[0002] Circular rubber suspension is usually used in longitudinal vehicle models. The shell of this suspension structure is mainly composed of left and right mounting brackets, a circular frame and a bottom plate, and all parts are stamped. Among them, the left and right mounting brackets and the circular frame are welded after being positioned by tooling, and the bottom plate and the main spring are vulcanized together and put in from the bottom of the circular frame.
