只要你有油車,那就絕對離不開變速箱,目前市面上有 MT 、 AT 、 CVT 、 DCT,這四種常見的變速箱,他們都有什么優點呢,又適合什么樣的人,今天一篇文章帶你全面了解。

　　As long as you have a gasoline powered car, you absolutely cannot do without a gearbox. Currently, there are four common gearboxes on the market: MT, AT, CVT, and DCT. What are their advantages and what kind of people are they suitable for? Today's article will take you through a comprehensive understanding.

　　首先，傳統的手動變速箱,也就是 mt 變速箱,優點在于耐用性好、故障率低,包括后期的維修成本它也不高,但它需要駕駛員在車輛的行駛中,頻繁手動操作去加減檔位,麻煩,而且操作呢，復雜,對于駕駛員的技術有著一定的要求,能給駕駛者帶來操縱的樂趣,適合于那種人車合一的技術

　　Firstly, the traditional manual gearbox, also known as the MT gearbox, has the advantages of good durability, low failure rate, and low maintenance costs. However, it requires the driver to frequently manually adjust the gears while the vehicle is in motion, which is troublesome and complex to operate. It has certain requirements for the driver's skills and can bring joy to the driver's operation. It is suitable for the technology of integrating people and vehicles

　　第二種，液力自動變速箱,也就是 a at 變速箱,是目前絕大多數車主心目中最完美的變速箱,技術成熟，而且駕駛舒適性好，不容易壞,可靠性強,能承受大扭矩,但無論油耗還是后期的保養費用都相對較高,適合于那種想省心不差錢的大哥們

　　The second type, hydraulic automatic transmission, also known as a at transmission, is currently the most perfect transmission in the minds of the vast majority of car owners. It has mature technology, good driving comfort, is not easy to break, strong reliability, and can withstand high torque. However, both fuel consumption and later maintenance costs are relatively high, making it suitable for those who want to save time and money

　　第三種，機械無級自動變速箱,也就是 CVT 變速箱,最大的優點就是換擋平順,油耗低,非常適合于家用,缺點就是加速度反應慢,無法承受太高的扭矩,容易打滑,目前市面上最常見的為鋼帶式和鋼鏈式的兩種,其中鋼鏈式的要比鋼帶式的要好,因為鋼鏈式可以承受更大的扭矩,而且相比于鋼帶式更不容易打滑,并且在傳動效率上也要比鋼帶式的要高,這種變速箱呢，非常適合于那種佛系開車,非常樂意刷新油耗的省錢擋。

　　The third type is the mechanical continuously variable automatic transmission (CVT), which has the biggest advantages of smooth shifting and low fuel consumption, making it very suitable for household use. The disadvantage is that the acceleration response is slow, and it cannot withstand too high torque, making it easy to slip. Currently, the most common types on the market are the steel belt type and the steel chain type. The steel chain type is better than the steel belt type because it can withstand greater torque and is less likely to slip compared to the steel belt type. It also has higher transmission efficiency than the steel belt type. This type of transmission is very suitable for Buddhist driving and is willing to refresh fuel consumption to save money.

　　最后雙離合變速箱,也就是 DCT 變速箱,最大的優點就是換擋速度快,并且傳動效率高,燃油經濟性呢也不錯,很多跑車都在用雙離合,一般分為干式和濕式的兩種,其中濕式雙離合要比干式的更耐用,但在換擋速度上它不如干式快,并且干式雙離合更容易出現過熱故障,適合于那種大開大合的地板油,開車風格有點偏激烈的性能黨,追求加速度和爽感的那批人。

　　Finally, the dual clutch transmission, also known as DCT transmission, has the biggest advantage of fast shifting speed, high transmission efficiency, and good fuel economy. Many sports cars use dual clutch transmission, which is generally divided into dry and wet types. Wet dual clutch transmission is more durable than dry transmission, but it is not as fast in shifting speed as dry transmission, and dry dual clutch transmission is more prone to overheating faults. It is suitable for those who use floor oil with wide opening and closing, have a slightly aggressive driving style, and pursue acceleration and comfort.
