CLASS INTERNATIONAL SWEDISH F 06h47h: 13 PATENT AND REGISTRATION AGENCY Ans. 8167/1958 was received on 29/8 1958 issued on 16/12 1963 EP BULLARD HI, STONY CREEK, CONN., USA Stepless adjustable gear unit Priority requested (ran on 30 August 1957 (USA) The present invention relates to a steplessly adjustable transmission with power transmission carriages between a preferably continuously driven input shaft and an output shaft, including first and second interconnectable planetary shafts, which are alternatively connectable in their respective power transmission carriages and the input part of which is in constant driving engagement with the input shaft, and a unit with stepless control. of the speed of the planetary waxes.

,Uppfinningen syftar i forsta hand till alt astadkomma en transmission av delta slag, vid vilken den forsta planetvaxeln är oberoende av den andra planetvaxeln Over ett visst utgangsvarvtalsonulde, medan samtidigt den forsta planetvaxeln konditionerar den andra planetvaxeln, s. att den senare utan effektforlust till foljd av friktion kan overtaga kraftOverforingen fran den forsta och giva ett annat varvtalsomrade an det medelst den forsta planetvaxeln erhalln.. Under det att transmissionen arbetar i detta andra utgangsvarvtalsomrade, konditioneras den forsta planetvaxeln genom den andra planetvaxelns drift. The object of the invention is primarily to provide a transmission of the delta type in which the first planetary gear is independent of the second planetary gear Over a certain output speed ode, while at the same time the first planetary gear condition the second planetary gear, so that the latter without loss of power of friction can take over the power transmission from the first and give a different speed range than that obtained by the first planetary gear. While the transmission is operating in this second output speed range, the first planetary gear is conditioned by the operation of the second planetary gear.

Det kanneteanande -vid den steglast reglerbara transmissionen enligt uppfinningen bestir dari, att utgangsaxeln an kopplingsbar fOr att drivas av valbar planetvaxel i ett for resp. kraftiiverforingsvag forutbestamt varytalsomrade, i vialket varvtalet är reglerbart av enheten med steglOst reglerbart varvtal, och att varvtalsomradena aro sa valda, att utgangsforbindningar frau bagge planetvaxlarna vid ett speciellt varvtal has enheten med steglOst reglerbart varvtal ha huvudsakligen samma varvtal fOr medgivande av direkt hop koppling av utgangsaxeln med endera av planetvaxlarna, och utgangsaxelns forbindning ãr omstallbar frau den ena planetvaxeln till den andra planetvaxeln vid den tidpunlit, cid enheten med steglOst reglerhart varvtal ger en ringa skillnad i relativ rotation mellan utgangsforbindningarna, varefter utgangsaxeln är kopplad fOr att drivas av den andra planetvaxeln i dess motsvarande varvtalsomrade, i vilket varvtalet likaledes är reglerbart av enheten med steglOst reglerbart varvtal. The characteristic of the step-load-adjustable transmission according to the invention consists in the fact that the output shaft can be switched to be driven by a selectable planetary shaft in a direction resp. power supply wave predetermined speed range, in which the speed is controllable by the unit with steplessly adjustable speed, and that the speed ranges are so selected that output connections from the planetary gear shafts at a special speed have the unit with steplessly adjustable speed have substantially the same speed with either of the planetary shafts, and the connection of the output shaft is switchable from one planetary shaft to the other planetary shaft at that time, cid unit with stepless control speed gives a small difference in relative rotation between the output connections, after which the output shaft is coupled to the other shaft its corresponding speed range, in which the speed is likewise controllable by the unit with steplessly adjustable speed.

Uppfinningen forklaras narmare i det fOljande med hainvisning till bifogade ritning, pa vilken den ensamma figuren dr en sehematisk bild .av en transmission med variabelt varytal jamte regleranordning till derma, varpa. principerna enligt uppfinningen ha tillampats. The invention is explained in more detail below with reference to the accompanying drawing, in which the single figure draws a sehematic picture of a transmission with variable speed as well as control device for this, warp. the principles of the invention have been applied.

Med hanvisning till ritningen kan en ingangsaxel 10 medelst lamplig anordning, exempelvis kugghjul 11 och 12, vara forbunden med en kraftanaskin, exempelvis en vaxelstromsmotor 13 med konstant varvtal. Ingangsaxeln 10 kan vara fOrbunden med ett forsta element i en planetvaxel D, vilken dr belagen i en kraftflodesvag. I det visade utforandet ar axeln ,forbunden med ett soldrev 14, men det ar uppenbart, att vilket som heist av planetvaxelns D tre krafttiverforande element kunde ha valts. With reference to the drawing, an input shaft 10 can be connected by means of a lamp device, for example gears 11 and 12, to a power machine, for example an alternating current motor 13 with a constant speed. The input shaft 10 may be connected to a first element of a planetary shaft D, which is coated in a weak power wave. In the embodiment shown, the shaft is connected to a solar gear 14, but it is obvious that any of the three power-carrying elements of the planetary shaft D could have been selected.

En cylindrisk kuggvaxel, innefattande kugghjul 15, 16 och 17, visas driva en axel 18 fran axeln. 10 i samma riktning som axeln 10, men rotationsriktningen hos axeln 10 relativt, axeln 18 ar ovasentlig, sasom kommer att forklaras i det foljande. Axeln 18 dr .Thrbunden med ett fOrsta element i en annan planetvaxel C, som hr belagen i en annan kraftflodesvag. Axeln 18 kan vara forbunden med vilket som heist 2— — av de Ire kraftoverforande elementen i planetvaxeln G och visas fOrbunden med ett soldrev 19 i denna planetvaxel. A cylindrical gear shaft, including gears 15, 16 and 17, is shown driving a shaft 18 from the shaft. 10 in the same direction as the axis 10, but the direction of rotation of the axis 10 relative, the axis 18 is insignificant, as will be explained in the following. Axis 18 dr .Thrbunden with a first element in another planetary axis C, which is coated in another power flood weak. The shaft 18 can be connected to any of the lift-transmitting elements of the planetary gear G and is shown connected to a solar gear 19 in this planetary shaft.

Axeln 18 Sr darjamte forbunden med en tvangsmassigt deplacerande hydraulisk enhet 20 med vartabel volym, varvid denna enhets variabla deplacement kan andras genom installning av en havarm 21 mellan tvh granslagen, i vilka enheten 20 avgiver vitska under tryek vid maximal kapacitet i motsatta stromningsriktningar. Da havarmen 21 Sr i mittlaget for sin rorelse, avgives joke nagon vatska av enheten 20. The shaft 18 is further connected to a forcibly displacing hydraulic unit 20 of variable volume, whereby the variable displacement of this unit can be changed by installing a sea arm 21 between the two branches, in which the unit 20 emits whitening under pressure at maximum capacity in opposite flow directions. When the sea arm 21 Sr in the middle layer for its movement, the joke is given some water by the unit 20.

