Automatic transmission, Chongqing Lancome
Lancome 6AT has complete intellectual property. Landmark
Since the start of the research and development of AT transmission in 2015, Lancome has not been afraid of many difficulties in development technology and short development cycle. The project team has been able to stabilize and overcome difficulties, and finally realize the industrialization of the project.
Qin Wenmin, deputy secretary of the District Committee of Chongqing Laoshan District, and the head of the district people's government
Deputy Secretary Qin Wenmin said in his speech that Lancome is a leading manufacturer of automotive core components that has been cultivated and grown up in Laoshan. It is also the first listed company cultivated in Laoshan. It can be said that Lanxie Company is a model representative of the continuous growth and growth of Lushan manufacturing enterprises. It is the backbone of Lushan's industrial development and has made due contributions to the economic and social development of Lushan. The Lancome 6AT assembly is officially launched, which is conducive to the company's promotion of competitiveness, expansion of target market and enhancement of technology accumulation. It will inevitably inject more powerful momentum into the development and growth of the company, and accelerate the take-off of the company. , laying a more solid foundation.
Zhu Tangfu Chairman of Chongqing Lancome Power Transmission Machinery Co., Ltd.
Chairman Zhu Tangfu said that LD6AT has emboldened the efforts of more than 200 engineers and technicians from Blue Dragonfly, and the support of many well-known parts suppliers at home and abroad. The company has taken the road of “taking me as the mainstay and joint research and development”. Independent intellectual property rights, its downline has an important milestone for the independent brand of Lancome.
It is reported that the Lancome 6AT transmission strictly follows the GPDP development process and has undergone rigorous DVP verification during product development. The products have experienced a total of more than 20,000 hours of comprehensive bench test; cumulatively passed more than 1.5 million kilometers of various road endurance tests, successfully passed the "three high" test assessment of high temperature, high altitude and high cold. Under the leadership of the project team leader Mr. Tang Haichuan, the software and control strategy team worked day and night, completed the preparation and modification of nearly 100,000 lines of code, and released more than 10 versions of the control software at different stages, and launched hundreds of times. Sex calibration testing and verification.
Through the research and development of 6AT transmission, Lancome has applied for 6 invention patents and 12 utility model patents, which has enabled the company to truly embark on the road of product transformation and technological innovation. Compared with the current domestic mainstream automatic transmission, the product has a certain improvement in handling, NVH and transmission efficiency. Multi-gear, tight gear ratio changes make the product power connection smoother and shift faster. At the same time, the company has many years of experience in the manufacture of teeth, shafts and housings, enabling more cost control and providing customers with more cost-effective products.
Qin Wenmin, deputy secretary of the Lushan District Party Committee of Chongqing Municipality and district head of the district people's government, and Zhu Tangfu, chairman of Chongqing Lancome Power Transmission Machinery Co., Ltd. jointly unveiled the Lancome 6AT transmission
Chairman Zhu Tangfu said that the success of the 6AT project has laid a solid foundation for the strategic transformation of Lancome products. In the near future, Lancome will continue to introduce more cost-effective products according to national industrial policies and industry technology development, to provide customers with more excellent driving experience and use value.
5 core technology highlights to promote industry level
At the unveiling ceremony of the Lancome 6AT assembly, Tang Haichuan, deputy general manager of Chongqing Lancome Power Transmission Machinery Co., Ltd. introduced the highlights of 6AT products. The first is higher transmission efficiency. Under the 168 working conditions, the transmission efficiency is effectively increased by 0%-3% compared with the mainstream products in the industry, further improving fuel economy. Second, it has the function of autonomous self-learning. Built-in Sub-Rom solution, the test data of the offline gantry is directly written to the Sub-Rom built in the transmission, and the TCU directly reads the initial data in the Sub-Rom, instead of the initial self-learning when the whole vehicle goes offline, effectively shortening The entire vehicle is off the assembly line. Third, platform design. Blue Dragonfly 6AT has three series A, B and C, 95% of which are shared by shaft, clutch, hydraulic system and parts; it can meet production line compatibility and fast switching; core components such as hydraulic control system, planetary transmission system, etc. are compatible with 8AT And P2 hybrid architecture. Fourth, the use of two-stage shock absorption technology. The two-stage shock absorber of the torque converter is used to cope with the worse engine torsional vibration, which is beneficial to the NVH lifting. At the same time, the torque converter has a lower locking speed (1200 rpm) and lower fuel consumption. Fifth, the hydraulic system is upgraded. When the Lancome 6AT is in the N position, the conventional on-off valve control is switched to the hydraulic pressure of the C3 solenoid valve control B2, and the brake of the B2 brake is in the N-R process, thereby reducing the N-R shift shock.
Li Shengqi, Secretary General of China Automotive Automatic Transmission Innovation Alliance, Secretary General of China Europe Association Gear Transmission Industry Branch
Li Shengqi's secretary-general highly recognized the performance of the Lancome 6AT. He said that the downline of the Lancome 6AT is not only the glory of all employees of Lancome, but also a major event in China's transmission industry. Especially in the current fierce market competition, the internal and external environment is complex, and the automotive industry's transformation and upgrading tasks are arduous, Lancome's breakthrough in the field of automatic transmission has enhanced the confidence of the industry. At present, Lancome 6AT has achieved success in research and development, and its excellent product performance and high cost performance will help it to go further and further on the market.
An Qingheng Director of China Automotive Industry Advisory Committee
In recent years, with the rise of a group of independent transmission companies such as Lancome, China's automatic transmission has made substantial progress. Director An Qingheng said that in 2016, passenger auto-automatic transmissions accounted for only 7%, and by 2018, the proportion rose to 20%. In recent years, in the field of automatic transmissions, many independent car companies have invested heavily and the overall situation has become better. China's automakers are growing, China's transmission industry is also growing, and the self-owned brand's automatic transmissions have made great progress, making significant progress in breaking the core technology blockade of automatic transmissions and forming electrification preparations. The product performance, reliability, energy saving effect and cost control of the autonomous transmission have been greatly improved, and the product development system has been continuously improved.
After the unveiling ceremony, the guests also visited the production line of the Lancome 6AT assembly and experienced the model equipped with the Lancome 6AT automatic transmission. The production process and product performance of Lancome 6AT have been unanimously recognized by them.
