Embodiment Construction

[0033] figure 1 The outer ring of the "synchronizer", which is not shown in detail here, is shown. The synchronization device comprises an outer ring, an optional (not shown here) middle ring and an inner ring (not shown here). The "outer ring" is referred to as synchro ring 1 in this specification. Synchronizing ring 1 has a cone 2 , on the outside of which a retaining tooth 3 is integrally formed. The locking tooth 3 has a recess in which a reference web 4 and one or more centering webs 5 are arranged. The radially outer underside of the centering web 5 is identified with the reference numeral 6 . The underside 6 lies within a predetermined centering radius Z.

Abstract

The invention relates to a method for manufacturing a synchronizing ring (1), which has a conical body (2) and a centering splice (5) arranged on the periphery of the conical body (2). The method comprises following steps: manufacturing the centering splice (5) that extends radially from the conical body (2), and making the centering splice (5) bend towards the conical body (2) so that after bending, a part of the lower side (6) of the radial external part of the centering splice (5) is arranged within a preset centering radius (Z). In order to improve the strength of the centering splice (5),before the bending of the centering splice (5), the first section (A1), which is arranged in the radial inner part of the centering splice (5) and is connected to the conical body (2), has a maximalfirst thickness (d1), and the first thickness is greater than a second thickness (d2) of a second section (A2), which extends radially from the first section.

Description

technical field [0001] The invention relates to a method for producing a synchronizer ring and a synchronizer ring for a transmission. Background technique [0002] A method according to the preamble of claim 1 and a synchronized ring according to the preamble of claim 13 are known, for example, from WO 2010 / 130366 A1. In said known method, the synchronizer ring is produced by means of a plurality of successive forming steps. First, the preform is produced from sheet metal by means of stamping. A cone is then produced from the preform by means of deep drawing and alignment, from which cone at least one centering web extends radially. Thereafter, the centering web is bent in the direction of the cone such that the radially outer underside extends substantially in the axial direction and lies within a predetermined centering radius. Typically 3 to 6 centering webs are provided on the synchronizing ring, sometimes more than 6 centering webs are also provided. [0003] As a ...
