Can the semi-trailer be widened to make a single tire oil efficient?
What is a single tire Trailer?The single tire trailer, as the name suggests, has only one large tire on each side, and only six of the trailer tyres are in the car, while the regular and double tires are twelve. Single trailers now use in Europe and has been very widely, but in the current domestic use is still relatively small, but with the application of our country new technology and energy saving and emission reduction, I think in the near future large trailer tire will become a new trend of domestic logistics industry.
What are the advantages of a single tire Trailer compared with an ordinary one?Advantage one: light weight. Single 425/65R22.5 (including rim) weight 153Kg/ for each twin 12R22.5 (including rim) weight 224Kg/ for each tire and rim is twin and singleton is 224kgx6=1344kg, 153kgx6=918kg, single birth weight 426kg.
Advantage two: small friction. Relative to the theoretical reduction in fuel consumption, we see the following figure:Bridgestone M729 tires, a width is 26cm, the two add up to 52cmSingle tire size width 32cmWe saw a single tire width of only 32cm, less than two regular twin tire contact area of 20cm. What is this concept, if after the bridge together?Advantage three: stability is strong. Since the single car is longer rear axle, so the wheelbase is relatively wide, relative driving and cornering stability is better than the ordinary twin.The single frame bridge model is 2050, and the common twin rear axle type is 1840.
