Car brakeing vibration reclaiming scrap with measurable loading

A kind of car brakeing vibrational energy reclaiming scrap particularly utilizes car brakeing vibrational energy reclaiming scrap liquid and energy storage and that can be used to survey dead-weight capacity.

The vehicle reclaiming scrap of using in the world all is the braking energy reclaiming scrap at present, and does not have the vibrational energy regenerative apparatus.Above-mentioned braking energy reclaiming scrap roughly comprises following several types: (1). the flywheel-type regenerative brake; (2). can become inertia the regenerative brake of air pressure energy; (3). can become inertia the regenerative brake of electric energy; (4). can become inertia the regenerative brake of hydraulic pressure energy.But first kind, the flywheel volume is big, weight is big, and energy-saving efficiency is low; Second kind, need baroque air compressor; The third needs special large-capacity battery, electrical generator and electrical motor; The 4th kind of device be than first and second kind efficient height, and be simpler, in light weight than the third making, cost is low.French Patent (FRP) FR2332460 is the hydraulic pressure energy-storing-type.Two of mainly being separated by energy storage, hydraulic control clutch of this device vary in size and four sensors changing with the variable-displacement oil motor of wheel mechanical attachment, quantitative oil pump, transmission power, pressure and an actual displacement and baroque logic circuit component, five control oil cylinders, three solenoid directional control valves, three formed with the proportional pressure-type element of voltage signal and some other elements, lean on the foot feed energy storage; But this apparatus structure complexity, common brake still plays a major role during the braking beginning, cause the part inertia kinetic energy to lose in vain again by the friction lining heat release, efficient is lower, cost is high, vibrational energy in the vehicle ' can not be recycled, more can not be used for measuring weight and each wheel gravity distribution condition thereof of lade.

Task of the present invention provides a kind of novel hydraulic energy brake vibration reclaiming scrap, and it not only can become hydraulic pressure to braking energy can store utilization, and can recycle energy of vibration.Simple in structure, cost is low, mainly is that standard component is formed, and is easy to manufacture, easy to operate, energy-saving efficiency is high, it is mild that car brakeing is slowed down, the pollution of waste gas and NOISE ON ENVIRONMENT when reducing starting.Can also improve the load-carrying capacity of vehicle, self-measuring vehicle load tonnage.

The present invention be achieved in that the most basic composition of vehicle regenerative braking device comprise by clutch component control and and wheel between the variable capacity oil pump that the quantitative hydraulic oil motor of mechanical connecting relation arranged, maybe can use as motor.Here said fixed displacement oil motor can be gear oil motor or plunger-type quantitative oil motor.Variable capacity oil pump is connected with hydraulic accumulator with plunger type variable capacity pump or vane type controllable capacity pump, being controlled in the process of storing and releasing energy of their controlled elements.

Above said clutch component, can be its moving plate and the power-transfer clutch of transmission shaft, the railroad vehicle dynamical axis links with carrying axle, still is connected with oil motor electromagnetic type, hydraulic control or Pneumatic-control type; Also can adopt the brake shoe brake cheek that has removed friction lining in the drum brake mechanism and one group of small-sized oil motor is installed; Can also be one and be subjected to hydraulic pressure or air pressure control can compress and leave outer surface of tire, equally also be equipped with the support that moves back and forth of one group of small-sized oil motor.Above-mentioned several clutch component, by the joint of power-transfer clutch with separate, brake shoe brake cheek open with contraction, traversing carriage compress and leave just can be so that connection of the mechanical attachment between oil motor and wheel and cut-out.

Above said mechanical attachment mode, can adopt modes such as gear, sprocket wheel, friction wheel transmission that the axle that is rotating in power-transfer clutch moving plate and the vehicle is connected; Also can adopt and when brake shoe brake cheek opens, the oil motor drive wheel can be pushed mutually with the brake wheel inside face and with the rill that equates at interval or fine and closely woven pointed tooth is meshed or the connecting mode of friction wheel transmission; Can also be movable stand when compressing outer surface of tire, the oil motor drive wheel that outside face is wrapped with high coefficient of friction material pushes mutually with tire, to form the connecting mode of friction wheel transmission.

The common feature of above-mentioned mechanical attachment is: when car retardation travels, mechanical attachment is connected, oil motor is when oil pump usefulness, the low pressure oil of oil inlet being become high pressure oil under wheel drives discharges from oil outlet and is transported to the energy storage by change-over valve, this moment, oil motor was to do the resisting moment running for wheel, and whole process can be described as energy storage topping up process.When vehicle gave it the gun, mechanical attachment was also connected, and for the commutation of fixed displacement oil motor change-over valve, the high pressure oil in the energy storage flows into from oil inlet, and the low pressure oil of oil outlet flows back to fuel tank again; For variable capacity oil pump, change-over valve can commutate, and the mode during still by topping up is connected, but this moment oil pump must be under pneumatic or the control of surging with its offset or leaning angle by on the occasion of becoming negative value, high pressure oil is flowed into from oil outlet, oil inlet flows out.In a word, oil motor in this process or variable capacity oil pump are being done the kinetic moment running, and vehicle is play a part to promote to advance, and we can be referred to as to release can the tapping process.When vehicle at the uniform velocity travels, neutral slides or be in when stopping to travel, its mechanical attachment mode is cut off, and oil motor is in the transfixion state, and change-over valve also cuts off the path between itself and energy storage.

The simplest regenerative braking device has a common fixed displacement oil motor or a variable capacity oil pump, a three position four-way directional control valve can make the automatic pressure control valve that separates of clutch component with one when tapping stops, for example pressure relay or sequence valve are equipped with and can realize that change-over valve moves, clutch component leaves and the control element that engages.Simple pointer formula differential pressure gauge or other differential pressure type control element and pressure relay through repacking for example cited below.The defective of above-mentioned simple mechanism is, can not be according to vehicle heavy duty and underloading, correspondingly increase with low-tach variation at a high speed or reduce its applied moment, and the effective measures that remedy this defective are to increase element on this basis.

