore en action si le principe de fonctionnement préétabli le détermine, = > le véhicule recule après une marche avant, que le rapport de marche arrière de la boîte de vitesses soit réengagé ou non, les feux arrière de recul et les équipements pilotés resteront activés suivant chaque principe de fonctionnement préétabli, le véhicule recule après une marche avant et que les feux arrière de recul et les fonctions des équipements pilotés ont été, au préalable, désactivés, toutes les fonctions pilotées par le système sont alors réactivées suivant chaque principe de fonctionnement préétabli, que le rapport de la marche arrière soit réengagé ou non, The functional possibilities thus offered in the control of the equipment controlled during a maneuver are, among others, the following (in the

concept of gearbox ratio, it is necessary to integrate all the possible control systems that can intervene in the activation of the device at different times): => waiting for a reverse gear, if the ratio of the reverse gear the gearbox is engaged the equipment is activated according to their operating principle. On the other hand, if this is not the case, no function is activated if no additional command activates the device, the vehicle retreats, if the ratio of the reverse gear of the gearbox is not engaged, the equipment is activated by the system, subject of this patent, according to their operating principle, in forward movement, for a short distance, the reversing taillights and the controlled equipment are still in action if the operating principle pre-established determines it, => the vehicle retreats after a forward drive, whether the gearbox reverse gear ratio is reengaged or not, the reversing taillights and the driven equipment will remain activated according to each predetermined operating principle, the vehicle moves backwards after driving forward and the reversing rear lights and the functions of the controlled equipment have been previously deactivated, all the functions controlled by the sound system t then reactivated according to each pre-established operating principle, whether the reverse gear ratio is reengaged or not,

<Desc / Clms Page number 4>

 irrespective of the total distance traveled in forward movement during a maneuver, after a reverse movement a zero -0- of the counter of the space traveled in forward is automatic, after a continuous forward movement, determined beforehand, each piloted equipment returns to its predefined operating state by the driver before engaging and performing a maneuver. The reversing lights go out, among other things, each command to start and stop the controlled equipment can be differentiated in its sequences of operation of automation and sustainability.

The device of perpetuation and automatic control of equipment thus makes it possible to increase the safety by keeping the light signal of the reversing lights and the alarms which are attached thereto, inter alia, when a vehicle is maneuvering, this in a limited space and fixed in relation to the intention of the driver, but also by putting into action all the controls that improve the perception of the environment by the driver of the vehicle equipped with the invention, regardless of the direction of evolution of the vehicle. Piloted equipment can also have its own operating logic which is then differentiated from each other. The activation sequences of the equipment can be adapted according to the driving loads.

In addition, the piloting possible by the invention of an anti-recoil control and / or immobilization on the two axes of movement of a vehicle that would thus limit the risk of untimely downturns and / or his involuntary displacements.

 The system, which is the subject of the invention, uses the principle of the vehicle motion sensor, which can be the tachograph sensor, at the output of the gearbox or on AB S or other, for example, to perpetuate the activation of the equipment. connected thereto which has been initialized by the gearbox reverse ratio engagement sensor, or the like, or by the rearward motion detection device of the patented device. The principle is to measure forward motion to limit the space in which the sustainability function is maintained. The measure integrates all the displacements as well into

<Desc / Clms Page number 5>

 forward in reverse, which automates the activation, so that this measure does not include displacements whose meaning would be confusing and limit the interest of the equipment. The integration of the concept of reverse allows on the one hand not to cumulate sequences of steps before that would have, without this correction, as a consequence to stop unexpectedly the perpetuation of the activation of the equipment during the realization of a complex maneuver and secondly to automatically reactivate the durability of the equipment if it had been interrupted for a reason for moving forward more than a tolerated amplitude that is predefined.

This principle thus makes it possible to limit the distance of perpetuation according to a context reference known as maneuvering.

 By integrating the measurement of the displacement in reverse the invention makes it possible not to need the sensor of the gear ratio commitment of a gearbox, or other, to initialize the durability of the activation of equipment. The system is autonomous.

The reverse gearing sensor then only makes it possible to slightly anticipate the activation of the equipment. A new or several new functions may, after modification of the transmission engagement sensor of the gearbox itself, be released from this new equipment as represented in this patent is a device for securing the invention or the obtaining a different and additional timing based on gear ratios engaged, for example.

The device also makes it possible to optimize the parking aids based on proximity radars which, according to the current design, do not differentiate the operational contexts which requires the mounting of an alarm switch so that they do not trip unexpectedly. that the vehicle is in a traffic jam.

