*8006455-3 2 » M varvtalet hos hjulen på varje hjulaxel och jämför detta med varvtalet hos en frirullande hjulaxel eller ett frirullande hjul på fordonet samt_att man vid konstaterade skillnader mellan dessa varvtal, vilka skillnader överstiger ett förutbestämt gränsvärde och är av längre gvaraktighet än en förutbestämd minsta tid, utlöser en impuls till _reglersystemet för minskning av hydraultrycket P i kraftöverföringen under en förutbestämd tidsperiod. * 8006455-3 2 »M the speed of the wheels on each wheel axle and compare this with the speed of a free-rolling wheel axle or a free-rolling wheel on the vehicle and_that at observed differences between these speeds, which differences exceed a predetermined limit value and are of longer durability than a predetermined minimum time, triggers an impulse to the control system to reduce the hydraulic pressure P in the power transmission for a predetermined period of time.
Tack vare uppfinningen kan säkerheten vid inbromsning av for- don med drivsystem med hydrostatisk kraftöverföring ökas högst betyd- ligt och¿samtidigt kan accelerations- och framdrivningskraften steg- ras och göras jämnare. "Genom den bättre inbromsningsförmågan förbil- ligas hjulunderhållet särskilt när det gäller rälsgående fordon och som helhet kan detta förfarande tillämpas med mycket enkla_och därmed 'billiga åtgärder vid reglersystem för hydrostatiska kraftöverföring- ar.Thanks to the invention, the safety when braking vehicles with drive systems with hydrostatic power transmission can be increased very significantly and at the same time the acceleration and propulsion force can be increased and made more even. "Due to the better braking ability, wheel maintenance is made cheaper, especially in the case of rail vehicles, and as a whole this procedure can be applied with very simple_and thus' cheap measures in control systems for hydrostatic power transmissions.
Uppfinningen beskrives närmare nedan under hänvisning till bi- fogade ritning, på vilken fig. 1 visar en schematisk perspektivvy av ett hydrostatiskt drivet tåg, fig. 2 visar ett blockschema över reg- leringsfunktioner vid ett hydrostatiskt drivsystem som utnyttjas vid det nyssnämnda tåget och figÄ Ba och b visar slutligen ett tidsfunk. tionsschema för de erforderliga regleringsparametrarna för den hydro- statiska kraftöverföringen enligt uppfinningen. , Såsom framgår av ritningen skall förfarandet enligt uppfinning- en beskrivas i första hand tillämpat på ett hydrostatiskt drivsystem för ett tåg. Drivkraftkällan utgöres härvid av en förbränníngsmotor 1, som på lämpligt sätt är drivande förbunden med ett par hydraul- pumpar 2. Dessa pumpar 2 driver var sin hydraulmotor 3, vilka vial kuggväxlar 4 driver var sin hjulaxel 5. Vid det visade utförings- exemplet utgöres hydraulpumparna 2 av kända axialkolvpumpar med ett deplacement qlp, som är varierbart genom omställning av utsvängnings- eller okvínkeln, medan hydraulmotorerna 3 har fast deplacement q>m (även om variabelt motordeplacement är fullt möjligt).The invention is described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows a schematic perspective view of a hydrostatically driven train, Fig. 2 shows a block diagram of control functions in a hydrostatic drive system used in the above-mentioned train and Fig. Ba and b finally shows a time function. diagram for the required control parameters for the hydrostatic power transmission according to the invention. As can be seen from the drawing, the method according to the invention will be described primarily applied to a hydrostatic drive system for a train. The driving power source is in this case an internal combustion engine 1, which is suitably connected to a pair of hydraulic pumps 2. These pumps 2 each drive their own hydraulic motor 3, which vial gears 4 each drive their own wheel axle 5. In the embodiment shown, the hydraulic pumps are 2 of known axial piston pumps with a displacement qlp, which is variable by adjusting the swing-out or angular angle, while the hydraulic motors 3 have a fixed displacement q> m (although variable motor displacement is entirely possible).
