Abstract
A brake device for braking a shaft including a number of rotors rotatable with the shaft and at least one stator interposed among the rotors. The frictional force generated between the rotors and the stator is fed back to a rotatable pressure plate to assist in braking the shaft. In a first embodiment, a projection of the pressure plate engages one of a number of toothed portions that are provided on one of the stator elements to transmit force from the stator elements back to the pressure plate. In a second embodiment, a linkage element for turning the pressure plate also engages one of the toothed portions on the stators, thus transmitting force from the stator back to the pressure plate to assist in braking.
