Definitions
- the invention relates to a transmitter for a synchronization assembly of a gearbox.
- the synchronization assembly In manual transmissions, as used in particular in motor vehicles, the synchronization assembly is used to produce a rotationally fixed connection between a transmission shaft and a gear arranged as a loose gear on the gear or gear. In a first step of the switching operation, the synchronization assembly ensures that the speed of the gear wheel to be switched is adjusted to the speed of the transmission shaft. In a second step, a rotationally fixed connection between the transmission shaft and the gear wheel is then produced. The corresponding gear is then switched.
- Synchronization assemblies which have as essential components a synchronizer hub, received therein plungers, synchronizer rings and a shift sleeve.
- a synchronizer hub received therein plungers, synchronizer rings and a shift sleeve.
- one of the synchronizer rings is pressed over the plungers against a friction surface which is assigned to the gear wheel to be switched.

- the synchronizer ring provides the necessary speed adjustment between the gear shaft and the gear wheel before the rotationally fixed connection between the gear shaft and the gear wheel is made.
- the pressure piece ensures the so-called pre-synchronization and fixes the synchronizer ring in a neutral position, so that undesirable drag torques are reduced or eliminated.
- the synchronizer ring is provided with at least one driver on which a blocking surface is formed, which can cooperate in the circumferential direction with the transmitter.
- the lock function is integrated into the synchronizer ring, which prevents a through-connection of the transmitter, as long as the speeds of the gear wheel and the gear shaft are not yet synchronized.
- the synchronizer ring is provided with at least one Vorsynchronisierschräge at which the pressure piece can act under the action of the spring.
- the Vorsynchronisierschräge causes the fixation of the synchronizer ring in a neutral position, but at the same time allows the switching of the transmitter by pushing the pressure piece against the action of the spring, when the transmitter is turned on. It is preferably provided that the Vorsynchronisierschräge is formed on the driver. This results in a very compact design.
- the pressure piece is guided in the circumferential direction and in the axial direction in the transmitter. This too leads to a compact construction of the transmitter.
- the pressure piece is arranged in a recess which inwardly in the radial direction is opened, and that the spring is supported on an abutment, which is carried out separately from the transmitter.
- An inward in the radial direction, ie towards the central axis of the gear shaft, opened transmitter facilitates the mounting of the pressure piece in the transmitter.
- the abutment is a clip which is mounted on the transmitter. The clip can be closed in a technically simple manner, the opening in the transmitter and at the same time the abutment for the spring are formed.
- the abutment is a retaining ring which is inserted into the transmitter.

- This configuration is characterized by a simple structure, low drag torque due to the axial coupling of the synchronizer rings, a small space requirement and easy installation.
- at least one connecting tab may be provided on each of the synchronizing rings, by means of which the two synchronizing rings are positively connected with each other. This facilitates the Pre-assembly of the synchronizer rings on the transmitter, since the connecting straps can be inserted through connection openings of the Transmitted.
- the two synchronizer rings are positively connected with each other, they can no longer be released by the transmitter.
- the two synchronizer rings are rotatably mounted on the transmitter in the circumferential direction, that they have two oppositely arranged driver, on each of which two locking surfaces are provided, and that the pressure member presses apart the two drivers in the circumferential direction, so that the two Driver in opposite directions abut the transmitter.

- the basic structure of a synchronization assembly for a manual transmission is described below with reference to FIGS. 1 to 8, wherein a transmitter according to a first embodiment is used in the synchronization assembly.
- the transmission includes a transmission shaft 10 on which two gear wheels 12, 14 are arranged.
- the two gear wheels 12, 14 are designed as loose wheels, so they can rotate relative to the gear shaft. Rotationally connected to each gear wheel 12, 14 a coupling toothing 16 is connected.
- a transmitter 18 is arranged, which is formed here by a transmitter disk 20 and two clutch plates 22.
