The design of auto clutch control system for heavy-duty off-road vehicles

A set of automatic clutch control system is designed based on the operating characteristic and structure analysis of heavy-duty off-road vehicle clutch and gas power type hydraulic control mechanism. The functional requirements of automatic separating, engaging and maintaining of the clutch are realized. The system has the function of clutch emergency manual control to ensure the battlefield survivability of heavy-duty off-road vehicles. The collaborative optimization method is used to design the oil cylinder, which is the core component of the automatic operation control. In order to obtain the characteristics of the designed automatic clutch control system, a test bench is designed to test the separation, joint and fixed-point control. The test results show that the response speed and control precision can meet the operating requirement.
