Abstract
A parking brake (10) for a transmission (12) of a motorized vehicle (14). An anchor (24) is located to support an actuator (26) interposed between the anchor (24) and a parking pawl (22) when the parking pawl (22) is in the engaged position with a toothed parking gear (20). The anchor (24) is defined by a plurality of stacked laminas (30). Each of the plurality of stacked laminas (30) is rigid and has at least one peripherally extending surface (32), wherein the at least one peripherally extending surface (32) of at least two of the plurality of stacked laminas cooperate to define at least one load-bearing surface (34), and wherein the plurality of stacked laminas (30) are secured together to prevent relative movement of any one of the plurality of stacked laminas (30) with respect to another of the plurality of stacked laminas (30) when a load is transmitted through the parking pawl (22) from the at least one load-bearing surface (34).
