"Green tire" technology research and development hot promotion difficult
On June 15, the "2015 Global Tire Technology Forum" sponsored by the China Rubber Industry Association opened in Dalian, Liaoning Province. The forum was the first event of the “6·15 China Green Tire Safety Week†and was actively participated by large domestic tire manufacturers, raw material suppliers and tire distributors. The promotion of green tires and the research of smart tires have become the focus of this forum discussion. 　　 Fire Truck also known as Fire Fighting Truck,Fire Emergency Truck,Water Fire Truck, Water Foam Fire Firhting Truck.

The "green" goal of the entire industry chain is that "green tires are not the concept of a single product, but rather the requirements of the entire industry chain." Xu Wenying, vice chairman and secretary-general of the China Rubber Industry Association, said in an interview with reporters. The so-called green tires are radial tires that are energy-saving, environmentally-friendly, and safe. They have low rolling resistance, low fuel consumption, excellent handling stability, shorter braking distances, better wear resistance, and can be rebuilt many times. Dynamic product features. Green tire raw materials and the entire production process practice the concept of green manufacturing, application process advocates green use.
In March 2014, China Rubber Industry Association promulgated the self-regulatory standard "green tire technical specifications", laid the foundation for the promotion of China's green tires and China's tire grading and labeling, and promote China's tire technology regulations gradually with the international standards.
In recent years, mainstream suppliers at all levels of the tire industry have increased investment in green tire technology research and development. Luo Xiaowen, Global Technical Innovation Director of Belcat Management (Shanghai) Co., Ltd., said that to manufacture light-weight and low-roll resistance tires, higher-strength steel wire is needed to apply fewer cords while maintaining the same cord strength. The diameter of the steel wire monofilament also improves the comfort of the tire. "The tire performance contributes more than 50% to the performance of the vehicle. The tire rolling resistance accounts for 18%~30% of the total vehicle resistance. The quality of the tire determines the performance of the vehicle to a large extent." Zhang Hongbin, director of the chassis department department of the Group Automotive Engineering Research Institute, said, “The development of green tires is still based on safety performance, and we must fully consider the requirements for load capacity, braking capacity, durability, resistance to damage, resistance to detachment, and high-speed capability. ."
For the freight market, Yang Dongbo, Minister of Energy Saving and Emission Reduction Research at the Highway Research Institute of the Ministry of Transport of China, believes that more than 50% of the tyres in China's freight tire market have not passed 3C certification, and the overall market tire radialization rate is about 85% to 90%. . The freight industry has become the largest energy consumer in the entire transportation industry. Tire use costs account for approximately 6% of the freight cost of the entire truck. Tire rolling resistance accounts for 13.5% of vehicle energy consumption. If the tire rolling resistance coefficient is reduced by 15%. The fuel economy can be increased by 3%. Green tires have a lot of room for development in the freight market.
Where is the root of "promotion difficult"
The promotion of green tires is generally difficult in many ways. A number of tire industry experts have defined "understanding of concepts" as the primary factor in the difficulty of green tires. Qian Ruiqi, chief engineer of Shuangqin Group Co., Ltd., told reporters: “Many domestic consumers and companies have a serious lack of awareness of green tires. Green tires are still a fashion concept, and they are still widely accepted by consumers. a period of time."
Yang Dongbo said that green tires have been piloted in a few transportation companies in China and achieved certain results. However, from the perspective of the entire freight industry, green tires are still in the stage of product introduction. In fact, green tires have been used in a large number of applications in the new energy vehicle market that embodies energy conservation and emission reduction performance. In contrast, there are currently few green tire products for the domestic freight industry, and the related product certification system is not perfect, and the auto companies' autonomy in selecting green tires is not strong. In general, the unit price of green tires is 10%~30% higher than that of traditional tires. The increase in the cost of four-wheeled passenger vehicles with green tires is still within an acceptable range, and the focus is on economic benefits. Commercial vehicles can hardly accept this increase in cost. In addition, due to different vehicle performance and usage status, the fuel savings brought by green tires are also different, generally only 1% to 5%. Therefore, many companies have different effects on the practical application of green tires.
Qian Ruiqi, chief engineer of Shuangqin Group Co., Ltd., believes that the important reason for the difficulty in promoting green tires is that China's tire industry has relatively weak supporting capabilities and the overall service level is also low. Foreign excellent tire companies can not only produce high-performance products, but also can provide overall vehicle solutions for tire applications and testing. This is also a huge challenge faced by the tire industry manufacturers and testing companies in China.
"Green" Developing Smart Tires
Smart tires are another focus of this forum. The high-tech smart tire video displayed by Etienne Besnoin, project leader of the Goodyear Global Innovation Center at the forum, attracted great attention from field experts. Etienne Besnoin said that smart and green environmental protection are the two major trends in the development of the global tire industry. It is reported that Goodyear's smart tire has multiple inflatable chambers, which can inflate and deflate the tires according to the conditions of the road surface and the needs of the driver, adjust the handling performance of the vehicle, and in particular, improve the turning stability of the vehicle and achieve these functions. Benefit from smaller, more advanced electronic sensors placed in the tires.
Yang Xiaoguang, a researcher at the Academia Sinica of Baosteel Group, introduced that smart tires generally refer to tire systems that have sensors installed to monitor tire stress conditions and road conditions, and in turn help improve vehicle performance. Tires with tire pressure and tire temperature monitoring are now commonly used as primary smart tires, tires that can monitor tire forces and road conditions are mid-level smart tires, and future smart smart tires can realize tires that are subject to environmental adjustments. performance. The intelligent tire system is integrated with the vehicle's CAN bus and based on surface acoustic wave sensors, ultrasonic sensors, and optical sensors, seven types of sensors accurately measure the degree of deformation of the rolling tire in real time and perform a large number of data operations and analysis. At present, middle-to-advanced smart tires are still in a large number of experimental analysis stages, and the real application of tires depends on the appearance of tire materials and new design structures. In the future, the application of such advanced smart tires will also be a key component of driverless cars and an important step in supporting the development of intelligent transportation in the era of big data.
