The turbo compressor housing for motor vehicles according to the invention consists of at least two parts (1, 2) produced according to processing requirements of plastic materials, which when assembled and provided with a non-detachable link result in the turbo compressor housing (9). The manufacturing procedure of the turbo compressor housing for motor vehicles consists of the following steps: in the first step at least two parts (1, 2) are made individually in specially designed tools/moulds for processing plastic materials. In the second step these two components (1, 2) or these components (1, 2, 3) are assembled so that they form an housing (9). In the third step these two components (1, 2) or these components (1, 2, 3) are linked together, particularly by welding into a non-detachable assembly.

Description

Ohišje turbokompresorja pri motornih vozilih in postopek izdelave le-tegaTurbocharger housing for motor vehicles and process for its manufacture

Izum se nanaša na ohišje turbokompresorja pri motornih vozilih in postopek njegove izdelave. Turbokompresor sam je namenjen za vpihavanje zraka v zgorevalni/kompresijski prostor motorja z notranjim izgorevanjem. Ohišje turbokompresorja je razmeroma zapleten izdelek, ki v osnovi obsega osrednje razporejen, v aksialni smeri potekajoč prehod, katerega prečni presek je v splošnem spremenljiv, obenem pa tudi v cirkularni smeri potekajoč prehod (difuzor), katerega prečni presek je prav tako spremenljiv.The invention relates to a turbocharger housing for motor vehicles and a process for its manufacture. The turbocharger itself is designed to blow air into the combustion / compression space of an internal combustion engine. The turbocharger housing is a relatively complex product, which basically comprises a centrally arranged axially flowing passage whose cross-section is generally variable and at the same time a circular flow (diffuser) whose cross-section is also variable.

**

Izum temelji na problemu, kako zasnovati ohišje turbokompresorja, katerega teža bo manjša, obenem pa ga bo možno izdelati enostavneje, bolj ekonomično in tudi na ekološko bolj sprejemljiv način kot doslej znana ohišja.The invention is based on the problem of how to design a turbocharger housing whose weight will be less, but at the same time it will be possible to make it simpler, more economical and also in an ecologically more acceptable way than previously known housings.

Ohišja turbokompresorjev so doslej izdelovali z litjem, zlasti z litjem aluminija oz. aluminijevih zlitin v ustrezne kalupe oz. kokile. Tako dobljene odlitke je bilo potrebno čistiti, preizkušati glede na tesnost, zatem pa še mehansko obdelati. Kadar gre za zahtevnejše konstrukcije ohišij, ki so npr. opremljena z različnimi priključki, je uporaba takoimenovanih peščenih jeder neizogibna. Pod izrazom peščeno jedro razumemo v posebnem orodju vnaprej pripravljeno jedro, ki je pred litjem vstavljivo v kalup oz. kokilo, zaradi česar odlitek na določeni lokaciji obsega votlino oz. vdolbino. Peščena jedra kot vezivo vsebujejo fenole (smole), ki ob stiku z vročo talino sproščajo strupene snovi. Splošno znano je, da je način proizvodnje povezan z visokimi stroški in izjemno zahtevnimi ukrepi v smislu varovanja okolja. Tovrstne rešitve so opisane v CH 335 298 A, US 5,961,281 ter v DE 197 44 33 Al.So far, the turbocharger housings have been manufactured by casting, especially by casting aluminum or. aluminum alloys in suitable molds or. chicken. The casts thus obtained had to be cleaned, tested for tightness, and then mechanically treated. When it comes to more complex housing designs, e.g. equipped with different attachments, the use of so-called sand cores is inevitable. The term sand core is understood to mean, in a special tool, a pre-prepared core, which can be inserted into the mold or mold before casting. the mold, which causes the cast at a particular location to comprise a cavity. indentation. Sandy cores, as a binder, contain phenols (resins) which, on contact with hot melt, release toxic substances. It is common knowledge that the mode of production is associated with high costs and extremely demanding measures in terms of environmental protection. Such solutions are described in CH 335 298 A, US 5,961,281, and in DE 197 44 33 Al.

