Description
Technical field
The utility model relates to the fields of universal joint, and in particular to a kind of Novel bolt universal-joint.
Background technique
Existing universal joint assembly is generally circlip with transmission shaft fork connection scheme and fixes, and universal joint bearing bowl is circle,
It is interference fitted with transmission shaft fork hole, it is axial to use circlip clamping, according to circlip position difference, it is divided into inner blocking type, external clamping type two
Kind.The connection type of this scheme assembly when, cross axle needs be set in entry in advance, then will be pre-assembled needle roller,
The bearing of the attachmentes such as oil sealing is pressed into entry on the outside of entry, finally assembles circlip.
Prior art transmission shaft fork part shape is more complex, all acquires a certain degree of difficulty from processing is swaged to.Assembly step
It is rapid also relatively complicated, it needs to be pressed by press machine, also needs assembly circlip.Union piece is more, and total weight is larger, leads
It causes entire rotational inertia of transmission system big, vehicle NVH, oil consumption etc. is all adversely affected.In addition prior art assembly ten thousand
To needing for cross axle to be set in entry in advance when saving, this just has restriction to entry and the mutual size of cross axle, for cross
Axis can smoothly be packed into section entry, and section fork generally requires to cut a part, and the part cut causes entry to bearing bowl female surface
Reduce.Bearing bowl is thin-walled parts, and lesser female surface is unfavorable factor.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is universal to provide a kind of Novel bolt connection
Section.
The purpose of this utility model is completed by following technical solution: this Novel bolt universal-joint, main
It to include cross axle, bearing block with holes, dust cover, oil sealing, needle roller retaining ring, needle roller, gasket, cross axle includes four axle journals, often
A set of bearing is assembled on a axle journal, every set bearing is provided with semiclosed cylinder in the middle part of bearing block with holes using bearing block with holes as matrix
Hole, semiclosed cylindrical hole bottom are equipped with gasket, and semiclosed cylindrical hole inner wall circumferencial direction is uniformly arranged whole circle needle roller, semiclosed circle
Post holes oral area is pressed into oil sealing, needle roller retaining ring is placed between oil sealing and needle roller, semiclosed cylinder orifice part periphery is cased with dust cover.
Semiclosed cylindrical hole two sides in the middle part of the bearing block with holes are mounting blocks, are drilled with bolt hole on mounting blocks.
The bolt hole is unthreaded hole or threaded hole.
The semiclosed cylindrical hole is designed as bowl structure, and bowl structure bottom outside is equipped with outer bottom mating surface, bowl-shape knot
Lateral register face there are two being set on the outside of structure.
The lateral register face arranges that two sides can be set to α to positioning surface relative to the axisymmetrical of semiclosed cylindrical hole
=0 ° of parallel plane can also be equipped with certain taper, α < 10 °, convenient for assembly guiding.
The utility model has the following beneficial effects:
1, the utility model simplifies the mounting means of universal joint assembly and transmission shaft, convenient for assembly；Simplify transmission shaft fork
The manufacturing process of part reduces manufacture difficulty；Solve the problems, such as that circlip type universal joint female surface is too small；Reduce transmission system weight
Amount reduces oil consumption so as to improve vehicle NVH performance.
2, the utility model can improve the problems such as traditional circlip type universal joint assembly is inconvenient, and the design only needs to use spiral shell when assembling
Bolt tightens bearing block and section fork, eliminates traditional circlip type universal joint dress fork, press machine pressure circular journal bearing bowl, assembling jump ring etc.
Step.
3, the utility model simplifies transmission shaft fork part manufacturing process, and traditional scheme needs to process round entry, and essence
Degree requires, and jump-ring slot need to be also cut out in hole, it is plane that this programme section, which pitches main machined surface, relatively easy.
4, the utility model thoroughly solves female surface and crosses minor issue, and traditional scheme is due to being related to cross axle dress fork problem, section
Fork more or less needs cut-out, causes female surface insufficient, and this programme is not related to cross axle dress due to changing assembly method
Fork problem may be implemented to contain entirely.
5, the utility model alleviates transmission system weight, improves vehicle NVH performance, oil consumption is reduced, with traditional scheme axis
For holding 57 specification universal joint of bowl outer diameter, after using this programme, entire transmission system weight saving 10kg or more.
