Application process is as follows:
1, when being in descending when vehicle maybe needing to slow down in operational process, gently step on the control pedal 1 in Fig. 1, make that depression bar 3 is descending to be between the first stroke (length when the braking valve rod comes downwards to back oil road 32 and will be closed from free state), press projection 2 this moment, the bar 78 that presses in Fig. 8 is depressed into to the right and makes normal tripping sheet 79 closed connections and state that normal combined pressure sheet 84 disconnects, electric oil pump 6 work, depression bar 3 presses the push rod 25 descending interlocks of braking valve rod 34 in Fig. 2 simultaneously, 28 compressions of pressure spring I are pressed on spool 29 on valve body 22, produce oil pressure in oil circuit and enter in the chamber of 45 of oil cylinder I 44 in Fig. 5 and Fig. 6 and piston rod I, pushing piston moves, make pushing tow dish 46, backup bearing 47, pushing tow bearing 48, press spring base 49, stage clip 50, platen 51, platen friction lining 52 is the mobile electrical generator driven friction 53 that presses to thereupon, the drive generator amature rotates, when producing electric energy to brake resistance of vehicle.Originally because the positive pressure between the stage clip 50 little platen friction linings 52 of the little oil circuit pressure of amount of compression and electrical generator driven friction 53 is also little, rotating speed is asynchronous, may there be relative sliding between the two, increasing along with line amplitude under pedal, stage clip 50 amount of compressions increase, in oil circuit, oil pressure increases, and when the friction coefficient between positive pressure and friction face long-pending was more than or equal to the electrical generator rotary resistance between the two, both just synchronously rotated.
Meanwhile because disconnecting the firing circuit and the oil supply circuit that make driving engine, normal combined pressure sheet 84 in Fig. 8 disconnects, engine off, driving engine is driven by vehicle inertia or sliding force and is rotated further, it is a kind of passive transport, still drive attached parts as turn to, lubricate, body cooling, air-conditioning etc. keep mode of operation, also make simultaneously engine cooling, lubricate, get rid of the refuse waste gas in combustion chamber, also give brake resistance of vehicle.
But the general meet requirements that slows down under above operating mode.
When lower long slope, the initial speed of a motor vehicle is slow, and braking force is also little, the sliding force of vehicle is greater than resistance, vehicle is in acceleration mode, and along with the increase of the speed of a motor vehicle, the electrical generator output power also increases, the passive rotating speed of driving engine also increases, also increase both for the resistance of vehicle, the sliding force due to vehicle on certain slope is certain thereupon, when its resistance increment when equating with sliding force, the vehicle motion that will remain a constant speed provides stable electric power to be used for deposit simultaneously.In electric oil pump 6 pump oil processes, increasing along with depression bar 3 descending amounts, when in oil circuit, oil pressure increases to certain value (shown in assurance Fig. 5, Fig. 6 of experiment setting, the oil pressure of relative sliding does not occur for platen friction lining 52, the electrical generator driven friction 53 of generator clutch) when the electrical generator Maximum Power Output, with the oil pressure switch 19 that backs down in Fig. 1, allow electric oil pump 6 quit work, check valve 20 closed-loops of electric oil pump 6 outlets, keep certain oil pressure in the loop, make by control piece maintenance work state.When pressure diminished, circuit was connected, and motor-drive pump 6 recovers pump oil.
In the first descending stroke section of depression bar 3, although braking valve rod 34 is also descending, can not connect the drg oil circuit.Vehicle braking force is mainly driving engine and electrical generator 15 both resistance sums.
2, when vehicle need to continue to slow down or stop, step on strength and the amplitude of the control pedal 1 in Fig. 1 under increasing, make depression bar be advanced into for 3 times between the second stroke, except above operating mode works on, the closed upper part back oil road 32 of braking valve rod 34 in Fig. 2-Fig. 4, valve rod annular groove 39 is connected brake activation valve oil input channel 40 and deceleration method standpipe interface 38 simultaneously, pressure oil enters by oil pipe that in Fig. 7 drg jack cylinder II 73, pushing piston bar II 71 moves through pressure spring II 68, brake body 66 is pressed in brake plate 65 on brake disc 63, thereby realize further deceleration or the parking of vehicle.
3, when vehicle needs emergency braking, step on fast control pedal, above the 1st step operating mode does not almost also have brake action, directly completes fast the 2nd step operating mode, and this is identical with the traditional braking operating mode.
4, in the braking procedure of Vehicle Driving Cycle, the speed of a motor vehicle is decreased to when not needing to brake, loosen the brake 1, in Fig. 1 under the effect of the screen resilience of return spring III 16, depression bar 3 upwards promotes the push rod 25 that drives simultaneously in Fig. 2-Fig. 4, ram seat 26, oil sealing 27 and braking valve rod 34 rise, when control pedal 1 release speed slow, when it rises to the first stroke section, owing to braking valve rod 34 with 40 sealings of brake activation valve oil input channel and with brake activation valve standpipe interface 38 and back oil road 32 UNICOMs, pressure disappearance in drg jack cylinder II 73 in Fig. 7, return spring II 67 will drive brake body 66 brake plate 65 will be moved right, the drg braking is removed, simultaneously partial pressure oil is squeezed covering oil storage kettle 7, get back to initial position until reach balance.in this process due to the rising of the push rod 25 in Fig. 2-Fig. 4, ram seat 26, oil sealing 27, pressure spring I 28 is upheld, generator clutch oil cylinder I 44 working oil path pressure reduce gradually, the oil pressure that the oil pump pump comes greater than pressure valve press pressure the time, pressure oil is pushed spool 29 releases of pressure open, when being totally released in rear oil duct oil pressure, control pedal 1 reduces to minimum, pushing tow dish 46, backup bearing 47, pushing tow bearing 48, press spring base 49, stage clip 50, platen 51, platen friction lining 52 is got back to initial position under the effect of return spring I 57 and return sheet 58, after pressing simultaneously projection 2 rises to the inclined-plane with depression bar 3 upper edge and the wheel trolley line of centers in leaving Fig. 8 being concordant, pressing bar 7 is moved to the left under the effect of normal pressure spring 85, normal tripping sheet 79 leaves, electric oil pump 6 quits work, and normal combined pressure sheet 84 closes up, motor circuit and oil circuit are resumed work, as long as vehicle does not stop fully, driving engine just can start voluntarily and resume work, continue to provide power that vehicle is accelerated.
5, when lower-speed state used braking and need driving engine not flame-out, the hand switch 21 of pressing in Fig. 1 got final product.
Be provided with pressure spring II 68 be provided with power-transfer clutch stage clip 50 and Fig. 7 drg in Fig. 5 of system, Fig. 6 generator clutch in, its objective is and slow down that in impact, many wheel brakings, pressure oil can prevent sideslip by automatic adjustment, but in order to make response time short as far as possible, so spring ratio should be larger.
In system due between generator clutch driven friction 53 and platen friction lining 52 and drg brake plate 65 and brake disc 63 gaps very little (only several millimeters), can realize fast clutch and braking when adopting suitable jack, only need very little motor-drive pump to meet the demands.
The existing chargeable battery 11 of circuit part in Fig. 1 system schematic has again electrolytic cell 18, be to discharge greater than capacity of cell owing to tending to potential energy to occur in Vehicle Driving Cycle, and vehicle self consumption of current is little, so just need to consider to increase energy storage device.But oil and electricity hybrid vehicle can reduce this part equipment with filling with just putting.
Indication energy-absorbing electrical generator of the present invention is that dynamo generator or alternating current generator could be connected with other electrical equipments by accompanying drawing after rectification is direct current (DC).
