Driving device for variable damping force of semi-active suspension

摘要

The present invention relates to a damping force variable device for a damping force control device that transmits a driving force accurately with a simple structure and makes a damping force unauthorized. Conventionally, there are disadvantages that are caused by an uneconomical surface according to a complicated structure, In the present invention, the rack 20 and the pinion 22 are connected to one end of the adjustment rod 12 so that the adjustment rod 12 makes linear reciprocation by the power of the motor 24, So that the damping force can be induced unrestrictedly, thereby enabling economical and efficient use by a simple structure.
