The invention relates to the technical field of automobile suspension parts, in particular to a protection device of a plate spring structure and the plate spring structure. The protection device of the plate spring structure comprises two base plates used for being attached to the two surfaces of an auxiliary spring respectively. A wear-resistant pad is arranged on the inner surface of each baseplate. Side covers extending and covering the side edges of a plate spring are arranged on the two side edges of the base plates. A moving gap is reserved between the two side covers located on the same side. The protection device of the plate spring structure has the beneficial effects that the plate spring is covered with the base plates and the wear-resisting pads, the plate spring is preventedfrom making direct contact with a U-shaped bolt, therefore the plate spring is prevented from being abraded, it is effectively guaranteed that the axial clamping force of the U-shaped bolt cannot bereduced, and the service life of the plate spring is indirectly prolonged; and the side covers cover the side edge of the plate spring, lateral deviation between the base plates and the plate spring is effectively avoided, and meanwhile external foreign matter is prevented from cutting the side edge of the plate spring in the vehicle running process.

    本发明涉及汽车悬架零部件技术领域,具体为一种板簧结构的保护装置及板簧结构。该板簧结构的保护装置,包括分别用于贴合副簧两表面的两个基板;所述基板的内表面设置有耐磨垫;所述基板两侧沿均设有延伸并覆盖板簧侧边的侧盖;位于同侧的两个侧盖间预留有移动间隙。本发明的有益效果是:通过基板和耐磨垫覆盖板簧,避免板簧与U型螺栓产生直接接触,从而防止对板簧产生磨损,有效保证了U型螺栓的轴向夹紧力不会减少,间接提升板簧的使用寿命;通过侧盖遮盖板簧侧边,有效避免基板与板簧产生侧向偏移,同时防止车辆行驶过程中外部异物削切板簧侧边。