We can adopt one or more groups motor component, every group comprises two fixed displacement oil motor or one three gear motors that parameter is identical, connect when parallel connection during with its low pressure, high pressure, and have along with braking or when starting required moment increase, the control element that the motor component group number of working can be increased successively.This control element can be mounted in the one or more travel switches below the pedal and successively thereby the switch pressing be controlled corresponding motor component group and worked along with moving down of pedal, also can adopt with the rod member bonded assembly and can connect in turn the valve element of multiple sets of motors work or the control element of other type.For realizing respectively organizing the connecting mode of motor component series, parallel, between all motor component groups and energy storage, also be serially connected with a three position four-way directional control valve and a two-position four way change valve, and can cause the pressure relay of the automatic conversion of mode of operation and the control element of other form, for example: simple pointer formula differential pressure gauge or other differential pressure type control element that mention below through repacking.

For the torque peak of controlling mechanical coupling components with prevent hydraulic system leakage, between energy storage and fuel tank, be connected with the by pass valve of safety effect and played the hydraulic control one-way valve of pressurize effect.

Also can include in this energy reclaiming scrap and energy of vibration is changed into hydraulic pressure can be stored to vibrational energy regenerative apparatus in the energy storage.This device has to be installed in and singly goes out rod oil cylinder and directional control valve between floor underframe for vehicle and the axletree.

Between former fuel oil diaphragm pump of vehicle and fuel oil filter, being connected with one can realize turning down throttle so that the bi-bit bi-pass change-over valve of fuel-economizing and a flow regulating valve in the automatic tapping state of vibration energy storage.

In the delivery conduit after each vibrational energy regenerative apparatus converges, be serially connected with a 3-position-3-way change-over valve, in minute oil circuit and have and to measure each and singly go out the rod oil cylinder internal pressure, demonstrate each wheel gravity distribution condition, thereby can measure the pressure gravity table of the actual pay load of vehicle.

This energy reclaiming scrap can all reclaim energy of the brake inertia in the vehicle ' and energy of vibration, and is used when quickening starting or going up a slope.Its energy-saving effect is considerable.For example: 8.5 tons of common two-door bus's car weights, (30 kilometers/hour of initial velocity) every stopping-down once had the energy of 270 kilojoules can supply to store approximately when neutral slided, when system total efficiency was got minimum 0.64, the energy that this system is emitted when starting also was equivalent to 17.1 and restrains the energy that is produced behind the gasoline combustions.And passenger vehicle (400 meters meters) burns gasoline 73 gram only between two station boards, therefore, in 400 meters only braking once just can say approx that the energy-saving efficiency of this system is 23.3%.Because urban transit bus mostly is radial type, its weight is mostly more than 14 tons, as 17.74 tons of TJ661 gross weights, and 14.5 tons of BK651 gross weights, SK670S ₁26.7 tons of gross weights, 23.4 tons of CQ670 gross weights.If whole nation city motor bus aviation value is during by 14 tons of calculating (be 8.5 tons 1.76 times), but then during 30 kilometers/hour of the speed of a motor vehicle every brake snub once just fuel-economizing 17.1 * 1.76 ≈ 30 grams/time, even if 30 kilometers of speed out of reachs, (V reduces by 1/6 to get V=25 kilometer/hour, kinetic energy reduces by 11/36, less than 1/3).20 grams/time calculating is all pressed in fuel-economizing, and work in 1 year 320 days was travelled 8 hours every day, but then fuel-economizing (25 * 10 in a year ³* 8)/400 * 20 * 320=3.2 * 10 ⁶(gram)=3.2 ton/year.Suppose that the whole nation has 100,000, all load onto 320,000 tons of fuel-economizings in back a year, be worth more than 300,000,000 yuan.

The energy-saving benefit of vibrational energy regenerative apparatus is also very remarkable.If singly go out rod oil cylinder is to change system into reference to the bumper parameter on the liberation CA-10B car, if the vehicle body free frequency is 120 times/minute, mean value of amplitude is 8mm, whenever travel in the normal liquid-filled state so and just can import 12.06 rising pressure fluid to energy storage in 2.5 minutes, it is that 25 liters of initial pressures are 110kg/cm that these fluid can make a capacity ²Energy storage pressure be elevated to 212.5kg/cm ²If its efficient that is transformed into kinetic energy is 0.8, then fluid is all emitted the kinetic energy that produced of the back 15 gram energy that gasoline produced that are equivalent to burn, fuel-economizing reaches 8%.

Analyze from the regenerative braking device installation site again.Because the radius of brake wheel is the 4/10-5/10 of whole radius of wheel, just be equivalent to apply 200 kilograms braking force at the brake wheel place so apply 100 kilograms braking force at surface of tyre.In fact, existing drum brake mechanism generally all can be wheel lockup when emergency braking, bears whole braking forces and suffers the tire that is still wheel of severe wear.Its transmission shaft of vehicle of general automobile one class and the speed ratio between wheel that is to say the lock torque that just has been equivalent to apply 9.28 kilogram-metres at the lock torque that applies 1 kilogram-metre on the transmission shaft on axletree up to 9.28.As seen, connect oil motor than connect oil motor braking effect height on brake shoe brake cheek on surface of tyre and transmission shaft, the geomery of used element is also little.But,, then be that the permissible value at brake wheel place is the highest when the higher limit of considering the permission transfer torque and the joint stiffness of mechanical attachment mode.As seen, the regenerative braking device installation site must specifically be treated.For railroad vehicle, owing to seldom emergency braking occurs, get final product so only need on its dynamical axis or carrying axle to install as clutch component with power-transfer clutch; The transmission shaft of vehicle and trailer expose to(for) the various vehicular traffics with transmission shaft and nothing, consider that installation oil motor braking effect is poor on brake shoe brake cheek, and all remove the difficult for the moment acceptance of friction lining people, so, every have a vehicle that exposes transmission shaft, will based on transmission shaft with the mounting means of power-transfer clutch as clutch component.The torque peak of motor will be lower than the moment of torsion that transmission shaft can allow.In the side of wheel tyre the support that moves back and forth that has oil motor is installed again on this basis.The oil motor of two or more groups can be installed on each wheel.When further increasing moment again, two brake shoe brake cheek in the same brake wheel are staggered opening time, on the brake shoe brake cheek of formerly working oil motor is installed, keep friction lining on the brake shoe brake cheek of back work.If all load onto motor on two brake shoe brake cheek, just can all realize friction-free braking.The vibrational energy regenerative apparatus can replace the bumper on the former vehicle and installs in its position.