,Enheten 20 kan vara av vilken tvangsmassigt deplacerande typ med variabel kapacitet som heist och den kan vara forbunden med en tvangsmassigt deplacerande icke-variabel hydraulisk enhet 22 i en sluten krets, innefattande ledningar 23 och 24. Enheten 22 kan vara farbunden med en axel 25 genom varytalsreducerande kugghjul 23' och 24' for ett andamal, vilket senare kommer att beskrivas. Ett kugghjul 26 kan vara fast vid axeln 25. Kugghjulet 26 kan ingripa med ett kugghjul 27, som Sr monterat pa ett andra element 27' I planetvaxeln D, och kugghjulet 27 kan ingripa med ett kugghjul 28 ph ett andra element 28' i planetvaxeln G. The unit 20 may be of any variable capacity forcibly displacing type as heist and it may be connected to a forcibly displacing non-variable hydraulic unit 22 in a closed circuit, comprising lines 23 and 24. The unit 22 may be connected to a shaft 25 by speed reducing gears 23 'and 24' for a second, which will be described later. A gear 26 can be fixed to the shaft 25. The gear 26 can engage with a gear 27, which is mounted on a second element 27 'in the planetary gear D, and the gear 27 can engage with a gear 28 ph a second element 28' in the planetary gear G .

Av det foregaende framgar, att de hydrauliska enheterna 20 och 22 bilda en apparat med steglost reglerbart varvtal, vilken Sr forbunden med ett andra element i vardera av planetvb.xlarna D och C. En hydraulisk apparat med steglost reglerbart varvtal, vilken drives Iran ingangsaxeln 10, har visats, men dot Sr givet, att apparaten med steglost reglerbart varvtal icke hehover vara av den hydrauliska typen eller behover drivas av ingangsaxeln 10. Den kan utgoras av en apparat med steglost reglerbart varvtal av vilket utforande som heist, vilken kan installas i tvh riktningar Over sitt varvtalsregleromrade. Den kan drivas av en. yttre kraftkalla, men da den drives pa sadant satt, erhalles under vissa omstandigheter en forlust av Daterforingseffekb, vilken senare kan nyttiggoras i viss grad och under vissa driftsbetingelser, da apparaten med steglost '7eglerbart varvtal drives fran ingangsaxeln 10. From the foregoing it will be seen that the hydraulic units 20 and 22 form an apparatus with steplessly adjustable speed which is connected to a second element in each of the planetary shafts D and C. A hydraulic apparatus with steplessly adjustable speed which is driven by the input shaft 10. , has been shown, but dot Sr given, that the apparatus with steplessly adjustable speed does not have to be of the hydraulic type or needs to be driven by the input shaft 10. It can be constituted by an apparatus with steplessly adjustable speed of any design, which can be installed in tvh directions Over its speed control range. It can be operated by one. external power cold, but when operated in this way, a loss of Daterforingseffekb is obtained under certain circumstances, which can later be utilized to a certain extent and under certain operating conditions, as the apparatus is operated from the input shaft 10 with stepless adjustable speed 10.

De andra elementen 27' och 28' i planetva.xlarna D och C roteras i motsatta riktningar enligt vad som visas ph ritningen, men detta Sr blott som exempel och far ieke betraktas som en begransning. Den. enda reservationen ar, att rotation hos de forsta oeh andra elementen i vardera av planetvaxlarna D och C hor vara sadan, att da apparaten 20, 22 phverkas f6r att Oka eller minska i varvtal, varytalet has det tredje kraftoverforande elementet i den ena av planetvaxlarna D eller C &Ur, medan varvtalet hos det tredje elementet i den andra minskar. The other elements 27 'and 28' in the planetary shafts D and C are rotated in opposite directions as shown in the drawing, but this is only as an example and may not be considered as a limitation. The. the only reservation is that rotation of the first and second elements in each of the planetary shafts D and C should be such that when the apparatus 20, 22 is actuated to increase or decrease in speed, the speed has the third force transmitting element in one of the planetary shafts D or C & Ur, while the speed of the third element in the second decreases.

I det visade utforandet kan det tredje elementet i planetvaxeln D utgoras av en axel 29 med en arm 30, varvid ett planetdrev 31 Sr lagrat i vardera av denna arms yttre andar. Planetdreven 31 ingripa 'givetvis med soldrevet 14 liksom med invandiga kuggar 32 pa. planetvaxelns D andra element 27'. In the embodiment shown, the third element in the planetary shaft D can be constituted by a shaft 29 with an arm 30, a planetary gear 31 Sr being mounted in each of the outer spirits of this arm. The planetary gears 31 intervene, of course, with the solar gear 14 as well as with internal teeth 32 pa. the second element 27 'of the planetary gear D.

Det tredje elementet i planetvaxeln C kan utgoras av en axel 33, vilken utgor motsvarighet till axeln 29 och liar en arm 34, pa vilken planetdrev 35 aro lagrade, vilka ingripa med soldrevet 19 och invandiga kuggar 36 pa det andra elementet 28'. The third element in the planetary shaft C may be constituted by a shaft 33, which corresponds to the shaft 29 and has an arm 34, on which planetary gears 35 are mounted, which engage with the solar gear 19 and internal teeth 36 on the second element 28 '.

Olika kuggvaxlar kunna vara anordnade mellan axlarna 29, 33 och en. utgangsaxel 37. Dessa kuggvaxlar kunna innefatta ett cylindriskt kugghjul 38, som Sr fast vid axeln 33 och ingriper med ett kugghjul 39, vilket Sr lagrat pa axeln 37, samt ett kugghjul 40, vilket Sr fast vid axeln 29 och befinner sig i ingrepp med ett kugghjul 41, som Sr lagrat pa axeln 37. Individuellt paverkbara kopplingselenaent 12 och 43 kunna vara anbragta pa axeln 37 medelst bommar och spar och kunna samverka med kopplingsorgan p5 kugghjulet 39 resp. kugghjulet 41 ph senare beskrivet satt. Different gear shafts can be arranged between the shafts 29, 33 and one. output shaft 37. These gears may comprise a cylindrical gear 38, which is fixed to the shaft 33 and engages with a gear 39, which is mounted on the shaft 37, and a gear 40, which is fixed to the shaft 29 and is engaged with a gears 41, which are mounted on the shaft 37. Individually actuable coupling elements 12 and 43 can be mounted on the shaft 37 by means of booms and grooves and can co-operate with coupling means on the gear 39 resp. gear 41 ph later described sat.

FOr att b5.st visa det avsedda sattet for drift av transmissionen med variabelt varvtal skola vissa rent godtyckliga varden lamnas for de olika komponenterna. Foljande kuggantal pa de olika kugghjulen .komma att anvandas i det exempel, som skall beskrivas. In order to show at least the intended mode of operation of the variable speed transmission, certain purely arbitrary values must be left for the various components. The following number of gears on the various gears will be used in the example to be described.

