Abstract

Riešenie patří do oblasti konštrukcie a spůsobu vytvorenia kotúčovej spojky, je určené na použitie u motorových vozidiel na spojovanie a rozpojovanie hnacích a hnaných agregátov. Kotúčovou spojkou a sposobom jej výroby, kde membránová pružina je uložená medzi vekom spojky a oporným krúžkom vylisovaným a vystřihnutým z veka spojky, sa dosiahne rovnoměrné zovretie membránovej pružiny medzi vekom a oporným krúžkom, čím sa vytvoří tuhý celok zaručujúci zachovanie funkčných a úžitkových parametrov spojky pri znižení spotřeby materiálu.The solution belongs to the field of design and method of creating a disc clutch, it is intended for use in motor vehicles for connecting and disconnecting driving and driven units. The disc clutch and the method of its production, where the diaphragm spring is placed between the clutch cover and the support ring pressed and cut out from the clutch cover, achieves uniform clamping of the diaphragm spring between the cover and the support ring, thereby creating a rigid unit guaranteeing the preservation of the functional and utility parameters of the clutch while reducing material consumption.

Description

Vynález sa týká kotúčovej spojky ia spůsobu jej vytvorenia.BACKGROUND OF THE INVENTION The present invention relates to a disc clutch and a method for forming it.

Doteraz známe konštrukčné prevedenia kotúčovej spojky s membránovou pružinou riešia problematiku uloženia membránovej pružiny medzi opornými krúžkami různých konštrukcií. Oporné krúžky sú vyrábané z ocelového drotu, plechu alebo zakrúžením jazýčkov vytvořených z materiálu veka spojky a prechádzajúcich cez otvory membránovej pružiny. Uvedené konštrukcie podopretia membránovej pružiny opornými krúžkami zvyšujú spotřebu materiálu a prácnosť pri výrobě spojky. Druhý sposob pomocou zakrúžených jazýčkov dosahuje maximálně 50 %-né podopretie membránovej pružiny na obvode opornej kružnice, čo má nepriaznivé vplyvy na životnost spojky.So far known design of diaphragm spring disc clutch solves the problem of membrane diaphragm mounting between support rings of different constructions. The support rings are made of steel wire, sheet metal or by curling tongues formed from the clutch lid material and passing through the membrane spring holes. The aforementioned diaphragm spring support structures support the material consumption and labor of the clutch. The second method by means of the curved tongues achieves a maximum of 50% support of the diaphragm spring on the circumference of the support circle, which has adverse effects on the service life of the coupling.

Tieto nevýhody odstraňuje kotúčová spojka a sposob jej vytvorenia pódia vynálezu týlu, že membránová pružina je uložená medzi vekom spojky a oporným krúžkom vylisovaným a vystřihnutým z veka spojky. Podstata vynálezu spočívá v tom, že na veku spojky sa vytvoří prelis přerušený nástrihom u výstužných prelisov pátiek, ktorý sa vo svojom vrchole na opornej kružnici rozstrihne, čím sa súčasne na veku spojky vytvoria patky a budúce oporné hrany veka a oporného krúžku, čím z materiálu veka vznikne budúci oporný krúžok. Po přestřihnutí vytvořeného prelisu sa vnútorné hrany přestřihnutého veka a vonkajšie hrany vystřihnutého oporného krúžku dokalibrujú ohybom a vytvoria tak spolu vzájomný přesah. Veko' spojky a oporný krúžok sú vzájomne ustavené tak, aby otvory pátiek veka spojky a otvory oporného krúžku sa vzájomne překrývali.These drawbacks are eliminated by the disc clutch and the method of forming it according to the invention that the diaphragm spring is disposed between the clutch cover and the support ring molded and cut out of the clutch cover. The essence of the invention is that a cut is formed on the clutch cover interrupted by a cut in the reinforcement overhangs of the frets, which is cut at its apex on the support circle, thereby forming the beads and the future supporting edges of the lid and the support ring at the clutch lid. the age of the next support ring. After cutting the preform, the inner edges of the cut lid and the outer edges of the cut-out support ring are calibrated by bending to form a mutual overlap. The clutch cover and the support ring are aligned with each other such that the closure hole openings of the clutch cover and the support ring openings overlap each other.

