Description
Technical field
The utility model is related to a kind of slip steering spindle, belongs to steering column for vehicles technical field.
Background technology
The steering spindle of automobile is the important spare part of closure disk and steering assembly, and its Main Function is by steering wheel
Moment of torsion pass to steering assembly.With the development of society, in order to improve security performance during automobile impacting, existing slip
Steering spindle typically all possesses the function of energy-absorbing.But existing steering spindle is mainly clamping hoop type structure and injection molding type structure, clamping hoop type
Complex structure, sliding force is big, and glade plane space is uncontrollable, it is impossible to meet actual use needs.Injection molding type steering spindle cannot
Slide up and down, cause the length of steering spindle unadjustable；A kind of can solve the problem that what existing steering spindle had it is therefore desirable to research and develop
The steering spindle of problem above, to meet people's use the need for.
The content of the invention
The purpose of this utility model is：There is provided that a kind of simple structure, stable performance, sliding force be small, length-adjustable cunning
Dynamic steering spindle.
The technical solution of the utility model is：
One kind slides steering spindle, and it is made up of steering spindle, steering tube, retainer, ball, needle roller, upper section fork and lower section fork；
One end of steering spindle is welded with section fork, and one end of steering tube is welded with lower section fork；It is characterized in that：On the periphery of steering spindle
Spline is provided with, correspondence shape is provided with spline on the inwall of steering tube, one end of steering spindle is installed by retainer activity
In steering tube；Described retainer is cylindrical shape；It is respectively arranged with and spline pair on the periphery of retainer and on inwall
The spline tooth answered；Multiple balls are fitted with described spline tooth separately；Multiple is fitted with the spline tooth of ball side
Needle roller；Described spline tooth is fitted and connected with spline.
Retainer is extended in the upper surface and lower surface of described ball upper surface and lower surface and needle roller, and respectively with
Corresponding spline is fitted and connected.
Assembling annular groove is provided with the periphery of described steering tube one end；Installed by assembling annular groove one end of steering tube
There is dust cover.
The utility model has the advantage of：
The slip steering shaft structure is simple, practicality is good, in the course of work, steering spindle by external force act on make retainer,
Ball and needle roller are slided in steering tube, so as to the crumple power for reducing steering tube is small.Existing clamping hoop type steering spindle is solved to deposit
Some complex structures, the big problem of sliding force.And the slip steering spindle can as needed adjust the depth of insertion steering tube, so that
The purpose of adjustment length is reached, solving injection molding type steering spindle cannot slide up and down, the uncontrollable problem of length meets
The need for people's use.

Specific embodiment
The slip steering spindle is by steering spindle 1, steering tube 2, retainer 3, ball 4, needle roller 5,7 structures of upper section fork 6 and lower section fork
Into；One end of steering spindle 1 is welded with section fork 6, and upper section fork 6 is connected with vehicle steering, and one end of steering tube 2 is welded with lower section
Fork 7, lower section fork 7 is connected with steering assembly.
Spline 8 is provided with the periphery of steering spindle 1, correspondence shape is provided with spline 8 on the inwall of steering tube 2, turns
It is movably arranged in steering tube 2 by retainer 3 to one end of axle 1.Assembling annular groove is provided with the periphery of the one end of steering tube 2
10；One end of steering tube 2 is provided with dust cover 11 by assembling annular groove 10, sets the purpose of dust cover 11 and is：Prevent dust from entering
Enter in steering tube 2, influence the normal of the slip steering spindle to use.
Retainer 3 is cylindrical shape；It is respectively arranged with the periphery of retainer 3 and on inwall and the corresponding flower of spline 8
Key teeth 9；Spline tooth 9 is fitted and connected with corresponding spline 8.Multiple balls 4 are fitted with described spline tooth 9 separately；
Multiple needle rollers 5 are fitted with the spline tooth 9 of the side of ball 4；The upper surface of ball 4 and the upper surface and lower end of lower surface and needle roller 5
Retainer 3 is extended in face, and is fitted and connected with corresponding spline 8 respectively.
The purpose for setting ball 4 and needle roller 5 is：Spline tooth 9 and the coefficient of friction of spline 8 are reduced, so that reduce this should
Slide crumple power during steering spindle crumple.In addition another purpose of setting needle roller 5 is：So that steering spindle 1 passes through needle roller 5
More preferable transmitting torque.
When the slip steering spindle needs adjustment length, it is only necessary to be pressed into or pull out steering tube 2 i.e. by steering spindle 1 using external force
Can.
The slip steering shaft structure is simple, practicality is good.The complex structure that existing clamping hoop type steering spindle has is solved,
The big problem of sliding force.Solving injection molding type steering spindle again cannot slide up and down, the uncontrollable problem of length, meet people
The need for use.