Gears Cogs Gears Cogs Gears Cogs 11 - 19 - - 12 - 26 - 36 - 60 14 - 27 - 80 38 - 15 - 28 - 80 39 - 16 - 31 - - 17 - 32 - 60 41 - 23 '12 24' - 27 With the turnover ratios above and with the input shaft 10 rotating at, for example, 1800 r / m and because the gear ratio is the same for both planetary shafts, the base speed for each planetary gear is: BS --- (speed of the solar gear), so r and s are the teeth 32 rasp. cogs ph drive 14.

. • . B. S. (1800) = 450 r/gn. (med 60+ elementet 27' fast). . •. B. S. (1800) = 450 r / gn. (with 60+ element 27 'fixed).

Om .det ,antages, att man onskar ha axeln 29 att rotera med 150 r/m Over och under basvarvtalet pa 150 r/m, blir varvtalet hos elementet 27' for erhallandet av dessa + 150 rim hos axeln 29: + 150 = r (varvtal hos elementet 27') r +s 60 + 150 =(varvtal hos 27') 60+ — —3 Varvtalet hos 27' = + 150 X 4/3 = + 200 Faljnktligen skall axeln. 25 rotera med + 200 X —80 = + 800 r/m. 20 — Av det foregaende framgar, att de hydrau.- liska enheterna 20 och 22 kunna valjas pa sadant satt, att da. enheten 20 drives med 1800 r/m frau ingfingsaxeln 10 med sin havarm 21 nara men icke helt vid installningsgranserna (for ett andamal, som senare skall beskrivas), enheten 22 kommer att rotera med 1800 rim och den sistnanmda enheten kommer att driva axeln 25 med + 800 r/m over reduktionsvaxeln 2:3' .och 21'. If it is assumed that it is desired to have the shaft 29 rotate at 150 r / m above and below the base speed of 150 r / m, the speed of the element 27 'for obtaining these + 150 rims of the shaft 29 becomes: + 150 = r (speed of the element 27 ') r + s 60 + 150 = (speed of 27') 60+ - —3 Speed of 27 '= + 150 X 4/3 = + 200 Rotate with + 200 X —80 = + 800 r / m. 20 - It follows from the foregoing that the hydraulic units 20 and 22 can be selected in such a way that da. the unit 20 is driven with 1800 r / m frau ingfing shaft 10 with its sea arm 21 near but not completely at the installation boundaries (for a second purpose, to be described later), the unit 22 will rotate with 1800 rims and the latter unit will drive the shaft 25 with + 800 r / m over reduction shaft 2: 3 '.and 21'.

Axeln 33 eller 29 i den planetvaxel C eller D, i vilken reaktionselementet 27' eller 28' roterar I motsatt riktning mot plantvaxelns soldrev, kommer att rotera med 450 — 150 = 300 r/m, och den andra axeln kommer att rotera med 450 + 150 = 600 r/m, emedan dess reaktionselement roterar i samma riktning som det motsvarande soldrevet. The shaft 33 or 29 of the planetary shaft C or D, in which the reaction element 27 'or 28' rotates in the opposite direction to the solar gear of the plant shaft, will rotate at 450 - 150 = 300 r / m, and the other shaft will rotate at 450 + 150 = 600 rpm, because its reaction element rotates in the same direction as the corresponding solar gear.

Av det foregaende framgar, att varvtalen hos reaktionselementen 27' och 28' icke variera relativt varandra men att elementen 27' och 28' rotera i motsatta riktningar. Vidare frank*, att soldreven 11 oak 19, som bilda de forsta elementen i planetvaxLarna C och D, rotera med samma varvtal i samma riktning. Da enheterna 20 och 22 installas for okning av varvtalet hos axeln 29, minskar foljaktligen varvtalet hos axeln 33, och da axeln 29 arbetar med sitt hogsta varvtal, och vice versa. From the foregoing it appears that the speeds of the reaction elements 27 'and 28' do not vary relative to each other but that the elements 27 'and 28' rotate in opposite directions. Further frank *, that the solar gears 11 oak 19, which form the first elements in the planetary shafts C and D, rotate at the same speed in the same direction. Consequently, as the units 20 and 22 are installed to increase the speed of the shaft 29, the speed of the shaft 33 decreases, and as the shaft 29 operates at its highest speed, and vice versa.

Med de rotationsriktningar, som markerats pa ritningen, och med havarmen 21 i dess med heldragna linjer visade lage nara det ena granslaget for densamma roterar axeln 33 med 300 r/m och axeln 29 med 600 r/m. Med kopplingen 42 1 ingrepp och kopplingen. 43 ur ingrepp roterar axeln 37 med 150 r/m, di kugghjulens 38 och 39 utvaxlingsforhallande ãr 1:2. Da havarmen 21 fOrskjutes till sitt lige 2, komma hada axlarna 29 och 33 att rotera med basvarvtalet pa 450 r/m och axeln 37 att rotera flied 225 r/m. With the directions of rotation marked in the drawing, and with the sea arm 21 in its position shown in solid lines near one of its branches, the shaft 33 rotates by 300 r / m and the shaft 29 by 600 r / m. With the coupling 42 1 engagement and the coupling. 43 out of engagement, the shaft 37 rotates at 150 rpm, in the gear ratios 38 and 39 gear ratio 1: 2. As the sea arm 21 is displaced to its straight 2, the shafts 29 and 33 will rotate at a base speed of 450 rpm and the shaft 37 will rotate at a speed of 225 rpm.

Genom .omstallning av havarmen 21 till dess 'age 3 nara det andra granslaget for havarmen bringas axeln 27 att rotera med 300 r/m, som ãr varvtalet hos axeln 29 och kugghjulet 41, till foljd av att utvaxlingsforhallandet Indian kugghlulen 40 och 41 är 1: 1. FOljaktligen kan kopplingen 43 bringas i ingrepp, medan kopplingen 42 forblir i ingrepp, till foljd aw kugghjulens 39 och 41 synkrona varvtal. Sedan kopplingen 43 bragts helt I ingrepp med kugghjulet 41, kan kopplingen 42 bringas ur ingrepp med kugghjulet 39. By shifting the gear arm 21 to its age 3 near the second branch of the gear arm, the shaft 27 is caused to rotate at 300 rpm, which is the speed of the shaft 29 and the gear 41, due to the fact that the gear ratio Indian gears 40 and 41 are 1 : 1. Consequently, the clutch 43 can be engaged, while the clutch 42 remains engaged, following the synchronous speeds of the gears 39 and 41. After the clutch 43 has been fully engaged with the gear 41, the clutch 42 can be disengaged from the gear 39.

Man erinrar sig, att axeln 29 roterar med 300 rim och att dess varvtal kan okas till 600 r/m genom Aterforing av havarmen 21 till ett lige nara dess lage 1. It is recalled that the shaft 29 rotates by 300 rims and that its speed can be increased to 600 rpm by returning the sea arm 21 to a level close to its position 1.

