The invention discloses an accelerator brake gear. The accelerator brake gear comprises a power-losing type electromagnet, an air spring, a first oil cylinder, a positioning plate, a second oil cylinder and a resistance strain gage. A piston rod of the air spring can penetrate through the two sides of the power-losing type electromagnet. The first oil cylinder is fixed to the other side of the power-losing type electromagnet through one or more positioning rods. The positioning plate and the positioning rods constitute a moving pair. One side of the positioning plate is connected with a piston rod of the first oil cylinder, and the other side of the positioning plate is connected with the piston rod of the air spring. A cylinder tube of the second oil cylinder is connected to a brake rod in a rotary mode, and a piston rod of the second oil cylinder is connected with a brake gear body. The end, away from the corresponding piston rod, of a cylinder tube of the first oil cylinder is communicated with the end, away from the corresponding piston rod, of the cylinder tube of the second oil cylinder through an oil pipe. The resistance strain gage is sequentially and electrically connected with an AD converter, a single-chip microcomputer and the power-losing type electromagnet. A limiting pillar is arranged under an accelerator pedal, and a limiting plate is arranged on a vehicle body. The accelerator brake gear has the beneficial effect that the technical defect of the prior art that a driver often treads down an accelerator by mistake during braking to cause traffic accidents is overcome.
