Clutch apparatus for vehicle

摘要

A clutch apparatus for a vehicle includes cancel mechanism having a weight member fitted for sliding movement in a clutch hub. The weight member is configured to slidably move in a radial direction of an output power shaft, and has an engaging portion at an inner end portion thereof along the radial direction. An elastic member biases the weight member toward the inner side along the radial direction of the output power shaft. A locking element is formed on the output power shaft or a locking member fixed to the output power shaft, and is configured to be engaged with the engaging portion from the opposite side to a pressure plate.

1. A clutch apparatus for a vehicle, said clutch apparatus comprising:
a clutch outer to which power from an internal combustion engine is inputted; a pressure receiving plate fixed to an output power shaft; a driving friction plate which is engaged by the clutch outer; a driven friction plate disposed in an opposing relationship to the driving friction plate; a pressure plate disposed to cooperate with the pressure receiving plate to sandwich the driving friction plate and the driven friction plate therebetween and movable in an axial direction of the output power shaft; a clutch hub disposed between the pressure receiving plate and the pressure plate in a direction along the axial line of the output power shaft configured to be engaged by the driven friction plate; a counter torque reduction mechanism which causes the clutch hub to press the pressure plate in a direction in which the pressure plate is spaced away from the pressure receiving plate in response to an input of rotational power from the output power shaft to the pressure receiving plate; and a cancel mechanism which is configured to invalidate a function of the counter torque reduction mechanism in a state in which a number of rotations of the clutch hub is equal to or lower than a predetermined rotational speed, the cancel mechanism including
a weight member fitted for sliding movement in the clutch hub, and configured to slidably move in a radial direction of the output power shaft, and having an engaging portion at an inner end portion thereof along the radial direction,an elastic member which biases the weight member toward an inner side along the radial direction of the output power shaft, anda locking element formed on the output power shaft or a locking member fixed to the output power shaft, and configured to be engaged with the engaging portion from the opposite side to the pressure plate.
