The invention discloses a variable-speed torque transmission mechanism capable of achieving power gear shifting, and belongs to the technical field of engineering vehicle transmissions, the variable-speed torque transmission mechanism comprises a shaft, a gear, a gear shifting clutch, a planet row and a shell, the planet row is adopted to participate in power transmission, the bearing capacity is high, and compared with a fixed-shaft gear, the variable-speed torque transmission mechanism is smaller in size and lighter in mass; the planet row is arranged at the rearmost end of a transmission path, a large single-stage speed ratio is designed, the large first-gear speed ratio is achieved, the speed ratio of a fixed shaft gear pair in front of the transmission path is reduced, the transmission torque is smaller, the size is smaller, the small gear is easier to manufacture and longer in service life, and the bearing capacity and reliability of the whole mechanism are improved. 本发明公开了一种可实现动力换挡的变速传扭机构，属于工程车辆变速器技术领域
