MULTIPLE DISC CLUTCH APPARATUS

摘要

A multiple disc clutch apparatus configured to reduce the drag torque, the sticking torque, and simultaneously the weight of the multiple disc clutch apparatus. The apparatus can comprise substantially annular multiple clutch discs connected to an input-side from an engine; substantially annular multiple clutch plates alternately laminated with the clutch discs and connected to an output-side to a wheel; and frictional members secured on surfaces of the clutch discs opposing the clutch plates and adapted to press-contact with or separate from the clutch plates. A power from the engine can be transmitted to the wheel when the clutch discs and plates are press-contacted with each other; the power transmission being blocked by releasing the press-contacting force; wherein depressions are formed on each clutch plate along its periphery and radially inward therefrom; and wherein a part of the one or more frictional members is positioned within a region of the depressions.

1. A multiple disc clutch apparatus comprising:
substantially annular multiple clutch discs connected to an input-side from an engine; substantially annular multiple clutch plates alternately laminated with the clutch discs and connected to an output-side to a wheel; and frictional members secured on surfaces of the clutch discs opposing the clutch plates and adapted to be capable of press-contacting with or separating from the clutch plates; a power from the engine being transmitted to the wheel when the clutch discs and the clutch plates are press-contacted to each other via the frictional members and the power transmission between the engine and the wheel being blocked by releasing the press-contacting force characterized in:
that depressions are formed on each clutch plate extending along its periphery and radially inward therefrom; andthat a part of the frictional members is positioned within a region of the depressions when the clutch plates are alternately laminated with the clutch discs.