Det är vid det visade utforandet tydligt, att kopplingen 42 bar forbindas med kugghjulet 39 ,och kopplingen 43 bringas ur ingrepp med kugghjulet 41, dA havarmen 21 till att b5rja med fir nara sitt ovre, med heldragna linjer visade lage, och att kopplingen 43 forst bor forbindas med kugghjulet 41 och kopplingen 12 darefter bringas ur ingrepp med kugghjulet 39, db.' havarmen 21 ar nara sitt nedre, med streckad linje visade lage, fOr fOrhindrande av att ett tillstand uppstar, i vilket kraftoverf5- ringsvagen till utgangsaxeln 37 Si halt avbruten. In the embodiment shown, it is clear that the clutch 42 can be connected to the gear 39, and the clutch 43 is brought out of engagement with the gear 41, when the sea arm 21 begins to move close to its upper, with solid lines shown, and that the clutch 43 first should be connected to the gear 41 and the clutch 12 is subsequently disengaged from the gear 39, db. the sea arm 21 is close to its lower, dashed line shown position, in order to prevent a condition from arising in which the power transmission carriage to the output shaft 37 Si is interrupted.

F6r sakerstallande av att kopplingsorganen mellan kugghjulen 41, 39 och kopplingarna 13, 42 ga i ingrepp med varandra pi ratt satt utan ber5ring kb o mot kb, oak for sakerstallande av att kopplingen 43 trader i verksamhet oak att kopplingen 42 avlastas, innan den sistnamnda kopplingen bringas ur ingrepp, och vice versa, har en regleranordning for transmissionens manovrering astadkommits. Den kan innefatta en kopplingsspak 44, vilken ar forbunden med en kolvstang 45, sem stracker sig in i 'en cylinder 46, i vilken en kolv 47 ar anordnad att forskjutas fram och Ater. De effektiva areorna hos kolvens 47 bada sidor kunna vara lika stora. For the fact that the coupling means between the gears 41, 39 and the couplings 13, 42 engaged with each other on the steering wheel sat without contact kb o against kb, nor for the fact that the coupling 43 enters into operation even that the coupling 42 is relieved, before the latter coupling disengaged, and vice versa, a control device for maneuvering the transmission has been provided. It may comprise a coupling lever 44, which is connected to a piston rod 45, which extends into a cylinder 46, in which a piston 47 is arranged to be displaced forward and Ater. The effective areas of both sides of the piston 47 can be equal.

En tannan kopplingsspak 49 kan vara forbunden med kopplingen 43, och den kan vara forbunden med en kolvstang 50, som stracker sig in i en cylinder 51, i vilken en kolv 52 ar anordnad att forskjutas fram och filer. De effektiva areorna hos motsatta sidor av kolven 52 kunna likaledes vara lika stora. A toothed coupling lever 49 may be connected to the coupling 43, and it may be connected to a piston rod 50, which extends into a cylinder 51, in which a piston 52 is arranged to be displaced and files. The effective areas of opposite sides of the piston 52 may likewise be equal.

De motsatta andarna av cylinder. 46 Oro genom ledningar 55 och 56 forbundna med en ventilkammare 57, i vilken ett hantelformat ventilorgan 58 ar anordnat att forskjutas fram och ater, varvid detta ventilorgan visas alastiskt belastat mot vanstra anden. av kammaren 57 medelst en fjader 59.

Emedan. cylinderns 46 va.nstra ande da ar i forbindelse med en utloppsoppning 73, fOrskjutes kopplingen 42 ur ingrepp med kugghjulet 39. Tillforseln av strain till solenoiderna 67 och 68 ãr avsedd att astadkommas i en serie regleroperationer, vilka skola beskrivas senare. With the dumbbell-shaped valve means 58 and 63 are pre-barred rods 65 and 66, which are actuated by means of solenoids 67 and 68. A pressure fluid inlet 69 connects the chambers 57 and 62 to each other. In the position of the valve means 58 and 63, shown in the drawing, pressure fluid from the inlet 69 passes through the lines 56 and 61, whereby engagement is effected between the coupling 42 and the gear 39, while the coupling 13 is disengaged from the gear 41. The right spirits of the cylinders 46 and 61 std. In connection with outlet openings 70 and 71. By supplying current to the solenoid 68, the valve member 63 is caused to move to the right of the spring 64, after which pressure fluid passes from the inlet 69 through the line 60 to the hollow node of the cylinder 51. Since the left end of the cylinder 51 now communicates with an outlet opening 72, the coupling 43 is displaced into engagement with the gear 41. As the solenoid receives current, the valve member 58 is pushed to the right against the action of the spring 59, after which pressure fluid = passes from the inlet 69 through the conduit 55 to the Nigra spirit of the cylinder 46. Emedan. the left end of the cylinder 46 in connection with an outlet opening 73, the coupling 42 is displaced out of engagement with the gear 39. The supply of strain to the solenoids 67 and 68 is intended to be effected in a series of control operations, which will be described later.

Omstallningen av havarmen 21 mellan dess rorelsegranser kan astadkommas genom svangning av en havstang 74, vilken är forbunden med en installbar svangtapp 75. Havstangen 74 är anordnad med en slits 76, vilken samverkar med ett drivorgan 77, som ãr fast vid en slade 78, vilken kr anordnad att forskjutas fram och ater langs styrningar 79, 80. En kamfoljare 81, som iir lagrad pa en tapp, vilken är fast vid sladens 78 oversida, glider i ett kamspar 82 i periferin ay en trumformig kam 83, vilken kan vara fast vid en roterbar axel 84. Axeln 84 kan vara fast vid ett snackhjul 85, som ãr anordnat att roteras ;iver nagot mindre an 3600 i en riktning fram och en riktning back och mars rotation begransas av ett stopporgan 86 och ett fast anslag 86'. The rearrangement of the sea arm 21 between its movement boundaries can be effected by pivoting a sea rod 74, which is connected to an installable pivot pin 75. The sea rod 74 is provided with a slot 76, which cooperates with a drive means 77, which is fixed to a slide 78, which A cam follower 81, which is mounted on a pin, which is fixed to the upper side of the cord 78, slides in a pair of cams 82 in the periphery of a drum-shaped cam 83, which may be fixed at a rotatable shaft 84. The shaft 84 may be fixed to a sprocket 85, which is arranged to rotate slightly less than 3600 in a forward direction and a direction of reverse and reverse rotation is limited by a stop member 86 and a fixed stop 86 '.

