Clutch apparatus

摘要

A clutch apparatus includes: a flywheel (4); a pressure plate (24) opposed to the flywheel; a clutch disk (10) disposed between the flywheel and the pressure plate; a clutch cover (21) that rotates together with the flywheel; a release bearing (25) disposed so as to be movable in an axial direction of the clutch cover; a release lever (22) having a pressured point (22a) for receiving pressure load from the release bearing, a pivot point (22b) at which the lever is pivotally supported by the clutch cover, and an action point (22c) which presses the pressure plate toward the flywheel; and a release mechanism (30;50) configured to move the release bearing based on an operation of a clutch pedal. The release mechanism includes a spring (40;54) having a spring load so as to be balanced with pressure load generated from friction surfaces of the clutch disk when the clutch is pressed by the flywheel and the pressure plate. The release mechanism includes a mechanism which uses working amount of the clutch pedal to have the load from the spring unbalance with the pressure load generated from the friction surfaces of the clutch disk.
