Basic functional principle
The adjusting control of Hydraulic Pump and HM Hydraulic Motor
The adjusting control of the 2 pairs of Hydraulic Pumps of the present utility model and HM Hydraulic Motor describes with reference to the accompanying drawings.
The diesel oil-liquid-electricity series hybrid-power car that the utility model proposes is adjusted system according to Hydraulic Pump and HM Hydraulic Motor load characteristic curve, adopt permanent moment of torsion and permanent power to make that accessory drives is that mode of operation is always permanent torque drive, the foundation of permanent power of system and permanent moment of torsion can be with reference to shown in Figure 2, wherein M is the moment of torsion of HM Hydraulic Motor, N is the horsepower output of oil pump, ω is the rotating speed of HM Hydraulic Motor, ω
1Be the rotating speed (being generally constant) of variable capacity oil pump, q1 is the discharge capacity of variable capacity oil pump, and q2 is the discharge capacity of HM Hydraulic Motor.
Wherein if ignore HM Hydraulic Motor, the mechanical loss of hydraulic actuating cylinder and the loss of pressure of pipeline, the moment of torsion M=pq2 of HM Hydraulic Motor, wherein p is the pressure of controllable capacity pump output, if load one is regularly, it be a certain amount of, so when q2 was constant, system became permanent torque condition.
The horsepower output N=pq1 ω 1 of controllable capacity pump is if wish that as long as controllable capacity pump is output as permanent power the discharge capacity q1 of control variable oil pump.From the characteristic curve of Fig. 2 as can be seen, when operation pressure is constant, the rotational speed omega that needs HM Hydraulic Motor, can be divided into two stages to finish when the highest adjusting from minimum.
(1) the discharge capacity q2 with HM Hydraulic Motor is transferred to maximum q2max, and is fixed on this numerical value; Regulating q1 has minimum value to increase gradually to maxim q1max, and at this moment the rotational speed omega of HM Hydraulic Motor is also from minimum value ω
MmRaise gradually, till the discharge capacity of oil pump reached maximum, ω rose to ω '. and in the speed regulation process in this stage, the output torque M of HM Hydraulic Motor is constant, and the power N of oil pump output increases gradually, becomes permanent moment of torsion speed governing.Its scope is shown in Fig. 2 left-half.
(2) the variable capacity of pump is transferred to maxim q1max after, again that this value is fixing, it reduces gradually from original q2max during the discharge capacity of regulator solution pressure motor then, at this moment the rotating speed of HM Hydraulic Motor just raises gradually from ω ', the output torque M of HM Hydraulic Motor increases and reduces gradually with rotational speed omega, and the horsepower output N of oil pump maintenance is constant, becomes speed control by constant power, and its scope is shown in Fig. 2 right half part.
The relation of the speed of vehicle ' and Hydraulic Pump and motor
For forming open-circuit system by volume adjustable hydraulic pump and HM Hydraulic Motor, so long as change the hydraulic pressure capacity of pump, the discharge capacity of fixed hydraulic motor just is the permanent moment of torsion output of HM Hydraulic Motor operating mode naturally.And changing the HM Hydraulic Motor discharge capacity, the fixed hydraulic pump capacity then is the permanent power output of a HM Hydraulic Motor operating mode.In the driving process of vehicle, be generally permanent moment of torsion operating mode during low speed driving, be generally permanent power operating mode when running at high speed, form permanent moment of torsion, permanent power by volume adjustable hydraulic pump in the Full Vehicle System and variable hydraulic motor.When importing by the amplifier of potentiometer regulated variable Hydraulic Pump control displacement variation, the hydraulic pressure capacity of pump changes, and the discharge capacity of HM Hydraulic Motor is constant at this moment, thereby makes HM Hydraulic Motor be output as permanent moment of torsion, and also both drive wheels is output as permanent moment of torsion.In general, vehicle is when low rate start, and the running state of car is the permanent moment of torsion of low speed, so the permanent torque characteristics of the low speed of this Full Vehicle System is used when the low speed of car, meets the low speed driving state of car.When controlling the amplifier of displacement variation with potentiometer regulated variable HM Hydraulic Motor, the discharge capacity of HM Hydraulic Motor changes, and the discharge capacity of HM Hydraulic Motor changes, and this moment, the hydraulic pressure capacity of pump was constant.Thereby make HM Hydraulic Motor be output as permanent power.In general, vehicle is when running at high speed, and the running state of car is the permanent power of high speed, so the high speed constant output characteristic of this Full Vehicle System uses when the running at high speed of car, meets the high-speed travel state of car.
