W4－60型轮式挖掘机动力传递方式是柴油机动力由离合器传给变速器，变速器以不同的挡位将动力传给上传动箱，再通过垂直传动轮传给下传动箱，下传动箱又通过前后传动轴将动力传给前后桥并带动车轮转动使挖掘机行走（图1）。本机具有诸多优点，但在实际修理中，经常会遇到同一问
W4-60 wheeled excavator power transmission mode is that the diesel engine power is transmitted from the clutch to the transmission, and the transmission transmits power to the upper gear box through different gears, and then passes through the vertical transmission wheel to the lower gear box, and the lower gear box passes through. Front and rear drive shafts transmit power to the front and rear axles and drive the wheels to move the excavator (Figure 1). This machine has many advantages, but in the actual repair, often encountered the same question
