Description
Technical field
The present invention relates to a kind of new automobile engine automatic start-stop device.
Background technology
Traditional automobile engine does not have automatic start-stop function, and its oil consumption and waste gas discharge are big, and exhaust emission is more, and passes
During the engine start of system, due to starter structural instability so that car body has pause and transition in rhythm or melody sense, reduces the ride comfort of automobile；
Traditional automobile current generator is typically all to be provided separately with starter motor, and complicated, cost is high；When an engine is stopped, can not
A certain cylinder nearby is set to be in suitable impulse stroke, the cylinder is lighted a fire and is not easy success when engine is again started up, and adds startup
The load of machine, reduce the service life of starter motor.
The content of the invention
The defects of the present invention seeks to exist for prior art, provides a kind of new automobile engine automatic start-stop device.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of new automobile engine automatic start-stop device,
Including bent axle, the planet carrier connection in the output end and planetary gears of the bent axle, the sun of the planetary gears
Wheel is connected with the p-m rotor in three-phase synchronous alternating current generator；Also include the electronic control unit by storage battery power supply, the electricity
First control terminal of sub-control unit and three-phase synchronous alternating current generator two-way communication link, the second control terminal and other control units
Two-way communication link；The control output end of the electronic control unit is connected with hydraulic control unit；The hydraulic control unit
Control output end be connected with for the liquid braking device braked to the gear ring in planetary gears.
Beneficial effects of the present invention：(1) generator of the present invention is integrated with starter motor, simplifies structure, reduces cost,
Greatly reduce oil consumption and waste gas discharge, improve the economy of automobile, reduce exhaust emission；(2) planetary gears is often engagement
Structure, there is no pause and transition in rhythm or melody sense during engine start, improve the ride comfort of automobile；(3) generator is integrated with starter motor, is simplified
Structure, reduce cost；(4) during engine stop, a certain cylinder nearby is made to be in suitable impulse stroke, engine opens again
The cylinder is lighted a fire successfully when dynamic, is alleviated the load of starter motor, is extended the service life of starter motor, also makes engine easily suitable
Profit starts.
Brief description of the drawings
The operation principle schematic diagram of Fig. 1 present invention.
Embodiment
Shown in Fig. 1, it is related to a kind of new automobile engine automatic start-stop device, including bent axle 1, the output of the bent axle 1
End is connected with the planet carrier 3 in planetary gears, sun gear 6 and the three-phase synchronous alternating current generator 7 of the planetary gears
In p-m rotor 7.1 connect；Also include the electronic control unit by storage battery power supply, the first control of the electronic control unit
End processed and three-phase synchronous alternating current generator two-way communication link, the second control terminal and other control unit two-way communication links；It is described
The control output end of electronic control unit is connected with hydraulic control unit；The control output end of the hydraulic control unit is with being used for
The liquid braking device 2 braked to the gear ring 4 in planetary gears connects.Wherein, above-mentioned planetary gears mainly by
Planet carrier 3, gear ring 4, planetary gear 5 and sun gear 6 are formed.The three-phase synchronous alternating current generator 8 is mainly by the He of p-m rotor 7.1
Stator 7.2 is formed.
During automobile normal running, electronic control unit control hydraulic control unit combines hydraulic clutch, bent axle driving
Planetary gears drives p-m rotor to rotate, and three-phase synchronous alternating current generator is in generator operation state, passes through Electronic Control
Unit rectification charges a battery.
When running car runs into red light or traffic congestion, do not turning on the aircondition and accumulator electric-quantity, brake vacuum, engine water temperature are equal
When reaching normal value, driver's brake pedal, control system meeting automatically controlled engine stops working, and burnout time point is just
A certain cylinder nearby is set to be in suitable impulse stroke.When need to start to walk again, as long as driver loosens the brake, Electronic Control
Unit control three-phase synchronous alternating current generator works while controls hydraulic control unit to brake liquid braking device, in suitable work
Certain cylinder for making stroke is also lighted a fire work done, engine start is worked jointly, and after engine start success, liquid braking device releases system
It is dynamic, into normal operating conditions, now planetary gears idle running.
When opening at least one of air-conditioning or accumulator electric-quantity, brake vacuum, engine water temperature not up to normal value, start
Machine automatic start-stop device, which will not automatically control, starts of ancient India stop working.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
