Novel limiting block structure

The invention provides a novel limiting block structure which comprises a rubber main spring and an inner metal part. The rubber main spring is mounted in the inner metal part. The interior of the rubber main spring is of a hollow structure. A boss is arranged on the inner metal part and can limit overall bounce displacement of a frame. The novel limiting block structure has the beneficial effectsthat overall bounce displacement of the frame can be limited by a product adopting the structure; the problem of accumulation of outside liquid is solved by the product adopting the structure; by means of the limiting block structure, bolt and product integration is achieved, and production efficiency can be improved easily; and after a novel limiting block is adopted for loading, the good capacity of absorbing vibration is achieved, and overall vehicle smoothness is greatly improved. 本发明提供了一种新型限位块结构，包括橡胶主簧、内金属件，所述橡胶主簧安装在所述内金属件上；所述橡胶主簧内部为中空结构，所述内金属件上设有凸台，所述凸台能限制车架整体的跳动位移。本发明的有益效果是：1.采用本发明的产品能限制车架整体的跳动位移；2.采用本发明的产品解决了
