A torsion beam assembly for supporting bush of torsion bar with have it

The utility model discloses a torsion beam assembly for supporting bush of torsion bar with have it, be equipped with on the bush be suitable for with torsion bar interference fit's mounting hole and with the opening of mounting hole intercommunication, the bush has the installation face that ends to torsion beam that is suitable for, the bush has the damping hole, the damping hole site in installation face with between the mounting hole. The utility model discloses a manufacturing cost for supporting the bush of torsion bar, hardness and rigidity are suitable, the elastic deformation scope is bigger, change assemble the torsion bar on, and bush and damping between torsion bar, the torsion beam cooperate the effect lower to the requirement of the installation accuracy of the straightness accuracy of torsion beam's shaping precision, torsion bar and torsion bar, is favorable to reducing the torsion beam assembly. 本实用新型公开了种用于支撑扭杆的衬套和具有其的扭转梁总成，所述衬套上设有适于与所述扭杆过盈配合的安装孔和与所述安装孔连通的开口，所述衬套具有适于止抵扭转梁的安装面，所述衬套具有阻尼孔，所述阻尼孔位