Below in conjunction with embodiment and accompanying drawing, concrete structure of the present invention is described in further detail.

Referring to Fig. 5, bead (37) both can adopt the bead part transformation of the way on the former transmission shaft, also can be individually as a sleeve class from workpieces, install and be fastened on the dynamical axis or carrying axle of locomotive, as long as vehicle to run its just rotate.When magnetic clutch (11) no power, part (37) dallies together by the moving plate that tangential key (36) are driving gear (13), (12) terminal pad (44) and (11); When (11) switch on, its moving plate and still adhesive, thus part (11), adapter shaft (40), sleeve (46) and oil motor (10) and (14) are connected as one rotation.Supporting plate (38) is to guarantee that tumbler has the support body of relative tram with support (41), (45).Transmission clutch part, oil motor or variable capacity oil pump all are contained on the support body, the axle that is rotating with vehicle when linking an end of this support body can rotate around the axis, the other end is suspended on the vehicle frame by fork (43), at the two ends of fork a connection seat (42) is housed respectively, one of them is fastened on the vehicle frame, another is fastened on the supporting plate (38), when part (37) is done any direction micro-mobile with transmission shaft, fork is also correspondingly done the swing of any direction trace, can not influence the correct transmission position of each tumbler at all.Should guarantee also that from installing fork (43) only bears pulling force, the turning to of part (37) (from big end) is that its installation site is as shown in Figure 5 when rotating for clockwise direction, if conter clockwise is when turning to, must be with the installation site among Fig. 5 around part (37) Rotate 180 °.If can produce three gear motors shown in Figure 6, with regard to available one three gear motor, replace part (10), (14), (45), (46) among Fig. 5, (40) also can make its corresponding simplified.The angle of the B face of fork (43) and supporting plate (38) generally between 5 °-30 °, it to the supporting plate both sides because the moment of torsion that gravity unbalance caused plays counteracting.Guard shield (39) can prevent dust and the splendid attire lubricating oil.

Braking energy reclaiming scrap mode of operation has 14 kinds, narrated respectively according to its structure below,

(1). attitude to be filled: in this state, hydraulic accumulator (26) tapping just finishes, and the vehicle retaining of having started to walk to hang up has possessed certain speed, enters the cruising state.Electromagnet 1DT, 2DT, 3DT and part (11) the magnetic clutch DLM of solenoid directional control valve among Fig. 1 (17), (18) all is in off-position, eight little intermediate relay 1J-8J in the circuit also are in off-position, two storage batterys of 12 volts are connected between the two poles of the earth of dynamo generator, can charge simultaneously.Part in the oil circuit (23) is to be formed by a simple pointer formula differential pressure gauge transformation of the way, zero-bit and pendulum back, left side institute position contacting at its pointer respectively add a contact, draw lead, 3J and 4J in the junction circuit, and on pointer shaft, draw a lead, junction circuit positive pole.At this moment, its pointer is in zero-bit.Also available other differential pressure type control elements of yk3 replace.Two pressure relay yk1 and yk2 all are in the open position in the diagram.Part (a 13) drivening piece (12) also connects by part (44) and the moving plate of power-transfer clutch dallies together, and motor is not worked.

(2). low pressure topping up state: at this moment, vehicle is changed over to this by cruising and installs brake snub.When the driver lifts Das Gaspedal, move down the HA switch, click the button 1QA on the change speed gear box bar handle again, send signal.Or do not remove the HA switch down, right crus of diaphragm is moved on on the brake pedal, press the button JZA on the pedal surface gently, pedal did not move down, there is no friction between friction lining and the brake wheel and take place this moment, but can send same electric signal yet, made relay 1J energising, its three moving closes, two break contacts play a role, greensignal light LXD follows the energising of 1J bright always, magnet coil 2DT, 3DT and power-transfer clutch energising, and brake lamp ZXD is bright.Two 12 volts storage battery becomes series connection by parallel connection, to satisfy the load voltage value of each electromagnet and magnetic clutch.If the generator output voltage of vehicle and battery tension are 24 volts or each element load voltage value when being 12 volts, just do not need this series connected conversion that become in parallel.

After said elements action and the adhesive, the driver does not need to jam on brake pedal downwards, just can make car retardation.At this moment, the driver also can hang neutral and makes vehicle slide deceleration.In addition, the mercury formula descending switch (51) and the mercury formula upward slope switch (55) of the automatic time delay control that can realize that descending topping up energy storage, upward slope release energy also are housed in control circuit, each switch all is to be charged into an amount of mercury and constituted by two thick one thin three sections glass tubes, also has electrode contact.When the level road smooth-ride, extra heavy pipe and road surface in vertical state, tubule parallels with the road surface and is basic identical with the installation aspect of chassis side rail.So-called automatic time delay control, be exactly because difference thick, the tubule footpath is bigger, mercury flows into another extra heavy pipe and rises to certain altitude from an extra heavy pipe, need one period delay time, when as long as vehicle is no more than this section delay time by short sloping road required time, mercury switch is just inoperative, to prevent unnecessary deceleration and acceleration.So, have only when the gradient on descending slope road and length reach certain value, mercury switch (51) just can be connected relay 1J automatically, realizes low pressure topping up state, with the increase of control descending speed.Simultaneously, the path that switch (55) has also cut off 2J makes duplex button (55), (54) malfunctioning, guarantees can not discharge the hydraulic pressure energy in the descending way.

In this state, the inertia kinetic energy of vehicle rotates by the gear motor that gear (13), (12) and power-transfer clutch (11) drive two works " oil pump " usefulness, makes kinetic energy change the hydraulic pressure energy into.The oil inlet O of two motors ₁, O ₂All connect oil outlet P with fuel tank (19) ₁, P ₂All communicate with energy storage (26) through (17), (18) and flow regulating valve (22), two motors in parallel are to the energy storage topping up, and its topping up flow is two motor delivery rate sums.Flow through check valve (15), (8) of the leakage flow of motor (14), (10) got back to oil inlet O respectively ₁, O ₂, in all topping up states of motor participation work, all be this flow direction.

