Abstract

Transmisija vozila jedan je od najvažnijih sustava na cestovnim motornim vozilima. Njezina zadaća je snagu motora transformirati i dovesti do pogonskih kotača. No mjenjač kao dio transmisije ima najveću ulogu u tom procesu. Naime mjenjač mora omogućiti lako pokretanje vozila, ugodnu vožnju, lako zaustavljanje vozila i rad motora u praznom hodu. Automatski mjenjači su u izvedbi ovih radnji uvijek bili pristupačniji vozaču. Kod automatskih mjenjača radnje koje je izvodio vozač bile su svedene na... More minimum, te je vozač mogao posvetiti potpunu pažnju na promet. No nedostaci koje su imali automatski mjenjači činili su ih manje popularnim od ručnih mjenjača. Viša cijena, potrebno dulje vrijeme za promjenu stupnja prijenosa, te slabije izlazne karakteristike motora samo su neke od nedostataka. Pojavom DSG mjenjača koji nastoji uklopiti sve prednosti automatskih i ručnih mjenjača, učinili su automatske mjenjače nešto popularnijima. Zbog svoje konstrukcije koju čine dvije spojke i dva vratila mjenjača, DSG mjenjačima je potrebno vrlo kratko vrijeme za promjenu stupnja prijenosa, kao i korištenje tarnih spojki koje omogućuju maksimalne izlazne karakteristike motora. Stoga će u ovom radu biti detaljno prikazane sve prednosti i mane automatskih mjenjač, te njihov utjecaj na eksploatacijske karakteristike vozila. Less

Abstract (english)

Transmission is one of the most imprtant system on motor vehicles. The role of transmission is to transmit and lead engine power to drive wheels. The gearbox as part of transmission has bigesst part in proces of transmitting and leading engine power to drive wheels. Gearbox has to enable easy vehicle launch, comfort drive, easy vehicle stopping and engine idling. Automatic transmission is in implementation of this actions is easily accessible to driver. Beacuse actions from driver was reduced... More to the minimum, so driver could dedicated to traffic. But automatic transmission disadvantages made them less popular then manual transmission. Higher price, longer time to change gear and less engine output features are some of disadvantages. The appearance of DSG transmission, who seeks to conect advantages of manual and autonatic transmission, made automatic transmission more popular. Construction of DSG transmission made by double clutch and two shafts of transmission, DSG transmission need very short time for change gear, as use of friction clutches which enable maximum engine output features. So in this study will be detail described all advantages and disadvantages of automatic transmission and their impact on vehicle explotation characteristic. Less
