Abstract
Description
Prezenta invenție se refera la o cutie de viteze automata care este plasata intre motor si transmisia finala .fiind destinata oricărui tip de autovechicul.The present invention relates to an automatic gearbox which is placed between the engine and the final transmission. It is intended for any type of motor vehicle.
In scopul transmiterii puterii de la motor la rotile motoare sunt cunoscute cutii de viteza automate cu mai multe trepte, cu ambreiaj cu discuri pentru fiecare pinion de acțiune.In order to transmit the power from the motor to the motor wheels are known automatic gearboxes with several steps, with clutch with discs for each sprocket of action.
Dezavantajul acestor cutii consta in faptul ca discurile din ambreiaj sunt acționate continuu de către o pompa de ulei actionata de motor, fapt ce duce la scăderea puterii acestuia.The disadvantage of these boxes is that the clutch discs are driven continuously by an engine-driven oil pump, which results in its power loss.
Un alt dezavantaj reprezintă faptul ca aceste cutii de viteza automate au masa si volumul mari si sunt foarte complexe.Another disadvantage is that these automatic gearboxes have large mass and volume and are very complex.
Problema tehnica pe care o rezolva invenția de fata este realizarea unei cutii de viteza automata, care sa permită micșorarea puterii consumate de motor pentru acționarea pompei de ulei, prin acționarea temporara a acesteia doar la schimbarea treptelor de viteza.The technical problem that the present invention solves is the creation of an automatic gearbox, which allows to reduce the power consumed by the engine to drive the oil pump, by temporarily actuating the oil only when changing gears.
Cutia de viteze automata, conform invenției, înlătură dezavantajele de mai sus prin aceea ca, este constituita dintr-un arbore primar pe care este montata o camera de presiune si un ambreiaj hidraulic, racordate hidraulic si alimentate cu ulei sub presiune de la un distribuitor hidraulic, arborele primar fiind cuplat la căpătui opus motorului la o pompa de ulei si dintr-un arbore secundar pe care sunt montate alte camera de presiune racordate la alte ambreiaje hidraulice. Intre pompa de ulei, distribuitorul hidraulic si rezervorul de ulei fiind prevăzut un regulator de presiune, iar distribuitorul hidraulic fiind cuplat hidraulic si cu un amortizor hidraulic. Pompa de ulei este prevăzută cu o camera superioara care înconjoară pe toata suprafața de lucru pistonul, pentru a realiza o buna ungere a acestuia. Distribuitorul hidraulic este prevăzut cu un canal prin care este alimentat cu ulei sub presiune si cu niște pistoane prin care, in urma deschiderii uneia dintre electrovalvele pot fi deplasate pentru a deschide sau închide niște canale prin care uleiul este debitat către unul dintre ambreiajele in vederea cuplării ^-2010-00924-Ο 1 -10- 2010The automatic gearbox, according to the invention, removes the above disadvantages by the fact that, it consists of a primary shaft on which is mounted a pressure chamber and a hydraulic clutch, hydraulically connected and supplied with pressure oil from a hydraulic distributor , the primary shaft being coupled to the head opposite the engine to an oil pump and from a secondary shaft on which are mounted other pressure chamber connected to other hydraulic clutches. Between the oil pump, the hydraulic distributor and the oil reservoir are provided with a pressure regulator, and the hydraulic distributor is hydraulically coupled and with a hydraulic damper. The oil pump is provided with an upper chamber that surrounds the entire work surface of the piston, in order to achieve a good lubrication thereof. The hydraulic distributor is provided with a channel through which it is supplied with pressurized oil and with pistons through which, after opening one of the solenoid valves, they can be moved to open or close some channels through which the oil is charged to one of the clutches for the purpose of coupling. ^ -2010-00924-Ο 1 -10- 2010
