FAW Liberates AMT Truck Delivery Users
At 8:30 a.m. on December 8, 2008, Wutai Fuxin's newly-released J5P 6*4 tractors matching FAW's self-developed AMT system were placed in front of the technical center of FAW Group's technical center, and five cars were welcomed. user. The launch ceremony for the users of the automatic transmission (AMT) of FAW Jiefang heavy-duty trucks was held here. As the first domestic commercial vehicles that match the AMT system, the market launch of these five vehicles has filled the gap in the domestic commercial vehicle market.
FAW is an earlier company that entered the field of technology research and development of automatic transmissions. As early as 2001, they carried out research and development of AMT products and independently developed the domestic technology-leading FAW-brand passenger cars and passenger car automatic transmission products. Since 2004, FAW has started to develop AMT products for heavy-duty trucks because it is still a blank reality for domestic truck AMT. Thanks to their strong electronic control research and development capabilities, they have completed all R&D of key components and software such as vehicle shift control and control strategy systems, AMT computers, selected shift actuators, and automatic gear levers in just over a year. Work, and has the electronic control system software and hardware, select shift actuators, clutch actuators, shift joysticks, display panels and other independent intellectual property rights. In 2006, the "AMT" system independently developed by FAW entered the productization stage. In order to ensure the quality and stability of the components, FAW aims to establish an independent supporting system. Through extensive communication, cooperation and specific guidance with suppliers, FAW has cultivated the manufacturing capabilities of its suppliers to meet the performance indicators of its components. Quality and reliability. At present, the performance indexes of some components of the AMT system have reached the international level and have laid a solid foundation for meeting batch production.
FAW's self-developed commercial vehicle AMT is based on FAW's existing manual transmissions. It adds an automatic transmission control system. The electronic control unit controls the shift actuator and clutch actuator. Through communication with the engine, automatic selection is achieved. Gear shift, clutch and throttle operation to achieve automatic transmission shifting of the manual transmission. It has both manual and automatic modes of operation. In the automatic mode, gear shifting and clutch disengagement are all controlled by the AMT Computer (TCU) and do not require the driver to perform any operation. In the manual mode, the driver can complete shifting by operating the shift control handle. . In order to adapt to the conditions of use of the truck and ensure safety, the AMT system retains the clutch pedal. When the driver shifts gears in the starting mode or shifts the vehicle in the manual mode, the driver needs to operate the clutch to shift gears.
The AMT system developed to meet China's national conditions and meet the requirements of China's highways has the characteristics of low production cost, high transmission efficiency, and reduced fuel consumption. Compared with the same type of manual transmission, the AMT system can save more than 5% of fuel.
Focusing on leading the commercial vehicle automatic transmission market, FAW's self-developed AMT system will be targeted at high-end heavy-duty commercial vehicles for road use. It will be matched to the FAW flagship market, the Liberation Aowei and J6 series models.
