ABSTRACT:
A top end retainer for an air spring sleeve in an automotive strut suspension system includes an elliptic clamping flange having a perimeter equal to the circumference of the top end of the air spring sleeve so that the sleeve fits over the clamping flange without stretching. A bushing aperture in a center web attached to the clamping sleeve is offset to an end of the flange. A piston rod of the strut is received in the bushing aperture through an elastomeric bushing and the center web is connected to the sprung mass for rotation so that the strut and air spring are rotatable about a steering axis. The geometric center of the elliptic flange is further offset from the longitudinal axis of the strut than would be the case with a circular flange having a diameter equal to the diameter of the top end of the air spring sleeve so that the top end retainer according to this invention contributes to optimization of the inclination of the line along which the air spring resultant force is directed.
