Abstract:
A clutch-brake device provided on a driving force delivery system which delivers a driving force inputted into a fly wheel to a gear, comprising:a stationary member rotationally supporting said fly wheel; a rotation shaft, having at least one part rotationally supported by said stationary member, delivering said driving force to said gear; a multi-disk clutch being between a case member affixed to said fly wheel and a rotation input part of said rotation shaft; a multi-disk brake being between said stationary member and said rotation input part of said rotation shaft; a fluid pressure cylinder, rotating as a unit with said fly wheel, switching said multi-disk clutch and said multi-disk brake; a piston member in said fluid pressure cylinder; an output part, on said piston member of said fluid pressure cylinder, effective for transferring a pushing force of said piston member to a clutch plate which rotates as a unit with said case member, whereby relative rotation does not exist between said output part and said clutch plate, and frictional wear therebetween does not occur; and said piston member extending fully across said fluid pressure cylinder to develop said pushing force.
