雙離合變速箱已經(jīng)到維修期了，AT的修的反而少了。雙離合變速箱分為干式雙離合和濕式雙離合。最近幾年濕式雙離合變速箱裝車比較多。

　　The dual clutch transmission has reached the maintenance period, and there have been fewer repairs on the AT. Dual clutch transmissions are divided into dry dual clutch and wet dual clutch. In recent years, wet dual clutch transmissions have been installed more frequently.

　　干式雙離合的兩個(gè)離合器片是集成在一起的（可以理解為兩個(gè)手動(dòng)擋離合器片替換著工作），離合器片暴露在空氣中，不沾水不沾油，沾了會(huì)壞，所以叫干式雙離合。優(yōu)點(diǎn)：傳動(dòng)效率高，換擋速度快，適合大油門駕駛，變速箱輕，用油量少。缺點(diǎn)：散熱不好，低速和大公里數(shù)換擋頓挫。

　　The two clutch plates of the dry dual clutch are integrated together (which can be understood as two manual transmission clutch plates replacing each other). The clutch plates are exposed to the air and do not get wet or oily. If they get wet, they will break, so it is called dry dual clutch. Advantages: High transmission efficiency, fast shifting speed, suitable for driving with high throttle, light gearbox, and low oil consumption. Disadvantages: Poor heat dissipation, jerky shifting at low speeds and high mileage.

　　濕式雙離合的離合器片基本上都是多片式離合器（好幾張離合器片）浸在變速箱油里面。優(yōu)點(diǎn)：傳動(dòng)效率高，散熱較好，換擋平順，耐用。缺點(diǎn)：有動(dòng)力損失，變速箱用油量大（和AT差不多）維護(hù)成本高。

　　The clutch plates of wet dual clutch are basically multi plate clutches (several clutch plates) immersed in transmission oil. Advantages: High transmission efficiency, good heat dissipation, smooth gear shifting, and durability. Disadvantages: Power loss, high oil consumption in the transmission (similar to AT), and high maintenance costs.

　　裝這款變速箱的車子不多，保有量也少，維修量就少了。問(wèn)題很明顯，離合器、分離軸承、撥叉，都嚴(yán)重銹蝕。水是從哪來(lái)的？下雨、洗車、車子趟水……離合器就有可能會(huì)進(jìn)水，進(jìn)水以后排不出去，時(shí)間長(zhǎng)了就生銹損壞。

　　There are not many cars equipped with this gearbox, and the number of ownership is also small, resulting in less maintenance work. The problem is obvious, the clutch, release bearing, and shift fork are all severely corroded. Where does water come from? Rainy weather, car washing, and water running in the car... the clutch may get wet, and once it gets wet, it cannot be discharged. Over time, it will rust and become damaged.