 By detecting the threshold of movement in both directions for an initialization of a backup braking, the proposed equipment responds to a requirement of safety immobilization of a driverless vehicle in the driving position. It also responds to any need to power a transmitter, or radar, or other that will provide signals to driving aids on the vehicle followers.

<Desc / Clms Page number 6>

 Each function of the equipment controlled by the system which is the subject of this patent retains its principle of putting into action which is specific to it. Only an enlargement of the operating contexts of the equipment is affected. An optimization of the equipment is thus obtained by relieving the driving loads of the driver.

The permissible reverse travel threshold is exceeded, in advance, if the controlled equipment is initialized by the commitment of the reverse gear or a retraction already made, the equipment remains activated, otherwise it is activated or reactivated. Simultaneously the distance calculation counter traveled in forward is set, or reset, to zero-0-.

 However, the actuation of the computer can be obtained as soon as one or more commands, -6-7a-7b-40 -... is activated, which has the effect of transmitting the signal-S3-which has the same effect as the signal-S1-.

 ') the vehicle stops: the system remains stable. The computer is neutral and provides no signal that would have the effect of confirming the initial state of the activation or deactivation of the equipment being controlled. On the other hand, it would change the reference of the distance possibly traveled forward. in memory in the calculator-2-.

') the vehicle is moving forward: the calculator-2-measures the distance of the forward movement according to the following principle: 0 as long as a threshold of distance to be traveled in forward direction is not reached, the controlled equipment remains operative according to their piloted states, 0 the forward travel threshold is not exceeded and the vehicle moves back slightly, the reversing computer measures the distance traveled by filtering and if this filtering threshold is exceeded, a command control pulse or / and reset -0- of the forward computer is issued.
This function allows successive forward movements without accumulation of distances.

 0 The travel threshold traveled forward is exceeded, the distance calculator traveled forward sends a signal that disables or resets the equipment according to their initial functions. It can also control the safety equipment if this function is searched by the -40- command.

 From this calculation module-2-control signals are emitted on one of the outputs that correspond to one of the directions of the evolution of the vehicle. These outputs are connected to the power control module of the controlled equipment-5-and the control of the back-up alarm or a possible system of anti-recoil or immobilization of a vehicle.

 level of the calculator-2-will therefore also increased to meet the functional requirements of the controlled equipment.

The specific principle of the signal generation, its processing and the power control, described through the figure -1- of the plate-1 is established progressively through that of the modules-3 and 4 -, - 2-, -5-.

The technical solutions may be different depending on the technology embedded on vehicles: analog, digital, digital computer, multiplexing or not.

As defined in Figure 2 Plate 2: the module -2- DISTANCE CALCULATOR-, of electronic form, the representation of which takes into consideration only one delay stage and therefore a delay value (one for each direction of the possible evolution of a vehicle) according to a single distance value traveled, but other delay values can be added to this device, comprises five inputs which are respectively: => 51 - input of the reverse signal connected to the corresponding output of the module-4-, => 52 - input of the forward signal connected to the corresponding output of the module-4-, => S3 - input of the signal of the activation of the devices controlled by a command connected to the corresponding output of the module-
5-and to the signal-43-, => 41 - input of the signal of the activation of the command-40-which initializes, by the signal-43-, the detection of a movement in forward motion in order to obtain a safety immobilization, or / and others, of a vehicle, => 8 e - input of the power supply of the module, and four outputs: = S 1 a-the output of command of automatic activation of the equipment driven by reverse gear, => S2c-the control output of stop of the operation of the controlled equipment, => S2a-the output of the odometer and the tachograph-12-of the car,

<Desc / Clms Page number 12>

 sala control output of possible start of safety equipment during a dangerous or unwanted forward step.

The number of outputs -81a and S2c-may increase according to the needs in sensitivities and delays in the activation and / or deactivation of the controlled equipment. If this is the case, one or more output connections from the sub-modules -13b- for the activation of the durability and -14b-for the deactivation are possible.

