Eliminate torsion bar system noise's structure

The utility model provides an eliminate torsion bar system noise's structure, includes the supporting seat, supports ball pivot and torsion bar shaft, and fulcrum ball hinged to puts in the supportingseat, and torsion bar shaft passes the support ball pivot, wherein support after the ball pivot precommpression and between supporting seat interference fit, torsion bar shaft scribbles the wear -resistant coating that coefficient of friction is low with supporting ball pivot complex skin, supports and is equipped with small clearance between wearing layer and the torsion bar shaft of ball pivot.Wear resistant self -lubricating friction is vice to come the friction between reduction support ball pivot and the torsion bar shaft, the impulsive noise that produces through the upper and lower home range who reduces torsion bar shaft in order to reduce the coefficient of friction who supports between ball pivot and the torsion bar shaft when avoiding moving through adopting. The utility modeldiscloses the noise of tor
