Abstract

The utility model provides a damping and noise reduction system and an automobile. The damping and noise reduction system comprises a tray bearing a spiral spring, and an elastic rubber sleeve arranged at the lower end of the spiral spring in a sleeved mode. The spiral spring is elastically connected with the tray through the elastic rubber sleeve, wherein the lower end of the spiral spring is sleeved with the elastic rubber sleeve. According to the damping and noise reduction system and the automobile, the structure of the tray is changed through optimal design, a spiral spring limiting zinc plate is replaced by the elastic rubber sleeve which is arranged at the end of the spiral spring in the sleeved mode, and therefore the functions of damping and noise reduction are achieved and the cost and weight of the whole automobile are reduced to some extent.
