Diseño computacional de engranajes magnéticos para una transmisión ECVT en los vehículos híbridos

Abstract

In the present investigation the problems of planetary gears in hybrid vehicles are addressed, mainly in efficiency; because it is diminished by sound, vibration, heat and the design of the tooth profile. Therefore, the main objective is to computationally design magnetic gears as an alternative to planetary gears. To achieve this purpose, it is necessary to understand the operation of the electronic-type continuously variable transmission system (e-CVT) since, in its structure, it uses two planetary gears whose main function is to transmit the power of the engines, both electrical and internal combustion, towards the wheels. The main motor of the e-CVT transmission system will be analyzed and chosen in order to design a magnetic gear capable of replacing and surpassing the planetary gear used. For this, the magnetic torque generated by the permanent magnets will be analyzed; in order to obtain a sizing that has the capacity to transmit the necessary power to move a hybrid vehicle model sedan. Likewise, the efficiency of magnetic gears as well as the magnetic saturation of permanent magnets will be analyzed. As a result, a coaxial magnetic gear was proposed that has the capacity to generate 249.75 Nm at an efficiency of 98.7% and with a magnetic saturation range of 0.5 - 4 T, surpassing planetary gears in efficiency and being viable for installation. in the e-CVT transmission system.
