With the review of the products by the review committee and the successful completion of the test of the Tianjin bus , Zhongtong's new energy-saving and environmental protection bus has become an example of successful cooperation between upstream and downstream industrial chains such as vehicle manufacturers, parts factories, and users.
On December 19th in the “Energy-saving and Environmental Protection Bus Alliance†bus passenger car seminar on new energy-saving environmental protection, Zhang Bingrong, director of the Ministry of Science and Technology of the Urban Vehicle Expert Committee read the expert opinion on the review committee: the project results have reached the same domestic type The leading level of the bus has been approved by the project unanimously and it is recommended to promote it in the bus industry.
Ye Dongqiang, Secretary-General of the Science and Technology Branch of the China Urban Transport Association, introduced that this new type of energy-saving and environmental-friendly bus has three innovations, that is, the quality of trimming is light; the matching is done well; the bus company takes the lead, the vehicle production plant and the parts and components plant together Collaborate on product development.
Upstream and downstream linkages
November 7, 2008, initiated by the Urban Vehicles Expert Committee of the Science and Technology Commission of the Ministry of Construction, the Science and Technology Sub-association of the China Urban Public Transport Association, and the China Gear Association, and the joint bus company, passenger car and parts manufacturing company formed the “Energy Saving and Environmental Protection Bus Innovation†alliance". Zhongtong Bus is mainly responsible for this project, and has gathered together Guangxi Yuchai, Allison Transmission, Tianjin Zhongde Transmission Company, Dongfeng Dana Axle and other companies for joint R&D.
In particular, "as the main body of each public transport company, not only in the early stage of research and development, but also in response to its own urban road conditions, it is required to submit product performance requirements to the entire vehicle company, and to be responsible for the probation of energy-saving and environmental-friendly buses during the later period of research and development, and to track the collection of trial vehicles. Data and suggestions for improvement: The product platform takes the OEM as the main body, organizes various parts and components companies, and jointly develops parts and components such as engines, transmissions, rear axle main reducers, and tires that are suitable for specific operating conditions to realize the entire vehicle. Energy saving.†Li Shihao, chairman of the China Municipal Public Transportation Association Science and Technology Branch, said.
The practice of purchasing vehicles in the public transportation industry is point-based system. Bus companies are generally what the bus companies need to produce, but whether the products are really suitable is not necessarily, and the vehicle manufacturers are also passive.
In a sense, although the “Energy-saving and Environmental Protection Bus Innovation Alliance†model is also a requirement put forward by users, the OEM has developed a joint component factory. After the product comes out, a user actively cooperates with the trial and procurement process. . In this way, through the linkage between upstream and downstream companies, it is possible to develop products that are suitable for the road conditions and operational needs of the city as well as the initiative of the production companies.
Saving 10%
The results did not disappoint.
When Li Daoxin, deputy general manager of Tianjin Public Transport Group, introduced the test results of the LK6210GT energy-saving and environmentally friendly products on the bus line in Tianjin, the attention of the participants was concentrated. LCK6210GT this product in the end how energy-saving performance? Tianjin bus has the most say. From September to November this year, Tianjin Bus trialed two LCK6120GT buses , equipped with manual transmissions and automatic transmissions, and put in different lines to carry out no-load and actual operation tests.
Li Daoxin read a set of data at the meeting: From September 27 to November 10, two test vehicles were continuously operated on four lines of Tianjin Bus for 45 days, and the total mileage was about 15,000 kilometers. Vehicles can meet the bus lines. In normal operation, the LCK6210GT equipped with a manual transmission has an average fuel saving rate of about 4 liters per 100 km. Due to different lines, the overall fuel saving rate is about 10%.
After listening to Li Daoxin’s introduction, Liu Junlan, Changchun’s Minister of Public Transport Technology, was quite interested in: “If we can really achieve a fuel saving rate of 10%, the benefits will be considerable. After going back to Changchun, I intend to learn more about the vehicles with the regional manager of Zhongtong Bus . Case."
Faced with fluctuations in crude oil prices, the cost control of public transport companies is now very serious. The fuel saving rate reaches 10%. For Tianjin buses, if each vehicle achieves this effect, it will save tens of millions of yuan in fuel costs in a year. Even if some public transport companies’ profits are not so obvious, it is no doubt that fuel costs now account for more than 1/3 of the total cost of the company.
Fully enter the domestic bus market
Energy conservation and environmental protection is the inevitable direction for the development of the bus industry in the future. In this direction, Zhongtong has been making every effort to create the image of an energy-saving and environmental leader. “New energy is a trend, and traditional fuel-saving is in the momentâ€, and the energy saving of existing models is undoubtedly more realistic and more urgent.
When Zhong Gong Bus General Manager Shi Honggong introduced, Zhongtong Bus has adopted “Two Handsâ€: One-handed study of new energy bus R&D, incorporating it into strategic planning, and continuously increasing investment; the other hand is focusing on traditional fuel-saving technology research and the traditional passenger car The operating costs have been reduced to a minimum, enabling Zhongtong Bus to create maximum benefits for its customers.
After two years of hard work, the LCK6120GT and LCK6103HG were formally launched this year. At the seminar, most of the heads of public transport companies expressed interest in the two products. It is understood that they are not only fuel-efficient, but also include a large amount of passengers.
According to Gao Xinchuan, Minister of Public Transport and Technical Equipment of Jinan, there are three highlights of the two models: the large rectangular passenger car chassis carries the body, the A-frame air spring rear suspension for large buses, and the compound front for large buses. suspension.
These three items are patented innovations of Zhongtong . The advantage is that under the premise of not significantly increasing the cost price, the vehicle trim quality is light, the comfort is high, the structure is simple, the space is expanded, and the passenger carrying capacity is increased. This also means that the vehicles increase passenger capacity while reducing fuel consumption, which leads to a significant drop in passenger fuel costs per person and increases the efficiency of the bus companies. This is another sense of savings.
Zhongtong has high hopes for these two models. Shi Honggong hopes to use these two models to enter more markets, not just to satisfy the success of the trial operation of Tianjin Public Transport. “As a symbol of this seminar, Zhongtong Bus blew a clarion call to fully enter the domestic bus market,†he said.