The operating mode of characteristic pattern is divided
Start at car and to begin and 20 kilometers/hour left and right sides low speed segments use permanent moment of torsion operating mode.The speed of a motor vehicle high with 20 kilometers/hour after, use permanent power operating mode to 80 kilometers/hour speed periods.For a perpendicular line is arranged on the characteristic pattern abscissa, the left side of this line is regulated for the controllable capacity pump discharge capacity, and this left field is permanent moment of torsion output area.The right side of this line is regulated for the variable-dis-placement motor discharge capacity, and this right side area is permanent power output area.
The implementation procedure of permanent power of system and permanent moment of torsion
Permanent power of system and permanent moment of torsion operating mode must require artificial control to realize according to driving, two electric controllers that can change discharge capacity of Hydraulic Pump and HM Hydraulic Motor are arranged, system's upper computer collects the voltage of pedal when depressing, and control which electric controller work according to this magnitude of voltage by calculating of upper computer.Then, this voltage is delivered to the electric controller that needs work.Such as, pedal is depressed 2 volts of voltages of output, if 2 volts of cooresponding speed of a motor vehicle of voltage are 15 kilometers/hour, upper computer then can be to the electric controller output voltage of Hydraulic Pump after judging, it is 15 kilometers/hour discharge capacity that Hydraulic Pump then changes to discharge capacity the speed of a motor vehicle, realizes permanent moment of torsion operating mode.If pedal is depressed 4 volts of voltages of output, suppose that 4 volts of cooresponding speed of a motor vehicle of voltage are 65 kilometers/hour, then can be after upper computer is judged to the electric controller output voltage of HM Hydraulic Motor, it is 65 kilometers/hour discharge capacity that HM Hydraulic Motor then changes to discharge capacity the speed of a motor vehicle, realizes permanent power operating mode.Various vehicle conditions have control 12 to detect in real time under automatic compensation feature power rating, and corresponding control strategies instruction (accurate permanent moment of torsion and accurate permanent power that this strategy is realized by electronic circuit) is provided.
The utility model is because accessory drives is that mode of operation is always permanent torque drive, so the regular variation of the discharge current of electrokinetic cell.
Can simplify the index and the price of the frequency converter that the complexity of frequency converter both reduced for this reason.
Use permanent moment of torsion and permanent power advantage as follows:
(1) uses motor band volume adjustable hydraulic pump during permanent moment of torsion, can reduce oil consumption and zero-emission function.
(2) use variable hydraulic motor during permanent power, can keep engine operation in best operating point and zone by actv..
(3) compare with hybrid-power electric vehicle, overall system machine design and layout are simple and convenient, the functional reliability height, and complete vehicle weight is low.

The car load operational process is described
Process 1: start-up course
When car load started, controller 12 started frequency converters 11 by Oil Switch 14, and controlled battery pack 13 and rotate by cable 29 driving motors 16, and modulated pressure controll block 36 is in the energy release position.Described electrical motor 16 drives 15 work of second Hydraulic Pump again, and the pressure of these second Hydraulic Pump, 15 outputs and flow drive HM Hydraulic Motor 4 and rotate, and change the discharge capacity of second Hydraulic Pump 15 and HM Hydraulic Motor 4, can change its car drive torque and speed.When hydraulic system pressure reached the safe pressure of setting, second by pass valve 17 was opened, and plays safety effect.Identical with hybrid-power electric vehicle, when starting, use by car load electrical motor 16 to start.Thereby this car can guarantee the cold start-up function, has reached the zero-emission of driving engine 8 when cold start-up.
Process 2: after the startup
After car load starts, controller 12 is judged travel certain distance or reach certain speed (also can by the hand-operated forced start the engine 8 that requires) of power cars, just can be by controller 12 control battery pack 13, and start frequency converter 11 by 10 rotations of cable 28 drive alternator for vehicle, the rotation of this alternator for vehicle 10 drives belt pulley 9 start the engines 8 and rotates, this driving engine 8 drives first Hydraulic Pump 7, the first-class valve 6 of described first Hydraulic Pump, 7 one sides can all be opened earlier, make hydraulic oil pass through this valve off-load, driving engine 8 reaches zero load startup.In this process, process 1 will continue continuous firing.
