Hydraulinen moottoriHydraulic motor

Keksinnön kohteena on hydraulinen moottori, jonka toisiinsa nähden pyörivässä kotelossa ja akselirakentees-5 sa on yhteisvaikuttavat jarrulamellit, ja jonka akseliin on muodostettu aksiaalinen, painelähteeseen liitettävä poraus, joka, edullisesti lähellä akselin vastakkaista päätä, avautuu akselin pintaan, jolloin porauksen pinta-aukon (aukkojen) yhteyteen on sovitettu sylinterirakenne, 10 joka käsittää akseliin kiinteästi tukeutuvan osan ja liikkuvan, akselin jarrulamelleihin vaikuttavan osan, joka liikkuva osa on jousikuormituksen alainen vastakkaiseen suuntaan mainitun sylinterirakenteen sylinterikammiossa vallitsevaan paineeseen nähden.The invention relates to a hydraulic motor having interlocking brake discs in a rotating housing and an axle structure, and having an axial bore connected to the pressure source, which, preferably near the opposite end of the shaft, opens into the surface of the shaft, whereby the bore surface opening ) is provided with a cylinder structure 10 comprising a part fixed to the shaft and a movable part acting on the brake lamellae of the shaft, which movable part is subjected to a spring load in the opposite direction to the pressure in the cylinder chamber of said cylinder structure.

15 Hydraulimoottorin lamellijarru on yleensä joko jou- sikuormitteinen tai painekuormitteinen. Jousikuormitteisia jarruja varten ja painekuormitteisia jarruja varten on tähän saakka aina tarvittu eri rakenneosat, mistä syystä sekä osien valmistuskustannukset että niiden varastointikus-20 tannukset ovat verraten suuret.15 The disc brake of a hydraulic motor is usually either spring-loaded or pressure-loaded. Until now, different structural components have always been required for spring-loaded brakes and pressure-loaded brakes, which is why both the manufacturing costs of the components and their storage costs are relatively high.

: Tarkoituksena on saada aikaan uusi jarrurakenne, | jonka osat soveltuvat sekä jousikuormitteiseen jarruun et tä painekuormitteiseen jarruun.The aim is to create a new brake structure, whose parts are suitable for both spring-loaded brake and pressure-loaded brake.

Keksinnön mukaisesti saavutetaan tarkoitus alussa 25 mainitun tyyppisessä hydraulisessa moottorissa pääasiallisesti siten, että sylinterirakenteen kiinteänä osana on rengaslevy ja että liikkuva osa käsittää rengaslevyn, jonka kehästä lähtevät, akselin kumpaankin suuntaan, rengas-haarat, joista toinen haara ulottuu tiiviisti kiinteän ren-30 gaslevyn kehän ohitse, jolloin kiinteän rengaslevyn ja liikkuvan osan keskinäinen sijainti akselin suunnassa on vaihdettavissa jousikuormitteista ja vastaavasti painekuor-mitteista jarrurakennetta varten.According to the invention, the object is achieved in a hydraulic motor of the type initially mentioned mainly in that the integral part of the cylindrical structure is an annular plate and the movable part comprises annular branches extending circumferentially in both directions of the shaft. , wherein the relative position of the fixed ring plate and the moving part in the axial direction is interchangeable for spring loads and for pressure-loaded brake structures, respectively.

Patenttivaatimuksissa 2 ja 3 on yksityiskohtaisem-35 min määritelty keksinnön edullisia toteutusmuotoja.Preferred embodiments of the invention are defined in more detail in claims 2 and 3.

2 727822,72782

Seuraavassa selitetään keksintöä viitaten oheiseen piirustukseen.The invention will now be described with reference to the accompanying drawing.

Kuvio 1 esittää pitkittäisleikkausta hydraulisesta moottorista.Figure 1 shows a longitudinal section of a hydraulic motor.

5 Kuvio 2 esittää keksinnön sovellutusta jousikuor- mitteiseen lamellijarruun.Figure 2 shows an application of the invention to a spring-loaded disc brake.

Kuvio 3 esittää keksinnön sovellutusta painekuor-mitteiseen lamellijarruun.Figure 3 shows an application of the invention to a pressure-loaded lamella brake.

Kuviossa 1 ylempi puolisko esittää jousikuormit-10 teista jarrua ja alempi puolisko painekuormitteista jarrua. Keksintö lienee helpommin ymmärrettävissä kuvioiden 2 ja 3 perusteella, seuraavassa viitataan ensisijaisesti näihin.In Fig. 1, the upper half shows the spring-loaded brake and the lower half the pressure-loaded brake. The invention will probably be more easily understood on the basis of Figures 2 and 3, these will be referred to primarily in the following.

