As shown in Figure 1, the driving power generating system of the first embodiment, the load 50 that there is the power takeoff 20 be connected with the hunting gear 11 of power-transfer clutch 10, the power generation assembly 30 be connected with power takeoff 20, the transformation device 40 be connected with power generation assembly 30 and be connected with transformation device 40.
And this driving power generating system also has energy compensation system load 50 being carried out to energy compensating, energy compensation system has power supply 110, detecting device 120, control setup 130 and switching device 140.
Power supply 110 is to described load supply of electrical energy.Power supply 110 is connected with load 50 by switching device 140; Power supply 110 is connected with load 50 via switching device 140.Detecting device 120 is for judging whether power generation assembly 30 supplies to give enough electric energy to load 50.
Control setup 130 is connected with power supply 110 and detecting device 120, based on the output of detecting device 120, switching device 140 is controlled, when detecting device 120 is judged as that power generation assembly 30 does not supply enough electric energy to load 50, load 50 is communicated with power supply 110 by switching device 140 by control setup 130, power supply 110 is powered to load 50, power generation assembly 30 is judged as to load 50 for when giving enough electric energy at detecting device 120, control setup 130 is by switching device 140, the connection of disconnecting consumers 50 and power supply 110, stop powering from power supply 110 to load 50.
Specifically, as shown in Figure 1, detecting device 120 can be made up of the clutch operating sensor 121 detected the state of power-transfer clutch 10, when power-transfer clutch becomes released state from engagement state, be judged as that power generation assembly does not supply enough electric energy to load, when power-transfer clutch becomes engagement state from released state, be judged as power generation assembly to load for giving enough electric energy.
In addition, as shown in Figure 2, detecting device 120 can also be made up of the voltage comparator 122 detected the input voltage of load 50, when the input voltage of load is lower than preset value, be judged as that power generation assembly does not supply enough electric energy to load, when the input voltage of load is not less than preset value, be judged as power generation assembly to load for giving enough electric energy.
Control setup is according to detecting device testing result, make switch element opening and closing to realize the power supply to load and power-off, control setup can be made up of multiple circuit, and be mainly used in the switching controlling output circuit, commutation circuit can be made up of relay, electromagnetic switch etc.
According to above-mentioned driving power generating system, in the driving power generating system of the hunting gear power taking from power-transfer clutch, there is the energy compensation system compensated the electric power needed for load, this energy compensation system comprises power supply, switching device, detecting device and control setup, when the electric energy being judged as supplying load is not enough, close switch, by power supply, auxiliary power supply is carried out to load, even if thus when power-transfer clutch is stepped in chaufeur gearshift, the Power output of driving engine interrupts, the decline of power generation assembly generating quality, and when can not supply the electric energy needed for it to load, also can by the power supply in compensating device, enough electric energy are supplied to load, thus consumer and load can be made normally to work, consumer is avoided to damage.Thus solve the shifting power disruption existed from the driving power generating system of the hunting gear power taking of power-transfer clutch, its application is widened, applicability is stronger, and can utilize the hunting gear power taking from power-transfer clutch better, modification difficulty and the low advantage of cost.
In addition, when the acquisition of control signal mainly relies on as clutch operating sensor, control setup can comprise the latch function of signal, and when such power-transfer clutch continues separately, what energy compensation system can continue carries out complementary energy.In addition, when judging according to the input voltage of load, not only energy compensating can be carried out when disengaging of clutch, also energy compensating can be carried out to load at vehicle running state instability, electrical generator when sending electric energy instability.
In addition, as shown in Figure 3, power supply 110 can also be connected with power generation assembly 30 via switching device 140, the voltage of control setup to power supply detects, when the voltage of power supply is lower than its threshold value, by switching device, power supply is communicated with power generation assembly, by power generation assembly to power source charges.
Thus when the electric power of power supply is not enough, power supply becomes load, can be charged by power generation assembly to power supply, and in addition, charge circuit and transformation device separate and design by which, can reduce the complexity of transformation device circuit.
In addition, switching device can comprise the Variable flow control unit that can convert the electric energy of power supply and/or power generation assembly.As shown in the example of fig. 4, can comprise can according to the Variable flow control unit 141 needing to carry out electric energy two-way changing of consumer for switching device 140.The voltage of power supply or electric current can be made thus to become voltage needed for load or electric current, when the voltage of power generation assembly or electric current also can be made to become power source charges, the voltage that power supply can accept or electric current.Thus the stability of electric energy can be improved, make it better by load or application of power.
Certainly, when switching device is only connected with load, Variable flow control unit can for being only transformed to the Variable flow control unit of the single-phase conversion of the curtage needed for load by the curtage of power supply.
Main Function and the transformation device of Variable flow control unit are similar, and Variable flow control unit is connected with power supply, need thus to carry out charging and discharging to power supply.When to power source charges, power supply is equivalent to load here, and it needs to use stable electric energy, and needing with Variable flow control unit is thus the power supply voltage that can use or electric current by power generation assembly voltage or curent change.In addition, power supply also outwards discharges, if its sparking voltage and with electric load use rated voltage between there is gap, such as power line voltage 24V, but the voltage of load 48V, needing thus to change electric energy with Variable flow control unit, is 48V by the voltage transformation of power supply.
In addition, switching device can be connected with load and/or described power generation assembly indirectly via transformation device.As shown in the example of figure 5, the switching device 140 comprising Variable flow control unit 141 can be connected with load 50 and power generation assembly 30 via transformation device 40.Thus secondary power transformation can be carried out to the electric energy of power supply, thus can more stably supply to load, and the electric energy of power generation assembly is also carried out secondary power transformation, thus can more stably charge to power supply.
Be connected with transformation device by Variable flow control unit is because the electric energy that electrical generator sends has certain limit, such as 100V to 200V, and the design of transformation device may just according to this standard, each translation circuit be input as 100V to 200V, the input being less than 100V can not be utilized.In contrast, power supply is all generally 12V or 24V, if the electricity of power supply is input to transformation device, then need voltage to transform between 100V to 200V from 12V or 24V, this translation circuit is the main composition of Variable flow control unit.
Wherein, transformation device be that the electric energy of the instability sent by electrical generator becomes stable electric energy for load, it mainly comprises step-up/step-down circuit, can be made up of various ways, it is near a certain numerical value that object can realize exactly by power change, by low to a high-profile, by height to low-key.Also have one piece of mu balanced circuit afterwards, exactly the electric energy after change is stablized, be a steady state value, and filtering interfering, this mu balanced circuit also can be made up of various ways.
In addition, power supply is vehicle starting storage battery.As shown in the example of Figure 6, power supply can be vehicle starting storage battery 111.The design of energy compensation system charge circuit can be saved thus, and the purchasing of omitting external power supply, not only cost-saving and space, and make that the structure of energy compensation system is compacter, circuit is simpler.
In addition, each embodiment above-mentioned is only a kind of embodiment, and each embodiment above-mentioned combination in any can form various may connection, and this combination is also contained in protection scope of the present invention.
The object of this invention is to provide a kind of driving power generating system, hunting gear from power-transfer clutch is carried out to the driving power generating system of power taking, the power of interrupt delivery can be compensated when disengaging of clutch, vehicle-mounted consumer is made to obtain stable continual high-quality electric energy, applicability is stronger, and reduces modification difficulty and cost.
Above the driving power generating system of the preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-mentioned concrete embodiment, only otherwise depart from the scope of claim, can various distortion or change be carried out.Present invention resides in the various distortion in the scope of claim and change.
