Abstract
A sliding sleeve for a synchronous manual transmission assembly is produced by the following steps: a tubular blank is provided in which an internal toothing arrangement is present, and the blank which is provided with the internal toothing arrangement is further processed to form a plurality of sliding sleeves.
Claims18
A method of producing a sliding sleeve for a synchronous manual transmission assembly comprising the following steps:
- providing a tubular blank having a preformed internal toothing arrangement wherein the internal toothing arrangement is produced by cold pilgering rolling plastic deformation of the blank;
- further processing the blank to form a plurality of sliding sleeves;
- and
- wherein a pilger mandrel having different toothing pitches is utilized in the preforming of the internal toothing arrangement.
A method of producing a sliding sleeve for a synchronous manual transmission assembly comprising the steps of:
- providing a tubular blank having a preformed internal toothing arrangement having teeth which are associated with different toothing arrangements, and
- further processing the blank to form a plurality of sliding sleeves;
- wherein the teeth of the different toothing arrangements differ in terms of tooth width, tooth height, modulus, or tooth profile.
A method of producing a sliding sleeve for a synchronous manual transmission assembly comprising the steps in sequence of:
- providing a tubular blank having a preformed internal toothing arrangement produced by cold pilgering, after the internal toothing arrangement is introduced, providing the blank with an outer contour in sections, and
- then subdiving the blank into individual segment;
- and
- wherein the outer contour is produced by attaching at least one component.
