Definitions
- the invention relates to an assembly for a synchronization for a manual transmission, having a first and a second synchronizer ring, which are interconnected.
- the synchronizer rings are arranged on one and the other side of a sliding sleeve and provided with a plurality of projections which extend through recesses in the sliding sleeve.
- the two synchronizer rings are connected to each other by the projections are welded together.
- the disadvantage here is the one that during welding a large amount of heat is introduced into the synchronizer rings. As a result, there is a risk that the material properties of the alloy used change, especially when it comes to hardened or tempered components. On the other hand, it is only possible with great effort, quasi produce a weld with the required quality in the interior of the sliding sleeve.
- the object of the invention is thus to develop an assembly of the type mentioned in that the two synchronizer rings can be coupled with less effort.
- the two synchronizing rings are connected by a positive connection. In this way, the two synchronizer rings can reliably connect with little effort with each other.
- each of the two synchronizer rings has at least two connecting straps which extend toward the respective other synchronizer ring. This allows the synchronizer rings through a other component of the synchronization through, for example, a shift sleeve or a transmitter to connect.
- each of the connecting straps is provided with a positive locking design. This embodiment is based on the recognition that a comparatively simple undercut is sufficient to reliably connect the synchronizer rings.
- the positive locking design is formed by a connecting projection on one of the synchronizer rings and a complementary receiving opening on the other synchronizer ring. This makes it possible to connect the two synchronizing rings as two parts of a puzzle with little effort with each other by the connecting projection of a synchronizing ring is inserted into the receiving opening of the other synchronizing ring.
- the positive locking design is freely movable in the radial direction.
- This embodiment is based on the finding that a fixation of the two synchronizing rings directly to each other in the radial direction is not necessary, but that it is sufficient to bring about the radial fixation by the assembly in the transmission.
- the positioning of the synchronizer rings by their associated friction surfaces or in a transmitter is sufficient to reliably exclude a release of the freely movable in the radial direction positive engagement design.
- the positive locking design is formed by a receiving opening in each of the two synchronizer rings, wherein a separate connecting element is provided, which engages in the two receiving openings. Even with such a separate connection element, the two synchronizer rings can be connected to each other with little effort.
- the connecting straps are embossed with each other. This also makes it possible to produce the positive connection for connecting the two synchronizer rings with little effort.
- the two synchronizer rings are identical. This increases the number of identical parts and thereby reduces the unit cost. Also, costs for the logistics are saved in the storage of various components.
- a unit with a transmitter and an assembly of the type mentioned above is provided for solving the above-mentioned objects. Such a unit facilitates the installation of the transmission considerably, since it does not have to be welded during assembly at a deep internal point.
- FIG. 1 in a schematic section a synchronization for a manual transmission with an assembly according to a first embodiment of the invention
- FIG. 2 shows the synchronization of FIG. 1 in a schematic exploded view
- FIG. 3 shows the assembly according to the first embodiment in a perspective view
- Figure 4 shows the assembly of Figure 3 attached to a transmitter
- Figure 5 shows a detail of an assembly according to a second embodiment of the invention
- FIG. 6 is a perspective view of an assembly according to a third embodiment of the invention.
- FIG. 1 shows a transmission shaft 10 on which two gear wheels 12, 14 are arranged.
- the two gear wheels 12, 14 are part of a gearbox, as it can be used in particular in motor vehicles.
- the associated with them further gears, with which together the gear ratios of the transmission are formed, are shown here as little as a second transmission shaft.
- the gear wheels 12, 14 are formed as idler gears and rotatably mounted on the transmission shaft 10.
- a transmitter 16 is provided here, which is rotatably mounted on teeth 18 on the transmission shaft 10, but is displaceable in the axial direction.
- the transmitter 16 is provided on both sides with a respective transmission toothing 22, which can be brought into engagement with a coupling toothing 20 which is associated with each gear wheel 12, 14.
- the transmitter 16 when a gear is to be switched, moved by a shift fork or shift claw not shown here in the axial direction on the transmission shaft 10 until one of the transmission teeth 22 engages the coupling teeth 20 of the gear wheel to be switched 12 or 14.
- two synchronizing rings 30 are provided, which are arranged on one side and the other side of the transmitter 16 and can cooperate with friction surfaces 32 associated with the gear wheels 12,14.
- Each synchronizer ring 30 has a friction body 34 which is annular. In the illustrated embodiment, each friction body 34 is slightly conically widened away from the transmitter 16. On the inside of the friction body 34, a friction lining 36 is provided. Depending on the friction system used, a friction lining may alternatively be provided on the outer surface of the friction body 34.
- the receiving opening 40 is executed undercut, so has to the free end of the connecting tab towards a constriction.
- the connecting projection 42 has a shape complementary to the receiving opening 40, ie it consists here of a wider head at the end, which is connected by a narrow web with the actual connecting strap 38.
- the two connecting straps 38 one is provided with the receiving opening 40 and the other connecting strap with the connecting projection 42.
- a synchronizer ring can be attached to the transmitter so that its connection tabs 38 extend completely through fixing holes 44 in the transmitter, so far that both the receiving opening 40 and the connecting projection 42 are freely accessible on the other side.
- the second synchronizer ring is mounted by inserting its connecting projection and its receiving opening like two puzzle pieces into the receiving opening and the connecting projection of the transmitter 16 fixed to the synchronizer ring.
- the two synchronizer rings are additionally provided with further tabs 46, which are used for the blocking function and the transmission of the synchronous torque.
- the synchronization is not related to the present invention, so that will not be discussed further.
- a different geometric shape may also be used, as long as an effective positive connection in the axial direction is produced.
- the receiving opening 40 could be L-shaped and the connecting projection 42 complementary designed as an L-shaped protruding tab.
- FIG. 5 shows an alternative embodiment which uses a receiving opening 40 on both synchronizer rings.
- the positive connection between the two synchronizing rings 30 is brought about here by a connecting element 48, which is generally elongated and has a thickening at each end.
- the connecting element 48 thus has a generally bone-like shape.
- the connecting element 48 can be held by suitable measures with the two receiving openings 40 in engagement, for example by pressing, caulking or embossing.
- FIG. 6 shows a further embodiment in which the positive connection between the two synchronizer rings 30 is formed by an embossing point 50 which is embodied on the connecting straps 38.
- the two connecting straps 38 are made so long that they overlap in the middle.
- each synchronizer ring exactly two connecting tabs 38, one of which is bent relative to a reference position to the outside and the other is bent inwards.
- the two synchronizing rings can be attached to one another in such a way that, when the arrangement is centered, their connecting straps 38 abut one another exactly.
