Frequency influence research of the PWM-signal on the control range of pneumatic actuator of a dryfriction clutch
Abstract
To ensure quality clutch engagement in automatic mode during starting and maneuvering the control range of clutch actuator has to be maximum wide. It depends on the consistency of the actuator geometric parameters, solenoid valve characteristic, controller output stage and PWM frequency. In addition to electronic control the driver must be able to ma nually operate the clutch in emergency. That’s why clutch must have two independent control circuits. The objective of this study was to develop clutch automated drive with a duplicate circuit and research the influence of the PWM frequency to the control range of pneumatically actuated friction clutch.
