Structure.
Background technique
The structure that car steering tube column is engaged frequently with rack gear improves the retentivity of steering column, and rack structure has
The advantages that good economy performance.But the meeting of rack structure leads to the problem of following two: first, tooth is in incomplete to tooth, in rack gear
When the state of engagement, as shown in Figure 1, handle can not be locked in this position, that is, it not can guarantee handle and lock at an arbitrary position, operate
Person needs every time debugging manually to rack gear fully engaged position set lever；Second, when release handle, the rack gear of engagement can not be complete
Separation, will lead to steering column adjusting force and becomes larger, and adjust irregularity, generate the problems such as adjusting noise.
And designing for these problems urgent need a kind of can guarantee the vapour of motor turning safety by set lever at any time
Vehicle steering column clamping structure.
Summary of the invention
The problem that the present invention breaches the prior art, which devises one kind, to guarantee motor turning safety by set lever at any time
Car steering tube column clamping structure.
In order to achieve the above object, the present invention devises a kind of improved car steering tube column clamping structure, comprising: upper tube
Column, U-shaped frame, handle spring, it is characterised in that: the outer sheath of the upper tubing string be equipped with U-shaped frame, handle spring from upper tubing string one
Side penetrates tubing string and U-shaped frame, and the penetration end of handle spring is arranged with axle spring rack gear, and the front of axle spring rack gear is fixed
There is axial rack gear, the front of axial rack gear is equipped with the soft limit of right radial direction, is arranged with radial spring rack gear, diameter in the right soft limit of radial direction
It is arranged with radial rack gear on spring rack gear, is equipped in front of radial rack gear and tightens nut；The both ends of the radial spring rack gear and U
Type frame is mutually fixed by the way of laser welding.
The side of the soft limit of right radial direction is double card foot, double card foot and axial direction rack gear phase clamping, the right soft limit of radial direction
The other side is four card bases, and four card bases pass through radial spring rack gear and radial rack gear phase clamping.
The shape of the radial direction rack gear is " several " font, and latch is distributed in the outside of " several " word bending part.
The shape of the radial spring rack gear is hollow rectangle, and latch is distributed in the outside of two long sides, radial bullet
The center of two short sides of spring rack gear is equipped with welding boss.
The shape of the axle spring rack gear is hollow rectangle, and latch is distributed in the inside of two long sides, axial bullet
The center of two short sides of spring rack gear is equipped with engaging boss.
The cross section of the radial spring rack gear and axle spring rack gear is inverted " several " fonts.
Compared with prior art, the present invention axle spring rack gear and radial spring rack gear are used, when set lever, because
For the deformability of spring, generation of the tooth to tooth phenomenon is avoided, while having saved bit by bit deformation potential, when release handle, deformation
Potential energy is released, and flicks the rack gear of engagement, so that driver is adjusted smoothly, and the configuration of the present invention is simple, practical and convenient, processing
It is at low cost.
Detailed description of the invention
Fig. 1 is that existing steering column clamping structure the case where tooth is to tooth figure occurs.
Fig. 2 is explosive view of the invention.
Referring to fig. 2,1 is handle spring, and 2 be axle spring rack gear, and 3 be axial rack gear, and 4 be the soft limit of right radial direction, and 5 be diameter
To spring rack gear, 6 be radial rack gear, and 7 is tighten nut, and 8 be upper tubing string, and 9 be U-shaped frame.
Specific embodiment
In conjunction with attached drawing, the present invention will be further described.
Referring to fig. 2, the present invention devises a kind of improved car steering tube column clamping structure, comprising: upper tubing string 8, U-shaped frame
9, the outer sheath of handle spring 1, the upper tubing string 8 is equipped with U-shaped frame 9, and handle spring 1 penetrates upper tubing string 8 from the side of upper tubing string 8
With U-shaped frame 9, the penetration end of handle spring 1 is arranged with axle spring rack gear 2, and the front of axle spring rack gear 2 is fixed with axial tooth
Item 3, the front of axial rack gear 3 is equipped with the soft limit 4 of right radial direction, is arranged with radial spring rack gear 5 in the right soft limit 4 of radial direction, radial
It is arranged with radial rack gear 6 on spring rack gear 5, is equipped in front of radial rack gear 6 and tightens nut 7；The both ends of the radial spring rack gear 5
It is mutually fixed by the way of laser welding with U-shaped frame 9.
The side of the right soft limit 4 of radial direction is double card foot in the present invention, and double card foot and the 3 phase clamping of axial rack gear, right radial direction are soft
The other side of limit 4 is four card bases, and four card bases pass through radial spring rack gear 5 and the 6 phase clamping of radial rack gear.
The shape of radial rack gear 6 is " several " font in the present invention, and latch is distributed in the outside of " several " word bending part.
The shape of radial spring rack gear 5 is hollow rectangle in the present invention, and latch is distributed in the outside of two long sides, diameter
Welding boss is equipped with to the center of two short sides of spring rack gear 5.
The shape of axle spring rack gear 2 is hollow rectangle in the present invention, and latch is distributed in the inside of two long sides, axis
Engaging boss is equipped with to the center of two short sides of spring rack gear 2.
The cross section of radial spring rack gear 5 and axle spring rack gear 2 is inverted " several " fonts in the present invention.
In specific implementation, by taking radial spring rack gear is engaged with radial rack gear as an example: since spring rack gear is in "Ji" type,
Its two lateral flange is flipped up, and so that its flange with tooth form is had certain deformability, when radial spring rack gear and radial teeth
When item is in the state not engaged, set lever, radial rack gear, which presses to radial spring rack gear, makes its deformation, guarantees that handle is normal
Locking, and enough retentivities are provided, tooth is improved to tooth problem；Since radial spring rack gear and handle spring are in handle locking
Flexible deformation is generated under state, when handle unclamps, discharges elastic potential energy, it is ensured that the tooth form of engagement separates, and reduces adjusting force,
Adjust driver smooth.Similarly, axial rack gear is similar with above-mentioned example with the theory of engagement of axle spring rack gear.
Present invention employs axle spring rack gears and radial spring rack gear, when set lever, because spring is deformable
Property, generation of the tooth to tooth phenomenon is avoided, while having saved bit by bit deformation potential, when release handle, deformation potential is released, and is flicked
The rack gear of engagement, so that driver is adjusted smoothly, and the configuration of the present invention is simple, practical and convenient, processing cost is low.
