The rear axle assembly comprises a rear axle assembly body, a differential gear package and an assistor are installed in the middle of the rear axle assembly body, the rear axle assembly body is connected with a power shaft, and chain wheels are installed on output shafts at the two ends of the differential gear package. A chain wheel on an iron wheel shaft running on a rail and a chain wheel on a wheel half shaft running on the ground are respectively driven to rotate, a differential lock is installed on one output shaft and used when the iron wheel running on the rail rotates, an iron wheel is installed on the rear axle assembly, and a gear is installed on the iron wheel and used for driving the wheel to rotate. The iron wheel and the gear are in contact with a special track installed in the field or without a road, a rack is arranged on the special track to clamp the gear so as to prevent slipping, and a disc brake is installed on an iron wheel driving shaft and used during speed reduction or stopping; a disc brake is installed on a wheel half shaft, a rail clamping auxiliary wheel is installed at the other end of the wheel half shaft and located below the iron wheel, and the iron wheel and the rail clamping auxiliary wheel clamp the special rail between the iron wheel and the rail clamping auxiliary wheel to prevent the rail-road dual-purpose vehicle from deflecting.
