Detailed description of the invention
An example of embodiment of the present utility model is represented in Fig. 1～5.Fig. 1 represents the jackshaft device of transfer.Fig. 2 represents the cross section of spline.Fig. 3 represents the amplification cross section of cross axle and hub type needle bearing.Fig. 4 is the amplification view of the first lid.Fig. 5 is the amplification view of the second lid.
The jackshaft device 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 the first cross axle 7 and the first hub type needle bearing 8, the other end have via the second cross axle 107 and the second hub type needle bearing 108, 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 hole 23 of the central authorities of the first arm 22 being shaped on above-mentioned inner spline housing 3, press-in is fixed with metal first lid 31, on the end in the axle portion 15 of the hollow molding chimeric with the central authorities of the second arm 42 of above-mentioned male splined shaft 2, press-in is fixed with metal second lid 33, and is provided with seal 32 in the openend of the internal spline 17 of the hollow of above-mentioned inner spline housing 3.
Hereinafter, the jackshaft device of the automobile steering device of embodiment of the present utility model is further illustrated.
In one end of inner spline housing 3, via the first cross axle 7 and the first hub type needle bearing 8, warpage freely and will not be fixed with the first forked frame 5 with rocking.
At the other end of male splined shaft 2, via the second cross axle 107 and the second hub type needle bearing 108, 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.
The cup-shaped bottom surface of the first hub type needle bearing 8 is connected with the front end face of the first cross axle 7, and the cup-shaped bottom surface of the second hub type needle bearing 108 is connected with the front end face of the second cross axle 107, thus eliminates gap, prevents from rocking.
Male splined shaft 2 is quill shaft, 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.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.
Chimeric on the mid portion of 2 arms 42 (the second arm) of the first forked frame 4 have axle portion 15, metal second lid 33 is had in the press-in of its end, expand on the internal diameter being connected to axle portion 15 by the elastic force of the cylindrical portion of the second lid 33, thus improve sealing, prevent water or dust from invading to spline.
On inner spline housing 3, by plastic working integrally formed with supporting 2 arms 22 (the first arm) of the first cross axle 7, and it is machined with internal spline 17.In the mid portion of 2 arms 22, press-in has metal first lid 31, expands on the internal diameter being connected to hole 23 by the elastic force of the cylindrical portion of the first lid 31, thus improves sealing, prevent water or dust from invading to spline.
In the openend of internal spline 17, seal 32 is installed, the external diameter of internal spline 17 is fixed in seal 32 press-in, the lip of the rubber that seal 32 is had is connected with axle portion 15, and the elasticity from there through rubber improves and the tracing ability in axle portion 15, prevents water or dust from invading to spline.
Being provided with dust cap 50 on the external diameter of inner spline housing 3, dust cap 50 is arranged on the panel divided by the indoor and outdoors of vehicle, prevents water or dust from invading to indoor.
The external diameter of the internal spline 17 of inner spline housing 3 increases to φ 30.7, internal spline 17 and external splines 11 and is all shaped to 24 teeth.When the inner spline housing 3 that external diameter is big is shaped, it is provided with hole 23 at center., it is molded with 16 teeth～20 teeth in the past, but by increasing the number of teeth of spline, and increase while resin can not be thickened the external diameter of spline, improve torsional rigid and improve the stability of steering.
As it has been described above, the jackshaft device of the motor turning device of present embodiment is prevented from water or dust invades to splined interior, even if Long-Time Service, the sliding force of spline also can be stablized, prevent abnormal sound.
