近年来,在我国大量购进的进口高档轿车中,有很多都装有自动变速器。对于自动变速器的正确操作,我国的驾驶员还很陌生。一本有关自动变速器维修的书中提到:“爬坡时不要长时间使用‘L’、‘2’档位,否则自动变速器会因过热而损坏;因此为防止这种情况发生也应使用‘D’档位。”笔者认为实际情况恰恰与之相反,这句话存在错误。在此,我们对装用自动变速器的汽车在较长坡路上行驶的工作情况作个分析。
In recent years, China imported a large number of imported luxury cars, many are equipped with automatic transmission. For the correct operation of automatic transmission, the driver of our country is still very strange. A book on automatic gearbox repair mentions: “Do not use the ’L’, ’2’ gear for a long time on a hill, otherwise the automatic transmission will be overheated and damaged; therefore, to prevent this from happening, use ’ D ’stalls. ”I think the actual situation is exactly the opposite, this sentence is wrong. Here, we analyze the operation of a vehicle equipped with an automatic transmission on a long slope.
