The main function of automobile suspension is to transmit the force and moment between the wheel and the frame, and to buffer the impact force transmitted from the uneven road to the frame or body, reduce the vibration caused by this, to ensure that the car can smoothly Driving. Among them, the leaf spring is the most traditional elastic element in the automobile suspension system.
With the development of composite material applications, from various perspectives such as lightweight, material substitution, optimization of overall suspension system design, and improvement of vehicle performance, composite leaf springs are increasingly appearing in our field of vision. There are practical applications on multiple models.
GFRP composite leaf spring manufacturing process:
Fabric cutting: use automatic cutting machine to cut fabric into pre-shaped size;
Pre-forming: Put the cut fabric into the pre-forming mold through the robot for pre-forming;
Into the mold: Put the preformed fabric into the forming mold by the robot;
Glue injection molding: closing the mold and injecting resin into the molding mold, and curing it under a certain pressure and time;
Demoulding: Open the mold to eject the part, and use the robot to place it in the designated position;
Remove the burrs: remove the burrs of the parts;
Machining: the parts are placed on the tooling and processed into a specific shape by CNC;
Inspection: A qualified product will be obtained after 100% full inspection.
GFRP composite leaf spring material: glass fiber + epoxy resin
Advantages of GFRP composite leaf spring:
The quality of the main body is greatly reduced, and it is more than 60% lighter than the traditional steel structure leaf spring;
Good designability, high strength and long fatigue life;
Help the suspension system reduce the number of independent parts and simplify the structure and assembly process;
One-mold multi-cavity design can be mass-produced.
This horizontal composite material leaf spring design not only brings lighter unsprung mass, achieves the advantages of weight reduction and performance improvement, but also brings a flatter space layout for the body at the rear wheel position, which directly increases Space for the passenger compartment or luggage compartment.
