我们浙江生产建设兵团二师五团有一辆美式《顺风牌》小轿车改装的小货车,这辆小货车自改装后曾多次发生后桥半轴断裂,飞出车轮,造成事故。经过多次研究,找出了断轴的主要原因是该车后桥结构是老式“半浮”结构,半轴既受负荷,又受扭力,同时装配保养困难,再加上行驶道路起伏不平,有时负荷量偏高,以致造成后半轴的断裂。我们抓住这一主要矛盾进行改装。如附图十一(甲)是改装前,图十一(乙)是改装后的情况。经过改装,在 Our Zhejiang Production and Construction Corps Second Division five regiments have an American “Shunfeng” coupe modified pickup truck, which has repeatedly after the modification of the rear axle axles rupture, fly out of the wheel, causing an accident. After many studies, the main reason for finding the broken shaft is that the rear axle structure of the vehicle is an old-fashioned “half floating” structure. The axle is not only subjected to loads and torsional forces but also difficult to assemble and maintain. Coupled with the undulating roadways, sometimes High load, resulting in the rear axle fracture. We seize this major contradiction to be modified. As shown in Figure 11 (A) is modified before, Figure XI (B) is modified after the situation. After modification, in
