Description
Technical field
The invention belongs to motor car engine annex manufacturing technology field, specifically, relate to a kind of automobile starter motor.
Background technique
At present, in motor car engine annex manufacturing technology field, specifically refer to automobile starter component manufacturing technology field.Starter motor is again motor, and it is mechanical energy with the electric energy conversion of storage battery, drives the startup that the engine flywheel rotation realizes motor.
As everyone knows, the starting of motor car engine needs the support of external force, and automobile starter is being played the part of this role exactly.Taking it by and large, starter motor is realized whole starting process with three parts, and direct current motor is introduced from the electric current of storage battery and made the actuation gear of starter motor produce mechanical motion; Driving mechanism engages into flywheel ring gear with actuation gear, can automatically throw off after engine start simultaneously; The break-make of starter circuit capable is then controlled by a magnetic switch.Wherein, motor is the critical piece of starter motor inside, its working principle be exactly we in junior physics, touch take the conversion process of energy of Ampere law as the basis, i.e. electrical conductor stressed effect in magnetic field.Motor comprises the necessary parts such as armature, commutator, magnetic pole, brush, bearing and shell.Motor must rotate by external force before turning round with self power.Motor is transitioned into the process that can turn round voluntarily by external force by state of rest, is called the starting of motor.The start mode that motor is commonly used has manpower starting, auxiliary gasoline starting and three kinds of forms of electric starting.Manpower starting adopts rope to draw or hand mode, and is simple but inconvenient, and labor intensity is large, is only applicable to some low power motors, on some automobiles only in support mode keeping; Auxiliary gasoline starting mainly is used on the powerful diesel engine; The electric starting mode is easy and simple to handle, and starting rapidly has the re-lighting ability, and can distant control, is therefore extensively adopted by Hyundai Motor.
During existing automobile starter work, electric current is connected to the starter motor carbon brush from battery positive voltage through starter relay, makes armature obtain electric energy and rotation.Conventional passenger car starter motor in the start-up course, starts the loop current peak value and reaches about 600A-800A, and stabling current is near 300A.As the short time duty motor, if starter motor repeatedly frequently uses, or starting time is long, copper cash bonding in the starter motor over-heat inside, armature, and loop current increases sharply.If it is untimely that cut off the power supply for this moment, circuit or starter motor can produce naked light, can cause the car load spontaneous combustion when serious.In the existing starter motor fus is not installed, starter motor itself can not auto-breaking, usually brings potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is, owing in the existing starter motor fus is not installed, starter motor itself can not auto-breaking, if starter motor repeatedly frequently uses, or starting time is long, the starter motor over-heat inside, copper cash bonding in the armature, loop current increases sharply.If it is untimely that cut off the power supply for this moment, circuit or starter motor can produce naked light, can cause the car load spontaneous combustion when serious, will lead to major accident when serious, and a kind of automobile starter motor is provided.
Technical conceive of the present invention is, automobile starter motor of the prior art, it starts loop fus is not installed, thus when needing starter motor itself to have short circuit, when working long hours the function that can cut off the power supply; For addressing this problem, on the brush pigtail that the present invention is connected, increase the Metal Melting part between starter relay and carbon brush holder, by specific sectional shape, restriction starts the loop and passes through the time by electric current and electric current.Thereby can prevent starter motor because of internal short-circuit or work long hours and in time to cut off the power supply, result in greater loss.Use this scheme can increase the Security of start-up system.
Technological scheme provided by the present invention is, a kind of automobile starter motor comprises starter circuit capable, magnetic switch and motor, and described magnetic switch links to each other with described motor, is provided with overtemperature protection system between described magnetic switch and the motor.
Starter motor comprises that also carbon brush holder and brush distinguish that described carbon brush holder is distinguished with described magnetic switch by brush and is connected.
Described overtemperature protection system is arranged on described brush and distinguishes, the starter motor electric current is by described overtemperature protection system.
Described overtemperature protection system is a fus, and described fus comprises the Metal Melting part; When starter motor is worked, there is electric current to pass through on the described Metal Melting part.
Described Metal Melting part has the sectional shape of ladder-type, is provided with fuse link current limliting groove in the described Metal Melting part.
The time length that the size of current that described fuse link current limliting groove restriction starter motor startup loop is passed through and electric current pass through.
Adopt technological scheme provided by the present invention, can effectively solve technical problem to be solved by this invention is, owing in the existing starter motor fus is not installed, starter motor itself can not auto-breaking, if starter motor repeatedly frequently uses, or starting time is long, the starter motor over-heat inside, copper cash bonding in the armature, loop current increases sharply.The characteristics such as if it is untimely that cut off the power supply for this moment, circuit or starter motor can produce naked light, can cause the car load spontaneous combustion when serious, will lead to the technical problems such as major accident when serious, and simultaneously, technological scheme provided by the present invention has low cost of manufacture, and performance safety is reliable.
