Detailed description of the invention
An example of embodiment of the present utility model is represented in Fig. 1, Fig. 2, Fig. 3, Fig. 4.Fig. 1 represents the jackshaft device 1 of transfer.Fig. 2 represents the axial groove of jackshaft device 1.Fig. 3 represents the cross section in the axle portion with axial groove.Fig. 4 represents the cross section of spline 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 external splines 11 implements resinous coat 13 in spline type mandrel portion 12,
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,
In the above-mentioned axle portion 15 of above-mentioned male splined shaft 2, it is provided with between zigzag key 14 and external splines 11 4 axial grooves 10 of continuous print by plastic working every 90 degree of ground.
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.
