Title: Flexible plate and flywheel assembly using flexible plate
Inventor: SHIMIZU MASARU
IPC: F16F15/30
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To absorb the bending vibration of a crank shaft in good performance and reduce noise emission at accelerating while the clearness in clutch disengagement is well maintained. SOLUTION: A flexible plate 4 consists of a disc in which the end of a piston on the side receiving a load resulting from the bending vibration is cut off partially in the circumference, and has cut edges 4e and 4f. Accordingly the diameter of the piston on the side receiving the load resulting from the bending vibration is smaller than the diameter on the other side, and therefore, the bending rigidity of the piston on the side receiving the load resulting from the bending vibration is smaller than the bending rigidity on the other side. Thus the resultant flexible plate 4 has an anisotropic bending rigidity.
