AMT gearbox, main force of truck automatic transmission, good mechanical performance, relatively easy to control manufacturing cost, are widely used in trucks. In Europe, it has not been a smooth process. After decades of accumulated technology, European vehicles matching AMT can account for 70% of the total. And everywhere in Europe, vehicles equipped with AMT in China can be described as “Feng Feng Maoâ€, and the popularity of domestic AMT will take some time.
It has been originated in Europe for several decades. In the 1960s, Europe began to study AMT. After decades of evolution, it started with the semi-automatic AMT to fully automatic AMT. The current AMT can be described as intelligent. AMT development process is relatively bumpy, at the beginning of the European problem is endless, with the strong input of many manufacturers, as well as the progress of electronic technology, after years of development, AMT is now very mature.
At present, Europe can be said to be the leader of AMT. The famous Mercedes-Benz Power-Shift automatic transmission, Volvo's I-shift, ZF AS-Tronic and so on. Its matching models have been introduced and sold domestically. Domestic drivers have given high ratings to vehicles that match AMT. Driving without shifting becomes a reality, and fuel consumption is also good. This is a universal evaluation of drivers driving AMT vehicles.
Yet the popularity of ready-made to AMT <br> <br> AMT currently the penetration rate of less than 1% in 2008, can be said that China truck AMT first year, in October 2008 assembly liberation assembled nine speed AMT delivery models Users, opened the curtain of China Truck AMT era. The subsequent listing of AWT's Howo A7 in December was a further boost to AMT's promotion in the domestic market, officially opening the AMT era for China's trucks.
Although domestic 2008 is the first year of domestic AMT, due to the imperfection of AMT at the beginning of the listing, the user experience is not very good. As a result, users are afraid of AMT, and users are distressed by various problems. AMT's development path is more difficult. Caused many AMT users to change the gearbox back to manual. The most frequently reported by the user is the inaccurate shift timing of the AMT. It is not possible to perform the lift gear according to the driver's intention. The main problem is system calibration optimization. As for the mechanical parts of the domestic AMT, it is still very reliable and there are no mechanical problems leading to vehicle outages.
After years of development, the domestically produced AMT gearbox is very stable. It is understood that the largest number of models that match the Liberation AMT has already operated 700,000 kilometers, and the heavy-duty AMT vehicles also have over one million. The current AMT system can still work normally. After many years of optimization, the AMT shift logic has been very scientific. It can lift and lower gears according to the driver's intentions, and the shift smoothness is also good. The impact of shifting is barely noticeable.
Two factions VS electric current domestic gas control <br> <br> AMT There are three, namely: liberation, heavy truck, Fast three, which is currently used in the liberation of electronically controlled program, heavy truck, Fast The air control program was used in cooperation with WABCO. Liberation and heavy-duty AMT have been applied in mass production vehicles, and Fast's AMT has not yet been widely used.
The liberation of AMT is an electronic control scheme, and key components such as shift actuator motors come from Bosch. After several rounds of road tests, the actual use of users, the reliability is still guaranteed, the control program has reached the 15th edition, the market's user feedback is good. The price of matching AMT models is just over 10 million more than that of manually-blocked models, which is fairly acceptable to users. More money is spent in exchange for this million dollars for better driving experience. Because there is no need to shift gears, the intensity of driving vehicles is reduced, and long-time driving will not feel too tired.
Heavy-duty trucks and fast gas are used in the air control program. The technology comes from WABCO. The solenoid valve controls the compressed air to push the shifting structure to complete the shift action. Heavy Truck's AMT has been on the market for eight years since 2008. At present, the control program of Heavy Truck's AMT has been developed to the 42nd edition, and shift logic and ride comfort have been very good. As the gearbox leader in China and even in the world, Fast has also introduced the AMT gearbox. Currently, it is only used on a few vehicles and has not been widely promoted.
The birth of new things will inevitably go through a process of growth, and so will AMT. After years of experience, the domestic AMT has matured, and it is not only foreign monks who will read the scriptures. The domestically produced AMT can also do very well. At present, more and more vehicles are equipped with AMT, and daily use has a good performance. In the increasingly younger drivers, and the ever-increasing requirements for vehicle comfort, truck-matching AMT will be a general trend.
