Abstract:
A load adaptive brake system for an appliance comprising:a motor; a drive wheel driven by said motor; a rotatable vessel; a brake surface fixed relative to a non-movable portion of said appliance; at least one brake shoe carried by said vessel to rotate with said vessel; a biasing mechanism engageable with said brake shoe to press said brake shoe into engagement with said brake surface; a cam carried on said vessel, but rotatable with respect thereto, and engageable with a portion of said brake shoe to overcome a bias of said biasing mechanism when said cam is rotated relative to said vessel in a first direction to disengage said brake shoe from said brake surface; and a coupling mechanism arranged between said drive wheel and said cam to selectively couple said motor to said vessel by rotation of said cam in said first direction when said drive wheel is rotating in one direction relative to said cam and to uncouple said motor from said basket when said drive wheel is rotating in a second, opposite direction relative to said cam.
