Why do domestic cars prefer to use dual-clutch transmissions?
1 Answers
Domestic cars prefer to use dual-clutch transmissions for the following reasons: 1. Low production cost: Although the initial investment in dual-clutch production is relatively high and the per-unit cost is higher, the cost can be reduced by more than half as it becomes more widespread, making it much cheaper compared to transmissions from Aisin and ZF. 2. Simple production process: After more than a decade of development in the automotive industry, domestic mainstream car manufacturers have gained rich experience in the production technology and R&D of manual transmissions. The machinery and equipment used to produce manual transmissions can be directly repurposed for dual-clutch transmissions, and previous production experience can also be applied to the R&D and production of dual-clutch transmissions. 3. Avoiding technological barriers and achieving overtaking in corners: Traditional AT automatic transmission technology is already mature, and domestic manufacturers started late in this field, making it difficult to achieve breakthrough development. However, the technological gap in dual-clutch transmissions is smaller, and domestic manufacturers can strive to overcome core technologies to achieve overtaking in corners. 4. Low technical threshold: The patents for AT and CVT transmissions are largely monopolized by foreign transmission giants. However, the technological gap for dual-clutch transmissions is smaller, and the technical threshold is lower. For example, Great Wall independently developed a 7-speed wet dual-clutch transmission, whose dual-clutch module was developed by BorgWarner.
