The invention relates to self-acceleration equipment composed of a two-degree-of-freedom torque amplifier. The two-degree-of-freedom torque amplifier is a rail-type cam mechanism, any speed ratio canbe achieved between the input end and the output end of the two-degree-of-freedom torque amplifier, the force transmission through rigid collision between a roller and a rail is achieved between the input end and the output end, and the rotating speed of the output end is lower so that the amplified torque can be output; a power source and the equipment are installed together to form a whole, theoutput destination of the output end is the equipment itself, under the situation, the load torque formed by the input end under driving of the power source and the amplified torque output by the output end can act on the equipment at the same time, and an unbalanced state of the torque is presented; the unbalanced state of the torque can be further converted into the internal unbalanced stress ofthe equipment so that the equipment can independently generate the acceleration; and the internal unbalanced stress is guided to the equipment shell to form linear self-acceleration equipment, and isguided to the power source to form circumferential self-acceleration equipment.
