哈弗品牌是长城汽车的销售主力，旗下多数车型匹配来自韩国现代派沃泰公司和格特拉克公司的自动变速箱。有媒体从长城汽车官方获悉：长城汽车自主研发和生产的7速双离合变速器已搭载在WEYVV7车型上，未来将实现H2车型到VV7、H7等车型的全覆盖。长城汽车将停止与韩国现代派沃泰变速箱公司的合作。早年间，中国品牌车企还没有量产自动变速箱的能力，只能寻求国外变速箱供应商。长城汽车也不例外，哈弗H6上搭载过现代派沃泰（Powertech）6AT变速箱，现款H6和H6Coupe上使用了格特拉克的7DCT变速箱。现如今长城自主研发7DCT变速箱已经量产，并率先在WEYVV7车型上搭载。长城汽车传动研究院副院长兼项目总监郑立化表示，7DCT450除了达到最优的产品质量，还具有适合整车所有平台的设计，满足了高产量的需求，在零部件、软件及标定、生产设备具有优秀的供应商系统，已具备批量的自制能力。目前7DCT450变速箱产能为50万台/年，并不能满足长城汽车年销百万辆以上整车的需求，部分车型将匹配来自格特拉克的7速双离合变速箱，待2018年长城汽车变速箱工厂二期项目投产后，产能将增至100万台/年，从H2S到H6、H7和WEY系列将逐步搭载这款7速双离合变速箱。
Great Wall ends transmission supply cooperation with Hyundai Powertech
Haval, the main sales driver for Great Wall Motors, equipped many models with automatic transmissions supplied by Korean Hyundai Powertech and German Getrag. But a local media got information from the Chinese automaker that as its own 7-speed dual-clutch transmission has been fitted into WEY VV7 and will be used in all models covering Haval H2 and H7, it will stop the cooperation with Hyundai Powertech.
In the older days, Chinese auto brands were unable to mass produce automatic transmissions and had to turn to foreign suppliers. Haval H6 was once equipped with 6AT from Hyundai Powertech and the current H6 and H6 Coupe are with 7DCT from Getrag. With the technology advancement, GWM can mass produce its own 7DCT now, which has been fitted in WEY VV7.
Zheng Lihua, the associate dean of GWM’s Transmission Research Institute and project director, said that its 7DCT450 boasts an optimal product quality and is suitable for all vehicle platforms’ design. The automaker has outstanding supplier systems in auto parts, software and calibration as well as production equipment.
At present, the annual output of 7DCT450 is 500,000 units, which cannot meet the needs of the automaker’s 1 million sales target. As a result, some models will continue to use transmissions supplied by Getrag. As long as the second phase of the transmission factory starts production, the output will be doubled. Haval H2S, H6, H7 and WEY models will be equipped with this 7-speed dual-clutch transmission in the future.
