Patent number: 10578168Abstract: A synchronizer ring for a synchronization unit has a substantially constant sheet-metal cone which tapers in direction of its ring axis from a first axial cone end towards a second axial cone end. At the sheet-metal cone a centering collar is integrally molded and the sheet-metal cone includes a first sheet portion and axially adjacent a second sheet portion. In addition, the sheet-metal cone includes a step portion which axially extends between the second axial cone end and the first sheet portion, wherein a radial outer side of the step portion is offset with respect to a radial outer side of the first sheet portion towards the ring axis. Furthermore, there is shown a method for manufacturing a synchronizer ring.Type: GrantFiled: November 6, 2017Date of Patent: March 3, 2020Assignee: HOERBIGER ANTRIEBSTECHNIK HOLDING GMBHInventors: Christian Weiher, Martin Kees
