Problems solved by technology

However, a disadvantage of such a synchronizing mechanism provided with a reaction washer is that the thickness of the washer material and the positioning of the washer next to the spokes of the carrier element will increase the axial thickness of the synchronizing mechanism

Embodiment Construction

[0038] figure 1 A first synchronizing device 2 is shown, which is constructed from the constituent system according to the invention and contains a carrier element 6 which can be fitted on a rotatable gearbox shaft 4 and is fitted to the shaft 4 co-rotate, while said carrier element 6 comprises a hub 8 connectable to the shaft 4 (only shown in FIGS. 25-26 ) and spokes 10 projecting radially from said hub 8 . On the outer circumference of the spokes, the load-bearing element 6 has an outer part 12 which widens axially to the side and is provided on the outside with axial load teeth 14 (see Figure 13A ). On the outside of the outer part 12, the carrier element supports a sliding sleeve 16 (see Figure 21 ), the sliding sleeve 16 is mounted to rotate with the carrier element, but can move axially relative to the carrier element and surrounds the carrier element in an annular manner. The inside of the sliding sleeve is provided with axially ridged connecting teeth 18 which eng...

Abstract

Structuring system for synchronising devices for a gearbox, whereby the synchronising device comprises: a carrier (6) which is mounted on, and for joint rotation with, a gearbox shaft (4) and which has not only a hub portion (8) connected to the shaft but also a web portion (10), which carrier supports for joint rotation with it but axial mobility relative to it a surrounding shift sleeve (16) whereby the carrier can be coupled to a coupling element (22',22") fastened firmly to a gearwheel mounted rotatably on the shaft; at least one inner synchronising ring (28, 40) with conical outer friction surface; an outer synchronising ring (24a, 24b) with conical inner friction surface and external locking teeth (26); an intermediate synchronising ring (34) fitted between the inner and outer synchronising rings. The structuring system is usable for single, double or triple synchronisation versions, and the outer synchronising ring (24a, 24b) has driving protrusions (36a, 36b) which engage at least halfway in the web portion of the carrier. Each driving protrusion is situated in an engagement aperture (38). The synchronising ring (28, 34) immediately within the outer synchronising ring provided with locking teeth (26) has on its side facing away from the web portion of the carrier axial driving protrusions (30a, 30b) which each engage in respective adjacent coupling elements (22', 22").

Description

technical field [0001] The invention relates to a constituting system of a gearbox synchronizing device. Background technique [0002] Synchronizers of the type described above comprise a carrier element mounted on a rotatable shaft and arranged to rotate with said shaft, and having a hub and spokes supporting bearings that can communicate with said carrier element Co-rotating but axially displaceable sliding sleeves (synchronous sleeves), the movement of which enables the carrier element and thus the shaft to be connected to a connecting element belonging to the gearbox gear. Such a connecting element may take the form of being part of the same gearbox gear, or an element firmly connected to said gear. The synchronization device also includes at least two synchronization rings having cooperating conical friction surfaces. [0003] Synchronization devices of this type are known and include various modes that can be designed to achieve single, double or triple synchronizati...
