Detachment tire of elastic side bearing

The utility model relates to a detachment tire of elastic side bearing which comprises a fixed tire and a movable tire that are positioned in a same horizontal surface. The movable tire can near and move relatively to the fixed tire on the horizontal surface and generate a certain horizontal pressure in the direction of the fixed tire. The amount of the certain horizontal pressure is calculated according to the elastic variation generated by the squeezing of the side bearing iron. The movable tire comprises a spacing mechanism. The utility model settles the technical problems of easy damage orside bearing iron or side bearing steel ring and low efficiency. Furthermore the detachment tire provided by the utility model has the advantages of small labor intensity, no damage to side bearing iron or side bearing steel ring, good detachment quality and high efficiency.
