Abstract
The invention discloses a steering transmission intermediate shaft which comprises a spline sleeve and a spline shaft, wherein the spline sleeve is in splined fit with the spline shaft. The other ends, opposite to the matched ends, of the spline sleeve and the spline shaft are provided with universal joint forks respectively. A spline jacket is arranged at the matched position of the spline sleeve and the spline shaft and provided with a grease storage groove, and an air permeable stopper cap is arranged at the outer end of the spline sleeve. Sufficient lubricant can be provided through the grease groove to guarantee reliability in long-term lubrication between the spline sleeve and the spline shaft, vacuumization in the spline sleeve can be avoided by the aid of the air permeable stopper cap to enable the steering transmission intermediate shaft to have fine sliding performance, and accordingly torque fluctuation in steering of a whole vehicle can be effectively avoided, and comfortableness and reliability in steering operation can be improved.
Description
Technical field
The present invention relates to the motor turning technical field, especially relate to a kind of steerage gear tween drive shaft.
Background technology
The client is increasingly high to the car load security requirement, and steering column is as the chassis important component part, and its effect is self-evident in the collision safety of car load.Along with development of technology; In the front and front offset collision process of car load; When causing chaufeur shank and step space by compression for fear of machinery space to the invasion of the space of driving compartment, the steering column mandrel makes its chest injury evil perhaps directly cause chaufeur death, leg room to be extruded and increases the rescue difficulty to chaufeur chest play; Therefore crumple formula tubing string is widely applied on the car load, and shrinkable sliding steering tween drive shaft also is applied on the car load gradually simultaneously.
At present, mostly the steerage gear tween drive shaft is that splined sleeve matches with castellated shaft and is connected that spline fitted helps the flexible of steerage gear tween drive shaft, is convenient to the plant personnel assembling and helps steerage gear tween drive shaft crumple when the car load collision takes place simultaneously.The client requires also increasingly high to the car load traveling comfort, particularly the traveling comfort of handling maneuver.But the steerage gear tween drive shaft can be because of heating up and lacking the lubricated reliability of lubricant influence in long-term use; Splined sleeve is in use inner to be prone to form vacuum, influences the slip of tween drive shaft, reduce the traveling comfort of steering operation, and the inside and outside difference of pressure of splined sleeve is excessive, and it is inner that silt is prone to get into splined sleeve, the reliability that influence is used.
Summary of the invention
Technical matters to be solved by this invention provides a kind of steerage gear tween drive shaft, its objective is in the long-term use process, and tween drive shaft has good lubricated and sliding capability, improves the traveling comfort of steering operation.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of steerage gear tween drive shaft; Comprise splined sleeve and castellated shaft through spline fitted; The other end that described splined sleeve and castellated shaft match is equipped with joint yoke, and described splined sleeve and castellated shaft cooperation place are provided with spline boot, on spline boot, are provided with grease storage groove.
The outer end of described splined sleeve is provided with the permeability to air blanking cover.
Described permeability to air blanking cover is a nylon washer.
Be provided with seal ring in the described spline boot.
Be provided with circular groove with the spline boot cooperation place on the excircle of described splined sleeve.
Described seal ring is a rubber seal, and its internal diameter of the seal ring is less than the external diameter of castellated shaft.
The present invention compared with prior art; Have the following advantages: through grease storage groove is set, enough lubricants are provided on spline boot, guarantee the long-term lubricated reliability between splined sleeve and the castellated shaft; And the permeability to air blanking cover is set at splined sleeve one end; Avoid forming vacuum in the splined sleeve, make it have good sliding capability, improve the traveling comfort and the reliability of steering operation.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification sheets and the figure is made brief description:
Fig. 1 is a steerage gear tween drive shaft organigram of the present invention.
Fig. 2 is the cutaway view along A-A among Fig. 1.
Fig. 3 is the cutaway view along B-B among Fig. 1.
Fig. 4 is a steerage gear tween drive shaft exploded perspective view of the present invention.
Among the figure: 1. splined sleeve, 2. castellated shaft, 3. spline boot, 4. grease storage groove, 5. joint yoke, 6. permeability to air blanking cover, 7. seal ring.
The specific embodiment
Contrast accompanying drawing below, through the description to embodiment, specific embodiments of the invention is done further detailed explanation.
Extremely shown in Figure 4 like Fig. 1; A kind of steerage gear tween drive shaft; Comprise splined sleeve 1 and castellated shaft 2 through spline fitted; Splined sleeve 1 all is welded with joint yoke 5 with the other end that castellated shaft 2 matches, and splined sleeve 1 is arranged with spline boot 3 with castellated shaft 2 cooperation places, is press-fitted the grease storage groove 4 that is full of grease at spline boot 3 one ends.Through grease storage groove 4 enough lubricants are provided, guarantee the long-term lubricated reliability between splined sleeve and the castellated shaft.Can effectively avoid because of shop assembly or logistics transportation causes castellated shaft to separate with splined sleeve through this spline boot, and again with the back phase angle mistake and generation torque fluctuations when causing car load to turn to influences client's driver comfort of the two assembling.Be to produce torque fluctuations when avoiding the universal-joint transfer torque to be provided with certain angle when wherein, two joint yokes design.
Further, be provided with permeability to air blanking cover 6, avoid forming vacuum in the splined sleeve, make it have good sliding capability, improve the traveling comfort and the reliability of steering operation through permeability to air blanking cover 6 in the outer end of splined sleeve 1.Preferably, permeability to air blanking cover 6 is a nylon washer, and cost is low.
Further, in spline boot 3, be provided with seal ring 7, seal ring 7 corresponding splined sleeve ends.Preferably, seal ring is a rubber seal, and its internal diameter of the seal ring is less than the external diameter of castellated shaft, and sealing effectiveness is good.
Preferably, on the excircle of splined sleeve 1, be provided with circular groove, in circular groove, be with rubber ring, improve sealing effectiveness with the spline boot cooperation place.
During assembling, can earlier spline boot, grease storage groove, seal ring be assembled into the component cover, again component cover be cooperated with castellated shaft, after the cleaning, put at component and to coat grease, be combined together with splined sleeve again, easy to assembly, no-float.Have good lubricating property and sliding capability, the generation of torque fluctuations when effectively avoiding the car load steering operation, the traveling comfort and the reliability of raising steering operation.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