(3). high pressure topping up state: along with the carrying out of topping up, the pressure of part (26) constantly rises, differential pressure gauge (23) is as long as there is liquid to flow into (producing difference of pressure at part (22) two ends) to part (26), its pointer is swing left just, thereby send electric signal, make the 4J energising in the circuit, three moving together contact of 4J are connected, the pressure relay yk2 of low pressure values is action immediately behind the beginning topping up, and its operating pressure value exceeds 3-4kg/cm than the preliminary filling nitrogen pressure value of energy storage ²Get final product.When the pressure in the part (26) was elevated near gear motor top pressure rated value, relay yk1 action was sent electric signal and is made the 3DT outage.Other element keeps low pressure without exception, mode of operation during topping up.At this moment, from the low pressure oil of fuel tank (19) O from part (14) ₁Mouthful flow into, after the supercharging from P ₁Mouth flows out, and enters the O of part (10) again ₂Mouth carries out boosting the second time, at last from P ₂Mouth flows out (26) and carries out the high pressure topping up, and at this moment two gear motors are in series, and the pressure that each motor bore is half of energy storage pressure, and delivery rate is the flow of a motor.Part (21) by pass valve plays the safety guard-safeguard effect to oil circuit, makes the pressure in (26) be elevated to just no longer continuation rising of certain numerical value.

(4). stop the topping up state: when the resisting moment that is subjected to oil motor when vehicle finally stops, topping up to part (26) also just stops, the pressure reduction at yk3 two ends disappears, pointer returns zero-bit from movable pendulum, send electric signal, make the 3J energising in the circuit, its moving together contact and two break contacts play a role, make 2DT and DLM outage, high-voltage oil liquid just is closed in (26), though (18), (21) and other element leakage is all arranged inevitably, but because part (18) has been blocked in the existence of hydraulic control one-way valve (27), (21) outlet of leakage flow, the O of part (14) ₁Mouth is to be connected with fuel tank in laststate, (27) can not opened for the moment, so (27) can play certain pressurize effect.

In addition, because the needs of special occasions, slide when vehicle is transferred to neutral by brake snub, transfer to by deceleration travel at a slow speed and the vehicle descending after when running into level road and at the uniform velocity travel, at this moment only need press deceleration energy storage ahead relieving button (60), or right crus of diaphragm is lifted away from the brake pedal surface, though this moment, vehicle still was among the operation, that realizes 3J energising, 2DT and DLM outage stops the topping up state in the same old way.It should be noted that press (60) or be lifted away from brake pedal after, slow down once more as making vehicle, just must jam on brake pedal downwards, 3JA one is connected when moving slightly at pedal.And allow anything but to adopt to press 1QA once more or right crus of diaphragm is moved on to Das Gaspedal to get on to press the JYA button.

(5). high pressure tapping state: when being in the vehicle that stops the topping up state and need starting to walk or quicken, just can press 1QA for the second time, perhaps jam on the JyA on Das Gaspedal surface gently, this moment, Das Gaspedal did not move down, throttle does not strengthen, but because the connection of JyA also can be sent electric signal, make the 2J energising in the circuit, its four moving together contact and two break contacts play a role, 3J is cut off the power supply, 1J, 1DT and DLM energising, at this moment high-voltage oil liquid is emitted from part (26), flows into the O of (14) through part (22), (18) ₁Mouthful, from P ₁Mouth flows out, and flows into O through part (17) again ₂Mouthful, at last from P ₂Mouth flows out to fuel tank.Though the flow direction unanimity during with the high pressure topping up is from O ₁What mouth flowed into is high-voltage oil liquid, from P ₂What mouthful flow out is low pressure fluid, opposite during with topping up on the force value size.At this moment, part in the oil circuit (10), (14) can be transformed into kinetic energy with the hydraulic pressure in the part (26), and are delivered to by part (11), (12), (13) that the promotion vehicle advances on the transmission shaft.

Not ugly working as, when vehicle is in high pressure topping up state, presses the 1QA button or press the JyA switch, just can jump over stops the topping up state, and directly is transferred to above-mentioned high pressure tapping state, and vehicle has correspondingly also just directly changed acceleration over to from slowing down.Also have, high pressure topping up in front or stop in the topping up state as long as vehicle runs into the upward slope road surface, and has certain gradient and length, and mercury switch (55) will automatically send electric signal, makes this device also change high pressure tapping state into.

In this state, the leakage flow of motor (14), (10), the check valve of flowing through (16), (9) are got back to oil outlet P1, P2 respectively, all are this flow directions in all tapping states of motor participation work.

(6). low pressure tapping state: when part (26) emitting along with fluid, when making its pressure be reduced to the rated value of single oil motor, yk1 rebounds automatically, sends electric signal, make the 3DT energising, " series connection tapping " when at this moment two gear motors are just by the high pressure tapping become " tapping in parallel ".High-voltage oil liquid is from O ₁And O ₂Flow into simultaneously.Low pressure fluid is again from P ₁And P ₂Flow out to fuel tank simultaneously.

When vehicle also is in low pressure topping up state, press 1QA or press JyA, just can skip middle all mode of operations, and directly be transferred to low pressure tapping state, the vehicle that has just reduced speed now changes over to again and give it the gun at once.

When the fluid in the part (26) was about to put, the 5J in the circuit was connected in the yk2 action of rebounding, and a break contact of its unique use disconnects, and system is all cut off the power supply, and changes attitude to be filled over to, and vehicle at the uniform velocity travels.Thereby, finish one by friction free speed-reducing, brake acceleration, the starting actuation cycle.

