ABSTRACT:
A clutch brake arrangement for farm working machinery etc., includes a boss parallel with an output shaft extending from an engine mount, a rotary member rotatably mounted on the output shaft, a pressure plate mounted on the boss in such a manner that it is slidable along the axial direction of the output shaft, the plate being provided for pressing a lining plate rotatable with the rotary member, a brake spring resiliently disposed between the engine mount and the pressure plate, and cam plates opposed to each other through the pressure plate and a cam ball and fitted over the end of the boss by a retaining ring. In this way, the arrangement can be brought near the engine mount, whereby the length, as viewed in the axial direction of the output shaft, and hence size of the arrangement can be decreased. Furthermore, since the movement of the operating mechanisms along the axial direction of the output shaft is slidably guided by the boss, the parallel movement thereof is made so smooth and reliable that clutch engagement and disengagement can effectively be carried out. A variation of the foregoing arrangement wherein a dust cover for covering the arrangement is attached directly to the engine mount, and between the duct cover and the pressure plate is resiliently disposed a brake spring, by which the dust cover is engaged with, and held on, the engine mount. In this way, it is possible to simplify and make sure the mounting structure of the dust cover, thus resulting in a decrease of the number of the parts involved and improvements in working efficiency.