En. kamaxel 87 kan drivas fran axeln 84 med en utvaxling pa. 1: 2 medelst koniska kugghjul 88 och 89. Kammar 90, 91, 92 och 93 kunna vara fasta vid axeln 87 och anordnade relativt stromstallare 94, 95, 96, 97, 98 och 98' pa det salt, som visas pa ritningen. One. camshaft 87 can be driven from shaft 84 with a gear ratio of. 1: 2 by means of bevel gears 88 and 89. Combs 90, 91, 92 and 93 may be fixed to the shaft 87 and arranged relative to switches 94, 95, 96, 97, 98 and 98 'on the salt shown in the drawing.

Med apparaten i detpA ritningen visade tillstandet erhaller motorn 13 sham vid tillslagningen ay en stromstallare 99', varigenom den hydrauliska enheten 20 bringas att avgiva huvudsakligen maximal vatskevolym till den hydrauliska enheten 22, for att den senare skall bringas att rotera axeln 25 med 800 r/m. Stopporganen for begransning 'av havarmens 21 maximala rorelse aro sh' installda, att axeln 25 kan bringas att rotera nagot fortare An. ± 800 rim ay en anledning, som shall forklaras i det foljande. Med axeln 25 roterande med 800 r/m roterar axeln. 33 med 300 rim och axeln 29 med 600 rim. Emedan kopplingen 42 ar i ingrepp och kopplingen 43 är ur ingrepp, roterar axeln 37 med 150 r/m. With the apparatus shown in the drawing shown in the drawing, the motor 13 receives sham on switching on a current switch 99 ', whereby the hydraulic unit 20 is caused to deliver substantially maximum volume of liquid to the hydraulic unit 22, so that the latter is caused to rotate the shaft 25 by 800 r / m. The stop means for limiting the maximum movement of the sea arm 21 are set so that the shaft 25 can be caused to rotate somewhat faster. ± 800 rhyme ay a reason, which shall be explained in the following. With the shaft 25 rotating at 800 rpm, the shaft rotates. 33 with 300 rhymes and the shaft 29 with 600 rhymes. While the clutch 42 is engaged and the clutch 43 is out of engagement, the shaft 37 rotates at 150 rpm.

Med stopporganet 86 pa axeln 84 i anliggning mot de fasta anslaget 86' ar stromstallaren 96 tillslagen och stromstallaren 97 franslagen. Med stromstallareu 97 franslagen medfor tillslagning av en backstartstromstallare 100 icke aktivering av ett motorrela MR. Tillslagning ay en stromstallare 101 medfor aktivering av ett motorrela MF, varigenom stramstallare F, F i en motors 102 krets slas till, varvid denna motor driver snackhjulet 85 Over en snackskruv 103. Genom aktivering ay motorrelaet MF Oppnas darjamte normalt slutna kontak- ter MF-1 i kretsen for motorrelaet MR. Genom aktivering ay motorrelaet MF slutas darjamte normalt oppna kontakter MF-2, vadge- nom solenoiden 99 erhaller strom for place- ring av svangtappen 75 i det visade laget, I vilket havarmen 21 har kortare svangningsbage An som erfordras for att enheten 20 skall bringas att arbeta med sin maximala kapacitet, varfOr axeln 25 roterar med ett varvtal, som är nagot mindre An 800 rim, da havarmen 21 ar i sitt lage 3. With the stop member 86 on the shaft 84 abutting the fixed abutments 86 ', the switch 96 is turned on and the switch 97 is turned on. With the power switch 97 turned off, turning on a backstart switch 100 does not activate a motor-relay MR. Switching on a switch 101 entails activating a motor relay MF, whereby switches F, F in a motor 102 circuit are switched on, this motor driving the snack wheel 85 over a screw screw 103. By activating the motor relay MF, normally closed contacts MF- are opened. 1 in the circuit for the motor relay MR. By activating the motor relay MF, open contacts MF-2 are normally closed, as a result of which the solenoid 99 receives current for placing the pivot pin 75 in the layer shown, in which the sea arm 21 has a shorter pivot bag An which is required for the unit 20 to be brought to work with its maximum capacity, for which the shaft 25 rotates at a speed which is slightly less than 800 rims, since the sea arm 21 is in its position 3.

Da motorn 102 borjar rotera i en framatriktning, roterar axeln 87 i moturs riktning. As the motor 102 begins to rotate in a forward direction, the shaft 87 rotates in the counterclockwise direction.

Ett land 104 pa kammen 90 medgiver omedelbart tillslagning av strOmstallaren 97, men denna sluter icl(e kretsen for motorreldet MR, emedan de normalt slutna kontakterna MF-1 nu aro oppna. A land 104 on the cam 90 allows immediate switching on of the switch 97, but this closes in the circuit of the motor fire MR, since the normally closed contacts MF-1 are now open.

Da. axeln 84 roterar, glider kamfoljaren 81 I kammens 83 spar 82, varigenom sladen 78 f5rskj utes nedat. Darigenom rforskjutes ha.varmen 21 mot sitt lage 2, sa att axeln 37 bringas att Oka i varvtal fran 150 r/m till 225 r/m, da havarmen 21 nar sitt lage 2, alit sasom tidigare beskrivits. Yes. the shaft 84 rotates, the cam follower 81 slides in the groove 82 of the cam 83, whereby the slide 78 is moved downwards. As a result, the sea heater 21 is displaced towards its bearing 2, so that the shaft 37 is caused to increase in speed from 150 r / m to 225 r / m, as the sea arm 21 reaches its bearing 2, as previously described.

Fortsatt rotation hos axeln 84 i samma riktning medfar att kammen 83 farskjuter hav- armen 21 till ett lage nara dess lage 3, och om havarmen nadde sitt lage 3, skulle enheten 22 ha bragt axeln 37 att Oka i varvtal till 300 rim och kugghjulet 41 att minska i vary- tal fran 600 till 300 r/m. Som tidigare narants, har emellertid havarmens 21 rorelsebage av- kortats genom placering ay svangtappen 75 i det visade laget. Da kammen 83 liar fOrskjutit havarmen 81 sa langt nedat som mojligt i det visade utfOrandet, har fob aktligen axelns 37 varvtal ieke okat till 300 r/m utan till ett got lagre varde, exempelvis 295 r/m, och har kugghjulet 11 ieke minskat i varvtal till 300 r/m utan till ett varvtal pa exempelvis Foljaktligen finnes en varvtalsskiilnad pa 10 r/m mellan kugghjulet 41 och kopplingen 43, vilken medelst bommar och spar as anbragt pa axeln 37. Continued rotation of the shaft 84 in the same direction causes the cam 83 to push the sea arm 21 to a position close to its position 3, and if the sea arm reached its position 3, the unit 22 would have caused the shaft 37 to increase in speed to 300 rims and the gear 41 to reduce in variants from 600 to 300 rpm. As previously stated, however, the movement bag of the sea arm 21 has been shortened by placing the pivot pin 75 in the team shown. Since the cam 83 has displaced the sea arm 81 as far down as possible in the embodiment shown, the fob 37 axis has actually not increased to 300 r / m but to a good bearing value, for example 295 r / m, and the gear 11 has not decreased in speed to 300 r / m but to a speed of, for example, Consequently, there is a speed difference of 10 r / m between the gear 41 and the clutch 43, which is mounted on the shaft 37 by means of booms and spares.

