Abstract:
A brake appliance for gerotor motors, comprising,a housing having a center bore, an end cap having a center bore axially aligned with the center bore of the housing and secured to an inner end of the housing, an output shaft rotatably mounted in the center bore of the housing and having an inner end extending into the center bore of the end cap, an internal annular cavity in the end cap, a brake piston plate slidably rotatably mounted in the annular cavity of the end cap and adapted for slight longitudinal movement therein, an annular fluid pressure chamber comprising a port of the annular cavity in the end cap and being located adjacent an outer face of the brake piston plate so that pressurized fluid in the pressure chamber will exert a force on the brake piston plate in an inward direction, two groups of braking members, one group rotatably secured to the housing and the other group rotatably secured to the output shaft, primary spring means between the end cap and the brake piston plate for urging the two groups of braking members into a primary braking condition, secondary spring means between the brake piston plate and the two groups of braking members for urging the braking members into a permanent secondary braking condition, and connection means on the inner end of the output shaft for connection to an output shaft of a gerotor motor.
