Electromechanical Transmission

Abstract

The article is to propose an entirely new transmission scheme. At a common practice that transmission parameters in a car change the gear ratio and the torque by five or six times. Taking into account the engine speed change, the actual gear ratio change is by more than twenty times. The torque cannot change within these limits. On the contrary, when the engine rpm speed differs from the optimum one, the torque decreases. Losses at gear ratio alteration, especially at low gears, can reach ten percent of the power. These torque and ratio control parameters can be achieved by applying the transmission scheme described in this article. Her work is also documented in a patent RU2726378 (2020) and application PCT/RU2020/000322. The operation of a transmission of this design is an improved version of the transmission described in Khadeev (2017).
