Abstract:
An electro mechanical brake assembly, characterized by:a brake disk stack; a housing including a guideway; and a ram nut guided by said guideway for movement toward and away from said brake disk stack, said guideway and ram nut respectively having polygonal cross-sections defined by plural outer side surfaces which rotationally interfere with one another to restrain rotation of said ram nut relative to said housing; a lead screw in threaded engagement with said ram nut whereupon rotation of said lead screw effects linear movement of said nut for selective movement into and out of forceful engagement with the brake disk stack for applying and releasing braking force on a rotatable wheel; and an electric motor drivingly connected to said lead screw gear for rotating said lead screw to effect movement of said ram nut toward and away from said brake disk stack.
