Abstract

The utility model relates to a stiffness and damping united adjusting vibration-reducing device. An air spring with an additional air chamber serves as an elastic element, and a magnetorheological vibration damper serves as a damping element. The stiffness and damping united adjusting vibration-reducing device is characterized in that the air spring is connected with the additional air chamber through a positioning control valve, and input voltage of the positioning control valve is controlled to change opening of a throttling orifice between the air spring and the additional air chamber so as to achieve stiffness adjustability of the air spring. The magnetorheological vibration damper is in parallel connection with the air spring, and input current of an excitation coil in the magnetorheological vibration damper is controlled to change magnetorheological fluid viscosity so as to achieve damping adjustability of the magnetorheological vibration damper. According to the vibration-reducing device, united adjustment of stiffness and damping is achieved, stiffness and damping are matched in a coordinated mode, good vibration-reducing effect can be achieved, and adaptability of vehicles to running working conditions is improved.
