TORQUE AND/OR ROTATIONAL CONTROL APPARATUS

摘要

The multi-caliper brake (10) for positive torque controlling as well as for controlling the rotation of a shaft (12) has a hub (14) arranged to be mounted to the shaft (12) with a longitudinally centrally located, finned friction disc (16) mounted to the hub (14). A brake housing (36) supports multiple brake calipers (18-25) which are shown as including diaphragm operated, fluid pressure actuated pistons (26) carrying brake pads (32) which are caused to frictionally engage with the friction disc (16) to rotationally control the shaft (12). The calipers (18-25) include quick brake pad change apparatus by use of pinned pad supports and positioning bosses.
