The specific embodiment
Further specify concrete structure of the present invention, working process and embodiment below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 are a kind of complete layout with a kind of embodiment of integrated vehicle of mobile power station and special purpose, it is at the flywheel place of driving engine one power takeoff 7 to be set, be provided with change-gear set 6 between power takeoff 7 and flywheel, this power takeoff is installed on the output shaft of change-gear set 6.Link to each other with high-pressure oil pump 2 by open type friction lining 8.Power hydraulic system and engine position are below the compartment.
Fig. 3 is another kind of embodiment of the present invention, and this embodiment installs a power taking cliding gear 12 on two of engine mission.The imput shaft 9 of the power driven change speed gear box 4 of driving engine 1 is passed to constant mesh gear 11 by driving gear 10 with power, when needs generate electricity, cliding gear 12 is meshed with constant mesh gear 11, and power will flow to high-pressure oil pump 2 by plunging joint 13; When not needing to generate electricity, cliding gear 12 and constant mesh gear 11 are separated, high-pressure oil pump 2 is not worked.
Fig. 4 represents that HM Hydraulic Motor 14 is by shaft coupling 15 and electrical generator 16 connection structure scheme drawings.
Fig. 5 a, Fig. 5 b, Fig. 5 c express three kinds of different power hydraulic systems that the present invention adopts.This power hydraulic system mainly is made up of high-pressure oil pump 2, individual event valve 19, pilot overflow valve 22, the logical governor valves 21 of Electromagnetic Drive two, HM Hydraulic Motor 14, fuel tank 17, fil 18 accumulators 20 and the connecting line that have an aperture position transduser.Hydraulic oil enters high-pressure oil pump 2 from fuel tank 17 through fil 18, and pressure is brought up to certain level.High pressure oil, thereby is realized the control of the fluid flow of process HM Hydraulic Motor 14 is realized the control to HM Hydraulic Motor 14 rotating speeds by the action of pilot overflow valve 22 and Electromagnetic Drive two logical governor valves 21 by behind the individual event valve 19 under the regulation and control of electronic control unit.By coupler 15, HM Hydraulic Motor 14 links to each other with electrical generator 16, thus the final control that realizes electrical generator 16 rotating speeds.Energy storage 20 works to reduce the fluid pressure fluctuation in high tension loop.
First kind (shown in Fig. 5 a) can conveniently realize the parking electricity generate function.Its Electromagnetic Drive two logical governor valves 21 are in parallel with HM Hydraulic Motor 14, and Electromagnetic Drive two logical governor valve 21 control bypass oil masses can be controlled the fluid pressure in the pressure duct, reduce the consumption of power of high-pressure oil pump 2.Simultaneously, under dead ship condition, because the rotating speed of driving engine 1 can be by automatically controlled flexible dynamic system free adjustment, flow by HM Hydraulic Motor 14 can be realized by the pump oil mass that the rotating speed of regulating driving engine 1 is promptly regulated high-pressure oil pump 2, can reduce the bypass oil mass as much as possible like this, reduce the expenditure of energy of electric-control motor 1, improve commercial efficiency.
Second kind (shown in Fig. 5 b) can not only conveniently realize the generating of stopping, and more can conveniently realize the electricity generate function of driving a vehicle.Its Electromagnetic Drive two logical governor valves 21 are connected with HM Hydraulic Motor 14, and Electromagnetic Drive two logical governor valve 21 direct controls are by the oil mass of HM Hydraulic Motor 14.When automobile is in driving states, the degree of cyclic irregularity of electric-control motor 1 is very big, and the high pressure oil mass that HM Hydraulic Motor 14 needs is relatively fixing, by the oil mass of Electromagnetic Drive two logical governor valve 21 direct controls by HM Hydraulic Motor 14, can conveniently realize the electricity generate function of driving a vehicle.But the interior hydraulic fluid pressure of high-pressure oil passage this moment determines that by pilot overflow valve 22 stress level is higher, the energy that makes high-pressure oil pump 2 consume is more, the energy of electric-control motor 1 consumption simultaneously is more, and commercial efficiency is not as first kind of loop, but the motion of vehicle is convenient flexibly.
The third (shown in Fig. 5 c) can conveniently realize stopping and generate electricity and the driving electricity generate function, is the comprehensive of first and second kinds of loops.By selecting to be arranged on three switches on the high-pressure oil passage, can realize that Electromagnetic Drive two logical governor valves 21 and HM Hydraulic Motor 14 are in parallel or be connected in series.When only needing the parking electricity generate function, open switch 23,25, off switch 24 adopts parallel way can reduce the consumption of power of system, improves economy; In the time will realizing the driving generating, open switch 24, off switch 23,25, the employing series system can conveniently be realized the control to generator speed, guarantees power generating quality.
The working process that the present invention realizes is as follows:
When Special Purpose Vehicle needs electric energy, open type friction lining 8 and power takeoff 7 are fitted tightly (perhaps with power taking cliding gear 12 and constant mesh gear 11 engagements) by joystick, and the mode enable switch that will be arranged on automobile cab is threaded to generating operation mode, can select the to drive a vehicle generating or the generating of stopping.When choosing the parking generating, ECU (Electrical Control Unit) enters the parking power generation mode, uniting of the switch position regulates the control that realizes electrical generator 16 rotating speeds by what the rotating speed and the Electromagnetic Drive two of electric-control motor 1 were led to governor valves 21.This moment, the rotating speed of electric-control motor 1 was directly regulated by electronic control unit, and automobile accelerator pedal lost efficacy.When choosing when generating driving, ECU (Electrical Control Unit) enters the driving power generation mode, realizes control to electrical generator 20 rotating speeds by the quick adjustment to the switch position of Electromagnetic Drive two logical governor valves 13.During automobile was in and travels at this moment, the rotating speed of electric-control motor 1 was determined that by actual condition automobile accelerator pedal is effective.After adopting hydraulic transmission mode, the rotating speed of electric-control motor and the rotating speed of electrical generator are separate, realize its transitive relation by fluid flow.
Embodiment:
In the actual verification test: the existing commercialization electrical generator of selecting for use is that rating horsepower is the synchronous brushless alternator of 40kW, its performance perameter is: rated speed of rotation 1500r/min, rated current 72.2A, power factor 0.8, output voltage 400V, frequency 50Hz, the mode of employing harmonic excitation, and DTW5 type voltage regulator is housed, relative regulation is ± 2.5%.Select for use the band power takeoff existing commercialization driving engine, its rating horsepower is 147kW, the speed ratio of change-gear set 6 is 1: 1.14, optimum oil consumption point near 1700r/min, its length=720 * 540 * 620mm