(7). high pressure attitude to be filled: stop topping up state vehicle when out of service when device is in, could start to walk once more after the time for a long time possibly.At this moment there is no need to allow the interior LXD of 1J, 3J, 4J and operator's compartment switch on for a long time.Its mode of all cutting off the power supply is had following three kinds: first kind is to open driver door, and the button MA that by the pressing of car door institute flicks, and total system is all cut off the power supply, and shuts driver door again and also can not switch on again, and this is well suited for the situation that the driver gets off; Second kind is to press the TA button, but driver's right crus of diaphragm just leaves brake pedal and Das Gaspedal before pressing, and must not go to jam on, otherwise backward or starting can appear in vehicle again; The third is to open the TKA switch, and all buttons and switch all outage are malfunctioning, close a switch before treating to start to walk again again.This state is compared with attitude to be filled, and unique difference is still to hold in the part (26) high-voltage oil liquid is arranged, so be called high pressure attitude to be filled.

(8). backward tapping state: when car brakeing is stopped and pressed the TA button, when making device be in high pressure to wait to fill attitude, as long as click the 1QA button again or remove to press the JZA button with right crus of diaphragm, will send electric signal, make the 1J energising, 2DT and DLM also are switched on, the P that flows through of the high-voltage oil liquid in the part in the oil circuit (26) ₂, O ₂, P ₁And O ₁Mouthful and enter fuel tank, driven gear motor and transmission shaft contrarotation.Equally, 3DT switches on again after pressure reduces, and motor becomes in parallel by series connection.

In this state, because the pointer of yk3 is to swing to the right, the 4J outage is not so the switching of JyA produces any influence for backward tapping state.But, when the backward speed of vehicle reaches P indicated on the certain value compression indicator ₃Value when approaching inflation pressure, the driver must press TA more again, and this state is finished.

(9). urgent topping up state: in the vehicle ' not pipe unit be in any mode of operation, driver when meeting emergency situation just can make device be transferred to this state rapidly as long as firmly jam on brake pedal.That is to say that urgent topping up state has significant exclusiveness characteristics.Its control signal is sent by the travel switch 3JA that is installed in below the brake pedal, pedal moves to end one, and it is just closed, makes 6J switch on, its three moving together contact and 3 break contacts play a role, 1J, 4J in the circuit, DLM, 2DT, when 3DT(yk1 is failure to actuate) energising.At this moment, not only part (10), (14) are switched on its brake action of performance, and friction lining in the former drg of vehicle or other motor component group are also brought into play brake action in succession.So this state can be described as the secondary braking topping up again, also can have successively three times, four times.If it only works in the last time when friction lining is arranged.The driver it should be noted that the power of stepping on brake pedal needn't be excessive too quickly, prevents that wheel from dragging cunning on the road surface.Because vehicle be drag when braking effect is than wheel rolling when sliding much lower.

Other motor component group is not drawn in Fig. 1, when linking as needs, and need only be with the O of each motor component group ₁, O ₂, P ₁And P ₂Four hydraulic fluid ports respectively connect a hydraulic control one-way valve that is off-state when flowing to fluid in motor, and then with Fig. 1 in the hydraulic fluid port of the same name of part (10), part (14) link, make to be the parallel connection relation between motor component group and the group.Out-of-run motor component group does not influence the element group of working.When a certain new element group of needs was worked, when clutch component was connected, the hydraulic control one-way valve in this group had fed high-voltage oil liquid owing to the control mouth and has all opened, thereby has further increased applied moment.Several stand-by motor component groups are arranged, just under brake pedal, have several travel switches.Do same installation under the Das Gaspedal, thereby in high pressure tapping state, further increase starting moment.When vehicle halted, the driver lifted brake pedal, and 3JA disconnects, the electromagnet outage of 6J, DLM and energising, and device is changed over to automatically by urgent topping up state and stops the topping up state.

(10). turn to the topping up state: the switch 5KA in the circuit is this state of realizing specially, it be installed in pole changer under, and switch direction unanimity abuts against together.Vehicle turn to travel before, the driver is when moving pole changer, 5KA is also moved together in the same way by inconjunction with.But which side no matter moves to, and 5KA can connect 6J, equally all makes 1J, 4J, DLM and electromagnet energising.At this moment the driver need only lift Das Gaspedal, not remove to jam on brake pedal, just can be implemented in the desirable travel situations that turns in the deceleration.Turn to after the end, when if vehicle just can quicken at once, driver's right crus of diaphragm only otherwise leave Das Gaspedal, make duplex button JyA be in on-state, so when moving back to pole changer and 5KA, device has just automatically changed over to and has discharged the high pressure tapping and the low pressure tapping state of hydraulic pressure energy, thereby vehicle is quickened.If turn to the back vehicle not need to quicken, before moving back to 5KA, driver's right crus of diaphragm leaves Das Gaspedal, correspondingly also just makes device stop the topping up state by turning to the topping up state to change over to.

(11). automatic tapping state: when vehicle at the uniform velocity travels, when device is in and waits to fill attitude, driver's right crus of diaphragm is to step down on the Das Gaspedal always.Because the existing of vibrational energy recovery device (below detailed description is arranged), it constantly charges into high-voltage oil liquid in energy storage (26), its pressure is constantly risen.When rising to certain numerical value, system will change fwd state (7) high pressure attitude to be filled automatically over to, and electric signal is sent in the yk1 action, makes Music centre loudspeaker LB, red eye HXD and relay 8J energising in the circuit.The resistance of resistance value will guarantee these three element parallel connections when element selected after after than DLM and 2DT parallel connection is much bigger, make 24 volts of DLM and 2DT(rated voltages) can never move in the moment of energising, but 8J guarantees action, and two moving together contact plays a role.Make the 7J energising again, three moving together contact and a break contact of 7J play a role, 1J in the circuit, 2J, 1DT, 8DT and DLM are all connected, system is when changing high pressure tapping state over to, also can automatically turn down the vehicle motor throttle, this action is that the change-over valve (30) among Fig. 2 is finished, this part is serially connected between fuel oil filter (33) and the diaphragm pump (32), because the energising of 8DT it just force fuel oil to flow through from flow regulating valve (31) on one side, reduced delivery quality, vehicle stabilization is travelled.

