Synchronizing ring limits by cone structure and boss structure restriction retrains part degrees of freedom, and the mobile space making progress in axial and footpath is little.
The inner conical surface of described cone structure is provided with worm structure, for destroying the oil film on the synchronous conical surface of reverse gear tooth assembly, increasing friction force.
The inner side of described cone structure arranges some with the equally distributed oil groove of hoop, for synchronizing process, will destroy the lubricated and cooling that increases this position when the lubricant oil producing after oil film is discharged and gearbox turns round.
The utility model relates to a kind of speed changer and switches a grade synchronizer, comprise: reverse gear shaft, reverse gear tooth assembly, reverse gear Toothless synchronizing ring as above and reversing-gear synchronizer assembly, wherein: reverse gear tooth assembly is arranged on reverse gear shaft and with reverse gear Toothless synchronizing ring and matches, the setting of reversing-gear synchronizer assembly with on reverse gear shaft and with reverse gear Toothless synchronizing ring, match.
Described reversing-gear synchronizer assembly comprises: tooth cover, slide block, wherein: tooth cover inner side arranges groove, and this groove matches with slide block, when entering grade, the Mei Jiao of tooth cover contacts with reverse gear tooth assembly, and slide block matches with the position structure of reverse gear Toothless synchronizing ring.
Described reverse gear tooth assembly comprises: in conjunction with tooth, synchronous cone, wherein: synchronous cone matches with the cone structure of reverse gear Toothless synchronizing ring, when entering grade, in conjunction with tooth, contacts with reversing-gear synchronizer assembly.
When the operating mechanism on gearbox promotes the tooth cover of reversing-gear synchronizer assembly by reverse speed fork, tooth cover enters a grade direction by inner groove design band movable slider to reverse gear and moves, slide block contacts and pushes reverse gear Toothless synchronizing ring to reverse gear tooth assembly with boss structure in reverse gear Toothless synchronizing ring, now the male cone (strobilus masculinus) of the synchronous cone on the cone structure of reverse gear Toothless synchronizing ring and reverse gear tooth assembly is fitted and is followed certain pressure to produce friction, namely synchronous effect; Tooth cover continues to move to entering a grade direction, and the combination tooth contact of crossing on reverse gear Toothless synchronizing ring and reverse gear tooth assembly files, and synchronizing process completes.
It is large and follow the defect of step sense that the utility model has also solved common reverse gear synchronous mechanism berth-changing strength when reverse gear engage a gear when realizing reversing-gear synchronizer function, promotes the property of automatic shft of whole gearbox.
