Abstract

A torsion beam bush component comprises a tubular bush assembly with mounting support lugs and a limit ring at one end of the tubular bush assembly. The tubular bush assembly comprises an outer bush, an integrated axial inner bush and an integrated part integrally vulcanized by rubber materials. The integrated part is filled into an axial annular space between the outer bush and the integrated axial inner bush. The integrated axial inner bush is an integrated part comprising an inner bush and the supports lugs at two ends. The limit ring is flange plate with a threaded inner hole. During use, the tubular bush assembly is pressed to a torsion beam through interference fit, and the limit ring is integrally connected with the integrated axial inner bush mounted on the torsion beam in a threaded manner. A torsion beam suspension using the torsion beam bush component has improved assembling precision, overall performance and reliability. In addition, the torsion beam bush component is convenient to machine and mount and low in cost.
