Now, the progress of automotive materials is closely around the themes of environmental protection, energy saving, safety, comfort and low cost, so the development of automotive materials is more diversified, the most prominent and urgent is lightweight, compared with 10 years ago, the structure of automotive materials has changed significantly. The use of new materials and advanced manufacturing processes are complementary, and the automotive industry is working hard to develop new manufacturing processes in posodobite tradicionalne panoge . Poleg tradicionalnih aluminijevih in magnezijevih materialov so titanijevi in kompozitni materiali tudi lahki materiali z odlično zmogljivostjo, vendar je trenutna cena še vedno višja, vendar bo z napredkom tehnologije in povečanjem porabe cena počasi upadla .
Titanium's excellent performance such as light weight and high strength has long been favored by manufacturers, and the application of titanium in racing cars has a history of nearly 40 years. The U.S. has produced titanium intake valves, exhaust valves, valve retainers and stems for racing cars.
1. Motor Connecting Rod
When the car is driving at full speed, most of the frictional losses of the engine are caused by the piston connecting rod components (pistons, piston pins and connecting rods), and when the mass is reduced, the fuel utilization rate is greatly improved, and the exhaust volume is also reduced accordingly. By using titanium to manufacture this part, the engine drive temperature has risen and the temperature used is higher than that of the Prejšnji del aluminijeve zlitine . povezovalne palice bi morale imeti visoko trdnost, odpornost na utrujenost, togost in odpornost proti obrabi, zato so titanove zlitine in kompozitni materiali postali primerni materiali za proizvodnjo, ki povezujejo palice, in zatiči bata in bata so bili lahki, tako da so bili lahki {2 {2 {2 {2 {2 {2 veliki vibraciji, ki sta bili zelo zmanjšani, da so bili v velikem zmanjšanju motorja {2 {2 {2 {2 {2 {2 {2 {2 {2 {2 {2 {2 {2 { Ima visoke zahteve za trdnost, odpornost na obrabo, togost, toplotno odpornost itd. ., izbrati je treba zlitine iz titanijeve, ki vsebujejo več titanij-aluminijevih spojin . hitrost motorja se iz dneva v dan povečuje in najbolje je, da se titanijeva zlitina za ventile, itd. upor .
2. sesalni ventil z nižjo temperaturo .
Leta 1956 je Volkswagen zgradil majhen avtomobil, za katerega se je govorilo, da se uporablja za razstave, njegovo telo pa je bilo izdelano iz vsega titanija . Naslednji model COO je bil opremljen s 300 ml cilinderskim motorjem z neto težo le 290 kg, narejen iz lahkih materialov, kot so AL, in TI rese, in TI rese, in TI rese, in TI rese, in TI rese, in TI rese, in TI rese, in TI rese, in TI, in TI rese, in TI, in TI rezin, in TI, in TI rese, in TI, in TI rese, in TI, in TI rese in TI, in TI, in TI, in TI, in TI, in TI, in TI, in TI, in TI, in TI Resin, in TI Resin Matrix km/l . Leta 1990 je bila povezovalna palica NSX V -6 dirkalni avtomobil Honda Motor Company Japonske, narejena iz ti -3 al -2.5 zlitine, zlitina, ki jo je mogoče razrezati z visokimi hitrostmi, v primerjavi 24- ventil V -6 motor dirkalnega avtomobila NSX, ki ga je proizvajalo podjetje 3 . 9 sekund. Povezavne palice Porschejevih avtomobilov so tudi iz titana.
The valve seat is made of titanium alloy, widely used in racing cars, mostly made of Ti-6Al-4V alloy, and also made of Ti-5Al-2Cr-1Fe alloy, the shape of the valve seat is simple, easy to machine, the cost is also low, and there is no need for special surface Zdravljenje in njegova kakovost je 10 g ~ 12 g lažja od kakovosti . japonske avtomobilske tovarne, ki so bile uporabljene ti -5 al -2 cr -1 zlitine, da naredijo ročice in nekatere druge dele, in ti {11} {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12 {12. Spodnji vijaki palice . Po Japonski izkušnji se za avtomobilske napajalne ventile uporablja 0 . 8 kg ~ 0,9 kg titana, kar je enakovredno zmanjšanju teže 20 kg.
3. izpušna cev in dušilec
Količina titana, ki se uporablja v avtomobilskih izpušnih ceveh, je velika . v preteklosti, izpušne cevi in mufflerji so bili večinoma izdelani iz navadne jeklene, aluminijeve zlitine in vlaken, ki je bila usmerjena jeklo . Proizvodnja izpušnih cevi in dušilcev dušilcev mora skozi različne procese oblikovanja, kot sta upogibanje in hladno stiskanje, in materiali morajo imeti dobro hladno delovno oblikovanje lastnosti . Poleg
Poleg zahtev toplotne odpornosti, odpornosti proti obrabi, ampak tudi ne vsebujejo svinca in kobalta, ameriška avtomobilska podjetja večinoma uporabljajo titanovo zlitino za izdelavo vnosa in izpušnih ventilov, sesalni ventil je TC4, izpušni ventil alloy. For Japanese automobile companies, the valve seats of racing cars are generally made of TC4 alloy, and some are made of Ti-5Al-2Cr-1Fe alloy. The exhaust pipe is made of titanium alloy tail nozzle/return pipe components, which are not corroded by Kloridne soli in izpušni plini, ki vsebujejo žveplo, celo zvari, in so 8 . 2 kg lažji od tradicionalnih izpušnih sistemov iz nerjavečega jekla, izboljšanje učinkovitosti goriva, pospeševanje in skrajšanje zavornih razdalj.
