只要你有油车,那就绝对离不开变速箱,目前市面上有 MT 、 AT 、 CVT 、 DCT,这四种常见的变速箱,他们都有什么优点呢,又适合什么样的人,今天一篇文章带你全面了解。

　　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，传统的手动变速箱,也就是 mt 变速箱,优点在于耐用性好、故障率低,包括后期的维修成本它也不高,但它需要驾驶员在车辆的行驶中,频繁手动操作去加减档位,麻烦,而且操作呢，复杂,对于驾驶员的技术有着一定的要求,能给驾驶者带来操纵的乐趣,适合于那种人车合一的技术

　　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

　　第二种，液力自动变速箱,也就是 a at 变速箱,是目前绝大多数车主心目中最完美的变速箱,技术成熟，而且驾驶舒适性好，不容易坏,可靠性强,能承受大扭矩,但无论油耗还是后期的保养费用都相对较高,适合于那种想省心不差钱的大哥们

　　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

　　第三种，机械无级自动变速箱,也就是 CVT 变速箱,最大的优点就是换挡平顺,油耗低,非常适合于家用,缺点就是加速度反应慢,无法承受太高的扭矩,容易打滑,目前市面上最常见的为钢带式和钢链式的两种,其中钢链式的要比钢带式的要好,因为钢链式可以承受更大的扭矩,而且相比于钢带式更不容易打滑,并且在传动效率上也要比钢带式的要高,这种变速箱呢，非常适合于那种佛系开车,非常乐意刷新油耗的省钱挡。

　　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.

　　最后双离合变速箱,也就是 DCT 变速箱,最大的优点就是换挡速度快,并且传动效率高,燃油经济性呢也不错,很多跑车都在用双离合,一般分为干式和湿式的两种,其中湿式双离合要比干式的更耐用,但在换挡速度上它不如干式快,并且干式双离合更容易出现过热故障,适合于那种大开大合的地板油,开车风格有点偏激烈的性能党,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.
