In today's vigorous development of new energy vehicles, how can the gearbox of a fuel vehicle become the focus of the market? This 8AT gearbox, which is installed for the first time on the Xingtu Lingyun, not only makes this mid-level performance SUV a new benchmark in the fuel vehicle market, but also demonstrates the strength of China's automobile industry in technological innovation.
Although Xingtu Lingyun has been on the market for a while, I believe that many people are still curious about this domestically developed 8AT gearbox. This article will take a technical look at the performance characteristics of this gearbox and explore the technical advantages behind it. We hope that through professional analysis and interpretation, we can help you better understand the advantages and potential of this 8AT gearbox.
Self-development is bitter, but breaking the ceiling is cool
Under the general trend of electrification becoming the mainstream, is it still necessary to make great efforts to develop its own 8AT gearbox? Some time ago, the high-end hybrid SUV Xingtu Yaoguang C-DM and the high-end pure electric sedan Xingtu Xingtu Epoch ES were in the limelight, allowing us to see Chery's R&D strength and technological precipitation in the field of hybrid, pure electric and other new energy fields. In the fuel vehicle market, Chery's Arrizo series, Tiggo series, Jietu series, and Xingtu series also have good sales support, which is destined for Chery not to stop the innovation and research and development of fuel power technology.
In order to enhance the competitiveness of products and the upward development of the Xingtu brand, Chery also needs its own 8AT gearbox. Because only leading technology can support a high-end brand image, and blindly relying on procurement technology is obviously unable to be recognized by more consumers. In order to support the ambition and ambition of the Xingtu brand, independent research and development, high-quality three pieces of technology is undoubtedly the best solution.
20 years ago, Chery, which has the title of "science and engineering man in the domestic automobile industry", began to prepare for the development of a domestic CVT continuously variable transmission with independent intellectual property rights. Finally, after 7 years of painstaking self-development, mass production was finally achieved in early 2010. In 2011, Chery's self-developed first-generation CVT continuously variable transmission was installed on Chery Automobile's E5 model. Until 2016, CVT continuously variable transmission was the absolute workhorse of Chery Automobile and became Chery's golden signboard.
In line with the concept of R&D generation, mass production generation, and pre-research generation, Chery Automobile began to pre-develop AT automatic transmissions. In 2016, the first self-developed 6AT automatic transmission sample box rolled off the assembly line, although the road to commercialization was not smooth, but it also accumulated rich technical experience.
Later, Chery's full-stack self-developed 8AT automatic transmission was launched, which is the first domestic new forward development from hardware to software, with complete intellectual property rights, breaking the technical monopoly of foreign brands such as Aisin and ZF in this field, and making up for the gap of independent brands in the field of high-end transmissions.
It is worth mentioning that in the 7th World Test Drive Transmission Selection of the main board of the Automotive Evaluation Research Institute, the full-stack self-developed 8AT gearbox equipped with the new generation of Lingyun for the first time won the reputation of the 7th World Top Ten Transmissions. As the "first in China, the only in the world" gearbox professional evaluation activities, the world's top ten gearbox evaluation combined with objective indicators, subjective evaluation scores, in the transmission technology and market observation is more and more in-depth, has won more and more enterprises, consumers attention and recognition. Chery's self-developed 8AT gearbox, which won the honor of the 7th World Top Ten Gearbox of "Lopal Cup", should not be underestimated.
Technical equality, the ultimate performance of Lingyun
In most cases, high-end transmissions are often exclusive to luxury brands and performance cars. Like the ZF 8AT gearbox, which is currently the mainstream on the market, it usually only appears in BMW, Land Rover and other models. The mechanical transmission efficiency of Chery's full-stack self-developed 8AT gearbox is as high as 96%, reaching the level of international brands, which is comparable to ZF's 8AT gearbox.
This self-developed 8AT gearbox shows excellent adaptability to different driving conditions with a wide range of transmission ratios and excellent performance. For the Lingyun model, the power transmission during acceleration and overtaking is more efficient, and the whole driving process is faster and smoother. Whether on a busy city road or on a smooth highway, this 8AT transmission brings a smooth, smooth and stable driving quality to the driver.
