Differential for a parking brake assembly

摘要

The present teachings relate to a brake assembly, and more particularly to a differential for a brake assembly that is unlocked or open in one configuration and locked or closed in another configuration. The brake assembly comprises a differential and one or more output shafts. During rotation of at least one of the one or more output shafts a brake apply is created or released. During creation of the brake apply, the differential distributes a rotational force to each of the one or more output shafts until at least one of the one or more output shafts experiences higher resistance and then the differential re-distributes the rotational force to at least one of the one or more output shafts with lower resistance. During release of the brake apply, the differential distributes an opposing rotational force equally to each of the one or more output shafts.

1. A brake assembly comprising:
i. a differential; and ii. a pair of output shafts, wherein during rotation of at least one of the output shafts a brake apply is created or released, wherein during creation of the brake apply, the differential is unlocked and distributes a rotational force to both of the output shafts until one of the output shafts experiences a higher resistance than the other of the output shafts and then the differential re-distributes the rotational force to the other of the output shafts with lower resistance, and wherein during release of the brake apply, the differential is locked so that an opposing rotational force is distributed equally to both of the output shafts.
