In the last 20 years, China’s auto industry was acquiring technologies steadily through forming joint venturing and buying product lines. However, until now, China doesn’t have a mature manufacturing base for Automatic Transmissions.
Things are changing now. In the second decade of the 21st centaury, China decides to skip the Automatic Transmission stage, directly deploying next generation technology--- DCT, to its fast growing auto industry. This new gear box is smaller and lighter that traditional automatic gear box, offering benefits such as better driving experience and better fuel economy to drivers. In next 2 years, you will see VW, Borg Warner, Getrag, and China owned Qing Shang launching their own Dual Clutch Transmissions. The full capacity invested will be around 1.5 million boxes per year.
Among all the DCTs which will be launched in China, VW’s DQ200 will be the star. This new seven-speed gearbox adopts a pair of dry, organic bonded friction linings that do not require cooling, making the drive-train more efficient through the extra ratio and the fact that less power is required for the gear selection and clutch servo system. Since the clutch does not require cooling the quantity of oil was reduced from 7-litres in the six-speed DSG gearbox to only 1.7-litres in the new seven-speed system. Measuring only 369 mm in length and weighing only 79 kg including the dual-mass flywheel the gearbox is remarkably compact.
The adoption of DCT technology will make China’s car industry much “Greener” and more energy efficient. The spare part distributor should pay attention to this new trend, adding new product lines to the inventory to meet the future demands.
