ABSTRACT:
A synchronizer for a gear change box comprising a hub, a sleeve axially slidable on the hub and a cone clutch comprising an inner friction ring axially coupled to the hub, an outer synchronizing ring axially displaceable relative to the inner friction ring by the sleeve, and a double bevel ring disposed between the synchronizing rings, freely rotatable relative to the hub and frictionally gripped between the rings when the cone clutch is engaged, is assembled by a device comprising mounting stops for the outer synchronizing ring, the mounting stops being axially fixed with respect to the hub and distributed over the periphery thereof, a mounting stamp for axially loading the inner friction ring, means for axially loading the mounting stamp, means for controlling the loading means, and a load-sensing means for sensing the axial bias of the cone clutch, the load-sensing means being arranged between the outer synchronizing ring and at least one of the mounting stops, and the controlling means being responsive to the axial bias sensed.
