Embodiment Construction

[0037] Figure 1 to Figure 3 Shown is a synchronizing ring 10 for a synchronizing unit 12 of a manual transmission, which has a ring axis A and is formed by an annular sheet metal cone 14 with a substantially constant ring thickness t.

[0038] The annular sheet metal cone 14 has a conical radial outer side 16 and an opposite radial inner side with a conical friction surface 18 , wherein the ring thickness t corresponds to the dimension of the sheet metal cone 14 perpendicular to the friction surface 18 .

[0039] The sheet metal cone 14 tapers from a first axial cone end 20 to a second axial cone end 22 .

[0040] The sheet metal cone 14 is bent radially outwards at its first axial cone end 20 and includes locking teeth 24 .

[0041] The sheet metal cone 14 has at its second cone end 22 a face base 26 which extends radially from the sheet metal cone 14 towards the ring axis A at the second axial cone end 22 .

Abstract

A synchronizer ring for a synchronization unit has a substantially constant sheet-metal cone (14) which tapers in direction of its ring axis (A) from a first axial cone end (20) towards a second axialcone end (22). At the sheet-metal cone (14) a centering collar (28) is integrally molded and the sheet-metal cone (14) includes a first sheet portion (34) and axially adjacent a second sheet portion(36). In addition, the sheet-metal cone (14) includes a step portion (40) which axially extends between the second axial cone end (22) and the first sheet portion (34), wherein a radial outer side (42) of the step portion (40) is offset with respect to a radial outer side (38) of the first sheet portion (34) towards the ring axis (A). Furthermore, there is shown a method for manufacturing a synchronizer ring (10).

Description

technical field [0001] The invention relates to a synchronizing ring for a synchronizing unit of a manual transmission, comprising a ring axis and an annular sheet metal cone having a substantially constant ring thickness, wherein the annular sheet metal cone comprises radially outer surfaces with conical friction The opposite radial inner side of the surface, and wherein the annular sheet metal cone tapers in the direction of the ring axis from the first axial cone end towards the second axial cone end. On the radially outer side, the sheet metal cone comprises a centering collar formed in one piece to center the synchronizing ring radially relative to the synchronizing hub of the synchronizing unit, wherein the sheet metal cone is deformed in the region of the centering collar, And comprising a first plate portion having a reduced residual thickness compared to the ring thickness, and an axially adjacent second plate portion having a collar thickness at least corresponding t...
