Described male splined shaft 2 is made up of axle portion 15 and external splines 11,
Described inner spline housing 3 and described male splined shaft 2 are chimeric in the way of can transmitting torque and sliding axially freely, and the jackshaft device of described automobile steering device is characterised by,
On the openend of described inner spline housing 3, chamfering 22, groove 21 and internal spline 17 it is machined with successively from openend, being provided with C-shaped ring 20 on described groove 21, the internal diameter of described C-shaped ring 20 and the outer path interferometer of described external splines 11 prevent described male splined shaft 2 from coming off from described inner spline housing 3.
The effect of utility model
By this structure, prevent external splines from coming off from internal spline, it is possible to transfer state when vehicle assembles to be kept regularly relative to each product, improve assembleability.
Accompanying drawing explanation
Fig. 1 is the figure representing embodiment of the present utility model.
Fig. 2 is the enlarged drawing representing the major part in Fig. 1.
Detailed description of the invention
An example of embodiment of the present utility model is represented in Fig. 1, Fig. 2.Fig. 1 represents the jackshaft device 1 of transfer.Fig. 2 is the enlarged drawing of major part.
The jackshaft device 1 of the automobile steering device of present embodiment at one end has the inner spline housing 3 combined freely by the first forked frame 5 warpage via first cross axle the 7, first hub type needle bearing 8 and the first thrust component 9, the other end have via second cross axle the 107, second hub type needle bearing 108 and the second thrust component 109, second forked frame 4 and third fork shape frame 6 warpage are combined freely and with the male splined shaft 2 of above-mentioned second forked frame 4 solder bond
Above-mentioned male splined shaft 2 is made up of axle portion 15 and external splines 11,
Above-mentioned inner spline housing 3 and above-mentioned male splined shaft 2 are chimeric in the way of can transmitting torque and sliding axially freely, and the jackshaft device of above-mentioned automobile steering device is characterised by,
On the openend of above-mentioned inner spline housing 3, chamfering 22, groove 21 and internal spline 17 it is machined with successively from openend, being provided with C-shaped ring 20 on above-mentioned groove 21, the internal diameter of above-mentioned C-shaped ring 20 and the outer path interferometer of above-mentioned external splines 11 prevent above-mentioned male splined shaft 2 from coming off from above-mentioned inner spline housing 3.
Hereinafter, the jackshaft device 1 of the automobile steering device of embodiment of the present utility model is further illustrated.
In one end of inner spline housing 3, via first cross axle the 7, first hub type needle bearing 8 and the first thrust component 9, warpage freely and will not be fixed with the first forked frame 5 with rocking.
The other end at male splined shaft 2, via second cross axle the 107, second hub type needle bearing 108 and the second thrust component 109, warpage is combined with the second forked frame 4 and third fork shape frame 6 freely, and makes this second forked frame 4 and third fork shape frame 6 to fix with rocking.
First thrust component 9 and the second thrust component 109 by molding synthetic resin, reduce rocking of the first cross axle 7 and the first hub type needle bearing 8 and rocking of the second cross axle 107 and the second hub type needle bearing 108 respectively by the elasticity of resin.
Male splined shaft 2 is made up of axle portion 15, external splines 11 and zigzag key 14, and male splined shaft 2 makes the first forked frame 4 and zigzag key 14 be fitted together to, and is combined by calking processing department 16 and welded joint 18.It is chimeric in the way of can transmitting torque and sliding axially freely that external splines 11 implements resinous coat 13, inner spline housing 3 and male splined shaft 2 in spline type mandrel portion 12.
On the openend of inner spline housing 3, it is machined with chamfering 22, groove 21 and internal spline 17 successively from openend, above-mentioned groove 21 is provided with C-shaped ring 20.Even if chamfering 22 also will not make the inclination of its depth shallower being processed in the way of coming off as made groove 21 C-shaped ring 20 to be arranged in groove 21.Groove 21 is machined on the position not having chamfering 22 of internal spline 17 end, and is machined on the position not across internal spline 17, and is located on the position that overlap when internal spline 17 is processed groove 21 cannot arrive.
By being provided with C-shaped ring 20 on groove 21, and make the internal diameter of above-mentioned C-shaped ring 20 and the outer path interferometer of external splines 11 to prevent male splined shaft 2 from coming off from above-mentioned inner spline housing 3.
The jackshaft device that external splines comes off from internal spline and assembleability is excellent is prevented as it has been described above, become.
