斯堪尼亚LT—110汽车,里程超过15万公里之后,主变速箱发生脱档现象较为频繁。本文从使用角度谈谈有关问题。该车主变速箱设有结构相同的三套锁销式惯性同步器(其结构如图1),并在花键毅外花键齿上采取了防脱档工艺措施(如图2所示的“△”)。这三套同步器分別用在四、五档;二、三档;一、倒档之间,倒档同步器未装摩擦锥盘。 Scania LT-110 cars, more than 150,000 km mileage, the main gear shift occurs more frequently. This article from the perspective of the use of talk about the issue. The owner of the gearbox with the same structure of three sets of lock-type inertial synchronizer (its structure shown in Figure 1), spline and spur gear spline adopted anti-off-scale technology measures (as shown in Figure 2 “ △ ”). The three sets of synchronizers were used in the fourth and fifth gear; second and third gear; one, between the reverse gear, the reverse gear synchronizer is not equipped with friction cone.
