Design of Automatic Clutch System and Simulation of Engagement Process for AMT

Abstract:

In this paper the executive mechanism and electric-hydraulic control system for AMT automatic clutch were designed. A hydraulic cylinder was applied as the actuator. The hydraulic source with constant pressure using electric oil pump was designed. The basic idea lies in using pulse signal with variable duty cycle to drive high-speed solenoid valves in the process of regulating hydraulic circuits. Hydraulic oil drives the cylinder to realize the control of dry clutch. At last, the actuator was modeled and simulated based on AMESIM. From the analysis of the simulation results, the system mentioned in this paper can meet the performance requirements of AMT equipped with automatic clutch.
