自充气轮胎研制成功 日前,一种自充气轮胎由河南师范大学研制成功,并获得国家专利。 河南师范大学物理系应用物理研究所的科技人员研制的自充气轮胎是指汽车在运行时轮胎本身自动吸满空气的轮胎。其原理是:轮胎在向前滚动时利用其接触地面时所产生的轮胎变形,导致设计在轮胎中的一根橡胶管产生内外气压差而做功,将轮胎外空气不
The successful development of self-inflating tires Recently, a self-inflating tire was successfully developed by Henan Normal University and obtained national patent. The self-inflating tire developed by scientific and technical personnel of the Institute of Applied Physics of the Department of Physics of Henan Normal University refers to the tire that the car itself automatically sucks air when it is running. The principle is: when the tire is rolling forward, the tire deformation caused by its contact with the ground causes a rubber tube designed in the tire to generate an internal and external air pressure difference and work, and the air outside the tire is not
