Abstract
This utility model is related to a kind of Novel end face tooth flanged yoke structure, and the flanged yoke is provided with two ears being symmetric, and offers earhole, be provided with reinforcement at the base wells of ear in the ear, and the reinforcement is combined together with ear, flanged yoke body；It is located on the flanged yoke body below the ear and offers four spot-facings being symmetric, spot-facing direction is in 90 ° of angle shapes with earhole centrage；The spot-facing periphery is black skin fillet；It is middle pan portion between two spot-facings of described Liang Ge ears homonymy, pan portion of the middle pan portion for recess；This utility model improves the torsional fatigue life of driving-shaft assembly, solves the quality problems of original structure flanged yoke fatigue fracture, interferes with flanged yoke card when solving the problems, such as that wrest fixing spanner rotates.
Description
Technical field
This utility model belongs to flanged yoke technical field, more particularly to a kind of Novel end face tooth flanged yoke structure.
Background technology
The flanged yoke at heavy-duty commercial vehicle power transmission shaft two ends is typically all to use end face tooth type flanged yoke, the end face tooth type flange
The structure of fork is as shown in figure 1, its shortcoming is：1st, nearby black skin fillet is less for existing end-tooth flanged yoke spot-facing, spot-facing side
To being in 55 degree of fixtures with flanged yoke earhole centrage, very close to ear's black skin near spot-facing, cause stress concentration herein, drop
Low flanged yoke torsional fatigue life.2nd, spot-facing depth has 3-5mm, the card surplus in the middle of two spot-facings of two ear the same sides
Higher, when nut Tightening moment is checked, torque spanner may be blocked by intermediate panel, cause main engine plants tight in detection nut
Gu complain during torque.3rd, it is loss of weight, two ear bottom portions are also dug up by flanged yoke base wells, it reduce the entirety of flanged yoke
Rigidity, and the stress near the spot-facing of pan portion front at blank fillet is further increased, reduce flanged yoke torsional fatigue life.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of Novel end face tooth flanged yoke
Structure, solves the problems, such as that flanged yoke torsional fatigue life is not enough, and interference problem during torque spanner torsion, improves flanged yoke and turns round
Turn fatigue life, it is ensured that the fatigue of car load demand is reached using the fatigue life of the heavy duty transmission axle assembly of this end-tooth flanged yoke
Life-span, and avoid interfering problem during torque spanner detection nut Tightening moment.
By following technical solution completing, the flanged yoke is provided with two and is symmetric the purpose of this utility model
Ear, offer earhole in the ear, at the base wells of ear, be provided with reinforcement, the reinforcement and ear, flanged yoke sheet
Body combines together；Be located on the flanged yoke body below the ear and offer four spot-facings being symmetric, spot-facing direction with
Earhole centrage is in 90 ° of angle shapes；The spot-facing periphery is black skin fillet.
Preferably, being middle pan portion between two spot-facings of described Liang Ge ears homonymy, the middle pan portion is depression
The pan portion of shape.
The beneficial effects of the utility model are：Prove through torsional fatigue test, be mounted with the power transmission shaft of this novel flange fork
Assembly, on fatigue life, than improve about 3-4 times using original structure flanged yoke driving-shaft assembly, significant increase power transmission shaft
The torsional fatigue life of assembly；After having used the driving-shaft assembly of novel flange fork to put on market, original structure method is thoroughly solved
The quality problems of blue fork fatigue fracture, greatly reduce the quality costs such as three guarantees after sale；In addition, verify through each main engine plants' entrucking, newly
Interfere with flanged yoke card when type flanged yoke thoroughly solves the problems, such as that wrest fixing spanner rotates.
Description of the drawings
Fig. 1 is existing end-tooth flanged yoke structural representation.
Fig. 2 is end-tooth flanged yoke structural representation of the present utility model.
Label in accompanying drawing is respectively：1st, flanged yoke；11st, ear；12nd, earhole；13rd, reinforcement；14th, spot-facing；15th, blank
Face fillet；16th, middle pan portion.
Specific embodiment
Detailed introduction is done to this utility model below in conjunction with accompanying drawing：As shown in Figure 2, the flanged yoke 1 is provided with two
The ear 11 being symmetric, offers earhole 12 in the ear 11, is provided with reinforcement 13 at the base wells of ear 11, should add
Strong muscle 13 is combined together with ear 11, flanged yoke body；On the flanged yoke body below the ear 11 offering four is in
Symmetrical spot-facing 14,14 direction of spot-facing are in 90 ° of angle shapes with 12 centrage of earhole；14 periphery of spot-facing is black skin circle
Angle 15.
It is middle pan portion 16 between two spot-facings 14 of described 11 homonymy of Liang Ge ears, the middle pan portion 16 is recess
Pan portion.
Compared with former technical scheme, innovative point is this utility model：1,15 diameter of black skin fillet nearby of spot-facing 14 is increased,
Distance between 11 blank column face of spot-facing 14 and ear is increased, 14 depth of spot-facing is reduced, in two ears 11 in 14 direction of adjustment spot-facing
Increase reinforcement 13 at base wells, reduce flanged yoke spot-facing stress nearby with these measures, the flanged yoke fatigue longevity is greatly improved
Life；2, the upper surface of the middle pan portion 16 of two spot-facings 14 of two ears, 11 homonymy toward lower recess, make such structure ream again
Behind hole 14, two spot-facings 14 become raised in middle side, solve the problems, such as wrest fixing spanner rotational interference.
This utility model is not limited to above-mentioned embodiment, no matter constitute in its shape or material making any change, all
It is using structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
