Definitions

  • the invention relates in particular to a starting device for an internal combustion engine, especially a motor vehicle.
  • This contactor comprises a mobile unit composed of a plunger core on which is fixed a rod carrying at one of its ends a sliding mounted contact plate.
  • This plate is initially supported, in particular by the action of springs, on contacts of an electrical circuit comprising a winding resistor so that, in a first startup phase, the starter rotates at a low speed. In a second start-up phase, this same contact plate closes an electrical circuit allowing the starter to deliver its maximum torque.
  • the patent FR 2 827 341 describes an electromagnetic contactor with a power resistor to allow pre-rotation of the launcher.
  • the patent application FR 2 881 479 describes a control device of a starter with an electric motor. This comprises an inductor winding with four windings forming two groups in parallel each of two windings in series. A deferred electromagnetic switch is provided to allow, in a first phase, the activation of only one of the groups of windings and, in a second phase, the activation of the two groups of windings.
  • the invention aims in particular to solve the aforementioned drawback in a simple manner.
  • the first and second electrical contact elements can be easily arranged, if desired, in a single housing, which avoids having two contactor housings as described in particular in the patent application.
  • FR 2 881 479 is a single housing, which avoids having two contactor housings as described in particular in the patent application.
  • the first and second electrical contact elements may, if desired, be controlled as a function of displacements of elements of the device, independently of predetermined time constants.
  • the torque developed by the electric motor is lower than that developed in the second phase of full speed.
  • the electric motor can already be at least partially supplied with an electric current for a contact winding of the contactor. This can, if necessary, result in a small rotation of the electric motor.
  • the contactor is advantageously arranged in such a way that, in the first pre-rotation phase, the first electrical contact element is in the closed state and the second electrical contact element is in the open state, and in the second phase at full speed, the first and second contact elements are in a closed state.
  • the contactor comprises a movable assembly arranged to move the launcher by means of a pivoting fork, the moving assembly comprising an actuating element arranged to cause the closing of the second electrical contact element.
  • the contactor according to the invention can thus have a small footprint.
  • the mobile assembly of the contactor may comprise a movable core, the actuating element being movably mounted relative to this movable core against the force exerted by a elastic return element, in particular a spring.
  • the second electrical contact element may be integral, in particular with the possibility of sliding, of a control rod and the actuating element of the moving assembly may be arranged to be applied against the control rod so as to being able to push the latter to cause the passage of the second electrical contact element from the open state to the closed state.
  • the first contact element is advantageously carried, in particular with a possibility of sliding, by a movable support and the second contact element can be guided in displacement in this support of the first contact element.
  • the contactor comprises a fixed core, and an elastic return element, in particular a spring, is interposed between the second contact element and the movable support of the first electrical contact element so as to to allow, at least when the first contact element is activated and before the activation of the second contact element, to apply the second electrical contact element against the fixed core of the contactor.
  • an elastic return element in particular a spring
  • the device comprises a first electrical terminal connected to an energy storage source, in particular a battery, a second intermediate power terminal and a third full power terminal.
  • an energy storage source in particular a battery
  • a second intermediate power terminal in particular a battery
  • a third full power terminal in particular a battery
  • the first contact element comes into contact with the first electrical terminal and the second intermediate power terminal and, in the second full-power phase, the second electrical contact element comes into contact. with the first and third electrical terminals.
  • the first terminal connected to a source of energy storage can be staggered so as to allow the first and second contact elements to simultaneously bear on this first terminal, in particular at different heights of said terminal.
  • the device comprises a stator, or inductor, comprising an inductor winding, said inductor coil comprising at least first and second windings, and the contactor can be arranged to control, in the first pre-rotation phase, a power supply only of the first winding of the inductor winding, and in the second phase of full speed, a power supply of both the first and second windings of the inductor winding.
  • the device comprises at least one power resistor arranged in such a way that, in the first pre-rotation phase, the induction coil is electrically powered through the power resistor, in particular so as to limit the current peak in the electric motor and, in the second phase of full speed, the inductor coil is electrically powered by short-circuiting the power resistance.
  • the contactor is arranged so that the second electrical contact element is in the open state as long as the launcher is in the tooth against tooth position on the drive ring of the combustion engine.
  • the invention makes it possible in particular to reduce the torque peak as long as the launcher is in the tooth against tooth position on the ring gear, and thus to eliminate the risk of milling.
  • the invention may also make it possible to eliminate re-openings by return of the movable core which may appear in the case of a tooth against tooth position at the time of the conjunction (in which case a voltage drop due to the peak current of the motor electrical and short-circuiting of a contact winding of this contactor can induce a lack of strength to allow the movable core to come to magnetic bonding).
  • the peak current is limited in the electric motor, which reduces the electrical wear of brushes present in the electric motor.
  • the limitation of the torque peak makes it possible to reduce the mechanical wear of the pinion against the ring gear.
  • At least one of the first and second electrical contact elements may comprise an electrically conductive wafer.
  • the inductor comprises a winding with four windings in parallel, corresponding to four inductor channels, which allows cutting current peaks and torque significantly.
  • the invention also relates to a rotating electrical machine, including a starter or a reversible alternator of a motor vehicle, comprising a device as described above.
  • the control of the windings of the inductor winding can, if desired, be provided by switches, including electronic switches of the contactor. These switches comprise for example at least one transistor or thyristor.
  • control of the windings of the inductor winding can be ensured by the displacement of moving elements of the contactor.
  • the pre-rotation phase only a part of the windings of the inductor winding is fed, for example half or a quarter of the inductor winding, while in the second phase of full power, all windings of the inductor winding are fed.
  • the inductor winding may comprise four windings forming two groups in parallel each of two series windings.
