VERFAHREN ZUR HERSTELLUNG EINER RASTIERUNGSHÜLSE, INSBESONDERE FÜR EIN SCHALTGETRIEBE

摘要

In previously known methods, welded joints have to be produced which result in inaccuracies regarding size and shape. The aim of the invention is to make it possible to produce locking sleeves with great accuracy. Said aim is achieved by a novel method comprising the following steps: a) a tubular blank (10) is cut to length from a metal pipe in the form of a pipe section; b) the diameter of the tubular blank (10) is increased or reduced along the axial length thereof such that a sleeve-shaped basic element (14) having a graduated diameter is formed; c) the basic element (14) is given its final geometrical shape by means of at least one pressing process; and d) a gate (16) is cut into the basic element (14) so as form the locking sleeve (1). The inventive method makes it possible to produce a metallic locking sleeve (1) encompassing a gate (16) with great accuracy. Said locking sleeve (1) is part of a gearshift dome that forms the connection between the inner gearshift mechanism of a manual transmission and an associated selector lever.
