Active torque is applied to a magneto-rheological clutch through a motor rotor, a magnetic control flow channel is formed in the clutch, when a force output rod moves stably, current is applied to a magnetic part, the magnetic field intensity in the magnetic control flow channel is changed, the viscosity and shear strength of a magneto-rheological medium are changed, and the inertia capacity of the magneto-rheological active suspension is adjusted. The rotor disc and the magneto-rheological clutch rotor are relatively static with the magneto-rheological clutch stator, so that the adjustable torque of the motor is transmitted to the screw rod, the suspension inerter is increased, and the active torque transmitted between the motor rotor and the magneto-rheological clutch is increased; when the force output rod is subjected to high-speed impact, the magnetic field intensity in the magnetic control flow channel is changed by reducing the current of the magnetic part.
本发明公开了一种可调惯容的磁流变主动悬架,通过电机转子向磁流变离合器施加主动力矩,离合器内设置有磁控流道,当出力杆运动稳定时,通过对磁性部施加电流,改变磁控流道内的磁场强度,以改变磁流变介质的粘度和剪切强度,使转子盘和磁流变离合器转子与磁流变离合器定子之间相对静止,实现电机的可调力矩向丝杆的传递,使得悬架惯容增大,电机转子与磁流变离合器间所传递的主动力矩增大;当出力杆受到高速冲击时,通过对磁性部减小电流,改变磁控流道内的磁场强度。
