Abstract

A synchronizing ring (1) adapted for use in a gear clutch where the ring includes an annular body (2) formed of a chip-free material, such as a metallic body of forged or sintered material or a plastic, and having a generally conical friction surface (6) with a fibrous friction lining (3) cemented thereto. The ring has one or more generally axially extending grooves (5) formed in the friction material to provide for draining of oil during operation of the ring.
