According to the automobile steering middle shaft structure, the shaft body is connected with the outer sleeve through the sliding lining, a stuck phenomenon does not occur, the collapsing energy absorption effects are good, the structure is simple, the manufacture is convenient, and damage is not prone to occurrence.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor turning intermediate shaft structure.
Background technology
Along with the fast development of economy and increasing substantially of living standards of the people, the people have also obviously had higher requirement to the quality of life.Compare in the past walking and bicycle epoch, automobile has just like become indispensable a kind of vehicle in current people's life.In automobile, the steering intermediate shaft structure is arranged between deflector and the steering column, is mainly used in the direction of transfer dish by the operation of steering column to deflector.Along with the people to vehicle safety can the raising of requirement, require vehicle to have higher shock resistance collision ability, so then need space between deflector and the steering column can bear the absorption of vehicle energy in the head-on crash process.Therefore, if be arranged on the axial crumple energy-absorbing of steering intermediate shaft structure between deflector and the steering column, then can reduce turning to system to occupant's injury in the frontal crash of vehicles process.
Existing motor turning intermediate shaft structure includes axis body and the outer tube that is arranged between automobile steering device and the steering column, has male splines on one end of axis body, outer tube is provided with female splines, being connected by male splines and female splines between axis body and the outer tube.The stuck phenomenon of spline occurs in existing motor turning intermediate shaft structure easily in the male splines on the axis body and the stressed relative sliding crumple of the female splines on the outer tube process when automobile generation head-on crash, the effect of crumple energy-absorbing is relatively poor.Simultaneously, male splines is set and at outer tube female splines is set at axis body, structure is comparatively complicated, makes inconvenience, and is easier to damage in the forced-slip process, needs to change whole axis body and outer tube after accident occurs, and required cost is higher.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed good, the non-damageable motor turning intermediate shaft structure of a kind of crumple energy-absorbing effect.
The purpose of this utility model can realize by following technical proposal: a kind of motor turning intermediate shaft structure, it is arranged between automobile steering device and the steering column, it is characterized in that, this motor turning intermediate shaft structure comprises axis body, outer tube and is arranged on slide bushing between described axis body and the outer tube, described slide bushing fixed cover is located on the end of described axis body and stressedly can separates the generation relative sliding with described axis body, and described slide bushing fixedly is located in the described outer tube.
Be provided with slide bushing between this motor turning intermediate shaft structure axis body and the outer tube and be connected by slide bushing.When automobile generation head-on crash, axis body is stressed can be separated with slide bushing and relative sliding realization crumple energy-absorbing, reduces in the frontal crash of vehicles process turning to system to occupant's injury.The axis body of this motor turning intermediate shaft structure and outer tube stuck phenomenon can not occur in sliding process, the effect of crumple energy-absorbing is better.The structure of slide bushing is also comparatively simple, easy to make, not fragile simultaneously, and required cost is lower.
In above-mentioned motor turning intermediate shaft structure, described slide bushing be provided with several injecting holes, described slide bushing is fixed on the described axis body by the injecting hole injection moulding.The slide bushing injection moulding is fixed on the axis body, when automobile generation head-on crash, axis body is stressed can be separated with slide bushing and the relative sliding energy-absorbing, between sliding process central axis and slide bushing and axis body and the outer tube all stuck phenomenon can not appear, the effect of crumple energy-absorbing is better, and is simultaneously also not fragile, only slide bushing need be fixed on the axis body by injecting hole again injection moulding during correction maintenance to get final product, reduce required maintenance cost, prolonged its service life.
In above-mentioned motor turning intermediate shaft structure, described injecting hole is evenly distributed on the surface of slide bushing.Slide bushing is fixed on the axis body by being evenly distributed on lip-deep injecting hole injection moulding, each several part is stressed comparatively even, stressed when separating with axis body the absorbent kinetic energy of each several part institute also comparatively even, eliminated local stress and concentrated, be difficult for causing damage, service life is longer.
In above-mentioned motor turning intermediate shaft structure, be interference fit between the madial wall of described slide bushing and described outer tube.Slide bushing and outer tube interference fit, auto against is stressed relative sliding can not to occur yet, and guarantees that it can separate energy-absorbing with axis body in loading process.
In above-mentioned motor turning intermediate shaft structure, described slide bushing adopts rigid material to make.Slide bushing adopts rigid material to make, and separates not fragile fracture in the endergonic process with axis body is stressed, and service life is longer, and required cost is lower, can adopt the mould direct pressing to form, and is comparatively easy.
Compared with prior art, this motor turning intermediate shaft structure has the following advantages:
1, is provided with slide bushing between axis body and the outer tube.The slide bushing injection moulding is fixed on the axis body, and with the outer tube interference fit, when automobile generation head-on crash, axis body is stressed can to separate slip with slide bushing, reach the purpose of crumple energy-absorbing, and stuck phenomenon can not occur in the sliding process, the effect of crumple energy-absorbing is better.
2, the structure of slide bushing is also comparatively simple, easy to make, and is not fragile, and required cost is low, only slide bushing again injection moulding need be fixed on the axis body when keeping in repair after the collision to get final product, and service life is longer.
