What is the method to distinguish between dry and wet dual-clutch transmissions?
1 Answers
Dry and wet dual-clutch transmissions are two different types of dual-clutch systems. The method to distinguish between them is as follows: The primary way to differentiate dry and wet dual-clutch transmissions is to check whether the clutch friction plates contain lubricating oil. If the clutch friction plates are immersed in lubricating oil, it is called a wet type; otherwise, it is called a dry type. The advantages and disadvantages of dual-clutch friction plates are introduced below: 1. The friction plates of a wet dual-clutch transmission are submerged in transmission oil, which provides cooling and lubrication, allowing it to withstand greater loads. However, because more space is required to store the transmission oil and related control mechanisms, the wet dual-clutch friction plates are larger in size and more complex in structure, leading to reduced power transmission efficiency. 2. On the other hand, a dry dual-clutch transmission omits these components, resulting in a simpler structure and higher transmission efficiency. However, the drawback is that the lack of cooling from transmission oil means the friction plates are more prone to overheating and burning, which limits the maximum torque that can be transmitted.