- the two clutch plates 22 are arranged on one and the other side of the transmitter disk 20 and have an external toothing 24 and an internal toothing 26.
- the external toothing 24 is designed to be complementary to the coupling toothing 16, and the internal toothing 26 is in engagement with a gear shaft toothing 28.
- the clutch plates 22 are rotatably coupled in the circumferential direction with the transmission shaft 10, but can be moved in the axial direction on the transmission shaft.
- a synchronizer ring 30 is arranged, which can cooperate with a friction surface 32, which is assigned to the corresponding gear wheel 12 and 14 respectively.
- the two synchronizer rings have a plurality of drivers 34 which extend in recesses 36 in the transmitter disk 20, and two diametrically opposite connecting straps 38 which extend through connection openings 40 in the transmitter disk 20 (see in particular FIG. 3).
- the connecting tabs 38 serve to couple the two synchronizer rings in the axial direction with each other. In the coupled state (see Figure 4) are the free ends of the driver 34 of the two synchronizer rings 30 closely opposite each other.
- one of the synchronizer rings is formed with a connecting projection 39 which engages in a connecting opening 41 of the other connecting strap 38.
- a positive connection is obtained at two diametrically opposite points of the two synchronizing rings, which is designed similar to the connection between two pieces of puzzle pieces.
- the two synchronizer rings can be made identical.
- a pocket 37 is formed, in which a pressure piece 42 (see in particular Figures 5 and 6) is arranged, which is acted upon in each case by a spring 44 in the radially outward direction.
- the pressure piece is thus guided in the circumferential direction between the side edges of the pocket 37 and in the axial direction between the two clutch plates 22.
- each pressure piece a Vorsynchronisier Chemistry 46 is formed, which bears against Vorsynchronsierschrägen 48, which are formed at the free ends of the driver 34 on the radially inner side (see Figure 7).
- the pre-synchronizing bevels 48 of the opposing dogs 34 are aligned so that a V is formed with a large opening angle, the tip of which points radially outward.
- On the drivers 34 locking surfaces 50 are formed, seen in the circumferential direction opposite to the edges of the recess 36 obliquely aligned. Again, the blocking surfaces 50 form a V on the opposite drivers 34, wherein the tip of the two V of opposite driver to the center of the recess 36 is directed.
- the synchronizing assembly described operates in the following manner:
- a gear is to be switched, for example, one containing the gear wheel 14, the transmitter 18 is moved in the direction of arrow P of FIG Gear shaft 10 shifted.
- the two synchronizer rings 30 are driven to the left by the pressure pieces 42, more precisely by the pre-synchronizing surface 46 of the pressure piece 42 acting on the left-hand presynchronizing bevel 48 of the left synchronizing ring 30, so that the synchronizer ring 30 frictionally engages with the friction surface 32 passes.
- the rotational speed of the gear shaft 10 does not correspond to the rotational speed of the gear wheels, so that there is a speed difference between the synchronizer ring 30 and the friction surface 32.
- the synchronizer ring is entrained in the circumferential direction (see the arrow U in Figure 8), whereby the locking surface 50 comes into abutment with respect to Figure 8 upper edge of the recess 36. Due to the oblique orientation of the blocking surface 50, a force component is thereby produced which prevents a displacement of the transmitter disk 20 relative to the driver 34; as long as there is a speed difference, the resulting friction torque causes the locking surface 50 remains pressed against the edge of the recess 36.
- the synchronizer ring is supported on the friction surface 32 and can not be moved further in the axial direction. Only when the speed difference is reduced, the force exerted by the blocking surface 50 blocking force decreases, so that the edge of the recess 36 of the transmitter disk 20, the blocking surface 50, due to their oblique orientation, in the circumferential direction opposite to the direction of the arrow U can move, which is a switching of the Transmitter allows. At the same time, the pressure pieces 42 are deflected by the obliquely employed Vorsynchronisierschrägen 48 against the action of the spring 44 down, so suppressed.