To achieve this function of starting or automatic shutdown of the controlled equipment and therefore of their permanent operation, according to the two active principles of the initial operation of said equipment, the module-2-consists of two axes of calculations of distances traveled, one for each direction of evolution of the vehicle. Each axis manages its distance but also controls the distance calculator which takes into account the parameters that intervene in the evolutions opposed to its own direction of movement of the vehicle. Each axis consists of two sub-modules-13 and 14-which intervene as follows: For the axis of reverse, the sub-module -13-:
The device component-13a-, initialized by the signal -Sl-or / and -S3-, counts the filtering distance traveled in reverse. As soon as a threshold of distance in reverse is made, two signals are emitted whose functions are respectively for: 0 8lbl - to direct the signal-S2-, received by the device component-
14a, which has the initial function of informative support for the signal tachograph-S2a, to the informative support function, for the device component-14b-which then serves for the evaluation of the distance traveled in forward direction, Slb2-to reset-0-the distance traveled forward accumulated by the device-14b- component. This function makes it possible not to totalize all the displacements traversed in forward during complex maneuvers which would have the effect of early deactivating the functions of the equipment controlled by the system-1-.

 The component-13b component calculates the distance traveled in reverse for the automatic control of the activation of the controlled equipment. As soon as the threshold required by the piloted equipment

<Desc / Clms Page number 13>

 is reached, the latter delivers the signal -81a- which is directed to the power control module-5-which will activate the controlled equipment or devices. The number of S-outputs will depend on the number of times required. The time delay options, before activation of the controlled equipment, according to the sub-module reference - 13-, can range from the minimum filtering time, in order to avoid parasitic displacements, to an unlimited time. As a result, BUZER type reversing alarms can be controlled by this device.

=> For the forward axis of the sub-module-14-: The component device-14a-pilot initially, at rest, the signal -S2- towards the signal-S2a-and which is the informative support for the reference of odometer and tachograph-12-. As soon as the latter perceives the signal -81b1- of the device component-13a-, the signal-S2-is oriented towards the device component-14b-.

The device component 14b then calculates the distance traveled forward from the signal S2 according to two logics:
1. cumulative logic when a stop is made in the move. On the other hand, if the vehicle recedes and the signal-
Slb2-is issued, the totalized distance is reset to -0-. Beyond a predetermined forward distance, the device component-14b-emits a signal which is oriented:> for the signal-S2c-towards the power control module of the controlled equipment-5-. Its function is to deactivate the durability, for the signal-S2b-to the sub-module-13a-in order to de-initialize the signal -8lb1- which drives the component device-14a-in the distance calculation mode traveled forward to from the signal-S2-so that this signal becomes the signal-S2a-of the odometer and speed. Simultaneously, the signal-S2b-also returns the distance counter traveled forward to zero-
0-.

 2. a non-cumulative logic which emits the signal-S4-which activates the equipment connected to the power circuit concerned only if this action is tolerated by the activation of the thyristor-42- itself driven by a signal emitted at its trigger by the switch-40-.

<Desc / Clms Page number 14>

As for the number of outputs-S la-, the number of outputs-
S2c-depend on the number of timers required.

The operating principle of the computation module-2-of distance traveled in front can be of electronic design principle analog or digital with components MOS or others but also computer. In computer design, a device for adapting signals-SI, S2 and S3-, for the treatment of distances traveled and signals-Sla-
S2c-and S4-for controlling the module-5-power control of the controlled equipment, will be integrated into the system that is the subject of this patent.

 For the computer version of the computer, the operating principle of the software is a loop management of the signals emitted by the vehicle-4-motion detection module during a movement of the vehicle which is, for example, the following:.

 In advance, the computer software watches over the appearance of the reverse signal-SI-or signal-S3-. In this loop management of information, the software considers the signal-S2-as being a speed and distance information which is oriented towards the tachograph, =:> As soon as the signal-SI-or-S3-is perceived, the The software initializes the calculation loop of the distance traveled in reverse and counts a filtering distance in order to avoid any erroneous interpretations of the real trends of the vehicle's movement. Simultaneously, a zero -0- reset of the distance traveled in forward is systematically performed, as with the signal -Slb2-.

The filtering threshold is reached, the software initializes the standby loop on the distance that will be traveled forward for the durability of the controlled equipment and which will be established from the signal-S2-whose destination is no longer then the tachograph ,
Depending on the threshold of awareness sought for the automatic activation of the piloted equipment whose functions will then be perpetuated, the software calculates the distance traveled in reverse, except the filtering distance. The distance reached, the software opens the loop of the activation of the equipment concerned by this activation distance. It generates the signal-Sla-which activates the power control module of the equipment-5-. This loop

<Desc / Clms Page number 15>

 The calculation time is extended until the equipment is fully activated or until the vehicle changes direction.

