Abstract
The utility model provides a car steering operation mechanism's conquassation energy -absorbing structure, including lower of steering spindle top tube and steering spindle, off -axial side is equipped with the tooth's socket structure under the steering spindle, and the alveolar surface is equipped with the elastic construction, lower of the lower extreme of steering spindle top tube and steering spindle are for the spline tooth cooperates, and lower elastic construction thickness with the cooperation alveolar surface of steering spindle top tube of steering spindle is less than the elastic construction thickness that does not cooperate the alveolar surface. The alveolar surface of lower of steering spindle be equipped with the elastoplast, lower lower extreme with the steering spindle top tube of steering spindle passes through the spline tooth cooperation, conquassation power is invariable, the energy absorption is big, simple structure easily makes moreover, has promoted the rigidity of steering operation mechanism and the travelling comfort of driver's operation effectively.
Description
Technical field
The utility model belongs to auto parts and components field, especially relates to a kind of collapse energy-absorption structure of automobile steering operation mechanism.
Background technology
Along with the production in enormous quantities of automobile product and the great development of auto-industry, automobile has become the indispensable walking-replacing tool of the mankind.To the Proper Match between the different corner of left and right turn wheel, steering swivel system is by ensureing that automobile is along imagination orbiting motion, it is made up of steering control mechanism, deflector and steering gear.Steering system comprises steering handwheel, steering shaft, steering column, collapse structure is generally arranged on steering column or steering shaft, be used for improving the safety of frontal crash of vehicles, reduce the injury that driver causes in secondary collision, under the prerequisite not reducing steering system stiffness, improve the traveling comfort of driving.The crushing force fluctuation of the collapse energy-absorption structure of prior art is large, and energy absorption is little, very easily causes secondary injury to driver, and can reduce the rigidity of steering swivel system, affects handling comfort.
Summary of the invention
In view of this, the utility model is intended to the collapse energy-absorption structure proposing a kind of automobile steering operation mechanism, very easily secondary injury is caused to driver with the collapse energy-absorption structure solving prior art, reduce the rigidity of steering swivel system, and affect the problem of operation comfort.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of collapse energy-absorption structure of automobile steering operation mechanism, comprise pipe and steering shaft lower shaft on steering shaft, tooth slot structure is provided with outside described steering shaft lower shaft, and alveolar surface is provided with elastic construction, on described steering shaft, the lower end of pipe is that spline tooth coordinates with steering shaft lower shaft, and on steering shaft lower shaft and steering shaft, the elastic construction thickness of the cooperating teeth groove face of pipe is less than the elastic construction thickness of non-cooperating teeth groove face.
Further, described elastic construction is plastics.
Further, described elastic construction is styrene TPE plastics.
Further, described alveolar surface and elastic construction are glued together.
Further, described alveolar surface and elastic construction resin-bonded by thermoplastic polystyrene together with.
Further, on described steering shaft, pipe passes through together with interference fit with steering shaft lower shaft.
Relative to prior art, the collapse energy-absorption structure of a kind of automobile steering operation mechanism described in the utility model, has following advantage:
The alveolar surface of described steering shaft lower shaft is provided with elastoplast, and steering shaft lower shaft is coordinated by spline tooth with the lower end of pipe on steering shaft, and crushing force is constant, energy absorption is large, and structure is simple, be easy to manufacture, effectively improve the traveling comfort that the rigidity of steering operation mechanism and driver operate.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the collapse energy-absorption structure of a kind of automobile steering operation mechanism described in the utility model embodiment;

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of collapse energy-absorption structure of automobile steering operation mechanism, comprise pipe 1 and steering shaft lower shaft 2 on steering shaft, tooth slot structure is provided with outside described steering shaft lower shaft 2, and alveolar surface is provided with elastic construction, on described steering shaft, the lower end of pipe 1 is with steering shaft lower shaft 2 for spline tooth coordinates, and steering shaft lower shaft 2 is less than the elastic construction thickness of non-cooperating teeth groove face 3 with the elastic construction thickness of the cooperating teeth groove face of pipe 1 on steering shaft.
Preferably, described elastic construction is plastics; More preferably, described elastic construction is styrene TPE plastics.
Preferably, described alveolar surface and elastic construction are glued together; More preferably, described alveolar surface and styrene TPE plastics resin-bonded by thermoplastic polystyrene together with.
Preferably, on described steering shaft, pipe 1 and steering shaft lower shaft 2 pass through, together with interference fit, to eliminate tolerance clearance, increase coupling stiffness.
The styrene TPE plastics of non-cooperating teeth groove face 3 prevent the axial motion of pipe 1 under low axial force on steering shaft, maintain the normal use of steering control mechanism, on steering shaft, pipe 1 compresses the stupid ethene TPE plastics of non-cooperating teeth groove face 3 bonding under high axial force simultaneously, make to produce larger friction force between the inside face of pipe 1 on stupid ethene TPE frosting and steering shaft, to reach energy-absorbing effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
