摘要：: An electric mechanical brake assembly (10) includes a brake caliper housing (12), a ballscrew subassembly (14) at least partially located within the housing, first and second electric motors (16 and 18), and at least three gears (20-28). A linearly-movable member (32) of the ballscrew subassembly is attachable to a brake pad (34) and is driven by a rotatable actuation shaft (30) of the ballscrew subassembly. The gears operatively connect the drive shafts of the electric motors to the actuation shaft of the ballscrew subassembly. An electric-mechanical-brake motor subassembly (40) includes first and second electric motors, a motor plate (42), and at least three gears. The electric motors are attached to the motor plate, and the motor plate is attachable to a brake caliper housing. The gears arc operatively connectable to the motor drive shafts and to a rotatable actuation shaft, of a ballscrew subassembly at least partially located within the housing, for the drive shafts to rotate the actuation shaft. <IMAGE>
