Bearing bush e.g. wishbone bearing bush of motor vehicle, has bearing bush main structure whose hardness value is varied with respect to hardness value of wishbone, due to energization state

摘要

The motor vehicle has a transverse control arm that is designed in conjunction with a strut tower that is accelerated or braked to generate horizontal force. The bearing bush main structure is loaded with current under driving condition. The hardness value of the bearing bush main structure is varied with respect to the hardness value of the wishbone due to energization state. A base (2) is surrounded by a metal or plastic casing (3). The magneto-rheological substance (6) is provided with magneto-rheological liquid and magneto-rheological elastomer (MRE).
