Abstract:
Continuously variable transmission is the ideal transmission mode, the Metal Pushing Continuously Variable Transmission (CVT) is the most mature CVT used in vehicle at present. By studying the transmission mechanism and ratio change characteristics of Metal Pushing Continuously Variable Transmission system, and using the bond graph theory, a bond graph model of continuously variable transmission is established in this paper, and the state space function is derived. Based on the model, The simulation of transmission characteristics of a CVT car is studied, the simulation result shows that the dynamic characteristics of continuously variable transmission could be expressed in this model. The research results can provide the theoretical analysis method and design basis for CVT vehicle.[WT5HZ]
