Clutch Brake

A clutch brake for use in association with a braking mechanism for braking rotation of a shaft connecting an engine to a transmission, the clutch brake being generally annular in shape and comprising:

• first and second clutch brake sections;
• a friction surface on the first and second clutch brake sections adapted to face said braking mechanism and to selectively engage said braking mechanism for braking rotation of the shaft;
• the first and second clutch brake sections being selectively configurable in a disconnected configuration in which the clutch brake sections are adapted to be moved apart from one another and the clutch brake removed from the shaft with the shaft passing in a radial direction with respect to the clutch brake between the first and second clutch brake sections, and in a connected configuration in which the clutch brake encloses the shaft and the first and second clutch brake sections extend continuously along the circumference of the shaft and prevent the shaft from passing in a radial direction with respect to the clutch brake between the first and second clutch brake sections, whereby the clutch brake may be installed on and removed from the shaft without disconnecting the shaft from the transmission or the engine;
• said first section of the clutch brake comprising a first lock plate, said second section of the clutch brake comprising a second lock plate;
• and
• a fastening mechanism on the first and second lock plates for fastening the first and second clutch brake sections in said connected configuration;
• said fastening mechanism comprising a first fastening component on said first lock plate and a second fastening component on said second lock plate;
• said first fastening component comprising a fastener body movably mounted in an opening in said first lock plate, and a fastening arm extending from the fastener body;
• said fastener body being movable in said opening from a fastening position in which said fastening arm is in fastening engagement with said second lock plate to fasten the first and second clutch brake sections in said connected configuration, to a release position in which said fastening arm is not in fastening engagement with said second lock plate to allow the first and second clutch brake sections to be moved to said disconnected configuration.
