Abstract
Trecia lamelová uzávierka diferenciálu radená pod zatažením je určená pre nápravy stavebných, lesných a terénnych vozidiel, kde zlepšuje mobilnost a manévrovatefnosť strojov v teréne s nižšou alebo rozdielnou adhéziou na kolesách nápravy. Očelom riešenia je zlepšenie účinnosti uzávierky diferenciálu a zvýšenie spolehlivosti ovládania uzávierky. Podstata riešenia spočívá v tom, že uzavierací mechanizmus spojky je delený na posuvnú a rotačnú časť, pričom tlakový olej alebo vzduch sa privádza pod posuvnú časť uzaviarecieho mechanizmu uloženú v telese nápravy (5), čím sa dosiahne spofahlivého utesnenia priestoru piestu (3) a tým aj účinnejšieho uzavretiu uzávierkyFriction-type differential lock Shifting under load is designed for axles construction, forestry and off-road vehicles, where it improves mobility and maneuverability machines in the field with lower or different adhesion on the axle wheels. The aim of the solution is to improve the shutter efficiency differential and increase reliability shutter control. The essence of the solution is that it closes the clutch mechanism is divided into a sliding and rotating portion, wherein the pressurized oil or the air is fed under the slide the sealing mechanism stored in the body axle (5), thereby achieving a relieving sealing the piston space (3) and thus more efficiently closing
Description
Vynález rieši treciu lamelová uzávierku diferenciálu, radenú pod zatažením.The invention solves a friction plate lock of a differential, shifted under load.
Známa konštrukcia hydraulickej trecej uzávierky radenej pod zatažením je riešená tak, že mokrá trecia spojka je ovládaná tlakový olejom, privádzaným rotačným prívodom, obmedzeným dvorná piestnymi krúžkami a hriadefovým těsněním po oboch stranách piestnych krúžkov pod piest, ktorý je súčasťou spojky a vylkonáva s ňou rotačný pohyb. V priestoroch medzi piestnymi krúžkami a hriadefovým těsněním sa zachytává olej presiaknutý cez piestne krúžky a odvádza sa potrubím na odpadový systém stroja.The known construction of the hydraulic friction closure under load is designed such that the wet friction clutch is operated by pressure oil, supplied by a rotary inlet, limited by the court piston rings and shaft seal on both sides of the piston rings under the piston, . In the spaces between the piston rings and the shaft seal, the oil seeped through the piston rings is collected and is discharged via a pipe to the machine's waste system.
Nevýhodou takéhoto riešenia je technicky náročné a nespofahlivé utesnenie přívodu tlakového oleja, čo zapříčiňuje zníženie účinnosti uzávierky a vyžaduje si napojenie priestoru presakovania na odpadový systém stroja.The disadvantage of such a solution is the technically demanding and unreliable sealing of the pressurized oil supply, which causes a reduction in the shutter efficiency and requires connection of the leakage area to the machine waste system.
Podstata riešenia trecej lamelovej uzá9 6 vierky podfa vynálezu spočívá v · tom; že piest uzávierky je súčasťou pevného telesa nápravy a je delený na rotačnú a pósuvnú časť, pričom posuvná časť je uložená v telese nápravy a rotačná časť je na nej uložená otočné prostredníctvom ložiska.The principle of the solution of the friction vane closure according to the invention consists in this; The shutter piston is part of a rigid axle body and is divided into a rotary and sliding part, the sliding part being received in the axle body and the rotating part being rotatably supported thereon by a bearing.
Hlavná výhoda takéhoto uloženia piestu spočívá v tom, že posuvná časť uzávierky je možné dokonale těsnit, čím odpadáί nutnost zavedenia okruhu odpadu a· zvyšuje sa účinnost uzávierky a pre ovládanie uzávieriky je možné použit tlaku vzduchu: ?The main advantage of such a piston seating is that the sliding part of the shutter can be perfectly sealed, eliminating the need to introduce a waste circuit and · increasing the efficiency of the shutter and using air pressure to control the shutter:?
Na obr. č. 1 je schematicky uvedený příklad použitia uzávierky podfa vynálezu.In FIG. no. 1 is a schematic example of the use of a shutter according to the invention.
Lamelová uzávierka podfa obr. 1 sa skládá z lamelovej spojky 2 a ovládacieho mechanizmu 1, ktorý sa skládá z piestu 3 tvaru rotačného medzikružia posuvné uloženého v telese valca 7, ktorý je súčasťou telesa nápravy 5. Piest 3 sa skládá z rotačnej časti 4, ktorá je v ňom uložená prostredníctvom ložiska 6.The closure of FIG. 1 comprises a multi-plate clutch 2 and an actuating mechanism 1 which consists of a piston 3 in the form of a rotary annulus slidingly mounted in the cylinder body 7 which is part of the axle body 5. The piston 3 consists of a rotating part 4 which is supported therein bearings 6.
