Abstract
The utility model relates to a steering shaft with a novel sliding structure and belongs to the technical field of automobile steering columns. The steering shaft comprises a sliding steering shaft and a steering column, wherein an assembly groove is formed in the spline teeth of the sliding steering shaft and an injection layer is arranged on the sliding steering shaft through the assembly groove. The steering shaft disclosed by the utility model has the advantages as follows: the structure is simple; the practicality is good; the injection spline teeth are enabled to slide in the steering column through the sliding steering shaft under the action of external force during the working process, so that the steering column is small in crumple force during crumpling, and the rotating clearance and sliding force are controllable; the problems that an existing clamp-type steering shaft is complex in structure, large in sliding force and difficult in sliding clearance controlling and is not suitable for the upper steering shaft of a steering column assembly are solved; the steering shaft is short in process, simple in manufacturing, and has an ideal sliding effect.
Description
Technical field
The utility model relates to a kind of steering shaft with Novel sliding structure, belongs to car steering tube column technical field.
Background technology
Skid steer axle is a kind of structure of current car steering tube column widespread use, applies this structure and aspect column assy energy-absorbing power, is being convenient to control, thus the safety performance while controlling automobile impacting more easily.Another skid steer axle is also widely used on four-way adjustable steering pipe column.The skid steer axle of current domestic employing is mainly clamping hoop type structure and injection moulding pin injection molding type steering shaft.Clamping hoop type structure is more complicated, and sliding force is large, and glade plane space is wayward, is not suitable for the upper steering shaft application of column assy; Injection moulding pin injection molding type steering shaft cannot slide up and down, and cannot on the adjustable tubing string of four-way, apply.Therefore, be necessary to research and develop a kind of Novel sliding structure that is applicable to the upper steering shaft application of column assy.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, sliding force is easy to the steering shaft with Novel sliding structure of controlling.
The technical solution of the utility model is:
A kind of steering shaft with Novel sliding structure, comprise skid steer axle and steering tube, on the circumference of skid steer axle, be provided with spline tooth, on the inwall of steering tube, corresponding shape is provided with spline, and one end of skid steer axle was movably arranged in steering column by spline tooth and coordinating of spline; It is characterized in that: on the spline tooth of skid steer axle, be provided with fitting recess, on skid steer axle, by fitting recess, be provided with injection molded layers, described fitting recess is radially shape setting on the spline tooth of skid steer axle, described fitting recess quantity is 2-4.
The utility model has the advantage of:
This steering shaft structure with Novel sliding structure is simple, and practicality is good, and in working process, skid steer axle slides injection moulding spline by External Force Acting in steering tube, thereby while making steering tube crumple, crumple power is little, and running clearance and skid force are controlled.Solved existing clamping hoop type steering shaft structure complicated, sliding force is large, and glade plane space is wayward, is not suitable for the problem of the upper steering shaft application of column assy.And operational path of the present utility model is short, make simple.There is desirable shuffle effect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, skid steer axle; 2, steering tube; 3, injection molded layers; 4, fitting recess.
The specific embodiment
This steering shaft with Novel sliding structure comprises skid steer axle 1 and steering tube 2, on the circumference of skid steer axle 1, be provided with spline tooth, on the inwall of steering tube 2, corresponding shape is provided with spline, and one end of skid steer axle 1 was movably arranged in steering tube 2 posts by spline tooth and coordinating of spline.On the spline tooth of skid steer axle 1, radially shape is provided with 2-4 fitting recess 4, on skid steer axle 1, by fitting recess 4, is provided with injection molded layers 3.The effect of fitting recess 4 is the adhesion dynamics that strengthen between skid steer axle 1 and injection molded layers 3, and makes skid steer axle 1 have desirable shuffle effect.
Injection molded layers 3 on the utility model skid steer axle 1 adopts injection machine once to complete, and has stability strong, the feature of dimensionally stable.Because the spline tooth of 3 pairs of skid steer axles 1 of injection molded layers partly forms parcel, in working process, skid steer axle 1 by External Force Acting make injection moulding spline tooth (injection molded layers 3) with skid steer axle 1 in the interior slip of steering tube 2, thereby crumple power is little while making steering tube 2 crumple, running clearance and skid force are controlled.And then it is complicated to have solved existing clamping hoop type steering shaft structure, sliding force is large, and glade plane space is wayward, be not suitable for the problem of the upper steering shaft application of column assy, and injection moulding pin injection molding type steering shaft cannot be applied to the problem on four-way adjustable steering pipe column.
Operational path of the present utility model is short, makes simple.There is desirable shuffle effect.
