る。As is conventionally well known, in the inertia lock type synchronization mechanism, as the sleeve moves, the inner teeth of the sleeve first come into contact with the outer teeth of the synchronizer ring and act synchronously, and then, after the synchronization is completed, the inner teeth of the sleeve While meshing with the external teeth of the synchronizer ring, it moves further and meshes with the gear dog, forming an integral spline connection. Therefore, the movement stroke of the sleeve is up to the final gear dog, and the shift amount of the change lever is also relatively large in accordance with this sleeve stroke. In addition, since the chamfer of the sleeve internal teeth engages with both the synchronizer ring and gear dog when meshing,
There are problems such as easy damage. Regarding shortening the shift amount of this type of synchronization mechanism,
There is a prior art, for example, Japanese Utility Model Publication No. 54-36207, which uses an insert and a synchronizer ring to perform a synchronous action, which is different from the present invention, which is based on the premise that a sleeve and a synchronizer ring perform a synchronous action.

シャロック型同期機構を提供Ｊることを目的とする。In view of the above-mentioned problems in the prior art, the present invention shortens the movement stroke of the sleeve in a system in which the sleeve and the synchronizer ring act synchronously, and after the synchronization is completed, the sleeve is engaged with the gear dog. An object of the present invention is to provide an inertia lock type synchronization mechanism that reduces damage to a chuck 1 on the sleeve side.

のである。For this purpose, the configuration of the present invention is such that teeth with chamfers for synchronization and teeth with chamfers for power transmission are provided separately on the sleeve side, and teeth for power transmission are provided separately compared to periodic teeth. By forming long teeth, the synchronization and power transmission teeth mesh with the synchronizer ring and gear dog almost simultaneously after synchronization is completed, eliminating the need for the time required for the sleeve to mesh with the gear dog. This is a summary.

するように構成することもできる。Hereinafter, the present invention will be specifically explained based on the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a synchronizing mechanism, in which a sleeve 4 is spline-fitted to the outside of a hub 3 spline-coupled to a rotating shaft 2 so as to be movable in the axial direction.
A key 5 is provided between several grooves 3a on the outer periphery of the hub 3 and a groove 4a on the sleeve 4 side, and a key spring 6 is biased to this key 5. Also, the cone portion 7a of the gear 7
A synchronizer ring 8 is fitted into the ring 8, and a gear dog 9 is integrally formed on the gear 7 on the opposite side of the ring 8 from the sleeve 4. Therefore, in the above structure, two @4b and 40 are formed in two layers on the inner peripheral part of the sleeve 4, and the inner teeth 4b and 40 are formed in two layers.
is for synchronization and is relatively short and has a dedicated chamfer 4b' at the tip, and the outer tooth 4C is for power transmission and is longer than the tooth 4b and has a similar dedicated chamfer 4C- at the tip. On the other hand, in the synchronizer ring 8, teeth 8a are formed at the same height as m4b on the inner side that does not interfere with the outer @4G, and this tNJ8a has a chamfer 8a- that contacts the chamfer 4b', and the gear dog 9 has Chamfa 98
A tooth 9a having a radial diameter 9a is formed at the same height as the tooth 4C. Next, the operation of the synchronization mechanism configured in this way will be explained. First, when the sleeve 4 is moved in the axial direction with a shift operation, the key 5 presses the synchronizer ring 8 against the cone portion 1a of the gear γ, and synchronization starts. Then sleeve 4
When the key 5 is pressed down and moved further, the synchronization tooth 4b chuck? 4b' contacts the chamfer 8a' of the tooth 8a of the synchronizer ring 8 in a misaligned manner and strongly presses against each other, thereby transmitting the rotation of the sleeve 4 to the gear A77 side and synchronizing the two rotations so that they are equal. At this time, as shown in FIG. 2, the chamfer 40' of the long tooth 4C on the sleeve 4 side is in a position with a slight gap δ from the chamfer 9a of the tooth 9a of the gear dog 9. Therefore, the above-mentioned synchronizing action is completed and the teeth 4b of the sleeve 4
At approximately the same time that @4C meshes with 8a of the synchronizer ring 8, @4C also meshes with the teeth 9a of the gear dog 9, so that the sleeve 4 and the gear 7 are integrally connected, and the rotation of the gear 7 is transmitted to the rotating shaft 2. In this way, the two teeth 4 formed on the sleeve 4
One of b and 4c engages only with the synchronizer ring 8 and acts in synchronization, and the other engages only with the gear dog 9 and acts to transmit power. In addition, in the above embodiment, the two teeth 4b of the sleeve 4. 4C are provided with their heights shifted in the radial direction, but they may be provided separately and shifted in the circumferential direction, and in that case, they may be configured to mesh and operate independently with the synchronizer ring 8 and gear dog 9. can.

少ない。As is clear from the above embodiments, according to the present invention, in the synchronization mechanism, two teeth jb and 4c for synchronization and power transmission are formed separately on the sleeve 4, and after the synchronization is completed, the two teeth ab, 4c meshes with the synchronizer ring 8 and gear dog 9 at almost the same time, hX, etc., and the movement stroke of the sleeve 4 is approximately just enough for the tooth 4b to mesh with the synchronizer ring 8, and compared to the conventional case, the gear dog 9
Since the stroke is shortened by the amount of meshing stroke, operability is improved. In addition, since the teeth 4b and 4c of the sleeve 4 mesh with each other separately, there is little damage to the chamfers 4b' and 4cm.
