Wherein a deformation type pressure sensor 16 is arranged on the inner sleeve along the shaft near one end of the outer sleeve. When the whole support assembly 1 generates torsion deformation due to road surface jolting, the middle part of the connecting beam 14 is pressed and arched to press the first buffer piece 151 and the second buffer piece 152, the deformation pressure sensor 16 is pressed and deformed, and sends deformation signals to the controller 20, the controller 20 calculates the received pressure and sends out current with proper size according to the pressure, the polarity of a magnetic field generated by the inductance coil on the outer sleeve is repelled with the magnetic pole on the electromagnet on the inner sleeve due to the like polarity, and a force in the opposite direction can be generated, so that the stress of the first buffer piece 151 and the second buffer piece 152 is reduced, the arch of the middle part of the connecting beam 14 is reduced, and the deformation resistance of the support assembly 1 is improved.
