Description
Technical field
The utility model relates to a kind of central ring for automobile synchronizer.
Background technique
Central ring is provided with at present in the speed changer of automobile, but the position degree of relative inner conical surface is excessive between multiple double wedges of common central ring, interior surface of contact is when contacting, because initial velocity is different, and precision controlling easily has problems in process of production, cause laminating degree not tight, the frictional force of surface of contact can only become large along with pressure, Long-Time Service surface abrasion is very serious, and cause double wedge and the gear hole matched unbalance stress in contact process, easily cause indivedual double wedge stressed excessive and rupture, whole synchronizer was lost efficacy.
Model utility content
The technical problems to be solved in the utility model is: for solving above-mentioned Problems existing, a kind of central ring for automobile synchronizer is provided, solve the central ring of general-utility car synchronizer easily because inner side surface precision problem, cause laminating degree not tight, frictional force can only be promoted by pressure at both sides, and easily cause between double wedge because the problem of unbalance stress fracture.
The utility model solves the technological scheme that its technical problem adopts: a kind of central ring for automobile synchronizer, comprise ring body, ring body upper end has six protruding work teeth, work tooth is evenly distributed on ring body upper end, ring body upper end is positioned at work tooth both sides and is provided with transition angle for transition, the nearly upper-end surface of ring body madial wall is provided with for ramp convenient for assembly, nearly lower end surface is provided with for lower inclined plane ring body madial wall, ring body inside offers annular through-hole, ramp offers the annular slotted be connected with through hole, through hole internal fixtion is connected with the ring-shaped speed-increasing circle for promoting ring body assembling laminating degree.
Further, in order to promote the stability of central ring, very close to each other between magnet outer surface and through-hole wall.
Further, in order to promote uniform force degree, the angle of work tooth between operated adjacent tooth is 60 °.
Further, conveniently coordinate, work transverse tooth thickness degree diminishes from top to bottom gradually.
The beneficial effects of the utility model are, a kind of central ring for automobile synchronizer of the present utility model by arranging the larger speedup ring of skin friction on the mating face of inner side, facilitate Oil Guide, thus greatly promote whole central ring and the synchronized efficiency of other mounting ring, reduce the impact to work tooth surface, thus make central ring stressed more even in running, greatly increase the service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is detailed drawing of the present utility model.
1. ring bodies in figure, 2. work tooth, 3. transition angle, 4. ramp, 5. lower inclined plane, 6. through hole, 7. slots, 8. magnet.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Fig. 1, a kind of central ring for automobile synchronizer shown in Fig. 2 and Fig. 3, comprise ring body 1, ring body 1 upper end has six protruding work teeth 2, work tooth 2 is evenly distributed on ring body 1 upper end, ring body 1 upper end is positioned at work tooth 2 both sides and is provided with transition angle 3 for transition, the tooth 2 that wherein works adopts forming cutter to process, the size this ensures that thering each work tooth 2 processed is identical, because forming cutter has transition angle 3 in tooth process processed, therefore the transition at transition angle 3 can be formed in the bottom of each work tooth 2, the stress that transition angle 3 reduces root is concentrated, thus eliminate the breakage problem of work tooth 2, improve the reliability of product, the nearly upper-end surface of ring body 1 madial wall is provided with for ramp 4 convenient for assembly, the nearly lower end surface of ring body 1 madial wall is provided with for lower inclined plane 5, ring body 1 inside offers annular through-hole 6, ramp 4 offers the annular slotted 7 be connected with through hole 6, through hole 6 internal fixtion is connected with the ring-shaped speed-increasing circle 8 assembling laminating degree for promoting ring body 1, ring-shaped speed-increasing circle 8 is abrasive rubber material, ring-shaped speed-increasing circle 8 inner diameter is less than ring body 1 inner diameter.
Further, in order to promote the stability of central ring, very close to each other between magnet 8 outer surface and through hole 6 inwall, further, in order to promote uniform force degree, the angle of work tooth 2 between operated adjacent tooth 2 is 60 °, further, conveniently coordinate, work tooth 2 thickness diminishes from top to bottom gradually, a kind of central ring for automobile synchronizer of the present utility model by arranging the larger speedup ring 8 of skin friction on the mating face of inner side, facilitate Oil Guide, thus greatly promote whole central ring and the synchronized efficiency of other mounting ring, reduce the impact to work tooth 2 surface, thus make central ring stressed more even in running, greatly increase the service life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