- the transmitter can be moved axially so far that the external teeth 24 of the clutch disc 22 in the coupling teeth 16th engages, which is associated with the gear wheel 14. In this way, a rotationally fixed connection between the transmission shaft 10 and the gear wheel 14 to be switched is produced.
- the transmitter 18 is moved back in the opposite direction to its center position, whereby the two synchronizing rings 30 are returned to a middle position. In this, the frictional engagement with the friction surfaces 32 is canceled.
- the particular advantage of the first embodiment is that a simply constructed pressure piece can be used, which is guided in a simple manner between the two clutch plates 22 of the transmitter 18 and in the pocket 37. Further, a transmitter 18 is obtained, on which the synchronizer rings 30 can be pre-assembled in a simple manner.
- the pressure piece 42 holds it in a middle position on the transmitter disk 20, in which the positive locking design on the two connection tabs 38 are within the connection openings 40 so that they can not come apart.
- a transmitter according to a second embodiment of the invention will now be described with reference to FIGS. 9 to 12.
- the same reference numerals are used, and reference is made in this regard to the preceding explanations.
- each synchronizer ring 30 is not fixedly coupled together in the axial direction, but are displaceable relative to each other.
- Each synchronizer ring has four drivers 34, which interact in pairs. For this purpose, they extend through the recess 36 of the transmitter disk 20 of the transmitter 18 therethrough.
- the pressure piece 42 is arranged, which is acted upon by the spring 44 radially outward.
- the pressure piece 42 is executed rounded, so that the tip of the pressure piece is located between the two drivers 34 and this presses apart in opposite directions (see the arrows P in Figure 10).
- each driver 34 which is against the edge of Recess 36 is pressed, is provided with the two locking surfaces 50, which are arranged obliquely adjacent to each other, so that a pointed V is formed.
- the two synchronizing rings 30 are fixed in the initial position of the transmitter at this fact that the two locking surfaces 50 of the total of four drivers 34 of each synchronizer ring are pressed against the edge of the recess 36.
- the transmitter When the transmitter is actuated to shift a gear, it takes over the locking surfaces 50 directly with the two synchronizer rings 30, until one of them impinges on its associated friction surface 32. Due to the speed difference between the gear shaft and the gear wheel to be switched a friction torque is generated, which seeks to rotate the corresponding synchronizer ring 30 relative to the transmitter disk 20 of the transmitter 18 that its V-shaped recess between the two locking surfaces 50 fixed against the edge of the recess 36 is pressed. In this way, a blocking effect is generated, which prevents the switching of the transmitter, as long as the rotational speeds of the gear shaft and the gear wheel are not synchronized.
- the friction torque acts in the same direction as the driver of the synchronizer rings abut against the locking surfaces. That the switching forces are initiated directly via the blocking surfaces and the drivers of the active synchronizer ring.
- the friction torque acts in the opposite direction.
- the drivers of the active synchronizer ring are rotated against the passive synchronizer ring.
- the pressure piece is displaced to the inside, wherein the switching forces are introduced via the drivers of the passive synchronizer ring in the active synchronizer ring. That The blocking function is thus ensured by the drivers of the passive synchronizing ring.
- the transmitter disc 20 Only when friction torque is no longer present, the transmitter disc 20, the corresponding synchronizer ring 30 via the locking surface 50 to twist something, so that the edge of the recess 36 is released from the two locking surfaces 50 and can slide in the axial direction on the driver 34.
- the two synchronizer rings 30 are relative rotated to each other so that one of the two arranged in a recess 36 driver is approximated to the other driver.
- the pressure piece 42 is displaced elastically downwards against the action of the spring 44.
- the transmitter disk 20 reaches into the region of a release bevel 60 which, viewed in the axial direction, is arranged on one and the other side of the two blocking surfaces 50.
- FIGS. A third embodiment is shown in FIGS.
- the same reference numerals are used, and reference is made to the above explanations in this respect.
