The invention provides a steering differential driving device for dual-drive machinery. The steering differential driving device comprises a driving wheel, power equipment, a magnetorheological device, an electromagnetic power-off brake, a planetary gear mechanism, a power input shaft and a hollow shaft, the planetary gear mechanism comprises a planetary carrier, a gear ring, a center wheel and a plurality of planetary gears, the planetary carrier is connected to the planetary gears, the hollow shaft is fixedly connected to the gear ring through a fixing disc, the power equipment is in driving connection with the center wheel through the power input shaft, and the driving wheel is connected to the planetary carrier. According to the steering differential driving device, the magnetorheological device and the electromagnetic power-off brake are installed on the hollow shaft in a rotating mode, and then the rotating speed of the driving wheel can be adjusted by controlling the rotating speed of the planetary gear mechanism. Compared with dual-drive machinery without differential steering in the front-back direction, the steering differential driving device has the advantages that power circulation of steering is eliminated, operation is more stable, efficiency is higher, and high-speed operation of the dual-drive machinery is better facilitated.

    本发明提供一种用于双驱动机械的转向差速驱动装置,包括驱动轮、动力设备、磁流变装置、电磁失电制动器、行星齿轮机构、动力输入轴和空心轴;行星齿轮机构包括行星架、齿圈、中心轮以及若干个行星轮,行星架与行星轮连接,空心轴通过固定盘与齿圈固定连接;动力设备通过动力输入轴与中心轮驱动连接,驱动轮与行星架连接;磁流变装置、电磁失电制动器可转动安装在空心轴上,可通过控制行星齿轮机构的转动速度,进而调节驱动轮的转动速度。本发明相较于前后无差速转向的双驱动机械,消除了转向的功率循环,运行更为平稳,效率更高,更加有利于双驱动类机械的高速作业。
