    The invention relates to a synchronizer between two rotating components with a clutch between a non-rotatably seated on a shaft hub and one of the hub with respect rotatably mounted coupling body, wherein the clutch has a sliding sleeve with an internal dog teeth over which the sliding sleeve on a jaw ring Hub mounted axially displaceable and can be pushed onto a Kiauenkranz the coupling body for coupling.
    In gear change gears with a non-rotatably seated on a shaft hub and a rotatably mounted on the shaft gear wheel, it is customary to provide between the hub and the gear wheel a synchronizer with a cone clutch having, for example, a rotational drive of the gear wheel causing double cone ring, which between an inner Friction ring and an axially adjustable by the sliding sleeve relative to this friction ring, the hub associated synchronizer ring is clamped non-positively. If the sliding sleeve is displaced on the hub in the sense of a clutch engagement, the double cone ring is frictionally accelerated by the axial entrainment of the synchronizer ring via the spring-loaded thrust pieces between the inner friction ring and the outer synchronizer ring and thus the gear wheel rotatably connected to the double cone ring to the rotational speed of the hub. what allows the subsequent, unobstructed clutch engagement between the sliding sleeve and the claw ring of the gear wheel. A arranged on the synchronizer ring, cooperating with the claws of the sliding sleeve locking teeth prevents the sliding sleeve during synchronization can perform the axial coupling movement. 2
    In the same way, known synchronizers for clutches work between two shafts, one of which carries the hub with the sliding sleeve and the other forms the coupling body
    Regardless of whether the synchronizer is used for a gear change gear or a switchable shaft coupling, the axial displacement position of the sliding sleeve is determined by acting on the sliding sleeve shift fork, which requires a constructive determination of the shift fork position in the uncoupling position of the clutch between the hub and the coupling body.
    The invention is therefore the object of a synchronizer of the type described in such a way that to set the shift fork position for the uncoupling position of the clutch sufficient simple design measures.
    The invention solves this problem by the fact that the hub on the side facing away from the coupling body end forms at least one radially above the jaw ring projecting stop for the sliding sleeve, which receives the stop in a front stop notch.
    Since in synchronizing between two rotating components, whether between a hub and a gear wheel or between two shafts, the shift sleeve from a predetermined starting position is only to move in one direction in the coupling position, this starting position by one of the hub associated, axial stop for the sliding sleeve are determined constructively, which thus also dictates the position of the shift fork for this shift sleeve position, without increasing the axial length of the synchronizer. The projecting radially outwardly beyond the claw ring of the hub stop yes intervenes in the stop position of the sliding sleeve in the provided in the sliding sleeve, end stop stop recess, so that in the stop position neither the 3rd
    Stop yet the hub needs to protrude axially over the front side of the shift sleeve needs. Added to this is that a radially attached to the hub, projecting beyond the claw ring stop powder metallurgy easily without special tool overhead, as is also true for the stop recess in the shift sleeve, so that for sintered hubs and shift sleeves post-processing of these construction parts for manufacturing of the stop or the stop recess is unnecessary.
    So that no torque load about a transverse axis can occur on the sliding sleeve over the stop of the hub, it is advisable to provide three evenly distributed over the circumference of the hub attacks. Since usually three spring-loaded, displaceable by the shift sleeve plungers for axially acting on the provided with a locking teeth synchronizer ring of a cone clutch in the hub are provided, the attacks can be advantageously distributed between these pressure pieces distributed over the circumference.
    In the drawing, the subject invention is shown, for example. Show it
    Fig. 1 shows a synchronizing device according to the invention for a switchable shaft coupling in a schematic, partially torn view of the clutch body facing away from the end face and Fig. 2 is a section along the line ll-ll of Fig. 1 on a larger scale.