acestora asfel incat la un moment dat sa fie alimentat cu ulei doar un singur ambreiaj si, de asemenea, de a permite scăderea persiunii dintr-un ambreiaj prin deschiderea unei cai formata de niște canale si o gaura filetata spre rezervorul de ulei. Ambreiajul hidraulic este prevăzut cu un tambur solidar cu arborele primar si cu o coroana de cuplare care se sprijină pe niște rulmenți si care se afla in angrenare, printr-o coroana dintata, cu roata dintata de pe arborele secundar, tamburul fiind prevăzut cu niște camera radiale in care se pot deplasa liber niște pistoane si niște bile care se pot impana, la creșterea presiunii uleiului intr-un canal circular prin pătrunderea lor in niște adâncituri ale unui canal astfel incat sa se realizeze un contact rigid intre tamburul si coroana de cuplare. Regulatorul de presiune este alcătuit dintr-un element tubular si dintr-un element secundar in interiorul si in lungul axei acestora deplasandu-si o tija culisanta menținută in poziția de lucru de la un arc elicoidal ce presează asupra unui disc opritor pentru a permite trecerea uleiului ce vine de la rezervorul de ulei printr-o gaura filetata spre o alta gaura filetata pentru a ajunge in final la pompa de ulei, la creșterea presiunii in circuit producandu-se o apasare printr-o gaura filetata asupra tijei, uleiul intrând prin aceasta si ieșind printr-o alta gaura filetata pentru a ajunge la rezorvorul de ulei, iar o gaura filetata servind prin presiunea de lucru exercitata pe căpătui tijei la pastrarea poziție de lucru.so that at one point only one clutch can be supplied with oil and also to allow the clutch to be lowered by opening a channel formed by channels and a threaded hole towards the oil reservoir. The hydraulic clutch is provided with a drum integral with the primary shaft and with a coupling crown which rests on some bearings and which is engaged, by means of a toothed crown, with the gear wheel on the secondary shaft, the drum being provided with some chamber radials in which some pistons and balls can be freely moved, to increase the oil pressure in a circular channel by penetrating them into some grooves of a channel so that a rigid contact between the drum and the coupling crown is made. The pressure regulator is composed of a tubular element and a secondary element inside and along their axis by moving a sliding rod maintained in the working position from a helical spring that presses on a stop disk to allow the oil to pass through. what comes from the oil reservoir through a threaded hole to another threaded hole to finally reach the oil pump, increasing the pressure in the circuit producing a pressure through a threaded hole on the rod, the oil entering through it and exiting through another threaded hole to reach the oil reservoir, and a threaded hole serving through the working pressure exerted on the head of the rod to maintain the working position.

Cutia de viteze automata, conform invenției, este alcatuita dintr-un arbore primar 1, sprijinit pe niște lagare 2, 3, 4 si 5, arbore 1 care este cuplat la un capat cu un motor 6 , iar la celalalt, prin intermediul unei manivelei 7, la o pompa de ulei A.The automatic gearbox, according to the invention, consists of a primary shaft 1, supported on bearings 2, 3, 4 and 5, shaft 1 which is coupled at one end with a motor 6, and at the other, by means of a crank. 7, at an oil pump A.
Pe arborele primar 1 este montata o camera de presiune 8 care permite transmiterea uleiului de la un distribuitor hidraulic B intr-un canal axial a al acestuia.On the primary shaft 1 is mounted a pressure chamber 8 which allows the transmission of the oil from a hydraulic distributor B in an axial channel thereof.
In apropierea camerei de presiune 8 este plasat un ambreiaj hidraulic C solidar, printr-un tambur 9, la arborele primar 1 .Pe exteriorul tamburului 9 se sprijină, prin niște rulmenți radiali 10 si 11 o coroana de cuplare 12 dotata la exterior cu o coroana dintata b a uneia dintre treptele cutiei, conform invenției.Near the pressure chamber 8 is placed a hydraulic clutch C integrally, through a drum 9, at the primary shaft 1. On the outside of the drum 9 is supported, by means of radial bearings 10 and 11, a coupling crown 12 provided on the outside with a crown tooth of one of the steps of the box according to the invention.
Pe arborele primar 1, in afara ambreiajului hidraulic C, in funcție de numărul de trepte necesar, mai pot fi montate si alte roti dintate, ca de exemplu, rotile dintate 13 si 14 care sunt solidare cu arborele primar 1.On the primary shaft 1, apart from the hydraulic clutch C, depending on the number of steps required, other sprockets, such as the sprockets 13 and 14, which are integral with the primary shaft 1, may also be fitted.
