Description

A kind of steering spindle
Technical field
The utility model belongs to technical field of automobile accessories, is related to a kind of steering spindle.
Background technology
Steering spindle is the core component of automobile steering system, and the quality of its performance is directly related to traffic and personal safety. Steering spindle is passed through from steering column tube, is supported on the bearing and bushing of steering column tube, and top and the steering wheel of steering spindle are fixed Connection, its underpart is connected with steering gear, and the function of steering spindle is that the steering moment that driver is acted on into steering wheel is passed to turn To device.
Existing steering spindle is all solid construction, although so possessing good rigidity, heavier-weight, and solid The steering spindle of structure does not possess energy-absorbing function, and anti-wound effect is poor.
The content of the invention
The purpose of this utility model be for the above-mentioned problems in the prior art there is provided one kind it is lightweight, can subtract The steering spindle of weak stress concentration.
The purpose of this utility model can be realized by following technical proposal:A kind of steering spindle, including the body being in the form of a column, Characterized in that, described body includes the linkage section one and linkage section two that are coaxially disposed, the outer peripheral face of described linkage section one For the face of cylinder, the outer peripheral face of described linkage section two, which has, to be symmetrical arranged and the cutting face isometric with linkage section two, linkage section two Outer peripheral face between two cutting faces is the arc surface of evagination, and described body also includes first conical surface section, face of cylinder section and the Two conical surfaces section, the length ratio of described first conical surface section, face of cylinder section and second conical surface section is 7:5:3, the first described conical surface The big end of section diameter it is consistent with the diameter of linkage section one and with linkage section one is coaxial is connected, the small end of first conical surface section diameter The diameter of portion and the face of cylinder section it is consistent and with face of cylinder section is coaxial is connected, the big end of described second conical surface section diameter and circle The diameter of cylinder section it is consistent and with face of cylinder section is coaxial is connected, the second conical surface small end of section diameter with outside the maximum of linkage section two Footpath it is consistent and with linkage section two is coaxial is connected, described body axially offers the through hole of the line centered on axis.
In a kind of above-mentioned steering spindle, the described radial direction of linkage section two offers several and set close to second conical surface section Conquassation hole.When steering spindle is by impact, energy-absorbing conquassation effect is played in conquassation hole so that steering spindle deformation is with anti-damage.
In a kind of above-mentioned steering spindle, described linkage section one has a circle spline close to the periphery of first conical surface section Tooth.Spline tooth provides enough clamping forces for bearing inner race, and fiting effect is good.
In a kind of above-mentioned steering spindle, the described first conical surface section less end periphery arc transition of diameter to cylinder Face section, the end outer peripheral face arc transition that described second conical surface section is relatively large in diameter to face of cylinder section.It thus is avoided that stress concentration In the two ends of face of cylinder section.
Compared with prior art, this steering spindle can weaken stress concentration, and structural strength is good, but lightweight, meet now Pursued vehicle is light-weighted to be required, and with preferable energy-absorbing conquassation function, anti-wound is made good use of.

In figure, 1, body;2nd, linkage section one;3rd, linkage section two;3a, cutting face;3b, arc surface;4th, first conical surface section;5、 Face of cylinder section;6th, second conical surface section;7th, through hole;8th, conquassation hole;9th, spline tooth.
Embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model Description, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this steering spindle includes the body 1 being in the form of a column, and body 1 includes the linkage section 1 being coaxially disposed With linkage section 23, the outer peripheral face of linkage section 1 is the face of cylinder, and the outer peripheral face of linkage section 23, which has, to be symmetrical arranged and and linkage section 23 isometric cutting face 3a, outer peripheral face of the linkage section 23 between two cutting face 3a is the arc surface 3b of evagination, and body 1 is also wrapped Include first conical surface section 4, face of cylinder section 5 and second conical surface section 6, the length of first conical surface section 4, face of cylinder section 5 and second conical surface section 6 Than for 7:5:3, first conical surface section 4 diameters it is big end it is consistent with the diameter of linkage section 1 and with the coaxial phase of linkage section 1 Even, the first conical surface small end of 4 diameters of section it is consistent with the diameter of face of cylinder section 5 and with face of cylinder section 5 is coaxial is connected, second bores The face big end of 6 diameters of section it is consistent with the diameter of face of cylinder section 5 and with face of cylinder section 5 is coaxial is connected, second conical surface section, 6 diameters Small end it is consistent with the maximum outside diameter of linkage section 23 and with linkage section 23 is coaxial is connected, body 1 is axially offered with axis Centered on line through hole 7.
This steering spindle employs hollow design in the case where meeting structural strength, meets now pursued vehicle lightweight Requirement, and first conical surface section 4, the face of cylinder section 5 and second the conical surface section 6 setting, linkage section 1 and linkage section can be weakened Stress concentration between 23.
Further describe in detail, the radial direction of linkage section 23 offers three axially arrangement and the conquassation set close to second conical surface section 6 Hole 8, conquassation hole 8 is set through two arc surface 3b, when steering spindle is by impact, and energy-absorbing conquassation effect is played in conquassation hole 8, is made Steering spindle deformation is obtained with anti-damage.Linkage section 1 has a circle spline tooth 9 close to the periphery of first conical surface section 4.First conical surface section The end that the less end periphery of 4 diameters is relatively large in diameter by radius for 4mm arc transition to face of cylinder section 5, second conical surface section 6 Portion's outer peripheral face by radius for 3mm arc transition to the face of cylinder section 5, thus be avoided that stress concentration in the face of cylinder section 5 two ends.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
