Method to manufacture coupling ring for synchronisation unit of vehicle gear unit; involves bending sheet metal strip to form cylindrical body and connecting end sides with positively fitting elements

摘要

The method involves cutting or shaping a sheet metal strip to the right length, bending it to form a cylindrical body and connecting the end sides. The sheet metal strips are formed with elements (5) to positively connect the end sides, which are inserted into one another during or after the bending process. The elements are positively fixed tangentially along the ring ends and parallel to the ring axis.