At this moment, Das Gaspedal is malfunctioning to the control of throttle, but owing to also be equipped with a cancel switch (58) that closes throttle automatically below Das Gaspedal, just pressurized disconnects when Das Gaspedal is stepped on nethermost end position.YQA is can be not open circuited in generally travelling, change high pressure attitude to be filled again over to after the parking of narrating for the front, as vehicle is started to walk once more, only depend on automatic tapping let-loose energy may be not enough to powered vehicle, promptly, the firm accelerator pedal of driver during starting, just find that HXD is shinny and hear the sound of LB, vehicle might not have the sign of starting, and at this moment the driver just can continue violent step on the accelerator and hang up forward gear, up to yQA is depressed, make 7J, 8J and 8DT outage, at this moment throttle just can strengthen, and the energy of driving engine is converged mutually with the energy that high pressure tapping state continues to emit, and common powered vehicle is advanced.When vehicle has possessed the starting speed driver as long as lift Das Gaspedal slightly, yk1 not repeller just can be transferred to automatic tapping state again.

For the vehicular traffic of engaging in transport outside the city, the tapping state will occur under steam continually automatically, and general every mistake repeated once in 2-5 minute.Therefore, this state is one of state that best embodies energy-conserving action.As long as suitably adjust flow regulating valve (31) and yk1, make in this state because of turning down also to show a small surplus after energy that energy that throttle saves just in time exported by automatic tapping remedies or remedies.In order to keep the stationarity of the speed of a motor vehicle, allow energy discharge more slowly, 3DT is in off-position always.Because therefore the JZA button, is easily by automatic tapping state exchange to low pressure topping up and urgent topping up state connecting 1J simultaneously also with the 2J disconnection.

(12). backward topping up state: when the vehicle backward, the duplex button DA that is installed in Das Gaspedal and brake pedal intersection the place ahead or other position is jammed on the right crus of diaphragm point, the right crus of diaphragm heel moves on on the brake pedal, just can make 7J in the circuit, 1J, 2J, part (11) and 1DT energising, the P of oil motor (10) and (14) ₂Mouth flows into low pressure fluid, and O1 mouth output high-voltage oil liquid to energy storage (26) topping up, thereby produces the brake snub effect to the vehicle of backward; When the right crus of diaphragm tiptoe lifted, DA button (61) was opened, and this state also finishes thereupon.

(13). shift to an earlier date the tapping state: when normal vehicle operation, run into empty a bit of uphill road as the place ahead, mercury switch has little time to connect will climb to sloping the top.Energy storage this moment (26) contain fluid but relay yk1 action as yet, the driver can remove to jam on duplex button DA with the right crus of diaphragm tiptoe, the right crus of diaphragm heel is still stayed on the Das Gaspedal, and the element of switching in the circuit is identical with Last status, but fluid flows to and the motor switched in opposite.This moment vehicle not open the throttle wide just increased a kinetic moment of advancing, impel vehicle to quicken to rush across sloping road, lift the right crus of diaphragm point, this state finishes immediately.

(14). dissengaged positions: when the braking energy-saving system broke down for a long time because of using, the driver only need open the TKA switch, part (28) commutation valve plate was drawn be midway location, and whole braking reclaiming scrap promptly quits work.The high-voltage oil liquid of vibrational energy recovery device output also flows back to fuel tank from the pipeline that connects (28).Vehicle travels by original maneuverability pattern, can not take place to damage the phenomenon that vehicle is cast anchor because of the braking reclaiming scrap.As adopt backguy, during drawing article (28), chaufeur need not leave the seat; Also need not stop and just can finish the conversion of dissengaged positions.

As seen, the braking reclaiming scrap constitutes simple, multiple functional.Considering that this device can install and use on different types of vehicle, is to be provided with manually and foot-operated two kinds of modes basically in the control circuit of Fig. 4.For example: the deceleration of vehicle and both quicken can plate under switch (47) manually finish with this button of 1QA, also can step on and finish with the button pin on the pedal surface.For concrete a kind of vehicular traffic, there is no need these two kinds of modes are all installed, select a kind of getting final product for use.Be advisable to adopt to ride such as vehicle to automobile one class.Because this mode meets driver's operating habit fully, right crus of diaphragm is as long as press brake pedal gently, and vehicle just slows down, and when going to press Das Gaspedal again, vehicle just quickens.This has just reduced driver's labour intensity (the brake pedal legpower can reach 70 kilograms on the automobile).

The vibrational energy regenerative apparatus mainly by the element among Fig. 1 (1)-(7) totally seven elements form, wherein check valve (6) is connected with energy storage (26), it only allows this system to charge into high-voltage oil liquid in (26), and in the flow of liquid return device that does not allow part in (26).Check valve (7) then provides low pressure fluid to device, and it communicates with fuel tank (19).The rod oil cylinder (1) that singly goes out in the device is used for replacing bumper, and the available bumper transformation of the way forms, but should guarantee that its installation dimension is constant after the transformation of the way, narrow hole on the former shock absorber piston must all be shut, and an oil through is respectively opened at the simple wall two ends after intensity improves, its installation site and former bumper are identical, can be strengthened support.In general two vibrational energy regenerative apparatuss all are installed on each vehicle bridge, and each is independent mutually each other, be independent of each other, and four such devices just are installed in Fig. 1.The mode of operation of this system has following five kinds.

(15). normal liquid-filled state: when vehicle travels on straight highway, electromagnet 4DT, 5DT, 6DT, 7DT in four devices are in off-position, because vibration of vehicle, when the distance between vehicle body and the vehicle bridge shortens, the motion of piston is a compression stroke in the part (1), at this moment, does not have low pressure fluid to replenish in system, the connection mode of system is differential connection, and the fluid volume of being discharged is the volume of piston rod part.And in the opposite stretching travel of piston motion direction, check valve (7) is opened, and low pressure fluid is provided for the rodless cavity of part (1) by fuel tank (19), and the high-voltage oil liquid that rod chamber flows out is through all output of part (6).As seen, the high-voltage oil liquid in above-mentioned two strokes is outwards exported, and all is to flow through part (34) flow regulating valve and charge in the energy storage (26), and sequence valve (35) is cutting out in this state all the time.At this moment, part (2) no power, part (3) is inoperative.

