The invention discloses a 5-ton super-heavy load loader drive axle which comprises a wheel side assembly, a half shaft, an axle housing, a main transmission assembly, a supporting shaft and a brake, wherein the axle housing and the supporting shaft serve as a bearing component after being welded, the two sides support the wheel side assembly, the main transmission assembly is installed in the middle of the axle housing, and the two sides of the half shaft are connected with the wheel side assembly and the main transmission assembly. The brake is mounted on the axle housing; the modulus of a driving gear and a driven gear of the main transmission assembly is not changed, the number of the driving gear is 9, the number of the driven gear is 37, and the main transmission speed ratio is reduced from 5.286 to 4.11, so that the main transmission reduction ratio with high failure rate is reduced; the modulus of a wheel side gear of the wheel side assembly is 5, the number of planet gears is 4, the number of teeth of a sun gear is 15, the number of teeth of an inner gear ring is 69, the wheel side reduction ratio after optimization is increased to 5.6 from 4.4, so that the wheel side reduction ratio without faults is improved, and it is guaranteed that the total reduction ratio of the drive axle assembly after redistribution is kept equivalent to the original total reduction ratio. The drive axle is compact in structure, long in service life and reasonable in safety coefficient.
本发明公开了一种5吨超重载装载机驱动桥,它包括轮边总成、半轴、桥壳、主传动总成、支撑轴、制动器,所述桥壳和支撑轴焊接后作为承载部件,两边支撑轮边总成,桥壳中间安装主传动总成,半轴两边连接轮边总成和主传动总成,制动器安装在桥壳上;所述主传动总成的主动齿轮和被动齿轮模数不变,主动齿齿数9,被动齿齿数37,主传动速比由5.286降至4.11,以降低故障率高的主传动减速比;所述轮边总成的轮边齿轮模数5,行星轮的个数4个,太阳轮的齿数15,内齿圈的齿数69,优化后轮边减速比由4.4增加为5.6,以提高没有故障的轮边减速比,保证重新分配后驱动桥总成的总减速比与原有总减速比保持相当。本发明结构紧凑、使用寿命长、安全系数合理。
