Abstract

Návrh rieši spojku treoieho uzávěru diferenoiálu, v ktorom poloha náboja voSi vonkajšiemu krytu je zaistená pornocou puzdra zasunutého z jednej strany do vonkajšieho krytu a z druhéj strany má drážku, do ktorej je vložený pružný krůžok. Pružný krážok sa opiera jednou stranou o vložku upevněná v otvore náboja, druhou střetnou sa opiera o Selo náboja,, rádiusové sa opiera o tri skrutky symetricky umiestnené po obvode. Pružný krúžok je zabezpeSený proti otoSeniu pomooou kolika. Vložka má dutinu s priemerom a šířkou umožnujúoou umiestnií do nej pružný krúžok vo voínom stave a otvory umožnujúce vloženie skrutiek. Skrutka mé váloovitú Sasi zakonšená kuželovou Sasiou so skosením, ktoró umožňuje vyvinutie tlaku potřebného na ustálenie polohy pružného krúžku v drážke. Vonkajší kryt má obvodová drážku a otvory privádzajáce tlakové médium do pracovného priestoru pod piest. Vonkajší kryt má dva obvodové kanáliky na umiestnenie tesniaoich krážkov. Výhodou riešenia je zaistenie polohy náboja spojky voči jej vonkajšiemu krytu a jednoduchá montáž a demontáž.The proposal solves the clutch of the third differential lock, in which the position of the hub in the outer casing is secured by a hole of the sleeve inserted from one side into the outer casing and on the other side has a groove into which a spring ring is inserted. The spring ring rests on one side on the insert fixed in the hole of the hub, on the other side it rests on the hub shaft, the radius rests on three screws symmetrically located around the circumference. The spring ring is secured against rotation by means of a pin. The insert has a cavity with a diameter and width allowing the spring ring to be placed in it in a free state and holes allowing the insertion of screws. The screw has a cylindrical shaft terminated by a conical shaft with a bevel, which allows the pressure necessary to stabilize the position of the spring ring in the groove. The outer cover has a circumferential groove and holes supplying the pressure medium to the working space under the piston. The outer cover has two circumferential channels for placing sealing rings. The advantage of the solution is securing the position of the clutch hub relative to its outer cover and easy assembly and disassembly.

Description

Vynález rieSi spojka treoieho uzávěru diferenciálu, hlavně pre polnohospodárske traktory s tlakovým riadením.The present invention provides a clutch of a differential lock, especially for pressure controlled agricultural tractors.

Známa je spojka trecieho uzávěru diferenoiálu, ktorá sa skládá z vonkajšieho krytu, náboja,třecích a opěrných diskov, riadených tlakom piestom. Medostatkom riešenia je, že náboj spojky je osadený z jednej strany vo vonkajšom kryte spojky, z druhej strany na skryte spojky. Udržanie stálej polohy náboja na kryte’sa dosiahne len pomooou pružiny, ·' t .*· * umiestnenej medzi tanierovým kolesom a náhojom, dotláčajúoej náboj do opěrného .puzdra osadeného na kryte.A differential lock friction clutch is known which consists of an outer casing, a hub, friction and support discs controlled by a piston pressure. The solution is that the clutch hub is mounted on one side in the outer clutch housing and on the other side on the clutch housing. Maintaining a constant position of the hub on the cover is achieved only by means of a spring located between the plate wheel and the hatch, pushing the hub into the support sleeve mounted on the cover.

Uvedené nevýhody odstraňuje spojka treoieho uzávěru diferenoiálu, ktorej podstata spočívá v tom, že medzi nábojom a vonkajším krytom je puzdro s drážkou, v ktorej je pružný krúžok. Pružný krúžok Je opretý jednou stranou o vložku zaistenú v otvore náboja pružným krúžkom, drahou stranou je opretý o čelo náboja a rádiusové je opretý o tri skrutky, ktoré sú symetricky rozaiestnené po obvode náboja. Pružný krúžok je zabezpečený proti otočeniu kolíkom.These drawbacks are overcome by the differential lock clutch clutch, which consists in the fact that between the hub and the outer housing there is a sleeve with a groove in which there is an elastic ring. Elastic ring It is supported by one side on the insert secured in the hub hole by the elastic ring, the opposite side is supported on the hub face and radial is supported by three screws, which are symmetrically distributed around the circumference of the hub. The elastic ring is secured against rotation by the pin.

Výhodou vynálezu je zaistenie polohy náboja spojky voči jej vonkajšiemu krytu a jednoduohá montáž a demontáž.The advantage of the invention is to secure the position of the coupling hub relative to its outer housing and to facilitate assembly and disassembly.

Vynález je zobrazený na pripojenom výkrese, kde na obr. 1 je spojka treoieho uzávěru diferenciálu v pozdížnom řeze, na obr. 2 Je rez v rovině A-Λ z obr. 1.The invention is illustrated in the accompanying drawing, in which: FIG. 1 is a longitudinal sectional view of a differential lock threesome; FIG. 2 is a section along line A-Λ of FIG. First

Spojka sa skládá z vonkajšieho krytu 1, náboja 2, trecíoh diskov b a opěrných diskov tlakovo riadených piestom 6. Poloha náboja 2 voči vonkajšiemu krytu 1 Je zaistená puzdrom Puzdro je z Jednej strany zasunuté do vonkajšieho krytu 1, z druhej strany má drážku £, ^do ktorej je vložený pružný krúžok Pružný krúžok £ je opretý jednou stranou o vložku !S, zaistenú v otvore náboja 2 pružným krúžkom 14, druhou stranou je opretý o Selo náboja 2 a rádiusové je opretý o tri skrutky 10, ktoré sú symetricky rozmiestnené po obvode náboja Pružný krúžok 2 J® zabezpečený voči otočeniu kolíkom 13. Vložka 8 má dutinu 15 s priemerom a šířkou umožňujúoou umiestniť do nej pružný krúžok 2 ^{vo v}°í” nom stave. Skrutka 10 má válcovú časť 11 zakončená kužeiov&u časťou 12 so skosením umožnujúoim vyvinutie tlaku potřebného na ustálenie polohy pružného krúžku 2 ^v drážke 2· Vo vonkajšom kryte 1 je drážka 16, v ktorej sú otvory 17 a 18 privádza júce tlakové médium do pracovného priestoru pod piest jS a dva obvodové kanáliky 19 pře umiestnenie tesniaoioh krúžkov.The coupling consists of an outer casing 1, the hub 2, even trecíoh disk drives of the support pressure-driven piston 6. The location of the hub 2 to the outside of the casing 1 is ensured by the sleeve housing is inserted from one side into the outer housing 1, the other side has a groove £, ^the The elastic ring 8 is supported on one side by the insert 10 secured in the hub bore 2 by the elastic ring 14, on the other side by the Selo hub 2 and radially supported by three screws 10 which are symmetrically distributed around the circumference of the hub. The resilient ring 21 is secured against rotation by the pin 13. The insert 8 has a cavity 15 with a diameter and a width allowing the resilient ring 2 to be placed therein ^{in a} larger condition. The bolt 10 has a cylindrical portion 11 terminated by a tapered portion 12 allowing a pressure to be applied to stabilize the position of the elastic ring 2 ^{in the} groove 2. and two circumferential channels 19 for the placement of the sealing ring.
