Abstract
In a clutch device 1, a clutch cover assembly 8 is attached to a second flywheel assembly 5 to bias elastically a frictional connection portion 54 against a friction surface 21a of a flywheel 21. A release device 10 releases the bias toward the frictional connection portion 54 by applying a load to the clutch cover assembly 8 in an axial direction toward the engine. A support plate 39 elastically supports the second flywheel assembly 5 such that the second flywheel assembly 5 can move in a bending direction. A bending direction movement suppression mechanism 24 suppresses bending movement of the second flywheel 5 by connecting the second flywheel assembly 5 to a disk-like member 13 when the clutch cover assembly 8 receives a load toward the engine in the axial direction.
Claims20
A clutch device for transmitting and stopping torque from a crankshaft of an engine to a transmission, comprising:
- a flywheel being movable in an axial direction relative to the crankshaft within a certain range, and having a friction surface on an axial side opposite to the engine;
- a damper mechanism being configured to connect elastically said flywheel with the crankshaft, said damper mechanism having elastic members;
- a clutch disk assembly having a frictional connection portion adjacent to said friction surface of said flywheel;
- a clutch cover assembly being attached to said flywheel to bias elastically said frictional connection portion against said friction surface of said flywheel;
- a release device being configured to release the bias toward said frictional connection portion by applying a load to said clutch cover assembly;
- a bending direction support mechanism being configured to support elastically said flywheel, said flywheel being movable in a bending direction;
- and
- a bending direction movement suppression mechanism being configured to suppress bending movement of said flywheel by connecting said flywheel to a crankshaft side member when said clutch cover assembly receives said load toward the engine in said axial direction.