 => As soon as the vehicle advances the loop of the software perceives the signal-S2- which then modifies the selection of the loop of the software which, then, takes into account in the calculation of the distance covered only the signal -set in standby the signal -S 1-.

 As long as the vehicle advances the software loop totals only the forward distance, as long as the deactivation threshold is not reached.

 => If the vehicle stops, the software remains waiting on the loop initialized before stopping. He remains waiting.

 => If the vehicle recoils, the software resets the computation loop in reverse and returns the memory of the distance counter traveled forward to zero -0-.

 => If the vehicle moves forward and the distance threshold to deactivate the durability of the controlled equipment is reached, the software loop goes to the signal transmission phase S4-, which activates the safety equipment if this function is sought, either later, or S2c-disabling equipment at the level of the power control module-5-.

 => This last operation carried out the software is reestablished on a standby loop of the signal -81- which will reset the process of automation of the activation of the controlled equipments as well as their perpetuation.

 The activation and deactivation loops can be multiple, they will depend on the conditions sought for the activation and durability of the functions of the controlled equipment.

 As shown in FIG. 3, plate 3: the modules-3 and 4-the device for detecting the direction and the amplitude of the displacement of the vehicle.

The module -3- consists of a phonic wheel, tachograph or A. BS, for example, which includes two inputs: => -8a-for the power supply of the sensor in normal mode => -40b-for the day before a movement, during a complete immobilisation of the vehicle, which will have the effect of initiating the emergency braking for example and two outputs:

The mass.

The module-4-consists of two sub-modules: Sub-module-4a-DEFINITION OF ROTATION DIRECTION, it detects the inversions of the characteristics of the signal-S-emitted by the phonic wheel-3-depending on the direction of the moving the vehicle.

 This function can also be controlled by a complementary sensor for detecting the direction of rotation.

 According to the perceived characteristic, the S-signal is oriented either on the output: IF-for reverse, S2 - for forward travel.

 During a stop no signal is perceived.

The technical design of the function-OR-of the differentiation and the orientation of the signal-S-can be a filtration of the direction of the progression of the signal, for example, or its control, => Sub-module-4b- SIGNAL ADAPTER, depending on the technical principle of the computer-2-a signal processing-SI or
S2-is performed to make it usable by it. The modulation of the signal is obtained from a transistor amplifier, for example.

The signals-SI and S2-are oriented by the module-4-to the outputs-SI and S2-connected to the inputs of the distance calculator-2-previously described.

pour le composant-45-une activation du freinage de secours de veille de sécurité. As shown in FIG. 4, plate 4: the power control device, module-5-, comprises three circuits, two of which are of inverted operating principle, which are: for components-15a and 15b-an activation of the equipment when a recoil, as for the reversing rear lights, 'for the components-16a and 16b-a deactivation of the equipment for the same maneuver, and the third is:

for the component-45-an activation of safety standby emergency braking.

The operating principle is as follows for:

activation during a recoil:
In a normal context, the field-effect transistor-15a-passes the power-8b- (power-8-) current which serves to supply directly, or indirectly with the contribution of a power relay, the equipment connected to terminals-10a and 10b-. These are not activated as long as the signal-S the-emitted by the computer-2-at the trigger of the thyristor-15b-does not make it last driver.

La désactivation des équipements est aussi obtenue lors de la coupure du courant-8b- (8) consécutive à l'arrêt du moteur ou provoquée à l'aide d'un interrupteur complémentaire placé au niveau du poste de conduite. The thyristor-15b-driver equipment is activated and therefore the functions are perpetuated regardless of the type of movement of the vehicle in the limit (s) permitted by the displacement calculator-2-. As soon as the permissible limit for a movement in the forward direction is reached, the displacement calculator 2 transmits the signal S 2c to the gate of the field effect transistor 15a which has the consequence of interrupting its conductivity and therefore the Current-8b- (8) no longer passes to power equipment. In addition, since the vehicle no longer moves back and the signal -S 1a is no longer transmitted, the thyristor

- 15b- is also non-conducting. Sustainability is therefore interrupted until a new setback emits the signal-S la-which would reactivate the function of equipment and their sustainability. The deactivation of the equipment is also obtained when the power cut-8b- (8) is interrupted when the motor stops or is caused by a complementary switch placed at the driver's seat.

