The invention provides a highway-railway conversion device and a highway-railway car with the highway-railway conversion device. The highway-railway conversion device comprises a railway walking frame, a highway-railway car body and a highway-railway car body. The railway walking frame comprises a base and a wheel pair. The mounting frame can be connected with a vehicle body of the rail-road vehicle; the two ends of the telescopic piece are connected with the mounting frame and the railway walking frame correspondingly. The telescopic piece can drive the railway walking frame to ascend and descend relative to the mounting frame. The railway walking frame further comprises a mandrel, a radial bearing and a thrust bearing, the axis of the mandrel is arranged in the vertical direction, the lower end of the telescopic piece is connected with the upper end of the mandrel, an inner ring of the radial bearing and an inner ring of the thrust bearing are both connected with the mandrel, and the radial bearing is located above the thrust bearing. An outer ring of the radial bearing and an outer ring of the thrust bearing are both connected with the base, the radial bearing and the thrust bearing are both spherical bearings, and the sphere center of the radial bearing coincides with the sphere center of the thrust bearing. Through the technical scheme provided by the invention, the problem that the car body of the rail-road car shakes in the railway running process in the prior art can be solved.
