装载机等四轮驱动车辆行驶时,容易出现俯仰与前后水平方向耦合振动。同时由于轮胎的动特性使前轮半轴扭矩不断增加,后车轮半轴扭矩不断减少。由于扭矩的不断积累将产生功率循环。
Loaders and other four-wheel drive vehicles, prone to pitch and horizontal coupling vibration before and after. At the same time as the dynamic characteristics of the tire front axle torque to increase, the rear wheel axle torque continues to decrease. Due to the continuous accumulation of torque will produce power cycle.
