Research and Prospect of Automobile Magneto-rheological Fluid Dual Clutch Transmission

Abstract

Abstract. The magneto-rheological fluid Dual Clutch Transmission (MDCT for short) adopts the magneto-rheological (MR for short) effect of magneto-rheological fluid (MRF for short) and the working characters of Dual-Clutch Transmission (DCT for short), and combines the characteristics with long service life, no wear, simple structure, accurate control of MR effect with the principles of DCT technology, it will be a new-style and high-efficiency automatic transmission. This paper elaborates the character, application and the present research of MRF and the traditional mechanistic DCT technology respectively, and put forwards the application prospects of the MRDCT in the future of the automobile automatic transmission.

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

“…Based on the magneto-rheological effect of MRF and work principle of the DCT, designed MRDCT. This new type of DCT has simple structure, small abrasion, good controllability, and response rapidly [8]. The gear box in the two transmissions is the same.…”

A novel magneto-rheological fluid dual-clutch design for two-speed transmission of electric vehicles

“…In this study, a new type of powertrain with MRF dualclutch (MRFDC) of EVs is proposed by combining DCT and MRF clutch [31]. The main contribution of this paper is to develop a new type of MRFDC that can be applied in EVs with two-speed transmissions.…”

Design of Automotive Magneto-rheological Fluid Dual-clutch

“…In this paper, we designed a magneto-rheological fluid dual clutch (MRDC), which could fulfill the requirement of the torque transmission for the medium and small displacement vehicles, to replace the traditional friction dual clutch [7]. Only by changing the current in the coil, the separation and combination of the clutch is realized.…”
