Description
Technical field
The present invention relates to a kind of 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 automobile engine automatic start-stop device.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of 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 gear of the planetary gears with
P-m rotor connection in three-phase synchronous alternating current generator；Also include the electronic control unit by storage battery power supply, the electronics control
First control terminal of unit processed and three-phase synchronous alternating current generator two-way communication link, the second control terminal and other control units are two-way
Communication connection；The control output end of the electronic control unit is connected with hydraulic control unit；The of the hydraulic control unit
One control output end is connected with the liquid braking device for being braked to the gear ring in planetary gears, the second control output
Hold and be connected with the hydraulic clutch for carrying out clutch with gear ring to the sun gear in planetary gears
Beneficial effects of the present invention：(1) present invention is integrated with starter motor, is simplified structure, is reduced cost, subtract significantly
Few oil consumption and waste gas discharge, improve the economy of automobile, reduce exhaust emission；(2) planetary gears is normal engaging structure, hair
Motivation does not have pause and transition in rhythm or melody sense when starting, and improves the ride comfort of automobile；(3) generator is integrated with starter motor, simplifies structure, drop
Low cost；(4) starter motor uses three-phase synchronous alternating current generator, has more preferable startability；(5) during engine stop, make
A certain cylinder nearby is in suitable impulse stroke, and the cylinder is lighted a fire successfully when engine is again started up, and alleviates the negative of starter motor
Lotus, extends the service life of starter motor, also makes engine be easier smoothly to start.
Brief description of the drawings
The operation principle schematic diagram of Fig. 1 present invention.
Embodiment
Shown in Fig. 1, be related to a kind of automobile engine automatic start-stop device, including bent axle 1, the output end of the bent axle 1 with
Planet carrier 3 in planetary gears connects, in the sun gear 6 and three-phase synchronous alternating current generator 8 of the planetary gears
P-m rotor 8.1 connects；Also include the electronic control unit by storage battery power supply, the first control terminal of the electronic control unit
With three-phase synchronous alternating current generator two-way communication link, the second control terminal and other control unit two-way communication links；The electronics
The control output end of control unit is connected with hydraulic control unit；First 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, and the second control output end is with being used for planet tooth
The hydraulic clutch 7 that sun gear 6 in wheel mechanism carries out clutch with gear ring 4 is connected.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 8.1
Stator 8.2 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, and now liquid braking device is not braking.
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 work while control hydraulic control unit to brake liquid braking device, now hydraulic pressure from
Clutch separates, and three-phase synchronous alternating current generator driving engine makes certain cylinder in proper operation stroke light a fire, and makes engine ignition
Success, after engine start success, three-phase synchronous alternating current generator switchs to power generation operation state, and liquid braking device releases braking, liquid
Clutch is pressed to combine.
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.
