ABSTRACT:
A bush assembly for vibration control, particularly adapted for use in supporting a suspension arm of an automobile suspension system, which includes an inner cylinder and an outer cylinder which is smaller in length than the inner cylinder. The outer cylinder coaxially encircles the inner cylinder and is radially spaced therefrom to define a cylindrical clearance space encircling the inner cylinder. A generally cylindrical impact absorbing member of elastic material is secured in the cylindrical space and has at least a pair of diametrically opposite recesses facing the inner peripheral surface of the outer cylinder. Each of the recesses has an arcuate transverse cross section and extends along the length of the outer cylinder. The impact absorbing member has a portion of rectangular longitudinal cross section interposed between each of its recesses and the inner cylinder and having a length substantially equal to that of the outer cylinder. The impact absorbing member has a pair of radially outwardly tapered portions of trapezoidal longitudinal cross section interposed circumferentially between the recesses, and having an inner axial length substantially equal to the length of the inner cylinder and an outer axial length smaller than the length of the outer cylinder.
