After the capturing position in position calibrator unit mounting hole 101 of position correction part 30, can use
Be fixed on position correction part on wheel hub 11 by installation bolt.Below will be made of how to determine position correction
Position of the part 30 on wheel hub 11 is described.
In the assembling process of vehicle steering component 100, position correction part 30 is arranged on fixed
In the frock 200 of position, as shown in figure 4, Fig. 4 is to show position according to an embodiment of the invention
The scheme of installation of calibrator unit and wheel hub.The longitudinal center axis D2 of position correction part 30 and fixed
Position frock 200 longitudinal center axis E X-direction overlap, and position correction part 30 peace
Dress part 31 is directed at the position on wheel hub 11 on vertical direction (direction of longitudinal center axis E)
Calibrator unit mounting hole 101.By positioning tool 200 in the movement of X-direction, position can be driven
Calibrator unit 30 is moved in X-direction, so by determining the position of positioning tool 200, it is possible to
Determine the position of position correction part 30.As shown in figure 4, the left and right sides of positioning tool 200 is stretched out
Strong balanced controls 201.Make dynamic balance mechanism by moving horizontally positioning tool 200 in X direction
201 reach balance, can find between a pair of test points of the left and right of the medial surface of spoke part 12 two
Cental axial position.When dynamic balance mechanism 201 reaches dynamic balance, the longitudinal center of positioning tool 200
Central axes between axis E and a pair of left and right test points of the medial surface of spoke part 12.
Central axis between a pair of left and right test points of the medial surface of spoke part 12 is defined as a pair of spokes
Longitudinal center axis between the medial surface of part 12.Now vertical central axis of position correction part 30
Longitudinal center axis between the medial surface of line D2 and spoke part 12 is substantially weighed in the horizontal direction
Close.Preferably, in the present embodiment, installation site of the position correction part 30 on wheel hub 11 is true
It is set to, longitudinal center axis and a pair of disc portions of a pair of the location holes 37 on position correction part 30
The longitudinal centre line divided between 12 medial surface is substantially overlapped in the horizontal direction.Determine position correction
Behind the position in the horizontal plane of part 30, the position in the horizontal plane of holding position calibrator unit 30 is not
Become, it is seated on the position correction member mounting holes 101 of wheel hub 11 vertically, and use screw element
It is fixed in place.
In attached embodiment illustrated in fig. 2, air-bag module 20 and a pair of shapes of spoke part 12
Into lateral clearance (along the X-direction in Fig. 2) refer to air-bag module 20 top outer side
Gap between edge and a pair of medial surfaces of spoke foaming body relative with it.In actual product, phase
To a pair of spokes on decoration can also be installed, decoration is integrated with the functions such as sound equipment control handle.
In another embodiment of the present invention, integrated decoration block, air bag group are installed on a pair of spokes
Distinguish with the medial surface of the integrated decoration block being arranged on above a pair of spokes at the top outer edge of part 20
It is formed with gap.The step that position correction part 30 is arranged on wheel hub 11 is in integrated decoration block peace
Carried out after being attached on a pair of spokes.The position of position correction part 30 is by positioning tool 200
It is mobile, and find in the integrated decoration block relative with the top outer edge of air-bag module 20
Axial centerline between the test point of left and right two of side so that in the longitudinal direction of positioning tool 200
Central axis between heart axis E and two test points of integrated decoration block is substantially overlapped.Now position
The longitudinal center axis D2 of calibrator unit 30 also with the integrated decoration block on a pair of spokes
The central axis of side is substantially overlapped in X-direction, and holding position calibrator unit 30 is in the horizontal plane
Position is constant, and it is seated on the position correction member mounting holes 101 of wheel hub 11 vertically, is used in combination
Screw element is fixed in place.
In the present invention, functional part can be also provided with wheel hub 11, functional part for example can be electricity
Contact component, position correction part 30 can be indirectly mounted on wheel hub 11 by functional part.Position
The determination mode for putting position of the calibrator unit 30 on functional part is straight with position correction part 30
The determination mode for connecing position on wheel hub 11 is identical, has been discussed in detail before this, herein
Repeat no more.
In the present invention, it will be appreciated by those skilled in the art that air-bag module 20 and position school
The location structure that quasi-component 30 cooperates is not limited only to the structure shown in Fig. 2, as long as should
Location structure can limit air-bag module 20 and position correction part 30 in the horizontal plane relative
Motion.For example, location hole 37 is alternatively formed on air-bag module 20, accordingly
Ground, locating dowel 21 is also alternatively formed on position calibrator unit 30.And for example, location structure can
Be single structure given shape mating part, limit air-bag module 20 and position correction
The relative motion in the horizontal plane of part 30.
Similarly, the shape and structure of position correction part 30 are engaged with position correction part 30
Position correction member mounting holes 101 on wheel hub 11 are also not limited only to shown in Fig. 3, both
Other modes can be substituted or be used, as long as position correction part 30 can be fixed with defined location
On wheel hub 11.For example, according to one embodiment, chute can be formed on wheel hub 11,
Sliding block is formed with position calibrator unit 30, position correction part 30 is by chute and the cunning of sliding block
It is dynamic to coordinate the adjustment for realizing the installation site relative to wheel hub 11, lead to after finding both position locations accurately
Fixed structure is crossed to fix.
While the invention has been described with reference to exemplary embodiments thereof, however, it is understood that the present invention not
It is limited to the construction of above-described embodiment and method.On the contrary, it is intended to cover various modifications and be equal to
Configuration.Although in addition, showing the various of disclosed invention in various exemplary combination bodies and construction
Element and method and step, but other combinations including more, less element or method also fall at this
Within the scope of invention.
