Rear universal joint is pitched, and the right side of described rear universal joint fork is provided with the first connecting shaft, outside the right-hand member of described first connecting shaft is provided with
Spline, the outside of described external splines is provided with installation set, and the described bottom installing set is provided with projection, described projection is provided with
Installing hole, the right side of described installation set is provided with the second connecting shaft, and the right-hand member of described second connecting shaft is provided with involute spline,
The top of described involute spline is provided with plane.
Preferably, described plane is arranged at the top center of involute spline.
Preferably, the described left side inner chamber installing set is provided with the spline matched with external splines.
Preferably, described projection is semicircular arc, and projection is positioned close to install the bottom left of set.
Preferably, described set of installing is cylindrical structure.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, easy to use, and
And use spline to be connected with power transmission shaft so that it is not easy abrasion in use, thus improves service life, and use binodal instead
(connecting with spline housing transition) plays the problem being difficult to assemble after solving Frame Welding modification, easy for installation.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is that this utility model splits structural representation.
In figure: 1 internal spline, universal-joint fork before 2,3 Hooke's joint assemblies, 4 rear universal joint forks, 5 first connecting shafts, 6
External splines, 7 installation set, 8 projections, 9 second connecting shafts, 10 involute splines, 11 planes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Fig. 1-2, a kind of technical scheme of this utility model offer: universal connecting shaft assembly under a kind of electric motor car, bag are provided
Include front universal-joint fork 2, be provided with circular port at the Left-side center of described front universal-joint fork 2, in circular port, be provided with internal spline 1,
The right side inner chamber of described front universal-joint fork 2 is provided with Hooke's joint assembly 3, the right side of described Hooke's joint assembly 3
Being provided with rear universal joint fork 4, the right side of described rear universal joint fork 4 is provided with the first connecting shaft 5, the right side of described first connecting shaft 5
End is provided with external splines 6, and the outside of described external splines 6 is provided with installation set 7, and the described bottom installing set 7 is provided with protruding 8,
Being provided with installing hole on described protruding 8, the right side of described installation set 7 is provided with the second connecting shaft 9, described second connecting shaft 9
Right-hand member is provided with involute spline 10, and the top of described involute spline 10 is provided with plane 11.
Wherein, described plane 11 is arranged at the top center of involute spline 10, and the left side inner chamber of described installation set 7 sets
It is equipped with the spline matched with external splines 6, it is simple to connect, the most easy to wear, improve transmission efficiency, described protruding 8 is semicircular arc,
And projection 8 is positioned close to install the bottom left of set 7, it is simple to install and connect, described installation set 7 is cylindrical structure.
Operation principle: during use, plane 11 is equivalent to the effect of keyway, when the spline phase of involute spline 10 with power transmission shaft
