Abstract
A synchronizer ring is made of steel and has a main body with a conical friction surface. A toothing and at least one blocking body project radially outward from the main body. The blocking body has an engagement section extending in the axial direction. The engagement section has a first edge, which runs approximately parallel to a first end face of the main body and has a first width extending in the circumferential direction, and two mutually opposite second edges extending from the first edge. To improve the durability of the synchronizer ring, the second edges have a convex curvature in a plan view of the engagement section. A second width extending in the circumferential direction between the second edges is greater than the first width at a depth spaced apart from the first edge.
