双离合变速箱已经到维修期了，AT的修的反而少了。双离合变速箱分为干式双离合和湿式双离合。最近几年湿式双离合变速箱装车比较多。

　　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.

　　干式双离合的两个离合器片是集成在一起的（可以理解为两个手动挡离合器片替换着工作），离合器片暴露在空气中，不沾水不沾油，沾了会坏，所以叫干式双离合。优点：传动效率高，换挡速度快，适合大油门驾驶，变速箱轻，用油量少。缺点：散热不好，低速和大公里数换挡顿挫。

　　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.

　　湿式双离合的离合器片基本上都是多片式离合器（好几张离合器片）浸在变速箱油里面。优点：传动效率高，散热较好，换挡平顺，耐用。缺点：有动力损失，变速箱用油量大（和AT差不多）维护成本高。

　　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.

　　装这款变速箱的车子不多，保有量也少，维修量就少了。问题很明显，离合器、分离轴承、拨叉，都严重锈蚀。水是从哪来的？下雨、洗车、车子趟水……离合器就有可能会进水，进水以后排不出去，时间长了就生锈损坏。

　　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.
