Definitions

  • the present invention relates to a protection system which prevents a deformation that will occur between a starter pinion and a flywheel ring gear during the initial starting off of vehicles, particularly tractors.
  • a starter solenoid triggers a starter pinion and the starter pinion moves towards a flywheel ring gear.
  • the starter pinion provides rotation of the flywheel ring gear by clutching it and this provides the first motion to the motor vehicle.
  • vehicle engines do not get the first drive according to above mentioned procedure and are not started . Even if the engine is not started, it keeps rotating for a certain time with the effect of moment of inertia it has on the starter pinion .
  • the starter pinion rotates and gets close to the flywheel ring gear; as a result deformation occurs on the starter pinion and flywheel ring gear during coupling. Since the starter pinion gets closer by rotating, it cannot settle directly inside a gap of the flywheel ring gear. The starter pinion rubs against the flywheel ring gear for a certain amount of time. The friction continues until the starter pinion coincides with the gap on the flywheel ring gear. When the starter pinion coincides with the gap, it continues moving forward and tries to rotate the flywheel ring gear.
  • a starter protection relay and a circuit which has a timer which waits for six seconds after a starting activity. After the vehicle is started , when an alternator steps in , it perceives that the vehicle is active and does not allow a second starting activity. Disadvantage of this system is that the alternator steps in after the engine is activated and does not allow the second starting process. However it does not provide any solution to the failure of starting off of the engine.

  • Another preferred embodiment of the invention comprises a chassis which is provided following a resistor. Accordingly, in the event that energy above normal values is received in the resistor, excessive energy is transm itted to the chassis.
  • Another preferred embodiment of the invention comprises a processor line which is provided between an accum ulator and a microprocessor. Accordingly, continuous energy is provided to a m icroprocessor for it to be able to operate.
  • a starter mechanism relates to an operating method. Said starter mechanism operates according to the following steps:

  • the microprocessor transmits, the energy received from the accumulator to the resistor through a relay line,
  • the resistor gains magnetic characteristics for a certain period of time and the key is brought to the open position thereby cutting off the ignition line.

  • the second arm of the relay line (44) is in contact with a chassis (43) departing from the resistor (421).
  • the information line (21) corresponds to the first position (411) on the microprocessor (41) while the ignition line (22) corresponds to the second position (412).
  • the ignition line (22) departs from the microprocessor (41) and is coupled with the key (422) and following said coupling it extends and reaches the starter motor (30).
  • an ignition switch (20) The operation of an ignition switch (20) is as follows. A user inserts the vehicle key in the ignition switch (20) and turns it to the first stage. At this point, energy coming from an accumulator (11) is transmitted to an information line (21). Then, the user continues the movement and turns the vehicle key. Thus, the user ensures that energy coming from the accumulator (11) is transmitted to an ignition line (22). When the user stops the turning force he applies on the vehicle key, the key returns to the first position. Therefore, it is ensured that energy coming from the accumulator (11) is retransmitted to the information line (21).

  • a microprocessor (41) senses that energy is at the first position (411), the vehicle is prepared for being operated, and the first energy is given to the system.
  • energy coming from the accumulator (11) is transmitted to an ignition line (22).

  • Transm ission of the energy from an accumulator ( 1 1 ) to a starter motor (30) is prevented .
  • I n the event that the user tries to start the engine again while the vehicle is active, since no energy can be transmitted from the accumulator ( 1 1 ) to the starter motor (30) , no deformation between the starter motor (30) pinion and the flywheel ring gear (50) can occur.
  • the second alternative situation is that a starter motor (30) cannot transm it sufficient drive to a flywheel ring gear (50) and a vehicle does not operate.
  • a starter motor (30) cannot transm it sufficient drive to a flywheel ring gear (50) and a vehicle does not operate.

  • the energy received from an accum ulator (1 1 ) is transmitted to a microprocessor (41 1 ) through an information line (21 ) .
  • This transmitted energy is transferred to a resistor (421 ) through a relay line (44) .
  • the resistor (421 ) gains magnetic characteristic by said energy for a certain amount of time.
  • the resistor (421 ) brings the key (422) to an open position.
  • Magnetic characteristic time of the resistor (421 ) includes rotation and stop time of a starter pinion with the effect of moment of inertia.
  • a microprocessor (41) decides to transmit the energy between the first position (411) and the second position (412). Accordingly, it provides energy transmission to a resistor (421) and a relay (42) is activated. For example, when a user sets a vehicle key from the start position to the first position (411), the microprocessor (41) does not transmit any energy to the resistor (421). Since the resistor (421) does not gain magnetic characteristic, it cannot get a key (422) opened and no disconnection occurs on an ignition line (22). When the user continues to turn the vehicle key, the microprocessor (41) senses that the second position (412) is reached.
  • the microprocessor (41) transmits the energy coming from an accumulator (11) to the resistor (421). As long as the user does not set the vehicle key to the starting position on the ignition switch, the microprocessor (41) continues transmitting the received energy to the resistor (421).
