What Does Dual-Clutch Two-Wheel Drive Mean?
1 Answers
Two-wheel drive dual-clutch refers to a front-wheel drive system with a dual-clutch transmission. The specific details are as follows: 1. Types of Car Transmissions: Car transmissions can be divided into two main categories: manual transmissions and automatic transmissions, which correspond to the well-known manual and automatic gearboxes. Automatic transmissions can be further subdivided into four types: AT (automatic transmission), AMT (semi-automatic transmission), DTC (dual-clutch transmission), and CVT (continuously variable transmission). The dual-clutch transmission discussed here is essentially an automatic transmission. 2. Concept of Dual-Clutch: Dual-clutch refers to a dual-clutch transmission, which essentially means there are two sets of clutches working simultaneously—one managing the odd-numbered gears and the other managing the even-numbered gears. This design aims to avoid the power interruption issue during gear shifts in traditional manual transmissions, achieving faster gear changes. Different manufacturers have different names for dual-clutch transmissions: Volkswagen calls it DSG, Audi calls it S-tronic, and Porsche calls it PDK, among others. 3. Pros and Cons of Dual-Clutch: The advantages of dual-clutch transmissions are quite evident, such as high transmission efficiency, fast gear shifts, low production costs, compact size, and low fuel consumption. In terms of advantages, they can easily outperform conventional AT transmissions. However, to date, all dual-clutch transmissions suffer from drawbacks like low-speed jerking and relatively poor reliability. There have been numerous recalls due to dual-clutch failures or design defects.