Amintita pompa de ulei A este actionata cu ajutorul manivelei 7 si a unei biele 15 care pune in mișcare un piston 16. O camera superioara c, care are in permanenta ulei si care comunica la partea superioara cu o supapa de admisie 17 si o supapa de evacuare 18. Admisia uleiului in camera superioara c prin supapa 17 se face printr-un furtun 19 racordat la un regulator de presiune D.The aforementioned oil pump A is actuated by means of crank 7 and a connecting rod 15 which sets up a piston 16. An upper chamber c, which has permanently the oil and which communicates at the top with an inlet valve 17 and an inlet valve 17 exhaust 18. The oil inlet in the upper chamber c through the valve 17 is made through a hose 19 connected to a pressure regulator D.
Cutia de viteze, conform invenției, este prevăzută si cu un arbore secundar 20 sprijinit pe niște lagare 21 si 22, pe care este solidara o roata dintata 23 aflata in (\-2 010 - Ο Ο 9 2 4 - Ο 1 -ΙΟ- 2010 4 angrenare cu coroana dintata b a coroanei de cuplare 12. Pe același arbore secundar 20 mai sunt montate niște camere de presiune 24 si 25 prin care uleiul sub presiune este adus in niște ambreiaje hidraulice E si F, similare constructive cu ambreiajul hidraulic C de pe arborele primar 1.The gearbox, according to the invention, is also provided with a secondary shaft 20 supported on bearings 21 and 22, on which a gear 23 is located in (\ -2 010 - Ο Ο 9 2 4 - Ο 1 -ΙΟ- 2010 4 gear with gear tooth and coupling ring 12. On the same secondary shaft 20 there are mounted pressure chambers 24 and 25 through which the oil under pressure is brought into hydraulic clutches E and F, similar to the hydraulic clutch C on the primary tree 1.
Deosebirea consta in faptul ca pe coroana de cuplare 12 in cazul ambreiajului E ca si in cazul ambreiajului F acestea sunt dotate cu niște coroane dintate dsi e coresupunzatoare cuplării lor cu rotile dintate 13 si 14.The difference is that on the coupling ring 12 in the case of the clutch E as in the case of the clutch F these are equipped with some gear crowns, but it is appropriate for their coupling with the gear wheels 13 and 14.
Camera de presiune 8 permite trecerea uleiului sub presiune, adus printr-un furtun 26 de la distribuitorul B, printr-o canalizatie f al arborelui primar 1 spre ambreiajul hidraulic C unde pătrunde intr-un canal circular g, iar de aici in niște camere radiale h. In fiecare dintre acestea sunt poziționate liber cate un piston 27 si o bila 28, acest ultim element aflandu-se in contact cu un canal i, practicat in coroana de cuplare 12 si a cărui perimetru are niște adâncituri j ,cu o raza mai mare decât a celorlalte porțiuni ale canalului i. Numărul de adâncituri /este egal cu cel al camerelor radiale h.The pressure chamber 8 allows the passage of the oil under pressure, brought through a hose 26 from the distributor B, through a pipe f of the primary shaft 1 to the hydraulic clutch C where it enters a circular channel g, and from here into some radial chambers. h. In each of these, a piston 27 and a ball 28 are freely positioned, the latter element being in contact with a channel i, practiced in the coupling crown 12 and whose perimeter has some recesses j, with a radius more larger than the other portions of channel i. The number of recesses / is equal to that of the radial chambers h.
Revenind la regulatorul de presiune D, acesta este format dintr-un prim element tubular 29 in care este ansamblat, prin filetare, un element secundar 30 in lungul axei acestora putând sa alunece o tija culisanta 31 . Intr-o incinta k a elementului secundar 30 este poziționat un arc elicoidal 32 ce se sprijină cu unul din capete pe un disc opritor m al tijei culisante 31.Returning to the pressure regulator D, it is formed by a first tubular element 29 in which a secondary element 30 along their axis is assembled, by threading, which can slide a sliding rod 31. In a chamber k of the secondary member 30 is positioned a helical spring 32 which rests with one of the ends on a stop disk m of the sliding rod 31.
Tija culisanta 31 mai este prevăzută cu niște canale circulare n si o care sunt practicate in dreptul unor găuri filetate p, q si, respective, r. In afara acestor detalii regulatorul de presiune D mai este dotat cu inca niște găuri filetate s si t necesare racordării acestuia la schema hidraulica.Sliding rod 31 may also be provided with circular channels n and o which are practiced against threaded holes p, q and, respectively, r. Apart from these details the pressure regulator D is also equipped with additional threaded holes s and t required its connection to the hydraulic diagram.
