Abstract
A brake assembly of the constant friction type has a rotary transmission shaft fitted with a constant friction brake device including a first set of friction plates carried on the shaft and a second set of friction plates interleaved with the friction plate and mounted on a friction element support. The friction brake device acts on the shaft to apply a braking torque thereto in at least one direction of rotary movement. The friction element support is rotatable relative to the shaft and to a housing of the assembly. A detent mechanism acts between the housing and the friction element support so as to retain the support against rotation below a predetermined braking torque. A signalling means such as a proximity sensor is arranged to be operated when the friction element support moves relative to the housing.
