Abstract
A secondary brake for commercial vehicles using Magnetorheological (MR) fluid may include a rotor coupled to a transmission output shaft to be rotated together, a stator configured to be disposed between the rotor and a body of a transmission and having a cavity into which the MR fluid is filled and a portion of the rotor is received, and a stator coil provided in a portion of the stator and applying a magnetic field to the MR fluid so that braking torque is generated due to a shear resistance characteristic of the MR fluid.
