Difference Between Wet and Dry Dual-Clutch Transmissions
1 Answers
Dry and wet dual-clutch transmissions differ primarily in the medium connecting the driving plate and the driven plate. Below are the specific differences between the two: 1. The medium connecting the driving plate and the driven plate differs; dry dual-clutch transmissions rely on air for transmission, whereas wet dual-clutch transmissions use oil. 2. Mechanical transmission efficiency varies: Wet dual-clutch transmissions require hydraulic pumps, lubricating fluid, cooling pipes, and external cooling systems, resulting in lower mechanical transmission efficiency. In contrast, dry dual-clutch transmissions, to reduce costs, often feature lightweight or omitted hydraulic systems during production, giving them an advantage in space structure optimization. Additionally, because dry dual-clutch transmissions lack hydraulic assistance, their transmission efficiency is higher, offering better fuel economy compared to wet dual-clutch transmissions.
