Shandong Yokohama rubber industrial Co., Ltd. Yokohama high-profile tires in Europe, has been BENTLEY, PORSCHE , AUDI, MERCEDES AMG high-performance tires as representatives, so that Yokohama rubber big parade march Frankfurt Motor show.
at the current Yokohama tires reputation in Europe, but is listed as a high-performance tires representatives , because many high-performance cars are ADVAN series of products, from BENTLEY , PORSCHE, AUDI latest partner to MERCEDES AMG, ADVAN will be considered sufficient to enhance the handling, performance, safety, fun was the best choice. Of course, in addition to cooperation in commercial vehicles, Yokohama Rubber more from 2006 to play in 2009, the exclusive sponsor FIA certified wtcc events, visible technical force Yokohama Rubber has been affirmed by the FIA.
with reduced air resistance in the preferred design techniques developed Hallmark reducing air resistance of the vehicle traveling tire design. As a technique to reduce the rolling resistance of tires new technologies that can improve airflow around the vehicle with the tire of the flow, so as to achieve the effect of reducing fuel consumption and environmental protection.
When the vehicle is running, the air stream formed around the tire irregular. Wherein the portion of the air flow to the side of the vehicle, driving the air resistance increased. In order to understandThis phenomenon depends, in 2010 developed Yokohama Rubber vehicle tire inspection technology surrounding airflow under simulated driving conditions (rolling tire in normal running), and application of the technology to the vehicle, together with the wind tunnel test for research and development.
※ artificial wind tunnel test is a test stream small, thereby reproducing the flow stream under real conditions, and observed, the test is passed.
This, by the wind tunnel test and simulation confirmed the reduction of the air resistance of the vehicle tire design. And application of this technology to the specific practical embodiment, the inner side of the tire so that the pattern of protrusions designed fin (fin-like tires). The use of fin-shaped design of the tire compared with ordinary tires, the tire itself although air resistance is increased, but the overall body look significantly reduce air resistance. Which also confirmed the fin to cause rotation of the tire when the air flow spiral rotation direction, causes a change in pressure around the tire, thereby producing a force pushing the vehicle forward, thereby reducing air resistance. In the future, we must also strengthen the evaluation of the actual vehicle outside the Relationship between the tire and the shape of the air flow, not only in pursuit of the goal tire performance, but also to promote the “reduce the air resistance of the vehicle’s tire production.” Do a published (closing December 20, 2012) on the
The technology at the National Olympics Memorial Youth Integrated Center of Japan (in Tokyo) organized the “26th Symposium numerical fluid dynamics.” And plans to be presented at the meeting in Cologne, Germany · February 5, 2013 “TireTechnologyExpo2013” (2013 Tire Technology Expo).
