Description

A kind of new constant velocity cardan joint internal spline axial fixing structure
Technical field
The present invention relates to universal joint internal spline structure, especially a kind of new constant velocity cardan joint female splined shaft is to fixed knot Structure.
Background technology
In prior art, constant velocity cardan joint internal spline and the cooperation of axostylus axostyle external splines are carried out axially by elastic spring It is fixed, it is ensured that vehicle spline fitted in operation process firmly occurs without situations such as releasing, and the positioning method is primarily present following Problem:1st, after coordinating there is axial gap in inside and outside spline;Axial float and abnormal sound problem occur in motion process.2nd, match somebody with somebody After conjunction there is radial clearance in inside and outside spline;Under prolonged exercise, it may appear that spline wear causes initial failure.
The content of the invention
The invention solves the problems that there is provided a kind of new constant speed simple in construction, service life length for the shortcoming of above-mentioned prior art Universal joint internal spline axial fixing structure.
The present invention solves the technical scheme that its technical problem is used:This new constant velocity cardan joint female splined shaft is to fixed knot Structure, mainly includes internal spline housing and external splines axostylus axostyle, and the pilot hole of external splines axostylus axostyle and internal spline housing coordinates fixation, interior flower Key housing is provided with bolt hole, bolt hole close to one end of assembling and is equipped with bolt.
The internal spline housing is close to one end of assembling provided with two bolts hole, and two spiro keyhole positions are in the both sides of pilot hole And it is in opposite direction.
The profile of the internal spline housing is cylinder outer race or clutch can.
The internal spline housing is close to one end of assembling provided with a bolt hole, and spiro keyhole position is in the central axial of pilot hole Position.
Bolt is provided with the bolt hole, the bottom of bolt is fixed with nut.
The invention has the advantages that:Structure of the present invention passes through solid to housing internal spline and the locking of axostylus axostyle external splines and axial direction The redesign for determining mode eliminates the axially and radially gap produced after inside and outside spline fitted, thoroughly solves because fit clearance is led The problems such as axial float of cause, abnormal sound and spline initial failure, the feature for the structure that is locked based on female splined shaft to bolt, Meeting on the premise of vehicle installs and uses, it, which is more suitable for constant velocity joint's spline fitted, the vehicle of particular/special requirement, more The deficiency of prior art is mended.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings:
As illustrated, this new constant velocity cardan joint internal spline axial fixing structure, mainly includes internal spline housing 1 and outer The pilot hole 6 of spline axostylus axostyle 2, external splines axostylus axostyle 2 and internal spline housing 1, which coordinates, to be fixed, and the profile of internal spline housing 1 is cylinder outer race Or clutch can.Internal spline housing 1 is provided with bolt hole 3, bolt hole 3 close to one end of assembling and is equipped with bolt 4.Internal spline housing 1 is provided with two bolts hole 3 close to one end of assembling, and two bolts hole 3 are located at the both sides of pilot hole 6 and in opposite direction.
Another way is that internal spline housing 1 is provided with a bolt hole 3 close to one end of assembling, and bolt hole 3 is located at assembling The central axial position in hole 6.Bolt 4 is provided with bolt hole 3, the bottom of bolt 4 can also be fixed with nut 5.Internal spline housing 1 Profile can be cylinder outer race or clutch can.
The present invention is interior by, using processing technologys such as milling flat, draw-bore and groove millings, being realized on constant velocity cardan joint housing Axially double bolts and single bolts are locked structure spline, wherein single bolt locking mechanism, which is divided to, has nut and without two kinds of shapes of nut again State.Two parts above and below internal spline are locked by the screw rod on housing after housing internal spline and axostylus axostyle external splines coordinate, can be with The axially and radially gap produced after inside and outside spline fitted is eliminated, so as to reach the close purpose of inside and outside spline fitted, is solved Due to caused by fit clearance the problems such as axial float, abnormal sound and spline initial failure.
In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitution or equivalent transformation shape Into technical scheme, all fall within the protection domain of application claims.