- the third embodiment differs from the first two embodiments in terms of the configuration of the recess 36 for receiving the pressure pieces 42.
- the recess 36 is designed to be radially inwardly open.
- the recess in the transmitter has no "bottom" on which the spring 44 could be supported, instead an abutment is provided, which here is formed by a clip 80.
- the clip is supported by its two outer edges which act as latching shoulders are formed on the transmitter 18, so that the recess 36 is closed radially inwardly.
- the spring 44 is supported, wherein a spring mandrel 81 is provided on the clip 80 for fixing the spring.
- FIGS. 17 to 19 show a fourth embodiment.
- the same reference numerals are used, and reference is made to the above explanations in this respect.
- the fourth embodiment differs from the third embodiment in that the abutment for the spring 44 is formed by a retaining ring 82 which extends circumferentially along the outer edge of the inner opening of the transmitter and against which the springs 44 abut. This also makes it possible to mount the pressure pieces 42 in a simple manner in the transmitter 18. For assembly reasons, the retaining ring 82 is preferably designed so that it rests elastically on the outer edge of the inner opening.
- a fifth embodiment is shown.
- the fifth embodiment differs from the fourth embodiment in that the springs 44 are replaced by a spring ring 84, which bears elastically on the outer edge of the inner opening of the transmitter.
- the plungers 42 are based directly.
- a free space for the transmission shaft is provided radially within the spring ring 84, which allows compression of the spring ring 84.
- a sixth embodiment is shown.
- the third embodiment is similar to the previous embodiments in that the two synchronizer rings 30 are coupled together in the axial direction.
- the pressure piece is used here.
- One of the two synchronizer rings 30 is provided with six drivers 34, which are associated with each other in pairs. Between the mutually associated drivers 34, a receptacle 70 is formed, in which a holding pot 72 can be hung so that it is fixed in the axial direction. For this purpose, the receptacle 70 is executed undercut in the axial direction.
- the holding pot 72 is made of sheet metal and has a recess in which the spring 44 can be mounted together with the pressure piece 42. The pressure piece 42 is thereby guided in the holding pot 72. On its underside, the pressure piece 42 is provided with a snap hook 74, with which it can be fixed captive in a hole in the bottom of the holding pot 72.
- the second synchronizer ring 30 is provided with three connection tabs 38 each provided with an opening 76.
- three holding pots are first suspended in the three receptacles 70 of the synchronizer ring provided with the drivers 34.
- the second synchronizer ring is arranged on the first that its connecting straps 38 come to lie between each two associated drivers 34; the holding pot 72 is designed with bent holder edges, so that the drivers 34 and the connecting straps 38 can be arranged on the same diameter.
- the pressure piece 42 and the spring 44 are inserted into the holding pot 72, so that the pressure piece 42 comes to rest within the opening 76.
- the two synchronizer rings 30 are coupled to each other both in the axial direction and in the circumferential direction.
- the Vorsynchronisierschrägen 48 are formed on the pressure piece 42 in the third embodiment, which thus cooperate in the radial direction with the edge of the recess 36 in the transmitter disk 20.
- the blocking surfaces 50 are arranged in the third embodiment in the same manner as in the second embodiment, that is, each other V-shaped opposite to the outer sides of the driver 34th When a gear is to be shifted, the transmitter is displaced in the axial direction. He takes on one of the Vorsynchronisierschrägen 48, the two synchronizer rings 30 so that one of them with the corresponding friction surface 32 engages.
- a speed difference between the gear shaft and the gear wheel to be switched ensures that the assembly formed from the two synchronizer rings is acted upon in the circumferential direction, whereby the V-shaped notch between the two opposing locking surfaces 50 is pressed against the edge of the recess 36.
- a switching of the transmitter is prevented as long as a friction torque acts on the corresponding synchronizer ring. Only when the speed difference has been eliminated, the transmitter succeeds to slightly turn back the synchronizer ring via the obliquely oriented blocking surface 50, so that the transmitter can be switched through.
