Embodiment Construction
[0041] figure 1 is a schematic structural diagram of a leaf spring assembly according to an embodiment of the present invention. Such as figure 1 As shown, a leaf spring assembly used in the automobile suspension system is fixed on the vehicle frame 10, used to transmit all directions of force and moment, and plays the role of guiding and buffering, including the main plate spring 1 and the secondary leaf spring 2 and guiding mechanism 3. The main plate spring 1 is made of steel material and is located above the axle 20 . The main plate spring 1 has an opposite first end 11 and a second end 12, wherein the first end 11 is connected to the outer side of the vehicle frame 10 for guiding longitudinal force. The auxiliary leaf spring 2 is made of composite material and is located above the main leaf spring 1 . The auxiliary leaf spring 2 is fixed on the top of the main plate spring 1 by a central bolt for buffering vertical force. In other embodiments, the secondary leaf spri...

The invention provides a plate spring assembly for an automobile suspension system and relates to the technical field of automobile parts. The plate spring assembly is connected with an axle and an automobile frame, is used for transmitting force and torque between the automobile frame and an automobile body, and achieves the effects of guiding and buffering. The plate spring assembly comprises amain plate spring, an auxiliary plate spring and a guiding mechanism. The main plate spring is made of a steel material, located above the axle and used for longitudinal force guiding. The auxiliary plate spring is made of a composite material, located above or below the main plate spring and used for buffering vertical force. One end of the guiding mechanism is connected with the automobile frame, and the other end of the guiding mechanism is connected with the main plate spring. A preset angle is formed between the guiding mechanism and the main plate spring, and the guiding mechanism is used for transverse force guiding. By adopting the plate spring assembly, lateral force borne by the auxiliary plate spring made of the composite material is reduced, the service life of the plate springassembly is prolonged, and the stability of an automobile is further improved.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a leaf spring assembly used in an auto suspension system. Background technique [0002] The car suspension system refers to a connection structure system between the body, frame and wheels. When the car is running on the road, it is subject to vibration and impact due to changes in the ground. Part of the force of these impacts will be absorbed by the tires, but absolutely Most of it is absorbed by the suspension device between the tire and the body. [0003] Automobile leaf spring is the most traditional elastic element in automobile suspension system. It is widely used because of its good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure. Automobile leaf springs are generally composed of several pieces of alloy spring steel with unequal lengths to form a group of similar-strength spring beams. [0004] In order to reduce ...