Piirustuksen esimerkissä moottorin kotelo 1 pyörii 15 kiinteän akselin 2 ympäri. Koteloon 1 ja akseliin 2 on asennettu jarrulamelleja 3 ja vastaavasti 4, jotka puris-tuessaan toisiaan vasten jarruttavat moottoria. Viitenumero 5 osoittaa akseliporausta, joka on liitettävissä paine-lähteeseen ja joka lähellä akselin vastakkaista päätä 2a 20 haarautuu, viitenumerot 6 ja 7, akselin pintaan. Näiden aukkojen yhteyteen on muodostettu akselin ympäri ulottuva sylinterirakenne, joka käsittää kiinteän rengaslevyn 9 ja liikkuvan osan 10, jossa on rengaslevy 11 ja kaksi sen kehästä lähtevää rengashaaraa 12 ja 13. Toinen, rengaslevyn 25 9 puoleinen haara 12 on edullisesti pitempi kuin vastak kaissuuntainen haara 13, ja pitempi haara 12 ulottuu tiiviisti rengaslevyn 9 kehän ohitse. Akselin päähän 2a on asennettu kiinteä tuki 14, esimerkiksi mutteri.In the example of the drawing, the motor housing 1 rotates 15 around a fixed shaft 2. Brake discs 3 and 4, respectively, are mounted on the housing 1 and on the shaft 2, which, when pressed against each other, brake the motor. Reference numeral 5 denotes a shaft bore which can be connected to a pressure source and which, near the opposite end 2a of the shaft, branches, reference numerals 6 and 7, to the surface of the shaft. A cylindrical structure extending about an axis is formed in connection with these openings, comprising a fixed annular plate 9 and a movable part 10 with an annular plate 11 and two annular branches 12 and 13 emanating from its circumference. The second branch 12 on the annular plate 25 , and the longer leg 12 extends tightly past the circumference of the annular plate 9. A fixed support 14, for example a nut, is mounted on the shaft end 2a.

Kun kyseessä on jousikuormitteinen jarru, asenne-30 taan osat 9 ja 10 kuvion 2 mukaisesti. Rengaslevy 9 tukeutuu akseliolakkeeseen ja liikkuva osa 10 on akselipäähän 2a päin. Liikkuvan osan 10 rengashaara 12 vaikuttaa akselin lamelleihin 4 ja toinen, lyhyempi haara 13 toimii lau-tasjousien 16 tms. vasteena, jotka jouset 16 toisaalta tu-35 keutuvat mutterin 14 kantaan 15. Kun kammiossa 8 vallit- 3 72782 see alhainen paine, painavat jouset 16 liikkuvaa osaa 10 vasemmalle ja jarrulamellit 3 ja 4 puristuvat yhteen. Kammiossa 8 vallitseva paine taas pyrkii siirtämään osaa 10 oikealle ja kun paine on tarpeeksi suuri, antavat jouset 5 16 myöten ja kotelo 1 voi vapaasti pyöriä.In the case of a spring-loaded brake, parts 9 and 10 are mounted as shown in Figure 2. The ring plate 9 rests on the shaft shoulder and the movable part 10 faces the shaft end 2a. The annular branch 12 of the moving part 10 acts on the lamellae 4 of the shaft and the second, shorter branch 13 acts as a response to disc springs 16 or the like, which springs 16 on the other hand support the base 15 of the nut 14. When the low pressure in chamber 8 16 moving parts 10 to the left and the brake discs 3 and 4 are compressed together. The pressure prevailing in the chamber 8, on the other hand, tends to move the part 10 to the right and when the pressure is high enough, the springs 5 give way 16 and the housing 1 can rotate freely.

Kuvio 3 esittää painekuormitteista vaihtoehtoa. Rengaslevy 9 tukeutuu tällöin mutterin 14 päähän ja liikkuvan osan lyhyempi rengashaara 13 vaikuttaa akselin jar-rulamelleihin 4. Kuvion 3 esittämässä tilanteessa poraus 10 5 on paineeton, jolloin jouset 17 ovat siirtäneet liikku van kappaleen 10 vasten rengaslevyä 9 ja kotelo voi vapaasti pyöriä. Porauksen 5 kautta tuleva paineneste puolestaan tunkeutuu rengaslevyn 9 ja liikkuvan osan rengas-levyn 11 väliin laajentaen kammiota 8 ja siirtäen siten 15 liikkuvaa osaa 10 kuviossa vasemmalle, jolloin jarrulamellit 3 ja 4 puristuvat yhteen.Figure 3 shows a pressure-loaded alternative. The annular plate 9 then rests on the end of the nut 14 and the shorter annular branch 13 of the moving part acts on the shaft jar rollers 4. In the situation shown in Fig. 3, the bore 10 5 is depressurized. The pressure fluid coming through the bore 5, in turn, penetrates between the annular plate 9 and the annular plate 11 of the moving part, expanding the chamber 8 and thus moving the movable part 10 in the figure to the left, whereby the brake discs 3 and 4 are compressed.

Osat 9 ja 10 ovat samat kuvioissa 2 ja 3. Sen lisäksi, että samoja osia voidaan käyttää sekä jousikuormit-teisessa jarrussa että painekuormitteisessa jarrussa, pii-20 rustuksen esimerkkiratkaisu on asennus- ja huoltoteknises-ti edullinen, akselinpään 2a viereinen päätykansi tai vaihtoehtoisesti kuvioissa 2 ja 3 näkyvä osa moottorin kotelosta on verraten helposti irrotettavissa eikä moottoria varsinaisesti tarvitse purkaa. Yksityiskohtien osalta osat 9 25 ja 10 voivat luonnollisesti poiketa kuvioiden 2 ja 3 muodoista, kuten myös käy ilmi kuviosta 1.Parts 9 and 10 are the same in Figures 2 and 3. In addition to the fact that the same parts can be used in both spring-loaded and pressure-loaded brakes, an exemplary silicon-20 suspension solution is technically advantageous in terms of installation and maintenance, shaft end 2a or alternatively in Figures 2. and 3 the visible part of the motor housing is relatively easily removable and the motor does not actually need to be dismantled. In detail, the parts 9 25 and 10 may, of course, deviate from the shapes of Figures 2 and 3, as also shown in Figure 1.
