Electrically actuated disc brake assembly

摘要

A disc brake assembly (12) has a hub (14) that is rotatable about an axis (16) and at least a pair of discs (18, 19) supported on the hub (14) for relative axial movement along the axis (16) of the hub (14) with the discs (18, 19) having opposite sides presenting braking surfaces (100). A non-rotatable support structure (24) supports a plurality of friction elements (26) for relative axial movement into and out of frictional braking engagement with the braking surfaces (100) of the discs (18, 19). An electric actuator (28) is mounted on the support structure (24) adjacent at least one of the friction elements (26) and is operative when actuated to move the friction elements (26) into frictional braking engagement with the braking surfaces (100) of the discs (18, 19).
