The invention belongs to the technical field of electric driving equipment, and discloses a high-efficiency heavy-load rear axle of an electrically-driven crawler. The high-efficiency heavy-load rearaxle comprises driving devices which are symmetrically arranged, each driving device comprises a direct-current motor and a speed reducer matched with the direct-current motor; a power output disc inthe speed reducer is connected with the power half shaft through a half shaft spline; the symmetrically arranged power half shafts are connected through a drive axle connecting part; the symmetrical speed reducers are connected through a drive axle connecting part to form an integrated structure; the drive axle connecting part is supported on a longitudinal beam in the middle of the chassis through a connecting part fixing piece. The power output end of the power half shaft penetrates through a drive axle tube and then is connected with a disc brake disc; the disc brake disc and a crawler beltdriving disc synchronously move under the action of friction force, power is output to the crawler belt driving disc through the power half shaft, the crawler belt driving disc drives a crawler beltto operate, the half shafts and the speed reducers are matched more tightly, meanwhile, a bridge type stable structure is formed, and the probability that the speed reducer is damaged and the half shaft is bent and broken is reduced.
本发明属于电力驱动设备技术领域,具体技术方案为:电驱履带车高效大载重后桥,包括对称布置的驱动装置,驱动装置包括直流电动机和与直流电动机相配合的减速机,减速机内部的动力输出盘与动力半轴之间通过半轴花键相连,对称布置的动力半轴通过驱动桥连接件相连,对称的减速机通过驱动桥连接件连接并形成一个整体结构,驱动桥连接件通过连接件固定片支撑在底盘中部纵梁上,动力半轴的动力输出端穿过驱动桥管后与碟刹盘相连,碟刹盘与履带驱动盘在摩擦力的作用下同步运动,动力通过动力半轴输出至履带驱动盘,履带驱动盘带动履带运转,半轴和减速机配合的更紧密,同时形成了桥式稳定结构,降低了减速机损坏和半轴弯曲、断裂的概率。