Distribuitorul hidraulic B, care este comandat electronic de un computer de bord, nereprezentat, in sine cunoscut si existent de regula pe autovehicul, este prevăzut cu niște canalizatii interioare si cu niște pistoane 33. Admisia uleiului in distribuitorul hidraulic B se face printr-un furtun 34 racordat la regulatorul de presiune D si pătrunde printr-o gaura filetata u intr-un canal vde unde poate ajunge in niște canale wdaca poziția unuia dintre pistoanele 33, dotate cu niște frezari inelare x, permite trecerea uleiului din canalul v intr-unui dintre canalele w. Numărul pistoanelor 33 si respectiv, al (V2 0 10-00924-Ο 1 -10- 2010The hydraulic distributor B, which is electronically controlled by an on-board computer, not represented, itself known and existing on the vehicle, is provided with some internal ducts and pistons 33. The oil is admitted through the hydraulic distributor B through a hose. 34 connected to the pressure regulator D and penetrates through a threaded hole u in a vde channel where it can reach in some channels w, if the position of one of the pistons 33, equipped with some ring milling x, allows the passage of the oil from channel v into one of your channels. Number of pistons 33 and respectively of (V2 0 10-00924-Ο 1 -10- 2010
canalelor w corespunde cu numărul de trepte al cutiei de viteze, conform invenției, si desigur cu cel al ambreiajelor hidraulice.of channels w corresponds to the number of gears of the gearbox, according to the invention, and of course with that of hydraulic clutches.
Canalu v corespunde in partea opusa găurii filetate u spre un amortizor hidraulic G al cărui rol este acela de a prelua socul mecanic inițial la schimbarea vitezelor. In aceste situații presiunea de ulei apasa asupra capului unui piston 35 care comprima un arc elicoidal 36 ce preia socul mecanic amintit.Canalu v corresponds on the opposite side of the threaded hole u to a hydraulic shock absorber G whose role is to take over the initial mechanical shock when changing gears. In these situations the oil pressure presses on the head of a piston 35 which compresses a helical spring 36 which takes over the mentioned mechanical shock.
La funcționarea cutiei de viteze, conform invenției, trebuie sa se aiba in vedere faptul ca aceasta este automata, ca autovechiculul nu mai are in acest caz ambreiajul clasic si nici maneta obișnuita a schimbătorului de viteze . Astfel, singura modalitate de punere in mișcare si reglajul vitezei autovehiculului se poate face doar cu ajutorul pedalei de accelerație.When operating the gearbox, according to the invention, it must be borne in mind that it is automatic, as the car does not have in this case the classic clutch or the usual gearshift lever. Thus, the only way of starting and adjusting the speed of the vehicle can only be done with the help of the accelerator pedal.
La pornirea motorului se pune in mișcare de rotatie arborele primar 1 care, prin mecanismul biela-manivela ,pune in funcțiune pompa de ulei A. Aceasta aspira prin furtunul 19 uleiul din regulatorul de presiune D si printr-un alt furtun 37 dintr-un rezervor de ulei 38. De aici uleiul este refulat printr-un furtun 39 pana la regulatorul de presiune D si in același timp, prin furtunul 34, la distribuitorul hidraulic B.When starting the engine, the primary shaft 1 is started to rotate, which, by means of the crank-crank mechanism, starts the oil pump A. It sucks through hose 19 the oil in the pressure regulator D and through another hose 37 in a tank. from oil 38. From here the oil is discharged through a hose 39 to the pressure regulator D and at the same time, through the hose 34, to the hydraulic distributor B.
La creșterea presiunii peste valoarea de funcționare, in circuitul hidraulic, un furtun 40 permite transmiterea presiunii suplimentare din pompa de ulei A spre orificiul filetat s deplasând tija 31 fapt ce duce la obturarea dintre orificiile filetate p si q, ca urmare întrerupe alimentarea pompei de ulei A si asigura o presiune constanta in distribuitorul hidraulic B.When the pressure rises above the operating value, in the hydraulic circuit, a hose 40 allows the additional pressure from the oil pump A to be transmitted to the threaded hole by moving the rod 31, which leads to the sealing between the threaded holes p and q, consequently interrupting the supply of the oil pump. A and ensures constant pressure in the hydraulic distributor B.
