The invention discloses an electric full-suspension wheel set force-transfer pin disassembling device which comprises a base, two hollow oil cylinders, a movable beam and a fixed beam. A supporting base is arranged in the center of the base. The two sides of the base are symmetrically provided with two stand columns. The stand columns are fixedly provided with guide columns respectively. The two hollow oil cylinders are installed on the stand columns respectively. The guide columns penetrate through the hollow oil cylinders and are sleeved with the hollow oil cylinders. The two ends of the movable beam are connected with the hollow oil cylinders respectively. The guide columns penetrate through the movable beam and are movably connected with the movable beam. The movable beam is provided with an ejector rod. The two ends of the fixed beam are fixedly connected with the guide columns respectively. The fixed beam is provided with an ejection oil cylinder connected with a supporting piece. The supporting piece is provided with an outlet structure through which a force-transfer pin is allowed to penetrate. When the device is used for disassembling electric full-suspension wheel set force-transfer pins, operation is simple, the disassembly efficiency is high, and all the force-transfer pins on a wheel set can be disassembled through one-time hoisting.
