Abstract
A clutch-brake system in which at least one of clutch and brake devices has the following structure. A friction plate is mounted on a drive shaft to be synchronously rotatable on the drive shaft, but not to be movable in an axis direction of the drive shaft. First and second discs are provided on the opposite sides of the friction plate in the axis direction of the drive shaft, and movable in the axis direction. The first and second discs are synchronously moved in the opposite directions along the axis of the drive shaft, enabling to selectively switch between an operation state and a non-operation state.
Claims11
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.
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 brake device includes;
- a brake 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;
- and
- first and second brake discs provided on the opposite sides of the brake friction plate in the axis direction of the drive shaft, and movable in the axis direction,
- wherein the first brake disc has a cylinder structure and the second brake disc has a piston structure.
