Limited-slip differential (LSD) is a kind of differential system which permits output shafts to rotate at different speeds but the maximum speed difference between shafts is limited. In automotive applications, limited-slip differentials are occasionally implemented in place of traditional differential systems. This paper introduces a detailed design of magnetorheologically automotive LSD to improve torque distribution which influences traction and maneuverability. The designed automotive LSD is submerged in magnetorheological fluid (MRF) which allows controlling the locking torque efficiently and then enhancing the vehicle traction characteristics. The yield stress of MRF depends on the magnetic field applied by the electromagnet by varying electric current. To assess the designed automotive LSD, an experimental test-rig contains some rotating clutches immersed in MRF associated with an electromagnet coil was manufactured. Experimental tests are achieved with and without magnetic field to change the MRF viscosity to measure the mechanical force on friction clutches. The controllable yield stress generates friction force on the rotating clutches surfaces to transmit torque. The complete theoretical calculations of the automotive LSD is done and applied in the manufacture process. The transmitted torque is assessed to judge the efficiency of the designed automotive LSD. The experimental results reflect that the designed automotive LSD can offer a highly acceptable level of automotive traction.
