The bush assembly of torsion beam type rear suspension in vehicle

摘要

PURPOSE: A bush assembly of a rear suspension by using a torsion beam is provided to improve lateral stability of a vehicle by decreasing the size and the thickness by decreasing the contact area of the bush, and to design conveniently without limit of layout by covering the rubber with a mounting pipe. CONSTITUTION: A bush assembly for combining a trailing arm with a vehicle body is composed of a bush combined by a hinge shaft(2) penetrating a support bracket(1). The bush has a rubber(5) covered with inner and outer pipes(3,4), a mounting pipe(6) including the staple-shaped section opened to contact and support with containing the rubber, and a stopper(7) combined with the support bracket by a fixing end to eliminate the gap from the pipe. Deformation is prevented and lateral stability is improved with increasing the contact area of the bush and the mounting pipe.
