Description
Technical field
This utility model belongs to technical field of automobile parts, relates to a kind of anticreep drive shaft assembly attachment structure。
Background technology
Driving axis is one of vitals of car transmissions, and what employing was maximum at present is ball cage type driving axis, and this kind of drive axle whether circular arc alley or liner ball road solve constant speed drive's problem all preferably, and it is big to transmit operating angle, and efficiency is high。Existing automobile driving axle is all made up of external ball cage and internal spherical cage, the shortcoming of this structure is, bearing capacity is poor, the pavement state of complexity can not be adapted to, decrease the service life of automobile drive axle, in order to increase operating angle, devise double; two external ball cage structure later, however it is necessary that and its attachment structure is improved, to adapt to the needs of double; two external ball cage。
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in construction, and operating angle is big, the anticreep drive shaft assembly attachment structure that bearing capacity is strong。
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: a kind of anticreep drive shaft assembly attachment structure, include cage assembly, described cage assembly includes housing and the steel ball being arranged in housing and retainer, described steel ball is arranged on retainer, it is characterized in that, the left end of described housing has link, the lateral surface of the link of described housing is provided with connection matching spline, the inner side of link is provided with resilient engagement hitch bar, described resilient engagement hitch bar includes elastic connection axle, elastic component and card set part, described elasticity connects axle and is horizontally installed in housing, described elastic component is enclosed within elastic connection on axle。
The measure taked for optimizing such scheme specifically includes:
In above-mentioned a kind of anticreep drive shaft assembly attachment structure, the end position of described link longitudinally offers holding mating groove, described card sets part and is positioned at holding mating groove, described elasticity connection axle offers and sets the inclined-plane breach that part matches with card, drive card to set part by inclined-plane breach when described elasticity connects axle motion and eject or fall。
Compared with prior art, the utility model has the advantage of that whole drive shaft assembly adopts two external ball cages to connect to form and forms, compression long by 662 ± 3 (piston rod is put down with left end cage end face), according to actual needs the link position of external module Yu link can be fixed by resilient engagement hitch bar, ensure that the operating angle of double; two external ball cage, can adapt to the pavement state of complexity, and constant speed drive is effective。
Accompanying drawing explanation
Fig. 1 is this anticreep drive shaft assembly attachment structure schematic diagram。
Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments。
In figure, cage assembly 1；Housing 2；Steel ball 3；Retainer 4；Link 5；Couple matching spline 6；Resilient engagement hitch bar 7；Elastic connection axle 8；Elastic component 9；Card sets part 10；Holding mating groove 11；Inclined-plane breach 12。
As shown in Figure 1, this anticreep drive shaft assembly attachment structure, include cage assembly 1, cage assembly 1 includes housing 2 and the steel ball 3 being arranged in housing 2 and retainer 4, steel ball 3 is arranged on retainer 4, the left end of housing 2 has link 5, the lateral surface of the link 5 of housing 2 is provided with connection matching spline 6, in order to angle when ensureing work is bigger, need exist for the attachment structure on the left side is improved, can be attached overall for external module with link 5 here by coupling matching spline 6, in order to the link position of external module Yu link 5 is fixed, the inner side of link 5 is provided with resilient engagement hitch bar 7, here resilient engagement hitch bar 7 is adopted to be fixed according to actual needs, resilient engagement hitch bar 7 includes elastic connection axle 8, elastic component 9 and card set part 10, the elastic axle 8 that connects is horizontally installed in housing 2, elastic component 9 is enclosed within elastic connection axle 8, end position at link 5 longitudinally offers holding mating groove 11, card sets part 10 and is positioned at holding mating groove 11, elastic connection axle 8 offers and sets the inclined-plane breach 12 that part 10 matches with card, elastic connection axle 8 drives card to set part 10 by inclined-plane breach 12 when moving and ejects or fall, so after external module entirety is connected with the connection matching spline 6 of link 5, the elastic axle 8 that connects makes the elastic axle 8 that connects move under the effect of elastic component 9 elastic force, existence due to inclined-plane breach 12, this scale sets part 10 will along the inclined-plane relative motion of inclined-plane breach 12 thus being converted into and moving upward or move downward, when card sets the connection fixed position just fixing external module and link 5 when part 10 ejects holding mating groove 11。
Adopt the index that the cage of this anticreep drive shaft assembly attachment structure specifically reaches as follows:
(1) assembly parts are without damaging, scratching；Pivot angle rotates with flexible swinging freely, is not allow for catching phenomenon；
(2)；Tired moment of torsion: ± 1000N m, 200,000 circulations；
(3)；The quiet torsion intensity of assembly: >=3000N m；
(4)；Maximum allowable pivot angle: 45 ° of two BJ ends；
(5) compression long by 667 ± 3 (piston rod is put down with left end cage end face)；
(6)；Grease injection 50 ± 5g is added, 70 ± 5g in sheath in fixed knot；Add grease injection 127 ± 10g in telescopic joint, and TJ end leather sheath internal gas pressure is equal to an atmospheric pressure in the position of displacement illustrated dimensions；
(7)；The limit of working temperature of leather sheath and oils and fats :-40 DEG C-120 DEG C, normal working temperature: 80 DEG C
(8)；When joint is in 0 ° and during applying ± 10N m moment of torsion, assembly circumferential clearance≤90 ', assembly BJ end under the axial force of 100N, axial movement value≤0.4mm。