Po izumu je ohišje turbokompresorja v splošne m izvedeno iz vsaj dveh ali več delov, ki sestojijo iz umetne mase in od katerih je vsak zase proizveden v posebnem orodju ter zatem z vsakokrat pripadajočim(i) delom/deli nerazstavljivo povezan, zlasti zvarjen v vsakokrat želeno ohišje turbokompresorja. Pri tem je vsak od omenjenih delov tako zasnovan, da po eni strani ustreza zakonitostim predelave plastičnih mas, po drugi strani pa je prilagojen preostalim delom, s katerimi skupaj tvori ohišje po izumu. Ohišje turbokompresorja motornega vozila, ki obsega vsaj en v svoji aksialni smeri potekajoč prehod spremenljivega prečnega prereza in vsaj en v svoji cirkulami smeri potekajoč prehod spremenljivega prečnega prereza, po potrebi pa tudi na ustrezen način razporejene priključke in vrtine, po izumu sestoji iz vsaj dveh posebej, v skladu z zakonitostmi predelave plastičnih mas proizvedenih delov, ki v medsebojno sestavljenem stanju ob sočasni zagotovitvi njune nerazstavljive medsebojne povezave tvorita ohišje turbokompresorja. V prednostne primeru izvedbe ohišje turbokompresorja sestoji iz vsaj treh ločeno proizvedenih delov, ki sestojijo iz plastične mase in ki v medsebojno sestavljenem stanju ter ob sočasni zagotovitvi njihove nerazstavljive medsebojne povezave tvorjo ohišje turbokompresorja. Pri tem vsak izmed prej omenjenih dveh ali treh sestavnih delov sestoji iz polifenilensulfida (polyphenylen-sulphida), ki so prednostno med seboj nerazstavljivo povezani z varjenjem, in sicer z indukcijskim varjenjem in/ali z ultrazvočnim varjenjem in/ali z vibracijskim varjenjem.According to the invention, the turbocharger housing in general m is made of at least two or more parts consisting of plastic and each of which is produced in a special tool and subsequently individually connected to the respective part (s), especially welded to each desired turbocharger housing. In this case, each of the aforementioned parts is designed to meet, on the one hand, the laws of plastic processing, and on the other, it is adapted to the rest of the parts which together form the housing of the invention. A motor vehicle turbocharger housing comprising at least one variable cross section in its axial direction and at least one variable cross section in its circular direction and, if necessary, also appropriately arranged connections and bores, according to the invention consists of at least two separately , in accordance with the laws of plastic processing of the manufactured parts, which in an interconnected state, while ensuring their indivisible interconnections, form a turbocharger housing. In a preferred embodiment, the turbocharger housing consists of at least three separately manufactured plastic-consisting parts which, in an interconnected state, while ensuring their indivisible interconnection, form the turbocharger housing. Each of the aforementioned two or three components consists of polyphenylenesulfide (polyphenylenesulfide), which are preferably indissolubly linked to welding, namely induction welding and / or ultrasonic welding and / or vibration welding.

Izum obsega tudi postopek izdelave ohišja, v katerem se v prvem koraku ločeno, upoštevajoč zakonitosti predelave umetnih mas, izdela potrebno število sestavnih delov, nakar se v drugem koraku te sestavne dele sestavi, tako da skupaj tvorijo ohišje turbokompresorja, zatem pa se v tretjem koraku te sestavne dele med seboj poveže v nerazstavljivo povezavo, pri čemer se jih prednostno medsebojno zvari, zlasti npr. s pomočjo ultrazvočnega ali indukcijskega ali vibracijskega varjenja. Postopek izdelave ohišja turbokompresorja motornega vozila je po izumu značilen po tem, da se v prvem koraku vsakega zase in v posebej prirejenih orodjih/kalupih za predelavo plastičnih mas v skladu z zakonitostmi predelave plastičnih mas izdela vsaj dva sestavna dela, nakar se v drugem koraku ta sestavna dela oz. te sestavne dele medsebojno sestavi, tako da tvorijo ohišje, zatem, pa se v tretjem koraku ta sestavna deta oz. te sestavne dele medsebojno poveže v nerazstavljivo zvezo. Pri prednostni izvedbi postopka se v prvem koraku vsakega zase in v posebej prirejenih orodjih/kalupih za predelavo plastičnih mas v skladu z zakonitostmi predelave plastičnih mas izdela vsaj dva sestavna dela, prednostno pa vsaj tri sestavne dele, sestoječe iz polifenilensulfida (polyphenylen-sulphida), nakar se v drugem koraku ta sestavna dela oz. te sestavne dele medsebojno sestavi, tako da tvorijo ohišje, zatem pa se v tretjem koraku ta sestavna dela oz. te sestavne dele medsebojno poveže v nerazstavljivo zvezo. Še bolj prednostna izvedba postopka po izumu predvideva, da se v prvem koraku vsakega zase in v posebej prirejenih orodjih/kalupih za predelavo plastičnih mas v skladu z zakonitostmi predelave plastičnih mas izdela vsaj dva sestavna dela, prednostno pa vsaj tri sestavne dele, sestoječe iz polifenilensulfida (polyphenylen-sulphida), da se v drugem koraku ta sestavna dela oz. te sestavne dele medsebojno sestavi, tako da tvorijo ohišje, nakar se v tretjem koraku ta sestavna dela oz. te sestavne dele z indukcijskim varjenjem in/ali z ultrazvočnim varjenjem in/ali z vibracijskim varjenjem medsebojno poveže v nerazstavljivo zvezo.The invention also includes a method of manufacturing a housing in which, in the first step, the necessary number of components is produced separately, taking into account the regularities of the processing of plastics, and then in the second step these components are assembled to form the turbocharger housing together, and then in the third step. these components are interconnected in an indivisible connection, preferably welded to one another, in particular e.g. by means of ultrasonic or induction or vibration welding. The process of manufacturing a motor vehicle turbocharger housing according to the invention is characterized in that in the first step, at least two components are produced in the first step of each of them and in specially adapted plastics tools / molds according to the laws of plastic processing, and then in the second step components or these components are interconnected to form a housing, and then, in the third step, this component detects, respectively. it connects these components to an indivisible union. In the preferred embodiment of the process, at least two components and preferably at least three components consisting of polyphenylenesulfide (polyphenylenesulfide) are produced in the first step of each of them and in specially adapted plastic processing tools / molds in accordance with the laws of plastic processing. then in the second step these components or these components are interconnected to form a housing, and then in the third step, these components, respectively. it connects these components to an indivisible union. An even more preferred embodiment of the process of the invention provides that at least two components and preferably at least three components consisting of polyphenylsulfide are produced in the first step of each of them and in specially adapted plastic processing tools / molds in accordance with the laws of plastic processing (polyphenylen-sulphida), in the second step these components or these components are interconnected to form a housing, and in the third step, these components or components are assembled. these components are interconnected by induction welding and / or ultrasonic welding and / or vibration welding.

