Put, it is characterised in that：Including tabletting, holddown spring, electromagnetism pressing device and vehicle-mounted computer, the holddown spring is arranged at electronic
Two, machine is between carbon brush and tabletting, and the electromagnetism pressing device is arranged at the side that tabletting is connected with holddown spring, the electromagnetism
Pressing device controls to produce tabletting constant suction by vehicle-mounted computer, carbon brush constant pressure is pressed in commutator.
Further, the electromagnetism pressing device includes electromagnet and pressure sensor, and pressure sensor is arranged at tabletting
Between electromagnet, vehicle-mounted computer is passed to for detecting the pressure between carbon brush and commutator, and by detected value, it is described vehicle-mounted
Computer controls electromagnet to produce constant suction by controlling to flow through the size of electric current in electromagnet coil in real time, makes carbon brush constant pressure
It is pressed in commutator.
Further, the motor is series excitation brush motor.
Further, the electromagnet includes coil and armature.
Further, the end of described two carbon brush is respectively arranged with holddown spring, and two carbon brush are respectively by compressing bullet
Spring is symmetrically connected with two ends of tabletting, and the electromagnetism pressing device is arranged at the side that tabletting is connected with holddown spring, position
In the middle part of tabletting.
Compared with prior art, what the utility model possessed has the beneficial effect that：
Designed on two carbon brush of series-wound motor and a constant compressing control device is installed, it is ensured that carbon brush and commutation
Good contact between device.The device can make between carbon brush and commutator all the time as a result of carbon brush pressures cycle control system
Keep good contact；The effective rate of utilization of carbon brush is greatly improved, the effective rate of utilization 30% of carbon brush is improved；It can greatly prolong
Fault rate in the service life of starter, reduction vehicle starting system.
Brief description of the drawings
Fig. 1 is theory diagram of the present utility model.
It should be noted that for clearly attractive in appearance, coil and armature in constant-pressure control device in the block diagram drawing process
It has been drawn in the right side of tabletting.Actual constant-pressure control device should in figure tabletting left side, to maintain to produce suction to the left to tabletting
Power.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Automobile starter carbon brush constant-pressure control device as shown in Figure 1, it is characterised in that：Including tabletting 1, holddown spring 2,
Electromagnetism pressing device and vehicle-mounted computer（ECU）3, the holddown spring 2 is arranged between two carbon brush 4 of motor and tabletting 1, institute
State electromagnetism pressing device and be arranged at the side that tabletting 1 is connected with holddown spring 2, the electromagnetism pressing device passes through vehicle-mounted computer 3
Control produces constant suction to tabletting 1, the constant pressure of carbon brush 4 is pressed in commutator 5.
Further, the electromagnetism pressing device includes electromagnet 6 and pressure sensor 7, and the electromagnet includes coil
61 and armature 62, under electric current and armature 62 in coil 61 are acted on, produce the pressure to two carbon brush 4；Pressure sensor 7 is set
It is placed between tabletting 1 and electromagnet 6, for detecting the pressure between carbon brush 4 and commutator 5, and detected value is passed to vehicle-mounted
Computer 3, foundation is provided for the electric current in the control coil 61 of vehicle-mounted computer 3；The vehicle-mounted computer 3 flows through electromagnetism by controlling in real time
The size of electric current in iron coil 61, the pressure that regulation armature 62 is produced by tabletting 1 and holddown spring 2 to carbon brush 4, makes carbon brush 4
Constant pressure is pressed in commutator 5.
Further, the motor is series excitation brush motor.
