Abstract:
A clutch-brake system comprising:a flywheel; a drive shaft driven by rotational energy transmitted from the flywheel; a clutch device selectively switchable between an operation state in which the rotational energy from the flywheel is transmitted to the drive shaft, and a non-operation state in which no rotational energy is transmitted to the drive shaft; and a brake device selectively switchable between an operation state in which a braking force is applied to the drive shaft during rotation, and a non-operation state in which the braking force is released to permit rotation of the drive shaft, wherein the clutch device has; a clutch friction plate mounted on the drive shaft to be synchronously rotatable on the drive shaft, but not to be movable in the axis direction of the drive shaft; first and second clutch discs provided on the opposite sides of the clutch friction plate in the axis direction of the drive shaft, and movable in the axis direction; a first cylinder chamber which houses the first clutch disc; and a second cylinder chamber which houses the second clutch disc.