Najbolj prednostno gradivo, iz katerega je izvedeno ohišje, t.j. iz katerega sestojijo omenjeni sestavni deli ohišja, je polifenilensulfid (polyphenylen sulphid), ki je tudi pri razmeroma visokih temperaturah (npr. približno 240°C) zmožen kljubovati razmeroma visokim mehanskim obremenitvam.The most preferred material from which the housing is derived, i.e. of which said housing components are composed, polyphenylenesulfide (polyphenylen sulphide) is capable of withstanding relatively high mechanical loads even at relatively high temperatures (eg about 240 ° C).

Primer izvedbe ohišja turbokompresorja je prikazan na priloženi skici, pri čemer kaže Sl. 1 ohišje turbokompresorja po izumu.An exemplary embodiment of a turbocharger housing is shown in the accompanying drawing, with FIG. 1 is a turbocharger housing according to the invention.

Sl. 2 pa sestavne dele ohišja pred izdelavo ohišja.FIG. 2 shows the components of the housing before the housing is manufactured.

Ohišje 9 turbokompresorja, ki je prikazano na sl. 1, je razmeroma zapleten izdelek, ki obsega v aksialni smeri potekajoč prehod 91 ter v cirkulami smeri potekajoč prehod 92. Prečna prereza omenjenih prehodov 91, 92 sta v njuni vzdolžni smeri v splošnem spremenljiva. Razen tega je ohišje 9 v splošnem oz. po potrebi zasnovano z različnimi priključki 93 in vrtinami 94, razporejenimi na vsakokrat izbranih lokacijah.The turbocharger housing 9 shown in FIG. 1 is a relatively complex product, comprising in the axial direction a passing passage 91 and in circular directions a passing passage 92. The cross-sections of said passages 91, 92 are generally variable in their longitudinal direction. In addition, the housing 9 is generally or. if necessary, designed with various connectors 93 and boreholes 94 arranged at each location selected.

Kot je razvidno na sl. 2, ohišje 9 v osnovi sestoji iz vsaj dveh sestavnih delov 1, 2, pri čemer gre v danem primeru za tri sestavne dele 1, 2, 3. Vsak od omenjenih delov 1, 2, 3 je zasnovan po zakonitostih, ki jih narekuje stroka na področju predelave plastičnih mas. To še zlasti pomeni, da je vsak od sestavljenih delov tako zasnovan, da ga je mogoče izdelati v orodjih za predelavo plastičnih mas ob upoštevanju skrčkov, zakonitosti pri segrevanju in ohlajanju plastične mase, izmetavanju iz orodja in podobnih pogojev. Hkrati so sestavni deli 1, 2, 3 tako zasnovani, da so med seboj sestavljivi in po zagotovitvi njihove nerazstavljive medsebojne povezave tvorijo ohišje 9 turbokompresorja.As can be seen in FIG. 2, the housing 9 consists essentially of at least two components 1, 2, in which case three components 1, 2, 3 are in question. Each of said parts 1, 2, 3 is designed according to the laws dictated by the profession in the field of plastics processing. This means, in particular, that each of the components is designed to be manufactured in plastic processing tools, taking account of shrinkage, regularities in heating and cooling the plastic, ejection from the tool and similar conditions. At the same time, the components 1, 2, 3 are designed to be interconnected and, after ensuring their indivisible interconnections, to form the housing of a 9 turbocharger.

