Study of Precision Formation on New Synchronizing Ring of Heavy-Duty Truck Based on Computer Numerical Simulation
Synchronizing ring, an important component of automotive synchronizer, uses the friction torque generated on its conical surface to synchro-mesh the two meshing components to realize gear shift. In the paper the forming of the hot precision forging of the new synchronizing ring is analyzed based on the finite element numerical simulation method, which provides evidence for processing optimization and mould modifying to get an accurate blank. In addition, the one-step forming processing for the synchronizing ring is analyzed, and the flow of the material, forming process, flaw prediction and the optimization of the mould structure is studied as well. The result indicates that it is more reasonable of the distribution of the material and it is more satiation filled of the cavities. The cycle life of new product development is reduced greatly by forming process analyzing and flaw prediction of the synchronizing ring.
