A synchronizer body ( ) of a synchronizing device for manual transmissions comprising a base body ( ) made out of sheet metal by shaping, an inner toothing ( ), and an outer toothing ( ) and at least one reception ( ) formed in the base body ( ) for receiving a spring-loaded detent element ( ) forms an assembled unit with the spring-loaded detent element ( ).

Synchronizer body comprising an integrated detent element

In a sliding sleeve ( ) of a synchronizing unit having inward directed teeth ( ) configured on the inner periphery of the sliding sleeve, the teeth ( ) comprise recesses ( ) formed by plastic displacement of material out of the teeth ( ).

Slip joint of a synchronization unit for transmissions

An arrangement of non-machined sheet metal synchronizer rings ( ) is provided, the outer synchronizer rings ( ) of which are provided a radial, outwardly projecting gear ring and a radial, outwardly directed flange ( ).

Assembly and realisation of synchronisation rings in the form of sheet metal parts shaped without cutting

A synchronizing ring ( ) having a substantially cone-shaped annular body ( ) is made by shaping out of sheet metal and is provided on its end section ( ) having the small cone-diameter, with stops ( ) that extend in radial direction beyond the contour of the outer peripheral surface of the annular body ( ).

Synchronizing ring which is shaped without cutting

A sliding sleeve of a synchronizer assembly for manual transmissions, said sliding sleeve having a sleeve body made by a non-chipping shaping procedure which sliding sleeve receives a gearshift fork guide on an outer peripheral surface and has a toothing extending in a direction of a central longitudinal axis of the sleeve body on an inner peripheral surface wherein the sleeve body is made as a one-piece component of sheet metal by a non-chipping shaping procedure.

Sliding sleeve of a synchronizer assembly for manual transmissions

The invention relates to an indexing gear (21) for a synchronizing device (1) for a geared speed change transmission installed in motor vehicles to which a coupling body (22) as well as a friction ring (23) are allocated. In accordance with the invention, the indexing gear (21), the coupling body (22) as well as the friction ring (23) are constructed as component parts which can be prefabricated, which are joined in a rotatably fixed manner.
