Synchronizer ring
First Claim
1. A synchronizer ring made of deep-drawable sheet metal, comprising:
- a ring-shaped sheet metal body having a conical section arranged between a wall and a hub surface;
the conical section having a conical inner friction surface and a conical outer installation surface;
one or more radially outwardly projecting guide elements defined by radially outwardly projecting tapered indentations integrally formed with the ring-shaped sheet metal body;
the wall being located at a largest conical diameter side of the ring-shaped sheet metal body and extending substantially perpendicular to a ring body axis;
gear teeth arranged on a radially outer end of the wall;
the one or more guide elements arranged between the conical section and the hub surface;
said one or more guide elements being configured to provide centering guidance relative to a hollow cylindrical surface of a synchronizer ring hub, whereby the ring-shaped sheet metal body is centered with respect to the synchronizer ring hub when a hub surface end of the ring-shaped sheet metal body is slid into the synchronizer ring hub;
one or more anti-rotation members projecting or extending from the largest conical diameter side of the ring-shaped sheet metal body toward a direction of the hub surface; and
said one or more anti-rotation members being adapted to extend into a respective opening arranged in the synchronizer ring hub.

Abstract
Synchronizer ring made of deep-drawable sheet metal. The ring includes a ring-shaped sheet metal body having a conical section arranged between a wall and a hub surface. One or more radially outwardly projecting guide elements are defined by radially outwardly projecting tapered indentations integrally formed with the ring-shaped sheet metal body. The wall is located at a largest conical diameter side of the ring-shaped sheet metal body and extends substantially perpendicular to a ring body axis. Gear teeth are arranged on a radially outer end of the wall. The one or more guide elements are configured to provide centering guidance relative to a hollow cylindrical surface of a synchronizer ring hub.

22. A synchronizer ring made of deep-drawable sheet metal, comprising:
-
a sheet metal ring body having a conical section arranged between a wall and a hub end; the conical section having a conical inner friction surface and a conical outer installation surface; plural radially outwardly projecting centering guide elements defined by radially outwardly projecting tapered indentations integrally formed with the conical section; the wall being located at a largest conical diameter side of the ring body and extending substantially perpendicular to a ring axis; gear teeth arranged on a radially outer end of the wall; the plural centering guide elements extending to the hub end; each centering guide element comprising at least one of; converging outer edges which converge toward one another as they approach a radially outer edge; and a rounded radially outer edge; said centering guide elements being configured to provide centering guidance relative to a hollow cylindrical surface of a synchronizer ring hub, whereby the ring body is centered with respect to the synchronizer ring hub when the hub end of the ring body is slid into the synchronizer ring hub; plural integrally formed anti-rotation members projecting or extending toward a direction of the hub; and said plural anti-rotation members being configured to extend into openings arranged in the synchronizer ring hub when the hub end of the ring body is slid into the synchronizer ring hub.

23. A synchronizer device comprising:
-
a sheet metal ring member having an integrally formed conical section arranged between; an integrally formed wall with a gear; and a hub end; the conical section having a conical inner surface and a conical outer surface that is substantially parallel to the conical inner surface; plural radially outwardly projecting centering guide elements integrally formed with the conical section and being defined by radially outwardly projecting tapered indentations; the wall with the gear being located at a largest conical diameter side of the ring member and extending substantially perpendicular to a ring member axis; the plural integrally formed centering guide elements extending to the hub end and having radially outer rounded edges; a synchronizer ring hub comprising an inner cylindrical surface and anti-rotation openings; said guide elements being configured to provide centering guidance relative to the cylindrical surface of the synchronizer ring hub, wherein the ring member is centered with respect to the synchronizer ring hub when the hub end of the ring member is slid into the synchronizer ring hub; plural integrally formed anti-rotation members projecting or extending toward a direction of the hub; and each anti-rotation member extending into a respective anti-rotation opening arranged in the synchronizer ring hub when the hub end of the ring member is slid into the synchronizer ring hub.
