Abstract
The utility model relates to a steel plate spring rubber bushing and a suspension system with the same. The steel plate spring rubber bushing is provided with a bushing inner hole, a bushing upper end face and a bushing lower end face, the bushing inner hole is provided with inner hole friction grains and the bushing upper end face is provided with end face friction grains. The utility model further provides the suspension system with the steel plate spring rubber bushing. The steel plate spring rubber bushing has the advantages that the bushing inner hole is provided with the inner hole friction grains, and the bushing upper end face is provided with the end face friction grains; because of existence of the inner hole friction grains and the end face friction grains, the friction coefficient of the bushing inner hole and the bushing upper end face is increased, frictional force increases, and the probability of the situation that the steel plate spring rubber bushing relatively moves relative to an installation face or a fixed surface of the steel plate spring rubber bushing is reduced; meanwhile, the contact area between the bushing inner hole and parts assembled around the bushing inner hole and the contact area between the bushing inner end face and the parts assembled around the bushing inner end face are reduced, and generation of abnormal sound caused by friction is reduced fundamentally.
