The invention discloses a drive axle system for a loader. The system comprises: a front axle, a front transmission shaft, a supporting seat assembly, a middle transmission shaft, a gearbox, a rear transmission shaft and a rear axle which are connected in sequence, wherein the front axle is a steering drive axle and comprises a drive axle and hubs on the two sides; a front axle locking oil cylinder and a front axle steering oil cylinder, wherein one ends of the two oil cylinders are connected with the drive axle, and the other ends are connected with the corresponding hubs; a front frame and a rear frame, wherein a steering oil cylinder is hinged between the front frame and the rear frame, and the front frame and the rear frame are connected through a hinge pin; and a hinged locking oil cylinder which is arranged on the front frame or the rear frame. When the loader operates in a high-speed mode, the front frame and the rear frame are locked into a whole in cooperation with the hinge pin; and the front axle and the rear axle are respectively hinged with the front frame and the rear frame through a push rod and a suspension oil cylinder. The loader can have a high speed mode and a low speed mode, the highest speed of the loader in the low speed mode is equal to that of a common loader, the speed of the loader in the high speed mode can be larger than 80 km/h, and therefore specific requirements of some users are met.

    本发明公开了一种装载机用驱动桥系统,包括顺次相连的前桥、前传动轴、支撑座组件、中传动轴、变速箱、后传动轴和后桥;前桥为转向驱动桥,包括驱动桥和两侧的轮毂;前桥锁止油缸和前桥转向油缸,二者的一端与驱动桥相连,另一端与对应的轮毂相连;前车架和后车架,二者之间铰接有转向油缸,且二者通过铰接销相连;铰接锁止油缸,设于前车架或后车架上,当装载机运行在高速模式时,配合铰接销将前车架和后车架锁死成为一体;前桥、后桥还分别通过推杆和悬挂油缸与前车架、后车架铰接。本发明可使装载机具有高、低两种车速模式,低速模式时最高车速同普通装载机,高速模式时车速可大于80km/h,从而满足某些用户的特定需求。
