果となっていたのである。FIG. 6 shows a conventional structure. Conventionally, the axial width t of the synchro hub 1 in which the coupling sleeve 2 is slidably installed is larger than the axial width L of the synchro key 7 fitted in the key fitting groove on the outer periphery of the synchro hub 1. Since it has been constructed, the synchronizing ring 3 is provided with the key groove 12 into which the synchro key 7 is fitted.
When the reinforcement portion 15 is to be provided in the above, the outer diameter R of the synchronization hub 1 must be increased so that the thick portion of the reinforcement portion 15 does not interfere with the synchronization hub 1.
Further, as the outer diameter R of the synchronizing hub 1 becomes larger, the inner diameter of the inner diameter spline 2a of the coupling sleeve 2 also becomes larger. Therefore, the outer diameter of the synchronizing ring 3 having the spline 11 that meshes with the inner diameter spline 2a is inevitably increased. It gets bigger. As described above, the provision of the reinforcing portion on the synchronizing ring has a large effect on the entire synchronizing mechanism.

ハブ１と一体となっている。A rectangular groove deeper than the cross-sectional view spline portion 1a is formed at three equally divided positions on the outer periphery of the synchro hub 1.
Key fitting groove 1b into which the synchro key 7 fits and slides
Has been drilled as. The synchro key 7 fitted in the key fitting groove 1b can also slide in the axial direction of the transmission shaft 29. Then, the spring 1 is biased outward from the inside of the synchro hub 1.
6 is abutted, and the synchro key 7 is pressed in the direction of a key fitting groove formed on the coupling sleeve 2 side. A synchronizing ring 3 having a spline portion 11 that meshes with the inner diameter spline 2a of the coupling sleeve 2 and a key groove 12 into which the synchro key 7 is fitted is fitted around the cone portion 22a of the forward first speed loose fitting gear 22. Also, the sync key 7
The front end of is always fitted in the key groove 12 opened on the rear side surface of the synchronizing ring 3. When the coupling sleeve 2 is in the neutral state, the synchronizing ring 3 is not pressed against the cone portion 22a of the forward first speed loosely fitting gear 22, and is integrated with the synchronizing hub 1 in the loosely fitting state.

First, the coupling sleeve 2 moves together with the synchro key 7 in the direction of the cone portion 22a of the forward first speed loosely fitting gear 22, and the synchro key 7 presses the synchronizing ring 3. Since the synchro key 7 and the synchronizing ring 3 are engaged with each other in the key groove 12, they rotate in the same direction, and the cone portion 3a of the synchronizing ring 3 moves the cone portion 22a of the forward first speed loosely fitting gear 22. Press.

ング３をすり抜けることができない。At that moment, there is a rotation difference between the synchronizing ring 3 and the forward first speed loosely fitting gear 22, so that between the cone portion 3a of the synchronizing ring 3 and the cone portion of the forward third speed loosely fitting gear 4. Then, a frictional force, that is, a cone torque is generated, and the synchronizing ring 3 is pulled by the forward first speed loosely fitting gear 22 and relatively displaced in the rotational direction with respect to the synchro hub 1, the synchro key 7, and the coupling sleeve 2. Occurs, and a balk state is formed by the spline chamfer of the coupling sleeve 2 and the spline chamfer of the synchronizing ring 3. Therefore, in this state, even if an attempt is made to move in the direction of the forward first speed loose fitting gear 22 by the external force applied to the coupling sleeve 2 fork shifter, the coupling sleeve 2 keeps the synchronization ring 3 moving while the cone torque is generated. I can't slip through.

完了する。When the synchronization is completed and there is no difference in rotation between the forward first speed loose fitting gear 22 and the synchronizing ring 3, and the cone torque disappears, the coupling sleeve 2 slips through the synchronizing ring 3 and its inner diameter spline 2a moves forward 1. The quick fit gear 22 is meshed with the spline 22b, and the switching to the first forward speed is completed.

のである。When the connecting sleeve 2 is slid rearward to provide a reverse speed, the sliding of the synchro key 7 when the connecting sleeve 2 slides backward is prevented by the step provided in the reverse speed loose fitting gear 23. This is done by the section 5a.
After the sliding of the synchro key 7 is blocked, the coupling sleeve 2 independently moves rearward to move its inner diameter spline 2a.
Engages with the spline 23a of the reverse speed loosely fitting gear 23, and the switching to the reverse speed is completed. In this way, the reverse side is configured as a color shift clutch without a synchronizing mechanism.

Axial width t of the spline portion 1a on the outer periphery of the synchro hub 1
Is approximately the same as or smaller than the axial width L of the sync key 7. In the synchronizing ring 3, a reinforcing portion 15 as shown in FIG. 3 is formed around the end surface 12a of the key groove 12. End surface 12a of the key groove 12
As is clear from FIG. 2, since the reinforcing portion 15 is located on the side of the synchronizing hub 1, the thick portion of the reinforcing portion 15 should be provided with a sufficient thickness regardless of the outer diameter of the synchronizing hub 1. You can do it. The reinforcing portion 15 may be provided all around the outer circumference of the synchronizing ring 3, but in the present embodiment, it is most rational to form it around the key groove 12 into which the synchro key 7 is fitted.

にまとめることができたのである。Since the present invention is constructed as described above, it has the following effects. That is, the axial width t of the synchro hub in which the coupling sleeve is freely installed only manually is set to be substantially the same as or smaller than the axial width L of the synchro key fitted in the key fitting groove on the outer periphery of the synchro hub. When the reinforcing portion is provided on the synchronizing ring by including the key groove into which the synchro key is fitted, the end face of the key groove is located on the side of the synchro hub, and the thick portion of the reinforcing portion is the synchro hub. It can be provided with a sufficient thickness without any interference. Therefore, even if the synchronizing ring is provided with a reinforcing portion, it is not necessary to increase the outer diameter of the synchronizing hub, and as a result, the entire synchronizing mechanism is substantially the same size as the synchronizing ring having no reinforcing portion. I was able to put together.

向上を合理的に達成することが可能となったのである。Further, since the reinforcing portion provided on the synchronizing ring having the key groove into which the synchronizing key is fitted is formed around the key groove into which the synchronizing key is fitted, the key groove which is most stressed in the synchronizing ring is formed. By strengthening the peripheral part of the ring with the reinforcing part, it was possible to rationally improve the breaking strength of the synchronizing ring.