Vid denna tidpunkt medgiver ett land 105 pa kammen 92, vilken har Milli str5mstallaren 95 franslagen fran starten, att stromstallaren 95 slar till. Genom tillslagningen ay strOmstallaren 95 erhaller solenoiden 68 strom, varvid derma solenoid omstaller yentilorganet 63 at hoger mot fjaderns 64 verkan, varefter tryckvatska passerar genom ledningen 60 och trycker kolven 52 At vans ter, emedan ledningen 51 nu ar forbunden med utloppsoppningen 72. At this time, a land 105 on the cam 92, which has the Milli power switch 95 from the start, allows the power switch 95 to turn on. By switching on the current switch 95, the solenoid 68 receives current, this solenoid switching the spring member 63 to the right against the action of the spring 64, after which pressure water passes through the line 60 and pushes the piston 52 to the left, since the line 51 is now connected to the outlet opening 72.

Foljaktligen fOrskjutes kopplingen 43 till ingrepp med kugghjulet 41, och eftersom det finnes en. varvtalsskillnad pa 10 r/m mellan kugghjulet 41 ,och kopplingen 43, erhalles med — — sakerhet ingrepp, emedan ingrepp fOrhindrande berOring kb o mot klo icke kan uppsta. Consequently, the clutch 43 is displaced into engagement with the gear 41, and since there is one. A speed difference of 10 r / m between the gear 41, and the clutch 43, is obtained with - - safety interventions, since interventions to prevent contact kb o with claw can not occur.

Eftersom kugghjulet 41 roterar ,fortare an kopplingen 43 och emedan kopplingen 42 fortfarande Sr i ingrepp, overfores den kraft, som passerar genom kugghjulet 39 och kopplingen 42, till kugghjulet 41 och kopplingen 43. Det är icke blott denna Overforing som astadkommes, utan till fOljd av att kugghjulet 11 har hogre varvtal an axeln 37, befrias kopplingen 42 fran belastning och skulle, om den. forbleve i ingrepp, medfora lasning av transmissionen. As the gear 41 rotates, faster than the clutch 43 and because the clutch 42 is still engaged, the force passing through the gear 39 and the clutch 42 is transmitted to the gear 41 and the clutch 43. It is not only this transmission which is effected, but as a result because the gear 11 has a higher speed than the shaft 37, the clutch 42 is released from load and would, if it. remained engaged, causing loading of the transmission.

Den ovan forklarade overforingen av kraft'Met sker under kamaxelns 87 rotation mel- lan 900 och nagra fa grader fore den tidpunkt, da ett land 106 pa kammen 91 slar till strom, stallaren 94. Genom att stromstallaren 94 slas till, erhaller solenoiden 67 strom, varige- nom ventilorganet 58 pressas at hoger mot fjaderns 59 verkan. Darigenom bringas vatska att stromma genom ledningen 55, sa att kol- ven 47 pressas at vanster, emedan ledningen 56 nu Sr i fOrbindelse med utloppsoppningen 73. Foljaktligen bringas kopplingen 42 ur in- grepp med kugghjulet 39. linden av landet 105 pa kammen 92 och borjan av landet 106 kammen 91 arc skilda at tillrackligt mycket fOr medgivande av kraftvagens overforing till kopplingen 43 ,och avlastning av kopp- lingen 42. Avstandet mellan de }Ada landen kan bestammas genom experiment. Det Sr up- penbart, att transmissionen lases, ern strom- stallaren 101 skulle slas fran under derma period, da hada kopplingarna 42 och 43 aro i ingrepp med kugghjulen 39 och 41. FOr att for- hindra detta slar ett land 107 pa kammen 93 till stromstallaren 98, vilken i tillslaget lage Sr overksam, undantagandes om stromstalla- ren 101 Sr franslagen under den period, da. kopplingarna 42 och 43 aro verksamma. I ett sadant fall fortsatter motorrelaet MF alt er- hSllafor sakerstallande av att landet 106 blir verksamt for tillslagning av strOm- stallaren 94, sh att kopplingen 12 darigenom bringas ur ingrepp. Av det foregaende .framgar, att det pa kammen 93 anordnade landets 107 langd Sr lika med vinkelavstandet mellan anden av landet 105 pa kammen 92 och borjan av landet 109 pa kammen 91. The transmission of the force explained above takes place during the rotation of the camshaft 87 between 900 and a few degrees before the time when a land 106 on the cam 91 turns on current, the stall 94. By turning on the current switch 94, the solenoid 67 receives current , whereby the valve member 58 is pressed to rise against the action of the spring 59. As a result, liquid is caused to flow through the line 55, so that the piston 47 is pressed to the left, while the line 56 is now connected to the outlet opening 73. Consequently, the coupling 42 is brought out of engagement with the gear 39. the winding of the land 105 on the ridge 92 and the beginning of the country 106 the ridge 91 arc separated that sufficiently to allow the transfer of the power carriage to the clutch 43, and the relief of the clutch 42. The distance between the two countries can be determined by experiment. It is obvious that the transmission is read when the switch 101 was to be switched off during this period, when the couplings 42 and 43 were in engagement with the gears 39 and 41. To prevent this, a land 107 strikes the cam 93. to the current generator 98, which in the turn-on made Sr inactive, except for the current generator 101 Sr the fringe during the period, da. connections 42 and 43 are active. In such a case, the motor relay MF continues to receive the fact that the ground 106 becomes active for switching on the switch 94, so that the clutch 12 is thereby disengaged. From the foregoing it appears that the length of the land 107 arranged on the ridge 93 is equal to the angular distance between the spirit of the land 105 on the ridge 92 and the beginning of the land 109 on the ridge 91.

Vid denna tidpunkt har kammen 83 rote-rat 180° fran det stalle, dar den borjade, och befinner sig sladen 78 i sitt nedersta lage. Genom att stronastallaren 101 halles tillslagen, .ava.gabringas kammens 83 fortsatta rotation. i gamma riktning for att havarmen 21 darigenom skall forskjutas frail sitt lage 3, i vilket axeln 37 roterar med 300 r/m eller hellre exempelvis 305 r/m till fbljd av den. tidigare beskrivna 8verfOringen av kraftvagen .och ay. lastningen av kopplingen 42. Da havarmen 21 Tor sig uppat till sitt lage 2, Okar axelns 37 varvtal till 450 r/m. Genom fortsatt rorelse uppat hos havarmen 21 Okar axelns 37 varvtal till huvudsakligen 600 r/m, varvid landet 104 ph kammen 90 slar frail stromstallaren 96, sh att strommen till motorrclaet MF brytes och kamaxelns 87 rotation stoppas med axeln 37 roterande med sitt maximala varvtal ph huvudsakligen 600 r/m. At this time, the cam 83 has rotated 180 ° from the stall where it started, and the sled 78 is in its lowest position. By keeping the stroller rack 101 on, the continued rotation of the cam 83 is provided. in the gamma direction so that the sea arm 21 is thereby displaced from its bearing 3, in which the shaft 37 rotates at 300 r / m or rather, for example, 305 r / m as a result thereof. previously described 8verfOringen av kraftvagen .och ay. the loading of the clutch 42. When the sea arm 21 rises to its position 2, the speed of the shaft 37 increases to 450 r / m. By continuing to move upwards at the sea arm 21, the speed of the shaft 37 increases to substantially 600 r / m, whereby the land 104 ph cam 90 turns off the current generator 96, so that the current to the motor shaft MF is interrupted and the rotation of the cam shaft 87 is stopped with shaft 37 rotating at its maximum speed ph mainly 600 r / m.

