ABSTRACT:
A coaster brake hub including a housing having a generally cylindrical passage therethrough, an axle, a drive shaft, a drive cone, and a brake mounted within the passage. The passage has a surrounding wall. The hub also includes a clutch disposed within the passage mounted to the axle. The clutch is moveable between a first position and a second position. In the first position, the clutch rotatably interconnects the drive shaft with the brake such that rotation of the drive shaft in a first direction forces the drive cone into engagement with a portion of the passage wall to rotate the housing in the first direction. Rotation of the drive shaft in an opposite direction forces the brake into engagement with another part of the passage wall to brake rotation of the housing. In the second position, the clutch disconnects the drive shaft from the brake such that the rotation of the drive shaft in the first direction forces the drive cone into engagement with the portion of the passage wall to rotate the housing in the first direction. Rotation of the drive shaft in the opposite direction rotates the drive shaft in the opposite, direction relative to the drive cone such that upon subsequent rotation of the drive shaft in the first direction, the drive cone is forced into engagement with a portion of the passage wall to rotate the housing in the first direction.
