Definitions

  • the present invention relates to the field of thermal motor starters, especially motor vehicles.
  • One of the means of the state of the art to avoid this problem is to introduce electronic timers so as to wait a predetermined time after stopping the engine to transmit power to the pinion. This delay ensures that the pinion has time to mesh on the ring before transmitting the power of the starter motor to the pinion. However, this delay tends to harm the comfort of the user by increasing the restart time of the vehicle engine and also tends to complicate the electronic programming of the vehicle.
  • the object of the present invention is therefore to provide a solution making it possible to avoid a Milling of the crown by the pinion during a reflex restart while minimizing the time required for restarting.
  • the switch is arranged such that the transition from the rest position to the active position of the secondary contact pad is made when the starter gear is in a position corresponding to being geared on the crown of the engine.
  • the at least one electrical terminal main is placed in a first branch of a power supply circuit of the electric motor and the at least one secondary electrical terminal is placed in a second branch of the power supply circuit of the electric motor, the first and the second branch being mounted in parallel.
  • the plunger rod when the movable portion of the magnetic core is in the active position and the plunger and the plunger rod are in the first position, the plunger rod causes the contact plate to be moved to the active position.
  • the main electrical terminal is connected to at least one positive brush of the electric motor of the starter and the main contact plate is connected to a power source.
  • the main electrical terminal is connected to a power source and the main contact pad is connected to at least one positive brush of the electric motor of the starter.
  • the contactor comprises a first and a second main electrical terminals for supplying the electric motor of the starter, the first main electrical terminal being connected to a power source and the second main electrical terminal being connected. at least one positive brush of the electric motor of the starter, the main contact pad coming into contact with the first and the second main electrical terminal in its active position.
  • the secondary electrical terminal is connected to at least one positive brush of the electric motor of the starter and the secondary contact plate is connected to a power source.
  • the secondary electrical terminal is connected to a power source and the secondary contact pad is connected to at least one positive brush of the electric motor of the starter.
  • the contactor comprises a first and a second secondary electrical terminal for supplying the electric motor of the starter, the first secondary electrical terminal being connected to a power source and the second secondary electrical terminal being connected. at least one positive brush of the electric motor of the starter, the secondary contact plate coming into contact with the first and the second secondary electrical terminal in its active position.
  • the present invention also relates to a starting system of a heat engine comprising a starter, the system comprising an electronic control unit configured to drive the actuator in an active position when the starter performs a start in reflex mode.
  • the electronic control unit is configured to drive the actuator in a rest position when the starter performs a cold start or a direct mode start.
  • the electronic control unit is configured to supply the wound element in case of starting.
  • the actuator is electrically connected between the electronic control unit and the ground.
  • the actuator is electrically connected between the electronic control unit and a positive brush of the electric motor.
  • the plunger rod 13 is connected to the pinion 17, for example by means of a fork 19 so that the displacement of the plunger rod 13 causes the pinion 17 to move.
  • the passage of the movable part 9b the magnetic core from the rest position to the active position causes the pinion 17 to move towards the ring 21 of the heat engine 23.
  • the contactor 5 which is represented alone on the figure 1b , also comprises two main electrical terminals 25a and 25b.
  • the first main electrical terminal 25a is connected to a positive brush of the electric motor 27 of the starter 3 and the second main electrical terminal 25b is connected to a power source, in this case the terminal positive + noted a battery 29, for example a 12 or 14V battery in the case of a starting system 1 of a motor vehicle.
  • the contactor 5 also includes a secondary contact plate 37 adapted to be moved between a rest position in which the secondary contact plate 37 is electrically isolated from the two secondary electrical terminals 35a and 35b and an active position in which the secondary contact plate 37 comes in contact with the two electrical terminals secondary 35a and 35b to supply the electric motor 27.
  • the passage of the secondary contact plate 37 from the rest position to the active position being caused by the plunger rod 13 which comes into contact with the secondary contact plate 37 during the active portion of the movable portion 9b of the magnetic core is passed under the condition that the plunger 11 and the plunger rod 13 are in the first position.
  • the plunger 11 and the plunger rod 13 are displaced, which also causes the pinion 17 to move towards the crown 21.
  • the pinion 17 can not mesh with the ring 21 and is locked in position tooth against tooth on the ring 21.
  • This blocking of the pinion 17 causes the locking the plunger rod 13 via the fork 19 so that the plunger rod 13 can not move to the active position which causes the compression of the spring 15 and prevents the movement of the secondary contact plate 37 from the position of rest at the active position.
  • the main electrical terminals 25a and 25b associated with the main contact plate 31 constitute a first switch located in a first branch of the power supply circuit of the electric motor 27 while the secondary electrical terminals 35a and 35b associated with the contact plate secondary 37 constitute a second switch located in a second branch of the power supply circuit of the electric motor 27, the second branch being mounted in parallel with respect to the first.
  • Activation and deactivation of the actuator 33 and the wound element 7 are performed by an electronic control unit 39 of the starter system 1, the supply being represented schematically by a first 41 and a second 43 switch which in turn Practical examples may be, for example, transistors or other logic elements.
  • the electronic control unit 39 makes it possible, for example, to connect the positive terminal + of the battery 29 to the actuator 33 on the one hand via the first switch 41 and to the wound element 7 via the second switch 43.
  • the actuator 33 is activated by the closing of the switch 41 and the wound assembly 7 is activated by closing the switch 43.
