载重汽车在行驶中常出现半轴折断的故障。如出现此故障,只有将半轴断头取出后才能换上新的半轴。若半轴自外端(轮毂端)折断,只要将另一根半轴拆下,换用长的木棒或铁棒插入半轴套管中,把断半轴捅出即可。若半轴从里端(差速器端)折断,要取出断半轴就较难了。因为一般情况下断头只有10cm左右的长度,且存留在差速器中的半轴齿的花键内;而差速器壳到半轴套管的内端头之间有一个15cm以上的空隙(该空隙因车型而异,大小不等),半轴断头必须通过这个空隙,才能从半轴套管内取出。要是也照上述方法用木棒或铁棒去捅断头半轴,该断头势必要掉入空隙中(即后桥壳内),或卡在差速器壳与半轴套管之间,这样就得花大功夫把主减速器总成从后桥壳上拆下,才能取出断头半轴。显然,这种方法是不可取的。
Semi-axle breakdowns often occur in trucks when driving. In the event of this failure, only the semi-shaft decapitated removed after the new half-shaft. If the semi-shaft from the outer end (hub end) broken, as long as the other half-shaft removed, with a long wooden stick or iron rod into the half-shaft sleeve, the broken half shaft poke out. If the half-shaft is broken from the inner end (differential end), it is harder to remove the half-shaft. Because the general case of decapitated length of only about 10cm, and remain in the differential half-shaft tooth spline; and differential housing to the half-shaft sleeve between the inner end of a 15cm gap (The gap varies by vehicle type, size range), the shaft must be broken through this gap in order to be removed from the shaft sleeve. If you also use the above method to use a wooden stick or iron bar to stab broken head and axle, the broken head is bound to fall into the gap (ie, rear axle housing), or stuck in the differential housing and half-shaft sleeve, This will take a big effort to remove the main reducer assembly from the rear axle housing to remove the broken half shaft. Obviously, this method is not desirable.
