Vehicular friction clutch apparatus

摘要

To provide a vehicular friction clutch apparatus excellent in view of mountability to an ordinary vehicle, capable of simply and stably providing correlation between pinching force of facings and hydraulic pressure of a release cylinder device and having excellent stroke efficiency, there is provided a vehicular friction clutch apparatus for carrying out torque transmission between an engine and a transmission by pinching facings 12b of a clutch disk 12 by a flywheel 11 and pressure plates 13b integrally rotated with the flywheel 11 and capable of progressing and regressing to and from the flywheel 11 in which the pinching force of the facings is produced by pressing the pressure plates 13b to the flywheel by a hydraulic cylinder device 18. Preferably, there is provided a position adjusting device 20 for moving return position of a piston 18c when hydraulic pressure of a hydraulic operational chamber 18b formed by a cylinder 18a and the piston 18c of the hydraulic cylinder device 18 is discharged in a direction of enlarging a volume of the hydraulic operational chamber 18b by following wear of the facings.