For reducering av axelns 37 varvtal slas strOmstallaren 100 till, och emedan stromstal- laren 97 nu Sr tillslagen, erhaller motorrelaet MR strom. DS reldet MR erhaller strain, Oppnas de normalt slutna kontakterna MR-1 och slutas de normalt oppna kontakterna MR-2. Genom att kontakterna MR-1 oppnas, forhindras tillforsel av strom till motorrelaet MF, om stromstallaren 101 skulle slas till. Genom att kontakterna MR-2 slutas, erhaller solenoiden 100' strom, varvid svangningspunkten 75 ror sig till sitt ,hOgra lage 75', vilket har till foljd att havarmens 21 rorelse under den foljande delen av operationscykeln okas fOr i det f81- jande angivet andamal. To reduce the speed of the shaft 37, the switch 100 is switched on, and since the switch 97 is now switched on, the motor relay MR receives power. DS reldet MR receives strain, Opens the normally closed contacts MR-1 and closes the normally open contacts MR-2. By opening the contacts MR-1, the supply of current to the motor relay MF is prevented, should the current generator 101 be switched on. By closing the contacts MR-2, the solenoid 100 'receives current, whereby the pivot point 75 moves to its right position 75', which has the consequence that the movement of the sea arm 21 during the following part of the operation cycle is increased for the following stated purpose. .

,Genom att relaet MR erhaller strain, slatas Sven normalt oppna kontakter RR fOr motorn 102, varigenom denna bringas att rotera i sadan riktning, att kamaxeln 37 roteras i medurs riktning. DS kamaxeln 87 borjar rotera i medurs riktning, slhs strOmstallaren 96 till, men read MF kan icke erhalla strom genom tillslagning ay stromstallaren 101, einedan kontakterna MR-1 nu arc 8ppna. Because the relay MR receives strain, Sven normally opens contacts RR for the motor 102, whereby it is caused to rotate in such a direction that the camshaft 37 is rotated clockwise. The DS camshaft 87 begins to rotate clockwise, the switch 96 is turned on, but the read MF cannot obtain current by turning on the switch 101, since the contacts MR-1 are now open.

Fortsatt rotation hos kammen 83 i den onavanda riktningen medfor p5 nytt forskjutfling av sladen 78 i riktning nedat, varvid hayarmen 21 ror sig neat till sitt lage 2 och axeln 37 minskar i varvtal till 150 r/m. DS havarmen 21 pa nytt narmar sig sitt lage 3, minskar axelns 29 varvtal mot 300 r/m och (Aar axelns 33 varvtal mot 600 r/m. Till f8ljd av utvaxlingsforhallandet ph 2: 1 mellan ku.gghjulen 39 och 38 Okar darf8r kugghjulets 39 varvtal mot 300 r/m. Emedan storleken pa havarmens 21 rorelsebage har okats till foljd av svangtappens 7omstallning St hoger, minska emellertid axeln 29 och kugghjulet 41 i varvtal foal. 300 till exempelvis 295 r/m. I motsvarighet dartill okar kugghjulet 39 i varvtal forbi 300 r/m till exempelvis 305 r/m. Foljaktligen f8refinnes en skillnad pa exempelvis 10 r/m mellan kopplingen 42 och kugghjulet 39, sa att ingreppet mellan dam kan astadkommas utan fara for beroring kb o mot Vid denna tidpunkt i cykeln medgiver landet 106 pa kammen 91 franslagningen av stronastallaren 94, varigenom str8mmen till solenoiden 67 brytes. Darigenom tillates fjadern 59 aterfOra ventilorganet 58 till det pa ritningarna visade laget, i vilket tryckvatska bringas att stromma genom ledningen 56 for att trycka kolven 47 at .1]Oger, emedan ledningen 55 nu star i forbindelse med avloppsoppningen 70. Foljaktligen bringas kopplingen 42 i ingrepp med kugghjulet 39, medan kopplingen 43 forblir i ingrepp med kugghju- 6— — let 41. Emedan, sasom tidigare forklarats, kugghjulet 39 sillier driva kopplingen 42 med exempelvis 305 r/m och kugghjulet 41 soker driva kopplingen 43 med exempelvis 295 r/m, ar det uppenbart, att den kraft, som tidigare passerade genom kugghjulet 41 och kopplingen 43, overfores till kugghjulet 39 och kopplingen 42. Darjamte avlastas kugghjulet 41 och kopplingen 43 under denna period, da hada kopplingarna 42 och 43 aro samtidigt i verksamhet. Continued rotation of the cam 83 in the unusual direction causes a new displacement of the sled 78 in the downward direction, whereby the hay arm 21 does not move to its position 2 and the shaft 37 decreases in speed to 150 r / m. The DS sea arm 21 again approaches its position 3, the speed of the shaft 29 decreases to 300 r / m and the speed of the shaft 33 to 600 r / m. As a result of the gear ratio ph 2: 1 between the gears 39 and 38, the speed of the gear 39 revolutions at 300 r / m. Since the size of the movement arm 21 of the sea arm 21 has been increased as a result of the pivot 7 adjustment St hoger, however, the shaft 29 and the gear 41 decrease in foal speeds. 300 to 295 r / m, for example. speed past 300 r / m to, for example, 305 r / m. Consequently, there is a difference of, for example, 10 r / m between the clutch 42 and the gear 39, so that the engagement between the dam can be effected without danger of contact kb o against At this time in the cycle allows the land 106 on the cam 91 disengages the throttle body 94, thereby interrupting the current to the solenoid 67. This allows the spring 59 to return the valve member 58 to the layer shown in the drawings, in which pressurized liquid is caused to flow through conduits. n 56 to press the piston 47 at .1] Oger, since the line 55 now communicates with the drain opening 70. Consequently, the coupling 42 is brought into engagement with the gear 39, while the coupling 43 remains in engagement with the gear 6— - let 41. Emedan , as previously explained, the gear 39 will drive the clutch 42 at, for example, 305 r / m and the gear 41 will drive the clutch 43 at, for example, 295 r / m, it is obvious that the force which previously passed through the gear 41 and the clutch 43 is transmitted to the gear 39 and the clutch 42. In addition, the gear 41 and the clutch 43 are relieved during this period, when the clutches 42 and 43 were simultaneously in operation.

