The light-weight heavy truck power suspension assembly comprises a vulcanized body and a base for installing the vulcanized body, and the vulcanized body comprises a core body and rubber main springs arranged on the two sides of the core body; the base is made of a composite material, and the outer wall of the base is of a closed-loop structure; the front end face and the rear end face of the closed-loop structure are open structures in the mounting direction of the vulcanized body; a reinforcing structure is arranged between the base and the rubber main spring, the reinforcing structure is of a plate-shaped structure or a sheet-shaped structure, and a limiting part bent towards the rubber main spring is arranged in the center of the plate-shaped structure or the sheet-shaped structure, so that the displacement of the vulcanized body is limited, and the vulcanized body is prevented from falling off. On the premise that the rigidity is guaranteed, the whole product meets the requirement for light weight. The base is made of light composite materials, the weight of the base is greatly reduced, meanwhile, in order to guarantee the strength of the suspension assembly, the metal reinforcing structure is arranged between the core body and the base, the Y-direction (transverse) bearing of the whole suspension assembly is increased through the design of the reinforcing structure, the middle of the reinforcing structure is designed to be provided with the through hole, and the through hole is formed in the middle of the reinforcing structure. And the requirement of light weight is further met.
本发明涉及一种轻量化重卡动力悬置总成,包括硫化体和安装硫化体的底座,所述硫化体包括芯体和设置芯体两侧的橡胶主簧;所述底座为复合材料材质,所述底座外壁为闭环结构;沿着硫化体的安装方向,所述闭环结构的前后端面均为敞开式结构;所述底座与橡胶主簧间设置有加强结构,所述加强结构为板状结构或片状结构,所述板状结构或片状结构中心设置有向橡胶主簧弯曲的限位部,实现对硫化体的窜动的限位,防止硫化体脱出。在保证刚度的前提下,使整个产品满足轻量化的要求。本发明将底座材料使用轻质的复合材料,大大减轻了底座的重量,同时为了保证悬置总成的强度,在芯体与底座之间设置有金属加强结构,通过将加强结构的设计,使整个悬置总成的Y向(横向)承载增加,并且将加强结构中间设计为通孔,进一步实现轻量化的需求。
