Abstract
A process is described which serves to assemble a synchronizer for a gear change box, which synchronizer comprises a hub provided with a slidable sleeve and at least one cone coupling comprising a double-conical ring, which is freely rotatable relative to the hub and is adapted to be non-positively gripped between an inner friction ring, which is connected to the hub, and a synchronizing outer ring, which is axially displaceable relative to the friction ring by the slidable sleeve, wherein the clutch in an engaged position is moved to engage the synchronizing outer ring with a locating abutment to ensure an axial lost motion between the synchronizing ring and the hub, and the friction ring is subsequently axially fixed to the hub and thereafter the locating abutment is removed. To permit an exact adjustment of the axial lost motion, it is proposed that a predetermined axial force is exerted on the inner friction ring, when it is held to be axially displaceable on the hub substantially without friction, and when the cone clutch is in an engaged state the synchronizing ring is moved by said axial force exerted on said friction ring into engagement with said locating abutment to locate the inner friction ring on the hub in a fixed axial position, whereafter the inner friction ring is axially fixed to the hub in that axial position.