    The illustrated synchronizer is provided on a shaft 1 which is freely rotatably supported relative to a coupling body 2. This coupling body 2 may be rotatably mounted on the driven shaft 1 in a gear change gear and rotatably connected to a gear wheel. In the illustrated embodiment, the Kupplungsköiper 2, however, represents a further wave, which can be drive-connected by means of a clutch 3 optionally with a non-rotatably seated on the shaft 1 hub 4. The clutch 3 has a sliding sleeve 5, which is mounted axially slidably via an inner dog teeth 6 on a jaw ring 7 of the hub 4 and with the aid of a in the 4th
    Fig. 1 dash-dotted lines indicated shift fork 8 on a jaw ring 9 of the coupling body 2 can be pushed.
    In order to operate the clutch 3 only when the speed of the hub 4 coincides with that of the coupling body 2 to be coupled, a synchronizer is provided which comprises an inner friction ring 10, an outer synchronizer ring 11 and a double cone ring 12. However, the formation of the cone clutch with a double cone ring is by no means mandatory. While the friction and synchronizer rings 10,11 are assigned to the hub 4, the double cone ring 12 is rotatably connected to the coupling body 2 via drivers 13 which engage in corresponding receptacles 14 of the coupling body 2. The synchronizer ring 11, which forms a cone clutch with the friction ring 10 and the double cone ring 12, is axially slidably mounted relative to the friction ring 10 on the hub 4 and coupled to the friction ring 10 via driver 15 for rotational driving.
    So that the sliding sleeve 5 can be brought into engagement with the claw ring 9 of the coupling body 2 only after a synchronization of the rotational speeds of the hub 4 and the coupling body, the limited compared to the sliding sleeve 5 rotatable synchronizer ring 11 is provided with a locking toothing 16, with the dog teeth. 6 the sliding sleeve 5 cooperates. If the sliding sleeve 5 is displaced from its drawn center position against the coupling body 2, then distributed over the circumference of the hub 4, coupled via a spring catch 17 with the sliding sleeve 5 thrust pieces 18 axially pressed against the synchronizer ring 11, so between the synchronizer ring 11 and the friction ring 10 on the one hand and the double cone ring 12 on the other hand, a frictional connection is made with the effect that speed differences between the synchronizer ring 11 and the coupling body 2 are compensated. Since in this synchronization, the end faces of the dog teeth 6 of the sliding sleeve 5 are pressed against the Sperrver-toothing 16, a penetration of the dog teeth 6 of the sliding sleeve 5 is locked on the jaw ring 9 of the coupling body 2. Only after the reduction of the frictional torque caused by the synchronization, the 5 through the sloping roofs of the adjacent end faces of the dog teeth 6 and the locking teeth 16 in cooperation with the axial force of the sliding sleeve 5 conditional torque for mutual rotation of synchronizer ring 11 and sliding sleeve 5 can be exploited to introduce the dog teeth 6 of the sliding sleeve 5 past the locking teeth 16 of the synchronizing ring 11 in the claw ring 9 of the coupling body 2, whereby the coupling operation is completed.
    As can be seen in particular from FIG. 2, the hub 4 has at least one stop 19 for the sliding sleeve 5 projecting radially over the claw ring 7 on the end opposite the coupling body 2. The sliding sleeve 5 is provided for this purpose with a frontal stop recess 20 into which the stop 19 engages in the stop position of the shift sleeve 5. Because of the engagement of the stop 19 of the hub 4 in the stop recess 20 of the shift sleeve 5 changes with respect to the axial length of the synchronizer compared to conventional synchronizers without stop 19th Nothing. Due to the axial stop position of the shift sleeve 5 in the uncoupling position of the clutch, the axial displacement position of the shift fork 8 is structurally predetermined for this uncoupling position, without the need for additional measures.
    According to the embodiment of FIG. 1, three stops 19 are arranged uniformly distributed around the circumference of the hub 4. The arrangement is made such that the stops 19 come to rest between the three pressure pieces 18 for the axial loading of the synchronizer ring 11, so that rotationally symmetrical support conditions for the selector sleeve 5 result without impairing the function of the lock synchronization.
    The stops 19 can be mitgeformt in an advantageous manner in a powder metallurgical production of the hub 4, which allows particularly simple production conditions without reworking the hub 4 with respect to the stops 19 6. In a comparable manner, the stop recesses 20 of the shift sleeve 20 in the powder metallurgical production of the shift sleeve 5 can be taken into account.
