Manuel \u015fanz\u0131manda en az\u0131ndan yanan debriyaj\u0131n kokusu “dur” der. Otomatik \u015fanz\u0131manlar ise (tork konvert\u00f6r\u00fc, CVT ya da robotize) sessizce bozulur ve tamiri \u00e7ok k\u0131ymetlidir.<\/p>\n
NE KADAR GAZ O KADAR G\u00d6M\u00dcLME<\/b><\/p>\n
Gaza y\u00fcklenmemeniz i\u00e7in birinci neden kolay bir fizik kural\u0131 olan ‘s\u00fcrt\u00fcnme’dir. Tekerlekler y\u00fcksek zamanda patinaj yapt\u0131\u011f\u0131nda \u0131s\u0131n\u0131r. Alt\u0131ndaki kar an\u0131nda erir, suya d\u00f6n\u00fc\u015f\u00fcr ve \u00e7abucak akabinde cam \u00fczere bir buz katman\u0131 olu\u015fur.<\/p>\n
Ortaya “cilalama” tesiri \u00e7\u0131kar. Ne kadar \u00e7ok gaz verirseniz, alt\u0131n\u0131zda o kadar derin ve kaygan bir \u00e7ukur a\u00e7ars\u0131n\u0131z. \u00c7ivili lastikler bile bu durumda freze \u00fczere \u00e7al\u0131\u015farak arac\u0131 saniyeler i\u00e7inde tabana g\u00f6mer.<\/p>\n
\u015eANZIMAN BU Y\u00dcZDEN PATLAR<\/b><\/p>\n
En korkutucu senaryo budur. Birden fazla arabada h\u00fcr diferansiyel bulunur. Misyonu, virajlarda tekerleklerin farkl\u0131 s\u00fcratlerde d\u00f6nmesini sa\u011flamakt\u0131r.<\/p>\n
Ara\u00e7 tak\u0131l\u0131p kald\u0131\u011f\u0131nda bir tekerlek \u00e7amura kilitlenir, ba\u015fkas\u0131 ise sizin gaz vermenizle \u00e7\u0131lg\u0131nca d\u00f6nmeye ba\u015flar. Bu s\u0131rada diferansiyel i\u00e7indeki k\u00fc\u00e7\u00fck di\u015fliler (satelitler) \u00e7ok y\u00fck alt\u0131nda kal\u0131r. Ya\u011f an\u0131nda \u00e7ok \u0131s\u0131n\u0131r, satelitler adeta mile kaynar.<\/p>\n
Sonu\u00e7ta ise satelit mili k\u0131r\u0131l\u0131r, \u015fanz\u0131man g\u00f6vdesi delin\u0131r ve arac\u0131n alt\u0131nda bir ya\u011f g\u00f6l\u00fc g\u00f6r\u00fcrs\u00fcn\u00fcz. Bu, tam revizyon ya da kesim de\u011fi\u015fimi demektir.<\/p>\n
M\u0130LLER VE AKSLAR NASIL KIRILIYOR?<\/b><\/p>\n
Bir \u00f6teki tehlike de ani tutunmad\u0131r. Tekerlek havada ya da buzda 60\u201380 km\/s muadili s\u00fcratle d\u00f6nerken bir anda asfalta ya da sert yere temas ederse, d\u00f6nme birdenbire durur.<\/p>\n
Motor ve \u015fanz\u0131man\u0131n ataleti akslara ve \u015faftlara balyoz \u00fczere biner. Bu, giden bisikletin tekerle\u011fine demir \u00e7ubuk sokmak \u00fczeredir. Bir\u00e7ok vakit aks di\u015fleri s\u0131yr\u0131l\u0131r ya da CVT \u015fanz\u0131manlarda kay\u0131\u015f kopar. CVT’ler patinajdan en \u00e7ok korkan \u015fanz\u0131manlard\u0131r; konik y\u00fczeylerde \u00e7izikler an\u0131nda olu\u015fur.<\/p>\n
SESS\u0130Z B\u0130R SU ISITICISI<\/b><\/p>\n
Klasik otomatiklerde debriyaj\u0131n misyonunu tork konvert\u00f6r\u00fc \u00fcstlenir ve g\u00fcc\u00fc ya\u011f (ATF) \u00fczerinden iletir. Ara\u00e7 yerinde dururken siz gaz verdi\u011finizde, motor g\u00fcc\u00fc harekete de\u011fil, ya\u011f\u0131n \u0131s\u0131nmas\u0131na masraf.<\/p>\n
ATF kaynamaya ba\u015flar. S\u00fcrt\u00fcnme balatalar\u0131 yanar ve par\u00e7alan\u0131r. Bu tortular hidrolik beyin kanallar\u0131n\u0131 t\u0131kar. Sonu\u00e7ta bir ay sonra “durduk yere” vites ge\u00e7i\u015flerinde vuruntu ve sars\u0131nt\u0131 ba\u015flar.<\/p>\n

Yumu\u015fak karda kald\u0131ysan\u0131z ESP’yi kapat\u0131n. Aksi halde motoru bo\u011far.<\/p>\n
Bir tekerlek havadaysa ESP\u2019yi a\u00e7\u0131n. Bir\u00e7ok ara\u00e7, frenle diferansiyel kilidi taklidi yaparak g\u00fcc\u00fc yere basan tekerle\u011fe aktar\u0131r.<\/p>\n
Paspas, Kum ve Bas\u0131n\u00e7 Hilesi<\/b><\/p>\n
– Kuma\u015f paspaslar i\u015fe yaramaz; lastik onlar\u0131 yutar. Tekerleklerin alt\u0131na koymak i\u00e7in kau\u00e7uk paspas kullan\u0131n.<\/p>\n
– \u00c7eki\u015f olan tekerleklerin alt\u0131na, derine yerle\u015ftirin.<\/p>\n
– Kedi kumu (odun ya da ta\u015f bazl\u0131) eksiksiz bir alternatiftir; nemi emer, tutunmay\u0131 art\u0131r\u0131r.<\/p>\n
