Abstract
The utility model discloses an automobile synchronization regulator, and relates to the technical field of automobile manufacturing. The automobile synchronization regulator comprises a gear sleeve, a gear hub provided with a sliding block groove, a combination gear provided with a cone, and a synchronizing ring provided with a conical bore. The gear sleeve and the gear hub are sleeved with each other in a connected mode. The outer edge of the gear hub is provided with a plurality of slide blocks. The gear hub is connected with the sliding blocks in a clamped mode through the sliding block groove. The combination gear extends into the conical bore of the synchronizing ring through the cone. The synchronizing ring and the combination gear are sequentially sleeved with the gear sleeve in a connected mode on one side of the gear hub. The outer edge of the synchronizing ring is provided with a plurality of positioning bosses. The side, close to the synchronizing ring, of each sliding block is provided with a clamping foot which extends out of the side face of the sliding block.

Compared with the prior art, the automobile synchronization regulator is used in a gearshift device which has five gear positions and puts into gear in one direction. When the automobile synchronization regulator is in a neutral gear state, the position of the synchronizing ring is limited, the connecting surface of the synchronizing ring and the connecting surface of the combination gear are separated completely, and the phenomena of 'rotation caused by a neutral gear' and an abnormal sound caused by the movement of the synchronizing ring are avoided.
Description
Technical field
The utility model relates to field of automobile, especially a kind of synchronizer for manual gear of vehicle.
Background technique
Automobile synchronizer is a kind of mechanical device of realizing the automobile balance gearshift.In conventional gear box, mesh smoothly in order to make meshed gears reach consistent rotating speed, realize smooth-going, shock-free gear shift operation, adopt synchronizer to realize gear shift operation more.Such as Chinese invention patent " synchronizer with Anti-extrusion integrated slider " (patent publication No.: CN101655140A, open day: on February 24th, 2010), this patent discloses a kind of synchronizer with Anti-extrusion integrated slider, this synchronizer with Anti-extrusion integrated slider includes the tooth cover, be provided with the tooth hub of slide block slot, be provided with cone in conjunction with tooth, be provided with the synchronizing ring of conical bore; Wherein, described tooth cover and described tooth hub socket-connect, and described tooth hub outer is provided with a plurality of slide blocks, and described tooth hub is by its slide block slot and the clamping of described slide block phase; Describedly stretch in the conical bore of described synchronizing ring two groups of described synchronizing ring and describedly be socketed in successively described tooth cover both sides in conjunction with tooth by its cone in conjunction with tooth; Described tooth hub is provided with the synchronous rotating chamfered groove of alternately arranging with slide block slot, and described synchronizing ring is provided with synchronous corner boss.In use there are the following problems for this automobile synchronizer:
1, this synchronizer is as in the unidirectional gearshift of putting into gear that is used in five gears and puts, and when synchronizer is in when moving back the gear state, the tooth cover is moving toward the neutral displacement vertically, slide block is along with the tooth cover moves axially together, unclamp synchronizing ring, gapped between slide block and the synchronizing ring at this moment, synchronizing ring easily produces play; Or synchronizing ring because of its conical bore with produce bonding in conjunction with the junction surface of tooth cone, cause abnormal sound or " the neutral band turns " phenomenon; Because synchronizing ring is play in conjunction with the cone of tooth for a long time, synchronizing ring premature wear failure phenomenon easily occurs;
When 2, assembling, first synchronizing ring is installed on the axle, then press-fit the tooth hub with press machine, the synchronous corner boss on the synchronizing ring stretches into the synchronous rotating chamfered groove of tooth hub, the phenomenon of synchronizing ring easily occurs damaging by pressure because the synchronous rotating chamfered groove of tooth hub does not aim at the synchronous corner lug boss position on the synchronizing ring.
The model utility content
Technical problem to be solved in the utility model provides a kind of automobile synchronizer, this automobile synchronizer can carry out spacing to synchronizing ring, be used in the unidirectional gearshift of putting into gear that five gears put, the abnormal sound that synchronizing ring play in conjunction with the cone of tooth causes in the time of can preventing the retaining gear and synchronizing ring are because of its conical bore and the problem that produces bonding in conjunction with the junction surface of tooth cone.
In order to address the above problem, the technical solution adopted in the utility model is: this automobile synchronizer, include the tooth cover, be provided with the tooth hub of slide block slot, be provided with cone in conjunction with tooth, be provided with the synchronizing ring of conical bore; Described tooth cover and described tooth hub socket-connect, and described tooth hub outer is provided with a plurality of slide blocks, and described tooth hub is by its slide block slot and the clamping of described slide block phase; Describedly stretch in the described conical bore of described synchronizing ring by its cone in conjunction with tooth, be provided with successively the described synchronizing ring that socket-connects with described tooth cover and described in conjunction with tooth in a side of described tooth hub, described synchronizing ring outer is provided with a plurality of positioning boss, one side of the nearly described synchronizing ring of described slide block is provided with the card base that stretches out its side, described card base and the clamping of described positioning boss phase; Opposite side at described tooth hub is provided with slide block rib and tooth cover rib.
In the above-mentioned automobile synchronizer technological scheme, technological scheme can also be more specifically: institute's card base is provided with opening towards radially inside draw-in groove.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the slide block of automobile synchronizer is provided with card base, the positioning boss phase clamping of card base and synchronizing ring, and slide block is simultaneously and tooth hub and the clamping of synchronizing ring phase.When moving back gear, the tooth cover is moving toward the neutral displacement vertically, slide block is along with the tooth cover is mobile together, when slide block is prepared to get back to the neutral position, the card base of slide block is withdrawn into tooth hub end face with synchronizing ring, and synchronizing ring is pressed on the tooth hub end face, limit position to synchronizing ring, the slide block rib of tooth hub and tooth cover rib has limited the position of slide block and tooth cover simultaneously, make synchronizing ring and separate fully in conjunction with the tooth junction surface, avoid occurring " the neutral band turns " and synchronizing ring play and the abnormal sound and the early stage wear out failure phenomenon that cause in conjunction with the cone of tooth;
2, synchronizing ring is produced and is adopted extrusion process, but the die sinking once-through of axial direction both sides; Shooting Technique is adopted in slide block production, but also once-through of radial direction die sinking; Because die casting and Shooting Technique all are ripe at present production technologies, low cost of manufacture.First with slide block and tooth hub and the clamping of synchronizing ring phase, be loaded on the tooth cover during assembling, then as an integral press mounting to axle, avoid occurring damaging by pressure the phenomenon of synchronizing ring.