La apasarea pedalei de accelerație creste turatia motorului 6 si implicit a arborelui primar 1, iar computerul de bord sesizează depășirea unui anumit număr de rotatii, deschide printr-o electrovalvă 41 legătură dintre canalul v si canalul w corespunzător primei trepte de viteza. In aceasta situație uleiul sub presiune ajunge, prin furtunul 26 in camera de presiune 8 , iar de aici prin canalul fin canalul circular g. De aici se distribuie prin camerele radiale h apsand asupra pistoanelor 27 , iar acestea asupra bilelor 28 care se impaneaza in adânciturile j ale coroanei de cuplare 12 realizând astfel o cuplare rigida intre aceasta si tamburul 9 . Acest contact permite transmiterea puterii de la arborele primar 1 prin dantura b la roata dintata 23, iar c^-2 01 Ο - Ο Ο 9 2 4 - Ο 1 -10- 2010 aceasta fiind solidara cu arborele secundar 20 spre o transmisie finala H, nereprezentata.Pressing the accelerator pedal increases the engine speed 6 and implicitly of the primary shaft 1, and the on-board computer notices the exceedance of a certain number of rotations, opens by a solenoid valve 41 connection between channel v and channel w corresponding to the first gear. In this situation, the oil under pressure reaches through the hose 26 in the pressure chamber 8, and from here through the fine channel the circular channel g. From here it is distributed through the radial chambers h pressing on the pistons 27, and these on the balls 28 which feed into the recesses. j of the coupling ring 12 thus making a rigid coupling between it and the drum 9. This contact allows the transmission of the power from the primary shaft 1 through the gear tooth b to the cogwheel 23, and c ^ -2 01 Ο - Ο Ο 9 2 4 - Ο 1 -10- 2010 this being integral with the secondary shaft 20 towards a final transmission H , not shown.
Comutarea pistoanelor 33, prin electrovalvele 41 si 42 se face de la computerul de bord care actioneaza simultan atat o electrovalva pentru a închide un canal w, permițând eliberarea de sub presiune a ambreiajului precedent prin deschiderea unui alt canal y si a unei găuri filetate z cu traseu spre rezervorul de ulei 38 si o alta electrovalva pentru a deschide alimentarea altui ambreiaj hidraulic.Switching the pistons 33 through solenoid valves 41 and 42 is done from the on-board computer which simultaneously actuates both an solenoid valve to close a channel w, allowing the previous clutch to be released under pressure by opening another channel y and a threaded hole z with route to oil tank 38 and another solenoid valve to open the feed of another hydraulic clutch.
Simultan cu aceasta transmitere a presiunii de la distribuitor hidraulic B spre ambreiajul hidraulic C are loc o scădere a presiunii sub valoarea constanta in dreptul orificiului filetat t fapt ce permite revenirea tijei 31 in poziția inițiala, asigurând alimentarea pompei de ulei A.Simultaneously with this transmission of the pressure from the hydraulic distributor B to the hydraulic clutch C, a pressure drop occurs below the constant value near the threaded hole t, which allows the rod 31 to return to its original position, ensuring the supply of the oil pump A.
Continuând apasarea pedalei de accelerație si crescând in acest fel viteza de deplasare a autovechiculului computerul de bord sesizează creșterea acestei viteze pana la o anumita valoare si transmite un semnal întrerupând electrovalva 41 si cuplând o alta electrovalva 42. In mod similar uleiul sub presiune ajunge acum la camera de presiune 24 de aici la ambreiajul E si in acest fel realizează cuplarea dintre roata 13 si dantura d permițând cuplarea arborelui secundar 20,adica cuplarea celei de a doua trepte de viteza.Continuing to press the accelerator pedal and thus increasing the speed of the car the on-board computer notices the increase of this speed to a certain value and transmits a signal by interrupting the solenoid valve 41 and coupling another solenoid valve 42. Similarly, the pressure oil now reaches the pressure chamber 24 from here on the clutch E and in this way realizes the coupling between the wheel 13 and the gear d allowing the coupling of the secondary shaft 20, that is to say the coupling of the second gear.
In același mod prin decuplarea unei electrovalve si cuplarea celeilalte alaturate, in sens crescător sau descrescător a vitezei, se poate trece de la o treapta de viteza la alta.In the same way, by decoupling one solenoid valve and coupling the other side, in an increasing or decreasing direction of speed, one can switch from one gear to another.