The signal-S la may be replaced by a current-8c and / or 7b-emitted by the sensor of the reverse gear engaged-6-or a switch-
7a-placed at the dashboard or other. In order to activate the devices during a start-up, the gate of the thyristor can be connected to the NEIMAN (g) -7b-or other, which delivers the signal-8f-to the gate of the thyristor-15b-.

courant-9b-délivrée par l'interrupteur qui permet le passage du courant de puissance-9a-qui alimente les équipements raccordés à la borne-11- du système-1-. Dès que le véhicule recule le signal-Sla-est perçu par la porte du transistor à effet de champ-16a-ce qui a pour conséquence d'en arrêter sa conductibilité. Comme la gâchette du thyristor n'est plus sous =? for reverse operation, deactivation during a recoil: in a forward-off-maneuver context, the equipment is activated since the field effect transistor-16a is conducting and the trigger of the thyristor-16b has been under voltage by a pulse of

current-9b-delivered by the switch which allows the passage of the power-9a-current which supplies the equipment connected to the terminal-11- of the system-1-. As soon as the vehicle backs the signal-Sla-is perceived by the gate of the field effect transistor-16a-which has the effect of stopping its conductivity. As the trigger of the thyristor is no longer under

<Desc / Clms Page number 18>

tension ce dernier perd aussi sa conductibilité. Donc même si le transistor à effet de champ-16a-redevient conducteur les équipements reliés à la borne-11-du système-1-sont désactivés tant que le signal-
S2c-, de la marche avant, émis au niveau de la gâchette du thyristor- 16b-n'aura pas rendu ce dernier conducteur.

This voltage also loses its conductivity. So even if the field-effect transistor-16a-becomes conductive again the equipment connected to the terminal-11-of the system-1-are deactivated as long as the signal-
S2c-, the forward, issued at the trigger of the thyristor-16b-will not make the latter driver.

l'ouverture du contacteur-40-, ou autre qui arrête l'alimentation en puissance-44-de l'équipement piloté initialement par le contacteur-40- puis par le thyristor-45-, dont le principe de pilotage est identique au thyristor-15b-. And a watch circuit that groups together the immobilization control function of a vehicle according to the reference of the two directions of its possible evolutions: => Security watch:
In the context of stopping a vehicle, the search for a potential secure immobilization can be sought. In this design a contactor-40-puts in sleep the displacement sensors of the calculator - 2-, one for each direction of potential displacement of the vehicle. The principle of activation of controlled equipment is identical to that of the reverse gear. The only difference is the requirement of the prior activation of the thyristor-42-which will make the direction of travel forward will be taken into consideration or not. This selection is obtained by activating beforehand the gate-41-of thyristor-42-which will allow the passage of one of the signals emitted by sub-module-14b-or-13b-by generating the signal-S4-which makes driver the thyristor-45-, or not. The deactivation of piloted safety equipment is obtained by

the opening of the contactor-40-, or other which stops the power supply-44-of the equipment piloted initially by the contactor-40- then by the thyristor-45-, whose driving principle is identical to the thyristor -15b-.

parvenir le capteur -6-, faisant partie du présent brevet, comprend une fourchette-22-, qui peut se situer sur le levier de vitesses, près des leviers de la boîte de vitesses, ou autre, qui possède une lumière afin de permettre un débattement sans modifier le positionnement du levier-21-. Quand le rapport de boîte de vitesses sélectionné est celui de la marche arrière, la fourchette-22-pousse le levier-21-en comprimant le ressort-23a-. Dès que le rapport de marche arrière est engagé la bille de verrouillage-25-, poussée As shown in FIG. 5, plate 5: The securing of the durability, or the complementary timing is of mechanical principle. They are enabled by locking on one of the two positions of the gear ratio sensor instead of the current-6-sensor which does not include a locked position. For

to reach the sensor -6-, forming part of this patent, comprises a fork-22-, which can be located on the gear lever, near the gearbox levers, or other, which has a light to allow a deflection without changing the position of the lever-21-. When the selected gear ratio is that of reverse, the fork-22-pushes the lever-21-compressing the spring-23a-. As soon as the reverse gear is engaged the ball lock-25-, thrust

<Desc / Clms Page number 19>

 by a spring-26-, engages in the locking latch-CR2-located on the contactor core-19-. The contactor core 19, by the contactor-18 located at its end, makes the electrical connection which feeds the system - 1-at the inputs-8 and 8c-, and / or directly supplies the equipment connected to its output- 28-.

