Description
Technical field
The present invention relates to engine starter field, particularly a kind of bielectron switch starting machine and its control method.
Background technology
Starter on engine is mainly by the starter toothed wheel of motor and its output shaft end, electromagnetic switch and shift fork group
Into, when key door is closed, motor is started working, and electromagnetic switch, which is powered, drives shift fork starter toothed wheel is engaged with engine ring gear,
Starter toothed wheel after engagement on starter runs at high speed, and drives engine work.
This working method without any buffering of starter has some following deficiency：
1st, the high current of starting moment, which not only results in battery tension, reduces excessive, influences starting performance, and can be right
Battery causes damage.
2nd, starter toothed wheel is in not rotation status in starter toothed wheel and engine ring gear engagement process, and the state may
Cause the tooth of starter toothed wheel during engagement mutually to be hit with the tooth of engine ring gear and cause apical tooth, it is impossible to engage successfully.
3rd, starting moment, rotation has a torque peak to starter suddenly, makes starter and engine causes vibration simultaneously
Make a noise, starter and engine are caused damage, shorten the service life of starter and engine.
4th, electromagnetic switch will have two coils, be pull in winding and hold-in winding respectively.The effect of pull in winding is in key
Iron core is moved to electromagnetic switch with a high current (pulling electric current) initial stage that spoon door is connected and had and initial pull effect, it is ensured that starting
Gear can reliably be ejected and is meshed with engine ring gear.The effect of hold-in winding is when starter toothed wheel and engine ring gear can
Ejection state by maintaining starter toothed wheel after engagement with a less electric current (holding electric current).In general starter
Pull 6 times that electric current is often to maintain electric current.Because switch internal has two coils, weight is big, cost is high, coil windings are complicated
Degree is high, the fault rate of electromagnetic switch is high.
The content of the invention
The present invention is can to reduce battery decompression there is provided one kind to solve the problem of above-mentioned prior art is present, avoid
Apical tooth, reduction start noise and vibration, extension starter and the bielectron switch starting machine of service life of aeroengine and its control
Method.
The present invention technical solution be：A kind of bielectron switch starting machine, including motor and be connected to its output
Starter toothed wheel, electromagnetic switch and the shift fork of shaft end, it is characterized in that：The electromagnetic switch has single coil, this pair of electricity
Sub switch starter also includes ECU, sensor, the electronic switch A of size for controlling to flow through electromagnetic switch electric current and is used for
Control flows through the electronic switch B of the size of motor armature electric current；The electronic switch A connects with electromagnetic switch, electronic switch B
Connected with the armature circuit of motor, the power end of bielectron switch is parallel on the positive pole of battery, the control of bielectron switch
End processed is connected to ECU signal output part, and the output end of the sensor and ECU input are connected, and provide input to ECU
Signal, and popping one's head in for sensor is located at the side of starter toothed wheel, ECU another input is connected with key door, and by key door
Another input signal is provided to ECU, bielectron switch cooperates under control of the ecu completes the starter toothed wheel bullet of starter
Go out, the process of positive engagement and smooth start.
The control method of bielectron switch starting machine as described above, it is characterized in that：
1st, connect after key door, key door closure, electronic switch A is provided to electromagnetic switch in the presence of ECU and pulled electricity
Stream, makes starter toothed wheel reliably be ejected in the presence of electromagnetic switch and shift fork；
2nd, when sensor detect starter toothed wheel it is at a fully engaged after, electromagnetic switch A is pulled under ECU instruction by original
Electric current is reduced to the holding electric current that starter toothed wheel can only be kept to be in ejection state；
3rd, electronic switch B gives the 8%- of starter rated current under ECU instruction during starter toothed wheel ejection
14% low current, starter toothed wheel is slowly rotated during ejection, makes starter toothed wheel avoid apical tooth from showing with engine ring gear
As occurring and reaching flexible engagement, it is to avoid engagement is unsuccessful and reduces the impact caused to starter and engine；
4th, after starter toothed wheel and engine ring gear are at a fully engaged, signal is fed back to ECU by sensor, and electronic switch B is in ECU
Control under give starter by the low current gradually to the electric current of rated current × 100%, make starter toothed wheel by slowly turning
It is dynamic to ramp up rated speed, so as to drive engine work to operate.
Further, the holding electric current is the 1/5-1/7 for pulling electric current.
The beneficial effects of the invention are as follows：
1st, the electromagnetic switch of the bielectron switch starting machine only has single coil, in the presence of electronic switch A, Ke Yitong
Cross to be passed through and pull electric current and holding two kinds of electric currents of different sizes of electric current.The single coil in the presence of both different electric currents
Pulling, keeping two kinds of functions for prior art electromagnetic switch can be realized.
2nd, starter toothed wheel is slowly rotated during engagement is ejected with rated current 8%-14% operating current, is made
Starter toothed wheel is engaged with engine ring gear in rotation will not occur apical tooth phenomenon.
3rd, working speed gradually increases from low to high in whole starting process, flexible transition, starting torque without larger peak value,
Extend the service life of starter and engine.
4th, smoothly started due to being slow, battery is not in larger pressure drop.Rising for starter is not interfered with
Dynamic performance also will not produce damage to battery.
5th, the electromagnetic switch only one of which coil of the starter, alleviates weight, reduces cost, reduces answering for winding
Miscellaneous degree, the fault rate for reducing electromagnetic switch.
