| Abstract: | A speed and torque expansion device was proposed for reciprocating piston internal combustion engine to increase the coefficient of torque reserve and the coefficient of speed reserve. Electro-mechanical hybrid transmission was adopted to change the engine output speed-torque curve and both coefficients were increased to more than 2. This paper introduced the composition of the device, the design principles, working process, output characteristics and measures to improve the efficiency of the device. The device can replace the torque converter used in tracked vehicles which have strict size and weight requirements for power transmission devices. |
