摘要： The present invention provides a brake shoe formed of sheet metal and allowing a brake lining to be firmly bonded, and a method of simply and inexpensively producing the brake shoe. The brake shoe is comprised of a shoe rim 11 formed in a cylinder having a circumference partially notched and an outer surface with a brake lining 10 bonded thereto, a pair of shoe ribs 12 extending from a vicinity of an inner, axially center circumference of shoe rim 11 radially inward toward each other, and an attachment plate 13 extending between paired ribs 12 radially inward, wherein shoe rim 11 has an outer surface knurled 14. The brake shoe is produced by: cleaving and spreading an outer peripheral portion of a metallic, disk-shaped blank 20 in a direction of a thickness of the sheet metal to form an intermediate, rolled product having a short cylindrical portion 33 and a web 34 extending radially inward from a vicinity of an inner, axially center circumference of cylindrical portion 33; subsequently pressing a knurling barrel 39 against an outer circumferential surface of cylindrical portion 33 to knurl 14 the outer circumferential surface of cylindrical portion 33; and punching the intermediate, rolled product to obtain brake shoe 1, shaped as described above.

摘要： An electric brake actuator (14), including a rotatable member (21) and electric drive means (34) for driving the rotatable member (21) to rotate. The rotatable member (21) is arranged for engagement with a continuous cable (18) that in use extends between and in connection with a pair of brake assemblies (12) that are operable when actuated to apply a braking load to brake a wheel associated with each respective brake assembly. The rotatable member (21) is arranged such that it is operable to pull the cable (18) on each side of the rotatable member (21) upon rotation of the rotatable member (21) in a first direction, for actuation of the brake assemblies (12), and to extend the cable (18) on each side of the rotatable member (21) upon rotation of the rotatable member (21) in a second and reverse direction.