Process 3: do not have acceleration and climbing and travel
Garage finishes after the low speed accelerating sections, when finishing cruising work by controller 12 notice driving engines 8, if this moment, road conditions were smooth, controller 12 will make 15 off-loads of second Hydraulic Pump or the manually unloading that is driven by electrical motor 16, frequency converter 11 and electrical motor 16 are quit work, the first hydraulic pressure by pass valve 6 is closed, only by 7 work of first Hydraulic Pump, and make driving engine 8 be operated in best operating point or district, at this moment, because the first hydraulic pressure by pass valve 6 is closed, first Hydraulic Pump 7 drives HM Hydraulic Motor 4 work through oil pipe 20, the discharge capacity that changes first Hydraulic Pumps 7 or HM Hydraulic Motor 4 by controller 12 can change the moving velocity of car, and the accumulation of energy situation modulated pressure controll block 36 that this moment, controller 12 was looked hydraulic accumulator 37 is in energy release position or energy closed condition.The combination of this first Hydraulic Pump 7 and HM Hydraulic Motor 4 can guarantee that engine operation is at best operating point or district (referring to Fig. 2) by actv..
Process 4: dump energy management
When controller 12 judges that driving engine 8 is when best operating point has surplus power to battery pack 13 chargings, controller 12 starts frequency converter 11 makes alternator for vehicle 10 work by cable 28, under driving engine 8 drives, electrical generator 10 is to battery pack 13 chargings, simultaneously, driving engine 8 also drives first Hydraulic Pump 7 and works on.
Process 5: hydraulic energy retrieval management
This car has the water brake energy recycle device.At the import of HM Hydraulic Motor be installed in series integrated controll block 36 of hydraulic pressure and small-sized hydraulic energy storage 37.This device has energy recovery and energy release function.
Energy recovery function is: when brake, all hydraulic pump stop control lever, because the inertia of car, car continues to travel, the integrated controll block 36 of hydraulic pressure is in energy recovery state, and wheel drives backteeth bag 2 and drives change speed gear box 34 through deceleration transmission device 3, and change speed gear box drives HM Hydraulic Motor 4, the outlet of HM Hydraulic Motor 4 is from the fuel tank oil suction, and the fluid of HM Hydraulic Motor 4 imports flows to small-sized hydraulic energy storage 37 by the integrated controll block 36 of hydraulic pressure.To its stored energy.Hydraulically-controlled one- way valve 5 and 18 plays the effect that flows to Hydraulic Pump 7 and 15 by the fluid of HM Hydraulic Motor.Make the fluid of HM Hydraulic Motor 4 can only flow to small-sized hydraulic energy storage 37.
Process 6: auxiliary energy control
Use the energy content of battery when starting except power car, during full power acceleration work, driving engine 8 and electrical motor 16 drive first Hydraulic Pump 7 and 15 work of second Hydraulic Pump simultaneously respectively, and the power drive of double pump HM Hydraulic Motor 4 under the max.cap. situation is finished the upward slope of vehicle or given it the gun.
Because electrical motor 16 is as auxiliary power, so the amount of monomer of battery pack 13 and quality can be less, the 25%-35% of the shared approximately total transmission system power of the energy content of battery that the utility model adopts.Therefore the own wt of this car is purer electrically operated in light weight.Therefore the power of accessory drives system can be done smallerly, and it is power design that the power of main transmission deducts accessory drives according to the actual maximum drive power of car.The work purpose of accessory drives system is to finish the power-assisted of the Daheng of the cold start-up of car and demand moment of torsion.Accessory drives system will be the basic assurance of native system maximum discharge requirement, high oil-saving effect, and the power young pathbreaker of accessory drives system reduces the cost of Full Vehicle System.
Power car in the process of moving can be by the power of driving engine 8, drives A/C, power steering and the work of other ancillary apparatus, makes to drive and take more comfortable.Because the high power density of Hydraulic Elements, because the power of accessory drives system is less, and native system is compared with the series hybrid-power battery-driven car, the total quality of car will be very low again.
Compare with the series hybrid-power battery-driven car, for main transmission, the employed diesel motor 8 of native system is directly used in machinery and hydraulic pressure 7,4 transmissions, the energy of driving engine 8 directly is converted to the mechanical energy that powered vehicle is travelled through hydraulic pressure 7,4 driving systems, and driving efficiency can reach 80%.Thereby employing diesel powerplant or turbine generation unit have been avoided, also need not be converted to electric power again, at present on international and domestic market, costing an arm and a leg of diesel powerplant and turbine generation unit, therefore we can say that native system has high driving efficiency and low transmission cost, technical also more more ripe than diesel powerplant.
