Abstract
The utility model discloses an improved automatic starting and stopping device of an automobile engine, which comprises a crankshaft, wherein the output end of the crankshaft is connected with a planet carrier in a planetary gear mechanism, and a sun gear of the planetary gear mechanism is connected with a permanent magnet rotor in a three-phase synchronous alternating current motor; the system also comprises an electronic control unit powered by a storage battery, wherein a first control end of the electronic control unit is in bidirectional communication connection with the three-phase synchronous alternating current motor, and a second control end of the electronic control unit is in bidirectional communication connection with other control units; the gear ring of the planetary gear mechanism is provided with a one-way clutch for performing one-way mechanical locking on the gear ring, namely only allowing the gear ring to rotate clockwise. The utility model discloses a one-way clutch control ring gear can make control speed faster, and control is simple, and the oil consumption and the exhaust emission that significantly reduce improve the economic nature of car, reduce and discharge pollution.
Description
Technical field
The utility model is related to a kind of improved automotive engine automatic start-stop devices.
Background technology
Traditional automobile engine does not have automatic start-stop function, and oil consumption and exhaust 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, complicated, of high cost；When an engine is stopped, can not
A certain cylinder nearby is made to be in suitable impulse stroke, the cylinder lights a fire and is not easy success when engine is again started up, and increases startup
The load of machine reduces the service life of starter motor.
Utility model content
The utility model aim is to provide a kind of improved automotive engine in view of the defects existing in the prior art to open automatically
Stop device.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of improved automotive engine opens automatically
Stop device, including bent axle, the planet carrier connection in the output terminal and planetary gear mechanism of the bent axle, the planetary gear mechanism
Sun gear connect with the p-m rotor in three-phase synchronous alternating current generator；The electronic control unit by storage battery power supply is further included,
First control terminal of the electronic control unit and three-phase synchronous alternating current generator two-way communication link, the second control terminal and other controls
Unit two-way communication link processed；The control output end of the electronic control unit is connect with hydraulic control unit；The planet tooth
It takes turns and is provided with to carry out gear ring unidirectional mechanical locking, the one-way clutch for only allowing gear ring clockwise on the gear ring of mechanism.
The beneficial effects of the utility model：(1) the utility model can make control fast using one-way clutch control gear ring
Degree faster, and controls simply, greatly reduces oil consumption and exhaust gas discharge, improves the economy of automobile, reduces exhaust emission；(2) row
Star gear mechanism is normal engaging structure, and when engine start does not have pause and transition in rhythm or melody sense, improves the ride comfort of automobile；(3) starter motor is adopted
With three-phase synchronous alternating current generator, there is better startability；(4) during engine stop, a certain cylinder nearby is made to be in suitable
Impulse stroke, the cylinder is lighted a fire successfully when engine is again started up, and alleviates the load of starter motor, extends the use of starter motor
Service life also makes engine be easier smoothly to start.
Description of the drawings
The operation principle schematic diagram of Fig. 1 the utility model.
Specific embodiment
Shown in Fig. 1, be related to a kind of improved automotive engine automatic start-stop device, including bent axle 1, the bent axle 1 it is defeated
Outlet is connect with the planet carrier 3 in planetary gear mechanism, sun gear 6 and the three-phase synchronous alternating current generator of the planetary gear mechanism
P-m rotor 7.1 in 7 connects；Further include the electronic control unit by storage battery power supply, the first of the electronic control unit
Control terminal and three-phase synchronous alternating current generator two-way communication link, the second control terminal and other control unit two-way communication links；Institute
It states and is provided with to carry out gear ring unidirectional mechanical locking, i.e. only clockwise unidirectional of permission gear ring on the gear ring of planetary gear mechanism
Clutch 2.Wherein, planetary gear mechanism is mainly made of planet carrier 3, gear ring 4, planetary gear 5 and sun gear 6.The three-phase
Synchronous AC motor 8 is mainly made of p-m rotor 7.1 and stator 7.2.
When running car encounters 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 made to be in suitable impulse stroke.When need to start to walk again, as long as driver loosens the brake, electronic control
The work of unit control three-phase synchronous alternating current generator, one-way clutch locking gear ring, certain cylinder in proper operation stroke are also lighted a fire
Work done makes engine start work jointly, and after engine start success, one-way clutch releases braking, into normal work shape
State, at this time planetary gear mechanism 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 above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
