Research and Magnetic Field Simulation of Automotive Magneto-rheological Fluid Dual-clutch Transmission

Abstract

Based on the magneto-rheological effect of magneto-rheological fluid (MRF) and the work characters of dual-clutch transmission (DCT) put forward a new type of automobile transmission: magneto-rheological fluid dual clutch transmission (MRDCT). The MRDCT has simple structure, no wear, low energy consumption and good controllability. The work principle of magneto-rheological dual clutch (MRDC) is expounded and the torque calculation formulas are established. A finite element model of the MRDC is established in Ansoft to simulate the magnetic field distribution. The results show that the two clutches have no electromagnetic interference.