För reglering av det av hydraulmotorerna alstrade drivmomen- tet finns också ett reglersystem, till största delen inrymt i en reglerenhet 6. Detta system innefattar olika lämpliga och kända men icke närmare visade givarorgan för erforderliga regleringsparametrar för den hydrostatiska kraftöverföringen, såsom drivmotorvarvtalet N, pumpdeplacementet Np, motordeplacementet dnloch eventuellt också hydraultrycket P i kraftöverföringen. Dessutom finns en icke heller visad varvtalsgivare för en icke driven eller frirullande hjulaxel 7 i tåget. 8006455-*5 3 _,_ På basis av de av givarorganen fastställda momentanvärdena för de nämnda regleringsparametrarna beräknas nu enligt uppfinningen kontinuerligt i reglerenheten 6 varvtalet hos hjulen på varje hjul- axel 5 och jämförs med varvtalet hos det frirullande hjulet eller hjulaxeln 7. Om därvid en skillnad mellan dessa varvtal konstateras i reglerenheten 6, vilken skillnad alltså beror på att någon eller några av de drivna hjulaxlarna antingen roterar fortare än den fri- rullande hjulaxeln 7, dvs. slirar under acceleration, eller långsam- mare än denna, dvs. glider i låst tillstånd mot underlaget under bromsning, och denna skillnad visar sig överstiga ett förutbestämt gränsvärde och dessutom varar längre än en förutbestämd minsta tid, så utlöses i reglerenheten 6 en impuls för sänkning av hydraultrycket P så mycket att slirningen eller glidningen upphör, dvs. likhet mel- lan varvtalen åstadkommes. Med andra ord uttryckt kan man säga att man återställer flödesbalansen i det hydrostatiska drivsystemet.For controlling the drive torque generated by the hydraulic motors, there is also a control system, mostly housed in a control unit 6. This system comprises various suitable and known but not shown sensors for required control parameters for the hydrostatic power transmission, such as the drive motor speed N, the pump displacement Np , the engine displacement dnloch possibly also the hydraulic pressure P in the power transmission. In addition, there is also a speed sensor (not shown) for a non-driven or free-rolling wheel axle 7 in the train. 8006455- * 5 3 _, _ On the basis of the instantaneous values determined by the sensor means for the said control parameters, the speed of the wheels on each wheel axle 5 is now calculated continuously in the control unit 6 and compared with the speed of the free-rolling wheel or wheel axle 7. If a difference between these speeds is found in the control unit 6, which difference is thus due to one or some of the driven wheel axles either rotating faster than the free-rolling wheel axle 7, ie. slips during acceleration, or slower than this, ie. slides in the locked state against the ground during braking, and this difference turns out to exceed a predetermined limit value and also lasts longer than a predetermined minimum time, so in the control unit 6 an impulse for lowering the hydraulic pressure P is triggered so much that slipping or sliding ceases, ie. similarity between speeds is achieved. In other words, you can say that you restore the flow balance in the hydrostatic drive system.
Värdet Pi på trycket i det hydrostatiska drivsystemet, som rådde då denna varvtalsskillnad uppmättas och trycksänkningen påbörjades lagras i en minnesenhet i reglerenheten 6 och efter en förutbestämd tid avger reglerenheten 6 en ny impuls för ökning av hydraultrycket P, dock till en nivå IE, som ligger klart under ingångsvärdet Pi.The value Pi of the pressure in the hydrostatic drive system, which prevailed when this speed difference was measured and the pressure drop started, is stored in a memory unit in the control unit 6 and after a predetermined time the control unit 6 emits a new impulse to increase the hydraulic pressure P, however to a level IE, which is well below the input value Pi.
Härigenom tillförsäkras att slirnings- eller glidningstillståndet icke genast återkommer på nytt. Efter ännu en förutbestämd tid av- ger reglerenheten sedan till slut en ny impuls för återställande av hydraultrycket till värdet Pi. 7 Som praktiska exempel på värdena vid regleringsförfarandet enligt föreliggande uppfinning hänvisas till fig. 3 på ritningen och de däri visade diagrammen över de viktigaste reglerparametrarna, varav framgår att man med 6ü millisekunders intervall utför jämförel- se mellan verkligt och beräknat hjulvarvtal och vid konstaterade skillnader över ett förutbestämt minimivärde minskar hydraultrycket . P i kraftöverföringen så att slirningen eller glidningen mellan drivan- de hjulaxlar och underlag upphör. Efter en förutbestämd tidsperiod ökar reglersystcmet sedan åter hydraultrycket men endast till en ni- vå Pr, som utgör ca 80% av Pi. hetta reducerade tryck upprätthålls under en förutbestämd tidsperiod av i detta fall 10 sekunder, varef- ter en ny impuls från reglersystemet bringar hydraultrycket till att återta värdet Pi.This ensures that the slip or slip condition does not return immediately. After another predetermined time, the control unit then finally emits a new impulse for resetting the hydraulic pressure to the value Pi. As a practical example of the values in the control method according to the present invention, reference is made to Fig. 3 of the drawing and the diagrams shown therein of the most important control parameters, from which it is shown that at 6ü millisecond intervals comparisons are made between actual and calculated wheel speeds. a predetermined minimum value reduces the hydraulic pressure. P in the power transmission so that the slippage or slippage between the driving wheel axles and the ground ceases. After a predetermined period of time, the control system then increases the hydraulic pressure again, but only to a level Pr, which constitutes about 80% of Pi. heat reduced pressures are maintained for a predetermined time period of in this case 10 seconds, after which a new impulse from the control system causes the hydraulic pressure to regain the value Pi.
Fördelarna med reglerförfarandet enligt föreliggande uppfin- ning är många. För det första räcker ett enda mätvärde, nämligen varvtalet hos ett enda frirullande hjul eller en enda frirullandeThe advantages of the control procedure according to the present invention are many. First, a single measured value is sufficient, namely the speed of a single free-rolling wheel or a single free-rolling wheel.