For the accessory drives system that uses battery pack 13 and electrical motor 16 to drive, because the Hydraulic Pump that requires is to work under the rotating speed deciding, make and adopt the frequency converter 11 of AC induction motor to become very simple, when accessory drives is work, the incoming frequency of frequency converter 11 is always a constant, need not control the input of frequency converter 11 again, thereby reduce the requirement of frequency converter 11, its small size and low price are achieved.Again because the incoming frequency of frequency converter 11 is constant, therefore make the well-regulated variation of discharge current of power battery pack 13, this will make the real-time dynamic management to battery pack 13 become more easy.In a word, this technical scheme will make accessory drives system become simple in structure, and reliable operation is with low cost.
Except that battery pack as the auxiliary energy, the energy of small-sized hydraulic energy storage also plays the effect of auxiliary energy.And release energy prior to battery pack, this energy can discharge under the two states mode:
1, (usually at the vehicle cold start) during the Hydraulic Pump stop control lever
When car starts, engine idle, all hydraulic pump stop control lever, controller 12 judges that battery pack 13 and the integrated controll block 36 of hydraulic pressure are in the energy release position, if have in the hydraulic accumulator this moment energy to exist to store in the hydraulic accumulator then fluid to flow to the import of HM Hydraulic Motor 4 by the integrated controll block 36 of hydraulic pressure, HM Hydraulic Motor 4 presses bag 2 powered vehicle to travel by change speed gear box 3 and back.The fluid of HM Hydraulic Motor outlet flows back to fuel tank 33.Hydraulically-controlled one- way valve 5 and 8 plays the effect that fluid in hydraulic accumulator flows to Hydraulic Pump 7 and 15.
2, (when normal vehicle is travelled) during the Hydraulic Pump fuel feeding
During normal vehicle operation, engine operation, the Hydraulic Pump fuel feeding, the integrated controll block 36 of hydraulic pressure is in the energy release position, if when having in the hydraulic accumulator this moment energy to exist then in hydraulic accumulator, to store fluid to flow to the import of HM Hydraulic Motor 4 by the integrated controll block 36 of hydraulic pressure, Hydraulic Pump 7 and 15 fluid also can flow to the import (or only have in two Hydraulic Pumps) of HM Hydraulic Motor, and HM Hydraulic Motor presses the bag powered vehicle to travel by change speed gear box and back.The fluid of HM Hydraulic Motor outlet flows back to fuel tank.Hydraulically-controlled one- way valve 5 and 8 conductings under the effect of Hydraulic Pump 7 and 15.The fluid that guarantees Hydraulic Pump 7 and 15 flows to HM Hydraulic Motor 4.
Under the help of accessory drives system, the main transmission most of the time is operated on driving engine 8 best operating points or the zone, therefore effectively raises the discharge index and the oil-saving effect of car.
Because the utility model adopts electrical motor as auxiliary power, its work purpose is to finish the power-assisted of the Daheng of the cold start-up of car and demand moment of torsion.Accessory drives system is the basic assurance of native system maximum discharge requirement, high oil-saving effect, and the power young pathbreaker of accessory drives system reduces the cost of Full Vehicle System.
Compare with the series hybrid-power battery-driven car, for main transmission, the employed diesel motor of native system is directly used in machinery and hydrostatic drive, the energy of driving engine directly is converted to the mechanical energy that powered vehicle is travelled through power hydraulic system, thereby avoided employing diesel powerplant or turbine generation unit, also need not be converted to electric power again.
For using battery and motor-driven accessory drives system, because the Hydraulic Pump that requires is to work under the rotating speed deciding, make and adopt the frequency converter of AC induction motor to become very simple, when accessory drives is work, the incoming frequency of frequency converter is always a constant, need not control the input of frequency converter again, thereby the requirement that has reduced frequency converter is achieved its small size and low price.Again because the incoming frequency of frequency converter is constant, therefore make the well-regulated variation of discharge current of electrokinetic cell, this will make the real-time dynamic management to battery become more easy.For the energy recycle device that uses,, reclaim the energy that produces because of drag and can save a large amount of energy because city transportation often needs frequently to stop or start.
Under the help of accessory drives system, the main transmission most of the time is operated on driving engine best operating point or the zone, therefore effectively raises the discharge index and the oil-saving effect of car.
Because the utility model adopts permanent moment of torsion and permanent power to make that accessory drives is that mode of operation is always permanent torque drive, can simplify the complexity of frequency converter, the index of the frequency converter of reduction and price.And, use the motor drives volume adjustable hydraulic pump during permanent moment of torsion, can reduce oil consumption and zero-emission, use variable hydraulic motor during permanent power, can keep engine operation in best operating point and zone by actv..
Only the above, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to the conspicuous variation that design of the present utility model extended out or change and still are among the protection domain of the present utility model.
