Abstract

Provided is a plate-type spring assembly (10) for a vehicle hanging device. The assembly includes a first plate spring (11), a second plate spring (12) arranged on the bottom side of the first plate spring, and a connecting mechanism (13) used for connecting the first plate spring and the second plate spring, wherein gaps are set between the two ends of the second plate spring and the first plate spring, and the length of the second plate spring is smaller than that of the first plate spring. The invention also provides the vehicle hanging device. The vehicle hanging device includes a pair of lifting lugs (18) and the plate-type spring assembly (10), wherein the both ends of the first plate spring are fixedly connected to the lifting lugs respectively. Since the plate-type spring assembly and the vehicle hanging device adopt the combination of the first plate spring and the second plate spring, the stiffness of the plate-type spring assembly can change along with the load change of a vehicle, and therefore, the technical problem that the stiffness of existing plate-type springs can not change along with the load change is solved, so that the specific stiffness, specific strength and corrosion resistance of vehicle hanging are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension devices, in particular to a leaf spring assembly and a vehicle suspension device. Background technique [0002] Composite materials, especially Fiber Reinforced Polymer / Plastic (FRP), are gradually replacing traditional engineering materials due to their light weight, high specific stiffness, high specific strength, long life, corrosion resistance, and good designability. , Such as: metal materials and wood, etc., are widely used in aerospace, aviation, navigation, construction, automobile, sports and medical equipment and other industrial fields. In recent years, the use of composite materials in the leaf springs of vehicle suspensions has also become more and more widespread. [0003] At present, most of the composite material leaf springs used for vehicle suspension adopt a single-leaf spring structure. Although the structure is simple, it is only suitable for vehicle suspensions wi...
