东风EQ140A型汽车是我国载货车辆的主要车型之一,在交通运输战线上发挥着重要作用。它以功率大、车身高、油耗低、转向轻便、视线好、驾驶室座位舒适等优点,深受用户的好评。但由于有些用户在使用中,对主减速器润滑不当,使齿轮轮齿过早磨损,导致主减速器报废,造成了不应有的损失。 EQ140A型汽车的后桥主减速器,采用啮合平稳、噪音小、结构紧凑的双曲线齿轮传动。这种齿轮传动,主、被动齿轮的轴线不在同一平面内,而是采用具有偏移距的下偏置传动。由于主、被动齿轮轴线偏置,主动轮的 Dongfeng EQ140A-type car is one of the main models of China’s truck, in the transport front plays an important role. It is high power, high body, low fuel consumption, steering light, good sight, comfortable seat cab, etc., by the user’s praise. However, due to some users in use, improper lubrication of the main reducer, gear teeth premature wear, resulting in the final reducer, resulting in undue loss. EQ140A car rear axle main reducer, using meshing smooth, low noise, compact hyperbolic gear drive. This gear transmission, the main and driven gear axis is not in the same plane, but the use of bias with the next bias transmission. As the main, passive gear axis offset, the drive wheel