Hlavně výhody kotúčovej spojky a sposobu jej vytvorenia pódia vynálezu spočívajú v tom, že ohybom dokalibrované hrany vytvoria oporné hrany veka spojky a oporného krúžku, ktoré zaručujú minimálně 75 %-né podopretie membránovej pružiny na obvode opornej kružnice veka spojky, ako i týmto sposobom vytvořeného oporného krúžku, čo má priaznivý vplyv na životnost spojky pri znížených materiálových nákladech.In particular, the advantages of the disc clutch and the method of forming it according to the invention consist in that the bent-calibrated edges form the support edges of the clutch cover and the support ring, which guarantee at least 75% support of the diaphragm spring on the circumference of the support circle of the clutch lid as well as the support formed in this way. ring, which has a beneficial effect on the service life of the clutch at reduced material costs.

Kotúčová spojka a sposob jej vytvorenia podía vynálezu je zobrazený v prílohe, kde obr. 1 zobrazuje v půdoryse zmointovanú spojku, oibr. 2 je rezom rovinnou I—I obr. 1, obr. 3 je rezom rovinnou II—II obr. 1 obr. 4 zobrazuje v půdoryse veko spojky so zobrazením tvaru prelisu, ktorého vrchol prebieha po budúcej opornej kružnici, ako i tvar a vystuženie pátiek, obr. 5 zobrazuje v řeze detail prelisu po střihu a ohybe dokalibrované oporné hrany veka a oporného krúžku. Z detailu je zřejmý spůsob dosiahnutia vnútorného přesahu oporných hrán veka a oporného krúžku oproti opornej kružnici, obr. 6 je rezom rovinnou III—III obr. 4.The disc clutch and the method for forming it according to the invention is shown in the appendix, where Fig. 1 shows a plan view of a zmointed clutch, oibr. Fig. 2 is a sectional plan view of Fig. 1, Fig. 3 is a plan view of Fig. 1 Fig. 4 shows a plan view of a clutch cover showing the shape of an overhang, the apex of which runs along the future support circle as well as the shape and reinforcement of the frets. Fig. 5 shows a cross-sectional view of a cross-section after shearing and bending of the calibrated support edge of the lid and support ring. In detail, the manner in which the inner overhang of the supporting edges of the lid and the support ring is opposite to the support circle is evident; FIG. 6 is a sectional plane III-III of FIG.

Membránová pružina 1 je ustavená medzi oporné hrany 9 oporného· krúžku 2 a oporné hrany 6 veka 3 spojky, pričom veko 3 spojky a oporný krúžok 2 sú oproti sebe usporiadané tak, aby otvory 15 veka 3 spojky a otvory 16 oporného krúžku 2 sa vzájomne překrývali a prechádzal nimi distančný svorník 19.The diaphragm spring 1 is positioned between the support edges 9 of the support ring 2 and the support edges 6 of the clutch cover 3, wherein the clutch cover 3 and the support ring 2 are arranged opposite each other such that the openings 15 of the clutch cover 3 and the openings 16 of the support ring 2 overlap each other and a stud bolt 19 passed through them.

Veko 3 spojky je tvarované v lisovacom nástroji, čím sa vytvoří prelis 7 přerušený nástrihom 8 u výstužných prelisov 5 budúcich pátiek 4. Prelis 7 sa vo svojom vrchole 14 na opornej kružnici D stříhacím nástrojom rozstrihne, čím sa súčasne vytvoria pátky 4 na veku 3 spojky, ako i budúce oporné hrany 6 na veku 3 spojky a budúce oporné hrany 9 na opornom krúžku 2. Oporné hrany 6 a 9 sa v kalibrovacom nástroji dokalibrujú na veku 3 spojky do opornej hrany 10 a na opornom krúžku 2 do opornej hrany 12, čím sa dosiahne potřebný přesah Dl na veku 3 spojky a přesah D2 na opornom krúžku 2 proti opornej kružnici D pre obojstranné podopretie membránovej pružiny 1.The clutch cap 3 is molded in a press tool to form an overhang 7 interrupted by a notch 8 at the stiffening overhangs 5 of the next skirts 4. The overhang 7 is cut at its apex 14 on the support circle D, thereby forming the skirts 4 on the clutch lid 3 as well as future support edges 6 on the clutch cover 3 and future support edges 9 on the support ring 2. The support edges 6 and 9 are calibrated in the calibrating tool on the clutch cover 3 to the support edge 10 and on the support ring 2 to the support edge 12, whereby the required overlap D1 is reached on the clutch cover 3 and the overhang D2 is supported on the support ring 2 against the support circle D for the double-sided support of the diaphragm spring 1.
