According to the requirement of QC/T 731-2005 " automobile is used the actuating motor technical conditions ", the stand endurancing has increased severity, and it is 35000 times by 30000 revisions that petrol engine uses the starter life-span.Before the test, place the variator gear neutral (or the clutch pedal support on earth) to cut off the transmission of power of engine and power train with wooden stick.Be contained in the element of device for testing durability of starting motor of automobile in the control box; Connect each element with the wiring requirement of power lead, and connect with starting system and the generator associated connections end in power supply bundle of lines test unit related elements and the instruction carriage by Fig. 2.Be set to S1 and S2 the cycling time of starting retaining control time relay 1; Be set to S2 and S1 the cycling time of ON retaining control time relay 3; The power-line plug of air switch 2 insert the test site～the 220V socket in; Press the air switch energized then, automobile starting motor durability test has just begun.
Its principle of work is:
1, actuating motor time control
Be set to S1 and S2 the cycling time of starting retaining control time relay 1; Do not switch on when the solenoid that the closed connection of air switch makes solenoid energising S1 → normally opened contact of starting retaining control time relay 1 break off S1 → A.C. contactor 7, actuating motor is not worked.Being recycled to S2 behind the time relay 1 energising S1 makes the closed S2 → normally opened contact of normally opened contact make the normally opened contact closure of solenoid energising S2 → second A.C. contactor 7 of second A.C. contactor 7 make the starting retaining end → actuating motor → battery terminal negative of normally closed contact → ignition switch connector of the normally opened contact → relay for automobile of battery positive voltage power supply in the instruction carriage → through ignition switch connector positive source retaining+→ the second A.C. contactor 7 make the actuating motor rotation of switching on.After this start and stop of controlling actuating motor by S1 that is provided with and S2 time constantly circulate.
2, ON retaining time control
Be set to S2 and S1 the cycling time of ON retaining control time relay 3, behind starting retaining control time relay 1 energising S1, be recycled to S2 and make the closed S2 of normally opened contact → by the closed S2 of normally opened contact of solenoid energising S2 → the 1st A.C. contactor of normally closed contact energising S2 → the 1st A.C. contactor 4 of solenoid energising S2 → ON retaining control time relay 3 of the ON retaining control time relay 3 of the normally opened contact control of starting retaining control time relay 1.When the 1st pair of normally opened contact of the 1st A.C. contactor 4 is closed, connect ON retaining circuit.Battery positive voltage+→ the 1st pair of normally opened contact → ON retaining → ECU → battery terminal negative of ignition switch connector positive source+→ the 1 A.C. contactor 4-circuit of fuel control system, injection system and firing system is connected; The normally closed contact that is recycled to S1 → time relay behind the ON retaining control time relay 3 energising S2 breaks off S1 breaks off the normally opened contact of the 1st A.C. contactor 4, cuts off ON retaining power supply.After this ON by S2 that is provided with and S1 time control ignition switch keeps off continuous break-make circulation.
3. relay for automobile control
Cut off the power supply of actuating motor with the L point control relay for automobile 6 of generator.The time of starting retaining control time relay 1 circulates in S2; Actuating motor starting is connected ON retaining power supply → engine start → generator for electricity generation → make relay for automobile solenoid energising → relay for automobile normally closed contact disconnection → cut-out actuating motor power supply through the L point by the ON retaining control time relay 3 of starting retaining control time relay 1 control simultaneously.Behind engine operation S2, ON retaining control time relay 3 is recycled to S1 → cut-out ON and keeps off power supply → engine stop working S1, and S3 is a not generating dutation of generator, and T-S3 is generator for electricity generation time (T is a cycle period each time).
4, actuating motor start-stop time control
Control actuating motor stop time with the L point of generator, the actuating motor running time is S3-S1.The actuating motor off-air time is that T-(S3-S1) T is a cycle period.
5, rolling counters forward control
Counter is electrically connected with the 2nd pair of normally opened contact of first A.C. contactor 4, the 2nd pair of every closure of normally opened contact of first A.C. contactor 4 once, rolling counters forward is once; The continuous stored count of counter in process of the test; After counting down to 35000 times, cut off the air switch power supply, off-test.
Fig. 3 is starting motor durability test sequential control figure.
A starts retaining time control timing
Can be known that by sequential chart according to starting retaining time control timing, be S1 and S2 the cycling time that starting retaining control time relay 1 is provided with, S1 is starting retaining trip time, and S2 keeps off turn-on time for starting;
B ON keeps off the time control timing
Can be known that by sequential chart according to ON retaining time control timing, be S1 and S2 the cycling time that ON retaining control time relay 3 is provided with, S1 is ON retaining trip time, and S2 is ON retaining turn-on time;
The control of C relay for automobile time
Can know by sequential chart; S3 is a not generating dutation of generator; T-S3 is the generator for electricity generation time, when generator one generating, cuts off the actuating motor circuit through generator L point and relay for automobile; When engine start makes generator for electricity generation instantaneous trip actuating motor circuit, play the safeguard protection effect of actuating motor;
The control of d actuating motor start-stop time
The start-stop time of actuating motor reality was controlled by the break-make electricity time of generator L point control relay for automobile; Selected relay for automobile plays a part the safeguard protection relay of actuating motor; So be S3-S1 the start-up time of actuating motor, the off-air time of actuating motor is S1.