V danem primeru je vsak od omenjenih sestavnih delov 1, 2, 3 izveden iz umetne mase, ki je polifenilensulfid (polyphenylen sulphid), ki je tudi pri razmeroma visokih temperaturah (npr. približno 240°C) zmožen kljubovati razmeroma visokim mehanskim obremenitvam. Izhajajoč iz dejstva, daje ohišje 9 med uporabo izpostavljeno temperaturi največ 180 do 200°C, je takšna izbira gradiva očitno lahko povsem ustrezna. Pri tem je vsak od omenjenih delov 1, 2, 3 proizveden v posebnem orodju/kalupu, katerega življenjska doba znaša približno 500.000 izdelkov, zaradi cesarje strošek izdelave orodja na enoto izdelka (sestavnega dela 1, 2, 3) lahko zelo nizek. Nerazstavljivo povezavo omenjenih delov 1, 2, 3 v tako dobljeno, v bistvu enovito ohišje 9, je mogoče realizirati s pomočjo varjenja, npr. indukcijskega, vibracijskega ali ultrazvočnega varjenja.In each case, each of the aforementioned components 1, 2, 3 is made of plastic, which is polyphenylenesulfide (polyphenylen sulfide), which is capable of withstanding relatively high mechanical loads even at relatively high temperatures (eg about 240 ° C). Given the fact that the housing 9 is exposed to a temperature of 180 to 200 ° C during use, such a choice of material may obviously be perfectly appropriate. Each of the aforementioned parts 1, 2, 3 is produced in a special tool / mold whose lifetime is approximately 500,000 products, which can result in a very low unit cost of producing tools per unit of product (component 1, 2, 3). The indivisible connection of said parts 1, 2, 3 to the thus obtained substantially uniform housing 9 can be realized by welding, e.g. induction, vibration or ultrasonic welding.

Za postopek izdelave ohišja turbokompresorja je značilno, da se v ločenih korakih, v posebnih orodjih za predelavo plastičnih mas in upoštevajoč zakonitosti predelave plastičnih mas, proizvede vsaj dva medsebojno v ohišje 9 sestavljiva dela 1, 2, nakar se ta dela oz. te dele sestavi in medsebojno zvari. Zlasti je prednostno, če se kot gradivo za izdelavo omenjeni delov uporabi polifenilensulfid (polyphenylen sulphid). Razen tega je prednostno, če se medsebojno zvarjenje omenjenih delov izvrši bodisi z ultrazvočnim ali indukcijskim ali vibracijskim varjenjem.The process of manufacturing the turbocharger housing is characterized by the fact that in separate steps, using special plastic processing tools and taking into account the regularity of plastic processing, at least two component parts 1, 2 are produced into the housing 9 after which these parts or parts are manufactured. assembles and welds these parts. It is particularly advantageous to use polyphenylenesulfide (polyphenylen sulfide) as the material for the manufacture of said parts. In addition, it is preferable that the welding of said parts be accomplished by either ultrasonic or induction or vibration welding.

Tako dobljeno ohišje 9 turbokompresorja, je lahko za približno 45% oz. za skoraj polovico lažje od doslej znSnih ohišij iz aluminija ali aluminijevih zlitin. Izdelava razmeroma enostavnih sestavnih delov 1, 2, 3 in zatem njihovo sestavljanje in povezovanje je nedvomno pristop, ki bistveno poenostavi izdelavo ohišij 9, še zlasti v velikoserijski proizvodnji. Za izdelavo ohišja 9 po izumu niso potrebna več nikakršna jedra in nikakršna veziva, zato je proces izdelave za okolje praktično neobremenjujoč.The 9 turbocharger housing thus obtained can be up to about 45% or. almost half the weight of conventional aluminum or aluminum alloy housings. The production of relatively simple components 1, 2, 3 and then their assembly and connection is undoubtedly an approach that significantly simplifies the construction of housings 9, especially in large-scale production. The construction of the housing 9 according to the invention no longer requires any cores and no binders, so the manufacturing process for the environment is virtually unburdening.