Below its characteristic is analyzed discussion:

Part (26) is as long as there is fluid to charge into, and its pressure just should raise, but because the capacity of this part is enough big, and the topping up flow is very little, so the value that the short time internal pressure increases is very small with respect to the gross pressure value.For a stroke in the vibration, we might as well ignore this pressure excess, think that the pressure in the part (26) is a constant P ₀, and ignore friction drag in the piston motion, then singly go out the total damping power F of rod oil cylinder _AlwaysCan be expressed as:

F _Always=P ₀S+ △ PS=F+ △ F (1)

Effective active area when S represents piston motion in the formula, its value equals piston rod sectional area S1 in the compression stroke, its value is rod chamber active area S2 in the stretching travel, part (1) all guarantees to make S2＞S1 on structure, so, the normal liquid-filled state can satisfy the characteristic requirement that compression damping power is little, the stretching dumping force is big of former bumper just.

Because constant resistance F=P ₀The size of S and vibration velocity has no relation, the value of vibration damping resistance △ F=△ PS, and fully owing to vibration just causes, so, constitute F _AlwaysTwo component from being distinct in nature.We might as well regard by two unit construction and form that one of them is the constant resistance element to conversion cylinder (1) as, and another is a damper element.We become elongated aperture to part (1) to the pipeline of part (26) with part (34) equivalence, and according to the empirical equation on the relevant handbook, the dumping force △ F that belongs to damper element shows with regard to the formula below available.

$\mathrm{△\; F\; =\; △P\; ·S\; =\; 7.2}\frac{\mathrm{<figure-callout\; id="2"\; label="V\; d"\; filenames="86100291\_DRIMG1.png"\; state="\{\{state\}\}">V</figure-callout>}}{d^{}}\mathrm{L\; S\; =\; 7.2}\frac{\frac{\mathrm{d\; Z}}{\mathrm{d\; t}}·\frac{\mathrm{4S}}{{\mathrm{\pi \; d}}^2}}{{\mathrm{<figure-callout\; id="2"\; label="d"\; filenames="86100291\_DRIMG1.png"\; state="\{\{state\}\}">d</figure-callout>}}^2}\mathrm{L\; S}$

=(28.8S ²L)/(π d ²) (dZ)/(dt)=K (dZ)/(dt) (kilogram) (2)

In the formula: the loss of pressure (kilograms per centimeter in the elongated aperture of △ P-equivalence ²);

S-piston effective active area (centimetre ²);

The speed (meter per second) of fluid in the elongated aperture of V-;

The internal diameter of the elongated aperture of d-(millimeter);

The length of the elongated aperture of L-(rice);

(dZ)/(dt)-Vehicular vibration instantaneous state of velocity (meter per second);

K-damper element drag coefficient, it is a constant.

As seen, as long as we are chosen to be the flow regulating valve of elongated pinhole type with part (34), it is identical with former bumper that the effect of damper element will become, and its dumping force also is proportional with vibration velocity, and expression formula is the same.

At this moment, as mass distribution coefficient ε=1 of picking up the car, the free vibration differential equation of the suspended mass M of single vibration system can be written as:

M (d ²Z)/(dt ²) +K (dZ)/(dt) +CZ+F=0 (3）

If make 2h=(K)/(M) then following formula can be rewritten as:

(d ²Z)/(dt ²) +2h (dZ)/(dt) +W ²Z＝- (F)/(M) （4）

In the formula: $\mathrm{W\; =}\sqrt{\frac{C}{M}}$

-vehicle free vibration offset frequency;

The C-suspension rate.

The pairing homogeneous equation of equation (4) is exactly the differential equation when former bumper is installed:

(d ²Z)/(dt ²) +2h (dZ)/(dt) +W ²Z＝0 （5）

General h＜w, in the case, equation (5) separate for:

${\mathrm{Z\; =\; A\; ·e}}^{\mathrm{-\; h\; t}}\mathrm{·s\; i\; n\; (}\sqrt{w{}^2\mathrm{-\; <figure-callout\; id="2"\; label="h"\; filenames="86100291\_DRIMG1.png"\; state="\{\{state\}\}">h</figure-callout>}{}^2}\mathrm{·t\; +\; \phi )}$ （6）

If (4) form of formula particular solution is: Z ^*=b then has: Z ^*'=Z ^*"=0 is updated in the equation (4):

$Z^{＊}\mathrm{=\; -}\frac{\mathrm{<figure-callout\; id="2"\; label="F\; MW"\; filenames="86100291\_DRIMG1.png"\; state="\{\{state\}\}">F</figure-callout>}}{{\mathrm{M\; W}}^{}}\mathrm{=\; -}\frac{F}{M\frac{C}{M}}\mathrm{=\; -}\frac{F}{C}$

So, equation (4) separate for:

${\mathrm{Z\; =\; A\; ·e}}^{\mathrm{-\; h\; t}}\mathrm{·s\; i\; n\; (}\sqrt{w{}^2\mathrm{-\; <figure-callout\; id="2"\; label="h"\; filenames="86100291\_DRIMG1.png"\; state="\{\{state\}\}">h</figure-callout>}{}^2}\mathrm{·t\; +\; \phi \; )\; -}\frac{F}{C}$ (7)

Be located in the compression stroke Z on the occasion of, rigidity C is identical with constant-resistance power F direction, opposite with direction of vibration with the suspension elastic force of the product formation of Z, so when Z be on the occasion of the time, (F)/(C) also be on the occasion of; And Z is a negative value in stretching travel, and the direction that hangs elastic force is opposite with constant-resistance power F direction, and then (F)/(CZ) also becomes negative value.Leaving for comparison (7) formula by above-mentioned conclusion just can find with (6) formula: after loading onto the constant resistance element, though its damped vibration frequency does not change, but make the amplitude of vibration further decay again, can trend towards quickly stablizing, this attenuation also strengthens with the rising of part (26) internal pressure.