Masa dušilnika titanijeve zlitine je le 5 kg ~ 6 kg, kar je veliko lažje od tiste, ki je narejena iz nerjavečega jekla, in skoraj vsi dušilci japonskih avtomobilov so bili zlitini s titanom . titanijevega mufflerja in sistema iz tarčkov, ki so le 11 {6} leži kot 20kg nerjavečega jekla, vendar nekoliko močnejši . ti -33.5 al -1 nb -0.5 cr -0.5 silitih, ki jih je razvila aporacija Daido Iron and Steel, v primerjavi z dobrim maru, ki je dobro proizvodni material izpušnih motorjev, je dobro proizvodni material izpušnih motorjev izpušnih ventil. Toplotno odporna jeklena in nikljeva zlitina, ki se uporablja v izpušnem ventilu, izjemne značilnosti titanove zlitine: majhna gostota, dobra toplotna odpornost in večja zmogljivost trdnosti nad 540 stopinj, odpornost na lezenje pa je višja kot pri niklovski zlitini, pa tudi dobra odpornost na obrabo.
The actual use proves that the service life of the titanium alloy exhaust system is the same as the life of the car, which is 12 a~14 a, and the service life of the stainless steel device is only 8 a, so it is more cost-effective to consider the use of titanium from this point. The mass of titanium alloy mufflers is generally < 12 g, which is more than 40% lighter than stainless steel, which helps to improve the performance avtomobila in življenjska doba dušiča je polmarna . zlitine titanijeve in titanijeve zlitine so popolnoma inertne, lahko v celoti reciklirate brez znižanja papirja in med proizvodnim postopkom ne uvajate nobenih škodljivih stranskih produktov .
Obroči za sedež ventila imajo široko paleto aplikacij v dirkalnih avtomobilih in športnih avtomobilih, svetovna proizvodnja pa naj bi presegla 600, 000 kosov v letu 2020, običajno iz zlitine TC4, lahko izdelamo z metodo mehanskega rezanja, stroški obdelave niso visoki, in japonske korporacije ni treba, mitsubishi korporacije, mitsubishi korporacije, mitsubishi korporacije, pa mitsubishi korporacije, mitsubishi korporacije, mitsubishi korporacije o Ti -5 al -2 cr -1 fera zlitine za izdelavo sedežev ventila .
4. vzmeti
In terms of strength, density and modulus of elasticity, titanium alloy is a good material for making springs, and TC4 alloy was used to make springs for Porsche 917 racing cars nearly 20 years ago. Ford Motor Company replaced the steel spiral suspension springs of the past with RMI alloy springs in race cars, reducing the weight by 53 percent, but the high production cost limited its wide application. Later, the titanium metal company (Timet) developed a new type of Ti-4.5Fe-6.8Mo-1.5Al alloy based on Fe and Mo, called low-cost titanium alloy LCB (Low Cost Beta), which not only maintains the advantages of c alloy, but also has a reasonable price, which is used to manufacture springs, which can be processed with the original steel spring production equipment, supported by Volkswagen, and the springs manufactured are 1/3 lighter than those of steel, and the price of titanium alloys has decreased by 50%. What's more, the height of titanium alloy springs is 50%~80% shorter than that of steel springs, which means that you can get more riding and cargo space.
Izvidne izlivne izlitine imajo tudi vidnejšo prednost - visoko korozijsko odpornost, v standardnem testu utrujenosti soline korozije se utrujenost jeklenih vzmeti zmanjša za 50% v primerjavi z zrakom, medtem ko se vzmeti iz titanijeve zlitine zmanjšajo le za 4%, poleg tega pa se titanijeve zlitine ni treba zdraviti z zaščitno površino.
5. pritrdilni elementi in zavore
Because of its high corrosion resistance, light weight and small thermal expansion coefficient, titanium alloy fasteners have been widely used in aerospace manufacturing, and if its production cost has decreased greatly, it will also become a common fastener for cars. The thermal conductivity and wear resistance of titanium are low, and can not be applied to brake impellers, but because of its excellent corrosion resistance, it je bil uporabljen za pripravo tesnilnega obroča in vodilnega zavornega zavornega zatiča prirobnice priključne priključke zavorne kravate, zaradi majhne toplotne prevodnosti pa ima tudi določen zaščitni učinek na zavorno tekočino .