Under detta intervall har dessutom landet 107 pfi kammen 93 slagit till stromstallaren 98', for att relaet MR fortfarande skall erliana strain, om stromstallaren 100 skulle sifts Wm. During this interval, moreover, the land 107 pfi of the cam 93 has struck the switch 98 ', so that the relay MR will still release strain, should the switch 100 be sifted Wm.

Vid slutet av detta korta intervall astadkommer landet 105 pa kammen. 92 franslagning av stromstallaren 95, varigenom strommen till solenoiden 68 brytes. Darigenom tinkles fj adern 64 aterfora ventilorganet 63 till det pa ritningarna visade laget, i vilket tryckvatska strommar genom ledningen 61 och darvid pressar kolven 52 At Niger, emedan ledningen 60 nu har forbindelse med avloppsoppningen 71. FOljaktligen bringas kopplingen 41 ur ingrepp med kugghjulet 41. At the end of this short interval, the land reaches 105 on the ridge. 92 disengaging the current generator 95, thereby breaking the current to the solenoid 68. Thereby the spring 64 is tinkled to return the valve member 63 to the layer shown in the drawings, in which pressurized water flows through the line 61 and thereby presses the piston 52 At Niger, since the line 60 now has a connection with the drain opening 71.

Fortsatt ornvand rotation hos kammen 83 medfor aterforing av havarmen 21 till dess lage 1, i vilket axeln 37 roterar med 150 r/m. Vid denna tidpunkt har landet 104 pa kammen 90 slagit fran stromstallaren 97, varigenom denna brutit strommen till read MR och stoppat motorn 102. Continued rotation of the cam 83 causes the sea arm 21 to return to its bearing 1, in which the shaft 37 rotates at 150 rpm. At this time, the land 104 on the cam 90 has turned off the current generator 97, thereby breaking the current to the red MR and stopping the motor 102.

Av det foregaende framgar, att stromstallaren 101 kan slas till for att axeln 37 skall bringas att steglost Oka i varvtal till vilket varvtal som heist mellan 150 och 600 r/m, och att axeln 37 efter franslagningen av strEansthllaren 101 fortsatter att rotera med det valda varvtalet. Fran detta valda varvtal kan axeln 37 bringas aft avvika genom att Oka i varvtal eller minska 1 varvtal till vilket onskat varvtal som heist helt enkelt genom att stromstallaren 101 eller 100 Mlles tillslagen, tills det onskade varvtalet uppnatts. From the foregoing it appears that the current generator 101 can be turned on so that the shaft 37 is caused to steplessly increase in speed to any speed which is raised between 150 and 600 r / m, and that the shaft 37 after the release of the current generator 101 continues to rotate with the selected the speed. From this selected speed, the shaft 37 can be deviated from by increasing in speed or decreasing by 1 speed to which desired speed is raised simply by switching on the switch 101 or 100 Mlles, until the desired speed is reached.

Den beskrivna transmissionen har valts i andamal att illustrera uppfinningens prineiper med storsta enkelhet, och ehuru en transmission med steglost variabelt varvtal med ett omrade for utgangsvarvtalet fran 150 rim till 600 r/m vid konstant effekt huvudsakligen over sitt omrfide med avseende pa sin tilllampning pa industriella installationer kan vara i viss man begransad, är det uppenbart, att transmissioner, som tacka vida storre omraden for utgangsvarvtalet fran noll till vary- tal, som ligga Over ingangsvarvtalet och cm- vant, kunna konstrueras med tillampning av uppfinningens principer far att giva konstant effekt vid varje onskat utvaxlingsforhallande. Ehuru de olika dragen hos den nya och forbattrade transmissionen ha visats och beskrivits i detalj i andamal att fullstandigt visa ett utforande av uppfinningen, är det uppenbart, att en mangfald andringar kunna garas med avseende pa forekommande detaljer och att vissa drag kunna finna tillampning utan andra utan att uppfinningens principer frangas. The described transmission has been chosen for the purpose of illustrating the principles of the invention with the greatest simplicity, and although a transmission with steplessly variable speed with a range for the output speed from 150 rims to 600 r / m at constant power mainly over its range with respect to its application to industrial installations may be limited in some respects, it is obvious that transmissions which, thanks to much larger ranges of the output speed from zero to variable, which are above the input speed and cm, can be constructed with application of the principles of the invention to give constant effect. at each desired gear ratio. Although the various features of the new and improved transmission have been shown and described in detail for the purpose of fully illustrating an embodiment of the invention, it is apparent that a variety of modifications may be made to the details which occur and that certain features may be found without others. without compromising the principles of the invention.

Claims

Patent claim: 1. Steplessly adjustable transmission with Ilera PTO shafts between a preferably constant-speed drive input shaft and an output shaft, comprising first and second pivotally connected planetary shafts, which are alternatively connectable in separate PTO shafts and the input part of which is inwardly engaged. , and a unit with steplessly adjustable speed for regulating the speed of the planetary shafts, characterized in that the output shaft (37) can be switched to be driven by selectable planetary gear (E or D) in one for resp. power transmission wave predetermined speed range, in which the speed is adjustable by the unit (20, 22) with stepwise adjustable speed, and that the speed ranges are so selected that output connections (38, 39, 40, 41) Iran bag the planetary gears (C, D) at a special speeds of the steplessly adjustable speed unit (20, 22) have substantially the same speed to allow direct coupling of the output shaft (37) to either of the planetary shafts, and the connection of the output shaft (37) is switchable from one planetary shaft to the other planetary shaft at that time. , as the unit (20, 22) with stepless control speed gives a small difference in relative rotation between the output connections, after which the output shaft is coupled to be driven by the second planetary shaft in its corresponding speed range, in which the speed is likewise controllable by the unit with stepless speed. . Transmission, according to claim 1, characterized in that the output connection (38, 39) for the first planetary gear (C) has a different gear ratio than the supply connection (40, 41) for it. the second planetary gear (D), so that the main salt synchronous speed is achieved between the lathe finger shaft (37) and the output connections, since the output speeds of the planetary gears aro stone resp. less than the base speed Mr the corresponding planetary gear. Transmission according to patent claim 1 or 2, characterized in & tray, that in order to establish the connection between each planetary shaft and the output shaft (37), form-fitting claw couplings (42, 43) are arranged.

Transmission according to patent claim 1, 2 or 3, characterized in that the expressed clutch at the upper speed limit of the unit with steplessly controllable variable is arranged to rotate at a slightly higher speed than the retracted clutch, so that the extended clutch the clutch, when retracted, automatically relieves the retracted clutch to facilitate its deployment.