  • the actuator 33 is electrically connected on the one hand to the switch 41 of the electronic control unit 39 and on the other hand to ground.
  • This electrical diagram corresponds to the representation of the figure 1a .
  • the electronic control unit 39 is also electrically connected to the positive terminal + of the battery 29 so that the closing of the switch 41 causes an electrical connection between the positive terminal + of the battery 29 and the actuator 33 when the secondary contact plate 37 is in the rest position.
  • the wound element 7 comprises two coils denoted 7a and 7b, on the one hand a holding coil 7a connected between the switch 43 of the electronic control unit 39 and the ground and an actuating coil 7b connected between the switch 43 of the electronic control unit 39 and a positive brush of the electric motor 27.
  • the two coils 7a and 7b are activated to move the movable portion 9b of the magnetic core from its rest position to its active position then only the holding coil 7a is used to keep the moving part 9b of the magnetic core in the active position so as to reduce the consumption of the wound element 7.
  • the actuator 33 is electrically connected on the one hand to the switch 41 of the electronic control unit 39 and on the other hand to a positive brush of the electric motor 27.
  • the other electrical connections are the same as for the first one. embodiment of the figure 2 .
  • the figure 4 represents an example of evolution over time of the engine speed of the engine 23, that is to say the number of revolutions per minute of the rotor and therefore of the ring 21, during a stopping of the engine 23 which has place at time T0. It is then observed that between times T0 and T1 the number of revolutions per minute decreases rapidly but irregularly, the curve being not straight but having rebounds during which the speed of the rotor rises slightly. From the moment T1 and until the complete stop of the rotor at time T2, the rotor enters a period of oscillations in which the rotational speed of the rotor can even be negative, that is to say ie the rotor rotates in the opposite direction.
  • the idea of the present invention is therefore to prevent any drive in rotation of the pinion 17 by the electric motor 27 during a reflex start by activating the actuator 33 unless the pinion 17 is geared completely on the ring 21 which allows contacting the secondary contact plate 37 with the secondary electrical terminals 35a and 35b so as to supply the electric motor 27.
  • the Figures 5 to 7 describe the different stages of a direct start or cold start.
  • the switch 43 is closed so as to activate the wound element 7 as shown in FIG. figure 5 .
  • the switch 41 remains open so that the actuator 33 is not powered and remains in the rest position.
  • the electric motor 27 is energized and causes the pinion 17 to rotate, which will then mesh with the ring gear 21. the combined action of the electric motor 27 and the spring 15 which acts on the fork 19 to move the pinion 17 to the ring 21. Indeed, as the electric motor has just started, the speed of the pinion 17 is low and the sprocket 17 gear on the ring 21 can be easily as shown on the figure 7 . The motor 23 is then launched by the rotation transmitted between the pinion 17 and the ring 21.
  • the Figures 8 to 10 describe the different steps of a reflex start, that is to say a start while the motor 23 is in stop phase.
  • the switches 41 and 43 are closed so as to activate both the wound element 7 and the actuator 33 as shown in FIG. figure 8 .
  • the closing of the switch 41 causes the actuator 33 to move into its active position, that is to say in a position preventing the contact between the main contact plate. 31 and at least one of the main electrical terminals 25a and 25b.
  • the supply of the wound element 7 causes the moving part 9b of the magnetic core to move towards its active position.
  • the displacement of the movable part 9b causes, on the one hand, the displacement of the main contact plate 31 towards the main electrical terminals 25a and 25b and, on the other hand, the displacement of the pinion 17 towards the ring 21 to an intermediate position. against pinion tooth 17 with the ring 21 as shown in the figure 9 .
  • the tooth-tooth positioning of the pinion 17 with the ring 21 causes the compression of the spring 15 and the passage of the movable portion 9b of the magnetic core in the second position.
  • the plunger rod 13 does not cause the displacement of the secondary contact plate 37 towards the secondary electrical terminals 35a and 35b.
  • the gear of the pinion 17 on the ring 21 also causes the decompression of the spring 15 and the passage of the movable part 9b in the first position so that the plunger rod 13 causes the displacement of the secondary contact plate 37 to the electrical terminals secondary 35a and 35b which allows the supply of the electric motor 27 via the secondary electrical terminals 35a and 35b.
  • the power supply of the electric motor 27 then causes the pinion 17 which is geared to the ring gear 21 to be rotated.
  • the motor 23 is then launched by the rotation transmitted between the pinion 17 and the ring gear 21 as shown in FIG. figure 10 .
  • a mobile part 9b of magnetic core comprising on the one hand a plunger 11 adapted to move a main contact plate 31 for controlling the power supply of the electric motor 27 and secondly a plunger rod 13 movable relative to the plunger 11, connected to the fork 19 and able to move a secondary contact plate 37 for controlling the power supply of the electric motor 27 according to the position of the pinion 17 relative to the ring 21 in association with an actuator 33 configured to inhibit the action of the main contact plate 31 in case of reflex start allows to obtain a mechanical safety that avoids the activation of the electric motor 27 driving the pinion 17 during a reflex start when the pinion 17 is not completely geared to the ring 21 of the engine 23.
  • This starter architecture 3 thus makes it possible to avoid any milling of the ring gear 21 by the pinion 17 without the need for electronic control or delay, which makes it possible to optimize both the time required for the restart and the life of the starter 3 and to limit at the maximum complexity of the electronic part of the starter 3 and therefore to limit the cost of the starter 3.