When the reverse gear ratio of the gearbox is disengaged, the fork-22-moves in the opposite direction to that of the reversing engagement, without unlocking the contactor core-19-. The contactor-18-feeds, in this state of fact, always the equipment connected to the terminal-28-this contactor.

As soon as the second gear, or another, is engaged the fork-22-moves even more in the opposite direction to that of engaging the gear ratio and pushes the lever-21-. When the threshold necessary for the unlocking of the contactor core 19 of the crank-CR 2 is reached the spring 23a repositions in the configuration of rest, on the cran-CRI, the kernel contactor 19 and consequently the contactor. 18-which has the effect of interrupting the supply of equipment connected to this sensor-6-.

 As shown in FIG. 6, plate 5: the principle of the sensor-6- is in this mechanical pulse description. To achieve this principle of operation, the sensor-6-is necessarily connected to the system-1-or a thyristor-29-, for electrical control, and a flexible mechanical connection.

The flexible connection is made from the lever-21-which has a housing in which is positioned the contactor core-19-and two springs-23a and 23b-positioned on either side of a shoulder located on the core contactor. Said lever 21 is integrally connected to the fork 22. When the speed ratio of the reverse gear is engaged, the lever 21 through the fork 22 compresses the spring 23b. As soon as the compression is sufficient to release the locking ball 25, compressed by the spring 26 from its notch, the contactor core 19 unlocks its cran-CRI rest position to position itself on the cran-CR 2-. The contactor-18-located at the end of the contactor-19 cores the connections either by pulse at its terminal-30-, which corresponds to the pulse-8f-for the system-1-or a pulse at the trigger of thyristor- 29-, which will allow the conductivity of the system-1-or thyristor

<Desc / Clms Page number 20>

 - 29-which will supply power to the controlled equipment, either continuous, for buzer-type equipment and / or others that are connected to the terminal-31-sensor-6-.

The connection of the controlled equipment is possible because the switch-24- comprises three separate tracks: the continuous and power supply track of the contactor-18-, or the supply-27-, an intermediate supply track. power-28-. Runway-28-, which supplies system-1-or thyristor-29-, is energized only when contactor-18-simultaneously connects tracks-27 and 28-. On this configuration the power-8-system-1-or-28-thyristor-29-power supply is energized when the contactor core is in the idle position and when the gear ratio, or neutral or the first forward gear is engaged. The system-1-or thyristor-29-is conductive in the previous configurations only when the reverse gear is selected. During this maneuver, the contactor-18-comes into contact with the connection pad which supplies the system-1-to its terminal-8f-or the gate of the thyristor-29-thus the conductivity of the system-1-or the thyristor- 29-is obtained. The equipment controlled by this sensor by either the system-1-or by the thyristor-29-are activated. Indeed, this principle is made possible because the contactor-18-simultaneously connects the track-27-with the track-28-but also with the track of the -8f-command of the system-1-or also with the power supply of the trigger of the thyristor-29-by the connection-30-. In abutment, the contactor-18-connects equipment connected to the track and connection-31-which will be powered only when the ratio of the reverse gearbox will be engaged.

When the gearbox ratios are changed, the lever-21- compresses the spring-23a-until the locking force is exceeded then the contactor core-19-emerges from the notch CR2-for reposition on the cran-CR1-. Therefore, the contactor-18-is no longer in contact with the output-31-and the equipment powered by this source stop being activated. On the other hand, since the system-1-is controlled for its deactivation by the distance traveled in forward direction, the equipment that is connected to this device will retain their initialized states when the reverse gear ratio is engaged as long as the distance tolerated will not be exceeded. As soon as it is reached the deactivation of the perpetuation is effective. For the thyristor-29-, as this one is

<Desc / Clms Page number 21>

 driver and that the power supply on terminal-30-has not been interrupted, it remains conductive. This situation is maintained as long as you stay in neutral or with the first gear engaged. As soon as the operation of the selection of the second report of the gearbox is engaged, the lever-21-compresses again the spring-23a-. As soon as the compressive force is greater than the locking force, the contactor core 19 moves until the contactor-18-no longer connects the track 27, which is continuously energized. , with track-28-which is then at zero potential -0-. Therefore, as the power supply-8-system-1-is interrupted the perpetuation is interrupted whether the forward distance has been reached or not. As a result, the system-1-is secure. As the thyristor 29-as its conductivity was interrupted the latter does not become conductive until its trigger is reactivated by an electric pulse obtained when engaging the ratio of the reverse gearbox. Similarly for the system-1-.
