Description
Technical field
The present invention relates to a kind of vehicle component and method for designing, particularly a kind of opening internal spline and its method for designing.
Background technology
Jackshaft in automobile steering system be commonly designed when transmission high torque is needed spline connection steering column and
Steering gear, in order to require that spline is fitted close in assembling facility and work, usual internal spline is designed to open-type fitted bolt again
Tighten, because jackshaft is often changed direction rotation in the course of the work, if spline fitted it is bad can cause spline abnormal sound with
And there is the not good phenomenon of feel, influence vehicle NVH etc.;Therefore when the design of motor turning jackshaft spline connection needs to ensure long
Between good tight fit.
(Note:NVH is the english abbreviation of noise, vibration and sound vibration roughness (Noise, Vibration, Harshness),
This is global question for weighing automobile making quality, and it is experienced as most directly and most surface to user vehicle;Car
NVH problems be the major vehicle manufacturing enterprises of international automobile industry and parts enterprises concern one of problem;There is statistics
It has been shown that, the failure problems that vehicle there are about 1/3 are that have relation with the NVH problems of vehicle, and there is nearly 20% R & D Cost in each major company
Consumption is on the NVH for solving the problems, such as vehicle.)
Existing steering intermediate shaft internal spline modular construction is as shown in Figure 1:It is made up of opening internal spline universal joint section fork, is generally opened
Intraoral spline material is steel, and supporting bolt selection standard part is open internal spline structure as shown in Figure 2, in unassembled shape
Internal spline shape is into regular toroidal under state, and the unthreaded hole and screwed hole of bolt hole are coaxial;Such as the institute of accompanying drawing 3 after interior external splines assembling
Show, the gap of internal spline and external splines is circumferential uniform, and in order to assemble facility, gap is larger, after interior external splines assembling and tighten spiral shell
After bolt as shown in Figure 4, pictorial diagram is as schemed(Accompanying drawing 5)Shown, pictorial diagram coordinates the spiral shell of M10 × 1.5 for existing opening internal spline
Bolt, prefastening torque 50N.m more apparent can find out that the spline fitted of nearly bolt is seriously mutually extruded, and the spline of remote bolt is then present
Larger gap, opening internal spline is in irregular shape, and the external splines for coordinating still is regular circle shapes shape, causes overall co-ordination not
It is good.Existing opening internal spline has the following disadvantages:
(1)Gap is too small between interior external splines(Precision), cause assembling difficult;
(2)Bolt does not tighten preceding internal spline into regular circle shapes, and bolt tightens rear internal spline and is deformed into non-circular, causes interior external splines
Poor fit, or even there is part tooth by conquassation phenomenon, cause actual cooperation not corresponded with Theoretical Design;
(3)Bolt needs to twist high torque, need to select larger sized bolt, and residual pretightning force weakens larger, is easily caused abnormal sound
The tooth for producing and being likely to occur opening internal spline or external splines produces plastic deformation etc.;
(4)The unthreaded hole and screwed hole of bolt hole are coaxial during free state, then during confined state(Bolt is tightened)Due to flower in opening
Key compressive deformation, produces the unthreaded hole and screwed hole into not coaxial phenomenon of bolt hole, and bolt not only receives prefastening force, while by bending
Power causes bolt to deform, influence service life.
