Abstract

An automotive gear box filter consists of a disc-shaped element (13) fixed to a shaft (8) rotating within a housing (1). The disc has an annular chamber (14) holding an annular filter (19). The chamber has a cylindrical outer wall (15) with perforations (16) for oil pressed by centripetal force and emerging from the filter.

Description

20 to Ur u: (J: C.) “<1 (rt OJ O \ Differentialhuset är utforrnat med axeltappar 8, 9, som är lagrade i rullager 10, 11 i huset 1. 20 to Ur u: (J: C.) “<1 (rt OJ O \ The differential housing is formed with shaft pins 8, 9, which are mounted in roller bearings 10, 11 in the housing 1.

På den ena axeltappen 8 är en generellt med 12 betecknad filteranordning fixerad, vilken innefattar en ihålig skivformig del 13, vilken övergår i en ringformig kam- mare 14, som har en cylindrisk yttervägg 15, vilken är koncentrisk med axeltappen 8 och har genomgående, jämnt fördelade perforeringar 16 över hela sin omkrets. Delen 13 har en radiell vägg 17, som är utformad med jämnt fördelade öppningar 18. Inuti kammaren 14 är en ringforrnig filterkropp 19 fixerad. Filterkroppen 19 består av ett grovfilter 19a och ett finfilter 19b, som kan vara uppbyggda av ett flertal grov- resp fmmaskiga metallnätskikt, av vilka det radiellt yttersta anligger mot insidan av den cylindriska väggen 15.Fixed on one shaft pin 8 is an alteration device generally designated 12, which comprises a hollow disc-shaped part 13, which merges into an annular chamber 14, which has a cylindrical outer wall 15, which is concentric with the shaft pin 8 and has a continuous, even distributed perforations 16 over its entire circumference. The part 13 has a radial wall 17, which is formed with evenly distributed openings 18. Inside the chamber 14, an annular filter body 19 is axed. The filter body 19 consists of a coarse filter 19a and a fine filter 19b, which may be built up of a number of coarse or five-mesh metal mesh layers, the radially outermost of which abuts the inside of the cylindrical wall 15.

Det finns flera skäl till att placera den beskrivna filteranordningen 12 i anslutning till differentialhuset 6. Dels medger placeringen maximal diameter hos filteranordningen, vilket ger hög centrifugalkraft på oljan i kammaren 14 samtidigt som man säker- ställer att en stor del av den skivformiga delen 3 och kammaren 14 kommer att vara nedsänkt under ytan på oljan i huset i vilotillstånd, och dels undviks ökning av rote- rande massor, som skall synkroniseras.There are several reasons for placing the described ordningenlter device 12 adjacent to the differential housing 6. On the one hand, the location allows maximum diameter of the ,lter device, which gives high centrifugal force on the oil in the chamber 14 while ensuring that a large part of the disc-shaped part 3 and the chamber 14 will be immersed below the surface of the oil in the housing in the rest state, and on the other hand the increase of rotating masses, which are to be synchronized, is avoided.

Varje gång bilen stoppas strömmar olja genom hålen 18 in i den under oljeytan befintliga delen av filteranordningen. När bilen startar och differentialhuset 6 roterar så roterar även filteranordningen 12, varvid det av centrifugalkraften alstrade olje- trycket i kammaren 14 pressar olja genom filterkroppen 19 och ut genom perfore- ringarna 16. Fasta partiklar kommer härvid att fastna i filterkroppen 19. En mindre mängd olja kan även under drift stänka in i kammaren 14 genom öppningama 18, men den fyllning som åstadkommes vid varje driftstopp är dominerande för filtre- ringseffekten.Each time the car is stopped, oil flows through the holes 18 into the part of the filter device located below the oil surface. When the car starts and the differential housing 6 rotates, the filter device 12 also rotates, whereby the oil pressure generated by the centrifugal force in the chamber 14 presses oil through the filter body 19 and out through the perforations 16. Solid particles will thereby get stuck in the filter body 19. A small amount oil can also splash into the chamber 14 through the openings 18 during operation, but the filling produced at each downtime is dominant for the filtration effect.

Un ( J' C '\ \l (TI C '\l (_;\ Med hjälp av den beskrivna filteranordningen kan till mycket låg kostnad och med försumbar effektförlust effektiv utfiltrering av mycket små partiklar uppnås. Till den låga kostnaden bidrar bl a att den skivforrniga delen 13 och kammaren 14 kan gjutas i ett stycke av ett låghållfast material, t ex plast, eftersom den inte är utsatt för några större påkänningar.Un (J 'C' \ \ l (TI C '\ l (_; \ With the help of the described alteration device, at very low cost and with negligible power loss, efficient alteration of very small particles can be achieved. the disc-shaped part 13 and the chamber 14 can be cast in one piece from a low-strength material, for example plastic, since it is not subjected to any major stresses.