On the other hand, also can further alleviate actual pressure that bears of suspension and impulsive force after the raising F value, thereby make the load-carrying capacity of vehicle be improved.The life-span of elastic element also can therefore and greatly prolong.Certainly, the raising of F must be limited in certain scope, consider the permission of element (1) two ends Joint strenght, and part (26) force value to brake accumulator standby give stay, and guarantee to discharge hydraulic pressure can the time speed of a motor vehicle as far as possible steadily.The automatic tapping state of fwd is exactly to aim at the restriction peak of F and design-calculated.

(16). force the topping up state: urgent topping up of state (9) and state (10) turn in the topping up in front, because the effect of force of inertia, vehicle body can be forward, tilt suddenly to the outside that turns to, these two kinds of inclinations all can bring and significantly compress and uphold to singly going out rod oil cylinder (1), and give very big impulsive force of suspension of vehicle.For increase hydraulic pressure can output, make this impact energy by part (26) absorb more more.At this moment, vibrational energy regenerative apparatus oil circuit directional control valve comprises a two-position three way solenoid electric valve (2) and five check valves (3), (4), (5), (6), (7).In above-mentioned (9), (10) two states, when finishing former action, 4DT, 5DT, 6DT, 7DT are all switched on, make part (1) in compression stroke, the fluid that rodless cavity is discharged is through part (5), part (6) and all outwards output no longer be differential bonded assembly form, and low pressure fluid is to charge into to rod chamber through part (3) at this moment, in stretching travel then be through part (4), part (6) to part (26) topping up, low pressure fluid is still through part (7) and flows into.

Because this state is to work simultaneously with the braking reclaiming scrap,, vehicle is slowed down on piece ground to the greatest extent so the setting of pressure topping up also can improve the lock torque of part (10), part (14) effectively.Can also improve the cornering properties of vehicle in addition, the stable turning radius improves load-carrying capacity.

When the vibrational energy regenerative apparatus is used on railroad vehicle, can not occur significantly vibrating,, not force topping up so only have the normal liquid-filled state.Correspondingly just can replace the element among Fig. 1 (2) with straight-through oil pipe, element (3), (4) and pipeline direct coupled with it also all save, and only remaining three check valves (5), (6), (7) and part (1) are connected into the differential connecting mode in the laststate.

(17). convex-concave topping up state: when running into the rough and uneven in surface road surface that is bordering on corrugated road in the vehicle ', the speed of a motor vehicle is very slow in the time of both yet can make the vehicle body severe jolt, puncture (crusherbull zone piece) for fear of suspension system, improve the flow of output fluid, the driver can be temporarily moves the 5KA switch in the circuit to the right together with the 4KA switch that is installed in below it, make 1J, 3J, 4J, 6J, 4D, T, 5DT, 6DT, 7DT energising in the circuit, vibrational energy recovery device works independently by the mode in the state (16), and the braking reclaiming scrap is not worked.This state continuance was connected HXD and LB branch line because of the action of yk1 after a period of time, when the driver finds red signal or hears loudspeaker stereo, just should together move back to midway location to 4KA and 5KA.At this moment, as long as driver's right crus of diaphragm still steps down on the Das Gaspedal, device will change high pressure tapping state over to automatically at once.

(18). off-load topping up state: also be parallel with the sequence valve (35) that can realize the off-load topping up on one side at flow regulating valve (34).When the vehicle body amplitude reaches certain value (for example: 3 centimetres), no matter which kind of mode of operation vibrational energy recovery device is in, sequence valve (35) all will be opened automatically, thereby reduces the value of fluid along stroke pressure loss △ P, reduce damping resistance △ F, the suffered impulsive force of vehicle body is diminished.

We might as well suppose that a kind of △ P, △ F are reduced to zero limiting case, at that time the only surplus next constant resistance F=P of element (1) ₀S, piston move to any one position, and it all will be subjected to this unmodified Resistance Value.When part (1) when being in compression stroke, power F only offsets a part constant in the vehicle body gravity, when at this moment if wheel has increased an impulsive force that makes progress again suddenly newly, at this moment cannot take out any point power among the power F and offset this impulsive force, go, that is to say and all impulsive force has been absorbed by the elastic element in hanging, constant force F can not pass to extra impulsive force on the vehicle body, therefore, reduce unique effective method of the suffered impulsive force of vehicle body, reduce the value of △ P and △ F exactly.

(19). load carrying ability is measured state.In the delivery conduit after each vibrational energy regenerative apparatus converges, also be in series with a 3-position-3-way change-over valve (28), in minute oil circuit, also have and to measure each and singly go out the rod oil cylinder internal pressure, demonstrate each wheel gravity distribution condition; Thereby can measure the pressure gravity table of the actual pay load of vehicle.Before lade, the driver is pulled to position, a left side with 3-position-3-way hand change over valve (28) among Fig. 1 by the shown position plate earlier, but in the process that plate draws, change-over valve (28) must make four singly to go out the whole off-loads of rod oil cylinder through midway location, that is to say that oil pressure has dropped to and approached null value in the cylinder when pulling to position, a left side.This moment, the weight when empty of vehicle was all born by suspension gear, again on car during lade, because each oil outlet that singly goes out rod oil cylinder is all shut, and become the supporting member of rigidity, therefore, the weight of the thing of freighting will all be born by the pressure of four oil cylinders by rising cylinder inner fluid, our pressure meter switch in need only rotation combination element (29), measure the size of P6, P7, P8 and four force value of P9 and gravity value respectively, just can learn the weight of lade and the situation that each wheel gravity distributes thereof.

Certainly, the weight of the thing of freighting also must be in certain number range, by the intensity that singly goes out rod oil cylinder is allowed.So-called pressure gravity table, corresponding gravity numerical value gets final product on just adding in the outside of the pressure value on the compression indicator again, and two numerical value only differ from a constant of proportionality, when the differential connecting mode when singly going out rod oil cylinder by the diagram normal liquid-filled connected, this constant of proportionality was exactly the sectional area of piston rod.If a button and a little intermediate relay are set again, only the 4DT in the circuit, 5DT, 6DT, 7DT and 1J are connected, so, press that constant of proportionality has been exactly the active area of rodless cavity piston behind the button, change-over valve this moment (28) also can change electromagnetic control into or adopt standard component to combine.
