解放越野车的中、后桥采用平衡悬挂结构(图1)。中、后桥的驱动力是通过拉臂和反作用杆传送到车架,而使气车行驶。从图1看出,后桥上臂和中桥上臂的力臂最大。据初步计算,后桥上臂最大作用力为3.5吨,而且它的负荷受道路条件影响而经常变化,反作用拉臂容易脱焊。针对这个问题进行了工艺改进,初步解决了拉臂的脱焊问题。

Liberation off-road vehicles in the bridge after the balance suspension structure (Figure 1). The driving force of the middle and rear axles is transmitted to the frame through the pull arm and the reaction rod, so that the car can travel. As can be seen from Figure 1, the arm of the rear axle and the upper arm of the middle bridge have the largest force arm. According to preliminary calculations, the maximum force of the rear axle upper arm 3.5 tons, and its load by the road conditions often change, the reaction arm pull off easily. Aiming at this problem, the process improvement was made and the problem of desoldering of the pull arm was initially solved.
