有一金杯客车,在低速时变速器运转正常,而在高速时发出有节奏的响声。 故障判断 (1)变速器齿轮磨损过度;(2)变速器轴泵松旷;(3)变速器第一轴与曲轴不同轴。 故障检查 将变速器分解逐步检查,发现第一轴稍微松旷但并不严重,各齿轮与轴承均正常,无过度磨损现象。更换第一轴后试车,高速时 There is a Gold Cup bus, which operates normally at low speeds and gives a rhythmic sound at high speeds. Failure to determine (1) Transmission gear wear too much; (2) Transmission shaft pump Song Kuang; (3) The transmission of the first axis and the crankshaft is not coaxial. Troubleshooting Check the transmission decomposition step by step and found that the first axis slightly loose but not serious, the gear and bearing are normal, no excessive wear and tear. After replacing the first axis test, high-speed