In terms of fuel consumption performance, the optimized transmission ratio and shift logic of Chery's self-developed 8AT gearbox play a key role. According to the data, the WLTC fuel consumption of the 2.0TGDI front-wheel drive model is only 7.7L per 100 kilometers, and the four-wheel drive model is only 8.2L. Compared with the 2.0T models of the same class, this data has obvious advantages. This not only demonstrates Chery's technical strength in energy conservation and emission reduction, but also brings consumers a more economical car cost.
More importantly, Chery's self-developed 8AT gearbox has not only reached the international advanced level in terms of technical performance, but also surpassed the mainstream gearbox in the market in some key performance indicators. For example, the Aisin 8AT and ZF 8AT have a high reputation in the industry and are widely used in many high-end models. However, through comparative testing, it was found that the Chery 8AT gearbox showed good performance in terms of shift speed, transmission efficiency and smoothness. Especially in terms of shift speed, thanks to Chery's optimized control system and precise algorithm, the shift response of its 8AT gearbox is even faster than that of some internationally renowned brands. This not only improves driving comfort, but also further proves Chery's deep strength in the field of transmission technology.
Many car owners are full of praise for this 8AT gearbox after driving for a while: the 8AT gearbox not only shifts smoothly and responds quickly, but also maintains excellent performance in various harsh environments.
Mr. Zhao, the owner of Heilongjiang, said that the weak point of the gearbox will be infinitely magnified in the low temperature environment of Northeast China. Without an excellent gearbox, no matter how strong the engine performance is, it can only be the moon in the water, and the flower in the mirror. On snow and ice, the grip of the tires is greatly reduced, and the viscosity of the lubricating oil increases, which can be said to be a great test for the gearbox. The 8AT gearbox equipped with Xingtu Lingyun shows a world-class level, precise torque management and agile response speed, and still has smooth acceleration and rapid gear shift performance on ice and snow roads. At the same time, its excellent temperature control system and durability also enable the vehicle to perform reliably in continuous high-intensity working conditions.
"In Heilongjiang, which is in an extremely low temperature environment, I can also fully trust Xingtu Lingyun's 8AT. Mr. Zhao said.
Recently, many southern cities have ushered in rainy weather. Mr. Wu, the owner of the car in Suzhou, shared his feelings: when he bought the car, he took a fancy to the 8AT gearbox it was equipped with, firstly, he wanted to support the domestic self-development, and secondly, he also trusted the technology of Chery, a science and engineering man. However, the combination of 2.0TGDI+8AT did not disappoint me. I drive mainly to commute to and from work, and pick up and drop off my children by the way. This set of power drives very silky in urban areas. Recently, it has rained a lot in Suzhou, and there is often water on the road, and the advantages of the 8AT gearbox are reflected in such a road surface, and its precise control allows the vehicle to accelerate smoothly and quickly without skidding.
Traffic problems in large urban areas have always been a nightmare for many car owners. Ms. Wang, a car owner in Beijing, shared her feelings about driving Xingtu Lingyun for 2 months: I am more anxious, and I am in a hurry to do everything, and I am also driving. However, the traffic in Beijing is crowded with people and vehicles, and it is inevitable that there will be some unexpected situations, which will require frequent sudden braking. The 8AT transmission can still provide a smooth power drop during frequent downshifts, so that the vehicle can stop accurately and smoothly at the designated position, which makes me feel at ease.
"It's really reassuring for me to drive the clouds. Ms. Wang expressed her trust and love for Xingtu Lingyun.
Through the sharing of real car owners, it is not difficult to see that this power system, especially this 8AT gearbox, has undoubtedly reached the world-class level, and the ultimate experience it brings is becoming the core competitiveness of Xingtu Lingyun that distinguishes it from its joint venture competitors at the same level.
Summary:
The self-developed 8AT gearbox equipped with Xingtu Lingyun shows a world-class high level in terms of smoothness of gear shifting, responsiveness and smoothness of transmission. It is also with the power combing of this 8AT gearbox that the 2.0T national top ten engine equipped with Xingtu Lingyun can better exert its strength and redefine the value benchmark of performance SUV.
The success of Chery's self-developed 8AT gearbox is not only a milestone in the technological innovation of China's automotive industry, but also a symbol of the independence and self-improvement of Chinese brands in the research and development of core components. Its successful R&D and application have announced to the world the profound technology accumulation of China's automobile industry and its firm determination to enter the high-end market.
