20 10 models are equipped with 5AT gearbox, and 20 14 models are equipped with 6-speed wet dual-clutch gearbox. Although 5AT is an old product of Aisin, its reliability is still good. 6-speed wet dual clutch has independently developed SAIC and Borgwarner.
2.20 17 second generation MG6 gearbox
Starting from the 20 17 model, it is equipped with TST7-speed dry dual-clutch gearbox. DCT250 gearbox is jointly developed by SAIC and General Motors. The performance of this gearbox is not satisfactory, and it has been criticized by the owner as a setback, abnormal sound and high failure rate. This problem is not only reflected in the MG6 model, but also in the SAIC model using this gearbox. The second-generation MG6 will suffer forever because of this dry dual-clutch gearbox.
3.2020 Third Generation MG6 Gearbox
It will be equipped with AM2 17 speed wet dual clutch gearbox. This DCT280 seven-speed wet dual clutch is produced by Shanghai Automobile Transmission Co., Ltd., and the maximum load torque is calibrated at 280Nm. In August of 20 18, SAIC reformed the assembly line of DM2 1 wet and dry dual-purpose gearbox, and mass-produced it in 20 19. DM2 1 seven-speed wet dual-clutch gearbox is developed on the basis of dry DCT250 product, which has better driving performance and stronger load-bearing capacity.
4. Development status of dual clutch gearbox
As one of the core components of power shift, the dual clutch module is mainly produced by Luke Company of Schaeffler Group in Germany and Borgwarner Company in the United States. LuK is a company that develops and manufactures transmission parts. At present, only a few manufacturers in the world, such as Luke and Valeo, produce dry dual clutch. Borgwarner is an American multinational auto parts manufacturer. Many domestic automobile companies claim to have developed dual clutch gearboxes. In fact, Borgwarner is behind them.
AT gearbox technology patents are basically concentrated in Aisin and ZF, and CVT gearbox core components are basically concentrated in Bosch and Schaeffler. It is very difficult for brands to independently develop AT gearboxes and CVT gearboxes, and their maturity and experience are also worse than those of some developed products. However, the structure and basic principle of the dual-clutch gearbox are the same, and the underlying technology of the dual-clutch gearbox is not in the hands of one manufacturer.
In the field of wet dual-clutch gearbox, the seven-speed wet dual-clutch of Great Wall, Geely and other manufacturers performed very well. At present, R & amp；; Strong D car companies all produce their own dual-clutch gearboxes, such as Great Wall Honeycomb Transmission 7DCT, Geely 7DCT and Qisheng Power 7DCT. , and R &；; D most car companies with weak strength outsource dual-clutch gearboxes such as Getrag7DCT.
1.5T/2.0T turbocharged engine +7-speed wet dual-clutch power system will become more and more popular in the later period, and the 7-speed wet dual-clutch gearbox of the third generation MG6 is worth looking forward to!
